Description:FIELD OF THE INVENTION
[001] The present invention relates generally to material categorization and handling systems for vehicles, and more particularly to a vehicle-based system and method for categorizing and suctioning spoil materials, such as solid-spoil (e.g., dust, debris) and liquid-spoil (e.g., water, sludge), encountered in industrial, construction, or municipal operations.

BACKGROUND OF THE INVENTION

[002] Suction-based material handling vehicles, such as suction excavators, vacuum trucks, and dust collectors, are commonly employed to remove spoil materials from the ground or other surfaces. Conventionally, such vehicles are designed to handle either solid materials or liquid materials exclusively, necessitating the use of separate vehicles depending on the type of spoil to be removed. For instance, a suction excavator might be equipped with a dust filtration system for dry solids, while a vacuum truck might be optimized for liquid suction with shut-off valves and drainage systems. While these conventional approaches have been effective to some extent, they suffer from several limitations. The use of separate vehicles for solid and liquid spoil increases operational costs, requiring fleets to maintain and deploy multiple specialized units, which complicates logistics and resource allocation. Multi-purpose vehicles, although more versatile, place a significant burden on the operator to accurately identify the spoil type and manually adjust the system accordingly. This manual selection process is prone to human error, particularly in environments where spoil characteristics are not immediately apparent. For example, an operator/user might mistakenly categorize and operate the vehicle for solid spoil suction when liquid spoil is present, leading to clogging or damage to filtration systems, suction lines, or other components. Conversely, configuring the vehicle for liquid suction when handling solid spoil can reduce efficiency or cause mechanical strain on the system. In prior art solutions, such as suction excavators and vacuum trucks, there is typically no provision for real-time detection of spoil properties (e.g., solid versus liquid) at the point of suction. Instead, operators rely on subjective judgment, which can lead to inconsistent performance and unintended damage to critical components like dust filtration tanks, shut-off valves, or suction pumps. Furthermore, conventional systems often lack a structured means to guide the operator or verify the correctness of their mode selection, leaving no record of operational decisions. This absence of accountability poses challenges for manufacturers and operators alike, particularly in resolving disputes over warranty claims or identifying the cause of equipment failures. As a result, there remains a need for a vehicle-based suction system that can reliably categorize spoil materials, guide the operator in selecting the appropriate suction mode, and ensure efficient and safe handling of both solid and liquid spoil without risking equipment damage.

[003] For instance, patent application WO2000058566 discloses a suction excavator which discloses suction of spoil but fails to categorize spoil in liquid-spoil and solid-spoil and manually selecting suction handling system.

[004] Therefore, there is a need for a vehicle-based system and method for categorizing and suctioning spoil materials.

DETAILED DESCRIPTION OF THE INVENTION
[009] Referring now to the drawings, Figures 1 to 2, where the present invention is generally referred to with numeral (100), it can be observed that a vehicle-based spoil categorizing and suction handling system, in accordance with an embodiment, is provided which includes a vessel (10), a suction-hose (20), a sensor-unit (30), a control-unit (40), a solid-spoil-indicator (50a), a liquid-spoil-indicator (50b), a solid-spoil-actuator (60a), a liquid-spoil-actuator (60b), a suction-unit (70), an exhaust-unit (80), a pipe-assembly (90), a solid-spoil suction-unit (91) and a liquid-spoil suction-unit (92).

[010] The vessel (10) is disposed on a chassis (05a) of a vehicle (05). The vessel (10) is an enclosed unit which facilitates receiving of the spoil (02) therewithin and enable suction.

[011] The suction-hose (20) is carried in vicinity of the spoil (02) which can be disposed on the ground (03) or in a hole drilled on the ground (03) and carries spoil (02) from the ground (03) into the vessel (10). The suction-hose (20) is defined with a vessel-portion (20a) and a suction-portion (20b). The vessel-portion (20a) is in functional-connection with the vessel (10). The suction-portion (20b) is portable in vicinity of spoil (02) which is disposed on the ground (03). The

[012] The sensor-unit (30) is disposed on the suction-portion (20b) of the suction-hose (20) so that the sensor-unit (30). The sensor-unit (30) is defined to sense parameters of spoil (02) disposed on the ground (03). In accordance with one embodiment, the sensor-unit (30) includes an ultrasonic-sensor (30a), a capacitive-sensor (30b), a photoelectric-sensor (30c) or combinations thereof or can also use imaging-devices (not shown) to capture images or videos and analyze the image to identify liquid or solid. The ultrasonic-sensor (30a) transmits ultrasonic sound toward spoil (02), which reflects the sound back to the ultrasonic sensor (30a). The sound wave is well reflected by dense materials (metal, wood, plastic, glass, liquid, etc.) and is not affected by colour, transparent or shiny objects. The capacitive-sensor (30b) is an electronic device that can detect solid or liquid targets without physical contact. To categorize spoil (02), the capacitive-sensor (30b) emits an electrical field from the sensing end of the sensor. The photoelectric-sensor (30c) can effectively detect both liquids and solids by using light reflection. Although, the present disclosure discloses the ultrasonic sensor (30a), the capacitive-sensor (30b), the photoelectric-sensor (30c), however the present disclosure includes other sensors that have capability to detect solid, liquid or both solid and liquid of spoil (02) and can also use imaging devices and processors as known in the art which are programmed to read the digital images and videos to detect liquids and solids.

[013] The control-unit (40) is defined to receive sensed-parameters from the sensor-unit (30). The control-unit (40) is defined to categorize spoil (02) in solid-spoil (02a) and liquid-spoil (02b) based on the sensed-parameters received from the sensor-unit (30). The control-unit (40) determines solid-spoil (02a) in event when sensed-parameters of the sensor-unit (30) are less than prefed parameters defined in the control-unit (40). The control-unit (40) determines liquid-spoil (02b) in event when sensed-parameters of the sensor-unit (30) are more than prefed parameters defined in the control-unit (40). The prefed parameters can be determined based on the type of sensors to be used and as known in the art. Based on the category of spoil (02), the control-unit (40) operates the solid-spoil-indicator (50a) in event when solid-spoil (02a) is detected and operates the liquid-spoil-indicator (50b) in event when liquid-spoil (02b) is detected.

[014] The solid-spoil-indicator (50a) and the liquid-spoil-indicator (50b) are disposed in the cabin (05b) of the vehicle (05). The control-unit (40) operates the solid-spoil-indicator (50a) in event when spoil (02) is categorized as solid-spoil (02a), the control-unit (40) operates the liquid-spoil-indicator (50b) in event when spoil (02) is categorized as liquid-spoil (02b). Though the present disclosure discloses the solid-spoil-indicator (50a) and liquid-spoil-indicator (50b) disposed in the cabin (05b), however, the present invention is not limited to disposing the spoil-indicator (50a) and liquid-spoil-indicator (50b) in the cabin (05b) and can be disposed on other parts of the vehicle (05) or can be notified on a communication device (not shown) of the user (01).

[015] The solid-spoil-actuator (60a) is manually operated by a user (01) upon indication on the solid-spoil-indicator (50a) and the liquid-spoil-actuator (60b) is manually operated by the user (01) upon indication on the liquid-spoil-indicator (50b). The manual operation provides choice of selection to the user (01) to select the solid-spoil-actuator (60a) when the solid-spoil-indicator (50a) is indicated or select the liquid-spoil-actuator (50b). Similarly, the manual operation provides choice of selection to the user (01) to select the liquid-spoil-actuator (60b) when the liquid-spoil-indicator (50b) is indicated or select the solid-spoil-actuator (50a). Hence, the manual operation of the solid-spoil-actuator (60a) and the liquid-spoil-actuator (60b) provides operational choice to the user (01).

[017] The exhaust-unit (80) is connected to the suction-unit (70) and defined to exhaust the suctioned solid-spoil (02a) and the suctioned liquid-spoil (02b).

[018] The pipe-assembly (90) is defined with a first-branch-pipe (90a), a second-branch-pipe (90b) and a suction-pipe (90c). The suction-pipe (90c) is connected to the first-branch-pipe (90a) and the second-branch-pipe (90b) to establish connection with the suction-unit (90c). More specifically, the first-branch-pipe (90a), a second-branch-pipe (90b) and a suction-pipe (90c) enables connection of the solid-spoil suction-unit (91) and the liquid-spoil suction-unit (92).

[019] The solid-spoil suction-unit (91) is defined with a solid-check-valve (91a), a dust-filtration-tank (91b), a solid-shut-off-valve (91c). The solid-check-valve (91a) is defined on the first-branch-pipe (90a). The dust-filtration-tank (91b) is defined with a filter-unit (91bi). The dust-filtration-tank (91b) is in-connection with the first-branch-pipe (90a). The solid-shut-off-valve (91c) is functionally-connected with the vessel (10).

[020] The liquid-spoil suction-unit (92) is defined with a liquid-secondary-shut-off-valve (92a) and a liquid-primary-shut-off-valve (92b). The liquid-secondary-shut-off-valve (92a) is defined on the second-branch-pipe (90b). The liquid-primary-shut-off-valve (92b) is disposed on the vessel (10). In one embodiment, a vacuum-relief-valve (92c), a pressure-relief-valve (92d) and a butterfly-valve (92e) are disposed between the liquid-secondary-shut-off-valve (92a) and the liquid-primary-shut-off-valve (92b).

The vessel (10) is defined with a dust-removal conduit (10c) connected to the dust-filtration-tank (91b) through a tank-gate-valve (10d) and the vessel (10) through a vessel-gate-valve (10e).

[022] The present disclosure also discloses a method for spoil categorization and suction handling. The method, herein disclosed is the best method, for spoil categorization and suction handling, particularly suited for use in the vehicle-based spoil categorizing and suction handling system (100). The method enables the efficient and accurate handling of spoil materials—such as solid spoil (e.g., dust, debris) and liquid spoil (e.g., water, sludge)—by categorizing the spoil type at the point of suction and guiding the user (01)/operator to configure the system (100) for the appropriate suction mode. The method mitigates the risk of equipment damage due to improper mode selection and enhances operational versatility in diverse spoil removal applications. The following description details the steps of the method as claimed, with reference to the system components and their interactions.

[023] The method initiates with providing the vehicle-based spoil categorizing and suction handling system (100). The method begins with providing a vehicle-based spoil categorizing and suction handling system (100), which is installed on a vehicle (05), such as a suction excavator or vacuum truck, designed to remove spoil from a ground surface (03). The system (100), as disclosed in detailed in the above paragraphs, comprises several integrated components, each contributing to the method’s functionality:
-Vessel (10): A vessel (10) is mounted on the chassis (05a) of the vehicle (05) and serves as a storage container for suctioned spoil. The vessel includes the suction-conduit (10a) for material intake, the drain-conduit (10b) for liquid discharge, the dust-removal conduit (10c) for solid spoil removal, the tank-gate-valve (10d) connecting to the dust filtration tank, and the vessel-gate-valve (10e) for controlling material flow.
-Suction-Hose (20): The suction-hose (20) is provided, which includes the vessel-portion (20a) functionally connected to the vessel (10) and the suction-portion (20b) that is portable and can be positioned near the spoil (02) on the ground (03). The suction-hose (20) serves as the primary conduit for drawing spoil into the system (100).
-Sensor-Unit (30): The sensor-unit (30) is disposed on the suction-portion (20b) of the suction-hose (20). The sensor-unit includes one or more sensors, such as the ultrasonic-sensor (30a), the capacitive-sensor (30b), the photoelectric-sensor (30c), or combinations thereof, capable of detecting physical characteristics of the spoil.
-Control-Unit (40): The control-unit (40), typically an electronic control unit (ECU) or programmable logic controller (PLC), is in communication with the sensor-unit (30). The control-unit (40) processes sensor data and controls system operations based on predefined logic.
-Indicators (50a, 50b): The solid-spoil-indicator (50a) and the liquid-spoil-indicator (50b) are located in the vehicle’s cabin (05b), providing visual and/or audible signals to the user/operator (01) to indicate the categorized spoil type.
-Actuators (60a, 60b): The solid-spoil-actuator (60a) and the liquid-spoil-actuator (60b), such as manual switches or knobs, are provided for the operator to select the appropriate suction mode based on the indicator signals.
-Suction-Unit (70): The suction-unit (70) is positioned near the vessel (10) and generates the vacuum required for spoil suction. The suction-unit includes the suction-device (70a) (e.g., a centrifugal fan or pump), the check-valve (70b) to regulate flow, and a filter (70c) to protect the suction-device (70a).
-Exhaust-Unit (80): The exhaust-unit (80) is connected to the suction-unit (70) to release air or gases displaced during suction, ensuring system pressure balance.
-Pipe-Assembly (90): The pipe-assembly (90) comprises the first-branch-pipe (90a) for solid spoil, the second-branch-pipe (90b) for liquid spoil, and the suction-pipe (90c) connecting both branch pipes to the suction-unit (70), forming the bifurcated suction path.
-Solid-Spoil Suction-Unit (91): The solid-spoil suction-unit (91) includes the solid-check-valve (91a) on the first-branch-pipe (90a) to control flow, the dust-filtration-tank (91b) with the filter-unit (91bi) to capture fine particles, and the solid-shut-off-valve (91c) connected to the vessel (10) to regulate solid spoil intake.
-Liquid-Spoil Suction-Unit (92): The liquid-spoil suction-unit (92) includes the liquid-secondary-shut-off-valve (92a) on the second-branch-pipe (90b), the liquid-primary-shut-off-valve (92b) on the vessel (10), the vacuum-relief-valve (92c), the pressure-relief-valve (92d), and the butterfly-valve (92e) at respective inlets to manage liquid flow and system pressure.
-The system (100) configuration provides the foundation for the subsequent steps of the method, enabling precise spoil categorization and handling.

[024] The next step is porting the suction-portion (20b) of the suction-hose (20): The method involves porting the suction-portion (20b) of the suction-hose (20) to the vicinity of the spoil (02) on the ground (03). The operator (01) manually positions the suction-portion, which is typically a flexible or maneuverable end of the hose, close to the spoil to be removed. This step ensures that the sensor-unit (30) on the suction-portion is optimally placed to detect the spoil’s characteristics before suction begins.

[025] The next step is sensing spoil parameter by the sensor-unit (30). The sensor-unit (30) senses the spoil (02) to obtain sensed-parameters indicative of its physical properties. The sensor-unit may employ:
-The ultrasonic-sensor (30a) to measure sound frequency reflections, where solid spoil typically produces lower frequencies than liquid spoil due to differences in density and reflectivity.
-The capacitive-sensor (30b) to detect dielectric constants, where liquid spoil (e.g., water) exhibits a higher dielectric constant than solid spoil (e.g., dry debris).
-The photoelectric-sensor (30c) to detect light reflection or obstruction patterns, distinguishing solid and liquid spoil based on opacity or surface characteristics.
-Combinations of these sensors may be used to enhance accuracy. The sensed-parameters are transmitted electronically to the control-unit (40) for processing.

[026] The next step is receiving sensed-parameters. The control-unit (40) receives the sensed-parameters from the sensor-unit (30) via a wired or wireless communication link, such as a wiring harness or telemetry system. The control-unit (40) is programmed to interpret these parameters in real-time, preparing to categorize the spoil based on predefined criteria.

[027] The next step is categorizing spoil. The control-unit (40) categorizes the spoil (02) as either solid-spoil (02a) or liquid-spoil (02b) by comparing the sensed-parameters to prefed parameters stored in its memory:
-Solid-Spoil (02a): The spoil is categorized as solid-spoil if the sensed-parameters (e.g., dielectric constant, sound frequency, or light reflection) are less than the prefed thresholds. For example, a low dielectric constant or specific ultrasonic reflection pattern indicates dry materials like dust or gravel.
-Liquid-Spoil (02b): The spoil is categorized as liquid-spoil if the sensed-parameters exceed the prefed thresholds, such as a high dielectric constant typical of water or sludge.
[028] This categorization leverages the control-unit’s programmed logic, which may include threshold-based comparisons or algorithms to ensure reliable differentiation between spoil types.

[029] The next step is actuating indicators (50a, 50b). Based on the categorization:
-If the spoil is categorized as solid-spoil (02a), the control-unit (40) actuates the solid-spoil-indicator (50a) in the vehicle’s cabin (05b). The indicator may display a visual signal (e.g., a green light or text on a dashboard screen) and/or an audible alert (e.g., a beep or voice prompt) to inform the operator (01) of the presence of solid spoil.
-If the spoil is categorized as liquid-spoil (02b), the control-unit (40) actuates the liquid-spoil-indicator (50b), providing a distinct visual and/or audible signal to indicate liquid spoil.
-These indicators guide the user/operator (01) to select the appropriate suction mode, reducing the likelihood of erroneous configuration.

[030] The next step is manual operation of actuators. The operator (01) manually operates the appropriate actuator based on the indicator signals:
-Solid-Spoil-Actuator (60a): If the solid-spoil-indicator (50a) is actuated, the operator engages the solid-spoil-actuator (60a), typically a switch or knob labeled for solid spoil mode. This action signals the control-unit (40) to configure the system for solid spoil suction.
-Liquid-Spoil-Actuator (60b): If the liquid-spoil-indicator (50b) is actuated, the operator engages the liquid-spoil-actuator (60b), initiating liquid spoil mode.
-The manual operation ensures the operator retains control while being guided by the system’s automated categorization, balancing automation with human oversight.

[031] The next step is initiating suction for solid spoil. Upon operation of the solid-spoil-actuator (60a), the control-unit (40) signals the operation of the solid-spoil suction-unit (91). The sequence is as follows:
-The control-unit (40) opens the solid-shut-off-valve (91c), which is functionally connected to the vessel (10), allowing material flow.
-The suction-unit (70) is activated, with the suction-device (70a) generating a vacuum, regulated by the check-valve (70b) and protected by the filter (70c).
-Solid spoil (02a) is drawn through the suction-hose (20), entering via the suction-portion (20b) and vessel-portion (20a).
-The spoil follows a path through the vessel (10), the solid-shut-off-valve (91c), the dust-filtration-tank (91b) (where the filter-unit (91bi) captures fine particles), the solid-check-valve (91a), the first-branch-pipe (90a), the suction-pipe (90c), and the suction-unit (70).
-Air and residual gases are exhausted through the exhaust-unit (80), completing the suction cycle.
-The dust-filtration-tank (91b) ensures that fine solid particles are filtered, protecting downstream components. Solid spoil may be removed from the system via the dust-removal conduit (10c), controlled by the tank-gate-valve (10d) and vessel-gate-valve (10e), as needed.

[032] Initiating suction step for liquid spoil. Upon operation of the liquid-spoil-actuator (60b), the control-unit (40) signals the operation of the liquid-spoil suction-unit (92). The sequence is as follows:
-The control-unit (40) opens both the liquid-primary-shut-off-valve (92b) on the vessel (10) and the liquid-secondary-shut-off-valve (92a) on the second-branch-pipe (90b).
-The suction-unit (70) is activated, generating a vacuum through the suction-device (70a).
-Liquid spoil (02b) is drawn through the suction-hose (20), entering via the suction-portion (20b) and the vessel-portion (20a).
-The spoil follows a path through the vessel (10), the liquid-primary-shut-off-valve (92b), the liquid-secondary-shut-off-valve (92a), the second-branch-pipe (90b), suction-pipe (90c), and the suction-unit (70).
-Air and residual gases are exhausted through the exhaust-unit (80).
-The liquid suction path includes additional valves—the vacuum-relief-valve (92c), the pressure-relief-valve (92d), and the butterfly-valve (92e)—positioned at the inlets of the liquid-secondary-shut-off-valve (92a) to regulate pressure and prevent over-pressurization, ensuring safe liquid handling.

[033] The method supports versatility through its use of multiple sensor types, allowing for robust spoil detection under varying conditions. and enhances dielectric-based detection for improved accuracy. The system’s (100) design, with separate suction paths for solid and liquid spoil, prevents cross-contamination and component damage, addressing the disclosure’s concern about operator misuse. The vessel’s conduits (10a, 10b, 10c) and valves (10d, 10e) facilitate efficient material management, including drainage of liquids and removal of filtered solids.

[034] The method provides a systematic approach to spoil handling, integrating automated categorization with user-guided actuation to achieve reliable, damage-free suction of diverse spoil types within a single vehicle system.

[035] The advantages of the vehicle-based spoil categorizing and suction handling system (100) and method for spoil categorization and suction handling are
-Retains the core benefit of automatic spoil categorization, emphasizing reduced errors and equipment protection, as highlighted in the disclosure’s concern about user/operator (01) misuse.
-Sensor providing guidance: sensing and indicator steps, underscoring improved accuracy and user (01)/operator support, consistent with the disclosure’s focus on sensor data and dashboard indicators.
-Distinct Suction Paths: Corresponds to the solid-spoil suction-unit (91) and liquid-spoil suction-unit (92), preventing damage to components like filtration systems.
-Manual Actuators: the user/operator’s manually operates the actuators 60a, 60b, balancing automation of categorizing spoil (02) with manual control of initiating suction based on categorized spoil (02).
-Cost saving by using a single vehicle for categorizing and suction of liquid-spoil (02b) and solid-spoil (01), highlighting cost savings.
