[0045] The terms “having”, “comprising”, “including”, and variations thereof signify the presence of a component.
[0046] Referring now to FIG. 1 to FIG. 3 to describe various exemplary embodiments of the present disclosure. FIG. 1 illustrates a perspective view of a dual-depth multi-species intercrop seeding device and method thereof 100, in accordance with an exemplary embodiment of the present disclosure.
[0047] The main crop seed hopper 102 is forming a primary seed storage chamber of the dual-depth multi-species intercrop seeding device 100 and is storing medium-sized to large-sized agricultural seeds including direct-seeded rice, maize, cotton, soybean, pulses, oilseeds, and vegetable crop seeds. The main crop seed hopper 102 is being structurally mounted on a vibration-absorbing support arrangement connected to a supporting frame so that uniform gravitational seed flow is being maintained during operation over uneven agricultural fields. Internal agitator members positioned within the main crop seed hopper 102 are continuously disturbing accumulated seed mass to prevent bridging, clogging, or irregular discharge. Moisture-sealed cover elements enclosing an upper opening of the main crop seed hopper 102 are protecting stored seeds from atmospheric moisture, particulate contamination, and environmental exposure. Seed-level indicator mechanisms integrated with the main crop seed hopper 102 are enabling real-time visual monitoring of remaining seed volume during continuous sowing activity.
[0048] The first seed dispensing path 104 is extending between the main crop seed hopper 102 and the electronic seed metering unit 110 and is forming a physically independent conduit dedicated exclusively to main crop seed transfer. The first seed dispensing path 104 is maintaining uninterrupted seed flow from the main crop seed hopper 102 toward the electronic seed metering unit 110 while remaining structurally isolated from the second seed dispensing path 108 to prevent intermixing of seed categories. The first seed dispensing path 104 is directing main crop seeds into the electronic seed metering unit 110 for controlled regulation, synchronized metering based on forward movement of the dual-depth multi-species intercrop seeding device 100, and subsequent depth-specific placement through the deep coulter 112.
[0049] In one embodiment of the present disclosure, the main crop seed hopper 102 and the brown-manure crop hopper 106 are being fabricated from corrosion-resistant materials including mild steel, stainless steel, aluminum alloy, reinforced polymer composites, or high-density polyethylene, and internal surfaces are being coated with anti-static and low-friction linings to improve seed flow characteristics under high humidity field conditions.
[0050] In one embodiment of the present disclosure, the main crop seed hopper 102 and the brown-manure crop hopper 106 are incorporating interchangeable volumetric capacities ranging from small-capacity modules for vegetable cultivation to high-capacity bulk modules for large-scale cereal production, thereby enabling scalability across farm sizes.
[0051] In one embodiment of the present disclosure, the internal agitator mechanism within the main crop seed hopper 102 and the flow-regulation mechanism within the brown-manure crop hopper 106 are being mechanically driven by auxiliary shafts coupled to the electronic seed metering unit 110 or independently powered by electric actuators to ensure uninterrupted seed discharge.
[0052] The brown-manure crop hopper 106 is forming a secondary and independent seed storage chamber of the dual-depth multi-species intercrop seeding device 100 and is storing small-sized leguminous seeds including Sesbania, cowpea, sunhemp, and other brown-manure species intended for inter-row biomass generation. The brown-manure crop hopper 106 is being structurally mounted on the supporting frame in spatial separation from the main crop seed hopper 102 so that independent handling of distinct seed categories is being ensured. The brown-manure crop hopper 106 is incorporating an adjustable flow control gate configured to regulate fine seed discharge rate based on crop-specific requirements and seed size characteristics. The structural configuration of the brown-manure crop hopper 106 is preventing seed bridging and uncontrolled flow, thereby maintaining consistent gravitational feed toward electronic seed metering unit 110. The brown-manure crop hopper 106 is operating independently from the main crop seed hopper 102 so that metering parameters, dispensing rate, and seed type are being controlled without mutual interference.
[0053] The second seed dispensing path 108 is extending between the brown-manure crop hopper 106 and the electronic seed metering unit 110 and is forming a physically isolated conduit dedicated exclusively to brown-manure seed transfer. The second seed dispensing path 108 is maintaining uninterrupted and contamination-free movement of brown-manure crop seeds toward the electronic seed metering unit 110 while remaining structurally independent from the first seed dispensing path 104. The second seed dispensing path 108 is directing brown-manure crop seeds into the electronic seed metering unit 110 for differentiated regulation, synchronized dispensing, and subsequent shallow-depth, laterally offset placement through the shallow coulter 114.
[0054] The electronic seed metering unit 110 is forming a central regulation and control assembly of the dual-depth multi-species intercrop seeding device 100 and is being operatively connected to the main crop seed hopper 102 and the brown-manure crop hopper 106. The electronic seed metering unit 110 is receiving main crop seeds from the main crop seed hopper 102 through the first seed dispensing path 104 and is receiving brown-manure crop seeds from the brown-manure crop hopper 106 through the second seed dispensing path 108. The electronic seed metering unit 110 is performing differentiated regulation of two distinct seed categories and is directing regulated main crop seeds into the first seed dispensing path 104 toward the deep coulter 112 while simultaneously directing regulated brown-manure crop seeds into the second seed dispensing path 108 toward the shallow coulter 114. The electronic seed metering unit 110 is operating in synchronization with forward movement of the device 100 by continuously adjusting seed release rate according to ground speed input, thereby ensuring spatial accuracy of seed placement relative to travel distance. The electronic seed metering unit 110 is integrating electromechanical actuation and sensor-based feedback so that dual-species dispensing is occurring in a coordinated and non-interfering manner.
[0055] The first stepper motor-driven metering disc 120 is forming a primary metering mechanism within the electronic seed metering unit 110 and is being positioned to regulate dispensing of main crop seeds received from the main crop seed hopper 102. The first stepper motor-driven metering disc 120 is rotating in controlled increments determined by the microcontroller unit 124 and is enabling calibrated release of main crop seeds into the first seed dispensing path 104. The first stepper motor-driven metering disc 120 is ensuring that seed output corresponds to predefined seed rate parameters and is preventing over-dispensing or irregular seed distribution. The first stepper motor-driven metering disc 120 is being mechanically aligned with internal seed chambers so that uniform seed pickup and discharge is being maintained during continuous operation over variable terrain conditions.
[0056] The second stepper motor-driven metering disc 122 is forming an independent metering mechanism within the electronic seed metering unit 110 and is being dedicated to regulation of brown-manure crop seeds received from the brown-manure crop hopper 106. The second stepper motor-driven metering disc 122 is rotating under electronic control and is delivering calibrated quantities of small-sized leguminous seeds into the second seed dispensing path 108. The second stepper motor-driven metering disc 122 is being structurally and functionally independent from the first stepper motor-driven metering disc 120 so that distinct seed rate parameters for different crop species are being maintained simultaneously. The second stepper motor-driven metering disc 122 is enabling fine resolution dispensing suitable for small-seeded crops and is preventing clustering, excessive drop, or inconsistent seed spacing.
[0057] The microcontroller unit 124 is forming an electronic control core of the electronic seed metering unit 110 and is being electrically connected to the first stepper motor-driven metering disc 120 and the second stepper motor-driven metering disc 122. The microcontroller unit 124 is receiving ground speed data from the ground-wheel speed sensor 128 and is receiving seed-flow data from optical or vibration-based seed-flow sensors 126 positioned along the first seed dispensing path 104 and the second seed dispensing path 108. The microcontroller unit 124 is processing real-time input signals and is generating precise control pulses to regulate rotational movement of the first stepper motor-driven metering disc 120 and the second stepper motor-driven metering disc 122. The microcontroller unit 124 is continuously adjusting dispensing frequency in proportion to forward movement of the device 100 so that seed spacing along the soil surface is remaining uniform regardless of speed variations. The microcontroller unit 124 is coordinating simultaneous dual-species metering and is ensuring that depth-differentiated placement through the deep coulter 112 and the shallow coulter 114 is occurring without overlap or timing conflict.
[0058] The optical or vibration-based seed-flow sensors 126 are forming feedback detection elements within the electronic seed metering unit 110 and are being positioned along the first seed dispensing path 104 and the second seed dispensing path 108. The optical or vibration-based seed-flow sensors 126 are detecting movement of seeds passing through respective dispensing paths and are transmitting seed-flow status signals to the microcontroller unit 124.
