Description:FIELD OF DISCLOSURE
[0001] The present disclosure generally relates to agricultural weed management equipment, more specifically, relates to a dual-action ground-driven rolling inter-row weed crushing device.
BACKGROUND OF THE DISCLOSURE
[0002] Agriculture plays a critical role in food production, and effective weed management is essential for ensuring healthy crop growth and optimum yield. In row-planted crops such as maize, cotton, soybean, pulses, and vegetables, weeds commonly grow in the spaces between crop rows and compete with cultivated plants for nutrients, sunlight, moisture, and soil resources. If not controlled in a timely manner, weed infestation significantly reduces productivity and increases cultivation costs. Efficient inter-row weed management therefore remains a key requirement in modern agricultural practices.
[0003] Traditional weed control in row crops has carried out using manual implements such as hand hoes and wheel hoes, which require significant physical effort and repeated field passes. In larger farms, farmers often use mechanical implements such as rotary weeders, inter-row cultivators, star-wheel weeders, finger weeders, and tractor-mounted tillage attachments. These conventional devices generally function through continuous cutting, digging, uprooting, or soil-stirring actions to remove unwanted vegetation. While such methods may reduce manual labour to some extent, they tend to disturb the soil structure excessively, leading to moisture loss, soil compaction in certain conditions, and disruption of beneficial soil microorganisms. Continuous blade or tine engagement also increases frictional resistance, resulting in higher draft requirement and greater energy consumption. Furthermore, many of these traditional implements lack precise control within the inter-row space. Minor misalignment during operation exposes crop roots, injure stems, or uproot young plants, particularly in closely spaced crops. Power-operated weeders require fuel or motorized assistance, which may not be economically viable for small and marginal farmers. Even manually operated tools become inefficient in partially moist, compacted, or uneven field conditions. As a result, conventional weed management techniques often involve trade-offs between effectiveness, crop safety, operational cost, and soil health, leaving room for significant improvement in inter-row weed control technology.
[0004] The present invention addresses these limitations by introducing an improved agricultural implement capable of managing weeds in inter-row spaces in a more selective and energy-efficient manner, while minimizing soil disturbance and preventing crop injury. The present invention operates with reduced power requirement, offer precise action within the inter-row region, and provide effective weed suppression without uprooting or damaging cultivated plants. The development of such an improved mechanical arrangement would enhance crop safety, operational efficiency, and sustainability in weed management practices.

[0078] FIG. 2 illustrates a schematic 200 representation of a dual-action ground-driven rolling inter-row weed crushing device 100, in accordance with an embodiment of the present disclosure. The invention relates to a mechanically operated, ground-driven agricultural implement configured for selective weed suppression within inter-row spaces of line-sown and row-planted crops. The device 100 provides an energy-efficient, crop-safe, and low-maintenance solution without dependence on fuel engines. The device 100 comprises the rectangular frame 102 supporting the plurality of metal rollers 104 fabricated from mild steel for structural strength and durability under field conditions. Each roller typically ranges between 20 to 30 cm in length and 10 to 15 cm in diameter and is provided with the plurality of removable crushing plates 118 positioned intermittently around the outer surface. The rollers are mounted parallel within the rectangular frame 102 and are adjustable in spacing to accommodate crop row spacings such as 45 cm, 60 cm, and 90 cm while minimizing soil disturbance. A key feature of the invention is the incorporation of the ratchet-cam timing mechanism 106, which is operatively connected to the plurality of metal rollers 104 to enable intermittent activation of the plurality of removable crushing plates 118. A cam follower linkage actuates the plurality of removable crushing plates 118 at predetermined angular positions during roller rotation, ensuring controlled application of compressive force at specific intervals. This selective engagement reduces mechanical drag, conserves energy, and limits excessive soil disruption. When not activated, the plurality of removable crushing plates 118 remain in a non-engaged position to conserve mechanical motion and minimize clogging. The implement further incorporates the pre-tensioned helical spring regulates downward pressure, with adjustable tension to suit weed density and soil conditions. Rotational power is derived from the plurality of ground wheels 108, which transmit motion through the ground-driven gearbox 110 to drive the plurality of metal rollers 104 in synchronized counter rotation. The ground-driven gearbox 110 maintains functional roller speed under varying forward velocities during manual and tractor-assisted operation, eliminating the need for external power sources. To ensure precise alignment within the inter-row space, the implement includes the row-positioning guide 114 ensures accurate alignment between crop rows and prevents lateral drift during operation. The plurality of corrosion-resistant bearings 120 supports smooth rotation of the rollers and requires periodic lubrication. The plurality of removable crushing plates 118 allow economic maintenance and replacement. During operation, forward movement of the implement drives the plurality of ground wheels 108, the ground-driven gearbox 110, and the plurality of metal rollers 104. The intermittently activated plurality of removable crushing plates 118 apply compressive force from both sides of weed stems, flattening weeds against the soil surface without uprooting crops. The device 100 operates effectively under dry, moist, and lightly compacted soil conditions. By integrating intermittent engagement, controlled pressure regulation, synchronized counter rotation, precise row alignment, and fully ground-driven mechanical operation, the invention provides an efficient, sustainable, and cost-effective solution for inter-row weed management.
[0079] FIG. 3 illustrates a flow chart of a method 300, outlining the sequential steps for the dual-action ground-driven rolling inter-row weed crushing device 100, in accordance with an embodiment of the present disclosure.
[0080] At step 202, the device 100 is positioned within an inter-row space between adjacent crop rows using the row-positioning guide 114.
[0081] At step 204, the device 100 is moved forward to rotate the plurality of ground wheels 108 through soil contact.
[0082] At step 206, the rotational motion is transmitted from the plurality of ground wheels 108 to the ground-driven gearbox 110.
[0083] At step 208, the plurality of metal rollers 104 is drive in synchronized counter rotation via the ground-driven gearbox 110.
[0084] At step 210, the plurality of removable crushing plates 118 is actuated using the ratchet-cam mechanism 106.
[0085] At step 212, the controlled downward pressure is applied through the pressure regulator 112.
[0086] At step 214, the inter-row weeds are crushed by dual-sided compression to flatten the weeds without damaging crop plants.
[0087] In the best mode of operation of the present invention, the device 100 is positioned within the inter-row space between adjacent cultivated crop rows. The row-positioning guide 114 assists in maintaining proper alignment to ensure that the device 100 remains cantered between crop rows and avoids contact with standing crop stems. The device 100 is then manually pushed using the handle 116 and may alternatively be pulled by a small tractor during field operation. As the device 100 advances forward, the plurality of ground wheels 108 rotate due to contact with the soil surface. These ground wheels serve as the sole power source for the device 100, eliminating the need for fuel, electrical input, and external drive units. The rotational motion generated by the plurality of ground wheels 108 is transmitted to the ground-driven gearbox 110. The ground-driven gearbox 110 converts and regulates this motion, delivering synchronized counter rotation to the plurality of metal rollers 104. The ground-driven gearbox 110 ensures appropriate torque and rotational speed regardless of variations in forward movement. As the plurality of metal rollers 104 rotate, the ratchet–cam timing mechanism 106 intermittently activates the plurality of removable crushing plates 118 mounted on the rollers. This mechanism ensures that crushing force is applied at predetermined angular intervals rather than continuously. The intermittent engagement reduces mechanical resistance, conserves energy, and prevents excessive soil disturbance. Simultaneously, the pressure regulator 112, preferably comprising a pre-tensioned helical spring, controls the downward force applied by the rollers and crushing plates. The spring tension is adjustable according to weed density, stem thickness, and soil conditions to ensure effective weed compression without soil compaction and crop root damage. During operation, the synchronized counter-rotating rollers apply compressive force from both sides of the weed stems. This dual-action crushing flattens weeds against the soil surface rather than uprooting them. The flattened weeds subsequently undergo natural decomposition, contributing organic matter to the soil. The plurality of corrosion-resistant bearings 120 support smooth rotational movement of the plurality of metal rollers 104, while the plurality of shafts 122 and the plurality of fasteners 124 maintain structural stability and alignment of rotating components. The protective safety shield 126 encloses the plurality of metal rollers 104 to prevent operator contact and reduce debris dispersion. Through this coordinated mechanical workflow, the device 100 converts simple forward movement into controlled, intermittent, dual-sided weed crushing. The device 100 operates efficiently under dry, moist, and lightly compacted soil conditions, providing a sustainable, low-maintenance, and energy-independent solution for inter-row weed management.
