Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a self-propelled inter-row weeding device for tall crops. Background Technology

[0002] Weeds in farmland have always been a significant factor affecting crop production. They compete with crops for sunlight, water, and fertilizer, as well as for growing space. Furthermore, the presence of weeds is also a contributing factor to diseases and pests, as they can serve as hosts for these pests, thereby harming crop yield and quality. Therefore, a significant amount of manpower and resources must be invested each year in the prevention and removal of weeds.

[0003] Currently, the main weeding methods include manual weeding, chemical weeding, and mechanical weeding. Compared to other methods, manual weeding is time-consuming, inefficient, and costly. Chemical weeding can effectively remove weeds from the field, but long-term use of chemical herbicides can damage and pollute the field environment, affecting the health of agricultural products. Biological weeding can reduce environmental pollution, but it has certain limitations. Thermal weeding is technically demanding and costly. Therefore, mechanical weeding has advantages such as high efficiency, low labor intensity, and no damage to the field environment. Weeds exist both between rows and between plants in the field. Traditional mechanical weeding equipment cannot remove weeds between crop plants at the same time. Therefore, a cross-row self-propelled intelligent and efficient weeding robot is needed, which can remove weeds between rows and between plants in the field simultaneously.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing weeding equipment has a basically fixed working width during operation, failing to flexibly adjust according to different crop spacing. When the spacing is narrow, it easily jams crop stems; when the spacing is wide, it misses weeds between plants, limiting its applicability to various plots. During operation, the moving parts easily collide with crop stems, especially when the crops are still seedlings, as the stems are thin and brittle, easily scratching the surface or damaging the internal transport tissues, potentially increasing the risk of disease later. Furthermore, weeding is not thorough enough. Most existing equipment only requires one shovelful, leaving weeds either intact in the soil where they easily regrow, or the stems are not broken and cannot be buried as fertilizer, resulting in poor weeding effectiveness. The height adjustment components of existing equipment are generally not flexible; when crops are seedlings, the shovel easily digs too deep, damaging the roots; when crops grow to maturity, it cannot reach higher weeds, requiring either equipment replacement or manual adjustment, significantly impacting work efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing self-propelled intercropping weeding equipment for tall crops has the disadvantage of poor weeding effect and flexibility. Therefore, we propose a self-propelled intercropping weeding equipment for tall crops.

[0016] The technical effects and advantages of this invention are as follows: In this invention, an adjustment structure using a bidirectional motor-driven screw and sleeve allows for flexible adjustment of the operating range based on the spacing between different tall crops, improving the equipment's adaptability to varying planting distances. A protective component connected to an arc-shaped airbag via a telescopic rod ensures flexible contact between the working parts and crop stems during movement, preventing hard contact and enhancing the safety of crops, especially seedlings. A structure that coordinates the height and spacing of the blade with the camera at the top of the main body, enabling real-time identification of weed locations and precise adjustment of operating parameters, improves the accuracy of weeding between plants. A rotating rod drives the flower rack and cutter... The secondary processing structure, combined with the blades, effectively breaks up residual weed stems and cuts off weed residue, improving the thoroughness of weed control and facilitating the return of chopped weeds to the field. The flexible adjustment structure of the support frame one and two, along with the lifting mechanism, adapts to different plant heights from seedling to mature stages, enhancing the equipment's applicability throughout the entire crop growth cycle. The structure, through the combination of cylinders and the lifting mechanism, adjusts the height of the shovel blade to suit soil hardness and weed root depth, improving root protection during weeding. Ultimately, this significantly improves the overall efficiency and safety of weeding between tall crops. Attached Figure Description

The working range of the subsequent components can be flexibly adjusted according to the spacing between plants, avoiding the inability of the components to adapt to crops with different plant spacings due to fixed positions.

[0022] A motor 562 is provided at the top of the long shell 561, and a gear 563 is provided at the output end of the motor 562. The gear 563 meshes with the rack 564, so that the expansion component 56 can cover weeds in different areas between plants and avoid the problem of weeds being missed due to the fixed position of the component.

[0023] A telescopic rod 551 is provided on one side of the extension frame 57, and the telescopic rod 551 is connected to the airbag 552.

[0024] A sleeve block 73 is rotatably connected to the outer side of the long rod 522. The sleeve block 73 is rotatably connected to the rotating rod 74. A bevel gear 71 is provided on the outer side of the long rod 522, and a bevel gear 72 is provided on the outer side of the rotating rod 74.

[0026] The bottom of the main body 1 of the equipment is provided with a connecting shell 81. The bevel gear set includes a bevel gear 3 82 located on the outside of the rotating rod 74 and a bevel gear 4 83 located on the outside of the rotating column 84. The bevel gear 3 82 and the bevel gear 4 83 are meshed and connected. The rotating rod 74 and the rotating column 84 are rotatably connected to the connecting shell 81. The bottom of the main body 1 of the equipment is provided with an outer shell 811, which is rotatably connected to the rotating column 84. The stems are broken by the rotation of the flower rack 75, which destroys the growth structure of weeds and prevents weed regeneration.

[0027] The reciprocating assembly includes a disc 85 disposed at one end of a rotating column 84. The surface of the disc 85 is provided with protrusions 86. The interior of the outer shell 811 is provided with a hollow block 89. A push plate 88 is slidably connected inside the hollow block 89. A frame plate 87 is disposed at one end of the push plate 88. The frame plate 87 is slidably connected to the protrusions 86. The push plate 88 is connected to a cutter 810, which drives the cutter 810 at its bottom end to cut the removed weeds into small sections.

[0028] Working principle: The device is driven by the external remote control to move the walking wheels 3 at the bottom of the main body 1 to the position between the tall crops at the edge of the field. Then, the device is driven by the remote control to enter the continuous self-moving mode, and the cylinder 41 is driven at the same time. The cylinder 41 drives the frame plate 42 at its output end to move down to the appropriate position, and the lifting component 43 is driven at the same time. The lifting component 43 drives the blade 45 fixed on the support frame 44 on one side to move down to the appropriate position. The four cameras 2 at the top of the main body 1 identify the weeds between the tall crops. Based on the identification results, the cylinder 41 and the lifting component 43 drive the blade 45 fixed on the support frame 44 to be fine-tuned to the optimal working position. This realizes remote control and positioning of the equipment. The camera 2 identifies the position of weeds in advance, and the height of the blade 45 can be adjusted accordingly to avoid the blade 45 being too high to miss weeds or too low to damage the crop roots, laying the foundation for efficient weeding in the future. The lifting component 43 can be any drive assembly with lifting function. In this solution, the lifting component 43 drives the output shaft screw to be threadedly connected to the outer linkage block through the drive source, and the linkage block is slidably connected to the vertical rods on both sides. By moving the linkage block up and down, the blade 45 at one end of the lifting component 43 can be moved to a different position. The lifting component 43 can also be replaced with other mechanical components with the same lifting effect. This part is not the core innovation point, so it will not be described in detail. The general lifting principle of the lifting component 43 is clear. Its structure can be flexibly replaced, reducing the cost of equipment component procurement and maintenance, while ensuring the stability of the lifting adjustment of the blade 45, and ensuring the basic weeding needs in different scenarios. While adjusting the position of the blade 45, the bidirectional motor 51 fixed at the bottom of the main body 1 is driven synchronously. The bidirectional motor 51 drives the screws 521 on both sides to rotate. The screws 521 are threadedly connected to the outer sleeves 523, and the sleeves 523 are slidably connected to the long rods 522 on both sides. The sleeves 523 are connected to the connecting plate 53 through the connecting block 524 at one end. As the screws 521 rotate, the two sets of sleeves 523 drive the connecting blocks 524 at each end to move in opposite directions, thereby driving the connecting plate 53 to achieve bidirectional position adjustment. This allows the bidirectional movement of the connecting plate 53, which can flexibly adjust the working range of subsequent components according to the spacing between plants, avoiding the inability of components to adapt to crops with different plant spacing due to fixed positions, and improving the adaptability of the equipment to different planting scenarios. A frame block 548 is provided on one side of the adjusting component 54. As the sleeve 523 drives the connecting plate 53 to move, the connecting plate 53 is rotatably connected to the rotating shaft 543, and the connecting plate 53 is connected to the frame block 548. When the connecting plate 53 moves, it drives the rotating shaft 543 to move synchronously. The rotating shaft 543 drives the gear 542 to move and meshes with the rack 541. At the same time, the rotating shaft 543 drives the turntable 544 to rotate. The turntable 544 drives the circular block 545 on its surface to rotate. The circular block 545 is slidably connected to the hollow plate 546, thereby driving the hollow plate 546 to rotate. The movable plate 547 on one side of plate 546 reciprocates; the movable plate 547 is slidably connected to the frame block 548. When the movable plate 547 reciprocates, it drives the extension frame 57 to reciprocate synchronously. The extension frame 57 then drives the expansion component 56 on one side to reciprocate, converting the linear movement of the connecting plate 53 into the reciprocating movement of the extension frame 57. This allows the expansion component 56 to flexibly adjust its lateral position, enabling it to cover weeds in different areas between plants, avoiding the problem of missed weeds due to fixed component positions, and improving the comprehensiveness of weed control between plants. A telescopic rod 551 is installed on one side of the extension frame 57, and an airbag 552 is installed on one side of the telescopic rod 551. The airbag 552 is arc-shaped. During the reciprocating movement of the extension frame 57 and the expansion component 56, the arc-shaped airbag 552 can fit against the surface of the stem of the tall crop to protect it. At the same time, the telescopic rod 551 can be flexibly adjusted in length according to the crop height and growth status to ensure that the airbag 552 is always in a protective position that matches the crop stem, avoiding collisions between the expansion component 56 or other operating parts and the crop during movement. The protection process does not affect the reciprocating movement and weeding operation of the expansion component 56. While ensuring crop safety, the weeding efficiency of the equipment is not reduced, further reducing the seedling damage rate and ensuring the quality and yield of crop growth in the later stage. After the camera 2 at the top of the main body 1 identifies the specific location of the weeds, the position of the long shell 561 in the extension component 56 is adjusted to move it to the area where the weeds are concentrated. Then, the motor 562 on one side of the long shell 561 is started simultaneously. The motor 562 drives the gear 563 on the output shaft to rotate. Since two sets of symmetrically distributed racks 564 are slidably connected inside the long shell 561, the gear 563 meshes with the two sets of racks 564. When rotating, it drives the two sets of racks 564 to move in opposite directions. The two sets of racks 564 drive the driven plates 565 on each side to move in opposite directions. Both sets of driven plates 565 are slidably connected to the long shell 561, thereby driving each The frame plate 261 on one side moves; inside the frame plate 261, a support frame 263 is connected through a lifting component 262. A shovel 264 is set at the bottom of the support frame 263. The lifting component 262 has the same lifting principle as the lifting component 143 mentioned above. Through the drive of the lifting component 262, the distance between the two sets of shovels 264 can be flexibly adjusted. Combined with the weed positioning function of the camera 2, the distance between the shovels 264 can be adjusted through the meshing transmission of gear 2563 and rack 2564. This can adapt to crops with different plant spacing and weeds with different distribution densities, avoid the shovels 264 being too narrow to jam crops or too wide to miss weeds, and further improve the accuracy of weeding between plants. As the screw 521 in the moving component 52 rotates, the outer bevel gear 71 meshes with the bevel gear 72, and the bevel gear 72 drives the sleeve block 73 on one side to rotate. The sleeve block 73 is fixedly connected to the main body 1 of the equipment. The top of the sleeve block 73 is rotatably connected to the rotating rod 74, and the rotating rod 74 is rotatably connected to the screw 521. A flower rack 75 is provided at the bottom of the rotating rod 74. When the flower rack 75 rotates with the rotating rod 74, it can break the stems of weeds that have not been completely removed by the shovel blade 45 and the shovel blade 64, and perform secondary treatment on the stems of weeds left over from the first weeding. By rotating the flower rack 75 to break the stems, the growth structure of weeds is destroyed, preventing weed regeneration. At the same time, the stems are prevented from blocking the crop's sunlight, thus improving the thoroughness of weeding and the quality of the crop's growth environment. As the rotating rod 74 rotates, the outer bevel gear 82 rotates synchronously. The bevel gear 82 meshes with the bevel gears 83 on both sides, and the two sets of bevel gears 83 drive the rotating column 84 on each side to rotate. Both sets of rotating columns 84 are rotatably connected to the connecting shell 81, and the rotating rod 74 is rotatably connected to the connecting shell 81. The connecting shell 81 is connected to the main body 1 of the equipment. The rotating column 84 drives the disc 85 on one side to rotate, and the disc 85 drives the protrusion 86 on its surface to rotate. The protrusion 86 is slidably connected to the frame plate 87, thereby driving the frame plate. The push plate 88 on one side of 87 moves up and down repeatedly; the push plate 88 is slidably connected to the hollow block 89, the hollow block 89 is connected to the outer shell 811, and the outer shell 811 is connected to the main body 1 of the equipment. When the push plate 88 moves up and down, it drives the cutter 810 at its bottom end to cut the weeds that have been removed, cutting the removed weeds into small sections. On the one hand, this facilitates the subsequent return of chopped grass to the field, increasing soil organic matter. On the other hand, it can reduce the possibility of secondary rooting of weeds due to the residue of whole plants, further consolidating the weeding effect, while avoiding the accumulation of weed residues that affect crop growth.

[0029] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
