Description

Technical Field

[0001] This utility model relates to the field of weeding technology, specifically to an agricultural machinery weeding device. Background Technology

[0002] A lawnmower consists of a drive shaft that transmits the rotational driving force of a prime mover (such as an electric motor) to the blades via a connecting component. This causes the blades and the connecting component to rotate around the drive shaft, thereby cutting the grass on the ground.

[0003] A search revealed that patent application number CN202322038859.9 discloses an intelligent lawnmower. Although the device adjusts the cutting components in three dimensions by setting a second power source and a drive mechanism during use, it only focuses on adjusting the cutting components and does not design and optimize the weeding blade matching structure for different weed growth states and soil conditions. Therefore, it cannot efficiently cut weeds with shearing force. Furthermore, it lacks convenient overall height adjustment and agricultural machinery adaptation connection methods, making it difficult to adapt to complex and ever-changing farmland environments. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an agricultural machinery weeding device, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] An agricultural machinery weeding device includes a side plate, on which a blade roller is mounted;

[0007] A blade is installed on one side of the blade roller on the side plate. The blade and the blade roller cooperate with each other to cut weeds by shearing force. A pressure roller is installed on the side of the side plate opposite to the blade roller. A roller is rotatably installed on the side plate. A toothed ring is provided on the inner side of the roller. Gears are provided on both sides of the blade roller. When the roller rotates, it drives the blade roller to rotate by meshing the toothed ring with the gear.

[0008] A connecting rod is installed on the side plate, and a connecting frame is connected to the side plate through the connecting rod. A connecting rod is installed on the connecting frame through a limiting plate. A connecting plate is provided at one end of the connecting rod, and the connecting rod is connected and fixed to the agricultural machinery through the connecting plate.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, an intermediate gear is installed on the limiting plate between the connecting rod and the connecting frame. Key teeth are provided on the lower surface of the connecting rod and the outer surface of the connecting frame. When the connecting rod is pulled, the connecting rod meshes with the connecting frame through the intermediate gear, causing the cutting edge of the blade to deflect downward.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] This design incorporates a precise height-adjustable transmission mechanism. Through the meshing of a central gear and key teeth, the pulling of the connecting rod is converted into precise deflection of the blade edge. When encountering weeds of varying heights or uneven ground, the operator pulls the connecting rod, causing the blade edge to deflect downwards quickly and steadily. This allows for flexible adjustment of the weeding height, ensuring the weeding device always effectively contacts the weeds and maintains high-efficiency weeding results. Simultaneously, the meshing transmission of the gear and key teeth offers excellent stability and reliability, capable of withstanding heavy workloads, reducing component wear caused by frequent adjustments, and extending the device's lifespan.

[0013] Furthermore, the connecting rod has limit grooves on both sides, and the limit plate has protrusions. The connecting rod slides between the limit plate through the limit grooves and protrusions.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The cooperation between the limiting groove and the protrusion provides precise guidance and limiting function for the sliding of the connecting rod. When adjusting the height of the weeding device, the connecting rod can slide smoothly along the limiting groove, avoiding deviation or wobbling, and ensuring the accuracy and stability of the blade height adjustment. At the same time, this limiting structure can effectively limit the sliding range of the connecting rod, preventing excessive sliding that could cause damage to the device structure or malfunction, thus improving the safety and reliability of the device operation. In addition, this structure is simple and practical, easy to install and maintain, and reduces the maintenance cost of the equipment.

[0016] Furthermore, the blade plate is provided with a rotating shaft at both ends, and the blade plate is rotatably mounted on the side plate through the rotating shaft. An adjusting bolt is installed on the side plate, and the end of the adjusting bolt contacts the blade plate. The angle between the blade plate and the horizontal plane is adjusted by adjusting the adjusting bolt.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] This design provides flexibility in blade angle adjustment. By tightening the adjusting bolt, the angle between the blade and the horizontal plane can be precisely changed, thereby adjusting the shearing angle and force between the blade and the roller. When dealing with different types and growth stages of weeds, operators can flexibly adjust the blade angle according to the actual situation, optimizing the cooperation between the blade and the roller, allowing the shearing force to act more effectively on the weeds, improving weeding efficiency and quality. Furthermore, this adjustment method is simple to operate, requiring no complicated tools or professional skills, allowing operators to quickly adjust in the field to adapt to different working environments and needs.

[0019] Furthermore, the cutter roller is provided with helical blades.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The spiral blade design significantly improves the weeding performance of the weeding device. Compared to ordinary blades, the spiral blades, during the rotation of the blade roller, can contact the weeds in a spiral manner, increasing the contact area and contact time between the blade and the weeds, allowing the weeds to be cut more thoroughly. Simultaneously, the propulsive force generated by the spiral structure helps to concentrate the weeds towards the blades, improving cutting efficiency and success rate, and reducing missed weeds. Furthermore, the spiral blades generate a certain axial force when cutting weeds, helping to push the cut weeds to one side, preventing weeds from accumulating near the blade roller, ensuring the continuous and smooth operation of the weeding device, and reducing the risk of equipment failure due to weed blockage.

[0022] This utility model provides an agricultural machinery weeding device. It has the following beneficial effects:

[0023] The cutter roller is equipped with spiral blades that work in conjunction with the blade plate to cut weeds through shearing force, effectively removing weeds and improving weeding efficiency.

[0024] The blade is mounted on the side plate via a rotating shaft, and the side plate is equipped with adjusting bolts to adjust the angle between the blade and the horizontal plane. The blade angle can be flexibly adjusted according to different weed growth conditions and soil conditions to achieve the best weeding effect.

[0025] The roller has a toothed ring on its inner side and gears on both sides of the cutter roller. When the roller rotates, the cutter roller is driven to rotate through the meshing of the toothed ring and the gears. This transmission method is simple and reliable, can effectively transmit power, and ensure the normal operation of the cutter roller.

[0026] The connecting rod slides between the limiting plate via the limiting groove and the protrusion. An intermediate gear is installed on the limiting plate between the connecting rod and the connecting frame. When the connecting rod is pulled, the intermediate gear meshes with the connecting frame, causing the blade edge to deflect downwards. The working height of the weeding device can be easily adjusted according to the height of the weeds and the undulation of the soil, ensuring a uniform weeding effect.

[0027] One end of the connecting rod is equipped with a connecting plate, which is used to connect and fix the weeding device to the agricultural machinery, ensuring the stability of the connection between the weeding device and the agricultural machinery. This prevents the device from loosening during operation and ensures its stable operation. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0039] Example 1

[0040] An agricultural machinery weeding device includes a side plate 5, on which a cutter roller 9 is mounted. The cutter roller 9 has spiral blades, and the spiral blade design significantly improves the weeding performance of the device. Compared to ordinary blades, the spiral blades, during the rotation of the cutter roller 9, can contact the weeds in a spiral propulsion manner, increasing the contact area and contact time between the blades and the weeds, allowing the weeds to be cut more thoroughly. Simultaneously, the propulsive force generated by the spiral structure helps to concentrate the weeds towards the blades, improving the cutting efficiency and success rate, and reducing the occurrence of missed weeds. Furthermore, the spiral blades generate axial force when cutting weeds, helping to push the cut weeds to one side and preventing them from accumulating near the cutter roller 9. This ensures the continuous and smooth operation of the weeding device and reduces the risk of equipment failure due to weed blockage. A blade plate 7 is mounted on the side plate 5, located on one side of the cutter roller 9. The blade plate 7 has rotating shafts 702 at both ends, allowing it to rotatably mount on the side plate 5. Adjusting bolts 701 are installed on the side plate 5, with their ends contacting the blade plate 7. These bolts allow for adjustment of the angle between the blade plate 7 and the horizontal plane, providing flexibility in angle adjustment. By tightening the adjusting bolts 701, the angle between the blade plate 7 and the horizontal plane can be precisely changed, thereby adjusting the shearing angle and force between the blade plate 7 and the cutter roller 9. For different types and growth stages of weeds, operators can flexibly adjust the angle of the blade plate 7 according to the actual situation, optimizing the cooperation between the blade plate 7 and the cutter roller 9, allowing the shearing force to act more effectively on the weeds, and improving the efficiency and quality of weeding. In addition, this adjustment method is simple to operate, requiring no complicated tools or professional skills, making it convenient for operators to quickly adjust in the field to adapt to different working environments and needs. The blade 7 and the blade roller 9 work together to cut weeds through shearing force. A pressure roller 6 is installed on the side plate 5 on the side of the blade 7 away from the blade roller 9. A roller 4 is rotatably installed on the side plate 5. A toothed ring 401 is provided on the inner side of the roller 4. Gears 901 are provided on both sides of the blade roller 9. When the roller 4 rotates, it drives the blade roller 9 to rotate through the meshing of the toothed ring 401 with the gears 901.

[0041] Example 2

[0042] To enable the weeding device to flexibly adjust its working height according to different weed heights and ground conditions, thereby improving weeding efficiency and the device's applicability and reliability, for example, such as Figures 1 to 5As shown, this utility model also includes: a connecting rod 8 installed on the side plate 5; a connecting frame 3 connected to the side plate 5 via the connecting rod 8; a connecting rod 2 installed on the connecting frame 3 via a limiting plate 10; limiting grooves 201 are provided on both sides of the connecting rod 2; and protrusions are provided on the limiting plate 10. The connecting rod 2 slides between the limiting plate 10 via the limiting grooves 201 and the protrusions. The cooperation between the limiting grooves 201 and the protrusions provides precise guidance and limiting function for the sliding of the connecting rod 2. When adjusting the height of the weeding device, the connecting rod 2 can slide smoothly along the limiting grooves 201, avoiding deviation or shaking, and ensuring the accuracy and stability of the height adjustment of the blade 7. At the same time, this limiting structure can effectively limit the sliding range of the connecting rod 2, preventing excessive sliding that could cause damage to the device structure or malfunction, thus improving the safety and reliability of the device operation. Furthermore, this structure is simple and practical, easy to install and maintain, reducing equipment maintenance costs. An intermediate gear 11 is installed on the limiting plate 10 between the connecting rod 2 and the connecting frame 3. Key teeth are provided on the lower surface of the connecting rod 2 and the outer surface of the connecting frame 3. When the connecting rod 2 is pulled, it meshes with the connecting frame 3 through the intermediate gear 11, causing the blade edge of the blade 7 to deflect downwards. This design constructs a precise height adjustment transmission mechanism. Through the meshing transmission of the intermediate gear 11 and the key teeth, the pulling of the connecting rod 2 is converted into a precise deflection of the blade edge of the blade 7. When encountering weeds of different heights or uneven ground, the operator pulls the connecting rod 2, and the blade edge of the blade 7 can quickly and stably deflect downwards, achieving flexible adjustment of the weeding height and ensuring that the weeding device always effectively contacts the weeds, maintaining a highly efficient weeding effect. Meanwhile, the meshing transmission between gear 901 and key teeth has good stability and reliability, can withstand large working loads, reduce component wear caused by frequent adjustments, and extend the service life of the device. One end of the connecting rod 2 is provided with a connecting plate 1, and the connecting rod 2 is connected and fixed to the agricultural machinery through the connecting plate 1.

[0043] Working principle:

[0044] First, the connecting rod 2 of the weeding device is fixedly connected to the agricultural machinery through the connecting plate 1 to ensure that the device is securely installed on the agricultural machinery, providing a foundation for subsequent operations.

[0045] When the agricultural machinery is running, it drives the roller 4 to rotate, which pulls the connecting rod 2. At this time, the key teeth on the lower surface of the connecting rod 2 and the outer surface of the connecting frame 3 mesh with the intermediate gear 11, causing the blade 7 to deflect downward, changing the distance between the blade 7 and the ground, thereby adjusting the working height of the entire weeding device and ensuring that the weeding operation continues effectively.

[0046] The gear ring 401 on the inner side of the roller 4 meshes with the gears 901 on both sides of the cutter roller 9, transmitting the power of the agricultural machinery to the cutter roller 9, causing the cutter roller 9 to start rotating. The spiral blades on the cutter roller 9 then rotate, preparing for weeding.

[0047] As the agricultural machinery moves forward, the rotating cutter roller 9 and the blades 7 on the side plate 5 work together to cut the weeds using the shearing force generated by both, thus achieving the weeding function. The angle between the blades 7 and the horizontal plane can be changed by adjusting the bolt 701 to adapt to weeds of different growth stages and densities, thereby improving the weeding effect. At the same time, the pressure roller 6 compacts the cut weeds, facilitating subsequent cleaning or returning them to the field.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
