Description

Technical Field

[0001] This utility model relates to the field of weeding technology, specifically to a weeding device for inter-row planting in forestry and grassland. Background Technology

[0002] Forestry and grassland planting often employs a regular row planting or transplanting pattern. Trees in plantations, herbaceous crops in pasture bases, and vegetation for slope greening are all planted in parallel rows according to a set pattern, with specific spacing between rows. This spacing not only ensures the ventilation and light conditions necessary for the growth of forestry and grassland but also provides operational space for later management operations such as irrigation, fertilization, and weeding. The inter-row weeding device for forestry and grassland planting is specifically designed for the "gap area between adjacent rows of forestry and grassland" in this planting pattern. It can precisely match the row spacing specifications of different forestry and grassland planting methods, clearing only weeds between rows during operation. This effectively prevents weeds from competing with forestry and grassland for water and nutrients. Furthermore, its design, tailored to the characteristics of the inter-row space, can precisely avoid forestry and grassland plants, preventing accidental damage. Compared to traditional weeding methods, this device can complete inter-row weeding operations more efficiently, adapting to the needs of forestry and grassland planting scenarios and ensuring the healthy growth of forestry and grassland.

[0003] Currently, common weeding devices are widely used in weeding between rows of forests and grasslands due to their convenient operation and strong adaptability. However, these devices have certain limitations. When encountering tall or short grass, the angle of the blade needs to be manually adjusted to ensure the weeding effect. During use, the user needs to maintain constant pressure control of the blade to cut the grass. Prolonged operation can easily lead to user fatigue and affect weeding efficiency. Furthermore, the precision of manual control of pressure and angle is limited, which may result in incomplete weeding or accidental damage to the forest and grassland. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an inter-row weeding device for forestry and grassland planting that has the advantage of not requiring continuous manual force to control the blade, thus solving the problems of fatigue and low weeding efficiency caused by users having to maintain continuous force to control the blade during long-term operation in the prior art.

[0005] To address the fatigue and low weeding efficiency experienced by users during prolonged operation due to the need for sustained pressure control, this utility model provides the following technical solution: A weeding device for inter-row planting in forestry and grassland, comprising a weeder, a mounting rod fixedly connected to the bottom center of the weeder, a circular rotating plate rotatably connected to the outside of the mounting rod, a support rod fixedly connected to one side of the outer wall of the circular rotating plate, a support wheel installed on the side of the support rod away from the circular rotating plate, uniformly distributed slots formed on the side of the outer wall of the circular rotating plate away from the support rod, an installation frame fitted onto the outer wall of the circular rotating plate and rotatably connected to the mounting rod, installation blocks fixedly connected to both sides of the inner cavity of the installation frame, a spring being installed through and near the two installation blocks on opposite sides, a locking block provided in the inner cavity of the installation frame, the locking block cooperating with the locking slot, a limit slider fixedly connected to both sides of the locking block, the limit slider sliding within the installation block and fixedly connected to the spring.

[0006] As a further improvement of this utility model, the top two sides of the card block are provided with extrusion grooves.

[0007] As a further improvement of this utility model: a second spring is fixedly connected to one side of the bottom of the inner cavity of the mounting frame, and a foot pedal is fixedly connected to the top of the second spring, and the foot pedal slides within the mounting frame.

[0008] As a further improvement of this utility model: sliding rods are fixedly connected to both sides of the top of the foot pedal, and the sliding rods pass through the extrusion groove and are slidably connected.

[0009] As a further improvement of this utility model: one side of each of the two sliding rods is fixedly connected to an extrusion plate, and the extrusion plate abuts against the extrusion groove.

[0010] As a further improvement of this utility model: a swing groove is provided on one side of the mounting frame, and the support rod swings within the swing groove.

[0011] As a further improvement of this utility model, the output end of the weeding machine is equipped with a blade.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the device controls the engagement and disengagement of the locking block and the slot on the circular rotating plate through the linkage of the foot pedal, sliding rod, squeezing plate, and squeezing groove. Combined with the gravity rotation of the circular rotating plate around the mounting rod and the core support of the support rod and support wheel for the blade head, the device achieves convenient adjustment and stable locking of the blade head's vertical angle. At the same time, during weeding operations, the support of the support wheel and support rod allows the user to complete weeding without continuously applying force to control the blade; simply pushing the device is enough. This device achieves blade head angle adjustment and stable support through mechanical structure linkage, which not only greatly reduces the user's operating burden but also avoids fatigue from prolonged operation.

[0020] 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.

[0021] Please see Figures 1-5In this embodiment of the utility model, a weeding device for inter-row planting of forest and grassland includes a weeder 1. A mounting rod 2 is fixedly connected to the center of the bottom of the weeder 1. A circular rotating plate 3 is rotatably connected to the outside of the mounting rod 2. A support rod 5 is fixedly connected to one side of the outer wall of the circular rotating plate 3. A support wheel 6 is installed on the side of the support rod 5 away from the circular rotating plate 3. Evenly distributed slots 4 are formed on the side of the outer wall of the circular rotating plate 3 away from the support rod 5. A mounting frame 7 is fitted onto the outer wall of the circular rotating plate 3, and the mounting frame 7 is rotatably connected to the mounting rod 2. Mounting blocks 8 are fixedly connected to both sides of the inner cavity of the mounting frame 7. A spring 9 is installed through and attached to one of the two mounting blocks 8 on their relatively close sides. The inner cavity of frame 7 is provided with a locking block 10, which cooperates with the locking slot 4. When the user steps on the foot pedal 13, the foot pedal 13 moves downward under pressure and compresses the second spring 16, simultaneously causing the sliding rod 14 to move downward. The sliding rod 14 passes through the extrusion groove 12 on the locking block 10. During its downward movement, the squeezing plate 15 abuts against the extrusion groove 12, causing the locking block 10 to drive the limiting slider 11 to slide within the mounting block 8 and simultaneously compress the first spring 9, thereby disengaging the locking block 10 from the locking slot 4 on the circular rotating plate 3. Limiting sliders 11 are fixedly connected to both sides of the locking block 10, and the limiting sliders 11 slide within the mounting block 8 and are fixedly connected to the first spring 9. The top two sides of block 10 are provided with extrusion grooves 12. A spring 16 is fixedly connected to one side of the bottom of the inner cavity of the mounting frame 7. A foot pedal 13 is fixedly connected to the top of the spring 16 and slides within the mounting frame 7. Sliding rods 14 are fixedly connected to both sides of the top of the foot pedal 13 and pass through the extrusion grooves 12 and are slidably connected. An extrusion pressure plate 15 is fixedly connected to one side of each of the two sliding rods 14 and both extrusion pressure plates 15 are in contact with the extrusion grooves 12. At this time, the circular rotating plate 3 can rotate around the mounting rod 2 due to gravity, which drives the support rod 5, support wheel 6 and other components to rotate and fit with the ground, ensuring that the support wheel 6 always fits with the ground. The entire device forms the core support for the blade head 18 through the support rod 5 and the support wheel 6. During this process, the installation rod 2 and the up and down angle of the blade head 18 can be adjusted to adapt to grass plants of different heights. After the adjustment is completed, the foot pedal 13 is released, the spring 16 returns to its original position and pushes the foot pedal 13 to move upward. The sliding rod 14 and the squeezing plate 15 return to their original positions. The locking block 10 is re-engaged into the slot 4 under the elastic force of the spring 9, locking the position of the circular rotating plate 3 to fix the angle of the blade head 18. The user only needs to push the device forward to use the blade head 18 with the adjusted angle to clear weeds between the rows of trees and grass. The whole process does not require the user to continuously apply force to control the angle of the blade head 18, which reduces the burden of operation.

[0022] A swing groove 17 is provided on one side of the mounting frame 7, and the support rod 5 swings in the swing groove 17. The output end of the weeder 1 is equipped with a blade head 18. The swing groove 17 on the mounting frame 7 provides space for the support rod 5 to swing, so as to ensure smooth angle adjustment.

[0023] The working principle of this utility model is as follows: When it is necessary to adjust the up and down angle of the blade head 18, the user steps on the foot pedal 13. The foot pedal 13 moves downward under pressure and compresses the second spring 16. At the same time, it drives the sliding rod 14 to move down. The sliding rod 14 passes through the extrusion groove 12 on the locking block 10. During its downward movement, the squeezing plate 15 and the extrusion groove 12 collide, causing the locking block 10 to drive the limiting slider 11 to slide in the mounting block 8 and simultaneously compress the first spring 9. This allows the locking block 10 to disengage from the locking groove 4 on the circular rotating plate 3. At this time, the circular rotating plate 3 can rotate around the mounting rod 2 due to gravity, causing the support rod 5, support wheel 6 and other components to rotate and come into contact with the ground. This ensures that the support wheel 6 always comes into contact with the ground. The entire device forms the core support for the blade head 18 through the support rod 5 and the support wheel 6. In this process, the up and down angles of the mounting rod 2 and the blade head 18 are adjusted to adapt to grass plants of different heights.

[0024] After adjustment, release the foot pedal 13. Spring 2 16 returns to its original position and pushes the foot pedal 13 upward. The sliding rod 14 and the squeezing plate 15 return to their original positions. The locking block 10 re-engages into the slot 4 under the elastic force of spring 1 9, locking the position of the circular rotating plate 3 to fix the angle of the blade head 18. During weeding, the weeder 1 works and the output end drives the blade head 18 to rotate to achieve the weeding action. The support wheel 6 continuously contacts the ground and, with the cooperation of the support rod 5, provides stable support and assists in the movement of the device and the blade head 18. The user only needs to push the device forward to use the blade head 18 with the adjusted angle to clean the weeds between the rows of trees and grass. The whole process does not require the user to continuously apply force to control the angle of the blade head 18, which reduces the operating burden and improves the weeding efficiency and accuracy.
