Description

Technical Field

[0001] This utility model relates to the field of forestry planting technology, and in particular to a strip weeding device for forestry planting. Background Technology

[0002] In forestry planting, weeds compete with seedlings for nutrients, water, and sunlight, severely impacting their healthy growth. Therefore, weeding is a crucial aspect of forestry planting and maintenance. Traditional manual weeding methods are inefficient and labor-intensive; while spraying chemical herbicides easily pollutes the soil and environment, failing to meet the requirements of green forestry development. With the development of forestry mechanization, belt weeding devices have become widely used due to their high efficiency. These devices achieve mobile operation through track transmission. However, existing belt weeding devices for forestry planting often face the problem of difficult track tension adjustment. If the track is too loose, slippage can occur, affecting the normal operation and weeding efficiency of the device; if the track is too tight, it will accelerate wear on the track and transmission components, shortening the equipment's lifespan and increasing energy consumption. Currently available adjustment mechanisms are complex, inconvenient to operate, and lack precision, failing to meet the diverse operational needs of forestry planting.

[0003] Therefore, we propose a forestry planting strip weeding device. Utility Model Content

[0004] The main purpose of this utility model is to provide a forestry planting belt weeding device. This device aims to prevent slippage caused by loose tracks, which could affect the normal operation and efficiency of the weeding device, and to address the problems of excessively tight tracks leading to increased wear, shortened equipment lifespan, and increased energy consumption. It also solves the shortcomings of existing adjustment structures, such as complex operation, inconvenience, and insufficient precision. This improves the accuracy and ease of operation of track tension adjustment, ensures the stability and reliability of the weeding device, extends equipment lifespan, reduces maintenance costs, and enhances the overall efficiency and economic benefits of forestry weeding operations. This effectively solves the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A forestry planting strip weeding device includes a mobile frame, with grooves on both rear sides of the mobile frame. Sliding blocks are slidably connected in the two grooves, and driven wheels are connected to the two sliding blocks through bearings.

[0007] A wedge block is slidably connected up and down in the slide groove. One side of the slider is provided with an inclined surface that matches the wedge block. A screw is threadedly connected to the top of the movable frame and located in the slide groove. The bottom end of the screw is connected to the top end of the wedge block through a bearing. A force-adding rod is inserted into the upper part of the screw.

[0008] By adopting the above technical solution, rotating the force-adding rod drives the screw to rotate. Since the screw is threadedly connected to the mobile frame, it drives the wedge block to move up and down within the groove. When the wedge block moves downward, it cooperates with the inclined surface on the slider to push the slider to move back and forth within the groove, thereby adjusting the position of the driven wheel and adjusting the track tension to ensure the stability of the track drive.

[0009] Furthermore, the screw is externally threaded with a locking nut, and a rotating rod is welded to one side of the outer wall of the locking nut.

[0010] By adopting the above technical solution, after the position of the wedge block is adjusted by the screw, the rotating rod is rotated, which drives the locking nut to rotate on the screw and press against the top of the moving frame, thereby locking and fixing the screw, preventing the screw from rotating due to vibration and other factors during the use of the device, ensuring the stability of the wedge block position, and thus maintaining the stability of the track tension.

[0011] Furthermore, the bottom end of the slider and the other side of the wedge block are integrally formed with a limiting block, and the inner wall of the bottom end and one side of the sliding groove are provided with a limiting groove that slides and connects with the limiting block.

[0012] By adopting the above technical solution, when the slider and wedge block move within the slide groove, the limiting block slides synchronously within the limiting groove. The limiting groove guides and limits the limiting block, preventing the slider and wedge block from shifting or disengaging from the slide groove during movement, ensuring the accuracy and stability of the slider and wedge block's movement, and thus ensuring the reliability of track tension adjustment.

[0013] Furthermore, both sides of the front of the mobile frame are rotatably connected to drive wheels, and the drive wheels and driven wheels are connected by track drive.

[0014] By adopting the above technical solution, the drive wheel rotates, which in turn drives the driven wheel to rotate through the track. The track contacts the ground, and the friction between the track and the ground enables the device to move stably on complex terrains such as forests, providing a mobile foundation for weeding operations.

[0015] Furthermore, motors are fixedly connected to the front of the inner walls on both sides of the mobile frame, and the output shaft of the motor passes through the mobile frame and is fixedly connected to the drive wheel.

[0016] By adopting the above technical solution, the motor is started, the output shaft of the motor rotates, which drives the drive wheel to rotate. The drive wheel drives the driven wheel to rotate through the track, thereby providing power for the movement of the device and realizing the autonomous movement of the device, which facilitates the mobile operation of weeding in forest planting areas.

[0017] Furthermore, two auxiliary wheels are rotatably connected to both sides of the mobile frame, and a frame for supporting the weeding mechanism is fixedly connected to the top of the mobile frame.

[0018] By adopting the above technical solution, the auxiliary wheels support the tracks, enabling them to maintain a suitable shape and position, reducing sagging and deformation, and ensuring the smoothness of track transmission. Simultaneously, the frame is used to install and support the weeding mechanism, allowing it to perform weeding operations stably and providing structural support for the weeding work.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) This utility model of a forestry planting belt weeding device uses a rotating force rod to drive a screw to rotate. The screw is connected to the moving frame via a threaded connection, enabling the wedge block to move up and down within a groove. The cooperation between the wedge block and the inclined surface of the slider allows for precise movement of the slider back and forth within the groove, thereby accurately adjusting the position of the driven wheel and effectively regulating the track tension. Compared to traditional adjustment methods, this structure can quickly and accurately adjust the track tension to the optimal state according to different operating environments and equipment operating conditions, avoiding slippage due to excessively loose tracks or wear due to excessively tight tracks. This greatly improves the stability and reliability of the weeding device, ensuring efficient forestry weeding operations.

[0021] (2) This utility model relates to a forestry planting strip weeding device. The device features an ingeniously designed adjustment structure, allowing for easy adjustment of the track tension simply by rotating the lever, eliminating the need for complex tools and cumbersome procedures. Operators can easily master the adjustment method and quickly address track tension issues, effectively saving equipment maintenance time and labor costs. Furthermore, the simple adjustment structure reduces the probability of equipment failure and maintenance frequency, further enhancing the practicality and economy of the forestry planting strip weeding device, reducing operator workload, and improving work efficiency.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] To prevent slippage caused by excessively loose tracks, which could affect the normal operation and efficiency of the weeding device, and to address the problems of excessively tight tracks exacerbating wear, shortening equipment lifespan, and increasing energy consumption, this solution aims to resolve the shortcomings of existing adjustment mechanisms, such as complexity, inconvenience, and insufficient precision. This will improve the accuracy and ease of operation of track tension adjustment, ensure the stability and reliability of the weeding device, extend equipment lifespan, reduce maintenance costs, and enhance the overall efficiency and economic benefits of forestry weeding operations. Figure 1 , Figure 2 , Figure 3 As shown, the forestry planting strip weeding device includes a mobile frame 1. The mobile frame 1 has a sliding groove 2 on both rear sides. The two sliding grooves 2 are connected to a slider 3 in a sliding manner. The two sliders 3 are connected to a driven wheel 4 through a bearing.

[0028] A wedge block 5 is slidably connected up and down in the slide groove 2. One side of the slider 3 is provided with an inclined surface 6 that matches the wedge block 5. A screw rod 7 is threadedly connected to the top of the movable frame 1 and located in the slide groove 2. The bottom end of the screw rod 7 is connected to the top end of the wedge block 5 through a bearing. A force-adding rod 8 is inserted into the upper part of the screw rod 7.

[0029] In use, rotating the extension rod 8 causes the screw 7 to rotate. Since the screw 7 is threadedly connected to the mobile frame 1, it drives the wedge block 5 to move up and down within the slide groove 2. When the wedge block 5 moves downward, it engages with the inclined surface 6 on the slider 3, pushing the slider 3 to move back and forth within the slide groove 2. This adjusts the position of the driven wheel 4, thereby regulating the tension of the track 15 and ensuring the stability of the track 15 transmission.

[0030] For example, such as Figure 3 As shown, the present invention also includes a locking nut 9 connected to the external thread of the screw 7, and a rotating rod 10 welded to one side of the outer wall of the locking nut 9.

[0031] When in use, after adjusting the position of the wedge block 5 by means of the screw 7, rotate the rotating rod 10 to drive the locking nut 9 to rotate on the screw 7 and press against the top of the moving frame 1, thereby locking and fixing the screw 7 to prevent the screw 7 from rotating due to vibration or other factors during the use of the device, ensuring the stability of the position of the wedge block 5, and thus maintaining the stability of the track tension 15.

[0032] For example, such as Figure 3 As shown, the present invention also includes a limiting block 11 integrally formed at the bottom end of the slider 3 and the other side of the wedge block 5, and a limiting groove 12 that slides and connects to the limiting block 11 is provided on the bottom inner wall and one side inner wall of the slide groove 2.

[0033] During use, as the slider 3 and wedge block 5 move within the slide groove 2, the limiting block 11 slides synchronously within the limiting groove 12. The limiting groove 12 guides and limits the limiting block 11, preventing the slider 3 and wedge block 5 from shifting or disengaging from the slide groove 2 during movement. This ensures the accuracy and stability of the movement of the slider 3 and wedge block 5, thereby ensuring the reliability of the track tension adjustment.

[0034] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a drive wheel 13 rotatably connected to the front of both sides of the mobile frame 1, and the drive wheel 13 and the driven wheel 4 are connected by a track 15 for transmission.

[0035] When in use, the drive wheel 13 rotates, which drives the driven wheel 4 to rotate through the track 15. The track 15 contacts the ground, and the friction between the track 15 and the ground enables the device to move stably on complex terrains such as forests, providing a mobile basis for weeding operations.

[0036] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes motors 14 fixedly connected to the front of the inner walls on both sides of the mobile frame 1, and the output shaft of the motors 14 passes through the mobile frame 1 and is fixedly connected to the drive wheel 13.

[0037] When in use, the motor 14 is started, and the output shaft of the motor 14 rotates, driving the drive wheel 13 to rotate. The drive wheel 13 drives the driven wheel 4 to rotate through the track 15, thereby providing power for the movement of the device and enabling the device to move autonomously, which facilitates the mobile operation of weeding in forestry planting areas.

[0038] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes two auxiliary wheels 16 rotatably connected to both sides of the mobile frame 1, and a frame 17 for supporting the weeding mechanism is fixedly connected to the top of the mobile frame 1.

[0039] During operation, the auxiliary wheels 16 support the tracks 15, ensuring they maintain a proper shape and position, reducing sagging and deformation, and guaranteeing smooth transmission. Simultaneously, the frame 17 mounts and supports the weeding mechanism, enabling it to perform weeding operations stably and providing structural support for the weeding work.

[0040] It should be noted that this utility model is a forestry planting belt weeding device. Rotating the force-adding rod 8 drives the screw 7 to rotate. Because the screw 7 is threadedly connected to the mobile frame 1, the wedge block 5 will move up and down in the slide groove 2. When the wedge block 5 moves downward, it will push the slider 3 to move back and forth in the slide groove 2 through the cooperation with the inclined surface 6 on the slider 3, thereby adjusting the position of the driven wheel 4 to adjust the tension of the track 15. After adjusting the position of the wedge block 5, rotating the rotating rod 10 will drive the locking nut 9 to rotate on the screw 7 and press against the top of the mobile frame 1, locking and fixing the screw 7 to ensure the stability of the wedge block 5 position and maintain the stability of the track 15 tension. When the slider 3 and the wedge block 5 move, the limiting block 11 slides synchronously in the limiting groove 12. The limiting groove 12 plays a guiding and limiting role for the limiting block 11, ensuring that the two move accurately and stably. Next, motor 14 is started. The output shaft of motor 14 rotates, driving the drive wheel 13 to rotate. The drive wheel 13 drives the driven wheel 4 to rotate via track 15. Track 15 contacts the ground, using friction to enable the device to move stably on complex terrains such as forests. At the same time, auxiliary wheel 16 supports track 15, reducing sagging and deformation and ensuring smooth transmission. Finally, the device moves to the weeding area in the forestry planting zone using track 15. The weeding mechanism mounted on frame 17 performs weeding operations. Auxiliary wheel 16 continuously supports track 15, and frame 17 provides stable support for the weeding mechanism, ensuring smooth weeding.
