Description

Highway maintenance slope weeding device Technical Field

[0001] This utility model relates to the technical field of weeding devices, specifically a slope weeding device for highway maintenance. Background Technology

[0002] A slope is a slope with a certain gradient created on both sides of the roadbed to ensure its stability. To prevent vegetation on the slope surface from affecting the road, workers usually use weeding devices to remove weeds from the slope surface.

[0003] Utility model patent CN215530038U discloses a slope weeding device, belonging to the technical field of weeding devices. It addresses the problems in existing technologies where, during weeding, roots and stems become entangled around the weeding blade, hindering effective cutting and thus reducing weeding efficiency. It also addresses the issue of the sliding sleeve's inability to effectively lift and limit its movement, causing it to wobble and affecting the blade's sliding motion. The device includes a handle, a fixed base, a driver, a power cord, a transmission assembly, and a weeding blade. The anti-tangle mechanism is designed with an anti-tangle feature on the handle surface. When the reciprocating screw rotates, the sliding sleeve drives the cutter to slide back and forth, cutting off the tangled roots and stems. This effectively prevents the roots and stems from tangling and thus reduces weeding efficiency. Furthermore, the sliding sleeve has an internal sliding mechanism that moves the pulley as it slides. The pulley slides along the guide groove surface for limiting the sliding motion, thus improving the stability of the sliding sleeve during movement and preventing it from wobbling.

[0004] However, the above patent still has shortcomings: although the patent can cut weeds on the slope surface, when using it, the staff needs to lift the entire device for suspended operation. Due to the large weight of the device, it is more difficult for the user to remove weeds. In addition, the device cuts weeds with a cutting blade, but the cutting area is small and the weeding efficiency is not good. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a slope weeding device for highway maintenance, which solves the problems mentioned in the background art. Although the existing slope weeding devices for highway maintenance can cut weeds on the slope surface, they require workers to lift the entire device for suspended operation. Due to the large weight of the device, it is difficult for users to weed. In addition, the device cuts weeds with a cutting blade, resulting in a small cutting area and poor weeding efficiency.

[0025] 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.

[0026] Please refer to Figures 1 to 6. The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A slope weeding device for highway maintenance includes: a base plate 1; a housing 2 is fixedly connected to the top of the base plate 1, a connecting frame 3 is fixedly connected to the center of the bottom of the base plate 1, a fixing plate 4 is fixedly connected inside the connecting frame 3, a cutting plate 5 is provided on the top of the fixing plate 4, and the cutting plate 5 cooperates with the fixing plate 4; a weeding mechanism 6 is provided on the top of the cutting plate 5 to control the cutting plate 5 to cut weeds; a power mechanism 7 is provided on one side of the top of the base plate 1 to improve the weeding efficiency of the device. The user can control the cutting plate 5 to move rapidly back and forth horizontally on the top of the fixing plate 4 through the cooperation of the power mechanism 7 and the weeding mechanism 6 while pushing the device to move on the slope surface, thereby cutting the weeds on the slope surface.

[0028] As shown in Figures 2 to 5, the weeding mechanism 6 includes: a sliding rod 8 is provided on the top of the cutting plate 5, both ends of the sliding rod 8 are fixedly connected to the connecting frame 3, and sliders 9 are slidably connected to the outer surfaces of both ends of the sliding rod 8, the bottom of the sliders 9 are fixedly connected to the cutting plate 5; an L-shaped connecting rod 10 is fixedly connected to the top of each slider 9, the end of the L-shaped connecting rod 10 away from the slider 9 passes through the first fixing frame 11 and extends to the guide rail 12, the L-shaped connecting rod 10 is fixedly connected to the guide rail 12, the L-shaped connecting rod 10 is slidably connected to the first fixing frame 11, the first fixing frame 11 is fixedly connected to the base plate 1, a matching cylindrical block 13 is provided inside the guide rail 12, a circular plate 14 is fixedly connected to the top of the cylindrical block 13, and the center of the circular plate 14 is... A first rotating shaft 15 is fixedly connected. The top end of the first rotating shaft 15 passes through the first fixed frame 11 and extends to the outside of the first fixed frame 11. The first rotating shaft 15 is rotatably connected to the first fixed frame 11. While the first rotating shaft 15 rotates rapidly inside the first fixed frame 11, it drives the circular plate 14 to rotate. While the circular plate 14 rotates, it drives the cylindrical block 13 to rotate. While the cylindrical block 13 rotates, it drives the guide rail 12. The guide rail 12 drives the L-shaped connecting rod 10 to slide horizontally back and forth inside the first fixed frame 11. While the L-shaped connecting rod 10 slides, it drives the slider 9. While the slider 9 slides on the surface of the sliding rod 8, it drives the cutting plate 5, so that the cutting plate 5 moves horizontally back and forth continuously on the top of the fixed plate 4.

[0029] As shown in Figure 6, the power mechanism 7 includes: a second fixed frame 16 fixedly connected to one side of the bottom of the base plate 1; a motor 17 fixedly connected to the top of the second fixed frame 16; a second rotating shaft 18 fixedly connected to the output end of the motor 17; the bottom end of the second rotating shaft 18 passing through the second fixed frame 16 and extending to the first synchronous pulley 19; the first synchronous pulley 19 fixedly connected to the second rotating shaft 18; the second rotating shaft 18 rotatably connected to the second fixed frame 16; and the first synchronous pulley 19 connected to the second synchronous pulley 21 via a synchronous belt 20. The diameter of the first synchronous pulley 19 is larger than that of the second synchronous pulley 21. The second synchronous pulley 21 is fixed to the outer surface of the first rotating shaft 15. When the motor 17 is started, the output end of the motor 17 drives the second rotating shaft 18. The second rotating shaft 18 rotates with the cooperation of the second fixed frame 16. While rotating, the second rotating shaft 18 drives the first synchronous pulley 19. The first synchronous pulley 19 drives the second synchronous pulley 21 to rotate through the synchronous belt 20. While rotating, the second synchronous pulley 21 drives the first rotating shaft 15 to rotate. Since the diameter of the first synchronous pulley 19 is larger than that of the second synchronous pulley 21, the rotation speed of the second synchronous pulley 21 is increased.

[0030] As shown in Figure 2, a control box 22 containing a storage battery is provided on one side of the second fixed frame 16. The control box 22 is fixedly connected to the base plate 1. The storage battery can not only provide power to the device, but also be connected to the power source through wires, which increases the flexibility of the device.

[0031] As shown in Figure 2, a push rod 23 is fixedly connected to one side of the housing 2. Mounting plates 26 are provided at the four corners of the bottom of the base plate 1. Universal wheels 24 are fixedly connected to the bottom of each mounting plate 26. Four bolts 25 are provided at the top of the base plate 1 near the mounting plate 26. The bottom ends of the bolts 25 penetrate the base plate 1 and the mounting plate 26 and extend to the nuts. The nuts are threadedly connected to the bolts 25. The push rod 23 cooperates with the universal wheels 24. The user can not only move the device by pushing the device through the cooperation of the push rod 23 and the universal wheels 24, but also replace the universal wheels 24 with severe wear through the cooperation of the bolts 25 and the nuts.

[0032] As shown in Figure 4, the fixed plate 4 has several first toothed grooves 27 evenly distributed on the side away from the connecting frame 3. The cutting plate 5 has second toothed grooves 28 distributed near the first toothed grooves 27. The first toothed grooves 27 and the second toothed grooves 28 cooperate with each other. When the cutting plate 5 moves back and forth, it drives the second toothed grooves 28, so that the second toothed grooves 28 on the cutting plate 5 continuously interweave with the first toothed grooves 27 on the fixed plate 4, thereby cutting the weeds and achieving the purpose of weeding.

[0033] As shown in Figures 1 and 2, the side of the housing 2 away from the push rod 23 is set to be arc-shaped, which reduces the wind resistance in the direction of movement of the device, making it easier for the user to push the device and improving its practicality.

[0034] Working principle: The user can start the motor 17 while the device moves on the slope surface. The output of the motor 17 drives the second rotating shaft 18. The second rotating shaft 18 rotates with the cooperation of the second fixed frame 16. The rotation of the second rotating shaft 18 drives the first synchronous pulley 19. The first synchronous pulley 19 drives the second synchronous pulley 21 to rotate through the synchronous belt 20. The rotation of the second synchronous pulley 21 drives the first rotating shaft 15 to rotate. The first rotating shaft 15 rotates rapidly inside the first fixed frame 11, while driving the circular plate 14 to rotate. The rotation of the circular plate 14 drives the cylindrical block 13 to rotate. The rotation of the cylindrical block 13 drives the guide rail 12. The guide rail 12 drives the L-shaped connecting rod 10 to slide horizontally back and forth inside the first fixed frame 11. The L-shaped connecting rod 10 slides horizontally while... The slider 9 moves along the surface of the sliding rod 8, which in turn drives the cutting plate 5. This causes the cutting plate 5 to move horizontally back and forth on the top of the fixed plate 4. As the cutting plate 5 moves back and forth, it drives the second tooth groove 28, causing the second tooth groove 28 on the cutting plate 5 to interlock with the first tooth groove 27 on the fixed plate 4, thereby cutting the weeds and achieving the purpose of weeding. This allows the user to push the device to move while cutting the weeds on the slope surface, making it easier for the user to weed the slope. This solves the problem that although existing highway maintenance slope weeding devices can cut the weeds on the slope surface, they require the operator to lift the entire device for suspended operation. Due to the large weight of the device, it is difficult for the user to weed.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
