Description

Technical Field

[0001] This utility model relates to the field of firebreak cleaning technology, specifically a device for regularly cleaning forest firebreaks. Background Technology

[0002] Routine maintenance of forest firebreaks requires timely removal of combustibles (especially fallen leaves) to expose mineral soil on the ground surface, thereby preventing the spread of fire.

[0003] In existing technologies, equipment such as rakes, backpack blowers, and push sweepers are commonly used to clean up combustibles in the belt. However, while these devices are effective on flat ground, they present some problems on slopes: the large undulations of the slope not only make it difficult to use cleaning tools, but also increase the risk of slips, sprains, and other injuries for workers who need to walk and bend over repeatedly on the slope, making it difficult to guarantee the safety of the operation, especially on steeper slopes.

[0004] Based on this, we propose a device for regularly cleaning forest firebreaks. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a regular cleaning device for forest firebreaks, which has the advantage of facilitating the regular cleaning of fallen leaves on the slopes of firebreaks.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned purpose of facilitating the regular cleaning of fallen leaves on firebreak slopes, this utility model provides the following technical solution: a device for regularly cleaning forest firebreaks, comprising:

[0009] The two end plates are connected on opposite sides by a connecting plate and fixed to the top of the slope by ground nails fixed at the bottom.

[0010] The take-up roller is mounted between two end plates via a roller shaft and is used to take up or release the traction rope.

[0011] The other end of the traction rope is fixedly connected to a slide plate, which slides on the slope and has a brush plate installed at the bottom. The bottom of the brush plate is evenly provided with brush bristles.

[0012] Furthermore, one end of the roller shaft passes through an end plate and is fixedly connected to a worm gear, which is rotatably mounted inside a side control box, and the side control box is fixedly mounted on the end plate.

[0013] The outer wall of the worm gear is engaged with a worm, which is fixedly mounted on a rotating shaft. One end of the rotating shaft is rotatably mounted on the inner wall of the side control box, and the other end extends to the outside of the side control box and is fixedly connected to a crank handle.

[0014] Furthermore, rollers are rotatably mounted at both ends of the skateboard.

[0015] Furthermore, both the front and rear edges of the skateboard are chamfered to form an upward-sloping portion.

[0016] Furthermore, the bristles are inclined towards the bottom of the slope.

Detailed Implementation

[0032] 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.

[0033] Example 1:

[0034] Please see Figures 1-3 This embodiment discloses a periodic cleaning device for forest firebreak slopes, the main body of which is a take-up roller 3, such as... Figure 1 As shown, the take-up roller 3 is rotatably mounted between two end plates 1 via a roller shaft. The opposite sides of the two end plates 1 are connected by a connecting plate 2, and are fixed to the top of the slope by ground nails 4 fixedly installed at their bottom ends, forming a stable fixed frame. The function of the take-up roller 3 is to take up or release the traction rope 10. The other end of the traction rope 10 is fixedly connected to a slide plate 11. The slide plate 11 is slidably mounted on the slope, and a brush plate 13 is installed at the bottom. Brush bristles 14 are evenly distributed at the bottom of the brush plate 13.

[0035] One end of the traction rope 10 is connected to the take-up roller 3, and the other end is connected to the slide plate 11. When the traction rope 10 is released, the slide plate 11 slides down the slope under the action of gravity. At this time, the brush 14 can remove the fallen leaves on the slope and collect them at the bottom of the slope. The operator can complete the cleaning without going down the slope, which effectively reduces the risk of slipping, twisting and other operational risks.

[0036] After the slide plate 11 is moved to the bottom of the slope, the traction rope 10 is wound up, which will allow the slide plate 11 to move up the slope. This process is repeated several times to completely clear the fallen leaves from the slope. If the firebreak is wide, the position of the winding roller 3 and the slide plate 11 can be moved to clean other areas.

[0037] In this embodiment, three traction ropes 10 are evenly arranged, which makes the force on the slide plate 11 more balanced and the up and down movement more stable, avoiding the slide plate 11 from tilting due to single-point force.

[0038] In this embodiment, the rotation of the take-up roller 3 is controlled manually, specifically, as follows: Figure 2 As shown, one end of the roller shaft passes through an end plate 1 and is fixedly connected to a worm gear 5. The worm gear 5 is rotatably installed inside the side control box 6. The side control box 6 is fixedly installed on the end plate 1. A worm 7 meshes with the outer wall of the worm gear 5. The worm 7 is fixedly installed on the rotating shaft 8. One end of the rotating shaft 8 is rotatably installed on the inner side wall of the side control box 6, and the other end extends to the outside of the side control box 6 and is fixedly connected to a crank handle 9.

[0039] By cranking the handle 9, the worm 7 can be rotated through the rotating shaft 8. The rotation of the worm 7 drives the meshing worm wheel 5 to rotate. The rotation of the worm wheel 5 drives the take-up roller 3 to rotate through the roller shaft, thereby winding or unwinding the traction rope 10. The transmission of the worm wheel 5 and the worm 7 has a self-locking characteristic, which can stably stop at any position, thereby preventing the slide plate 11 from accidentally slipping due to inertia or rebound.

[0040] like Figure 1 As shown, two rollers 12 are rotatably installed at both ends of the skateboard 11, which makes it easier for the skateboard 11 to move up and down along the slope.

[0041] In this embodiment, as Figure 3 As shown, the front and rear edges of the skateboard 11 are both chamfered to form an upward tilt 15. The upward tilt 15 can improve obstacle crossing ability and passability, and reduce "head-hitting" and jamming.

[0042] Furthermore, such as Figure 4 As shown, the bristles 14 are inclined towards the bottom of the slope, and the downward gravity can form a one-way brush push, which improves the cleaning effect and also facilitates the upward pulling of the slide plate 11.

[0043] Example 2:

[0044] Based on Embodiment 1, in this embodiment, a top groove 16 is provided on the top of the slide plate 11, and a counterweight plate 17 is slidably installed in the top groove 16. Specifically, as shown... Figure 4As shown, a lead screw 18 is rotatably installed inside the top groove 16, and a counterweight plate 17 is screwed onto the lead screw 18. One end of the lead screw 18 is rotatably installed on the inner wall of the top groove 16, and the other end extends to the outside of the top groove 16 and is fixedly connected to an adjusting knob 19.

[0045] The position of the counterweight plate 17 in the top groove 16 can be adjusted by rotating the lead screw 18 driven by the adjusting knob 19. When the counterweight plate 17 moves forward, it is more stable to cross obstacles and is less likely to "drift over" the pile of leaves. At the same time, it can also make the bristles 14 press more tightly and make it easier to remove fallen leaves. When the counterweight plate 17 moves backward, the entire slide plate 11 is easier to slide. The operator can adjust the position of the counterweight plate 17 as needed.

[0046] Example 3:

[0047] Based on Embodiment 1 or Embodiment 2, in this embodiment, as follows: Figure 5 As shown, a mounting block 20 is fixedly installed on the top of the brush plate 13. The mounting block 20 is detachably installed in a slot opened at the bottom of the slide plate 11. Specifically, as shown... Figure 5 The fixing bolt 21 passes through the top of the slide plate 11 into the block groove and is screwed into the bolt groove opened on the top of the mounting block 20;

[0048] Therefore, by unscrewing the fixing bolt 21, the brush plate 13 can be quickly replaced and maintained, reducing the cost of use.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
