Abstract
Description
Technical Field
[0001] This application relates to the field of snow removal tools, and more particularly to a handheld tree snow removal device. Background Technology
[0002] Heavy snowfall is common in northern winters, easily accumulating thick snow on tree branches in urban greenbelts and parks. This accumulated snow, adding weight to the branches, can cause them to break, and in severe cases, even lead to the collapse of the entire tree, causing irreversible damage. Furthermore, if the snow isn't cleared promptly, the cold air can easily cause ice to form on the trees. When pedestrians pass by, if this snow and frozen branches break off and fall, they may be injured, creating a safety hazard. Therefore, it's essential for green space management staff to promptly remove snow from trees. Currently, the common method is for workers to stand beneath the trees using long snow-clearing sticks and tap the branches to remove the snow. This method is not only inefficient, but workers are also at risk of being hit by falling snow and ice while actively knocking it off the branches, potentially causing injury. Utility Model Content
[0003] This application provides a handheld tree snow removal device that is not only more efficient to use, but also protects workers during the process of removing snow from trees.
[0004] The above-mentioned objective of this application is achieved through the following technical solution:
[0005] A handheld tree snow removal device includes a hollow main pole, a shield is fixedly fitted on the hollow main pole near its lower end; a striking unit for striking tree branches is installed at the top of the hollow main pole.
[0006] The striking unit includes two striking rods symmetrically arranged on the top of the hollow main rod. A top plate is fixedly welded to the top of the hollow main rod. The lower ends of the two striking rods are movably mounted on the top plate. A reset member is provided on one opposite side of the two striking rods, and a traction member is provided on the other opposite side of the two striking rods.
[0007] The traction member can drive the two striking rods away from each other, and the resetting member can drive the two striking rods closer to each other.
[0008] Furthermore, the traction component includes a hanging lug fixedly installed on the side of one of the striking bars away from the other striking bar, a traction steel wire is tied to the hanging lug, and the end of the traction steel wire away from the hanging lug is fixedly installed on the drive unit located at the bottom of the hollow main rod.
[0009] Furthermore, two brackets are symmetrically installed on the top plate, and each of the two striking rods has a notch at its lower end. The notches of the two striking rods are respectively fitted onto the two brackets, and the notch ends of the striking rods and the corresponding brackets are hinged together by a pin.
[0010] Furthermore, the reset component includes two fixing plates, which are respectively fixedly installed on the same side of the two striking rods. A metal buckle is fixedly installed on the far ends of the two fixing plates, and the two metal buckles are connected by a reset spring.
[0011] Furthermore, a wire-passing hole is provided on one opposite side of the hollow main rod corresponding to the two wire-hanging ears. The traction steel wires on the two wire-hanging ears enter the interior of the hollow main rod through the two wire-passing holes and extend downward to connect with the drive unit.
[0012] Furthermore, the drive unit includes an upper base plate and a lower base plate. The lower ends of the two traction steel wires are fixedly connected to the upper side of the upper base plate, which is located inside the lower end of the hollow main rod. The lower side of the upper base plate is fixedly connected to the lower base plate, which is sealed at the lower end of the hollow main rod, via a connecting rod. A pull ring is installed on the lower side of the lower base plate. The lower end of the hollow main rod converges towards its center, and the inner diameter of the lower end of the hollow main rod after convergence is larger than the diameter of the connecting rod.
[0013] Furthermore, each of the two striking rods has a vertically penetrating groove on its far side, and the two hanging lugs are respectively installed in the grooves on the two striking rods.
[0014] Furthermore, the shield is a transparent umbrella.
[0015] In summary, this application includes at least one of the following beneficial technical effects:
[0016] When snow removal is required on trees, workers can hold the hollow main pole of this application and move it under the tree to be cleared, ensuring that the shield on the hollow main pole is above the worker's head. Then, by manipulating the traction component, the two striking rods located at the top of the hollow main pole are moved away from each other. Releasing the pole causes the two striking rods to close again under the action of the reset component. During this process, the two striking rods collide with the tree branches, shaking them and knocking off the snow, thus achieving the snow removal effect. Because the shield added to the hollow main pole of this application can block snow falling towards the worker, it effectively prevents snow knocked off by the striking rods from hitting the worker and causing injury. Furthermore, the two striking rods of this application can collide with the tree branches simultaneously under the action of the reset and traction components, covering a wider area than when a worker uses a single snow-clearing stick, thus effectively improving the clearing efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0025] like Figures 1-4 As shown, a handheld tree snow removal device disclosed in this application includes a hollow main pole 1, a shield 2 fixedly sleeved on the hollow main pole 1, and the shield 2 is on the hollow main pole 1 near its lower end; a striking unit 3 for striking tree branches is installed on the top of the hollow main pole 1.
[0026] The striking unit 3 includes two striking rods 31 symmetrically arranged on the top of the hollow main rod 1. A top plate 32 is fixedly welded to the top of the hollow main rod 1. The lower ends of the two striking rods 31 are movably mounted on the top plate 32. A reset member 33 is provided on one opposite side of the two striking rods 31, and a traction member 34 is provided on the other opposite side of the two striking rods 31.
[0027] like Figure 5 As shown, the traction member 34 can drive the two striking rods 31 away from each other, and the resetting member 33 can drive the two striking rods 31 closer to each other.
[0028] In the above embodiments, since the hollow main pole 1 needs to be relatively long to meet the effect of the ground worker hitting the tree branches, if the hollow main pole 1 is designed as a solid structure, it will be more difficult for the worker to use it. Therefore, this application designs the hollow main pole 1 as a hollow structure to reduce the force required for the worker to lift the hollow main pole 1, so as to achieve the effect of saving effort.
[0029] When workers in the greening management department need to remove snow from trees, they can move the hollow main pole 1 of this application to the area under the tree to be cleared, and then raise the hollow main pole 1 so that the striking rod 31 at the top of the hollow main pole 1 is close to the area of the tree branches to be cleared. After the hollow main pole 1 is raised to a suitable position, it should be ensured that the shield 2 on the hollow main pole 1 is above the worker's head or diagonally above the side close to the tree (the specific angle of the shield 2 can be determined according to the worker's actual position on site). Then, the worker uses the traction component 34 to drive the two striking rods 31 at the top of the hollow main pole 1 to move away from each other to a certain extent before releasing them. The two striking rods 31 will then move closer to each other under the action of the reset component 33. During the swinging process of the two striking rods 31, the two striking rods 31 will collide with the tree branches, thereby shaking the tree branches and knocking off the snow on the tree, thus achieving the effect of snow removal. During this process, the shield 2 added to the hollow main pole 1 can block the snow falling towards the workers, which can effectively prevent the snow knocked down by the striking rod 31 from hitting the workers and causing personal injury. Moreover, the two striking rods 31 of this application can collide with the tree branches simultaneously under the action of the reset member 33, which is a larger range than the workers using a single snow-clearing stick, thus effectively improving the cleaning efficiency.
[0030] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, the traction component 34 includes a hanging ear 341 fixedly installed on the side of one of the striking bars 31 away from the other striking bar 31. A traction steel wire 342 is tied to the hanging ear 341. The end of the traction steel wire 342 away from the hanging ear 341 is fixedly installed on the drive unit 343 located at the bottom of the hollow main rod 1.
[0031] In the above embodiments, the drive unit 343 for moving the two traction steel wires 342 together is located at the bottom of the hollow main rod 1. This allows the drive unit 343 to be positioned close to the worker's hand after the worker lifts the hollow main rod 1, facilitating operation. The hanging lugs 341 on the outer sides of the two striking rods 31 are connected to the drive unit 343 via a traction steel wire 342. When the worker pulls the drive unit 343 vertically downwards, the drive unit 343 pulls the two striking rods 31 away from each other via the two traction steel wires 342, achieving the effect of quickly unfolding the two striking rods 31.
[0032] Furthermore, such as Figure 2 and Figure 3 As shown, two brackets 4 are symmetrically installed on the top plate 32. The lower end of each of the two striking rods 31 is provided with a notch. The notches of the two striking rods 31 are respectively fitted onto the two brackets 4, and the notch ends of the striking rods 31 and the corresponding brackets 4 are hinged together by a pin 5.
[0033] In the above embodiments, the striking rod 31 is hinged to the corresponding bracket 4 through the notch at its lower end. In this way, the striking rod 31 can swing smoothly in a specific plane under the action of the traction member 34 and the reset member 33, so that the worker can control the cleaning range.
[0034] Furthermore, such as Figure 2 and Figure 3 As shown, the reset component 33 includes two fixing plates 331, which are respectively fixedly installed on the same side of the two striking rods 31. A metal buckle 332 is fixedly installed at the far ends of the two fixing plates 331, and the two metal buckles 332 are connected by a reset spring 333.
[0035] In the above embodiments, the fixing plate 331 on the two striking rods 31 can provide sufficient space for the installation of the return spring 333. Under normal conditions, the return spring 333 can keep the two striking rods 31 in a closed state. When the worker uses the drive unit 343 to move the two striking rods 31 away from each other, the two return springs 333 located on opposite sides of the two striking rods 31 will be stretched synchronously to start accumulating force. After the worker releases the drive unit 343, the two return springs 333 will exert force to pull the two striking rods 31 to quickly move closer to each other. During this process, after the striking rod 31 hits the tree branch, it can release kinetic energy to the tree branch it is in contact with, causing the tree branch to shake. During the shaking of the tree branch, it may hit other nearby branches, thereby achieving an efficient snow removal effect on the tree branches around the striking rod 31.
[0036] Furthermore, such as Figure 2 and Figure 3 As shown, a wire hole 6 is provided on one opposite side of the hollow main rod 1 corresponding to the two wire hanging ears 341. The traction steel wires 342 on the two wire hanging ears 341 enter the hollow main rod 1 through the two wire holes 6 and extend downward to connect with the drive unit 343.
[0037] In the above embodiments, the two traction steel wires 342 can be laid through the wire holes 6 on the hollow main pole 1, using the internal space of the hollow main pole 1 for wiring. Compared with laying the traction steel wires 342 outside the hollow main pole 1, the risk of the traction steel wires 342 getting caught on tree branches during use can be reduced, and the overall structure of the equipment can be made simpler and more aesthetically pleasing.
[0038] Furthermore, such as Figure 4As shown, the drive unit 343 includes an upper base plate 3431 and a lower base plate 3432. The lower ends of the two traction steel wires 342 are fixedly connected to the upper side of the upper base plate 3431, which is located inside the lower end of the hollow main rod 1. The lower side of the upper base plate 3431 is fixedly connected to the lower base plate 3432, which is sealed at the lower end of the hollow main rod 1, through a connecting rod 3433. A pull ring 3434 is installed on the lower side of the lower base plate 3432. The lower end of the hollow main rod 1 converges towards its center, and the inner diameter of the lower end of the hollow main rod 1 after convergence is larger than the diameter of the connecting rod 3433.
[0039] In the above embodiments, after the lower end of the hollow main rod 1 converges inward, its diameter is larger than the diameter of the connecting rod 3433 and smaller than the diameter of the upper base plate 3431. This ensures that the upper base plate 3431 is locked when it moves downward to the lower end of the hollow main rod 1, preventing it from detaching from the hollow main rod 1. Meanwhile, the connecting rod 3433 can smoothly pass through the lower end of the hollow main rod 1 during the movement of the upper base plate 3431. The lower base plate 3432, located outside the lower end of the hollow main rod 1, allows the worker to easily drive the upper base plate 3431 to move along with it via a pull ring 3434, thereby achieving the effect of unfolding the two striking rods 31 and making operation more convenient for the worker. The diameter of the lower base plate 3432 is not smaller than the diameter of the upper base plate 3431, thus preventing the lower base plate 3432 from accidentally retracting into the hollow main rod 1.
[0040] Furthermore, such as Figure 2 and Figure 3 As shown, each of the two striking rods 31 has a groove 7 extending vertically through its opposite side, and two hanging ears 341 are respectively installed in the grooves 7 on the two striking rods 31.
[0041] In the above embodiments, the fixing plate 331 with the reset spring 333 is located on the outside of the striking rod 31, and the hanging ear 341 for binding the traction steel wire 342 is located in the groove 7 of the striking rod 31 between the two fixing plates 331. In this way, when the traction steel wire 342 extends downward toward the drive unit 343, its laying path will not interfere with the two reset members 33, thereby ensuring the smooth operation of the traction steel wire 342 during use.
[0042] Furthermore, the shield 2 is a transparent umbrella.
[0043] In the above embodiments, the shield 2 of this application is set as a transparent umbrella. This not only protects workers during snow removal but also allows workers to easily observe the snow removal progress on trees through the transparent umbrella. Furthermore, the transparent umbrella has the same ribs as a traditional umbrella, allowing it to be folded up for storage, reducing the space it occupies.
[0044] The implementation principle of this embodiment is as follows: When snow removal is required on trees, the worker can hold the hollow main pole 1 of this application and move it to the area below the tree to be cleared. Then, the worker raises the hollow main pole 1, bringing the striking rod 31 at the top of the hollow main pole 1 close to the area of the tree branches to be cleared. After the hollow main pole 1 is raised to a suitable position, it should be ensured that the shield 2 on the hollow main pole 1 is above the worker's head or diagonally above the side near the tree. Next, the worker can repeatedly pull down the pull ring 3434 in the traction component 34. When the pull ring 3434 moves down, it will pass through the lower... The base plate 3432, along with the upper base plate 3431, moves vertically downwards. During this process, the two traction steel wires 342 pull the two striking rods 31 away from each other. When the worker releases their grip, the two striking rods 31 move closer together under the action of the return spring 333. As the worker repeatedly pulls the pull ring 3434, the two striking rods 31 continuously swing up and down. During this swinging process, the two striking rods 31 collide with tree branches, causing the branches to shake and knocking off the snow, thus achieving the snow removal effect. In this process, the shield 2 added to the hollow main pole 1 can block the snow falling towards the worker, effectively preventing the snow knocked off by the striking rods 31 from hitting the worker and causing personal injury. Moreover, the two striking rods 31, under the action of the return member 33, can collide with tree branches simultaneously, covering a larger area than when the worker uses a single snow-clearing stick, thus effectively improving the cleaning efficiency.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 application.
