Description

Technical Field

[0001] The utility model relates to the technical field of forestry weeders, and more specifically, it relates to a forestry weeder with an avoidance mechanism. Background Technique

[0002] A forestry weeder is a mechanical device specifically used for weed and grass management in forests, forest lands, gardens, and other similar areas. It is mainly used to remove weeds, shrubs, low-growing trees, and other unwanted vegetation in places with trees and dense vegetation for the purpose of tidying and maintenance. However, the existing weeders are relatively bulky, and for areas that are difficult to clean, the operator needs to use their own arm strength to control the entire device to perform the removal, consuming a large amount of physical strength of the staff.

[0003] When the existing forestry weeder is in use, due to the lack of a reasonable avoidance mechanism, to avoid damaging the trees, the weeding operator needs to precisely control the movement of the forestry weeder and keep a certain distance from the trees. However, precise control of the movement of the forestry weeder requires the weeding operator to have relatively high work experience, and novices cannot achieve precise control when operating the forestry weeder, resulting in incomplete weeding or damage to the trees. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a forestry weeder with an avoidance mechanism, which has the characteristic of automatic avoidance.

A slide rail is fixedly connected to the upper surface of the weeding mechanism. Two connecting plates are slidably connected to the surface of the slide rail. Two avoidance wheels are rotatably connected to the surfaces of the two connecting plates through bearings. The two avoidance wheels are symmetrically arranged on the surface of the slide rail. An avoidance component is fixedly connected to the surface of the weeding mechanism. The avoidance component includes a slide plate, a square slide rod, a traction arm, and two support springs. An adjustment component is fixedly connected to the upper surface of the weeding mechanism. The adjustment component includes two support plates, a rotating shaft, a left-right threaded column, two threaded nuts, and a handwheel.

[0008] When using a forestry weeder with an avoidance mechanism of this technical solution, by setting the avoidance wheels, when the weeding mechanism is about to touch a tree, the avoidance wheels touch the tree first to form an isolation. By setting the avoidance component, under the action of the avoidance wheels, the tree drives the weeding mechanism to slide on the surface of the square slide rod, thereby avoiding damage to the tree by the weeder.

[0033] Embodiment:

[0034] The following is a further detailed description of the present utility model in conjunction with the attached Figures 1-3 drawings.

[0035] Please refer to Figures 1-3, the present utility model provides a technical solution: a forestry weeding machine with an avoidance mechanism, including a weeding mechanism 1. A slide rail 2 is fixedly connected to the upper surface of the weeding mechanism 1. Two connecting plates 3 are slidably connected to the surface of the slide rail 2. Two avoidance wheels 4 are rotatably connected to the surfaces of the two connecting plates 3 through bearings. The two avoidance wheels 4 are symmetrically arranged on the surface of the slide rail 2. An avoidance component 5 is fixedly connected to the surface of the weeding mechanism 1. The avoidance component 5 includes a slide plate 501, a square slide rod 502, a traction arm 503 and two support springs 504. An adjustment component 6 is fixedly connected to the upper surface of the weeding mechanism 1. The adjustment component 6 includes two support plates 601, a rotating shaft 602, a left - right threaded column 603, two threaded nuts 604 and a handwheel 605. By providing the avoidance wheels 4, when the weeding mechanism 1 is about to touch a tree, the avoidance wheels 4 first touch the tree to form an isolation. By providing the avoidance component 5, under the action of the avoidance wheels 4, the tree drives the weeding mechanism 1 to slide on the surface of the square slide rod 502, thus preventing the weeding machine from damaging the tree.

[0036] Specifically, the slide plate 501 is fixedly connected to the surface of the weeding mechanism 1. The square slide rod 502 is slidably connected to the surface of the slide plate 501. The traction arm 503 is fixedly connected to both ends of the square slide rod 502. The two support springs 504 are sleeved on the surface of the square slide rod 502.

[0037] By adopting the above - mentioned technical solution, by providing the slide plate 501, under the action of the avoidance wheels 4, the tree pushes the weeding mechanism 1 and the slide plate 501 to slide on the surface of the square slide rod 502, making the weeding mechanism 1 move away from the tree, thus preventing the weeding machine from damaging the tree. By providing the two support springs 504, it is convenient to reset the slide plate 501 and the weeding mechanism 1.

[0038] Specifically, the two support plates 601 are both fixedly connected to the upper surface of the weeding mechanism 1. The rotating shaft 602 is rotatably connected to the surfaces of the two support plates 601 through bearings. The left - right threaded column 603 is penetrated through the surface of the rotating shaft 602. The two threaded nuts 604 are respectively threadedly connected to the surface of the left - right threaded column 603. The two threaded nuts 604 are respectively fixedly connected to the surfaces of the two connecting plates 3. The handwheel 605 is fixedly connected to one end of the rotating shaft 602.

[0039] By adopting the above - mentioned technical solution, by rotating the handwheel 605, the rotating shaft 602 and the left - right threaded column 603 are driven to rotate, making the two threaded nuts 604 and the two connecting plates 3 slide on the surface of the slide rail 2, thus facilitating the adjustment of the distance that the avoidance wheels 4 extend out of the weeding mechanism 1, and thus adjusting the safety distance between the weeding mechanism 1 and the tree to protect the tree roots.

[0040] Specifically, indicating plates 7 are respectively fixedly connected to the surfaces of the two threaded nuts 604. A scale line 8 is arranged on the surface of the weeding mechanism 1.

[0041] By adopting the above technical solution, by providing the indicator board 7 and the scale line 8, it is convenient to observe the distance that the avoidance wheel 4 extends out of the weeding mechanism 1.

[0042] Specifically, rubber pads 9 are respectively provided on the surfaces of the two avoidance wheels 4.

[0043] By adopting the above technical solution, by providing the rubber pads 9, it is possible to avoid the impact of the avoidance wheels 4 on the trees and cause damage to them.

[0044] The working principle of the present utility model is as follows: When in use, the staff adjusts the protection distance of the weeding mechanism 1 as needed. By rotating the hand wheel 605, the rotating shaft 602 and the positive and negative threaded column 603 are driven to rotate, so that the two threaded nuts 604 and the two connecting plates 3 slide on the surface of the slide rail 2. Under the action of the indicator board 7 and the scale line 8, the distance that the avoidance wheel 4 extends out of the weeding mechanism 1 is adjusted. The staff operates the weeding equipment and the weeding mechanism 1 to perform the weeding work. When the avoidance wheel 4 hits the surface of the tree, the tree pushes the weeding mechanism 1 and the slide plate 501 to slide on the surface of the square slide bar 502 through the avoidance wheel 4, so that the weeding mechanism 1 is far away from the tree, avoiding damage to the tree by the weeding mechanism 1. When separating from the tree, the support spring 504 drives the slide plate 501 and the weeding mechanism 1 to reset, facilitating the avoidance action to be performed again.

[0045] This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
