Description
Technical Field
[0001] The utility model relates to the technical field of gardening, in particular to a high-safety grass trimmer capable of preventing collision. Background Art
[0002] Large-scale ecological green spaces in cities are an indispensable part of urban greening. The area of residential green spaces, road green spaces, and other garden greening areas is constantly increasing. In addition to daily maintenance of green belts, the leaves of the trees wither in autumn and are covered with leaves. Over time, they will become moldy and rot. Part of them will become organic fertilizer, and part of them will breed mold, causing the entire green belt to wither. The dead leaves should be combed out in time.
[0003] In the prior art, most grass combers are used to screen out dead grass leaves from green belts. However, there is no anti-collision structure at the front end of the grass comber. When the grass comber accidentally contacts an obstacle (such as a tree, wall or other obstacle), it is easy to be damaged and the operator may be injured. Summary of the invention
[0004] The purpose of the utility model is to solve the problem that most of the existing technologies use grass combers to screen out dead grass leaves from green belts, but the front end of the grass comber is not provided with an anti-collision structure. When the grass comber accidentally contacts with an obstacle (such as a tree, wall or other obstacle), it is easy to be damaged and the operator is easily injured. A high-safety grass comber with anti-collision is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A high-safety grass comber that can prevent collisions comprises a bottom connecting plate and a U-shaped frame, wherein mounting grooves are symmetrically provided at both ends of the U-shaped frame, an extension column is rotatably connected in the mounting groove, one end of the extension column is fixedly connected to the side surface of the bottom connecting plate, combing teeth are equidistantly provided at the front end of the bottom connecting plate, a pushing frame is obliquely fixedly connected to the side surface of the U-shaped frame, an edge baffle is fixedly connected to the top edge position of the bottom connecting plate, two groups of guide blocks are fixedly connected to the inner walls of the edge baffles, a discharge pipe is fixedly connected to the side gaps of the two groups of guide blocks, and a discharge pipe is provided at one end of the discharge pipe with a discharge component for continuing to discharge leaves.
[0007] Optionally, the outer wall of the extension column is fixedly connected to one end of the torsion spring, and the other end of the torsion spring is fixedly connected to the side of the installation groove.
[0008] Optionally, the unloading assembly includes a limit frame, a unloading plate, and an anti-slip column, and the limit frame is fixedly connected to the top of the guide block.
[0009] Optionally, a discharge plate is movably inserted into the limit frame along the vertical direction, a lifting handle is fixedly provided at the middle position of the top of the discharge plate, and an anti-slip column is fixedly connected to the bottom of the side of the discharge plate.
[0010] Optionally, the front end of the bottom connecting plate is symmetrically rotatably connected to a buffer wheel, and the bottom of the bottom connecting plate is symmetrically fixedly connected to a front running frame.
[0011] Optionally, a rear running frame is symmetrically fixedly connected to the bottom of the U-shaped frame, the length of the front running frame is greater than that of the rear running frame, and running wheels are provided at the bottom of the front running frame and the rear running frame.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] 1. The utility model is provided with a front running frame on the bottom connecting plate, and a rear running frame is provided at the bottom of the U-shaped frame rotatably connected to one end of the bottom connecting plate, and the length of the front running frame is longer than the rear running frame. The front end of the bottom connecting plate is symmetrically rotatably connected to the auxiliary wheel to form an anti-collision structure. When the front end of the bottom connecting plate collides, the bottom connecting plate can rotate around the U-shaped frame at a certain angle under the action of the auxiliary wheel to offset the collision impact, thereby reducing the possibility of equipment damage and operator injury.
[0014] 2. The utility model has guide blocks symmetrically fixedly connected to the top of the bottom connecting plate. The two sets of guide blocks can guide the leaves combed out by the bottom connecting plate into one end of the discharge pipe, and a discharge assembly is provided at one end of the discharge pipe. A recovery bag can be set on the discharge pipe, and the bottom connecting plate can be lifted manually to facilitate the collection of the leaves. BRIEF DESCRIPTION OF THE DRAWINGS
