[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, an electric hedge trimmer includes a base 1, and four universal wheels are arranged at the lower end of the base 1 to realize the movement and steering of the trimmer, so as to facilitate the trimming of the upper end of the hedge at different positions. Of course, in some embodiments, the number of universal wheels includes but is not limited to four. In some embodiments, the number of universal wheels can be more than four, as long as the base 1 can be stably supported and its movement and steering capabilities can be ensured.

[0024] A support frame 2 is fixed to the upper end of the base 1, and a lifting and lowering mounting plate 3 is provided on the support frame 2. An electric chain saw 5 is fixed on the mounting plate 3. The electric chain saw 5 is started to run, and the trimming height of the upper end of the hedge by the electric chain saw 5 is adjusted by controlling the lifting and lowering of the mounting plate 3. As the base 1 moves and turns, the top of the hedge at different positions can be trimmed.

[0025] In this embodiment, the mounting plate 3 is slidably connected to the support frame 2 in the vertical direction, and a screw rod 4 is rotatably connected to the support frame 2. The screw rod 4 passes through the mounting plate 3 in the vertical direction and is threadedly connected thereto. By arranging a motor on the support frame 2 to drive the screw rod 4 to rotate, the height position of the mounting plate 3 can be adjusted; and in order to ensure that the height position of the mounting plate 3 remains stable after adjustment, the screw rod 4 needs to have self-locking properties, that is, the thread lead angle of the screw rod 4 is less than the equivalent friction angle;

[0026] Of course, the method of adjusting the height position of the mounting plate 3 includes but is not limited to the structure such as the screw rod 4 in this embodiment. In some embodiments, the mounting plate 3 can also be directly driven to rise and fall by setting a telescopic rod on the support frame 2, so as to adjust the height position of the mounting plate 3.

[0027] Two absorbing components 6 are mounted on the mounting plate 3, such as Figure 2 As shown, the suction assembly 6 includes a connecting rod 61 mounted on the mounting plate 3, a suction nozzle 62 is fixed on the connecting rod 61, the suction nozzles 62 in the two suction assemblies 6 are respectively located above both sides of the electric chain saw 5, and a suction pipe 63 is connected to the suction nozzle 62. By connecting the suction pipe 63 to the suction source, the broken branches and leaves produced by pruning can be sucked from the suction nozzle 62, so as to prevent a large number of broken branches and leaves from falling on the ground and being difficult to clean up;

[0028] In this embodiment, two cylinders are provided on the mounting plate 3 to respectively drive the two suction nozzles 62 to adjust their positions along the length direction of the electric chain saw 5, so as to adjust the position of the suction nozzle 62 according to the contact position between the electric chain saw 5 and the hedge to improve the adequacy of the absorption of branches and leaves.

[0029] Two storage components 7 are provided at the upper end of the base 1. The two storage components 7 can respectively store the branches and leaves sucked by the two suction nozzles 62 and can provide an air source;

[0030] like Figure 3 and Figure 4 As shown, the storage assembly 7 includes a storage box 71 fixed to the upper end of the base 1, and an air inlet 711 is provided on one side of the storage box 71. The air inlet 711 is used to connect the air inlet 711 to the storage box 71. A through slot 712 is provided on the side of the storage box 71 facing away from the air inlet 711. A suction fan 74 is fixedly installed in the through slot 712. When the suction fan 74 is working, the suction nozzle 62 can generate suction force, thereby sucking the branches and leaves produced by the trimming into the storage box 71; and a mesh plate 73 is installed in the storage box 71. The mesh plate 73 can prevent the branches and leaves from entering the suction fan 74 and interfering with the fan blades, thereby damaging the suction fan, while ensuring the flow of gas in the storage box 71.

[0031] In this embodiment, the upper end of the storage box 71 is open, and an upper cover 72 is fixed to the upper end by bolts to achieve the cover, and the branches and leaves in the storage box 71 can be easily unloaded by removing the upper cover 72;

[0032] In addition, a mounting groove 713 is opened in the storage box 71, and the mesh plate 73 cooperates with the mounting groove 713, and by removing the upper cover 72, the mesh plate 73 can be easily removed from the mounting groove 713, so as to facilitate regular cleaning of the mesh plate 73 to avoid being blocked by branches and leaves, thereby affecting the gas circulation and further affecting the air suction effect.

[0033] It is worth mentioning that, in the present embodiment, the air suction pipe 63 is a hose to ensure that when the mounting plate 3 is raised or lowered, the air suction pipe 63 will not restrict or interfere with the adjustment of the trimming height.

[0034] Working principle:

[0035] By arranging four universal wheels at the lower end of the base 1, arranging a support frame 2 at the upper end of the base 1, arranging a mounting plate 3 that can be raised and lowered on the support frame 2, and fixing an electric chain saw 5 on the mounting plate 3, the adjustment of the trimming height of the top of the hedge is realized; by arranging a suction nozzle 62 on the upper sides of the electric chain saw 5, the suction nozzle 62 is connected to the storage box 71 through the suction pipe 63, and a suction fan 74 is arranged on one side of the storage box 71 to provide a suction source for the suction nozzle 62, and a mesh plate 73 is arranged in the storage box 71 to ensure gas circulation while preventing branches and leaves from entering the suction fan 74, so as to suck the branches and leaves produced by trimming into the storage box 71, and prevent a large number of broken branches and leaves from falling on the ground and being difficult to clean. By arranging a cylinder 64 on the mounting plate 3 to drive the connecting rod 61 and the suction nozzle 62 to adjust the position along the length direction of the electric chain saw 5, it is convenient to adjust the position of the suction nozzle 62 according to the contact position between the electric chain saw 5 and the hedge, so as to improve the adequacy of branch and leaf absorption.
