[0034] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or a connection through an intermediate medium. It can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0035] As Figures 1 to 5 shown, the automatic hedge trimmer of the present utility model includes a frame 10 and two trimming mechanisms 20 assembled on the frame 10 and having the same structure; wherein the trimming mechanism 20 includes a lifting assembly 21 assembled on the frame 10, a telescopic assembly 22 drivingly connected to the lifting assembly 21, a connecting rod 23 fixed to one end of the telescopic assembly 22, and a trimming assembly 24 hinged to one end of the connecting rod 23. The lifting assembly 21 drives the trimming assembly 24 to lift, the telescopic assembly 22 drives the trimming assembly 24 to extend and retract, and the trimming assembly 24 trims the hedge, improving the quality and efficiency of hedge trimming.

[0036] In practical applications, the frame 10 is installed on a vehicle 40, the lifting assembly 21 and the telescopic assembly 22 are started, and the position of the trimming assembly 24 is adjusted; while driving the vehicle 40, the trimming assembly 24 is started at the same time. During the process of the vehicle 40 traveling, the trimming assembly 24 automatically trims the hedge; in order to adapt to hedges of different shapes, it can rotate to adjust the angle of the trimming assembly 24; at the same time, since there are two trimming mechanisms 20 and a double-station structure is adopted, the top and side surfaces of the hedge belt can be trimmed simultaneously; after the trimming vehicle is completed, the scissors can be adjusted to be vertically downward and retracted close to the vehicle body; an information display screen is installed in the cab of the vehicle 40 and has a data setting function, and the working condition is observed in combination with the monitoring on the vehicle 40.

[0037] A further improvement to the above solution is that the frame 10 includes a base 11, two columns 12 vertically fixed to the upper end of the base 11, and a mounting plate 13 fixed to the upper ends of the columns 12; the lifting assembly 21 is arranged at the upper end of the mounting plate 13, a limiting cavity is formed between the two columns 12, and the telescopic assembly 22 is always movable within the limiting cavity to ensure the vertical lifting of the telescopic assembly 22.

[0038] A further improvement to the above solution is that the telescopic assembly 22 includes a connecting housing 221, a driving motor 222 fixed to the connecting housing 221, and a movable arm 223 movably connected to the inner side of the connecting housing 221; the connecting housing 221 is a hollow structure with openings at both ends, one end of the movable arm 223 is fixedly connected to the connecting rod 23, and the driving motor 222 drives the trimming assembly 24 to extend and retract along the length direction of the connecting housing 221 according to the PLC control program to adjust the position of the trimming assembly 24. Rolling bearings 223b are arranged on both sides of the movable arm 223, and the rolling bearings 223b roll with the connecting housing 221 to realize the extension and retraction of the movable arm 223.

[0039] Furthermore, the telescopic assembly 22 further includes a first wire reel 224, a first steel wire rope 2251, and a second steel wire rope 2252. The first wire reel 224 is fixedly connected to the main shaft of the driving motor 222; at the same time, a first pulley 226 is provided at the opening at one end of the connecting housing 221, and a second pulley 227 is provided at the opening at the other end of the connecting housing 221. As Figure 4 shown, the first steel wire rope 2251 includes a first end 2251a and a second end 2251b. The first end 2251a is fixedly connected to the first wire reel 224 by a knotted and heat-fused connection method. The first steel wire rope 2251 successively bypasses the first wire reel 224 and the first pulley 226, and the second end 2251b is fixedly connected to the movable arm 223. As Figure 4 shown, the second steel wire rope 2252 includes a third end 2252a and a fourth end 2252b. The third end 2252a is fixedly connected to the first wire reel 224 by a knotted and heat-fused connection method or other connection methods. The second steel wire rope 2252 successively bypasses the first wire reel 224 and the second pulley 227, and the fourth end 2252b is fixedly connected to the movable arm 223.

[0040] When the driving motor 222 rotates forward, the first steel wire rope 2251 is in the wire-releasing state, and the second steel wire rope 2252 is in the wire-winding state. At this time, the movable arm 223 extends along the length direction of the connecting housing 221; conversely, when the driving motor 222 rotates reversely, the first steel wire rope 2251 is in the wire-winding state, and the second steel wire rope 2252 is in the wire-releasing state. At this time, the movable arm 223 retracts along the length direction of the connecting housing 221.

[0041] Furthermore, a first connecting plate 221a is fixedly provided at one end of the connecting housing 221 facing the trimming assembly 24. A second connecting plate 223a is fixedly provided at the outer end of the movable arm 223. A bellows 228 is provided between the first connecting plate 221a and the second connecting plate 223a. A power cord 229 is provided inside the bellows 228. One end of the power cord 229 is connected to the trimming assembly 24 to provide power for the trimming assembly 24 to ensure its operation. The bellows 228 plays a role in protecting the wire.

[0042] A further improvement to the above solution is that a guiding assembly 30 is provided on the side wall of the connecting housing 221. The guiding assembly 30 includes a roller seat 31 fixed to the side wall of the connecting housing 221 and a guiding wheel 32 rotatably connected to the roller seat 31. The guiding wheel 32 is in contact connection with the frame 10. When the telescopic assembly 22 moves up and down, the guiding wheel 32 rotates on the side of the frame 10, playing a role in guiding and reducing friction.

[0043] A further improvement to the above solution is that the lifting assembly 21 includes a lifting motor 211 fixed to the upper end of the frame 10, a second wire reel 212 fixed to the main shaft of the lifting motor 211, and a third steel cable 213 wound around the second wire reel 212. One end of the third steel cable 213 is fixedly connected to the telescopic assembly 22. The lifting motor 211 drives the telescopic assembly 22 to move up and down to adjust the height of the trimming assembly 24.

[0044] A further improvement to the above solution is that the trimming assembly 24 includes a connecting member 241, a driving module 242 fixed to one side of the connecting member 241, and a trimming saw 243 drivingly connected to the driving module 242. The connecting member 241 is hinged to the connecting rod 23, so that the trimming assembly 24 can be rotated to adjust the inclination angle. The driving module 242 drives the trimming saw 243 to rotate to trim the hedge. Specifically, a baffle 244 is fixedly provided at one end of the connecting member 241 facing the trimming saw 243 to prevent branches and leaves from affecting the driving module 242 during the trimming process.
