[0002] Forest tending and pruning is an important part of forest tending technology. It plays an important role in improving tree growth, improving tree quality and increasing tree yield.

On the inner surface, the second saw wheel 114 is rotatably connected to a guide plate 117, and the side of the guide plate 117 away from the second saw wheel 114 is rotatably connected to the first saw wheel 112, and a saw chain 101 is arranged on the surface of the guide plate 117 and in sequence around the second saw wheel 114 and the first saw wheel 112, and a saw chain rotating rod 113 is rotatably installed on the surface of the guide plate 117, and a pushing and rotating hydraulic cylinder 102 is rotatably installed on the surface of the saw chain rotating rod 113, and a moving rod 103 is rotatably installed on one end of the pushing and rotating hydraulic cylinder 102, and a rotating push rod 104 is rotatably installed on one end of the moving rod 103, and one end of the rotating push rod 104 is rotatably installed on the connecting push rod 105, and a saw chain motor 109 is fixedly installed on the right side surface of the second saw wheel 114.

[0037] A limiting moving wheel 115 is fixedly mounted on the surface of the saw chain motor 109 . The limiting moving wheel 115 is slidably disposed on the movable rod 3 through a limiting sliding groove. A rotating stopper 110 is fixedly mounted on the right end surface of the movable rod 3 .

[0038] The outer surface of the linkage rod 108 is rotatably mounted with a clamping device 2, and the clamping device 2 includes: a front end clamping rod 201, a clamping fixed rod 202, a lower end clamping sliding block 203, a clamping spring 204 and an upper end clamping sliding block 205, one end of the two clamping fixed rods 202 are both rotatably mounted on the outer surface of the linkage rod 108, the surface of the front end clamping rod 201 is rotatably mounted on the inner surface of the clamping fixed rod 202, the surface of the clamping spring 204 is arranged on the outer surfaces of the front end clamping rod 201 and the clamping fixed rod 202, and the two clamping fixed rods 202 are slidably mounted on the upper and lower sides of the movable rod 3 respectively through the lower end clamping sliding block 203 and the upper end clamping sliding block 205 in turn.

[0039] Wherein, the sawing device 1 will push the rotary hydraulic cylinder 102 to push the guide plate 117 to move when the push rod 111 is not compressed, and the saw chain motor 109 drives the guide plate 117 to rotate;

[0040] The movable wheel 115 is restricted to move within the track set on the right side of the movable rod 3 to ensure the position rotation of the saw chain motor 109;

[0041] The push and pull of the rotating hydraulic cylinder 102 and the saw chain motor 109 will drive the guide plate 117 to rotate 180 degrees for sawing.

[0042] The working principle of a forest tending and pruning device provided by the present invention is as follows:

[0043] First, the device is moved to the bottom of the tree that needs to be pruned. The worker holds the device and aligns the pruning end of the device with the branch that needs to be pruned. Then the saw chain motor 109 is started, and the device is pressed against the branch to compress the pushing rod 111. The pushing rod 111 drives the linkage rod 108, and then drives the two connected clamping and fixing rods 202. The clamping and fixing rods 202 move backward while rotating, and the two front clamping rods 201 move toward the middle to clamp the branch, so that the branch is in contact with the pushing rod 111 and continuously compressed. The second saw wheel 114, the first saw wheel 112 and the saw chain 101 move toward the direction of the branch to saw off the branch. When it moves to the front end limit position, the rotating hydraulic cylinder 102 is pushed to move, driving the saw chain 101 to rotate to completely saw off the branch. After sawing off, the device is closed and the operation is repeated to prune the next branch.

[0044] Compared with the related art, the forest tending and pruning device provided by the present invention has the following beneficial effects:

[0045] The worker holds the device, starts the sawing device 1 and moves it toward the branch in coordination with the sliding extension rod 4. When it moves to the front end limit position, the rotating hydraulic cylinder 102 is pushed to operate, and the clamping device 2 clamps the branch, making the sawing device 1 more stable and convenient when sawing. At the same time, the saw chain 101 rotates to completely saw off some thick branches, reducing certain usage restrictions.

[0046] Second embodiment:

[0047] Please refer to Figure 7 and Figure 8 Based on the forest tending and pruning device provided in the first embodiment of the present application, the second embodiment of the present application provides another forest tending and pruning device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0048] Specifically, the difference of the forest tending and pruning device provided in the second embodiment of the present application is that the outer surface of the sliding extension rod 4 is provided with a sliding telescopic shell 6, and the sliding stopper 5 is fixedly mounted on the sliding telescopic shell 6.

[0051] In actual use, the limiting end of the sliding block 5 is arranged in the sliding groove of the sliding extension rod 4, and the protrusion of the sliding block 5 will limit the position of the sliding extension rod 4;

[0052] When the sliding motor 1903 is started, the screw sliding block 1901 will drive the sliding extension rod 4 to extend.

[0053] The working principle of a forest tending and pruning device provided by the present invention is as follows:

[0054] The worker uses a handheld device to aim the trimming end of the device at the branch, starts the sliding motor 1903, extends the sliding extension rod 4 to the root of the branch through the screw sliding block 1901, continuously squeezes the pushing rod 111, and then pushes out the sawing device 1 and the clamping device 2, clamps the branch to saw and trim the branch.

[0055] Compared with the related art, the forest tending and pruning device provided by the present invention has the following beneficial effects:

[0056] By aiming the device at the tree branch, the sliding motor 1903 drives the screw sliding block 1901 to extend the sliding extension rod 4 and then push out the sawing device 1 and the clamping device 2 to saw the branch, and prune the higher places that cannot be pruned, reducing the labor of workers.
