Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, a tree pruning device for landscape gardening includes: a trolley 1 for movement; a base 2 mounted on the trolley 1; an operating lever 14 rotatably connected to the base 2; a propulsion mechanism 3 mounted on the operating lever 14, the front end of which is a protective shell 31; a pruning machine 4 slidably connected to the protective shell 31; a guide plate 5 rotatably connected to the base 2, the guide plate 5 being located below the pruning machine 4; a collection box 6 located below the guide plate 5; and a lifting mechanism 7 for pushing the base 2 up and down.

[0024] This device is used for shaping and pruning trees. It can be moved quickly by a trolley 1 to speed up the pruning process, and at the same time, it eliminates the need for manual handling of the electric saw, saving effort.

[0025] A connecting rod 21 is provided on the base 2, located on the upper part of the base 2, and moves together with the base 2. A fixed end of a first telescopic rod 22 is rotatably connected to the connecting rod 21, and the telescopic end of the first telescopic rod 22 is rotatably connected to the rear end of the operating rod 14. The first telescopic rod 22 is used to control the tilt angle of the operating rod 14; when the operating rod 14 needs to tilt forward, the first telescopic rod 22 extends; when it needs to tilt backward, the first telescopic rod 22 shortens.

[0026] The propulsion mechanism 3 is used to adjust the extension and retraction length of the construction machine. For example... Figure 2 As shown, the propulsion mechanism 3 also includes a support plate 32 and a second telescopic rod 33. The support plate 32 is perpendicular to the top of the operating rod 14. The support plate 32 changes angle together with the operating rod 14. The fixed end of the second telescopic rod 33 is fixedly connected to the support plate 32. The telescopic end of the second telescopic rod 33 is located inside the protective shell 31. The rear end of the protective shell 31 has an opening for the telescopic end of the second telescopic rod 33 to enter.

[0027] The protective shell 31 has a blade outlet 311 at the front end, the size of which is the same as the size of the toothed blade of the trimmer 4, and the inner wall of the protective shell 31 has a slide 312.

[0028] The rear end of the pruning machine 4 is connected to the telescopic end of the second telescopic rod 33, the side wall of the pruning machine 4 is slidably connected to the slide rail 312, and the front end of the pruning machine 4 can pass through the blade outlet 311. When it is necessary to prune the tree, first retract the second telescopic rod 33 so that the pruning machine 4 is in the protective shell 31. Then adjust the position of the protective shell 31 so that the front end of the protective shell 31 contacts the position to be pruned. Then start the second telescopic rod 33 to extend forward so that the pruning machine 4 extends out from the blade outlet 311 and prunes the tree. The length of the pruned tree is controlled according to the shape requirements. The second telescopic rod 33 controls the length of the pruning machine 4 by telescopically extending and retracting to ensure that the tree is precisely pruned to the required length.

[0029] The base 2 is equipped with limiting channels 12, which are located on both sides of the base 2 and point vertically upwards. A limiting rod 51 is located at the rear end of the guide plate 5, and the limiting rod 51 is slidably connected to the limiting channel 12. The rear end width of the limiting rod 51 is greater than the width of the limiting channel 12. When not in contact with the tree, the guide plate 5 tilts forward under gravity, and the rear end of the limiting rod 51 contacts the limiting channel 12, preventing the guide plate 5 from rotating further forward. During pruning, the front end of the guide plate 5 is in contact with the underside of the branch to be pruned. At this time, the guide plate 5 rotates backward, and the guide plate 5 is located below the pruning machine 4. The branches and leaves cut by the pruning machine 4 fall into the guide plate 5 and slide downwards. The pruned branches and leaves are directly collected, reducing the subsequent manual cleaning steps and improving work efficiency.

[0030] The base 2 is equipped with a collection port 11, which is located behind the guide plate 5. The pruned tree branches and leaves slide from the guide plate 5 into the collection port 11. The collection port 11 is connected to a collection box 6 below, which is detachably connected to the base 2. When the collection box 6 is full of branches, the collection box 6 can be removed and the branches collected can be disposed of.

[0031] The lifting mechanism 7 is used to adjust the vertical height of the trimmer 4. The lifting mechanism 7 includes a motor 71, a threaded rod 72, and a guide rail 73. The motor 71 is mounted on the trolley 1, the threaded rod 72 is fixedly connected to the output end of the motor 71, and the guide rail 73 is located on the side of the trolley 1. The threaded rod 72 is screwed to the connecting rod 21, and the guide rail 73 passes through the side of the base 2. When the height of the trimmer 4 needs to be adjusted, the motor 71 is started, driving the threaded rod 72 to rotate. The threaded rod 72 drives the base 2 to move up and down, and the side of the base 2 moves up and down along the guide rail 73. The guide rail 73 restricts the base 2 from rotating. When the trimmer 4 reaches the predetermined height, the motor 71 stops rotating.

[0032] The lifting mechanism 7, in conjunction with the movement of the first telescopic rod 22 and the trolley 1, allows the orientation and height of the pruning machine 4 to be quickly adjusted, facilitating precise pruning of trees.

[0033] The trolley 1 is equipped with a control platform 13, which is electrically connected to the first telescopic rod 22, the second telescopic rod 33, the trimmer 4, and the motor 71. The control platform 13 controls the extension and retraction of the first telescopic rod 22 and the second telescopic rod 33, the start and stop of the trimmer 4, and the start, stop, and rotation direction of the motor 71.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
