[0018] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Embodiment:

[0020] Please refer to Figs. 1 to 3 The utility model provides a technical scheme:

[0021] A tree shears on skid steer loader, including body mechanism and shearing mechanism, shearing mechanism installs on the body mechanism. Shearing mechanism can cut the tree.

[0022] The machine body includes a frame 11, a base frame 12, and hydraulic cylinders 13. The frame 11 consists of two vertical and parallel columns, which are fixedly connected by a reinforcing plate. The base frame 12 is fixedly connected to the ground of the frame 11. There are two hydraulic cylinders 13, which are rotatably connected to both ends of the base frame 12. The shearing mechanism is rotatably connected to the output shaft end of the hydraulic cylinders 13. This utility model is mounted on a skid steer loader via the frame 11, and the base frame 12 is used to mount the hydraulic cylinders 13. Compared with traditional shearing machines, the frame 11 consists of two vertical and parallel columns, reducing the need for inclined columns and thus reducing the space occupied. The shearing mechanism is driven by the two hydraulic cylinders 13 to shear trees.

[0023] The shearing mechanism includes a shearing frame 22 and shearing blades 23. The shearing frame 22 is rotatably connected to the output shaft end of the hydraulic cylinder 13, and one end of the shearing frame 22 is rotatably connected to the base frame 12. The shearing blades 23 are bolted to the shearing frame 22. When the hydraulic cylinder 13 is working, it drives the shearing frame 22 at the end to rotate around the fulcrum on the base frame 12, thereby causing the two shearing blades 23 to come into contact and shear.

[0024] Furthermore, both shearing blades 23 are provided with cutting edges, and the cutting edges of the two shearing blades 23 are matched with each other, thereby improving the shearing effect.

[0025] Furthermore, a hydraulic telescopic device is rotatably mounted on the rear side of the frame 11. The output shaft end of the hydraulic telescopic device is rotatably connected to one end of the gripping tooth 21. The gripping tooth 21 is rotatably connected to the frame 11 via a rotating frame. The hydraulic telescopic device can be a telescopic structure such as a hydraulic rod or cylinder, which can drive the gripping tooth 21 to rotate around the fulcrum on the frame 11, thereby encircling the tree to be pruned for auxiliary fixation.

[0026] The working principle of this utility model is as follows: When driving the skid steer loader to the tree to be cut, open the gripper 21, then switch the hydraulic valve to open the cutting mechanism to the maximum. Then drive the skid steer loader forward so that the tree trunk is close to and in the middle of the gripper 21. Then close the gripper 21 to firmly grip the tree trunk. Finally, operate the cutting mechanism to cut the tree trunk until it is broken. After the tree trunk is cut, operate the skid steer loader to slightly lift the utility model. At this time, the cut tree can be transported to the location where it needs to be stacked.

[0027] The improvements of this utility model compared to previous products are as follows:

[0028] The first point is to add a base frame 12 under the frame 11 to provide installation space for increasing the hydraulic cylinder 13, thereby increasing the shearing force;

[0029] Secondly, the structure of frame 11 was optimized. The bulky structure of two main beams and two diagonal braces of a typical tree shearing machine was optimized into two reinforced columns, which reduced the overall volume.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
