[0002] Trees in gardens need to be pruned regularly. Proper pruning can achieve the ideal tree shape, improve the landscape effect, control the growth height of the plants, promote leaf division and make the plants grow fuller, and solve the relative balance of water and nutrients between the above-ground and underground parts, reducing water evaporation. On the other hand, pruning dead and diseased branches can effectively reduce the spread of tree diseases and pests. When pruning shrubs, in order to make the shrubs more beautiful.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] like Figures 1 to 3As shown, this utility model provides a forestry tree pruning device, including a base plate 1, movable wheels 2, movable groove 3, movable block 4, movable plate 5, fixed column 6, connecting column 7, pruner 8, and counterweight box 9. The bottom of the base plate 1 is fixedly connected to the top of the movable wheels 2. The movable groove 3 is opened on the top of the base plate 1, and the inner wall of the movable groove 3 is slidably connected to the inner wall of the movable block 4. The top of the movable block 4 is fixedly connected to the bottom of the movable plate 5. The top of the movable plate 5 is fixedly connected to the bottom of the fixed column 6. The back of the connecting column 7 is movably connected to the front of the fixed column 6, and the front side of the surface of the connecting column 7 is fixedly connected to the surface of the pruner 8. The bottom of the counterweight box 9 is fixedly connected to the rear side of the top of the base plate 1. A fixing rod 10 is fixedly connected to the front side of the top of the connecting column 7. A first pulley 11 is fixedly connected to the top of the fixing column 6. A second pulley 12 is fixedly connected to the back of the fixing column 6. A connecting rope 13 is connected to the surface of the second pulley 12. The connecting rope 13 is wrapped around the surface of the second pulley 12. The surface of the connecting rope 13 is in contact with the surface of the first pulley 11. The end of the connecting rope 13 away from the second pulley 12 is fixedly connected to the surface of the fixing rod 10. A lifting assembly 14 is provided on the front of the fixing column 6. A transmission assembly 15 is provided on the top of the moving plate 5.
[0023] refer to Figure 2 The lifting assembly 14 includes a lifting groove 141, which is opened on the front of the fixed column 6. A lifting block 142 is slidably connected to the inner wall of the lifting groove 141. A movable block 143 is fixedly connected to the front of the lifting block 142. The front of the movable block 143 is movably connected to the back of the connecting column 7 through a shaft pin. A lifting rod 144 is movably connected to the top of the inner wall of the lifting groove 141 through a shaft pin. The surface of the lifting rod 144 is threadedly connected to the inner wall of the lifting block 142.
[0024] As a technical optimization of this utility model, by setting up the lifting component 14, when the user needs to adjust the height of the trimmer 8, the lifting groove 141 can restrict the movement direction of the lifting block 142, so that the lifting block 142 can only move up and down inside the lifting groove 141. First, rotate the lifting rod 144, and restrict the movement direction of the lifting block 142 through the lifting groove 141, so that the lifting block 142 will not rotate with the lifting rod 144. As the lifting rod 144 rotates, the lifting block 142 will move up and down. Since the lifting block 142 is fixedly connected to the movable block 143, the fixed block will move up and down with the lifting block 142, which makes it convenient for the user to adjust the height of the connecting column 7, thereby achieving the effect of adjusting the height of the trimmer 8.
[0025] refer to Figure 2The transmission assembly 15 includes a transmission groove 151, which is opened on the top of the movable plate 5. A first motor 152 is fixedly connected to the bottom of the inner wall of the transmission groove 151. The top output end of the first motor 152 passes through to the bottom of the inner wall of the lifting groove 141 and is fixedly connected to the bottom of the lifting rod 144. An air dissipation groove 153 is opened on the outer side of the inner wall of the transmission groove 151.
[0026] As a technical optimization of this utility model, by setting up the transmission component 15, when the user needs the lifting rod 144 to rotate, the first motor 152 is turned on first, and the output end of the first motor 152 rotates to drive the lifting rod 144 to rotate, thereby making the lifting rod 144 rotate automatically. The transmission groove 151 makes it easy for the user to install the first motor 152. As the first motor 152 works, the first motor 152 will generate some heat, and the ventilation groove 153 can quickly dissipate this heat, thereby achieving the effect of automatically rotating the lifting rod 144.
[0027] refer to Figure 3 The left side of the second pulley 12 is movably connected to the first rotating wheel 16 via a pivot pin, and the left side of the fixed column 6 is movably connected to the second rotating wheel 17 via a pivot pin. The surface of the first rotating wheel 16 meshes with the surface of the second rotating wheel 17.
[0028] As a technical optimization of this utility model, by setting a first rotating wheel 16 and a second rotating wheel 17, when the user needs the second pulley 12 to rotate, the second rotating wheel 17 is rotated first. Since the surface of the second rotating wheel 17 meshes with the surface of the first rotating wheel 16, the first rotating wheel 16 will rotate with the second rotating wheel 17. The second rotating wheel 17 can increase the contact area between the user and the second pulley 12, making it easier for the user to rotate the second pulley 12, thereby achieving the effect of assisting the rotation of the second pulley 12.
[0029] refer to Figure 3 A first fixing plate 18 is fixedly connected to the left side of the fixing column 6, and a second fixing plate 19 is fixedly connected to the right side of the fixing column 6. A second motor 20 is fixedly connected to the top of the first fixing plate 18. The output end of the second motor 20 is fixedly connected to the left side of the second rotating wheel 17. A control box 21 is fixedly connected to the top of the second fixing plate 19. The control box 21 is electrically connected to the first motor 152 through wires, and the control box 21 is electrically connected to the second motor 20 through wires.
[0030] As a technical optimization of this utility model, by setting up a first fixing plate 18, a second fixing plate 19, a second motor 20, and a control box 21, when the user needs the first motor 152 to rotate, the control box 21 can transmit an opening electrical signal to the first motor 152. When the user needs the second rotating wheel 17 to rotate, the control box 21 transmits an opening electrical signal to the second motor 20 through a wire. At this time, the second motor 20 is turned on, and the rotation of the output end of the second motor 20 can drive the second rotating wheel 17 to rotate. Furthermore, the first fixing plate 18 and the second fixing plate 19 facilitate the user to install the second motor 20 and the control box 21, thereby achieving the effect of auxiliary control.
[0031] refer to Figure 2 A push rod 22 is fixedly connected to the rear side of the top of the base plate 1. A first touch switch 23 is fixedly connected to the top left side of the push rod 22. A second touch switch 24 is fixedly connected to the top right side of the push rod 22. The first touch switch 23 is electrically connected to the control box 21 through a wire. The second touch switch 24 is electrically connected to the control box 21 through a wire.
[0032] As a technical optimization of this utility model, by setting up a push rod 22, a first touch switch 23, and a second touch switch 24, when the user needs the first motor 152 to rotate, the user presses the first touch switch 23. At this time, the first touch switch 23 transmits an electrical signal to start the first motor 152 through the guide control box 21, which can control the height of the connecting column 7. When the user needs the second motor 20 to rotate, the user presses the second touch switch 24. At this time, the second touch switch 24 transmits an electrical signal to start the second motor 20 through a wire to the control box 21, which can control the rotation of the second pulley 12, making it convenient for the user to adjust the angle of the trimmer 8, thereby achieving the effect of rapid control.
[0033] refer to Figure 2 A through groove 25 is provided at the bottom of the inner wall of the movable groove 3, and an auxiliary groove 26 is provided on the front side of the bottom of the inner wall of the movable groove 3.
[0034] As a technical optimization of this utility model, by setting the through groove 25 and the auxiliary groove 26, as the trimmer 8 is used, some tree leaf debris will enter the interior of the moving groove 3. When too much debris accumulates, it will affect the normal forward and backward movement of the moving block 4. The through groove 25 can move some debris out of the bottom plate 1. When the moving block 4 moves forward and backward, it will push the debris that has not been moved out of the moving groove 3 into the interior of the auxiliary groove 26, thereby making it difficult for debris to accumulate inside the moving groove 3, thus achieving the effect of preventing blockage.
[0035] The working principle and usage process of this utility model are as follows: During use, rotating the second pulley 12 winds the connecting rope 13 onto its surface. As the connecting rope 13 contracts, the fixed rod 10 is pulled upwards, causing the connecting rod to rotate upwards along with the fixed rod 10. This allows the user to easily adjust the angle of the trimmer 8. When the user needs the second rotating wheel 17 to rotate, the control box 21 transmits an activation signal to the second motor 20 via a wire. The second motor 20 then starts, and its output rotation drives the second rotating wheel 17 to rotate. Because the surface of the second rotating wheel 17 meshes with the surface of the first rotating wheel 16, the first rotating wheel 16 rotates along with the second rotating wheel 17, facilitating the user's adjustment of the trimmer 8's angle. When adjusting the height of the shear 8, first turn on the first motor 152. The output of the first motor 152 rotates, driving the lifting rod 144 to rotate. This allows the lifting rod 144 to rotate automatically. The lifting groove 141 restricts the movement direction of the lifting block 142, so that the lifting block 142 can only move up and down inside the lifting groove 141. First, rotate the lifting rod 144, and the lifting groove 141 restricts the movement direction of the lifting block 142, so that the lifting block 142 will not rotate with the lifting rod 144. As the lifting rod 144 rotates, the lifting block 142 will move up and down. Since the lifting block 142 is fixedly connected to the movable block 143, the fixed block will move up and down with the lifting block 142, which makes it easier for the user to adjust the height of the connecting column 7, thereby achieving the effect of auxiliary adjustment.
[0036] In summary, this forestry tree pruning device, by setting up a second pulley 12 and a fixed rod 10, allows the user to rotate the second pulley 12 to wind the connecting rope 13 onto the surface of the second pulley 12. As the connecting rope 13 contracts, the fixed rod is pulled upward, and the connecting rod will flip upward along with the fixed rod 10. This makes it easier for the user to adjust the angle of the pruner 8. This solves the problem that while the tree pruning device allows the user to easily adjust the position of the fixed rod forward and backward, it does not have a structure for adjusting up and down, resulting in a fixed pruning height and an inability to adjust the angle of the cutting device, which limits its functionality.
