[0045] like Figure 2-5 As shown, the trimmer 3 includes a housing 301, a trimming unit 302, a protection unit 303 and an air jet unit 10. The housing 301 can establish a connection relationship between the trimming unit 302 and the protection unit 303.

[0046] The protection unit 303 is located on both sides of the trimming unit 302 , and both the protection unit 303 and the trimming unit 302 are connected to the housing 301 .

[0047] like Figure 6 As shown, the trimming unit 302 includes a fixed toothed knife 302-1, a movable toothed knife 302-2, an L-shaped connecting frame 302-3, a connecting piece 302-4, a rotating motor 302-5 and an eccentric shaft 302-6. The shell 301 opens a trimming port 6, which is connected to the inside of the shell 301.

[0048] A fixed tooth knife 302-1 is arranged on one side of the trimming opening 6 of the shell 301, and the fixed tooth knife 302-1 is detachably fixedly connected to the shell 301. A movable tooth knife 302-2 is arranged on the trimming opening 6, and the movable tooth knife 302-2 is movably matched with the fixed tooth knife 302-1. The connecting frame 302-3, the connecting piece 302-4, the rotating motor 302-5 and the eccentric shaft 302-6 are all located inside the shell 301, and the movable tooth knife 302-2 is detachably fixedly connected to the connecting frame 302-3.

The output shaft part of the eccentric shaft 302-6 is slidably matched with the connecting frame 302-3 in the movable opening 7.

[0049] The output end of the rotating motor 302-5 drives the eccentric shaft 302-6 to rotate as a whole. Since the output shaft portion of the eccentric shaft 302-6 is connected to the connecting frame 302-3 in the movable opening 7, and the elliptical movable opening 7 can limit the movable range of the connecting piece 302-4, the shaft portion of the eccentric shaft 302-6 can move back and forth longitudinally in the movable opening 7. Since the connecting frame 302-3 and the housing 301 are hinged through the connecting piece 302-4, the eccentric shaft 302-6 can move back and forth longitudinally in the movable opening 7. While the shaft portion of 2-6 moves longitudinally back and forth in the movable opening 7, the connecting frame 302-3 swings left and right in the shell 301 with the connecting piece 302-4 as the axis, thereby indirectly causing the movable tooth knife 302-2 to move left and right, while the fixed tooth knife 302-1 and the shell 301 always maintain a fixed position, so the tooth knife portion of the fixed tooth knife 302-1 and the tooth knife portion of the movable tooth knife 302-2 are in an intermittent staggered state, thereby realizing a pruning action to prune the branches of trees.

[0050] The protection unit 303 includes a first electric slide rail assembly 303-1, a second electric slide rail assembly 303-2, a first track wheel 303-3 and a second track wheel 303-4. The first groove 4 and the second groove 5 are respectively formed at two ends of one side of the housing 301.

[0051] The first groove 4 is provided with a first electric slide rail group 303-1, the slide rail part of the first electric slide rail group 303-1 is connected to the shell 301, the movable part of the first electric slide rail group 303-1 is connected to the first track wheel 303-3, the first track wheel 303-3 and the shell 301 are slidably matched through the first electric slide rail group 303-1, and the first groove 4 has two states of storage and presentation relative to the first track wheel 303-3.

[0052] The second groove 5 is provided with a second electric slide rail group 303-2, the slide rail part of the second electric slide rail group 303-2 is connected to the shell 301, the movable part of the second electric slide rail group 303-2 is connected to the second track wheel 303-4, the second track wheel 303-4 and the shell 301 are slidably matched through the second electric slide rail group 303-2, and the second groove 5 has two states of storage and presentation relative to the second track wheel 303-4.

[0053] When the first electric slide rail assembly 303-1 and the second electric slide rail assembly 303-2 drive the first track wheel 303-3 and the second track wheel 303-4 to be stored in the first groove 4 and the second groove 5 respectively, the trimming unit 302 can follow the movement of the vehicle body 1 to trim the tree branches. At this time, a cover 9 is provided outside the first groove 4 and the second groove 5, and the cover 9 is connected to the housing 301. The cover 9 can shield the first groove 4, the second groove 5 and the structure inside the first groove 4 and the structure inside the second groove 5, so as to prevent leaves or dust from entering the first groove 4 and the second groove 5 when the trimming unit 302 is working.

[0054] like Figure 7-9 As shown, when the cover 9 is disassembled from the housing 301, and the first electric slide rail group 303-1 and the second electric slide rail group 303-2 respectively drive the first track wheel 303-3 and the second track wheel 303-4 in the first groove 4 and the second groove 5 to be in the display state, the protection unit 303 will protrude from the trimming unit 302, and at this time, the first track wheel 303-3 and the second track wheel 303-4 of the trimming unit 302 are abutted against the outside of the fence, and can move with the movement of the vehicle body 1 outside the fence, ensuring that a safe distance is maintained between the trimming unit 302 and the fence, and preventing the trimming unit 302 from interfering with or colliding with the fence due to the instability of the moving route of the vehicle body 1. Among them, the outside of the first track wheel 303-3 and the outside of the second track wheel 303-4 are both provided with a protection pad 8. The protection pad 8 can prevent the first track wheel 303-3 or the second track wheel 303-4 from causing damage to the fence when moving on the surface of the fence.

[0055] The jet unit 10 includes a fan 1001, a ventilation pipe 1002, an air cavity 1003 and several air nozzles 1004. The air cavity 1003 is arranged at the outer edge of the trimming opening 6 of the shell 301, and the air cavity 1003 is connected to the shell 301. Several air nozzles 1004 are arranged on the side of the wind cavity 1003 away from the shell 301. The ventilation pipe 1002 is arranged on the side of the wind cavity 1003 adjacent to the shell 301. The wind cavity 1003 is connected to one end of the ventilation pipe 1002, and the fan 1001 is arranged on the other end of the ventilation pipe 1002 through the shell 301. The fan 1001 is connected to the shell 301, and the air outlet end of the fan 1001 is connected to the ventilation pipe 1002. The function of the jet unit 10 is to generate strong wind through the fan 1001, send the strong wind into the wind cavity 1003 through the ventilation pipe 1002, and then release high-speed airflow from the jet nozzle 1004 to remove weeds, leaf fragments and other debris hanging on the surface of the fixed tooth knife 302-1 and the movable tooth knife 302-2 during the pruning operation.

[0056] A solar panel 11 is disposed outside the housing 301, and the solar panel 11 is electrically connected to the first electric rail assembly 303-1, the second electric rail assembly 303-2, the first track wheel 303-3, the second track wheel 303-4, the rotating motor 302-5, and the fan 1001. By being electrically connected to the first electric rail assembly 303-1, the second electric rail assembly 303-2, the first track wheel 303-3, the second track wheel 303-4, the rotating motor 302-5, and the fan 1001, the solar panel 11 can directly or indirectly provide the required electrical energy to these components to support the operation and function of the tree trimming vehicle.

[0057] The implementation principle of the utility model tree pruning vehicle is as follows:

[0058] When the pruning vehicle is used to directly prune tree branches, the rotating motor 302-5 is started, so that the output end of the rotating motor 302-5 drives the eccentric shaft 302-6 to rotate as a whole. Since the output shaft portion of the eccentric shaft 302-6 is connected to the connecting frame 302-3 in the movable opening 7, and the elliptical movable opening 7 limits the movable range of the connecting member 302-4, the shaft portion of the eccentric shaft 302-6 can move back and forth longitudinally in the movable opening 7. Since the connecting frame 302-3 and the housing 301 are hinged through the connecting member 302-4, the eccentric shaft 302-6 can move back and forth longitudinally in the movable opening 7. While the shaft portion of 02-6 moves longitudinally back and forth in the movable opening 7, the connecting frame 302-3 swings left and right in the shell 301 with the connecting piece 302-4 as the axis, thereby indirectly causing the movable tooth knife 302-2 to move left and right, while the fixed tooth knife 302-1 and the shell 301 always maintain a fixed position, so the tooth knife portion of the fixed tooth knife 302-1 and the tooth knife portion of the movable tooth knife 302-2 are in an intermittent staggered state, thereby realizing the pruning action, and then the vehicle body 1 is started and allowed to move along the track of the required tree pruning, thereby pruning the tree branches.

[0059] When the pruning vehicle is used to prune tree branches growing outside the fence, the first electric slide group 303-1 and the second electric slide group 303-2 are first started, so that the first electric slide group 303-1 and the second electric slide group 303-2 respectively drive the first track wheel 303-3 and the second track wheel 303-4 to extend out of the first groove 4 and the second groove 5, and the first track wheel 303-3 and the second track wheel 303-4 are abutted against the outside of the fence, and the rotating motor 302-5, the vehicle body 1, the first track wheel 303-3 and the second track wheel 303-4 are started, so that while the pruning unit 302 performs the pruning movement of the upper section, the first track wheel 303-3 and the second track wheel 303-4 will move outside the fence with the movement of the vehicle body 1, ensuring that a safe distance is maintained between the pruning unit 302 and the fence, preventing the pruning unit 302 from interfering with or colliding with the fence due to the unstable moving route of the vehicle body 1.

[0060] During the process of pruning tree branches, if weeds, leaf fragments or other debris are hanging on the surface of the fixed tooth blade 302-1 and the movable tooth blade 302-2, the fan 1001 can be turned on to generate strong wind. The strong wind enters the wind cavity 1003 through the ventilation pipe 1002, and then releases a high-speed airflow from the air nozzle 1004. The high-speed airflow can blow away the weeds, leaf fragments or other debris hanging on the surface of the fixed tooth blade 302-1 and the movable tooth blade 302-2, preventing these debris from affecting the pruning effect and ensuring the quality and efficiency of pruning.

[0061] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
