[0033] In another way, two-dimensional movement can also be completed by using front and rear wheels.

[0035] Furthermore, it further includes a vertical cutting unit 3 located on the base 1, and the vertical cutting unit 3 is used for vertically cutting the tea trees.

[0036] It also includes a height adjustment seat 4, which is located above the base 1. A height adjustment mechanism 5 is provided on the base 1 and is connected to the height adjustment seat 4. The height adjustment mechanism 5 is used to adjust the height of the height adjustment seat 4 relative to the base 1. The horizontal cutting unit 6 is connected to the height adjustment seat 4. Thus, by adjusting the height adjustment seat 4, the height of the horizontal cutting unit 6 can be adjusted. The horizontal cutting unit 6 is used for horizontally cutting the tea trees, and further cooperates with the vertical cutting unit 3 to meet the cutting requirements of multiple angles and directions. And, the horizontal cutting unit 6 and the vertical cutting unit 3 are mutually offset in the front-back direction of the base 1, so as to avoid interference between the two. At the same time, by adjusting the height of the horizontal cutting unit 6, the pruning requirements of tea trees of different heights can be adapted.

[0037] Preferably, the numbers of both the horizontal cutting unit 6 and the vertical cutting unit 3 are 2 and they are symmetrically arranged along the base 1, so as to improve the overall pruning efficiency, increase the overall weight at the same time, and adjust the center of gravity, thereby avoiding tipping during the cutting process.

[0038] Preferably, power units 7 are provided on both the base 1 and the height adjustment seat 4 and are respectively connected to the two horizontal cutting units 6 / vertical cutting units 3. The power unit 7 includes a pruning motor 8 and a transmission rod 9. Both ends of the transmission rod 9 are respectively connected to the two-side horizontal cutting units 6 / vertical cutting units 3. A driving gear 10 is provided at the output end of the pruning motor 8, and a driven gear 11 is provided on the transmission rod 9 and cooperates with the driving gear 10.

[0039] In this embodiment, the driving gear 10 is connected to the driven gear 11 through a belt. In another way, the driving gear 10 can also be directly meshed with the driven gear 11, or a speed reduction mechanism or the like can be provided between the driving gear 10 and the driven gear 11 to complete the linkage drive.

[0040] During use, the pruning motor 8 drives the driving gear 10 to rotate, and then drives the transmission rod 9 to rotate through the driven gear 11, so that the power at both ends of the transmission rod 9 is transmitted to the two-side horizontal cutting units 6 or vertical cutting units 3, so as to realize the simultaneous drive of a single drive source for the two horizontal cutting units 6 or vertical cutting units 3.

[0041] Preferably, both the horizontal cutting unit 6 and the vertical cutting unit 3 include a power seat 12, a fixed knife 13 and a movable knife 14. The power seats 12 corresponding to the horizontal cutting unit 6 and the vertical cutting unit 3 are respectively fixedly connected to the base 1 and the height-adjusting seat 4. The fixed knife 13 is fixedly connected to the base 1, and the movable knife 14 is slidably arranged relative to the fixed knife 13. Specifically, a groove portion is provided on the fixed knife 13 along the length direction, and the movable knife 14 is connected to the groove portion by bolts, so that the screw rod moves in the groove portion to realize the sliding of the movable knife 14 relative to the fixed knife 13. A first transmission mechanism and a second transmission mechanism are respectively provided in the power seats 12 corresponding to the horizontal cutting unit 6 and the vertical cutting unit 3, and both the first transmission mechanism and the second transmission mechanism are used to drive the movable knife 14 to reciprocate along the length direction of the fixed knife 13.

[0042] In another way, both the horizontal cutting unit 6 and the vertical cutting unit 3 include an outer casing. One end of the outer casing is open and sleeved outside the fixed knife 13 and the movable knife 14, so as to play an isolation and protection role for the blades when the blades are not in use. And when in use, by removing the outer casing, cutting can be realized through the fixed knife 13 and the movable knife 14.

[0043] Specifically, in this embodiment, both ends of the transmission rod 9 extend into the power seat 12 and are connected to the first transmission mechanism / the second transmission mechanism, so as to provide a power source by rotating the transmission rod 9.

[0044] Preferably, a first cutting blade group is fixedly provided on one side of the fixed knife 13. The first cutting blade group includes a plurality of first cutting blades 15 arranged along the length direction of the fixed knife 13. The fixed knife 13 is provided with a second cutting blade group arranged in a staggered manner corresponding to the first cutting blade group. The second cutting blade group includes a plurality of second cutting blades 16. The plurality of second cutting blades 16 correspond to the first cutting blades 15 one by one, and the movable knife 14 is detachably connected to the tails of the plurality of second cutting blades 16 in sequence.

[0045] Through the detachable connection of the movable knife 14, it is convenient to replace the second cutting blade 16 after it is damaged, so as to facilitate long-term use and reduce the replacement cost.

[0046] Furthermore, the first cutting blade 15 is fixed to the fixed knife 13 by a plurality of bolts, so as to further reduce the use cost and achieve the single replacement of the first cutting blade 15 or the second cutting blade 16.

[0047] Preferably, at least two positioning holes 17 are provided at the tail of the second cutting blade 16, and the movable knife 14 is respectively connected to the two positioning holes 17 by bolts to fix the second cutting blade 16 relative to the movable knife 14. By means of the positioning holes 17, it is convenient to disassemble and assemble the second cutting blade 16.

[0048] Preferably, both the first transmission mechanism and the second transmission mechanism include a power column 18, which is rotatably arranged in the power seat 12. Specifically, the power column 18 is a screw rod. One end of the movable knife 14 extends into the power seat 12 and is provided with a driving block 19. The inner wall of the power seat 12 abuts against and restricts the driving block 19 to rotate. The driving block 19 is provided with a connecting hole 20 and is threadedly connected to the power column 18.

[0049] Referring to Figure 4 , in the first transmission mechanism, one end of the transmission rod 9 extends into the power seat 12 and is directly fixed to the power column 18. Then, by rotating the transmission rod 9, the power column 18 can be driven to rotate. Due to the abutting restraint between the driving block 19 and the inner wall of the power seat 12, the driving block 19 can be driven to move back and forth along its own axis by the rotation of the power column 18, thereby realizing the forward and backward driving of the movable knife 14. The threaded connection method can ensure the rigid driving of the movable knife 14 to ensure the shearing force of the movable knife 14.

[0050] Referring to Figure 5 , in the second transmission mechanism, one end of the transmission rod 9 extends into the power seat 12 and is provided with a first bevel gear 21. At the same time, the bottom of the power column 18 is provided with a second bevel gear 22 that cooperates with the first bevel gear 21, so as to achieve the driving effect through the meshing of the first bevel gear 21 and the second bevel gear 22.

[0051] Preferably, the height adjustment mechanism 5 includes a height adjustment motor 23 and a height adjustment column 29. The height adjustment seat 4 is provided with a height adjustment hole 24. The height adjustment column 29 is a screw rod and passes through the height adjustment hole 24 and is threadedly connected to the height adjustment seat 4. The base 1 is provided with a limiting rod 25, and the limiting rod 25 passes through the height adjustment seat 4 to limit the height adjustment seat 4 from moving along the length direction of the limiting rod 25.

[0052] In this embodiment, a worm and worm gear structure is formed between the output end of the height adjustment motor 23 and the height adjustment column 29 to achieve the driving effect. By this method, the driving force can be greatly improved to ensure the lifting effect of the height adjustment seat 4.

[0053] During use, the height adjustment motor 23 drives the height adjustment column 29 to rotate. Due to the limitation of the height adjustment seat 4 by the limiting rod 25, the height adjustment seat 4 can move up and down along the length direction of the height adjustment column 29, thereby realizing the height adjustment of the height adjustment seat 4.

[0054] Preferably, a shock-absorbing spring 26 is wound around the limiting rod 25. Both ends of the shock-absorbing spring 26 abut against the height adjustment seat 4 and the base 1 respectively. The shock-absorbing spring 26 is used to drive the height adjustment seat 4 to move away from the base 1.

[0055] The setting of the shock-absorbing spring 26 can greatly reduce the impact of the height adjustment seat 4 during use to improve the overall reliability.

[0056] Preferably, a generator 27 is provided on the base 1. The generator 27 is connected to the height-adjusting motor 23 and the trimming motor 8 through wires to provide power for them. A display component 28 is provided at the front end of the base 1, and the operator can display the operating state of the device through the display component 28.

[0057] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention.
