In the process of urbanization, it is particularly important to improve the urban ecological environment. Garden plants, with their own ecological functions and application functions in noise reduction, dust removal, beautification and isolation, continuously promote the expansion of urban greening, and also promote the continuous development of garden art. Since the 1950s, hedge isolation belt pruning equipment has undergone an evolution from manual scissors to portable scissors, and then to motorized pruning equipment with autonomous power.

This method has high labor cost and cannot control the quality of pruning, has low automation degree and poor environmental adaptability. For example, the existing vehicle-mounted hedge pruning machine has low working efficiency on the highway with heavy traffic, and needs multiple people to assist in completing the work. For example, in garden design, manual or semi-manual pruning methods are low in efficiency and cannot guarantee the uniformity of standards.

[0035] It further includes a lifting mechanism 5 and a cutting mechanism 6. The lifting mechanism 5 is installed on top of the support frame 3, and the cutting mechanism 6 is installed on one side of the lifting mechanism 5. The worm 53 in the lifting mechanism 5 rotates to drive the worm gear 575 to lift and lower in the vertical direction. The connecting shaft 574 is driven to rotate by the rotating motor 571, so that the rotating gear 576 pushes the rack 552 to move horizontally. The direction of the cutting mechanism 6 is adjusted through the movement of the lifting mechanism 5 in two directions, horizontal and vertical. With the rotation of the coupling block 6353, multiple cutters 64 sequentially perform reciprocating telescopic movements.

[0036] As Figure 2 shown, the lifting mechanism 5 includes a mounting frame 51, a connecting through hole 511, a fixed rod 52, a worm 53, a horizontal slider 54, a sliding frame 55, a steering gear 56 and a rotating component 57. The mounting frame 51 is installed on top of the support frame 3. The vertical cross-sectional shape of the mounting frame 51 is set as a "hui" character shape. The "hui" character structure is beneficial to enhancing the strength of the entire lifting mechanism 5, so as to ensure that during the movement process, the entire mounting frame 51 remains stable, thereby further improving the accuracy of the lifting mechanism 5 and obtaining a more beautiful trimming result. A connecting through hole 511 is opened on the lower surface of the mounting frame 51. The connecting through hole 511 is used to connect the drive motor 2 and the worm 53. A frame sliding groove 512 is opened on the side surface of the mounting frame 51. The frame sliding groove 512 is used to install the rotating component 57 to slide therein. The fixed rod 52 is installed between the upper and lower surfaces inside the mounting frame 51. The fixed rod 5,2 is used to provide a limit for the sliding path of the horizontal slider 54. There are 2 fixed rods 52. There are 2 worms 53. One of the worms 53 is installed on the inner surface of the mounting frame 51, and the worm 53 is located directly above the connecting through hole 511. The lower end of the worm 53 is connected to the drive motor 2. The worm 53 is used to drive the worm gear 575 to perform vertical displacement. The horizontal slider 54 is installed on the surface of the fixed rod 52. The horizontal slider 54 remains horizontal during the movement process, and the horizontal slider 54 is used to adjust the vertical height of the sliding frame 55. The sliding frame 55 is installed on the side surface of the horizontal slider 54. The sliding frame 55 is horizontally displaced under the drive of the rotating component 57 and is connected to the cutting mechanism 6. The steering gear 56 is installed at the upper end of the side surface of the worm 53. There are 2 steering gears 56. The 2 steering gears 56 are meshed with each other. When the drive motor 2 drives one worm 53 to rotate, the worm 53 on one side will rotate in the opposite direction through the steering gear 56. The rotating component 57 is installed in the frame sliding groove 512. The rotating component 57 moves up and down under the drive of the worm gear 575, and the internal rotating motor 571 can be controlled to rotate through the remote control box 7 to drive the sliding frame 55 to move horizontally.

[0037] The driving motor 2 is controlled by the remote control box 7, and drives the worm 53 to rotate through the connecting hole 511. The steering gears 56 at the top of the worm 53 will mesh with each other to drive the other worm 53 to rotate. The rotation directions of the two worms 53 are opposite. Thus, under the operation principle of the worm gear 575 worm 53, the rotating assembly 57 will rise or fall in the vertical direction, depending on the rotation direction of the driving motor 2. The rotating assembly 57 passes through the horizontal sliding block 54, so that the horizontal sliding block 54 can slide on the fixed rod 52. The rotating assembly 57 receives the instructions from the remote control box 7, and the internal components rotate to drive the sliding frame 55 to slide horizontally on the horizontal sliding block 54, so as to realize the position adjustment of the cutting assembly 63. In work, the driving motor 2 and the rotating assembly 57 receive the instructions provided by the remote control box 7, so as to realize the continuous position change. Thus, the shrubs are trimmed in different shapes.

[0038] As shown in Figure 3 The horizontal sliding block 54 includes a sliding bar 541, a sliding hole 542, a clamping block 543, a clamping groove 544, a rotating hole 545, a fixed bar 546, and a round hole 547. The sliding bar 541 is installed on the side of the horizontal sliding block 54, and is used to install the horizontal sliding block 54. The sliding hole 542 is arranged at both ends of the sliding bar 541, and is used to cooperate with the fixed rod 52. The clamping block 543 is installed above the sliding bar 541, and is used to cooperate with the clamping sliding frame 55. The vertical section of the clamping block 543 is L-shaped, and the L-shaped clamping block 543 can form the clamping groove 544 with the horizontal sliding block 54. The clamping groove 544 is arranged between the clamping block 543 and the sliding bar 541, and is used to install the rack 552. The rotating hole 545 is arranged at the intersection of the center line of the horizontal sliding block 54. The rotating hole 545 arranged at the center can make the lifting effect of the rotating assembly 57 better, and the torque more uniform. The fixed bar 546 is installed on the sliding bar 541 on the other side, and the vertical section of the fixed bar 546 is rectangular. The round hole 547 is arranged on the side of the fixed bar 546, and is used to install the sliding rod 556 and make it slide therein.

[0039] Since the worm gear 575 moves under the driving of the worm 53, the connecting shaft 574 also moves up and down. The connecting shaft 574 is rotationally connected with the rotating hole 545, so that the horizontal sliding block 54 slides on the fixed rod 52 through the sliding hole 542, and the sliding frame 55 is brought to realize synchronous motion through the round hole 547 and the clamping groove 544.

[0040] As shown in Figure 4As shown, the sliding frame 55 includes a limiting baffle 551, a rack 552, a mounting block 553, a connecting block 554, a ball hinge groove 555, and a sliding rod 556; the two sides of the sliding frame 55 are provided with the limiting baffle 551, which is used to limit the lateral displacement dimension of the sliding frame 55, the rack 552 is installed between the limiting baffles 551, the rack 552 is clamped in the clamping groove 544, and the rack 552 is used to drive the sliding frame 55 to move laterally under the driving of the rotating assembly 57, the mounting block 553 is installed on the upper surface of the limiting baffle 551, the mounting block 553 is used to install the connecting block 554, the connecting block 554 is installed on the upper surface of the mounting block 553, the ball hinge groove 555 is arranged at the center of the upper surface of the connecting block 554, the ball hinge groove 555 is used to install the ball hinge rod 65 in the cutting mechanism 6, the ball hinge groove 555 is provided in the shape of a ball segment, specifically in the shape of a ball segment larger than a hemisphere, so as to wrap one end of the entire ball hinge rod 65, thereby improving the connection stability, and the sliding rod 556 is installed at the other end of the limiting baffle 551, the sliding rod 556 is used to strengthen the stability between the sliding frame 55 and the horizontal sliding block 54, and the radius of the sliding rod 556 is the same as that of the circular hole 547, so that the sliding rod 556 can easily slide in the circular hole 547.

[0041] The sliding rod 556 in the sliding frame 55 is limited in the circular hole 547, the rack 552 is clamped in the clamping groove 544, so that the sliding frame 55 moves with the horizontal sliding block 54, and the rack 552 moves in the horizontal direction under the driving of the rotating assembly 57, thereby driving the ball hinge groove 555 opened on the connecting block 554 to adjust the ball hinge rod 65, achieving the effect of changing the direction of the cutting mechanism 6.

[0042] As shown in the figure, Figure 5 The rotating assembly 57 includes a rotary motor 571, a square block 572, a limiting sliding block 573, a connecting shaft 574, a worm gear 575, and a rotating gear 576; the rotary motor 571 is installed on the side surface of the mounting frame 51, the square block 572 is installed on the side surface of the rotary motor 571, the limiting sliding block 573 is installed on the horizontal two sides of the square block 572, the vertical cross section of the limiting sliding block 573 is isosceles trapezoidal, the isosceles trapezoidal limiting sliding block 573 can improve the stability of the rotating assembly 57 installed on the mounting frame 51, the connecting shaft 574 is installed at the center of the square block 572 to balance the entire force moment, the worm gear 575 is installed on the outer surface of the connecting shaft 574, and the worm gear 575 is used to drive the connecting shaft 574 to rise under the driving of the worm 53, and the rotating gear 576 is installed at one end of the connecting shaft 574, and the rotating gear 576 is used to drive the rack 552 to move.

[0043] The worm wheel 575 is lifted or lowered by the rotation force of the two worm gears 53, and drives the whole rotating assembly 57 to rise and fall through the connecting shaft 574. The rotating motor 571 is controlled by the remote control box 7 to rotate forward or reverse, thereby driving the gear 576 to drive the engaged rack 552 to move in the horizontal direction.

[0044] As shown in Figure 7 and Figure 8 , the cutting mechanism 6 includes clamping rods 61, limiting rods 62, cutting assemblies 63, cutters 64, ball joint rods 65 and universal joints 66. The two clamping rods 61 are coaxially installed on the upper and lower surfaces of the mounting frame 51 respectively. The limiting rod 62 is installed on the upper surface of the lower part of the mounting frame 51. The limiting rod 62 is symmetrically arranged along the axis of the clamping block 543, so as to limit the two sides of the cutting assembly 63. The cutting assembly 63 is installed in the middle of the clamping rod 61. The cutting assembly 63 is used to drive the cutter 64 to cut the shrubs. One end of the ball joint rod 65 is installed in the ball joint groove 555. The ball joint rod 65 is used to rotate under the drive of the lifting mechanism 5. The length of the ball joint rod 65 is equal to the distance from the cutting assembly 63 to the connecting block 554, so that when the lifting mechanism 5 rotates to adjust the ball joint rod 65 and the cutting assembly side to be perpendicular, it can continue to rotate normally, thereby ensuring the rotation freedom of the cutting mechanism 6. The universal joint 66 is installed at the other end of the ball joint rod 65. The universal joint 66 is used to keep the cutting assembly 63 and the sliding frame 55 connected during rotation. The surface of the clamping rod 61 is provided as a contact surface 611. The side surface of the limiting rod 62 close to the clamping rod 61 is provided as a limiting surface 621. The contact surface 611 and the limiting surface 621 are provided as arc surfaces, and the curvature values of the contact surface 611 and the limiting surface 621 are the same, so that the cooperating block 634 can have a larger freedom to rotate.

[0045] The ball joint rod 65 adjusts the direction of the cutting assembly 63 through the universal joint 66. The cutting assembly 63 is clamped and limited by the clamping rod 61 and the limiting rod 62 during rotation, so that it can only move freely within a certain angle range.
