[0027] In this embodiment, the motor 2 51 outputs torque, which can drive the coaxially connected bidirectional screw rod 1 52 to rotate. At this time, the two ends of the bidirectional screw rod 1 52 will transmit information to the adjusting plates 4 on both sides to drive the adjusting plates 4 to move axially along the sliding shaft 53 inside the sliding groove 54. The adjusting plates 4 on both sides can approach or move away from each other, wherein the sliding shaft 53 can provide support and axial limitation for the adjusting plates 4.

The counterweight block 17 can increase the weight of the chassis 1 to balance the center of gravity of the equipment and prevent the equipment from tipping over.
[0032] Working principle: Motor 2 51 can drive the coaxially connected bidirectional screw rod 1 52 to rotate. At this time, the two ends of the bidirectional screw rod 1 52 will transmit to the adjusting plates 4 on both sides to drive the adjusting plates 4 to move axially along the sliding shaft 53 in the sliding groove 54. The adjusting plates 4 on both sides can approach or move away from each other, so that the blades 2 14 thereon move relative to each other, so that the distance between the two blades 2 14 is equal to the width of the green belt to be cut. At the same time, when the output shaft of motor 5 713 rotates, the synchronous wheel 712 installed thereon rotates accordingly, and transmits to the synchronous wheel 712 on the bidirectional screw rod 2 7 through the synchronous belt 711 to drive the bidirectional screw rod 2 7 to rotate, thereby driving the two sliding blocks 8 and the blades 12 on both sides to move axially along the limiting rod 9, that is, move relative to each other or move away from each other, to trim the narrow and long green belt. The distance between the two blades 2 14 is equal to the width of the green belt to be cut. The three blades 12 above are side by side, and the driving motor 3 11 When the motor four 13 drives the blade one 12 and the blade two 14 to rotate, the three sides of the narrow green belt can be trimmed. When trimming a hollow green belt with other green plants planted in the middle, the blades 12 on both sides can be adjusted to move to both sides. When the driving motor three 11 and the motor four 13 drive the blade one 12 and the blade two 14 to rotate, the middle blade one 12 and the two blades two 14 can trim the three sides of the green plants in the middle, and the blades 12 on both sides can trim the top of the hollow green belt, and the two sides of the hollow green belt can be trimmed by the adjusted middle blade one 12 and the two blades two 14. At the same time, the motor one 31 can drive the threaded rod 33 to rotate forward and reverse, and the threaded rod 33 and the cross plate 2 are transmitted. In this process, the cross plate 2 moves vertically under the limit of the limit frame 32, that is, moves up or down, to control the height position of the blade one 12 and the blade two 14 thereon.
