A second bevel gear 65 is fixedly sleeved on the outer side wall of the rotating rod 66. The second bevel gear 65 meshes with the first bevel gear 64. A vertical plate 67 is installed on the outer side wall of the rotating rod 66 away from the second bevel gear 65. A cutting component is installed on the vertical plate 67. The cutting component includes a protective shell 68 installed on the lower end surface of the vertical plate 67. A third motor 69 is installed inside the protective shell 68. The power output shaft of the third motor 69 penetrates through the protective shell 68 and is connected with a second driving rod 691. A plurality of cutting blades 692 are annularly arranged at the bottom of the third motor 69. In the specific use process, start the third motor 69. The power output end of the third motor 69 drives the second driving rod 691 to rotate, and finally drives the cutting blades 692 to rotate. Start the first motor 52. The power output end of the first motor 52 drives the bidirectional lead screw 53 to rotate. When the bidirectional lead screw 53 rotates, the second slider 54 can be driven to move cyclically, increasing the cutting area. When encountering uphill and downhill, start the second motor 6. The power output end of the second motor 6 drives the first driving rod 63 to rotate, thereby driving the first bevel gear 64 to rotate. Through meshing, the second bevel gear 65 is driven to rotate, and finally the rotating rod 66 is driven to rotate, so that the cutting blades 692 are adjusted to a suitable angle.
[0019] As an implementation mode in this embodiment, as shown in Figure 2 and Figure 3As shown in the figure, the displacement mechanism includes a horizontal adjustment component. The horizontal adjustment component includes a support frame 5. A fixed plate 51 is installed on the side wall of the support frame 5. A first motor 52 is installed on the upper end surface of the fixed plate 51. The power output shaft of the first motor 52 passes through the support frame 5 and is connected to a bidirectional lead screw 53. And the end of the bidirectional lead screw 53 away from the first motor 52 is rotatably connected to the side wall of the connecting frame 4. A second slider 54 is threadedly sleeved on the bidirectional lead screw 53. The displacement mechanism further includes a height adjustment component. The height adjustment component includes a stepping motor 41 fixed on the top of the connecting frame 4. The power output shaft of the stepping motor 41 passes through the connecting frame 4 and is connected to a threaded rod 45. And the end of the threaded rod 45 away from the stepping motor 41 is rotatably connected to the bottom of the connecting frame 4. A first slider 42 is threadedly sleeved on the threaded rod 45.

One end of each of the two windshield guards 44 away from the first slider 42 is fixedly connected to the connecting frame 4. In the specific use process, first start the stepping motor 41. The power output end of the stepping motor 41 drives the threaded rod 45 to rotate. When the threaded rod 45 rotates, it drives the first slider 42 to move up and down. When the first slider 42 moves up and down, it drives the moving plates 43 to move up and down, so that the cutting blade 692 is adjusted to a suitable height. Through the provided windshield guards 44, the inside of the connecting frame 4 can be protected to prevent the removed weeds from entering the inside of the connecting frame 4 and affecting the operation of the equipment. After the height adjustment is completed, start the third motor 69. The power output end of the third motor 69 drives the second drive rod 691 to rotate, and finally drives the cutting blade 692 to rotate. Start the first motor 52. The power output end of the first motor 52 drives the bidirectional lead screw 53 to rotate. When the bidirectional lead screw 53 rotates, it can drive the second slider 54 to move cyclically in translation, increasing the cutting area.

A plurality of universal wheels 3 are fixedly installed at the bottom of the vehicle frame 1. In the specific use process, the vehicle frame 1 can be pushed through the provided push handle, and the direction can be adjusted through the provided universal wheels 3 to cut weeds in different directions.
[0021] Working principle: First, start the stepper motor 41. The power output end of the stepper motor 41 drives the threaded rod 45 to rotate. When the threaded rod 45 rotates, it drives the first slider 42 to move up and down. When the first slider 42 moves up and down, it drives the moving plate 43 to move up and down, so as to adjust the cutting blade 692 to an appropriate height. Through the provided bellows protective cover 44, the inside of the connecting frame 4 can be protected to prevent the removed weeds from entering the inside of the connecting frame 4 and affecting the operation of the equipment. After the height adjustment is completed, start the third motor 69. The power output end of the third motor 69 drives the second driving rod 691 to rotate, and finally drives the cutting blade 692 to rotate. Start the first motor 52. The power output end of the first motor 52 drives the bidirectional lead screw 53 to rotate. When the bidirectional lead screw 53 rotates, it can drive the second slider 54 to move cyclically in translation to increase the cutting area. When encountering an uphill or downhill, start the second motor 6. The power output end of the second motor 6 drives the first driving rod 63 to rotate, thereby driving the first bevel gear 64 to rotate. Through meshing, it drives the second bevel gear 65 to rotate, and finally drives the rotating rod 66 to rotate, so as to adjust the cutting blade 692 to an appropriate angle.
