[0027] Reference Figure 1 , Figure 3 and Figure 4 The adjusting and fixing mechanism 11 includes a positioning groove 111 provided on the side of the frame 1 close to the mounting rod 4, and a positioning column 112 is fixedly connected to the side of the mounting rod 4 close to the positioning groove 111. The positioning column 112 at least partially extends into the positioning groove 111, and the positioning column 112 fits tightly with the positioning groove 111. When adjusting the relative angle between the mounting rod 4 and the frame 1, the positioning groove 111 and the positioning column 112 can prevent the mounting rod 4 from being separated from the frame 1.

[0028] Reference Figure 3-Figure 5 The adjusting and fixing mechanism 11 also includes two groups of slide grooves 113 opened on the side of the frame 1 close to the mounting rod 4, and a push rod 114 is slidably connected inside the slide groove 113. A first spring 115 is fixedly connected between the push rod 114 and the slide groove 113. The side of the push rod 114 close to the first spring 115 is inclined. A mounting groove 116 is opened on the side of the mounting rod 4 close to the slide groove 113. A limiting rod 117 is slidably connected in the mounting groove 116. A second spring 118 is fixedly connected between the limiting rod 117 and the mounting groove 116. A limiting groove 119 is opened on the frame 1, and the limiting groove 119 runs through the two groups of slide grooves 113. The limiting groove 119 passes through the two groups of slide grooves 113. A pressure plate 120 is slidably connected in the groove 119. Initially, under the action of the second spring 118, the limit rod 117 is located in one of the slide grooves 113, and the mounting rod 4 is limited to ensure the stable operation of the cutting disk 10. When the working state of the cutting disk 10 needs to be adjusted, the pressure plate 120 is pressed downward to make the push rod 114 push the limit rod 117 out, and the mounting rod 4 can be rotated. The pressure plate 120 is released, and when the mounting rod 4 is rotated to a certain angle, the limit rod 117 will move to the other slide groove 113 under the action of the second spring 118, and the mounting rod 4 will be fixed to ensure the stable operation of the cutting disk 10.

[0029] Reference Figure 1-Figure 2 The cutting disc 10 includes a mounting disc and a cutting knife, wherein the relative angle between the cutting knife and the mounting disc is adjustable, the cutting knife is arranged in an arc shape, and the connection method between the cutting knife and the mounting disc is a conventional method in the prior art, so it is not described in detail.

[0030] Reference Figure 1 , and also includes a diverter plate 12 fixedly connected to the bottom of the frame 1. The diverter plate 12 is conical and located on the center line between the two sets of cutting discs 10. The cut weeds are concentrated on both sides of the frame 1 under the action of the diverter plate 12. On the one hand, it can prevent the weeds from affecting the walking of the equipment, and on the other hand, it is convenient to clean the weeds.

[0031] Reference Figure 1 A crushing disc 13 and a driving device 14 are rotatably connected to the frame 1, and the driving device 14 is connected to the crushing disc 13. The specific structure of the crushing disc 13 can refer to the technical solutions in the prior art, and those skilled in the art can know it, so it will not be described here.

[0032] In the utility model, when weeds are cleaned, if fresh weeds are removed, the cutting disc 10 is in a horizontal state, and when the walking wheel 2 is moving, the motor 5 drives the driven wheel 8 to rotate through the driving wheel 6 and the belt 9, driving the two sets of cutting discs 10 to rotate in opposite directions, and then the weeds can be thrown to both sides of the frame 1 while the weeds are cleaned. At the same time, under the action of the diverter plate 12, the weeds remaining at the bottom of the frame 1 are reduced, and then the driving device 14 drives the crushing disc 13 to crush the roots of the weeds to reduce the regeneration of the weeds; if dead grass is removed, the pressing plate 120 is pressed downward so that the top rod 114 moves the limit rod 1 17 is pushed out, the mounting rod 4 can be rotated, and the pressure plate 120 is loosened. When the mounting rod 4 is rotated to a certain angle, the limit rod 117 will move to another slide groove 113 under the action of the second spring 118 to fix the mounting rod 4. At this time, the cutting disc 10 is in a vertical state, so that the frame 1 can crush the weeds during the walking process. Since it is aimed at weeds with a higher height, it has a better crushing effect. The crushed weeds are spread on the ground, and the diverter plate 12 can scrape the weeds flat. Finally, the weed fertilizer can be mixed into the soil through the crushing disc 13 to promote the growth of fruit trees.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
