Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figure 1-5 As shown, a weeding machine with adjustable weeding range and weeding degree proposed by the present invention comprises a mounting plate 1, a multifunctional weeding assembly 2 is provided on one side of the mounting plate 1, a protective assembly 3 is provided on the outer side of the multifunctional weeding assembly 2, a recovery assembly 4 is provided on the other side of the mounting plate 1, rotating mobile auxiliary wheels 5 are provided on both sides of the recovery assembly 4, and a handrail 6 is also provided on the recovery assembly 4, the multifunctional weeding assembly 2 comprises a height adjustment assembly 7, a rotating motor 8 and a cutting knife 9, the height adjustment assembly 7 is fixedly arranged on the mounting plate 1, the rotating motor 8 is fixed on the height adjustment assembly 7 through a connecting frame, the cutting knife 9 is arranged on the output shaft of the rotating motor 8 through a range adjustment mounting structure 10, the height adjustment assembly 7 can change the trimming height and thus change the trimming degree when it is operated, and the trimming range can be adjusted by setting the range adjustment mounting structure 10 in cooperation with the cutting knife 9 on the one hand, and the cutting knife 9 can be replaced on the other hand to increase the service life of the weeding machine.

[0022] In order to facilitate the adjustment of the trimming range, the range adjustment mounting structure 10 includes a connecting shaft fixed on the output shaft of the rotating motor 8, a mounting seat threadedly connected to the blade mounting seat 11 and a fastening screw 13 threadedly connected to the blade mounting seat 11. A mounting hole 12 for mounting the cutting knife 9 is provided at the bottom of the blade mounting seat 11. The fastening screw 13 is against the cutting knife 9. The blade mounting seat 11 is removed from the connecting shaft and the fastening screw 13 is rotated to loosen the cutting knife 9. When the fastening screw 13 is located in the middle of the cutting knife 9, the trimming range is the smallest. The cutting knife 9 can be adjusted to the sides when it deviates. After adjustment, tighten the fastening screw 13 to fix the position of the cutting knife 9, install the blade mounting seat 11 on the connecting shaft, and the rotating motor 8 drives the cutting knife 9 to rotate to achieve trimming.

[0023] In order to adjust the trimming height, the height adjustment assembly 7 includes a screw mounting frame 14, a transmission motor 15, a screw 16 and a slider with a nut 17. The screw mounting frame 14 is fixed on the mounting plate 1, and the transmission motor 15 is fixed on one end of the screw mounting frame 14. One end of the screw 16 is fixed on the output shaft of the transmission motor 15 and the other end is rotatably arranged on the screw mounting frame 14. The slider with a nut 17 is threadedly connected to the screw 16 and is slidably connected to the screw mounting frame 14. The operation of the transmission motor 15 can drive the cutting knife 9 to approach the root or top of the grass, thereby adjusting the trimming height and degree.

[0024] In order to reduce damage to the height adjustment component 7 during weeding and reduce the amount of grass entering the height adjustment component 7, the protection component 3 includes a guard plate 18. The guard plates 18 are provided in two groups. The two groups of guard plates 18 are symmetrically arranged. The two groups of protective brushes 19 are provided on the opposite sides of the two groups of protective brushes 19. The two groups of protective brushes 19 block the nut slider 17. When the height adjustment component 7 is in operation, the connecting frame connected to the rotating motor 8 can move between the two groups of protective brushes 19, thereby not affecting the height adjustment.

[0025] In order to recycle the trimmed grass and facilitate resource utilization, the recycling component 4 includes a recycling box 20 and an air pump 21. The bottom of the recycling box 20 is hinged on the mounting plate 1, and the air pump 21 is arranged on the top of the recycling box 20. Protrusions 23 are vertically welded on the mounting plates 1 on both sides of the recycling box 20. Through holes are respectively provided at the corresponding positions of the protrusions 23 and the recycling box 20, and a detachable limiting rod 24 is provided on the through hole. Feed ports 22 are respectively opened on both sides of the mounting plate 1, and a protective net is provided at the position where the recycling box 20 is connected to the air pump 21. When the air pump 21 is running, the weeds cut off by the airflow enter the recycling box 20 through the feed port 22. When centralized processing is required, the limiting rod 24 is removed from the protrusion 23 and the recycling box 20 to recycle the grass in the recycling box 20.

[0026] During use, the user pushes the handrail 6 to move to a designated position to weed.
