The lower ends of each connecting rotating plate 64 are equipped with casters 65, and the rear ends of each caster 65 are equipped with self-locking components to lock the rotation of the casters 65. Cylinders 63 are located inside the connecting rotating plates 64 and between the two rotating shells 61. Rotating plates 66 are rotatably connected to the outer arc surfaces of the cylinders 63. The upper ends of each rotating plate 66 are rotatably connected to adjusting frame 67 via rotating shaft two. The frame 67 is laterally slidably connected to the lower surface of the frame 1. The self-propelled mechanism 6 also includes an adjusting motor 68 and a screw 69. The screw 69 is rotatably connected between the left and right inner walls of the slide groove on the lower surface of the frame 1. The screw 69 is threadedly connected to the screw hole on the surface of the adjusting frame 67. Corrugated tubes are respectively provided between the adjusting frame 67 and the left and right inner walls of the slide groove. The corrugated tubes are movably sleeved on the outer arc surface of the screw 69. During the movement of the adjusting frame 67, the corrugated tubes expand and contract, always providing protection for the screw 69. The adjusting motor 68 is set on the upper surface of the frame 1. The output shaft of the adjusting motor 68 is fixedly connected to the left end of the screw 69. The input end of the adjusting motor 68 is electrically connected to the output end of the microcontroller 3, providing power for the movement of the adjusting frame 67. Each end of the shaft of the self-propelled wheel 62 is equipped with a... Inside the rotating housing 61, bevel gear 9 and drive column 10 are rotatably connected. Both ends of drive column 10 have bevel gear 11. The right-side bevel gear 11 meshes with the adjacent bevel gear 9. Drive column 12 is rotatably connected to the rotating hole at the upper end of the rotating housing 61. Both ends of drive column 12 have bevel gear 13. The bevel gear 13 furthest from the center of the frame 1 meshes with the adjacent bevel gear 11. A drive motor 15 is located at the left end of the frame 1. A bevel gear 14 is located at the lower end of the output shaft of the drive motor 15. The bevel gear 13 closest to the center of the frame 1 meshes with the bevel gear 14. The input end of the drive motor 15 is electrically connected to the output end of the microcontroller 3, providing power for the rotation of the self-propelled wheel 62. The upper surface of the adjustment frame 67 is provided with guide holes 7. Guide posts are provided between the left and right inner walls of the slide groove on the lower surface of the frame 1. The guide posts are laterally slidably connected to the guide holes 7. The connecting rotating plate 64 includes a rotating plate 641 and a mounting plate 642. The mounting plate 642 is located on the lower surface of the frame 1. The front and rear sides of the mounting plate 642 are rotatably connected to two rotating plates 641 through a rotating shaft. The upper ends of the rotating plates 641 are rotatably connected to the rotating frame 2 on the right end of the lower surface of the frame 1. The cylinder 63 on the right side is set between two support plates on the upper surface of the mounting plate 642. The universal wheels 65 are respectively set on the lower surface of the mounting plate 642. During the movement, when walking on a slope, the electronic level inside the microcontroller 3 detects that the frame 1 is tilted.The tilt angle data is sent to the microcontroller 3, which controls the adjustment motor 68 to start. The output shaft of the adjustment motor 68 drives the screw 69 to rotate. Through the threaded connection between the screw 69 and the adjustment frame 67, and under the guidance and support of the guide column in the slide groove of the frame 1, the adjustment frame 67 moves left and right. When in an uphill state, the adjustment frame 67 moves to the right, shortening the distance between the adjustment frame 67 and the rotating frame 2 at the right end of the lower surface of the frame 1, and increasing the distance between the adjustment frame 67 and the rotating frame 1 at the left end of the lower surface of the frame 1. Under the rotational connection of the rotating plate 66, the self-propelled wheel 62 is pushed to rotate counterclockwise around the rotation axis at the upper end of the rotating shell 61, so that the distance between the self-propelled wheel 62 and the lower surface of the frame 1 is... The distance between the mounting plate 642 and the lower surface of the frame 1 is increased by rotating the mounting plate 642 counterclockwise around its upper axis. The front and rear sides of the mounting plate 642 rotate relative to the two rotating plates 641, maintaining the mounting plate 642 in a horizontal position. This increases the distance between the caster wheel 65 and the lower surface of the frame 1, causing the rear end of the frame 1 to tilt upwards. Similarly, when going downhill, the adjusting frame 67 moves to the left, tilting the front end of the frame 1 upwards, keeping the frame 1 horizontal while traveling on slopes. The weight of the equipment on the surface of the frame 1 applies a vertical force to the frame 1, increasing the grip of the self-propelled wheel 62 and the caster wheel 65, and reducing the probability of the entire device slipping while traveling on slopes.

[0022] The working principle of the self-propelled garden leaf collection and shredding mechanism for slopes provided by this utility model is as follows: When cleaning garden leaves, the microcontroller 3 starts the centrifugal fan 16. The negative pressure generated by the centrifugal fan 16 draws the fallen leaves from the ground into the suction pipe 4. The leaves move upward along the inside of the suction pipe 4. During this movement, the shredding motor on the surface of the suction pipe 4 is started. The output shaft of the shredding motor drives the shredding roller 5 to rotate. Through the relative rotation of the two shredding rollers 5, the fallen leaves are shredded. After shredding, the fallen leaves enter the leaf collection box 2 with the airflow. Under the filtration of the filter screen inside the air outlet pipe of the leaf collection box 2, the shredded leaves remain in the leaf collection box 2. Inside, fallen leaves are crushed and collected. During operation, the drive motor 15 is started, and the output shaft of the drive motor 15 drives the bevel gear 4 14 to rotate. The bevel gear 4 14 meshes with the bevel gear 3 13, the bevel gear 3 13 meshes with the bevel gear 2 11, and the bevel gear 2 11 meshes with the bevel gear 1 9, driving the self-propelled wheel 62 to rotate, providing power for the movement of the entire device. During movement, the direction of travel is adjusted by pushing the universal wheel 65 to rotate horizontally. When traveling on a slope, the electronic level inside the microcontroller 3 detects that the frame 1 is tilted and records the tilt angle data. The signal is sent to microcontroller 3, which controls the start of the regulating motor 68. The output shaft of the regulating motor 68 drives the screw 69 to rotate. Through the threaded connection between the screw 69 and the regulating frame 67, and under the guidance and support of the guide column in the slide groove of the frame 1, the regulating frame 67 moves left and right. When in an uphill state, the regulating frame 67 moves to the right, shortening the distance between the regulating frame 67 and the rotating frame 2 at the right end of the lower surface of the frame 1, and increasing the distance between the regulating frame 67 and the rotating frame 1 at the left end of the lower surface of the frame 1. Under the rotational connection of the rotating plate 66, the self-propelled wheel 62 is pushed to rotate counterclockwise around the rotation axis at the upper end of the rotating shell 61, thus reducing the distance between the self-propelled wheel 62 and the lower surface of the frame 1. The rotating plate 641 rotates counterclockwise around its upper rotation axis. The front and rear sides of the mounting plate 642 are affected by the relative rotation of the two rotating plates 641, keeping the mounting plate 642 in a horizontal state. This increases the distance between the caster wheel 65 and the lower surface of the frame 1, causing the rear end of the frame 1 to tilt up. Similarly, when in a downhill state, the adjusting frame 67 moves to the left, tilting the front end of the frame 1 up. This keeps the frame 1 in a horizontal state when walking on a slope. The weight of the equipment on the surface of the frame 1 is used to apply a vertical force to the frame 1, increasing the grip of the self-propelled wheel 62 and the caster wheel 65, and reducing the probability of the entire device slipping during the process of walking on a slope.

[0023] It is worth noting that the microcontroller 3 disclosed in the above embodiments can be a PIC16F1823-I / P model microcontroller. The regulating motor 68, drive motor 15 and centrifugal fan 16 can be freely configured according to the actual application scenario. The regulating motor 68 and drive motor 15 can both be 3M57-42A model stepper motors. The centrifugal fan 16 can be a C4-73 model dust removal centrifugal induced draft fan. The level inside the microcontroller 3 can be a CS10-WL9 model electronic level. The microcontroller 3 controls the operation of the regulating motor 68, drive motor 15 and centrifugal fan 16 using methods commonly used in the prior art.
