The end of the second rotating rod is fixedly connected to the end of the toggle rod 2 431, the rod body of the second rotating rod is rotatably connected to one end of the fixed frame 3 432, and the other end of the fixed frame 3 432 is fixedly connected to the lower part of the moving member 31.

[0036] like Figure 7 , Figure 9 and Figure 10 As shown, the leaf removal assembly 5 includes a friction block 51, an elastic top piece 1 52, an elastic top piece 2 53 and a force-bearing rotating piece 54. The upper portion of the elastic top piece 1 52 is fixedly connected to the lower portion of the moving piece 31, the lower portion of the elastic top piece 1 52 is fixedly connected with the friction block 51, the upper portion of the elastic top piece 2 53 is fixedly connected to the lower portion of the moving piece 31, the lower portion of the elastic top piece 2 53 is fixedly connected with the friction block 51, and a force-bearing rotating piece 54 is arranged between the elastic top piece 1 52 and the elastic top piece 2 53.

[0037] The elastic top member 52 includes a first driving part, a sliding rod 521, a limiting handle 522, a spring 523 and a connecting rod 520. The front part of the first driving part is fixedly connected to the end of the sliding rod 521, the rod body of the sliding rod 521 is sleeved with a spring 523, the middle part of the sliding rod 521 is slidably connected to the hole opened by the limiting handle 522, the end of the limiting handle 522 is fixedly connected to the lower part of the moving member 31, the rear part of the first driving part is fixedly connected to one end of the connecting rod 520, and the other end of the connecting rod 520 is fixedly connected to the friction block 51. The elastic top member 2 53 includes a second driving part, a sliding rod 2 531, a limiting handle 2 532, a spring 2 533 and a connecting rod 2 530. The front part of the second driving part is fixedly connected to the end of the sliding rod 2 531, the rod body of the sliding rod 2 531 is sleeved with a spring 2 533, the middle part of the sliding rod 2 531 is slidably connected to the hole opened by the limiting handle 2 532, the end of the limiting handle 2 532 is fixedly connected to the lower part of the moving member 31, the rear part of the second driving part is fixedly connected to one end of the connecting rod 2 530, and the other end of the connecting rod 2 530 is fixedly connected to the friction block 51. The force-bearing rotating member 54 includes a push rod 541 and a fixing frame 4 542. The middle part of the force-bearing rotating member 54 passes through the rod body fixedly connected to the push rod 541, the end of the push rod 541 is rotatably connected to one end of the fixing frame 4 542, and the other end of the fixing frame 4 542 is fixedly connected to the lower part of the moving member 31.

[0038] When the moving member 31 drives the wheel 41 to move downward through the fixed frame 1 414, because the friction ring 411 contacts the rod body of the spiral lifting mechanism 3, the movement of the wheel 41 will generate friction, thereby causing the wheel 41 to rotate. At this time, the wheel 41 will drive the bevel gear column 1 412 and the bevel gear column 2 413 to rotate in the same direction. At this time, the bevel gear column 1 412 drives the toggle rod 1 421 to rotate counterclockwise through the power gear 1 42, and the bevel gear column 2 413 drives the toggle rod 2 431 to rotate clockwise through the power gear 2 43. At this time, the power gear 2 43 and The reciprocating rotation of the power gear 42 will drive the leaf removal assembly 5 to make a reciprocating movement. First, when the column at the end of the toggle rod 421 moves into the groove of the force-bearing rotating member 54, the force-bearing rotating member 54 will be pressed by the rotating toggle rod 421 to rotate a certain amplitude. At this time, the force-bearing rotating member 54 will drive the top rod 541 to rotate, so that the top rod 541 presses against the elastic top member 52, so that the elastic top member 52 moves up in a short time. As the toggle rod 421 continues to move, the toggle rod 421 will be out of the groove of the force-bearing rotating member 54. At this time, the toggle rod The rotation of rod 2 431 will be the same as that of toggle rod 1 421. Toggle rod 2 431 will resist the groove of force-bearing rotating member 54, so that force-bearing rotating member 54 will be reset along the original motion trajectory. At this time, top rod 541 will resist the elastic top member 2 53 to move up briefly. First, when the elastic top member 1 52 moves up, the elastic top member 1 52 will drive the friction block 51 to move through connecting rod 1 520. At this time, the sliding rod 1 521 connected to the elastic top member 1 52 will slide under the restriction of the limit handle 1 522, and the spring 1 523 will provide the elastic top member 1 52 after moving up. Reset power, after being pushed by the top rod 541, the elastic top piece 2 53 will have the same action as the elastic top piece 1 52, because the friction block 51 is provided with a protruding spike at the bottom, and the action of the friction block 51 will cause the leaves to pass through the elastic top piece 1 52 and the elastic top piece 2 53 to drive the action of the friction block 51, and pierce the leaves on the spiral lifting mechanism 3, and cooperate with the movement of the moving piece 31 to make the leaves firmly concentrated on the friction block 51, so as to prevent the leaves from falling everywhere after cleaning the spiral lifting mechanism 3 and hanging on the spiral lifting mechanism 3 again.

[0039] The present invention can make the friction block 51 move downward through the moving part 31, so that the branches hung on the spiral lifting mechanism 3 will be separated from the rod body of the spiral lifting mechanism 3 when the friction block 51 pushes the branches. In addition, the reciprocating motion of the friction block 51 can collect the leaves, so as to prevent the leaves that have separated from the rod body of the spiral lifting mechanism 3 from being hung on the spiral lifting mechanism 3 again due to floating.

[0040] like Figure 8As shown, the collecting assembly 6 includes: a fixed rod 61, a fixed frame 62, a rotating flap 63, and a limiting ring 64. The upper part of the fixing member 32 is fixedly connected to one end of the fixed rod 61, the other end of the fixed rod 61 is fixedly connected to the outer wall of the fixed frame 62, the inner wall of the fixed frame 62 is rotatably connected to the end of the rotating flap 63, and the upper part of the fixed frame 62 is fixedly connected to the end of the limiting ring 64. Among them, the fixed frame 62 includes a frame body, a positioning handle 621 and a spring three 622. The lower part of the fixed frame 62 is fixedly connected to one end of the positioning handle 621, the other end of the positioning handle 621 is fixedly connected to one end of the spring three 622, and the other end of the spring three 622 is fixedly connected to the plate surface at the lower part of the rotating flap 63.

[0041] When the friction block 51 moves with the collected leaves toward the position of the fixing member 32, the bottom of the friction block 51 will first contact the rotating flap 63. As the friction block 51 continues to move, the rotating flap 63 will be pressed and rotated. The rotation of the rotating flap 63 will cause the spring 3 622 to be squeezed. As the friction block 51 continues to move, all the leaves collected by the piercing member at the bottom of the friction block 51 enter the fixing frame 62. At this time, the rotating flap 63 is not squeezed by the friction block 51. It will be reset, and when the movable part 31 drives the friction block 51 to move upward, the part of the friction block 51 that collects the leaves will again press against the plate surface at the bottom of the rotating flap 63, and because a fixed limiting ring 64 is provided on the upper part of the rotating flap 63, the rotating flap 63 cannot rotate upward. Therefore, when the friction block 51 drives the leaves to move upward, the leaves stacked on the piercing part of the friction block 51 will be pressed by the rotating flap 63, and the upward movement of the friction block 51 will cause the leaves to be pulled away from the piercing part of the friction block 51.

[0042] The present invention drives the friction block 51 to move upward through the action of the collecting component 6 cooperating with the moving part 31, so that the leaves concentrated at the lower part of the friction block 51 can be cleaned in one go by the collecting component 6, thereby avoiding the friction block 51 not being cleaned in time the next time the leaves are cleaned, resulting in a poor cleaning effect.

[0043] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
