[0018] Embodiment 1

[0019] Such as Figure 1 , Figure 2 and Figure 3As shown, a leaf suction device for garden maintenance includes a movable base plate 1 and a leaf suction machine 3 and a leaf suction box 2 arranged on the top of the base plate 1, one end of the leaf suction machine 3 is connected to the leaf suction box 2 through a material guide pipe 5, and the other end of the leaf suction machine 3 is connected to a suction port through a connecting pipe 4. It also includes a material collection mechanism arranged below the base plate 1, the material collection mechanism includes a material collection cleaning arm 6 rotatably arranged on both sides of the suction port and a control mechanism 7 for controlling the material collection cleaning arm 6 to rotate open and close to achieve material collection, the material collection cleaning arm 6 can contact the road surface, and when the material collection cleaning arm 6 is retracted from the outside to the inside, the fallen leaves on both sides are collected to the suction port.

[0020] A lifting plate 8 is also provided below the bottom of the base plate 1, and the material collecting mechanism is installed on the lifting plate 8. Lifting mechanisms 9 for controlling the lifting and lowering of the lifting plate 8 are provided on both sides of the base plate 1. When the material collecting mechanism is not in use, the structure can make the material collecting cleaning arm 6 of the material collecting mechanism contact or separate with the road surface by lifting and lowering the lifting plate 8. It can be lifted when not in use, and lowered to contact with the road surface when in use.

[0021] Specifically, the lifting mechanism 9 includes four first telescopic cylinders 91 disposed on both sides of the bottom plate 1 and four guide rods 92 disposed at the four corners of the bottom of the bottom plate 1. The four first telescopic cylinders 91 are disposed downward, and the lower telescopic ends of the first telescopic cylinders 91 are fixedly connected to the lifting plate 8, and the guide rods 92 are fixed to the upper surface of the lifting plate 8, and the upper ends of the guide rods 92 are slidably connected to the guide holes on the bottom plate 1. The first telescopic cylinders 91 may be electric telescopic cylinders. As a result, the lifting plate 8 is lifted and lowered by the extension and retraction of the first telescopic cylinders 91, thereby controlling the lifting and lowering of the aggregate cleaning arm 6.

[0022] In one embodiment, the control mechanism 7 includes two connecting rods 72, two connecting pieces 71, a sliding seat 73 and a second telescopic cylinder 74. One end of the aggregate cleaning arm 6 is rotatably connected to the bottom of the lifting plate 8. The second telescopic cylinder 74 is horizontally fixed to the bottom of the lifting plate 8. The telescopic end of the second telescopic cylinder 74 is connected to the sliding seat 73. The sliding seat 73 is slidably connected to a guide rail 75 provided at the bottom of the lifting plate 8. The two connecting rods 72 are respectively hinged on both sides of the sliding seat 73. The two connecting pieces 71 are respectively fixed on the two aggregate cleaning arms 6 and close to one end of the connecting rod 72. The outer ends of the two connecting rods 72 are rotatably connected to the connecting piece 71 on the corresponding side. The second telescopic cylinder 74 can be an electric telescopic cylinder. When the second telescopic cylinder 74 is extended, it pushes the sliding seat 73 to slide forward along the guide rail 75, the connecting rod 72 rotates, and drives the aggregate cleaning arm 6 to rotate through the connecting piece 71, thereby controlling the opening or closing of the aggregate cleaning arm 6.

[0023] During the leaf suction process, the worker pushes the leaf suction device to move, and sucks the fallen leaves on the road surface through the suction port at the end of the leaf suction machine 3. The fallen leaves are automatically sucked into the leaf suction box 2 through the connecting pipe 4 and the material guiding pipe 5. At the same time, during the leaf suction process, in order to expand the suction range, the second telescopic cylinder 74 extends to push the sliding seat 73 to move forward, so that the connecting rod 72 pushes the aggregate cleaning arm 6 to open through the connecting plate 71. Then, the lifting plate 8 drives the aggregate cleaning arm 6 to move downward to contact the road surface. Then, the second telescopic cylinder 74 contracts to push the aggregate cleaning arm 6 to close. During the closing process, the aggregate cleaning arm 6 sweeps the fallen leaves on both outer sides of the device, and can concentrate the fallen leaves on both sides to the suction port, which is convenient for the suction port to suck, thereby expanding the suction range.
