Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] like Figures 1 to 5As shown, the present invention provides a dust suction fan assembly for a sanitation vehicle, comprising a dust suction shell 1; an inverted U-shaped dust inlet pipe 2 is arranged in the dust suction shell 1, and the U-shaped opening of the inverted U-shaped dust inlet pipe 2 is arranged on the bottom surface of the dust suction shell 1, and a cutting opening 3 is arranged on the bottom surface of the dust suction shell 1, and the cutting opening 3 is located in the U-shaped opening of the inverted U-shaped dust inlet pipe 2; a cutting assembly 4 is movably arranged in the cutting opening 3; a dust suction pipe 5 is connected to the inverted U-shaped dust inlet pipe 2, and one end of the dust suction pipe 5 away from the inverted U-shaped dust inlet pipe 2 passes through the outside of the dust suction shell 1; the cutting assembly 4 includes symmetrically arranged in both ends of the U-shaped opening of the inverted U-shaped dust inlet pipe 2 A pushing cylinder 41 is arranged on the wall, and a flip motor 42 is arranged on the piston rod of the pushing cylinder 41, and a flip plate 43 is arranged on the output shaft of the flip motor 42, and a cutting disc 44 and a blocking plate 45 which are adapted to the size and shape of the cutting opening 3 are respectively arranged on opposite sides of the flip plate 43; a slide groove 21 is arranged on the inner wall at both ends of the U-shaped opening of the inverted U-shaped dust inlet pipe 2, and a slide seat 22 is slidably arranged in the slide groove 21, and the flip motor 42 is respectively embedded in the slide seat 22 at the corresponding position, and the flip plate 43 is located between the two slide seats 22; the blocking plate 45 is connected to the flip plate 43 by a compression spring 451.

[0038] First, according to the needs of use, choose to use the cutting disk 44 or the blocking plate 45; when the cutting disk 44 is not needed, start the pushing cylinder 41 to drive the slide 22 (the slide 22 slides in the slide groove 21) and the flip motor 42 to move in the direction away from the cutting opening 3 (the cutting disk 44 and the blocking plate 45 can move synchronously); then start the flip motor 42 to drive the flip plate 43 to rotate, so that the blocking plate 45 rotates to a position close to the cutting opening 3; then start the pushing cylinder 41 to drive the slide 22 and the flip motor 42 to move in the direction close to the cutting opening 3 (the cutting disk 44 and the blocking plate 45 can move synchronously) until the blocking plate 45 is stuck in the cutting opening 3 to block the cutting opening 3 (at this time, the blocking plate 45 can squeeze the compression spring 451, which is beneficial to improve the sealing effect between the blocking plate 45 and the cutting opening 3); at this time, the dust and garbage on the road surface can be absorbed through the U-shaped opening of the inverted U-shaped dust inlet pipe 2.

[0039] When there are longer branches on the road that need to be cut off, the cutting disc 44 is required to be used, and the pushing cylinder 41 is started to drive the slide 22 and the flip motor 42 to move in the direction away from the cutting opening 3 (the cutting disc 44 and the blocking plate 45 can move synchronously); then the flip motor 42 is started to drive the flip plate 43 to rotate, so that the cutting disc 44 rotates to a position close to the cutting opening 3; then the pushing cylinder 41 is started to drive the slide 22 and the flip motor 42 to move in the direction close to the cutting opening 3 (the cutting disc 44 and the blocking plate 45 can move synchronously) until the cutting disc 44 is located in the cutting opening 3. As the dust collection housing 1 follows the movement of the sanitation vehicle, when the cutting opening 3 passes the position of the longer branches, the rotation of the cutting disc 44 can cut off the longer branches.
