[0011] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments;

[0012] Figure 1 is a schematic diagram of the present invention;

[0013] Figure 2 This is a schematic diagram of the vibration reduction principle of the present invention. DETAILED DESCRIPTION

[0014] like Figure 1 or Figure 2 As shown, the suction nozzle device with a vibration reduction function of the present invention is connected to a sanitation vehicle for sucking up garbage on the road surface, and includes a suction cup 1. The top of the suction cup 1 is connected to a suction cylinder 3 on the frame of the sanitation vehicle through a hose 2; the present invention also includes two connecting rods 4, which are respectively arranged on both sides of the suction cup 1, and hangers 5 are respectively fixed to the corresponding two connecting rods 4 on the outer side surface of the chassis beam of the sanitation vehicle. The head ends of the two connecting rods 4 are respectively rotatably connected to the corresponding hangers 5 through pins, and the ends of the connecting rods 4 are connected to rollers 6. When the suction cup 1 sucks up garbage on the ground, the rollers 6 are rollingly supported on the ground; the middle parts of the two connecting rods 4 are respectively rotatably connected to support rods 7, and the bottoms of the support rods 7 are fixedly connected to the top of the suction cup 1.

[0015] The top of the suction cup 1 is connected to a lifting cylinder 8 for lifting it, the cylinder body of the lifting cylinder 8 is hinged to the inner side of the chassis beam of the sanitation vehicle, and the push rod head of the lifting cylinder 8 is hinged to the top of the suction cup 1. When the suction cup 1 is not in operation, the suction cup 1 can be lifted by the lifting cylinder 8 to prevent the suction cup 1 from being damaged.

[0016] A limiting frame 9 is fixed on the inner side of the chassis beam of the sanitation vehicle, and a limiting buffer block 91 is fixed at the bottom of the limiting frame 9. The limiting buffer block 91 is used to limit the height position of the suction cup 1 after it is raised.

[0017] A screw rod 10 arranged in the vertical direction is threadedly connected to one side of the limit frame 9, a spring 11 is connected to the bottom of the screw rod 10, a chain 12 is connected to the lower end of the spring 11, and the lower end of the chain 12 is connected to the front end of the suction cup 1. When the suction cup 1 is in operation, the chain 12 can assist in lifting the front end of the suction cup 1 to prevent the front end of the suction cup 1 from sagging and affecting the efficiency of sucking and picking up garbage.

[0018] A long screw 10 is provided at the top of the end of the connecting rod 4, and a long slot hole is provided at the top of the roller 6. The position of the roller 6 can be adjusted by connecting the long screw 10 and the long slot hole. Before the suction cup 1 is operated, the ground clearance of the suction cup 1 can be adjusted by adjusting the long screw 10 and the roller 6.

[0019] like Figure 2 As shown, according to the vibration reduction principle of the present invention, when the suction cup 1 is working, the roller 6 jumps upward by a distance CC', and the suction cup 1 jumps upward by a distance BB' (smaller than CC') through the support rod 7, thereby achieving a vibration reduction effect.

[0020] The implementation of the present invention is described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes. The above-mentioned specific implementation modes are illustrative rather than limiting the present invention. Those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
