Liftable sucker mechanism of dust collection vehicle

Abstract

The invention relates to a structural part of a sanitation truck, in particular to a liftable sucker mechanism of a dust collection vehicle. The liftable sucker mechanism of the dust collection vehicle comprises ascending / descending drive mechanisms, a sucker body and an auxiliary walking mechanism; the ascending / descending drive mechanisms are mounted on a chassis beam, the drive ends of the ascending / descending drive mechanisms are arranged downwards and connected with the sucker body through connection pieces, the auxiliary walking mechanism is fixed to the chassis beam and located on the front side of the sucker body in the walking direction, and the sucker body is connected with the auxiliary walking mechanism. The liftable sucker mechanism of the dust collection vehicle has the advantages that the mechanism is simple in structure and convenient to operate and use, and the sucker device is hung flexibly, so that when the sucker meets a highly protruding obstacle, the collision force can be effectively buffered, collision force is dispersed to a large degree, the situation that the sucker is collided and damaged is avoided, good traction force is achieved, and stability of the sucker in the dust collection process is maintained.

Description

technical field [0001] The invention relates to a structural accessory of a sanitation vehicle, in particular to a liftable sucker mechanism of a dust collection vehicle. Background technique [0002] The vacuum truck has the state of suction and sweeping operation and normal driving state. In the state of suction and sweeping operation, the vehicle is running at a slow speed ≤ 20 km / h, the suction cup is close to the ground, and the distance from the ground is ≤ 10mm, and the suction operation is carried out; in the normal driving state, the vehicle is driving at medium and high speed, and the suction cup is ≥ 250mm from the ground. [0003] The suction cups of conventional washing and sweeping vehicles are mostly fixed and rigidly installed on the front or rear side of the car body. It usually requires a complicated installation structure, and its lifting mechanism structure is relatively complicated, and it is more troublesome to drive up and down. If the suction cup is r...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a liftable suction cup mechanism of a dust collection vehicle, which effectively solves the troublesome installation of the suction cup of a conventional sweeping vehicle, and the lifting The structure of the mechanism is relatively complicated, and the operation is more cumbersome when driving. The suction cup of the traditional vacuum cleaner is relatively easy to be damaged when it encounters an obstacle, making the vehicle unable to continue to use, and the replacement of the suction cup requires additional use costs, and the suction cup of the traditional vehicle The structure is mostly fastened on the lifting device, which is inconvenient to disassemble and maintain, and wastes a lot of manpower and material resources
