Embodiment

[0015] The air control device for the suction cup of the road sweeper in this embodiment is applied to a road sweeper with an air source on the chassis, and the road sweeper has a suction cup 1 located at the rear of the rear axle.

[0016] The road sweeper sucker air control device of the present embodiment, such as figure 1 As shown, it includes: a lifting mechanism, an anti-drop mechanism and a baffle flip mechanism; the lifting mechanism includes a lifting cylinder support 2 and a lifting cylinder 3; the lifting cylinder support 2 is fixed on the chassis frame of the road sweeper; the cylinder barrel of the lifting cylinder 3 is hinged On the lifting cylinder bracket 2, the piston rod of the lifting cylinder 3 is connected to the suction cup 1 of the road sweeper through a U-shaped buckle 4.

[0017] The anti-drop mechanism includes a connecting rod bracket 5, a connecting rod 8, a locking cylinder 6, a locking hook 7 and a locking pipe 9; One end of the connecting rod is...

Abstract

The invention relates to a pneumatic control device for a suction cup of a sweeping machine. The pneumatic control device comprises a lifting mechanism, an anti-falling mechanism and a baffle turnover mechanism. According to the pneumatic control device for the suction cup of the sweeping machine, mechanism movement of a suction cup body is completed through the three air cylinders, compared with a hydraulic system, cost is reduced, oil leakage pollution is avoided, the problem that the suction cup falls automatically due to air pressure reduction is solved through the anti-falling mechanism, and a baffle turnover device can guarantee that the suction cup can suck light garbage such as leaves and large garbage.

Description

technical field [0001] The invention relates to an air control device for a suction cup of a road sweeper, belonging to the technical field of special vehicles. Background technique [0002] The suction cup is the main part of the road sweeper. Its function is to collect the garbage collected by the sweeping brush so that the fan can suck the garbage into the garbage box. During the cleaning work, the suction cup falls to the ground and needs to be lifted when the work is finished. For garbage with large surface area and light weight such as fallen leaves, the rubber plate at the front of the suction cup will prevent the garbage from entering the interior of the suction cup, so it is necessary to adjust the opening of the suction port and turn up the rubber plate at the front to allow the garbage to enter smoothly. Most of the current road sweepers use hydraulic cylinders to lift the suction cup and flip the rubber plate. The advantages of using hydraulic cylinders are large...
