Sewage recycling mechanism for washing and sweeping vehicle

Abstract

The invention provides a sewage recycling mechanism for a washing and sweeping vehicle. The sewage recycling mechanism comprises a water scraping rake, a bottom plate, and a dustbin; the dustbin is arranged above the bottom plate, a water scraping rake bracket is arranged on the bottom plate, the water scraping rake is arranged on the water scraping rake bracket, the dustbin is divided into two layers, the upper layer is a sealed sewage tank, the lower layer is a dustbin body for containing garbage, the lower end of the dustbin body is provided with an upper sewage suction pipe in a welded mode, one end of the upper sewage suction pipe extends into the sewage tank, a fan is arranged at the top of the dustbin body, air of the sewage tank in the dustbin body is pumped by the fan to generatenegative pressure in the sewage tank, the bottom plate is provided with a lower sewage suction pipe bracket, the lower sewage suction pipe bracket is provided with a lower sewage suction pipe, the upper sewage suction pipe and the lower sewage suction pipe are tightly attached to each other, and a pressure spring is arranged between the upper sewage suction pipe and the lower sewage suction pipe.The outlet for making the sewage tank communicate with the outside is located at the water scraping rake, so that sewage on the ground is recovered, the sewage collection work is automatically completed, the sewage is prevented from entering the fan through a check valve, and the service life of equipment is prolonged.

Description

Technical field [0001] The invention relates to the field of road cleaning, in particular to a sewage recovery mechanism for washing and sweeping vehicles. Background technique [0002] At present, when cleaning the road, because there will be sewage on the road, whether it is troublesome to clean up, it is necessary to wash and sweep the car to recover the sewage when cleaning. At present, the sewage is recycled, generally by wiping with a mop. Adsorption, but the above method cannot carry out large-scale sewage cleaning, and there will still be residual sewage after cleaning, resulting in unclean sewage removal and affecting the cleanliness of the road. Therefore, it is particularly important to solve the problem that the current washing and sweeping vehicle is difficult to collect and clean sewage. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a sewage recovery mechanism for washing and sweepi...

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a sewage recovery mechanism for cleaning and sweeping vehicles, which uses a fan to pump air into the sewage tank in the garbage box to make it generate negative pressure, and the sewage tank is fully sealed structure, when the maintenance port and the water discharge port are closed, only the upper sewage suction pipe is connected to the outside world, and the upper sewage suction pipe is closely attached to the lower sewage suction pipe and connected by the rubber tube, so that the sewage tank is connected to the outside world The outlet is at the wiper rake, so that the sewage on the ground will be recycled, and the sewage collection work will be automatically completed, which solves the problem that it is difficult to collect and clean sewage in the current sweeper
