Variable-volume garbage can of sweeping car

Abstract

The invention provides a variable-volume garbage can of a sweeping car. The garbage can is divided into three areas including a clear water tank area, a normal-pressure sewage tank area and a negative-pressure sewage tank area, wherein sewage in the negative-pressure sewage tank area is pumped into the normal-pressure sewage tank area by a sewage pump, the interconversion of the clear water volume and the sewage volume between the clear water tank area and the normal-pressure sewage tank area can be realized by virtue of soft variable-volume walls, garbage and sewage in the normal-pressure sewage tank area and the negative-pressure sewage tank area can be simultaneously poured by discharge doors, and simultaneously, the normal-pressure sewage tank area and the negative-pressure sewage tank area are sealed. The volume interconversion between the clear water tank area and the sewage tank area can be realized by virtue of the soft variable-volume walls, so that the utilization rate of the volume of the garbage can is increased, and the uninterrupted working time of the sweeping car is greatly extended.

Description

Technical field

[0001] The invention relates to a special vehicle for road cleaning and sanitation, in particular to a dustbin with a variable capacity structure for a washing and sweeping vehicle. Background technique

[0002] At present, the dustbin of the sweeper is generally divided into two areas, one of which is the clean water tank area and the other is the sewage tank area. Normally, the volume of these two areas is fixed and unchanged. During the operation of washing and sweeping the pavement by the scrubber, the clean water in the clean water tank cleans the pavement and becomes sewage together with sludge and garbage, which are recovered through the suction cylinder. In the sewage tank, the clean water in the trash bin keeps decreasing, and the sewage keeps increasing. Since the volumes of the clean water tank area and the waste water tank area are fixed, the volumes between the areas cannot be converted to each other, which will inevitably cause a lot of waste of spa...
