Sweeper

Abstract

The invention provides a sweeper. The sweeper comprises a frame, sweeping equipment, an oil way system, a garbage can and a garbage lifting oil cylinder. The sweeping equipment and the garbage can arearranged on the frame; the oil way system comprises an oil tank, a master pump assembly, a shunting device, a sweeping control valve assembly and a lifting control valve. The master pump assembly isconnected between the oil tank and the input end of the shunting device; the first output end of the shunting device is connected with the sweeping control valve assembly, the sweeping control valve assembly is connected with sweeping equipment and controls the sweeping equipment to act, the second output end of the shunting device is connected with the lifting control valve, the lifting control valve is connected with the garbage lifting oil cylinder, and the garbage lifting oil cylinder drives the garbage can to ascend and descend. The sweeping control valve assembly is arranged close to thesweeping equipment, and the lifting control valve is arranged close to the garbage lifting oil cylinder. The lifting control valve and the garbage lifting oil cylinder are arranged close to each other, so that an output pipeline can be connected with the garbage lifting oil cylinder through a short pipeline, wiring of an oil path is shortened, and the stability is improved.

Description

technical field [0001] The invention relates to the field of new energy sanitation equipment, in particular to a sweeping machine. Background technique [0002] At present, common vacuum suction type floor sweepers on the market generally have wheels for driving along the ground, at least one rotatably driven sweeping brush for cleaning the ground, and a vacuum dustbin. Surfaces such as streets, sidewalks or parking lots can be swept with the help of this floor sweeper. At least one sweeping brush of the floor sweeping machine acts on the ground to be cleaned and guides the cleaning material to the suction nozzle assembly, and the cleaning material is sucked by the suction nozzle assembly and transported into the vacuum garbage bin through a pipeline connected thereto. For this purpose, the vacuum waste container is loaded with negative pressure by the suction device, so that a suction flow is formed from the suction nozzle assembly to the vacuum waste container and from th...

Problems solved by technology

[0003] In order for the sweeper to cope with various complex road conditions and different modes of cleaning, the existing sweeper is equipped with sweeping brushes and suction cups that can move in multiple directions, as well as a reversible dumping bin. Due to the swing arm, sweeping brush, suction cup, oil cylinder The control oil circuit of many devices is relatively complicated. For this reason, the public number CN110725255A is called the sweeper to adjust and integrate the control structure of the oil circuit, and concentrate the control parts in the front frame, so as to facilitate management, wiring and control. However, since the rear frame is also equipped with a trash can and its cover that needs to be driven by the oil cylinder, it is necessary to carry out the layout of the oil circuit. However, this will also cause a certain amount of complicated wiring and affect the stability.
