Cleaning and dust absorption device

Abstract

The embodiment of the invention discloses a cleaning and dust absorption device, which comprises a right-handed rotation roll brush, first rolling bearing units, a left-handed rotation roll brush, an engine base, a caster mounting seat, a caster, a dust absorption part, two drive parts, transmission parts, bracket spacers, a bracket and a steering part, wherein the right-handed rotation roll brush is provided with bristles linearly arranged in a right-hand screw manner; the left-handed rotation roll brush is provided with bristles linearly arranged in a left-hand screw manner; the right-handed rotation roll brush and the left-handed rotation roll brush are directly mounted on the first rolling bearing units through a roll brush shaft; the dust absorption opening of the dust collection part is formed in the bottom of the engine base; one end of the bracket is fixed with the engine base; the other end of the bracket is fixed on the steering part; the bracket spacers are arranged on the upper surface and the lower surface of the bracket. According to the device, a double-roll brush structure with bristles in different rotation directions, different cleaning manners can be realized through controlling rotation directions of the roll brushes, and meanwhile the steering part is arranged, so that the problems of single cleaning operation mode, incapability of flexible and free cleaning operation and poor cleaning efficiency are solved.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment, in particular to a cleaning and dust suction device. Background technique [0002] The cleaning and dust suction devices in the prior art generally all adopt a rolling brush body, and the cleaning area is relatively small. The Chinese patent with the publication number CN 201665841U discloses a walk-behind sweeper, which includes a frame, handrails, and ground wheels. A horizontal rotating shaft is arranged at the front of the frame. The horizontal rolling brushes are assembled on the rotating shaft, and the lateral rolling brushes are assembled on both sides of the front of the frame. The rotating shaft of the lateral rolling brush is connected to the horizontal device rotating shaft through the transmission device. A conveyor belt is installed in front of the collection port. The front end of the conveyor belt is located behind and below the horizontal roller brush, and the rear of ...
