A hand-held concrete wall roughening device with dust removal function

Abstract

The invention discloses a handheld concrete wall roughening device with a dedusting function. The handheld concrete wall roughening device is mainly used for the field of constructional engineering and used for roughening concrete walls or column surfaces. The handheld concrete wall roughening device is simple in structure, is provided with a dedusting device and is mainly composed of a polishing disk, a fan cover, a hollow rotating shaft, a bearing, a motor, an outer cover, a handle and a dust absorbing device. According to the working principle of the handheld concrete wall roughening device, a rotor of the motor rotates to drive the hollow rotating shaft, the fan cover and the polishing disk to rotate, a plurality of rhombic polishing heads on the polishing disk polish the concrete surface to be smooth and rough, at the time, a fan of the dust absorbing device rotates, the dust polished from the concrete surface enters the hollow rotating shaft through round holes which are distributed evenly, the dust enters a cavity of the handle after passing through the dust absorbing device, and after the cavity is full of the accumulated dust, a cover plate at the lower end of the handle is opened, and the dust is taken out.

Description

technical field [0001] The invention is mainly used for smoothing the surface of concrete walls or columns in the field of construction engineering. Background technique [0002] Applied for or authorized relevant concrete wall roughening device at present, its structure is all complicated and does not have dedusting device. Contents of the invention [0003] The present invention overcomes the above-mentioned defects. It has a simple structure and a dust removal device; it mainly consists of a grinding disc (1), a wind cover (2), a hollow shaft (3), a bearing (4), a motor (5), and an outer cover (6). , a handle (7), and a dust suction device (11); the grinding disc (1) has a plurality of uniformly distributed round holes (10) and a diamond-shaped grinding head (9), and the left end of the wind cover (2) is connected to the grinding disc (1 ) is fixed, the right end of the windshield (2) is fixed to the left end of the hollow shaft (3), the left and right ends of the holl...
