Dust-proof and noise-proof device for construction site

Abstract

The invention discloses a dust-proof and noise-proof device for a construction site, which includes a dust collection cover for collecting dust generated when materials are cut and polished on the construction site. The dust collection cover is movably connected with the equipment shell through a rotating shaft. The exhaust fan is used to extract the dust in the dust collection cover. The air inlet end of the exhaust fan is connected with the dust collection cover through the air pipe, and the air outlet end of the exhaust fan is connected with the dust storage device through the air pipe. In the present invention, By setting up the dust collection cover, air duct and exhaust fan, the exhaust fan can collect and absorb the dust under the dust collection cover during use, and then store it in the dust storage through the air duct, effectively preventing the dust from spreading environment, to prevent harm to the human body, the casing is equipped with three layers, which are cold-rolled sheet layer, rock wool layer and extruded sheet layer from the outside to the inside, which have a good noise absorption effect when the equipment is working, and prevent the equipment from generating noise. Noise can damage human hearing.

Description

technical field [0001] The invention relates to the technology in the field of construction equipment, in particular to a dust-proof and noise-proof device for a construction site. Background technique [0002] During the construction of the construction site, wooden boards are needed as the pouring mold for the building wall, or the wooden square is used to support the mold, so a cutting saw is needed, and some other auxiliary tools also need to be polished by a grinder, whether it is a cutting saw or a grinding machine. When the machine is in use, it will generate a lot of noise, and the dust floating out will fill the air, which is not environmentally friendly and will cause great harm to the staff. [0003] Therefore, the present invention provides a dust-proof and noise-proof device for construction sites. Contents of the invention [0004] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a dust-proo...

Problems solved by technology

[0004] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a dust-proof and noise-proof device for the construction site, so as to solve the problem that the construction site mentioned in the above-mentioned background requires wooden boards as a building block during construction. The pouring mold of the wall, or the use of wooden squares to support the mold, requires the use of a cutting saw, and some other auxiliary tools also need to be polished by a grinder. Whether it is a cutting saw or a grinder, a lot of noise will be generated when it is used , and the dust floating in the air is very unenvironmental, and it is also very harmful to the staff
