Concrete mixer dust cover applied in constructional engineering field

Abstract

The invention belongs to the field of dust covers, and particularly relates to a concrete mixer dust cover applied in the constructional engineering field. The concrete mixer dust cover comprises a cover case, a cover, a second revolving shaft, a stripped swing board, a heavy block, a second arc-shaped rack, a hinging plate, vortex springs, a belt and a driving gear and the like, wherein the dustcover can be opened automatically when materials need to be charged or discharged through feeding and discharging holes in a stirring barrel; the feeding and discharging holes in the stirring barrel are shielded by the dust cover in a process of stirring the concrete raw material in the stirring barrel, so that a large amount of raw material dust generated by rolling of the concrete raw material in the stirring barrel is prevented from leaking from the feeding and discharging holes and being diffused to surrounding atmosphere, the pollution of atmospheric air around a concrete mixer caused bythe leaking raw material dust is avoided, and the environment is protected at a certain degree. The concrete mixer dust cover has a simple structure, and a better using effect.

Description

technical field [0001] The invention belongs to the technical field of dust covers, in particular to a concrete mixer dust cover applied in the field of construction engineering. Background technique [0002] At present, there are many kinds of traditional concrete mixers on the market. Among them, the working principle of a concrete mixer is: the mixing mechanism is used to mix the concrete raw materials. The mixing drum is fixed and does not rotate during the mixing process of the concrete raw materials. The inlet and outlet of the drum rotate and tilt upward, and the inlet and outlet of the mixing drum need to be rotated and tilted downward when the mixing drum is unloading. For this kind of concrete mixer in which the mixing drum is fixed and does not rotate during the mixing process of concrete raw materials, in the early stage of the mixing process of concrete raw materials, because the concrete raw materials are not completely mixed into a viscous shape, the concrete ...

AI Technical Summary

Problems solved by technology

For this kind of concrete mixer in which the mixing drum is fixed and does not rotate during the mixing process of concrete raw materials, in the early stage of the mixing process of concrete raw materials, because the concrete raw materials are not completely mixed into a viscous shape, the concrete raw materials are not fully mixed into a viscous state in the early stage of the mixing process, and the concrete raw materials are being stirred. The tumbling in the barrel will cause a lot of raw material dust, and the raw material dust will emerge from the inlet and outlet of the mixing barrel and diffuse into the surrounding atmosphere, which will cause a certain amount of dust pollution to the atmosphere around the concrete mixer, and even damage the concrete mixer.
