A kind of dustproof cover used in construction engineering mixer

Abstract

The invention belongs to the technical field of dust covers, and in particular relates to a dust cover used in a construction engineering mixer. Incomplete bevel gears, lugs, cams, etc., among which the dust cover of the present invention can be automatically opened according to the inlet and outlet on the mixing drum when it needs to be loaded or discharged, and the concrete raw materials in the mixing drum are mixed. During the process, the inlet and outlet of the mixing drum are covered by a dust cover, so that the tumbling of concrete raw materials in the mixing drum will cause a large amount of raw material dust to not emerge from the inlet and outlet of the mixing drum and spread into the surrounding atmosphere, thus preventing It prevents the emission of raw material dust from causing air pollution around the concrete mixer and plays a certain environmental role. The invention has simple structure and good use effect.

Description

technical field [0001] The invention belongs to the technical field of dust-proof covers, and in particular relates to a dust-proof cover for construction engineering mixers. 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 raw ...

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. Breathing environment for workers working in the surrounding area
