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

specific Embodiment approach

[0067] Specific embodiments: the dust cover in the present invention is mainly suitable for the concrete mixer whose mixing drum is fixed and does not rotate during the mixing process of concrete raw materials, and when the mixing drum of this type of concrete mixer is feeding and discharging, the rotating mechanism makes the mixing When the material inlet and outlet 45 of the drum is facing upwards, the concrete raw materials are received, and when the inlet and outlet 45 of the mixing drum is facing downwards, the stirred concrete is discharged through the rotating mechanism, and when the mixing mechanism is stirring the raw materials of the concrete in the mixing drum, the rotating The mechanism makes the material inlet and outlet 45 of the mixing drum in a horizontal state.

[0068] Such as Figure 14 , 15 As shown, the installation method for the dust cover in the present invention is as follows: the end of the cover 1 in the dust cover away from the cover 2 is nested at...

Abstract

The invention belongs to the technical field of dustproof covers, and particularly relates to a dustproof cover used for a building engineering stirring machine. The dustproof cover comprises a coversleeve, a cover body, a heavy block, a strip swing plate, a volute spiral spring, a first incomplete bevel gear, a second incomplete bevel gear, a supporting lug, a cam and the like; a dustproof covercan be automatically opened when a feeding and discharging opening in a stirring cylinder needs to carry out feeding or discharging, in the stirring process of concrete raw materials in the stirringcylinder, the feeding and discharging opening in the stirring cylinder is covered by the dustproof cover, and therefore when the concrete raw materials are turned over in the stirring cylinder to cause a large amount of raw material dust, the dust cannot drop out of the feeding and discharging opening of the stirring cylinder and diffuse to the surrounding air, the phenomenon that the dropped-outraw material powder causes pollution to the surrounding air of the concrete stirring machine is avoided, and a certain environment-friendly effect is achieved; the structure is simple, and the good use effect is achieved.

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 ...
