Shaftless spiral material mixing, stirring and feeding machine

Abstract

The invention belongs to a shaftless spiral material mixing, stirring and feeding machine. The shaftless spiral material mixing, stirring and feeding machine comprises a base, a main stirring shell, amain shaftless spiral and a power assembly. The main stirring shell is arranged on the base in a supporting manner. Multiple feeding bins are arranged on the main stirring shell. The feeding bins include the first feeding bin and the second feeding bin. A discharge port is formed in the end portion of the main stirring shell. The main shaftless spiral is arranged in the main stirring shell in a matched manner. The main shaftless spiral is of a sectional type structure. The main shaftless spiral at least comprises a first main spiral section and a second main spiral section. The first main spiral section and the second main spiral section correspond to the first feeding bin and the second feeding bin correspondingly. The formed shaftless spiral material mixing, stirring and feeding machineis compact in structure, convenient to move and free of bonding and does not need to be cleaned, the guniting work efficiency is improved, the guniting work labor intensity is lowered, and the spraying quality is improved.

Description

technical field [0001] The invention belongs to a shaftless spiral batching stirring feeder, in particular to a shaftless spiral batching stirring feeder. Background technique [0002] At present, the tidal spraying process is mostly used in the underground operation of coal mines, and the rotor concrete spraying machine is used for spraying. When carrying out concrete spraying support operations in coal mines, for most coal mines in China, due to the narrow space of the roadway, large-scale concrete batching, mixing, and feeding equipment cannot be used, and there are still many manual batching, manual mixing, and manual feeding. In this way, the labor intensity of workers is high and the work efficiency is low. At the same time, manual mixing and feeding will cause a lot of dust, which will affect the health of workers; and manual mixing will not ensure uniformity, resulting in large spray rebound and serious waste. Some coal mines use screw feeders to realize automatic ...

AI Technical Summary

Problems solved by technology

However, the use of a shaft screw feeder is relatively good for dry spraying construction. When it is suitable for tidal spraying, cement must be used as a raw material for spraying, resulting in serious adhesion on the screw blades of the shaft screw, which lasts for a long time. After use, the efficiency is seriously reduced, and it needs to be cleaned frequently, which is time-consuming and laborious; in view of the different working conditions and construction techniques of underground coal mine operations, it is necessary to further optimize the process of batching, feeding and mixing, so as to further improve work efficiency and Jetting quality, which enables the whole process to be implemented with high quality and high efficiency
