Stirring device for building materials

Abstract

The invention relates to the technical field of processing of building materials and particularly relates to a stirring device for the building materials. The stirring device comprises a stirring shaft and a rotary blade arranged on the stirring shaft, wherein a plurality of limiting seats sleeve and are fixed on the stirring shaft; the rotary blade is fixedly connected with the stirring shaft by the limiting seats and extends outwards to form a sector shape; the side surface of the rotary blade is a plane and is parallel to the axis of the stirring shaft; a flexible rubber piece is fixed on the outer edge of the rotary blade, and is fixed with the rotary blade by a rivet; and a plurality of through holes are uniformly distributed on the rotary blade at intervals. The stirring device adopting the technical scheme has the advantages of convenience in installation and disassembly, good stirring effect and long service life.

Description

technical field [0001] The invention relates to the technical field of building material processing, in particular to a building material stirring device. Background technique [0002] At present, the processing of building materials, especially the mixing of concrete materials often requires the use of stirring devices. Most of the stirring blades of the stirring device are made of metal materials as a whole, so the weight of the blades is very large, and it is inconvenient to install, disassemble and maintain; in addition, Because there are many particles such as stones and sand in the concrete, it is necessary to add wear-resistant materials on the surface of the blades to effectively reduce wear and prolong the service life. Due to the high wear-resistant materials, the cost of the mixing blades is relatively high. In addition, due to the relatively hard metal of the stirring blade, when working in the hopper, the gap between the stirring blade and the bottom of the hopp...

Problems solved by technology

[0002] At present, the processing of building materials, especially the mixing of concrete materials often requires the use of mixing devices. Most of the mixing blades of the mixing devices are made of metal materials as a whole, so the weight of the blades is very large, and it is inconvenient to install, disassemble and maintain; in addition, Because there are many particles such as stones and sand in the concrete, it is necessary to add wear-resistant materials on the surface of the blades to effectively reduce wear and prolong the service life. Due to the high wear-resistant materials, the cost of the mixing blades is relatively high.

In addition, due to the relatively hard metal of the stirring blade, when working in the hopper, the gap between the stirring blade and the bottom of the hopper needs to be large enough to prevent the bottom of the hopper from being worn; at the same time, the gap between the stirring blade and the bottom of the hopper should not be too large , because it will affect the mixing effect of concrete at the bottom of the hopper, and finally affect the strength of building materials
