Description

A feeding device for concrete raw materials

technical field

The utility model relates to the technical field of concrete production, in particular to a material unloading device for concrete raw materials.

Background technique

Since the current concrete raw material feeding device cannot screen out the large lumps that do not meet the processing requirements and the concrete raw materials, in the process of discharging the mixing station, these materials that do not meet the processing requirements and relatively large lumps will be screened out. Large lumps are directly discharged into the mixing station, which will affect the mixing efficiency of the mixing station for concrete raw materials.

For this reason, in the prior art scheme (notification number: CN213500060U) discloses a kind of material blanking device of concrete raw material, is all provided with agitating shaft by No. The 7-type rod rotates, so that the 7-type rod drives the crushing teeth to crush the concrete raw material lumps, so that the concrete is crushed finely to meet the standard of blanking, and the efficiency of later mixing and stirring of the concrete is improved. It can be seen from this technical solution combined with the drawings in the description that the method for crushing lumps is to use the crushing teeth to rotate, but because the screen is in an inverted V shape, part of the lumps will roll down to the screen. The junction of the net and the inner wall of the tank, and the position of the lowest end of the crushing teeth in the drawings of the instruction manual is obviously higher, which cannot crush the lumps, and also cannot completely break the lumps, resulting in accumulation, which also affects the flow of subsequent raw materials from the screen to the screen. Therefore, it is necessary to improve the existing technology to meet the actual needs.
