Description

A feeding device for concrete production

Technical Field

The utility model relates to the technical field of concrete equipment, in particular to a material feeding device for concrete production.

Background technique

Currently in the construction field, concrete is a common building material. Concrete is made by mixing sand, gravel and mud. Sand, gravel and mud are poured into a mixing device for mixing and then discharged to a receiving device for placement. When the concrete is needed, it can be directly taken from the receiving device.

The existing concrete unloading device serves as a transition device to transfer the mixed concrete to the receiving device or directly to the target mold cabinet for molding. The unloading device generally includes a unloading barrel, which is provided with a feed port and a discharge port. The feed port is connected to the raw material mixing device. During operation, the mixing device transports the mixed concrete to the unloading device for storage. When it is needed, the material is received from the unloading device for use.

The above-mentioned prior art solutions have the following defects: when the concrete is unevenly mixed in the mixing device, large particles of agglomerates will appear in the concrete when it transitions to the mixing device, and stratification and precipitation are more likely to occur, which affects the discharge quality of the feeding device and ultimately affects the quality of the product, and improvements are needed.

Summary of the invention

The purpose of the utility model is to provide a material feeding device for concrete production, so as to solve the above-mentioned defects caused by the prior art.

The cam is an axially movable device for conveying materials to the conveyor belt, and the cam is connected with the gear train of the conveyor belt to move upwards to move the cam, and the cam is connected with the gear train of the conveyor belt to move upwards to move the cam, so that the cam can move upwards and downwards to move the cam.

Preferably, a plurality of supporting legs are vertically connected to the lower side of the mounting bucket, and a supporting plate is horizontally welded to the lower end of the supporting leg.

Preferably, a rubber pad is connected to the lower side of the support plate.

Preferably, a plurality of scrapers are evenly connected to the lower side of the impeller, and the blades of the scrapers are in sliding contact with the inner wall of the mounting bucket.

Compared with the prior art, the utility model has the following advantages:

The motor drives the impeller to rotate through the first mounting shaft. The impeller continuously stirs the concrete in the lower barrel during rotation, and rolls the concrete in the lower layer to the upper layer, thereby preventing the concrete in the lower barrel from stratifying and settling. At the same time, the motor drives the stirring bar to rotate through the second mounting shaft. The stirring bar continuously stirs the concrete in the lower barrel during rotation, and mixes the concrete in the lower barrel evenly, thereby preventing the concrete in the lower barrel from agglomerating.
