Description

Automatic concrete feeding device

Technical Field

The utility model relates to the technical field of concrete transportation, in particular to an automatic concrete feeding device.

Background Art

Concrete is abbreviated as "concrete". It refers to a mixture of cementitious materials and aggregates in appropriate proportions, which is hardened after a certain period of time. The commonly used raw materials include cement, fly ash, mineral powder, crushed stone, sand, water and water reducing agent. It has the characteristics of high hardness, high strength and good plasticity.

Infrastructure construction has always been an important support for social development. Concrete is an inevitable material in construction. In order to transport more quickly and save manpower, automatic concrete transport devices have emerged. At present, some automatic concrete transport devices are in a state of paste-like state and have a certain fluidity when working. When using a conveyor belt-like feeding mechanism to feed concrete, it is easy to cause concrete to fall from both sides of the conveyor belt, resulting in a waste of concrete and increasing the cost of users.

In addition, during the transportation process, concrete has a certain degree of adhesion, resulting in some concrete remaining on the surface of the conveyor belt after the feeding is completed. The existing device does not have the effect of cleaning the concrete. The concrete will always adhere to the surface of the feeding device. If the concrete is not cleaned in time, it will gradually petrify, thereby affecting the subsequent use of the feeding device.
