CLEAN DEVICE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device, and more particularly, to a cleaning device that can automatically and quickly clean the inside of a subject to be cleaned such as a concrete mixer using a mechanical device.

Generally, the method of producing concrete is a method in which the cement is directly mixed at a site to be poured, and a method of producing a ready mixed concrete produced by a batcher plant other than the site, To be transported to a loading site by a transporting vehicle and used in advance.

The batcher plant, which produces raw concrete, is a concrete batcher plant that mixes concrete materials such as cement, water, sand, gravel, and admixtures (chemicals) to produce concrete.

In a concrete batching plant, mixed water containing cement, aggregate, water and admixture is appropriately weighed according to the use of the concrete, and the weighed material is put into a mixer and mixed. This mixed concrete is conveyed to a construction site by a concrete hopper, which is placed in a waiting vehicle at the bottom of a concrete hopper.

In the conventional concrete production process, cement, water, sand, gravel and the like are put into a mixer in order to produce concrete. In a mixer, materials are mixed by a rotational force, then the discharge gate is opened and temporarily stored in a concrete hopper. The process proceeds to a series of processes in which a cylindrical chute is used to put it into a conveyance ready-mixed vehicle.

In this case, after mixing concrete, residual concrete of concrete and cement dust are adhered to the mixing arm, the mixing knife, the mixer surface, the ceiling of the mixer and the aggregate input port, and the water is washed with water to remove it .

However, conventionally, since the concrete adhered to the inside of the mixer is not completely removed, it is very troublesome that the worker must go inside the mixer and crush the concrete remnants directly with the punching tool. Therefore, There is a problem that time is wasted.

Conventionally, since the cleaning device for cleaning the mixer is installed in a fixed form inside the mixer, there is a problem that the cleaning nozzle is clogged due to the concrete residue and cement dust generated during the concrete production. Therefore, it is inconvenient to clean the washing device again, and it is inevitable that the upper inlet and cover of the mixer can not be cleaned.
