Description

Feeding device of brick making machine

Technical Field

The invention relates to the technical field of production of dutch bricks, in particular to a feeding device of a brick making machine.

Background

The Dutch brick is originated from the Netherlands, is a brick manufactured in the process of building a city by Netherlands in the sea, later, the American Shu Buluo Ke company is transformed to invent a pavement brick with a very strong water absorption function, which is called as a Shu Buluo Ke pavement brick, technical personnel in China in the nineties invent a pavement brick with water permeable holes and good water permeability according to the Shu Buluo Ke principle, crushed stones are used as raw materials, cement and a colloidal additive are added, and the brick is a water permeable brick used on municipal pavements. The dutch tiles have good water permeability, air permeability and water retention, and have multiple functions of cooling, noise reduction, climate regulation, air quality improvement and surface water circulation maintenance, are widely used for reconstruction of projects such as stations, airports, urban roads and the like, and become paving stones which are generally concerned and popular by people.

The existing Holland brick is generally divided into a base layer and a surface layer, wherein the base layer adopts dry and hard concrete as a raw material, the surface layer adopts wet concrete as a raw material, a brick making machine of the Holland brick firstly presses and forms and vibrates the fed dry and hard concrete, then inputs the wet concrete on the formed dry and hard concrete, and then presses and forms and vibrates the dry and hard concrete again by the brick making machine, and then outputs the Holland brick to be dried and maintained again. In the production process of the Holland bricks, the quality of some Holland bricks does not reach the standard, and waste can be caused by direct abandonment.

Disclosure of Invention

The invention aims to provide a feeding device of a brick making machine, which is used for recycling defective dutch bricks.

The technical purpose of the invention is realized by the following technical scheme: a feeding device of a brick making machine comprises a rack, wherein a conveyor belt used for conveying concrete is arranged on the rack and driven by a motor, a crusher fixed on the rack is further arranged above the conveyor belt, and an outlet end of the crusher is located right above the conveyor belt.

By adopting the scheme, when concrete is input into the brick making machine through the conveyor belt to make the Holland bricks, the inferior Holland bricks are smashed by the brick and stone smashing machine, smashed slag falls into the concrete on the conveyor belt below, and the concrete is sent into the brick making machine to make the Holland bricks, so that the inferior Holland bricks are recycled.

The invention is further configured to: the frame is also provided with a transmission belt which is arranged behind the crusher and used for conveying a layer of concrete to the transmission belt, and the transmission belt is positioned right above the transmission belt and driven by a motor.
