Description

A kind of concrete crushing and recycling equipment

technical field

The utility model relates to the technical field of construction equipment, in particular to a concrete crushing and recycling equipment.

Background technique

Concrete recycling equipment refers to the new concrete made by crushing, cleaning and grading waste concrete blocks, mixing them with gradation in a certain proportion, replacing part or all of natural aggregates such as sand and gravel, and then adding cement, water, etc. Generally, concrete has a long service life, but after a period of use, concrete structures or buildings will be demolished, resulting in a large amount of waste concrete. Now the traditional treatment method of waste concrete is mainly to transport it to the suburbs for burial. This treatment method not only wastes soil, but also pollutes groundwater with the erosion of rainwater, and there is no specific equipment to crush concrete in the existing concrete regeneration scheme. In addition, it wastes manpower, and the processing cost is high, which is not convenient for personnel management in the later stage.

The patent number is CN201920129891.9, which discloses a concrete crushing and recycling equipment, including a frame and a screening frame arranged in the frame, the upper end of the frame is provided with a feeding port, and the lower part of the frame is provided with an outlet. The feeding port is provided with a rotating shaft, and the rotating shaft is provided with an impeller knife, and a pair of radially arranged crushing plates are arranged in the frame and located between the feeding port and the screening frame. The crushing plates are slidably arranged relative to each other along the horizontal direction or opposite to each other, and the opposite ends of the crushing plates extend and slide and are inserted into the power rod on the frame. The above-mentioned patent only uses the crushing plate to crush the concrete, but the concrete cannot be crushed completely, and the crushing cannot effectively crush the concrete into the required particle size, and there is no subsequent crushing of the concrete after simple crushing. Treatment device, resulting in the concrete recycling equipment still has major defects.

For the problems in the related technologies, no effective solutions have been proposed so far.
