Concrete preparation device and use method thereof

Abstract

The invention discloses a concrete preparation device in the technical field of concrete preparation, the concrete preparation device comprises a base, a conveying belt, a first crushing assembly, a second crushing assembly and a screening box, a screening assembly and a material pushing assembly are arranged in the screening box, inclined discharging grooves are formed in the two sides of the interior of the screening box, and the outer side ends of the two discharging grooves are jointly connected with a material collecting pipe; materials are conveyed into the first smashing assembly to be smashed for the first time and then enter the screening box, the materials are screened through the screening assembly, and the materials which do not pass through screening are pushed to the two sides of the screening assembly through the pushing assembly and fall into the discharging groove, so that the situation that too much materials are accumulated on the screening assembly, and follow-up screening is affected is avoided; and the materials enter the second crushing assembly to be subjected to secondary crushing, the particle size of the materials is reduced, the materials which do not pass through screening can be recycled in time, the material transferring operation is reduced, and material preparation and treatment are faster and more convenient.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to a concrete preparation device and a use method thereof. Background technique [0002] During the production and preparation of concrete, it is necessary to pulverize and screen its constituent materials so that the materials can reach the appropriate particle size. Patent No. CN202021387856.6 A kind of high-efficiency crushing recycled concrete crushing and screening device, including crushing area and screening area, crushing area is provided with crushing roller, crushing area is provided with upper sieve plate and lower sieve plate, upper sieve plate The rotating shaft is connected with a rotating shaft, and the rotating shaft is provided with a screw crushing blade for crushing waste concrete, which can crush and screen concrete materials. Pulverization, insufficient pulverization, and there is no pulverizing structure on the lower sieve plate, the materials tha...

AI Technical Summary

Problems solved by technology

Patent No. CN202021387856.6 is a high-efficiency crushing recycled concrete crushing and screening device, including a crushing area and a screening area. There are crushing rollers in the crushing area, and an upper screen plate and a lower screen plate in the crushing area. The upper screen plate The rotation is connected with a rotating shaft, and the rotating shaft is equipped with a spiral crushing blade for crushing waste concrete, which can crush and screen concrete materials. Crushing, insufficient crushing, and there is no crushing structure on the lower sieve plate, the materials that have not passed the screening are accumulated on the upper sieve plate and the lower sieve plate, and the number gradually increases, which will affect the subsequent screening
