Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, and specifically relates to a concrete raw material crushing device for processing concrete recycled bricks. Background Technique

[0002] Recycled aggregates can be applied to cement concrete, asphalt concrete, road bases, railway ballast, etc. In the laying of the park, the addition of aggregates can beautify the park. Therefore, a concrete raw material crushing device for processing concrete recycled bricks is needed.

[0003] According to a concrete crushing device disclosed on the patent network (authorization announcement number: CN 219559782 U), it is described that "the utility model relates to the technical field of concrete crushing, and specifically relates to a concrete crushing device, including a crushing box, and a groove is opened at the top of the crushing box. The advantages are as follows: by setting a moving plate, when in use, the concrete block material is fed into the inside of the moving plate through a feeding plate and falls onto the crushing roller. Then, the baffle is moved to the bottom of the feeding plate to seal the feeding port, and the concrete can be crushed by the crushing roller. The crushed material falls to the bottom of the crushing box and is discharged. During the crushing process, as the material on the top of the crushing roller decreases, the air cylinder is started, so that the push rod pulls the push plate downward, driving the moving plate and the baffle to move downward together. At the same time, the positioning plate moves inside the groove for positioning. During the moving process, the baffle pushes the material on the top of the crushing roller downward, making the material move between the two crushing rollers, reducing the movement of the concrete block on the crushing roller, accelerating the crushing speed, and improving the work efficiency".

[0004] Regarding the above description content, the applicant believes that there are the following problems: when the device is in use, the concrete block material is fed into the inside of the moving plate through the feeding plate and will fall onto the crushing roller.
