Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, and more specifically to a construction waste crusher. Background Art

[0002] There are many types of crushers. Jaw crusher is a type of crusher commonly used in construction waste. Jaw crusher is a type of crusher. The motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft assembly. When the movable jaw rises, the angle between the toggle plate and the movable jaw increases, thereby pushing the movable jaw plate closer to the fixed jaw plate. At the same time, the material is crushed or split to achieve the purpose of crushing. The crushing method of this series of crushers is the flexural extrusion type. When the movable jaw goes down, the angle between the toggle plate and the movable jaw decreases. The movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. At this time, the crushed material is discharged from the lower opening of the crushing chamber. As the motor rotates continuously, the movable jaw of the crusher periodically crushes and discharges materials to achieve mass production.

[0003] Problems with existing construction waste crushers:

[0004] First, the dust generated by the crushed waste will cause environmental pollution. When some stones are crushed, some crushed stone powder will be produced. The crushed stone powder is easy to cause the powder to fly under the vibration of the device, which is easy to pollute the environment and cause harm to the lungs of the workers.

[0005] Secondly, the size of the waste after being crushed by the movable jaw plate and the fixed jaw plate is uneven, and some of the waste is not crushed thoroughly enough to meet the technical requirements of crushing, so it needs to be taken out for secondary processing, which affects work efficiency.
