Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a movable impact crusher for construction waste treatment. Background Art

[0002] Construction waste refers to the general term for muck, waste concrete, waste bricks and stones and other solid wastes generated in the production activities of the construction industry such as demolition, construction, decoration, and repair; if these solid wastes are not treated and utilized in time, they will surely have an adverse impact on society, the environment and resources; at the same time, because they have a certain recycling value, construction waste is usually recycled and reused. The process of recycling and reuse is to first evenly feed the construction waste into a jaw crusher for primary crushing. The semi-finished product after primary crushing is transported to an impact crusher by a belt conveyor for further crushing. The crushed stone after secondary crushing is transported to a vibrating screen by a belt conveyor. Aggregates of different specifications are screened out. The aggregates that meet the particle size requirements of customers are transported to the finished product stockpile by a belt conveyor. The aggregates larger than the size of the upper screen mesh are transported back to the impact crusher by a belt conveyor for re-crushing, forming a closed circuit cycle to complete the processing of the aggregates. It can be seen from the process that the impact crusher is a mechanical equipment that can be reused, and thus its importance can be seen. The impact crusher is a mechanical equipment that realizes the crushing effect by the impact energy of the high-speed rotating rotor and the material.

[0003] For example, Chinese Patent No. CN 220443971 U discloses an impact crusher. The vibration motor, the first hydraulic driving device and the second hydraulic driving device are controlled by a control box to work. The material to be crushed is put into the shell through the feeding port. After the rotor assembly works to perform primary crushing on the material, the crushed material is bounced to the first impact frame and the second impact frame and then is crushed again by the plate hammer and the crushing block until the crushed material is discharged from the sieve plate. The vibration motor drives the telescopic rod to drive the sieve plate to vibrate, causing the sieve plate to vibrate, facilitating the material to fall into the discharge port from the discharge hole. The sieve plate is vibrated and shock-absorbed through the vibration assembly and the buffer, avoiding the possible situation of material jamming on the sieve plate, and separating the material blocked at the top of the sieve plate from the sieve plate, avoiding the blockage of the sieve plate and affecting the passing of the material with qualified particle size. Although the invention realizes avoiding material jamming, the material with a particle size larger than the aperture will stay at the top of the sieve plate and is easy to cause blockage, which is not conducive to the passing of the qualified material.
