Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, in particular to a crushing device for building concrete blocks. Background Art

[0002] There are many solid wastes in construction sites, among which concrete waste is the most numerous and difficult to handle. The accumulation of concrete waste limits the construction conditions on the construction site and affects the construction efficiency. The cone crusher is a mining machine used to crush stones. Its working principle is to drive the eccentric rotation of the movable cone main shaft group through the eccentric mechanism. The movable cone liner on the movable cone main shaft group and the fixed cone liner on the fixed cone frame cooperate with each other to crush stones, which can quickly and thoroughly handle concrete waste.

[0003] However, a large amount of concrete dust will be generated during the stone crushing process. The existing cone crusher does not process the dust generated by the waste when crushing concrete waste. The dust causes blockage and jamming inside the equipment and air pollution, affecting the working efficiency of the device. In addition, during the stone crushing process, the existing cone crusher will generate a huge load, and the rigidly connected fixed cone liner will cause the frame to vibrate strongly. The frame is prone to cracks due to long-term vibration and collision with stones, which seriously affects its service life.

[0004] Therefore, we have made improvements to this and proposed a crushing device for building concrete blocks. Summary of the Invention

[0017] 1. By opening slots at equal intervals on the feed hopper and the mortar wall, and installing the humidifying mechanism embedded in the fixed cone through the slots, the clean water at the bottom of the crusher shell is sprayed out in the form of high-pressure water mist through the humidifying mechanism to humidify the mortar wall, the moving cone and the soil blocks in the crushing process.

The provided buffer rack and frame can reduce the loss of the structure to the vibration during operation and extend the service life of the equipment.

[0019] 3. By connecting the filtering mechanism with the buffer frame, the buffer frame transmits the vibration generated on the moving cone to the filtering mechanism, and the remaining vibration amplitude drives the swing frame to shake.
