Description

Technical Field

[0001] The utility model belongs to the technical field of concrete crushing, and in particular relates to a concrete crushing device. Background Art

[0002] At present, concrete is an indispensable material in the construction industry. There are many discarded concrete blocks in many places. In order to recycle the concrete blocks, crushing devices are used to crush them.

[0003] For example, the Chinese patent with the publication number CN213254685U discloses a concrete crushing device, including a shell, the top of the shell is connected to a feed port, the bottom of the shell is connected to a discharge port, the side of the shell is connected to a first connecting plate, the top of the first connecting plate is connected to a second connecting plate, the side of the second connecting plate is connected to a heat dissipation motor, the output end of the heat dissipation motor is connected to a heat dissipation fan, and the side of the shell is connected to a vent. The length of the first crushing wheel is greater than the length of the feed port, ensuring that the concrete can be initially crushed. The heat dissipation motor drives the heat dissipation fan to rotate, which can cool the inside of the shell and reduce the dust generated during crushing. The liquid in the water tank reaches the water mist generator through the water pump and forms water mist, which can cool the first and second crushing wheels on the one hand, and remove the dust generated during crushing on the other hand, ensuring that no secondary pollution will be caused.

[0004] When the existing concrete crushing device is used, the concrete powder needs to be graded and screened, but the screen is easily blocked, resulting in low screening efficiency. In view of this, we propose a concrete crushing device. Utility Model Content

[0008] In the present technical scheme, the vibration equipment drives the screening chassis, the subdivision frame and the coarse classification frame to vibrate, and the concrete is graded and screened through the second screen and the first screen. The screened concrete is discharged from the discharge guide plate. Then, the second screen and the first screen are cleaned, and the staff drives the sliding plate to slide along the outer wall of the guide rail. The sliding of the sliding plate drives the cleaning brush to clean the concrete in the second screen and the first screen. Then, the positioning spring drives the lifting orifice plate to slide through its own elastic force, and the sliding of the lifting orifice plate drives the telescopic block to slide along the inner wall of the positioning frame through the connecting column.
