The invention discloses a concrete recovery and crushing device based on the recycling of urban construction waste, which includes a casing, a vibrating motor, a stepping motor, a first motor, a second motor, and a control panel. The middle position of the casing is welded and fixed with a preset The broken bin, and the outer walls of the front and rear sides of the pre-shredded bin are respectively symmetrically hinged with tooth sleeves, and the middle position of each set of the tooth sleeves is fixedly inlaid with a threaded sleeve, and a first screw is inserted inside the threaded sleeve. In the present invention, the thread sleeve is connected with the first screw thread to rotate, so that the tooth sleeve can drive the movement of the restricting rod through the meshing of the thread when rotating, and cooperate with the start-up vibration of the vibration motor, so that the crushing knife can carry out the crushing on the concrete block entering the pre-crushing bin. Extrusion crushing is conducive to improving the efficiency of crushing concrete blocks, and effectively prevents the excessive volume of concrete blocks from grinding machinery during crushing, which is beneficial to prolonging the service life of the device.
Description
technical field [0001] The invention relates to the technical field of concrete recycling and crushing equipment for urban construction, in particular to a concrete recycling and crushing device based on the recycling of urban construction waste. Background technique [0002] Concrete refers to cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. Artificial stone, in the existing urban building construction, there is usually a small amount of concrete remaining, because the remaining concrete coagulates into blocks after being placed for a long time, causing the concrete to fail, and if it is directly discarded, it will cause a lot of waste. Therefore, it is usually used The crushing unit recycles the concrete. [0003] The existing crushing device for concrete recovery usually adopts crushing rollers arranged opposi...
