CRUSHING DEVICE WITH LARGE-VOLUME CONCRETE AGGLOMERATION SCREENING AND CRUSHING FUNCTIONS

The invention discloses a crushing device with mass concrete caking screening and crushing functions, the crushing device comprises a treatment box, a screening tank is rotatably mounted at the top of the treatment box, the bottom of the screening tank extends into the treatment box, and a screening mechanism is arranged in the screening tank; the screening mechanism comprises a semi-conical cover plate, a plurality of coarse holes, a plurality of fine holes, a cylinder, a plurality of blanking holes, a first outer gear ring, a first motor, a driving rod and a first gear, the semi-conical cover plate is fixedly mounted in the screening tank, the coarse holes are all formed in the semi-conical cover plate, the fine holes are all formed in the bottom of the semi-conical cover plate, and the first outer gear ring is fixedly mounted in the cylinder. The invention relates to the technical field of construction waste. According to the crushing device with the large-volume concrete caking screening and crushing functions, large-volume caking in construction waste can be separately screened out through the arranged screening mechanism, so that the large-volume caking can be preliminarily crushed, and the crushing speed of the large-volume waste can be increased.
