[0002] Chinese Patent with application number 202322604675.4 discloses an efficient asphalt concrete crushing device. Through the coordinated use of a dust extractor, a dust extraction duct, a water pump, a drain pipe, and an atomizing nozzle, it can use the dust extractor and the dust extraction duct to extract the dust in the crushing box into the dust collection box, avoiding the situation of dust splashing everywhere. At the same time, with the spraying of the drain pipe and the atomizing nozzle, it can play a dust reduction effect in the dust collection box, reducing the environmental pollution caused by dust and ensuring the physical health of the staff.

[0026] Working principle: When the electrical components appearing in this application are in use, they are externally connected to a power source and a control switch. After this utility model is installed, first check the installation and fixation as well as the safety protection of this utility model, and then it can be used. When in use, the staff places the collection shell 4 under the mounting rack 1, inserts the T-shaped block 6 into the T-shaped groove 5 in alignment, so that the collection shell 4 is arranged under the discharge port 10, and then pours the asphalt blocks to be crushed into the feed hopper 11.

The first half gear 78 and the second half gear 79 are successively engaged with the tooth block 710, driving the tooth block 710 to move reciprocally, so that the tooth block 710 drives the inner rod 711 to move synchronously. The inner rod 711 drives the collection box 7 to shake in the collection shell 4 through the connecting block 713, so that the internal materials are shaken, and the materials are laid more evenly on the inner bottom of the collection box 7, with relatively strong practicability.
