The first conduit 7 is fixedly installed with a regulating valve 11. The connecting pipe 8 is a three-way pipe or a two-way pipe, which is used to connect the first conduit 7 with the second conduits 9.

[0025] The upper end of the frame 2 is fixedly connected with a U-shaped seat 5, and the lower end of the horizontal section of the U-shaped seat 5 is provided with a scraper mechanism, which is arranged close to the plurality of discs 3. The scraper mechanism includes a hydraulic cylinder 12 fixedly installed at the upper end of the horizontal section at the center of the U-shaped seat 5, and the hydraulic cylinder 12 drives the lifting seat 13 to perform vertical lifting. The piston rod of the hydraulic cylinder 12 is arranged vertically downward, and the lower end of the piston rod of the hydraulic cylinder 12 is fixedly connected with the lifting seat 13, and the lower end of the lifting seat 13 is fixedly connected with a plurality of connecting blocks 14, and the lower ends of the plurality of connecting blocks 14 are vertically penetrated.

The hydraulic cylinder 12 and the pump body 6 on the U-shaped seat 5 are started by the external PLC controller, so that the hydraulic cylinder 12 cooperates with the lifting seat 13 to drive the scrapers 15 at the lower ends of the plurality of connecting blocks 14 to rise and fall vertically, and the plurality of scrapers 15 are used to scrape the side walls of the plurality of discs 3 that are closely attached, and the minerals attached to the plurality of discs 3 fall into the drainage trough 4 along with the scraping of the scrapers 15, and at the same time, the pump body 6 guides the external water into the plurality of second conduits 9 through the first conduit 7 and the plurality of connecting pipes 8, and the plurality of second conduits 9 cooperate with the spray nozzles 10 to remove the external water. Water is sprayed between two adjacent discs 3, so that the scraped ore and the sprayed water are discharged along the drainage groove 4, which is convenient for timely cleaning of the ore attached to the disc 3. When the recovery machine body 1 vibrates during operation, the columnar block 17 at the lower end of the mounting plate 16 is forced to compress the circular buffer block 21 in the sleeve base 18. On the one hand, the circular buffer block 21 compresses the hydraulic buffer 20 in the sleeve base 18, and on the other hand, compresses the air in the sleeve base 18, so that the compressed air is slowly discharged along the air vent 22 in cooperation with the valve 23, thereby effectively buffering the force on the columnar block 17, and cooperating with the pad 19 of the artificial cartilage energy-absorbing material to provide vibration reduction and buffering for the recovery machine body 1, thereby reducing the noise generated during the operation of the recovery machine body 1, and having a good vibration reduction and noise reduction effect.
