Technical Field

[0001] The utility model relates to the field of ore separation, in particular to a rare earth metal ore re-selection device. Background Art

[0002] The world has huge reserves of rare earth resources. In the process of mining these rare earth metal ores, the minerals are generally closely coexisting with other associated minerals, and the embedded particle size is fine, so the ore needs to be finely ground to dissociate the rare earth mineral monomers. The existing ore re-selection device uses the principle of different densities of different ores to drive the ore to screen out the ore through water flow, while the mixing of ore and water only relies on the impact of water flow, and the mixing of ore and water is not sufficient, which leads to low efficiency of re-selection. Utility Model Content

[0004] The technical solution of the utility model is: a rare earth metal ore re-selection device, comprising a base, a sliding bracket fixedly connected to the base, a rocking frame slidably connected to the sliding bracket, a plurality of transverse grooves on the rocking frame, a hydraulic push rod fixedly connected to the sliding bracket, a telescopic rod of the hydraulic push rod fixedly connected to one side of the rocking frame, a water supply pipe fixedly connected to one side of the sliding bracket, a guide frame fixedly connected to the side of the rocking frame close to the water supply pipe, a plurality of circular holes on the bottom of the guide frame, a discharge hopper fixedly connected to the water supply pipe, the discharge hopper is located above the guide frame, and an auxiliary discharge mechanism is provided on the discharge hopper.

[0005] In one of the embodiments, the auxiliary discharge mechanism includes a swing plate, and the swing plate is rotatably connected to the discharge hopper.

[0006] In one of the embodiments, the auxiliary discharging mechanism also includes a column gear, the column gear is fixedly connected to the swing plate, a gear rod is fixedly connected to the rocking frame, the gear rod is located below the column gear, and the gear rod is meshed with the column gear.

[0007] In one of the embodiments, the auxiliary discharge mechanism also includes a sliding frame, two of the sliding frames are fixedly connected to the top of the discharge hopper, the two sliding frames are symmetrically arranged, and both of the sliding frames are slidably connected with a scraper frame, and two transmission rods are fixedly connected to the swing plate, the two transmission rods are symmetrically arranged, and both of the transmission rods have a S-shaped groove, the scraper frame and the transmission rod on the same side are slidably connected, and the scraper frame and the transmission rod on the same side are a group.

[0008] In one of the embodiments, a plurality of circular holes are formed on the swing plate.

[0009] The beneficial effects are: 1. When the shaking frame vibrates, the gear rod on the shaking frame will drive the column gear to rotate forward and reverse, and the swing plate with the column gear will swing back and forth. In this way, when the staff introduces the ore into the discharge hopper, the swing plate swings back and forth to fully mix the ore and water, which can avoid the accumulation of ore and improve the efficiency of gravity separation.

[0010] 2. When the swing plate swings back and forth, it drives the two transmission rods to swing back and forth. The swing of each group of transmission rods will drive the scraper frames of the same group to scrape back and forth in the hopper, so as to avoid the accumulation of mineral materials on the inner wall of the hopper and improve the efficiency of gravity separation.

[0020] At first, the staff starts the hydraulic push rod 4, which drives the shaking frame 3 to move back and forth quickly. Then the staff passes water into the water supply pipe 5, and the water flows into the discharge hopper 7 through the water supply pipe 5. Then the staff pours the mineral material to be re-selected into the discharge hopper 7, so that the mineral material will be driven by the water flow to flow into the guide frame 6, and the water flow carrying the mineral material flows to the shaking frame 3 through the holes opened at the bottom of the guide frame 6. The rapid reciprocating movement of the shaking frame 3 will drive the mineral material to vibrate. Due to the different densities of different mineral materials, under the joint action of the vibration of the shaking frame 3 and the horizontal grooves on the shaking frame 3, the mineral material in the water flow will appear in the form of bands as it flows with the water flow, and different types of ores are in different bands. In this way, the re-selection of the mineral material is completed, and the staff only needs to collect the sorted mineral material.

[0024] The swing plate 8 is provided with a plurality of circular holes, and the circular holes can reduce the resistance caused by water when the swing plate 8 swings.

[0025] When the hydraulic push rod 4 drives the shaking frame 3 to vibrate, the gear rod 10 on the shaking frame 3 will drive the column gear 9 to rotate forward and reversely, and the column gear 9 drives the swing plate 8 to swing back and forth. In this way, when the staff pours the ore into the discharge hopper 7, the swing plate 8 swings back and forth to fully mix the ore and water, so that the phenomenon of ore accumulation can be avoided and the gravity separation efficiency is improved.

[0026] When the swing plate 8 swings back and forth, the swing plate 8 drives the two transmission rods 13 to swing back and forth. The swing of each group of transmission rods 13 will drive the scraper frame 12 of the same group to scrape back and forth in the discharge hopper 7, so as to avoid the accumulation of mineral materials on the inner wall of the discharge hopper 7 and improve the efficiency of gravity separation.
