Each auxiliary assembly 32 comprises a first auxiliary pipe 321 and a second auxiliary pipe 322, one end of each first auxiliary pipe 321 and one end of each second auxiliary pipe 322 are communicated with one end of the connecting header pipe 312, the ends of the first auxiliary pipe 321 and the second auxiliary pipe 322 are respectively located at two sides of the dissolving tank 1, the ends of the first auxiliary pipe 321 and the second auxiliary pipe 322 are respectively provided with a plurality of water spray heads 323, the water spray heads 323 on the first auxiliary pipe 321 are all arranged towards the upper part of the stirring shaft 241, the water spray heads 323 on the second auxiliary pipe 322 are all arranged towards the lower part of the stirring shaft 241, each connecting header pipe 312 is provided with a second control valve 324, and the second control valves 324 are located at the rear part of the communication part of the connecting header pipe 312 and the connecting branch pipe 313; when the water pump 311 works, the first control valve 314 closes the connecting branch pipe 313, and the second control valve 324 opens the tail end of the connecting main pipe 312, the solution pumped out by the water pump 311 flows to all the water spray heads 323 through the first auxiliary pipe 321 and the second auxiliary pipe 322, and the water column sprayed by the water spray heads 323 washes the outside of the dissolving shell 212, on one hand, impurities of the rare earth ore can be prevented from being clamped in meshes on the dissolving shell 212, on the other hand, the water spray heads 323 work to form water flow, the stirring component 24 can be driven to rotate, meanwhile, the water flow can drive the rare earth ore to turn over, so that stirring is realized, and the reaction speed of the rare earth ore and the solution is improved.

The four striker plates 6 are arranged at the feed port 224, one sides of the four striker plates 6 are rotatably connected with the turnover shell 211, one side of each striker plate 6 is provided with a limiting ridge 7, and a limiting block 8 is arranged above each striker plate 6; when upset shell 211 is located the top of dissolving shell 212, four striker plates 6 are the tilt state under the action of gravity, make feed inlet 224 open, when dissolving shell 212 is located the top of upset shell 211, four striker plates 6 all are the horizontality, can be closed feed inlet 224, avoid rare earth ore to pour out from feed inlet 224, wherein, the effect of restriction stupefied 7 is to avoid striker plate 6 to be vertical state, when dissolving shell 212 and rotating to the top of upset shell 211 like this, striker plate 6 can rotate to the horizontality under the action of gravity owing to be the slope, the setting of restriction piece 8 is, when feed inlet 224 sets up down, all striker plates 6 all can rotate to the horizontality, avoid striker plate 6 turned angle too big to lead to feed inlet 224 unable closure.

The working principle of the invention is as follows: when in use, the rare earth ore is added into the dissolving shell 212 through the feed hopper, the corrugated pipe 222 and the feed pipe 223, the dissolving shell 212 is positioned in the third dissolving tank 13, so that the newly added rare earth ore reacts with the low-concentration solution after two times of use, then the turnover motor 217 works to drive the turnover shaft 215 to rotate, the turnover shaft 215 drives the turnover gear 216 to rotate, the turnover gear 216 drives the turnover teeth 214 and the turnover block 213 to rotate, further the turnover shell 211 and the dissolving shell 212 are driven to rotate, the dissolving shell 212 rotates to the upper part of the turnover shell 211, the rare earth ore in the dissolving shell 212 falls into the turnover shell 211, the driving gear 232 is driven to rotate through the transmission of the conveying motor 231, the driving gear 232 drives the driven gear 233 to rotate through the transmission of the belt, further the conveying shaft 234 drives the spiral vane 235 to rotate, the rare earth ore in the turnover shell 211 is conveyed forwards, and at the same time, through the cooperation of water pump 311, connecting main 312 and connecting branch 313, can be with in the solution conveyer belt second dissolving tank 12 in the first dissolving tank 11, in the solution conveyer belt third dissolving tank 13 in the second dissolving tank 12, discharge the solution in the third dissolving tank 13, the setting of first control valve 314 is the closure that is used for control connection branch 313, afterwards, upset subassembly 21 reworks, fall the rare earth ore in the shell 211 that overturns in dissolving the shell 212, and react with the solution in the dissolving tank 1 that corresponds, pass through at last, conveying subassembly 23 is discharged impurity from the discharge gate.
