In the present embodiment, as shown in fig. 1, the bottom of the support housing 110 is provided with a discharge opening 130. While the small pieces of ore that have been qualified will fall through the vibrating screen deck fine screen 430 into the lowermost chamber, be rotated by the third spring-pusher plate 443 and finally discharged from the discharge opening 130.
In the initial state, the coarse mesh 420 is in contact with the first metal contact 111, and the fine mesh 430 is in contact with the third metal contact 113. The long helical lifts 330 and the short helical lifts 340 do not mate with a certain spacing therebetween.
Starting the second motor, the special main shaft 410 starts to rotate around its own axis and the crushing cone 210 starts to swing eccentrically due to the action of the tilt shaft guide 413. Large molybdenum ore is thrown into the support shell 110 from the feed cylinder 120, falls into the gap between the feed cylinder 120 and the crushing cone 210, and the crushing cone 210 crushes molybdenum ore in the gap circumferentially.
The crushed ore moves downwardly from the gap between the feed cylinder 120 and the crushing cone 210 and falls onto the screening deck coarse screen 420, at which point the spring support plate 450 is compressed, the coarse screen 420 moves downwardly, the first link 351 moves downwardly, driving the gear 352 to rotate, and thus causing the link to move upwardly and driving the long helical lifts 330 to move upwardly. Since the first spring-pulling plate 441 circumferentially rotates along with the special main shaft 410, small ore pieces and medium-sized ore pieces fall downward from the holes of the coarse screen 420 under the pushing action of the first spring-pulling plate 441, and large ore pieces are pushed in the direction of the long spiral lifting 330 in the rotating process. The first motor 320 is activated to rotate the long screw lift 330, and under the action of the long screw lift 330, the large ore is transported to the upper end of the long screw lift 330 and is crushed again after being transported again into the feed cylinder 120 through the discharge port 460.
The medium ore falls onto the fine screen 430 and is temporarily stored above the fine screen 430 until the large ore pieces above the coarse screen 420 are processed. In the process, more and more medium ores fall into the fine screen 430, and under the action of the ratchet ring 411, the ratchet ring 411 rotates along with the special spindle 410, so that the fine screen 430 starts to vibrate. Then a portion of the small particle ore falls, the small pieces pass through the fine screen 430 and finally reach the bottom of the support shell 110, the medium particle ore is gradually accumulated on the fine screen 430, the fine screen 430 is gradually pressed to move downwards, and the first spring is compressed. The fine screen 430 moves downward and the short spiral lifts 340 gradually move upward by the second link 361. But the long spiral lifts 330 and the short spiral lifts 340 remain untouched.
Until the large ore above the coarse screen 420 is processed, the compressed spring support 450 is released, the coarse screen 420 returns to the initial position to contact the first metal contact 111, the first link 351 moves upward to drive the gear 352 to rotate, and the link moves downward to drive the long spiral lifting 330 to move downward. Finally, the matching block on the long spiral lifting body 330 is inserted into the matching opening 342 on the short spiral lifting body 340, the lower end of the long spiral lifting body 330 contacts the fifth metal contact 341, the fifth metal contact 341 is connected with the circuit through the coil inside the fifth metal contact 341 to form an electromagnet, and the short spiral lifting body 340 and the long spiral lifting body 330 are tightly fixed. While the mating opening 342 is responsible for transmitting torque, the long screw lift 330 and the short screw lift 340 are formed as one body. The short auger lifts 340 rotate under the force of the long auger lifts 330 and transport the medium ore in the corresponding cavities of the fine screen 430 back to the feed cylinder 120.
At this time, the fine screen 430 contacts the fourth metal contact 114, the coarse screen 420 contacts the first metal contact 111, the fourth metal contact 114 and the first metal contact 111 are simultaneously connected, the hydraulic pump continues to pump a fixed volume of liquid into the fixed hydraulic chamber 230, the liquid in the volume enables the crushing cone 210 to be lifted upwards by one unit, the distance between the crushing mechanism 200 and the crushing cone 210 is reduced, the crushing precision is increased, and the crushing mechanism is used for crushing medium-sized molybdenum ores into small molybdenum ores until the introduced raw materials are completely processed. While the small pieces of ore that have been qualified will fall through the vibrating screen deck fine screen 430 into the lowermost chamber, be rotated by the third spring-pusher plate 443 and finally discharged from the discharge opening 130.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
