The invention has the beneficial effects that:

(1) the ore screening device provided by the invention has the advantages that through the arrangement of the feeding structure, the ore to be screened can be automatically fed through the reciprocating motion of the feeding structure, so that the ore screening efficiency is improved, namely, the lifting platform is matched with the enclosing plate for loading the ore to be screened, as the lifting platform is fixedly connected with the round rod and the movable rod which are respectively connected in the first sliding chute and the second sliding chute in a sliding manner, the lifting platform can reciprocate up and down together with the round rod and the movable rod, and the top end part of the first sliding chute becomes bent, when the movable rod slides to the top end position of the second sliding chute, the movable rod is changed from sliding motion to rotating motion, meanwhile, the round rod can continuously slide in the first sliding chute, so that the whole lifting platform rotates by taking the movable rod as a shaft, and the lifting platform gradually becomes inclined in the rotating process, the ores poured into the lifting platform and the enclosing plate can be poured out of the lifting platform along with the inclination of the lifting platform, and the reciprocating motion of the lifting platform can be automatically carried out, so that an operator only needs to put the ores to be screened onto the lifting platform when the lifting platform descends every time, the operation is simple and convenient, the manual workload is reduced, and the working efficiency is improved; through bearing structure's setting, make the pay-off structure be higher than ground at the in-process of motion all the time, structural pouring of pay-off is followed to the ore, just can utilize the gravity of ore self and whereabouts, make the ore take place to roll, thereby improve the screening effect, because the setting of first bracing piece and second bracing piece promptly, make the elevating platform have the position motion of take the altitude apart from ground all the time, then when the elevating platform inclines, the ore poured out from the elevating platform can utilize self gravity and fall and roll, thereby improve the screening effect, and first bracing piece and second bracing piece play fixed elevating platform and guide the effect of elevating platform with the motion of specific orbit.

(2) The ore screening device of the invention enables the feeding structure to reciprocate through the arrangement of the driving structure, thereby enabling ores loaded on the feeding structure to finish lifting, namely, as the output shaft of the motor is fixedly connected with the first screw rod which is in threaded connection with the connecting block, the connecting block is connected with the two connecting plates which are in rotary connection with the sliding seat and are in rotary connection with the rotating shaft, and the sliding seat is in sliding connection with the bottom of the lifting plate, when the output shaft of the motor rotates, the first screw rod can be driven to rotate, as the sliding seat can only slide, the connecting block can only spirally move on the first screw rod, therefore, when the motor rotates in different directions to drive the first screw rod to rotate in different directions, the connecting block can only vertically move along with the rotation of the first screw rod, and further drives the rotating shaft to vertically move, the rotating shaft can drive the sliding seat to move up and down by moving up and down, so that the lifting table can complete lifting and descending, and when the lifting table inclines, the sliding seat can rotate relative to the connecting plate and slide relatively at the bottom of the lifting table, but cannot be separated from the lifting table.

(3) The ore screening device can automatically screen ores falling from a feeding structure through the arrangement of the screening structure, namely, because the plate frame is obliquely arranged, and a plurality of slide bars are arranged in the plate frame at equal intervals, when the lifting platform rises to incline, the ores in the lifting platform and the enclosing plate can gradually roll down to the plate frame, the ores can be screened according to the intervals of the slide bars in the process of rolling down, as long as the lengths of the plate frame and the slide bars are proper, the ores with small volume and enough volume to pass through the gaps of the slide bars can be screened out and fall into the containing box through the blanking holes before the ores roll down to the bottom of the plate frame, and the ores with relatively large volume can finally roll down to the tail end of the plate frame for further processing, in the process, the screening of the ores mainly utilizes the gravity of the ores to roll on the plate frame, thereby solved the relative quality of ore great and inconvenient problem of rocking the screening of going on.

(4) The ore screening device can be matched and adjusted to screen ores with different sizes according to needs by controlling the arrangement of the structure, namely, as the inner wall of the plate frame is connected with the telescopic rod, each node of the telescopic rod is connected with the connecting rod, and the connecting rods are respectively connected with the slide rods in the through holes, the connecting rods can move along with the telescopic rod when the telescopic rod is telescopic and drive the slide rods to slide together, and because of the telescopic characteristic of the telescopic rod, the slide rods always keep equal intervals when moving along with the telescopic rod, so that when the telescopic rod is telescopic, the intervals and the intervals are increased, ores with relatively large volume can be screened into the containing box, when the intervals of the slide rods are reduced, only ores with relatively small volume can be screened into the containing box, and because still sliding connection has the slide on the inner wall of sheet frame, and the one end of slide is connected with the telescopic link, therefore the slide bar slides and just can drive the telescopic link flexible, and because the one end that deviates from the telescopic link of slide rotates and is connected with the second screw rod, and the lateral wall threaded connection of second screw rod and sheet frame, and fixedly connected with carousel on the second screw rod, therefore when making the carousel rotate for the manual manipulation carousel, just can drive the second screw rod and rotate, the second screw rod rotates and just can drive the slide and slide, and then the flexible of control telescopic link, and adjust the interval of a plurality of slide bars, and because the second screw rod has the auto-lock effect, consequently the slide bar can not take place to rock because of the roll of ore, can not change the interval easily in the.
