A connecting rod 231 is rotatably arranged between the top plate 24 and the first sliding block 23 (i.e., the top end of the connecting rod 231 is rotatably connected to the top plate 24, and the bottom end of the connecting rod 231 is rotatably connected to the first sliding block 23). When the first rotating shaft 22 rotates, the two first sliding blocks 23 move synchronously and reversely under the action of the first circulation grooves and the first guide columns. The top plate 24 can be driven to move up and down reciprocatingly under the action of the connecting rod 231. A plurality of top columns 241 matched with the screen holes are arranged on the top surface of the top plate 24. A third rotating shaft 25 is arranged below the first rotating shaft 22. The two ends of the third rotating shaft 25 are rotatably connected to the end plates 221. A driving gear 251 is arranged at each end of the third rotating shaft 25. A driven gear 222 matched with the driving gear 251 is arranged at each end of the first rotating shaft 22. The diameter of the driving gear 251 is much larger than the diameter of the driven gear 222. The number of teeth on the driving gear 251 is the same as the number of teeth on the driven gear 222, so that the first rotating shaft 22 rotates one revolution each time the driving gear 251 is matched with the driven gear 222. A rack 252 matched with the driving gear 251 is arranged on the side wall of the screening box 21 below the driving gear 251. The top plate 24 can move horizontally in the screening box 21 by a distance each time the driving gear 251 is matched with the rack 252. The moving distance of the top plate 24 is the same as the distance between the two screen holes in the moving direction of the top plate 24.

[0025] Referring to Figures 1-5The top surface of the screening box 21 is provided with two opposite side plates 211, which are respectively arranged at the two sides of the top surface of the screening box 21, and the two ends of the side plate 211 extend to the direction of the conveying belt 1.

The end of the connecting plate 271 away from the cross rod group 262 is slidably connected with a push plate 27, and the push plate 27 can reciprocally slide relative to the connecting plate 271. The side wall of the side plate 211 is provided with a guide groove 212 matched with the push plate 27, and the two ends of the push plate 27 are provided with a third guide column matched with the guide groove 212. The guide groove 212 includes a top groove and a bottom groove, and the two ends of the top groove and the bottom groove are connected through an inclined groove. When the third guide column is in the bottom groove, the bottom end of the push plate 27 abuts against the top surface of the screening box 21, at this time, the push plate 27 moves from one conveying belt 1 to the direction of the other conveying belt 1, and can push the ore through the screening box 21; when the third guide column is in the top groove, the push plate 27 can be reset to avoid interference with the ore on the conveying belt 1.

[0026] Referring to Figures 1-5 The bottom side of the screening box 21 is provided with a mounting plate, and the mounting plate is rotatably provided with a guide shaft 28. The shaft center of the guide shaft 28 and the shaft center of the third rotating shaft 25 are located on the same horizontal plane. The end of the third rotating shaft 25 close to the guide shaft 28 penetrates out of the screening box 21. The end of the second rotating shaft 26 close to the guide shaft 28 penetrates through the side plate 211. The side plate 211 close to the guide shaft 28 is provided with a driving element 29, and the output shaft of the driving element 29 penetrates through the side plate 211. The second rotating shaft 26, the guide shaft 28 and the output shaft of the driving element 29 are provided with transmission gears matched with the chain.

[0027] Referring to Figures 1-5 Preferably, a plurality of first limiting rods penetrating through the first sliding block 23 are arranged beside the first rotating shaft 22, and a plurality of second limiting rods penetrating through the second sliding block 261 are arranged beside the second rotating shaft 26, so as to improve the smoothness of the operation of the device.

[0028] Referring to Figures 1-5 Preferably, the driving element 29 is a rotary motor, which can provide sufficient power for the operation of the device.

[0029] In the implementation of the present application: the ore moves from the conveying belt 1 close to the second rotating shaft 26 to the conveying belt 1 away from the second rotating shaft 26, when the driving member 29 is started, the driving member 29 drives the chain to run, at this time, under the cooperation of the transmission gear on the second rotating shaft 26 and the chain, the second rotating shaft 26 rotates, under the action of the second circulating groove, the two second sliding blocks 261 reciprocate in the opposite direction, thereby driving the push plate 27 to reciprocate along the side plate 211, when the push plate 27 moves away from the second rotating shaft 26, the third guide column is in the bottom groove, the push plate 27 pushes the ore through the screening box 21, wherein the ore with a smaller diameter falls on the conveying belt below the screening box 21 after passing through the sieve hole, and the ore with a larger diameter is pushed onto the conveying belt 1 away from the second rotating shaft 26; when the push plate 27 moves towards the second rotating shaft 26, the third guide column is in the top groove, and the push plate 27 is not in contact with the ore on the conveying belt 1. At the same time, under the cooperation of the transmission gear on the third rotating shaft 25 and the chain, the third rotating shaft 25 rotates, when the driving gear 251 cooperates with the driven gear 222 once, it can drive the first rotating shaft 22 to rotate one revolution, so that the top plate 24 reciprocates once, and when the top column 241 rises, it can lift the ore stuck in the sieve hole; when the driving gear 251 cooperates with the rack 252 once, it can make the top plate 24 move horizontally in the screening box 21 for a distance, when the top plate 24 moves to the other end of the screening box 21, the driving member 29 reverses (there are various ways to control the running direction of the driving member 29, for example, a distance sensing element is added to the side plate 211, and the rotation direction of the driving member 29 is controlled by sensing the distance between the side plate 211 and the side wall of the screening box 21), the user can adjust the length of the screening box 21 and the diameters of the transmission gear, the driving gear 251 and the driven gear 222 to ensure that the push plate 27 is located at the initial position (i.e. close to the second rotating shaft 26) when the driving member 29 changes the running direction each time.

[0030] The present application provides a mine transfer conveying device, by setting the screening assembly, which can automatically push the ore, avoid the ore accumulation on the conveying belt and the top surface of the screening box, improve the screening efficiency, and can clean the sieve hole, avoid the ore blockage in the sieve hole, ensure good screening effect, and the pushing of the ore and the cleaning of the sieve hole in the present application can be driven by one driving member, which reduces the manufacturing and use cost, and is convenient for promotion.
