All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] As attached Figure 1 As shown, a coal gangue continuous separation device includes a flat-angle belt conveyor 1, a feeding device 2, an identification device 3, a coal gangue separation device 4, and a gangue collecting trough 5; the flat-angle belt conveyor 1 is connected to the feeding device 2, the feeding device 2 is connected to the identification device 3, the identification device 3 is connected to the coal gangue separation device 4, there are two coal gangue separation devices 4, which are respectively arranged on the left and right sides of the flat-angle belt conveyor 1, and a gangue collecting trough 5 is provided at the lower end of the coal gangue separation device 4.

[0025] As attached Figure 2 、 3 As shown, the coal gangue separation device 4 includes an impeller 1 6, an impeller 2 7, a driving device 8, and an electrode conversion axis 9. The impeller 1 6 is arranged on the left side of the impeller 2 7. The impeller 1 6 and the impeller 2 7 are connected by the electrode conversion axis 9. The electrode conversion axis 9 is arranged at the center of the impeller 1 6 and the impeller 2 7. The width of the impeller 1 6 and the impeller 2 7 is 50 mm, and the middle interval between the impeller 1 and the impeller 2 is 50 mm. The driving device 8 is respectively provided on both sides of the impeller 1 6 and the impeller 2 7. The impeller 1 6 and the impeller 2 7 are both composed of an impeller skeleton 10 and a wear-resistant rubber plate 11. The contact surface of the impeller skeleton 10 is provided with a wear-resistant rubber plate 11. The impeller skeleton 10 is made of high-strength steel. The impeller 1 6 and the impeller 2 7 are both provided with energy storage blocks 12 and electromagnetic poles 13. The electromagnetic poles 13 are provided at both ends of the impeller 1 6 and the impeller 2 7.

[0026] As attached Figure 4 As shown, energy storage blocks 12 are provided in impeller 1 6 and impeller 2 7 to ensure that sufficient impulse is provided at the moment of contact with the gangue. When the impeller is in the initial position, positive and negative poles of the power supply are provided on both sides of the electrode conversion axis. The positive pole of the power supply is connected through wiring one, and the negative pole of the power supply is connected through wiring two, so that the A and B ends of the impeller form electromagnetic two-pole terminals, and stop at the A end of the impeller under the action of magnetic force; when the impeller rotates through the striking position, wiring one and wiring two switch the positive and negative poles of the power supply through the electrode conversion axis, causing the A and B electrodes of the impeller to switch, and then the energy storage block 12 runs from the A end to the B end under the action of the magnetic force, recovers the initial position, and completes a striking action.

[0027] Working principle: The raw coal entering the flat-angle belt conveyor 1 is arranged into two rows by the distribution device 2, and the gangue, its size and position are identified by the identification device 3. Then, through system calculation, an instruction is sent to the coal-gangue separation device after the gangue enters the specified range. When the gangue is less than 100mm, the driving device 8 drives the impeller 1 6 to rotate alone; when the gangue is larger than 100mm, the driving device drives the impeller 1 6 and the impeller 2 7 to rotate at the same time, rotating to hit the gangue and make it fall into the gangue collecting trough 5.
