The rare earth ore crusher according to claim 6, characterized in that a longitudinal guide rod (63) positioned below the charging barrel (201) is fixed in the lower box body (2), the guide rod (63) movably penetrates through the corresponding fixed slide block (62), a longitudinal sliding groove is arranged on the side surface of the lower box body (2), and the fixed slide block (62) is in sliding fit in the corresponding sliding groove;
the longitudinal length of the sliding groove is smaller than that of the movable plate (64) and larger than the longitudinal width of the fixed sliding block (62), and the movable plate (64) always covers the sliding groove in the moving process.
10. The crushing method of the rare earth ore crusher is characterized by comprising the following steps:
step 1, controlling a driving motor (43) to work through an operation controller (8), driving the driving motor (43) to work to drive a rotating shaft (41) to rotate, then pouring rare earth ore to be crushed into an upper box body (3), at the moment, performing first re-crushing on the rare earth ore by two rotating crushing rollers (42), and enabling the ore after the first re-crushing to fall into a charging barrel (201) through a gathering hopper (203);
step 2, when the rotating shaft (41) rotates, the arranged rotating disc (72) rotates to drive the driving pin (73) to rotate, the driving pin (73) rotates to drive the rectangular frame (74) to move up and down periodically, the rectangular frame (74) moving up and down periodically drives the second fixing rod (76) and the connecting plate (57) to move transversely through the inclined rod (75), and when the two connecting plates (57) are close to each other, the arranged two cylindrical rods (53) are close to each other and drive the two circular crushing plates (52) to close to each other to perform secondary crushing on ore in the charging barrel (201);
step 3, when the two cylindrical rods (53) are close to each other, when the fixing pin (55) slides into the chute from the straight groove of the guide groove (54), the fixed fixing pin (55) can enable the cylindrical rods (53) which move transversely to rotate for a certain angle, the directions of the two chutes are opposite, the directions of the two cylindrical rods (53) when rotating are opposite, at the moment, the rotating directions of the two circular crushing plates (52) are opposite, and then the ore is twisted, so that the ore is further crushed;
step 4, when the connecting plate (57) transversely moves, the arranged first fixing rod (65) and the roller (66) can transversely move, the roller (66) slides in the wave-shaped groove, and when the roller transversely moves, the movable plate (64) can be driven to longitudinally shake, so that the fixed sliding block (62) and the screening box (61) are driven to longitudinally shake, the ore falling from the screening net plate (202) is screened, and the screened ore falls from the bottom of the lower box body (2).
