first cross axle (31) and second cross axle (34) and left end all extend to the outside of receiving workbin (28) and respectively fixedly connected with first drive wheel (33) and second drive wheel (36), meshing has drive wheel (37) between first drive wheel (33) and second drive wheel (36), the center department fixed mounting of drive wheel (37) has transmission shaft (38), driven round (39) have set firmly on transmission shaft (38).

9. The rod mill sand making machine with adjustable discharging fineness of claim 8, characterized in that: the driving mechanism comprises a rotary wheel (40), a power wheel (41), a speed reducer (42) and a driving motor (43), the rotary wheel (40) is fixedly installed on the outer wall of the barrel body (1), the power wheel (41) is meshed with the outer wall of the rotary wheel (40), a power shaft is fixedly installed in the center of the power wheel (41), and the left end of the power shaft is connected with an output shaft of the driving motor (43) through the speed reducer (42);

and a driving wheel (44) is fixedly arranged at the right end of the power shaft, and the driving wheel (44) is connected with a driven wheel (39) through a synchronous belt (45).

10. The use method of the rod mill sand making machine with the adjustable discharging fineness is characterized by comprising the following steps of:

s1, materials are continuously filled into the barrel body (1), the barrel body (1) is driven to rotate by the driving motor (43), and when the barrel body (1) rotates, a grinding body steel rod in the barrel body rises to a certain height under the action of friction and centrifugal force and is thrown down, so that the materials are impacted, ground and crushed;

s2, the ground and crushed materials enter the fixing frame (5) through the discharge hole (4) and the adjusting hole (12) under the action of overflow and continuous feeding, the materials meeting the size requirement are discharged into the material receiving cover (8) through the annular filter screen (6) and discharged through the discharging pipe (9), and the materials not meeting the size requirement return to the barrel body (1) through the adjusting hole (12) and the discharge hole (4);

s3, pushing the push ring (23) to enable the adjusting plate (11) to move left and right in the movable groove (10) so as to control the size of the overlapped area of the adjusting hole (12) and the discharging hole (4) and further control the discharging fineness.
