Control structure for adjusting distance between sieve plate and hammer head of stone crusher

The utility model relates to the technical field of stone crushers, and discloses a control structure for adjusting the distance between a sieve plate and a hammer head of a stone crusher. The control structure for adjusting the distance between the sieve plate and the hammer head of the stone crusher comprises a shell, a bearing is installed in the center of the shell in a penetrating mode, a driving shaft is installed in the bearing in a penetrating mode, the hammer head is fixedly installed on the outer side of the driving shaft, and a driving motor is installed at the left end of the driving shaft in a penetrating mode. Due to the fact that the tungsten steel alloy has high hardness, the abrasion degree generated when the hammer head and the sieve plate collide with stone can be reduced, due to the fact that the hammer head and the sieve plate are made of 5160 steel, the 5160 steel has good hardness and good toughness and can absorb part of stress generated during collision, and the impact strength of the
