[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0016] As shown in Figures 1-2 a kind of drug crusher with coarse and fine adjustment device, including rotationally arranged between two bearing seats crushing main shaft 1, in combination Figure 1 As shown, the through hole 2 is formed in the crushing main shaft 1 along the axis, the threaded screw rod 4 is rotationally arranged in the through hole 2, further, in combination Figure 2As shown, the outer side of the threaded screw rod 4 is sleeved with a ball plane bearing 3 close to one end of the crushing main shaft 1, the ball plane bearing 3 is embedded in the through hole 2, the end of the crushing main shaft 1 is detachably provided with a fastening sleeve 5 for limiting the ball plane bearing 3, the inner side of the fastening sleeve 5 is embedded with a thrust bearing 6 sleeved on the outer side of the threaded screw rod 4, it should be noted that the thickness of the thrust bearing 6 is greater than the thickness of the fastening sleeve 5, the outer side of the threaded screw rod 4 is fixedly provided with a grinding disc adjusting handle 7 on one side of the fastening sleeve 5, the side wall of the grinding disc adjusting handle 7 cooperates with one side of the thrust bearing 6, preferably, the setting of the thrust bearing 6 prevents the grinding disc adjusting handle 7 from rubbing with the fastening sleeve 5 when rotating.
[0017] Specifically in this embodiment, in combination with Figure 1 As shown, the outer side of the threaded screw rod 4 is matched with a sliding block 8 sliding in the through hole 2, the outer wall of the crushing main shaft 1 is symmetrically provided with a straight slot hole 9 communicating with the through hole 2, it should be noted that the straight slot hole 9 is perpendicular to the direction of the through hole 2, the outer side of the crushing main shaft 1 is transversely and slidingly provided with a grinding adjusting disc 10, a plurality of crushing blades 12 are detachably provided on the grinding adjusting disc 10, the grinding adjusting disc 10 is provided with a fastening bolt 11 penetrating through the straight slot hole 9 and cooperating with the sliding block 8.
[0018] Preferably, the threaded screw rod 4 is driven to rotate by the grinding disc adjusting handle 7, the threaded screw rod 4 cooperates with the sliding block 8 when rotating and drives the grinding adjusting disc 10 and the crushing blades 12 to move left and right on the crushing main shaft 1, avoiding the problem that the existing adjustment of the left and right positions of the crushing blades 12 on the crushing main shaft 1 needs to be operated after the shell is disassembled, and the operation is simple; at the same time, it avoids the pollution of the medicine by external adjusting accessories when adjusting the left and right positions of the crushing blades 12.
