A fixed shaft 5 is rotatably connected to the fixed mesh plate 2. A plurality of groups of crushing knives 8 are fixedly connected to the side walls of the fixed shaft 5. A driving structure is installed in the fixed housing 1. The driving structure rotates the fixed shaft 5, and drives the plurality of groups of crushing knives 8 to rotate, thereby crushing the pharmaceutical intermediates. The drying structure includes a connection groove 20 provided on the side wall of the fixed shell 1, a fixed shell 9 is fixedly connected to the side wall of the fixed shell 1, and the fixed shell 9 wraps the connection groove 20 inside. A fan shaft 15 is rotatably connected to the inner wall of the fixed shell 9, and a heater is fixedly installed inside the connection groove 20. The heater is an existing device that can heat the air. The fan shaft 15 extends to the inner side of the connection groove 20, and a plurality of fans 16 are fixedly connected to the side wall of the fan shaft 15. The fan shaft 15 is connected to the driving structure; Under the action of the driving structure, the fan shaft 15 rotates, driving the fan 16 to rotate accordingly, blowing the heated air into the interior of the fixed housing 1 to dry the crushed pharmaceutical intermediates; The driving structure includes a motor 3 fixedly connected to the lower inner wall of the fixed housing 1, a rotating rod 4 fixedly connected to the output end of the motor 3, a telescopic slot 23 is opened at the bottom end of the fixed shaft 5, the rotating rod 4 is extended to the inner side of the telescopic slot 23, and the rotating rod 4 is slidably connected to the inner wall of the telescopic slot 23, a fixed spring 24 is fixedly connected to the top end of the rotating rod 4, one end of the fixed spring 24 away from the rotating rod 4 is fixedly connected to the inner wall of the telescopic slot 23, the top end of the fixed shaft 5 is fixedly connected to the telescopic slot 23, and an extrusion block 26 corresponding to the extrusion plate 25 is fixedly connected to the upper inner wall of the fixed housing 1; After the motor 3 is started, its output end drives the rotating rod 4 to rotate, so that the fixed shaft 5 rotates accordingly. At the same time, as the fixed shaft 5 rotates, the extrusion plate 25 also rotates accordingly. When the extrusion plate 25 rotates to the extrusion block 26, the extrusion block 26 and the extrusion plate 25 squeeze each other, so that the extrusion plate 25 moves downward, the fixed shaft 5 and the fixed mesh plate 2 also move downward, and the fixed spring 24 is deformed. After the extrusion plate 25 and the extrusion block 26 are separated, the elastic force of the fixed spring 24 causes the fixed mesh plate 2 and other structures to move back, so that the fixed mesh plate 2 vibrates up and down, and the intermediate body is shaken up, so that it is convenient for the crushing knife 8 to crush it, and it is also convenient for the rolling roller 7 to roll it; A connecting shaft 10 is rotatably connected to the inner wall of the fixed shell 1, and a bevel gear 11 is fixedly connected to the end face of the connecting shaft 10. A bevel gear 12 corresponding to the bevel gear 11 is fixedly sleeved on the rotating rod 4, and the bevel gear 12 is meshed with the bevel gear 11.

A rotating wheel 17 corresponding to the rotating wheel 18 is fixedly sleeved on the fan shaft 15. The rotating wheel 17 and the rotating wheel 18 are connected to each other through a transmission belt 19, and an adjustment structure is provided on the rotating wheel 18. When the rotating rod 4 rotates, the bevel gear 2 12 fixedly sleeved on the rotating rod 4 rotates accordingly, so that the bevel gear 1 11 meshing with the bevel gear 2 12 rotates, driving the connecting shaft 10 to rotate, and under the action of the rotating wheel 1 17, the rotating wheel 2 18 and the transmission belt 19, the fan shaft 15 rotates; The fixed spring 24 is fixedly connected with a damper, and the fixed spring 24 is fixedly connected with the inner wall of the telescopic slot 23 through the damper to reduce the vibration amplitude of the fixed mesh plate 2. The side wall of the extrusion block 26 and the bottom end of the extrusion block 26 are both rounded to facilitate mutual extrusion between the extrusion block 26 and the extrusion plate 25. The adjustment structure includes a fixed card slot 21 opened on the side wall of the rotating wheel 18, and an adjustment rod 13 is slidably connected to the side wall of the connecting shaft 10. The adjustment rod 13 passes through the fixed card slot 21 and the inner wall of the fixed shell 9 and extends to the outside of the fixed shell 9. The end of the adjustment rod 13 located outside the fixed shell 9 is rotatably connected to the adjustment block 14. A fixed card block 22 is fixedly sleeved on the adjustment rod 13, and the fixed card block 22 matches the fixed card slot 21. The adjusting block 14 is moved to move the adjusting rod 13, and the fixed block 22 is also moved, so that the fixed block 22 is inserted into the fixed slot 21. At this time, the rotation of the connecting shaft 10 can drive the rotating wheel 2 18 to rotate, thereby adjusting the start of the fan 16 to prevent the broken intermediate from being blown too loose and difficult to collect. A plurality of fixed rods 6 are fixedly connected to the side wall of the fixed shaft 5, and an end of each fixed rod 6 away from the fixed shaft 5 is rotatably connected to a rolling roller 7, and the bottom end of each rolling roller 7 is arranged in contact with the top of the fixed mesh plate 2. When the fixed shaft 5 rotates, the fixed rods 6 are driven to rotate accordingly, and the rolling rollers 7 are rotated accordingly to roll and crush the intermediates that fall onto the fixed mesh plate 2; a feed port is opened on the upper inner wall of the fixed shell 1, and a discharge port is opened on the side wall of the fixed shell 1 away from the connecting groove 20, and the pharmaceutical intermediates enter the fixed shell 1 from the feed port, and the crushed materials are taken out from the discharge port.

[0017] In the present invention, when the device is in use, the raw material is first fed into the fixed shell 1, and the adjusting block 14 is moved at the same time to make the adjusting rod 13 move accordingly, driving the fixed card block 22 to move accordingly, so that the fixed card block 22 is clamped into the fixed card slot 21. At this time, the rotation of the connecting shaft 10 can drive the rotating wheel 2 18 to rotate, and then the motor 3 is started. After the motor 3 is started, its output end drives the rotating rod 4 to rotate, so that the fixed shaft 5 rotates accordingly. At the same time, as the fixed shaft 5 rotates, the extrusion plate 25 also rotates accordingly. When the extrusion plate 25 rotates to the extrusion block 26, the extrusion block 26 and the extrusion plate 25 squeeze each other, so that the extrusion plate 25 moves downward, the fixed shaft 5 and the fixed mesh plate 2 also move downward, and the fixed spring 24 is deformed. After the extrusion plate 25 and the extrusion block 26 are separated, the elastic force of the fixed spring 24 causes the fixed mesh plate 2 to rotate. The structure moves back, so that the fixed mesh plate 2 vibrates up and down, and the intermediate is shaken up, so that the crushing knife 8 can crush it, and it is also beneficial for the rolling roller 7 to roll it. Moreover, when the rotating rod 4 rotates, the bevel gear 2 12 fixedly sleeved on the rotating rod 4 rotates accordingly, so that the bevel gear 11 meshing with the bevel gear 12 rotates, driving the connecting shaft 10 to rotate. Under the action of the rotating wheel 17, the rotating wheel 2 and the transmission belt 19, the fan shaft 15 rotates, thereby driving the fan 16 to rotate accordingly, blowing the heated air into the inside of the fixed shell 1 to dry the crushed pharmaceutical intermediate. After drying in the intermediate, the adjusting block 14 is adjusted to separate the fixed card block 22 from the fixed card slot 21, so that the fan 16 no longer rotates, so as to avoid the crushed intermediate being blown up by the wind, resulting in insufficient crushing.
