DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-Figure 5 , a crushing device for processing pharmaceutical intermediates, comprising:

[0024] A fixed housing 1 is provided, and a fixed mesh plate 2 is slidably connected between the inner walls of the fixed housing 1. A fixed shaft 5 is rotatably connected to the fixed mesh plate 2. Multiple sets 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, driving the multiple sets of crushing knives 8 to rotate, thereby crushing the pharmaceutical intermediates.

[0025] The drying structure includes a connecting groove 20 provided on the side wall of the fixed housing 1. A fixed outer shell 9 is fixedly connected to the side wall of the fixed housing 1. The fixed outer shell 9 wraps around the connecting groove 20 and is arranged on the inner side. A fan shaft 15 is rotatably connected to the inner wall of the fixed outer shell 9. A heater is fixedly installed inside the connecting groove 20. The heater is an existing device that can heat the air. The fan shaft 15 extends to the inner side of the connecting 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.

[0026] 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;

[0027] The driving structure includes a motor 3 fixedly connected to the lower inner wall of the fixed housing 1, the output end of the motor 3 is fixedly connected to the rotating rod 4, the bottom end of the fixed shaft 5 is provided with a telescopic slot 23, 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, the top end of the rotating rod 4 is fixedly connected to the fixing spring 24, the end of the fixing 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 the upper inner wall of the fixed housing 1 is fixedly connected to an extrusion block 26 corresponding to the extrusion plate 25;

[0028] After the motor 3 is started, its output end drives the rotating rod 4 to rotate, thereby rotating the fixed shaft 5. At the same time, as the fixed shaft 5 rotates, the extrusion plate 25 also rotates. When the extrusion plate 25 rotates to the extrusion block 26, the extrusion block 26 and the extrusion plate 25 squeeze each other, causing the extrusion plate 25 to move downward, and the fixed shaft 5 and the fixed mesh plate 2 also move downward. 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, thereby causing the fixed mesh plate 2 to vibrate up and down, shaking up the intermediate body, so that the crushing knife 8 can crush it, and it is also beneficial for the rolling roller 7 to roll it.

[0029] 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 2 12 corresponding to the bevel gear 11 is fixedly sleeved on the rotating rod 4, and the bevel gear 2 12 is meshed with the bevel gear 11. One end of the connecting shaft 10 passes through the inner wall of the fixed shell 1 and extends to the inner side of the fixed outer shell 9. The end of the connecting shaft 10 located on the inner side of the fixed outer shell 9 is rotatably connected to a rotating wheel 2 18. A rotating wheel 17 corresponding to the rotating wheel 2 18 is fixedly sleeved on the fan shaft 15. The rotating wheel 17 and the rotating wheel 2 18 are connected to each other by a transmission belt 19, and an adjustment structure is provided on the rotating wheel 2 18.

[0030] When the rotating rod 4 rotates, the bevel gear 2 12 fixedly sleeved on the rotating rod 4 rotates accordingly, causing the bevel gear 1 11 meshing with the bevel gear 2 12 to rotate, driving the connecting shaft 10 to rotate. Under the action of the rotating wheel 17, the rotating wheel 2 18 and the transmission belt 19, the fan shaft 15 rotates;

[0031] A damper is fixedly connected to the fixed spring 24, and the fixed spring 24 is fixedly connected to 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.

[0032] The adjustment structure includes a fixed 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 slot 21 and the inner wall of the fixed housing 9 and extends to the outside of the fixed housing 9. The end of the adjustment rod 13 located outside the fixed housing 9 is rotatably connected to the adjustment block 14. A fixed block 22 is fixedly sleeved on the adjustment rod 13, and the fixed block 22 matches the fixed slot 21.

[0033] The adjusting block 14 is moved so that the adjusting rod 13 moves accordingly, and the fixed block 22 is also moved accordingly, so that the fixed block 22 is locked 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 crushed intermediate from being blown too loose and difficult to collect;

[0034] A plurality of fixed rods 6 are fixedly connected to the side wall of the fixed shaft 5, and each fixed rod 6 is rotatably connected to a rolling roller 7 at one end away from the fixed shaft 5, 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 rod 6 will be driven to rotate accordingly, and the rolling roller 7 will rotate accordingly, rolling the intermediates that fall onto the fixed mesh plate 2 and crushing them; a feed port is provided on the upper inner wall of the fixed shell 1, and a discharge port is provided on the side wall of the fixed shell 1 away from the connecting groove 20. The pharmaceutical intermediates enter the fixed shell 1 from the feed port, and the crushed materials are taken out from the discharge port.

[0035] 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 to move the adjusting rod 13 accordingly, driving the fixed card block 22 to move accordingly, so that the fixed card block 22 is stuck in 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, thereby causing the fixed shaft 5 to rotate 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, causing the extrusion plate 25 to move 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 the like to be fixed. 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, and the bevel gear 11 meshing with the bevel gear 2 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, thereby avoiding the crushed intermediate being blown up by the wind, resulting in insufficient crushing.
