DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example: Figure 1-7 As shown, the utility model provides a biomedical processing device, including a support plate 1, a box body 2 is fixedly installed on the top of the support plate 1, a U-shaped fixed block 21 is fixedly installed on the top of the box body 2, a first rotating shaft 22 is rotatably installed in the middle of the U-shaped fixed block 21, a first gear ring 24 is fixedly installed on the outside of the first rotating shaft 22 through a first supporting leg, a first gear 25 is meshed and connected to the inner side of the first gear ring 24, a second gear 26 is rotatably sleeved on the first rotating shaft 22 and is located below the first gear ring 24, a second gear 251 is meshed and connected to the inner side of the second gear ring 26 and the outer side of the first gear 25, a hollow cylinder 27 is fixedly installed on the bottom end of the second gear ring 26 through a second supporting leg, a plurality of crushing knives 28 that are offset from each other are fixedly installed on the outside of the hollow cylinder 27 and the first rotating shaft 22, a guide plate 20 is rotatably connected to the inside of the box body 2 through a rotating shaft, and a circular filter screen 201 is fixedly installed in the middle of the guide plate 20.
[0023] By adopting the above technical solution, when the first rotating shaft 22 rotates, the several crushing knives 28 on the first rotating shaft 22 are driven to rotate, and at the same time, the first gear ring 24 is driven to rotate, the meshing between the first gear ring 24 and the first gear 25 drives the first gear 25 to rotate, and the meshing between the first gear 25 and the second gear 251 drives the second gear 251 to rotate in the same direction as the first gear ring 24. As the second gear 251 rotates, the meshing with the second gear ring 26 drives the second gear ring 26 to rotate in the opposite direction to the first gear ring 24. As the second gear ring 26 rotates in the opposite direction, the several crushing knives 28 on the hollow cylinder 27 are driven to rotate in the opposite direction. As the first rotating shaft 22 and the hollow cylinder 27 rotate in the opposite directions, the large volume of pharmaceutical raw materials in the box 2 can be crushed more fully, which is convenient for later grinding.
[0024] A lifting bin 11 is fixedly installed on one side of the box body 2, and a spiral conveying roller 12 is rotatably installed inside the lifting bin 11. A second rotating shaft 4 is rotatably penetrated on one side of the box body 2 away from the lifting bin 11, and three evenly distributed strip blocks 41 are fixedly installed on one side of the second rotating shaft 4. A square block 42 is movably installed outside the strip block 41, and a rectangular groove 421 is penetrated in the middle of the square block 42, and a fan-shaped groove 422 is penetrated at the diagonal of the rectangular groove 421 and located inside the square block 42. Guide rods 43 are fixedly installed on both sides of the square block 42, and the top of the guide rod 43 is hinged to one side of the bottom end of the guide plate 20, and the external sliding sleeve of the guide rod 43 is provided with a fixed seat 44, and one side of the fixed seat 44 is fixedly installed on the inner wall of the box body 2, and a second motor 45 is fixedly installed on the side of the second rotating shaft 4 away from the square block 42 and located outside the box body 2.
[0025] By adopting the above technical scheme, when the second rotating shaft 4 rotates, it drives the bar block 41 to rotate. With the rotation of the bar block 41, the contact between the bar block 41 and the square block 42 drives the guide rod 43 on the square block 42 to move up and down reciprocatingly in the fixed seat 44. The hinge between the guide plate 20 and the second rotating shaft 4 drives the guide plate 20 to shake. There is a rubber pad between the inner side of the box 2 and the guide plate 20 on the guide rod 43 to prevent large particles from falling when the guide plate 20 shakes and to seal the guide plate 20 and the box 2, so that the fully crushed pharmaceutical raw materials in the box 2 are filtered out from the circular filter screen 201, and the incompletely crushed pharmaceutical raw materials enter the lifting bin 11, and then are transported to the box 2 through the spiral conveying roller 12 for re-crushing, thereby improving the quality of the crushing of the pharmaceutical raw materials, making the pharmaceutical raw materials crushed more fully, and at the same time, shaking is used to prevent the incompletely crushed pharmaceutical raw materials from clogging the circular filter screen 201.
[0026] A corresponding discharge port 202 and a first return material inlet 13 are provided on opposite sides of the box body 2 and the lifting bin 11 and at the position of the guide plate 20 , and a corresponding second return material inlet 203 and a return material outlet 14 are provided above the discharge port 202 and the first return material inlet 13 .
[0027] By adopting the above technical solution, when there is insufficiently crushed pharmaceutical raw material, it enters the lifting bin 11 from the discharge port 202 and the first return material inlet 13, and then is transported by the spiral conveyor roller 12, and enters the box 2 again from the return material outlet 14 and the second return material inlet 203 for re-crushing, thereby improving the completeness of the crushing of the pharmaceutical raw material.
[0028] The hollow cylinder 27 is rotatably inserted in the box body 2 , and the length of the hollow cylinder 27 is smaller than the length of the first rotating shaft 22 .
[0029] The first rotating shaft 22 rotates and penetrates the hollow cylinder 27 . A first motor 222 is fixedly mounted on the top of the first rotating shaft 22 and located on the top of the U-shaped fixing block 21 .
[0030] By adopting the above technical solution, when the first motor 222 is started, the first rotating shaft 22 is driven to rotate, thereby driving the first gear ring 24 to rotate.
[0031] Two sets of symmetrically distributed fixing plates 3 are fixedly installed on the inner side of the U-shaped fixing block 21 , and the first gear ring 24 and the second gear ring 26 are respectively rotatably engaged in the corresponding fixing plates 3 .
[0032] By adopting the above technical solution, the first gear ring 24 and the second gear ring 26 are supported to prevent them from falling when they rotate.
[0033] A first rotating rod 29 is rotatably mounted in the middle of the first gear 25, and a first fixed block 31 is rotatably sleeved on the bottom of the first rotating rod 29. A second rotating rod 291 is rotatably mounted in the middle of the second gear 251, and a second fixed block 32 is rotatably sleeved on the top of the second rotating rod 291. The second fixed block 32 and one side of the first fixed block 31 are both fixedly mounted on the inner side of the U-shaped fixed block 21.
[0034] By adopting the above technical solution, by setting the second fixing block 32 and the first fixing block 31, the first gear 25 and the second gear 251 and the corresponding first rotating rod 29 and the second rotating rod 291 are supported to prevent the first gear 25 and the second gear 251 from falling when rotating.
[0035] A grinding chamber 5 is fixedly installed inside the box body 2 and below the circular filter screen 201. The grinding chamber 5 is fixedly passed through the support plate 1. A third rotating shaft 51 rotates and passes through the inner wall of the grinding chamber 5. A grinding stone 52 is fixedly installed outside the third rotating shaft 51. The diameter of the grinding stone 52 is smaller than the diameter of the grinding chamber 5, and the outer side of the grinding stone 52 does not contact the inner side of the grinding chamber 5. A third motor 53 is fixedly installed at the bottom of the third rotating shaft 51 and located at the bottom of the grinding chamber 5.
[0036] By adopting the above technical solution, when the third rotating shaft 51 rotates, it drives the grinding stone 52 to rotate, and the grinding stone 52 and the grinding chamber 5 directly cooperate to grind the sufficiently crushed pharmaceutical raw materials into powder more fully.
[0037] Working principle: In specific operation, the first motor 222, the second motor 45 and the third motor 53 are turned on at the same time, and then a large volume of pharmaceutical raw materials are put into the box body 2 from the feed port at the top of the box body 2. The first motor 222 drives the first rotating shaft 22 to rotate, and at the same time, drives a plurality of crushing knives 28 on the first rotating shaft 22 to rotate and drives the first gear ring 24 to rotate. The meshing between the first gear ring 24 and the first gear 25 drives the first gear 25 to rotate. The meshing between the first gear 25 and the second gear 251 drives the second gear 251 to rotate in the same direction as the first gear ring 24. With the rotation of the second gear 251, the meshing between the second gear ring 26 drives the second gear ring 26 to rotate in the opposite direction to the first gear ring 24. With the reverse rotation of the second gear ring 26, the plurality of crushing knives 28 on the hollow cylinder 27 are driven to rotate in the opposite direction. With the opposite rotation between the first rotating shaft 22 and the hollow cylinder 27, the large volume of pharmaceutical raw materials in the box body 2 are crushed.
[0038] Then, the second motor 45 drives the second rotating shaft 4, and then drives the bar block 41 to rotate. As the bar block 41 rotates, one end of the bar block 41 contacts one side of the inner wall of the rectangular groove 421. At the same time, the other two bar blocks 41 contact the fan-shaped groove 422, driving the square block 42 to move. When one end of the bar block 41 contacts the other side of the inner wall of the rectangular groove 421, the square block 42 is driven to move in the opposite direction, thereby driving the square block 42 and the guide rod 43 to reciprocate up and down in the fixed seat 44. The hinge between the guide plate 20 and the second rotating shaft 4 drives the guide plate 20 to shake, so that the pharmaceutical raw materials in the box 2 are fully crushed. The raw materials are filtered from the circular filter screen 201 into the grinding bin 5, and then the third motor 53 drives the third rotating shaft 51 to rotate, and then drives the grinding stone 52 to rotate, so that the fully crushed raw materials are ground into powder, and the ground raw materials fall directly from the grinding bin 5, and the incompletely crushed raw materials enter the lifting bin 11, and then through the cooperation of the first rotating shaft 22 and the pulley and the transmission belt at the top of the spiral conveying roller 12, the first motor 222 drives the spiral conveying roller 12 to rotate at the same time, and then the incompletely crushed raw materials are conveyed to the box body 2 for re-crushing, so that the raw materials are crushed more fully.
