[0031] This invention provides a drug crushing and mixing device, such as... Figure 1-6 As shown, the system includes a frame 1, a mixing tank 2 installed on the inner side of the frame 1, a lower guide plate 7 installed on the top of the mixing tank 2 on the inner side of the frame 1, a drive motor 4 extending into the interior of the frame 1 installed at one end of the frame 1, an upper guide plate 3 located above the drive motor 4 installed inside the frame 1, and a transmission mechanism 5 set inside the frame 1 and connected to the output end of the drive motor 4.

[0032] The transmission mechanism 5 includes a first spur gear 501 connected to the output end of the drive motor 4. One end of the first spur gear 501 is connected to a grinding roller 502 extending to the inside of the frame 1. A second spur gear 503 meshes with the outer wall of the first spur gear 501. A push rod 504 is fixedly connected to the outer wall of the second spur gear 503.

[0033] The transmission mechanism 5 also includes a movable rod 505 that is slidably connected inside the frame 1. The movable rod 505 is located above the first spur gear 501. A stop rod 506 is fixedly connected to the bottom end of the movable rod 505. The position of the stop rod 506 is on the same plane as the rotation trajectory of the push rod 504. The outer wall of the movable rod 505 is provided with a protrusion that extends into the interior of the upper guide plate 3.

[0034] The transmission mechanism 5 also includes a second bevel gear 510 rotatably connected to the top of the mixing tank 2. The inner side of the second bevel gear 510 is fixedly connected to the mixing rod 511 via a connecting rod. The inner wall of the frame 1 is fixedly connected to a partition plate 514 located above the grinding roller 502.

[0035] A limiting mechanism 6 is provided at the bottom of the mixing tank 2 and extends into the interior of the mixing tank 2. The limiting mechanism 6 includes a collection tank 601 installed at the bottom of the mixing tank 2 and extending into the interior of the mixing tank 2. A pressing block 602 extending into the interior of the collection tank 601 is provided on the outer wall of the collection tank 601. A connecting rod 603 located inside the collection tank 601 is connected to the top of the pressing block 602. A limiting block 604 extending through the outside of the collection tank 601 and into the inner wall of the mixing tank 2 is fixedly connected to the outer wall of the connecting rod 603.

[0036] There are two upper guide plates 3. One upper guide plate 3 is elastically connected to the frame 1 at the contact position by an elastic block. The outer wall of the lower guide plate 7 is hollow inverted truncated quadrangular shape.

[0037] The transmission mechanism 5 also includes a third spur gear 507 that meshes with the outer wall of the second spur gear 503, a fourth spur gear 508 that meshes with the outer wall of the third spur gear 507, and a first bevel gear 509 that is fixedly connected to one end of the fourth spur gear 508. The first bevel gear 509 meshes with the outer wall of the second bevel gear 510.

[0038] The transmission mechanism 5 also includes a first positioning rod 512 that is sleeved inside the movable rod 505 and extends to the outside of the movable rod 505. The first positioning rod 512 is fixedly connected to the inner side of the frame 1, and a first spring 513 is sleeved on the outer wall of the first positioning rod 512.

[0039] There are two grinding rollers 502, which are respectively connected to one end of the first spur gear 501 and the second spur gear 503.

[0040] In this embodiment, when it is necessary to grind the drug, the prepared drug can be poured into the interior of the frame 1 through the upper feed port. Under the guidance of the upper guide plate 3, the drug will enter between the two grinding rollers 502. By starting the drive motor 4, the drive motor 4 will drive the first spur gear 501 and the second spur gear 503 to rotate. The rotation of the first spur gear 501 and the second spur gear 503 will drive the two grinding rollers 502 to rotate in opposite directions, thereby grinding the drug. During the process, any medicine that bounces around will continue to enter the grinding rollers 502 under the obstruction of the partition 514, and be ground again. The ground medicine will fall into the interior of the mixing tank 2. At the same time, the rotation of the second spur gear 503 will also drive the push rod 504 to rotate synchronously. The rotation of the push rod 504 will give the push rod 506 a thrust, causing the push rod 506 to move to one side under the thrust of the push rod 504. The movement of the push rod 506 will synchronously drive the movable rod 505 to move. The movable rod 505 will move horizontally along the inner wall of the mixing tank 2. As the upper guide plate 3 moves towards the chute, it will also undergo elastic deformation at the position where it contacts the frame 1, adjusting the distance between the ends of the two upper guide plates 3 to decrease until the push rod 504 no longer contacts the abutment rod 506. Then, the abutment rod 506, the movable rod 505, and the upper guide plate 3 will reset under the elastic component of the transmission mechanism 5, and the distance between the two upper guide plates 3 will increase again, achieving the purpose of reducing drug blockage at the ends of the upper guide plates 3. At the same time, the rotation of the second spur gear 503 will also drive the third spur gear 507, the fourth spur gear 508, and the first bevel gear 509. The first bevel gear 509 will transmit power to the second bevel gear 510, causing the second bevel gear 510 to rotate. The stirring rod 511 fixed inside the second bevel gear 510 will also rotate synchronously, stirring and mixing the drug falling into the mixing box 2, achieving the purpose of stirring the drug simultaneously during grinding, further improving the efficiency of grinding and stirring operations.

[0041] In a further preferred embodiment of the present invention, such as Figure 2-6 As shown, the limiting mechanism 6 also includes a second positioning rod 605 fixed to the outer wall of the pressing block 602. The second positioning rod 605 is slidably installed inside the collection box 601, and a second spring 606 is sleeved on the outer wall of the second positioning rod 605.

[0042] In this embodiment, when it is necessary to remove the material after mixing, the user can use their hand to contact the bottom outer wall of the collection box 601. During the contact process, the hand applies a squeezing force to the two pressing blocks 602 on the outer wall of the collection box 601, causing the pressing blocks 602 to drive the connecting rod 603 and the limiting block 604 to move synchronously into the collection box 601 until the end of the limiting block 604 is no longer in the limiting groove inside the mixing box 2. At this time, the user can use their hand to apply a downward pulling force to the collection box 601, causing the collection box 601 to detach from the inside of the mixing box 2, thereby achieving the purpose of removing the mixed medicine.

[0043] In a further preferred embodiment of the present invention, such as Figure 2-6 As shown, one end of the first spur gear 501, the second spur gear 503, the third spur gear 507, and the fourth spur gear 508 is rotatably connected to the inner wall of the frame 1. The interior of the frame 1 is provided with a rotating groove that matches the rotation trajectory of the push rod 504. The outer wall of the push rod 504 is arc-shaped. The inner wall of the frame 1 is provided with a transverse sliding groove that matches the transverse movement trajectory of the movable rod 505. The top of the mixing tank 2 is provided with a positioning groove that matches the rotation trajectory of the second bevel gear 510. The outer wall of an upper guide plate 3 is provided with a movable groove that matches the movement trajectory of the protrusion on the outer wall of the movable rod 505. The outer wall of the partition 514 is L-shaped. The bottom protrusion of the partition 514 is close to but does not contact the outer wall of the grinding roller 502, which is used to block the flying drugs.

[0044] In this embodiment, when the grinding roller 502 is used to grind the drug, the rotation of the grinding roller 502 will synchronously drive the abutment rod 506 and the movable rod 505 to move laterally. During the movement, the movable rod 505 will move along the outer wall of the first positioning rod 12 and be subjected to the squeezing force of the first spring 513, which is an elastic component. When the pushing force on the abutment rod 506 disappears, the movable rod 505 can be reset under the elastic force of the first spring 513.

[0045] In a further preferred embodiment of the present invention, such as Figure 2-6 As shown, the inner wall of the mixing tank 2 is provided with a groove that matches the outer wall of the collection tank 601. The inner wall of the groove is provided with a limiting groove that matches the outer wall of the limiting block 604. The outer wall of the limiting block 604 is in a sloping state.

[0046] In this embodiment, when the collection box 601 needs to be installed, the end of the collection box 601 can be connected to the bottom end of the mixing box 2. The limiting block 604 on the outer wall of the collection box 601 will contact the bottom end of the mixing box 2. The limiting block 604 will enter the interior of the collection box 601 under external force and inclined plane, and be squeezed by the second spring 606 until it contacts the limiting groove inside the mixing box 2. Then the limiting block 604 will pop out under the elastic force of the second spring 606 and enter the limiting groove, so that the limiting block 604 limits the collection box 601. It should be noted that if water needs to be added to mix with the material, water can be poured into the collection box 601 before installing the collection box 601.
