Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical grinding and relates to a novel grinding device. Background Technology

[0002] When grinding medicines such as ENT drugs, medical staff currently mostly use a grinding rod to strike and grind them inside the grinding jar. This grinding method requires manual operation by medical staff, especially when there are many patients. The grinding time is long, the labor intensity is high, and the grinding efficiency is poor.

[0003] Therefore, this utility model provides a novel grinding device to solve the above problems. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a novel grinding device. The technical solution adopted is as follows: It includes a frame, the frame including a base, a vertical arm fixedly connected to the right end of the base, a horizontal plate fixedly connected to the left side of the upper end of the vertical arm, and rotating shaft fixing arms fixedly connected to the left and right sides of the lower sidewall of the vertical arm, respectively. A conical storage hopper is rotatably inserted into the left opening of the base. First teeth are evenly formed on the outer circumferential wall of the upper opening of the conical storage hopper. A hammer grinding mechanism is suspended inside the conical storage hopper. The hammer grinding mechanism includes a conical... The grinding bucket has its inner sidewalls at the upper opening fixedly connected to the front and rear sides of the lower end of a movable plate. Rectangular through slots are formed on the left and right sidewalls of the upper part of the movable plate. Sliding shafts are fixedly connected to the front and rear ends of the upper part of the movable plate, respectively. The front and rear sliding shafts pass through the left end of the horizontal plate. Springs are fitted onto the upper ends of the sliding shafts, and nuts are threaded onto the sliding shafts above the springs. A transmission mechanism is rotatably mounted within the rectangular through slots. The right end of the transmission mechanism meshes with a drive mechanism. The drive mechanism is installed between the base and the horizontal plate.

[0005] As a preferred embodiment of this utility model, the taper and bottom of the conical grinding hopper match the taper and bottom of the conical storage hopper; this design ensures that the conical grinding hopper completely fits the interior of the conical storage hopper when it moves downward, thereby ensuring that the medicine between the two is fully squeezed and ground, improving the grinding effect.

[0006] In a preferred embodiment of this utility model, the transmission mechanism includes an eccentric wheel, which is movably inserted into the rectangular through slot. The eccentric wheel is fixedly mounted on the left end of a horizontal shaft. The horizontal shaft is sequentially rotatably inserted into the lower ends of the left and right rotating shaft fixing arms. A first bevel gear is fixedly mounted on the right end of the horizontal shaft. By employing a transmission mechanism, the power of the drive mechanism can be transmitted to the eccentric wheel, thereby driving the moving plate to move up and down, and causing the conical grinding bucket to move up and down to hammer the medicine.

[0007] As a preferred embodiment of this utility model, the upright arm is fixedly installed with reinforcing ribs at the front and rear side walls of the connection between the upright arm and the base and the horizontal plate, and a U-shaped handle is also provided on the right side wall of the upright arm.

[0008] In a preferred embodiment of this utility model, the driving mechanism includes a vertical shaft, the upper end of which is rotatably inserted into the right end of the horizontal plate. A second bevel gear and a driving gear are sequentially fixedly mounted on the vertical shaft from top to bottom. The driving gear meshes with the first bevel gear. The lower end of the vertical shaft is fixedly connected to the output shaft of a motor, and the motor is fixedly mounted on the base. By using a single motor to drive the conical storage hopper to rotate, the hammer grinding mechanism moves up and down to cooperate with the conical storage hopper, grinding and pulverizing the internal medicine, thereby improving grinding efficiency.

[0009] The beneficial effects of this utility model are as follows: The vertical shaft is driven to rotate by a motor, which in turn drives the drive gear and the second conical gear to rotate. The drive gear drives the conical storage hopper to rotate, and the second conical gear drives the eccentric wheel to rotate through a horizontal transmission mechanism, thereby driving the moving plate to move up and down, which in turn drives the lower conical grinding hopper to move up and down. This achieves the simultaneous rotation of the conical storage hopper and the up and down movement of the conical grinding hopper, which squeezes and grinds the medicine sandwiched between the conical storage hopper and the conical grinding hopper, reducing the labor intensity of manual grinding and improving the grinding effect.

Rotary shaft fixing arms 14 are fixedly connected to the left and right sides of the lower sidewall of the vertical arm 12, respectively. A conical storage hopper 2 is rotatably inserted into the opening at the left end of the base 11. First teeth 21 are evenly formed on the outer circumferential wall of the upper opening of the conical storage hopper 2. A hammer is suspended inside the conical storage hopper 2. The grinding mechanism 3 includes a conical grinding bucket 31. The taper and bottom of the conical grinding bucket 31 match the taper and bottom of the conical storage hopper 2. The inner sidewall of the upper opening of the conical grinding bucket 31 is fixedly connected to the front and rear sides of the lower end of the movable plate 32. The left and right sidewalls of the upper part of the movable plate 32 have rectangular through slots 321. The front and rear ends of the upper part of the movable plate 32 are fixedly connected to sliding shafts 33. The front and rear sliding shafts 33 pass through the left end of the horizontal plate 13. The upper end of the sliding shafts 33 is divided into... A spring 34 is fitted with a threaded nut 35 on the upper sliding shaft of the spring 34. A transmission mechanism 4 is rotatably fitted within the rectangular through groove 321. The transmission mechanism 4 includes an eccentric wheel 41, which is movably inserted into the rectangular through groove 321. The eccentric wheel 41 is fixedly fitted to the left end of a horizontal shaft 42. The horizontal shaft 42 is rotatably fitted to the lower ends of the left and right rotating shaft fixing arms 14. A first bevel gear 43 is fixedly fitted to the right end of the horizontal shaft 42. The right end of the transmission mechanism 4 is connected to the drive via the first bevel gear 43. The second bevel gear 52 of the driving mechanism 5 is engaged. The driving mechanism 5 includes a vertical shaft 51. The upper end of the vertical shaft 51 is rotatably inserted into the right end of the horizontal plate 13. The second bevel gear 52 and the driving gear 53 are fixedly mounted on the vertical shaft 51 from top to bottom. The driving gear 53 is engaged with the first tooth 21.

The motor 54 is started, driving the vertical shaft 51 to rotate. Simultaneously, the vertical shaft 51 drives the drive gear 53 and the second conical gear 52 to rotate. The drive gear 53 drives the conical storage hopper 2 to rotate via the first tooth 21. The second conical gear 52 drives the first conical gear 43 to rotate. The first conical gear 43 drives the eccentric wheel 41 to rotate via the horizontal shaft 42. The eccentric wheel 41 is equipped with… The spring 34 drives the moving plate 32 to move up and down, which in turn drives the lower conical grinding hopper 31 to move up and down. This allows the conical storage hopper 2 to rotate while the conical grinding hopper 31 moves up and down, thereby quickly squeezing and grinding the medicine sandwiched between the conical storage hopper 2 and the conical grinding hopper 31. During the grinding process, the medicine powder adhering to the conical surfaces of the conical storage hopper 2 and the conical grinding hopper 31 can also be shaken off by the hammering action of the two. After grinding is completed, the medicine powder can be poured out by holding the U-shaped handle 121.
