Description

Technical Field

[0001] This utility model relates to the field of veterinary drug raw material screening technology, specifically, to a veterinary drug raw material screening device. Background Technology

[0002] In the production and processing of veterinary drugs, the purity of raw materials directly determines the quality, efficacy, and safety of the veterinary drug products. Therefore, fine screening of veterinary drug raw materials is an indispensable and crucial process. The core purpose of screening is to remove impurities such as stones, metal fragments, and agglomerated particles from the raw materials, while ensuring that the particle size of the screened raw materials is uniform and consistent, meeting the stringent requirements of subsequent processes such as mixing, granulation, and molding.

[0003] Currently, most veterinary drug raw material screening devices on the market use vibrating screens, rotary vibrating screens, or drum screens as their core screening mechanisms. Their basic working principle is to use the inertial force generated by mechanical vibration or rotation to make the raw materials throw or slide on the screen surface. The raw materials are separated from impurities by utilizing the difference in the aperture of the screen. However, the screened raw materials still remain on the surface of the screen plate. The raw materials on the screen plate are generally collected manually, which has low collection efficiency and thus affects the screening efficiency of veterinary drug raw materials. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a veterinary drug raw material sieving device to solve the technical problem of low collection efficiency of raw materials after sieving in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a veterinary drug raw material sieving device, including a sieving seat with a sieving port. Multiple support legs are installed on the bottom sidewall of the sieving port. The device also includes a support frame, a support bracket, a collection bucket, a coarse sieving mechanism, a fine sieving mechanism, and a stirring mechanism. The support frame is disposed on the top side of the sieving seat, and the support bracket is fixedly disposed between the two opposite sidewalls of the support frame and the sieving seat. The collection bucket is disposed on the bottom side of the sieving seat and aligned with the sieving port. The coarse sieving mechanism is disposed within the sieving port for coarse sieving of the veterinary drug raw material. The fine sieving mechanism is disposed within the sieving port for fine sieving of the veterinary drug raw material. The stirring mechanism is disposed on the support frame for stirring the veterinary drug raw material within the sieving port.

[0006] Preferably, the coarse screening mechanism includes a fixed ring and a mounting ring. The fixed ring is fixedly disposed on the inner wall of the screening port, and the mounting ring is slidably disposed within the screening port. A first screen plate is installed on the inner wall of the mounting ring. A first bolt is provided through the mounting ring and the fixed ring. It should also be noted that the impurities intercepted on the first screen plate are relatively large. These impurities are few in number but large in volume, making them relatively easy to collect. Therefore, manual collection is convenient, and no impurity collection mechanism is designed here.

[0007] Furthermore, the fine screening mechanism includes a mounting groove, a mounting frame, and a mounting plate. The mounting groove is formed on the side wall of the screening seat, the screening port passes through the mounting groove, the mounting frame is slidably disposed in the mounting groove, a second screen plate is fixedly disposed on the inner wall of the mounting frame, the mounting plate is fixedly disposed on the mounting frame, and a second bolt passes through between the mounting plate and the screening seat.

[0008] Furthermore, the stirring mechanism includes a support plate, a stirring column, stirring rods, and a rotating mechanism. The support plate is slidably disposed within the support frame, and a support opening is provided on the bottom side wall of the support frame, the support opening penetrating the first sieve plate. The stirring column is rotatably disposed on the bottom side wall of the support plate, and the bottom end of the stirring column extends through the support opening into the mounting frame. Multiple stirring rods are fixedly disposed on the top side of both the first sieve plate and the second sieve plate. The rotating mechanism is disposed on the support plate and is used to drive the stirring column to rotate.

[0009] Furthermore, an electric push rod is installed on the support frame, and the output end of the electric push rod is fixedly connected to the support plate.

[0010] Based on the above scheme, the rotating mechanism includes a first cavity, a first gear, a second gear, and a driving mechanism. The first cavity is opened in the support plate. The first gear is rotatably disposed in the first cavity and is fixedly connected to the stirring column. The second gear is rotatably disposed in the first cavity and meshes with the first gear. The driving mechanism is disposed on the support plate and is used to drive the second gear to rotate.

[0011] Based on the above scheme, the driving mechanism includes a first driving port, a second driving port, a driving prism, and a motor. The first driving port is opened on the support plate, the second driving port is opened on the second gear, the driving prism is rotatably disposed in the support frame, the driving prism passes through the first driving port and the second driving port, the driving prism and the second driving port are connected by a clearance fit, the motor is installed on the top side wall of the support frame, and the output end of the motor is fixedly connected to the driving prism.

[0012] Based on the above scheme, a telescopic tube is fitted onto the driving prism, and the two ends of the telescopic tube are fixedly connected to the support plate and the side wall of the support frame, respectively.

[0013] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, by setting up a coarse sieve mechanism and a fine sieve mechanism, after the veterinary drug raw materials are added into the sieve opening, the first sieve plate can first intercept the large volume impurities in the veterinary drug raw materials, and then the second sieve plate can filter the small volume impurities and powder in the veterinary drug raw materials. The filtered small volume impurities and powder can fall into the collection bucket through the sieve opening for collection. As for the veterinary drug raw materials on the second sieve plate, they can be collected by rotating the second bolt and pulling the mounting frame out of the mounting groove. Secondly, the impurities intercepted on the first sieve plate are relatively large volume impurities. These impurities are few in number but large in volume, making them relatively easy to collect. Therefore, manual collection is more convenient, which solves the problem of collecting veterinary drug raw materials that meet the size requirements after sieving. 2. In this utility model, the stirring mechanism allows the support plate and stirring column to move vertically via the operation of the electric push rod. This allows the stirring column to be lifted before the mounting frame is pulled out of the mounting slot, thus preventing the stirring column from obstructing the movement of the mounting frame. During the screening process, the motor drives the drive prism to rotate. Simultaneously, the clearance between the drive prism and the second drive port drives the second gear, the first gear, and the stirring column to rotate. This allows the stirring rods on the surface of the stirring column to stir the veterinary drug raw materials, thereby improving screening efficiency. Attached Figure Description

[0022] like Figures 1-5 As shown, this invention illustrates a veterinary drug raw material sieving device according to one embodiment of the present invention. The device includes a sieving base 1 with a sieving port 2. Multiple support legs 3 are mounted on the bottom side wall of the sieving port 2. It also includes a support frame 4, a support bracket 5, a collection bucket 6, a coarse sieving mechanism, a fine sieving mechanism, and a stirring mechanism.

The collection bucket 6 is located on the bottom side of the sieving base 1 and is aligned with the sieving port 2. The coarse sieving mechanism is located inside the sieving port 2 for coarse sieving of the veterinary drug raw material. The fine sieving mechanism is located inside the sieving port 2 for fine sieving of the veterinary drug raw material. The stirring mechanism is located on the support frame 4 for stirring the veterinary drug raw material inside the sieving port 2.

[0023] Reference Figures 1-3The coarse screening mechanism includes a fixed ring 7 and a mounting ring 8. The fixed ring 7 is fixedly installed on the inner wall of the screening port 2, and the mounting ring 8 is slidably installed in the screening port 2. A first screen plate 9 is installed on the inner wall of the mounting ring 8. A first bolt passes through the mounting ring 8 and the fixed ring 7. It should be noted that the first screen plate 9 traps relatively large impurities. These impurities are few in number but large in volume, making them easy to collect manually. Therefore, no impurity collection mechanism is designed here. The fine screening mechanism includes a mounting groove 10, a mounting frame 11, and a mounting plate 13. The mounting groove 10 is opened on the side wall of the screening seat 1, and the screening port 2 passes through the mounting groove 10. The mounting frame 11 is slidably installed in the mounting groove 10, and a second screen plate 12 is fixedly installed on the inner wall of the mounting frame 11. The mounting plate 13 is fixedly installed in the mounting seat 1. A second bolt is installed through the mounting plate 13 and the sieve seat 1 on the mounting frame 11. Specifically, after the veterinary drug raw material is added into the sieve opening 2, large-volume impurities in the veterinary drug raw material can first be intercepted by the first sieve plate 9, and then small-volume impurities and powder in the veterinary drug raw material can be filtered by the second sieve plate 12. The filtered small-volume impurities and powder can fall into the collection bucket 6 through the sieve opening 2 for collection. As for the veterinary drug raw material on the second sieve plate 12, it can be collected by rotating the second bolt and pulling the mounting frame 11 out of the mounting groove 10. Secondly, the impurities intercepted on the first sieve plate 9 are relatively large-volume impurities. These impurities are few in number but large in volume, making them relatively easy to collect. Therefore, manual collection is more convenient, which solves the problem of collecting veterinary drug raw materials that meet the size requirements after sieving.

[0024] Reference Figures 3-5The stirring mechanism includes a support plate 14, a stirring column 15, stirring rods 16, and a rotating mechanism. The support plate 14 is slidably disposed within a support frame 4. A support opening is provided on the bottom side wall of the support frame 4, penetrating the first sieve plate 9. The stirring column 15 is rotatably disposed on the bottom side wall of the support plate 14, with its bottom end extending through the support opening into the mounting frame 11. Multiple stirring rods 16 are fixedly disposed on the top sides of both the first sieve plate 9 and the second sieve plate 12. The rotating mechanism is disposed on the support plate 14 and is used to drive the stirring column 15 to rotate. An electric push rod is mounted on the support frame 4. The output end of the push rod is fixedly connected to the support plate 14. The rotating mechanism includes a first cavity 17, a first gear 18, a second gear 19, and a driving mechanism. The first cavity 17 is opened inside the support plate 14. The first gear 18 is rotatably disposed in the first cavity 17 and is fixedly connected to the stirring column 15. The second gear 19 is rotatably disposed in the first cavity 17 and meshes with the first gear 18. The driving mechanism is disposed on the support plate 14 and is used to drive the second gear 19 to rotate. The driving mechanism includes a first driving port 20, a second driving port 21, a driving prism 22, and an electric drive mechanism. The motor 23 has a first drive port 20 on the support plate 14 and a second drive port 21 on the second gear 19. A drive prism 22 is rotatably mounted inside the support frame 4, passing through both the first drive port 20 and the second drive port 21. The drive prism 22 and the second drive port 21 are connected with a clearance fit. The motor 23 is mounted on the top side wall of the support frame 4, and its output end is fixedly connected to the drive prism 22. A telescopic tube is fitted onto the drive prism 22, and both ends of the telescopic tube are fixedly connected to the support plate 14 and the side wall of the support frame 4, respectively. Specifically, the operation of the electric push rod... The motor 23 drives the support plate 14 and the stirring column 15 to move in the height direction, thereby lifting the stirring column 15 before the mounting frame 11 is pulled out of the mounting groove 10, thus avoiding the stirring column 15 from obstructing the movement of the mounting frame 11. During the screening process, the operation of the motor 23 can drive the drive prism 22 to rotate. At the same time, through the gap cooperation between the drive prism 22 and the second drive port 21, the second gear 19, the first gear 18 and the stirring column 15 are driven to rotate. Thus, the veterinary drug raw materials can be stirred by the stirring rod 16 on the surface of the stirring column 15, thereby improving the screening efficiency.

[0025] In this embodiment, during use, after the operator adds the veterinary drug raw material to the sieve opening 2, the large-volume impurities in the veterinary drug raw material are first intercepted by the first sieve plate 9, and then the small-volume impurities and powder in the veterinary drug raw material are filtered by the second sieve plate 12. The filtered small-volume impurities and powder fall into the collection bucket 6 through the sieve opening 2 for collection. As for the veterinary drug raw material on the second sieve plate 12, it can be collected by rotating the second bolt and pulling the mounting frame 11 out of the mounting groove 10. Secondly, the impurities intercepted on the first sieve plate 9 are relatively large-volume impurities. These impurities are few in number but large in volume, making them relatively easy to collect manually. This solves the problem of collecting veterinary drug raw materials that meet the required size after screening. The operation of the electric push rod can drive the support plate 14 and the stirring column 15 to move in the height direction, so that the stirring column 15 can be lifted before the mounting frame 11 is pulled out of the mounting slot 10, thereby avoiding the stirring column 15 from obstructing the movement of the mounting frame 11. During the screening process, the operation of the motor 23 can drive the drive prism 22 to rotate. At the same time, through the gap cooperation between the drive prism 22 and the second drive port 21, the second gear 19, the first gear 18 and the stirring column 15 are driven to rotate. Thus, the veterinary drug raw materials can be stirred by the stirring rod 16 on the surface of the stirring column 15, thereby improving the screening efficiency.
