A screening power motor 14 is installed above the screening driving power box 9. The main shaft of the screening power motor 14 is connected to an output shaft through a coupling, and a cam 27 is installed on the output shaft. A matching moving block 28 is arranged on the side of the cam 27. The matching moving block 28 is fixedly connected to the outside of the limiting end plate 30 through a connecting rod. A guide rod 31 passes through a through hole arranged on the limiting end plate 30. A return spring 32 is installed on the outer side of the guide rod 31 in the section between the limiting end plate 30 and the outer wall of the drying and screening box 2. The arrangement of the guide rod 31 is used to ensure the stability of the screening movement process of the screening mesh plate 29.
[0025] Among them, the overall arc surface structure of the granulator screen plate 17 is adapted to the arc surface of the granulator bottom plate 16. Installation side edges 18 are arranged on both sides of the granulator screen plate 17. The installation side edges 18 and the installation groove 19 are fixedly connected through fixing screws 20. The fixing screws 20 are countersunk head screws to facilitate the disassembly, replacement and installation of the granulator screen plate 17.
[0026] The screening driving power box 9 is located at the lower position of the upper support 7 on the side of the drying and screening box 2, and the screening driven box 13 is located at the lower position of the drying air duct 11 on the side of the drying and screening box 2.

[0029] There are two groups of drying air ducts 11 extending into the drying and screening box 2. The length dimension of each part of the drying air duct 11 located in the drying and screening box 2 is adapted to the width dimension of the drying and screening box 2. A plurality of drying nozzles 26 are arranged.
[0030] The working principle of the present utility model is as follows: When processing veterinary drugs into granules, the mixed raw materials are added into the feeding hopper 22 of the screw feeder 3. Through the transportation of the screw mechanism in the screw feeder 3, the raw materials are fed into the metering feeder 4 from the guide cylinder 5. The metering feeder 4 can realize the metering transportation of the raw materials and supply the raw materials to the main body 1 of the granulator uniformly and quantitatively. At the discharge port of the main body 1 of the granulator, there is a cover body with an inverted cone structure, which is convenient for the raw materials to be concentrated in the middle position of the main body 1 of the granulator. The power motor and transmission device in the power box 6 of the granulator drive the granulating roller 21 to rotate, and cooperate with the bottom plate 16 and the screen plate 17 of the granulator to realize the granulation processing of granules. The granules in the main body 1 of the granulator fall onto the first baffle 23 through the screen plate 17 of the granulator. At the inclined lower end of the first baffle 23, there is a drying nozzle. According to the composition and particle size of the veterinary drug, a suitable drying temperature is selected, and hot air is blown to dry the pharmaceutical granules. Through multi-stage baffle flow and hot air drying, the veterinary drug granules can be effectively dried. The dried veterinary drug granules fall on the screening mesh plate 29;
[0031] The main shaft of the screening power motor 14 drives the cam 27 to rotate through a connecting shaft and an output shaft. During the rotation of the cam 27, it contacts with the matching moving block 28. The matching moving block 28 pushes the limiting end plate 30 to move horizontally back and forth. During the movement, the limiting end plate 30 cooperates with the guide rod 31 to ensure the stability of the movement process. The setting of the return spring 32 can not only buffer the extreme positions of the reciprocating movement but also facilitate the reset of the screening mesh plate 29;
[0032] The length dimension of the third baffle 25 is smaller than that of the first baffle 23, ensuring that the granular medicine falls on the screening mesh plate 29 near the middle position during the discharging process. Through the screening of the screening mesh plate 29, the qualified granules are discharged from the granule discharge port 10, and the powdered medicine is discharged from the powder discharge port 15. The discharged powder can be added to the feeding hopper 22 for re-granulation processing;
[0033] The structure of the utility model is reasonably designed and convenient to use. A drying and screening box 2 is arranged below the main box body 1 of the granulator. A drying device and a screening device are arranged in the drying and screening box 2. The granular medicament processed and formed by the granulator can be directly subjected to drying treatment and screening treatment without process turnover, avoiding the medicament pollution caused by turnover. At the same time, the processing efficiency of the granulator can be improved to realize continuous granulation processing. The drying device in the drying and screening box 2 uses hot air in cooperation with a multi-stage baffle. The baffle can effectively extend the residence time of the granule agent in the drying and screening box 2 to ensure the drying effect. At the same time, the agglomerates can also be collided and separated during the process of falling along the baffle. The screening mesh plate 29 can reciprocate under the action of the cam 27 structure, the guide rod 31 and the return spring 32 to effectively screen the granule agent.
