Description

Technical Field

[0001] This utility model relates to the field of veterinary drug screening technology, and in particular to a premixed agent particle screening device. Background Technology

[0002] Veterinary drug screening refers to the screening, testing, and analysis of veterinary drugs through a series of technical means to ensure their safety, effectiveness, and compliance. This process is crucial in veterinary drug research and development, production, quality control, and market supervision.

[0003] A search revealed Chinese patent publication number CN222855946U, which discloses a premixed agent granule screening device. This patent features a screening hopper inside a support frame, and a connecting hopper and a feeding hopper at the top of the support frame. The connecting hopper and feeding hopper facilitate the pouring of premixed agent granules onto the top of the screen, where the material is screened. However, this device has a problem: during screening, some material gets stuck in the screen holes, requiring cleaning of the screen after screening, which affects screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a premix particle screening device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a premixed agent particle screening device includes a workbench 101, a fixing block 102 is fixedly installed on the upper end of the workbench 101, a fixing ring 103 is rotatably connected to the fixing block 102, a fixing cylinder 401 is coaxially fixedly connected to the fixing ring 103, and an adjustment mechanism is provided between the fixing cylinder 401 and the workbench 101.

[0027] A screening mechanism is provided on the fixed cylinder 401. The screening mechanism includes a feed cylinder 402, which is coaxially and fixedly connected to the rear end of the fixed cylinder 401. A screening cylinder 403 is coaxially provided inside the fixed cylinder 401 and is rotatably connected to the feed cylinder 402. A pulley is fixedly installed at one end of the screening cylinder 403 near the feed cylinder 402. A drive wheel 404 is provided on the side of the fixed cylinder 401 near the feed cylinder 402. A transmission mechanism is provided between the drive wheel 404 and the fixed cylinder 401. A belt 405 connects the drive wheel 404 and the pulley. In use, the veterinary drug is poured from the feed cylinder 402 into the screening cylinder 403. Then, the transmission mechanism drives the transmission wheel 404 to rotate. The transmission wheel 404 drives the screening cylinder 403 to rotate through the belt 405, so that the screening cylinder 403 rolls and screens the veterinary drug. The veterinary drug rolls and collides continuously in the screening cylinder 403 to prevent the veterinary drug from getting stuck in the holes of the screening cylinder 403. At the same time, the adjusting mechanism drives the fixed cylinder 401 to rotate around the fixed block 102, so that the veterinary drug rolls towards the front end in the screening cylinder 403, and the screen holes are cleared by gravity and centrifugal force.

[0028] The transmission mechanism includes a fixed plate 501, which is fixedly installed on the upper end of the fixed cylinder 401. A transmission motor 502 is fixedly installed at the front end of the fixed plate 501. The output shaft of the transmission motor 502 is coaxially and fixedly connected to the transmission wheel 404. The transmission motor 502 drives the transmission wheel 404 to rotate.

[0029] The front end of the fixed cylinder 401 is fixedly connected to the discharge pipe 601, which is rotatably connected to the screening cylinder 403. The front end of the fixed cylinder 401 has multiple through grooves 602, which are evenly distributed around the discharge pipe 601. After screening, large particles of veterinary medicine enter the discharge pipe 601 from the screening cylinder 403 and are discharged from the discharge pipe 601. Small particles of veterinary medicine fall into the fixed cylinder 401 and are discharged from the through grooves 602.

[0030] The adjustment mechanism includes a lead screw 201, which is rotatably connected inside the worktable 101. An adjustment motor 202 is fixed at the rear end of the worktable 101, and the output shaft of the adjustment motor 202 is fixedly connected to the lead screw 201.

[0031] The lead screw 201 is threadedly connected to an adjusting block 301. The upper end of the adjusting block 301 is rotatably connected to two connecting plates 302. The lower end of the connecting plates 302 is inclined toward the adjusting motor 202.

[0032] A mounting block is fixed to the side of the fixed cylinder 401 near the lead screw 201. The upper ends of the two connecting plates 302 are rotatably connected to the mounting block. When it is necessary to adjust the tilt angle of the fixed cylinder 401, the adjusting motor 202 drives the lead screw 201 to rotate. The lead screw 201 and the adjusting block 301 are threaded together, which drives the adjusting block 301 to move towards the front end. This causes the adjusting block 301 to push the fixed cylinder 401 to move through the connecting plate 302, thereby increasing the angle between the fixed cylinder 401 and the worktable 101.

[0033] A cover 7 is hinged to the rear end of the feed cylinder 402. A handle is fixed on the cover 7. Flipping the cover 7 causes it to rotate around the hinge axis of the feed cylinder 402.

[0034] Working principle: During use, flipping the cylinder cover 7 causes it to rotate around the hinge shaft of the feed cylinder 402, pouring the veterinary drugs from the feed cylinder 402 into the screening cylinder 403. Then, the drive motor 502 drives the drive wheel 404 to rotate, which in turn drives the screening cylinder 403 to rotate via the belt 405. This causes the screening cylinder 403 to tumble and sift the veterinary drugs. The drugs continuously tumble and collide within the screening cylinder 403, improving screening efficiency and preventing them from getting stuck in the holes of the screening cylinder 403. When the tilt angle of the fixed cylinder 401 needs to be adjusted, the adjusting motor 202 drives the lead screw 201 to rotate. The lead screw 201 and the adjusting block 301 are threaded together, which drives the adjusting block 301 to move towards the front end. This causes the adjusting block 301 to push the fixed cylinder 401 to move through the connecting plate 302. This increases the angle between the fixed cylinder 401 and the worktable 101, driving the fixed cylinder 401 to rotate around the fixed block 102. This causes the veterinary drug to roll towards the front end in the screening cylinder 403. Gravity and centrifugal force clear the blockage of the screen holes. After screening, large particles of veterinary drug enter the discharge pipe 601 from the screening cylinder 403 and are discharged from the discharge pipe 601. Small particles of veterinary drug fall into the fixed cylinder 401 and are discharged from the through groove 602.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
