Description

Technical Field

[0001] The present invention belongs to the technical field of veterinary drug production, and relates to a screening device, specifically a veterinary drug screening device. Background Art

[0002] Veterinary drugs refer to substances used for preventing, treating, or diagnosing animal diseases or for purposefully regulating the physiological functions of animals. Veterinary drugs mainly include: serum products, vaccines, diagnostic products, microecological products, traditional Chinese medicinal materials, traditional Chinese patent medicines, chemical drugs, antibiotics, biochemical drugs, radioactive drugs, and external pesticides, disinfectants, etc.

[0003] During the production and processing of veterinary drug granules, multiple strict production and processing procedures are required, and a granule screening device is often needed to achieve the screening process of veterinary drug granules.

[0004] After the inventor's search, a veterinary drug screening device is disclosed in a patent document with the publication number CN211563627U, which includes a frame. A box body is arranged on the frame, a feeding port is arranged above the box body, and relatively sliding baffles are arranged inside the feeding port. Inside the box body, three layers of screening mesh plates are arranged from top to bottom in sequence, and the inner diameters of the mesh holes of the three layers of screening mesh plates decrease from top to bottom in sequence. Although this solution can freely select a screening mesh plate with a suitable mesh hole inner diameter according to actual needs to screen materials of different particle sizes, however, when the materials are put onto the screening mesh plate, it is easy to cause the materials to accumulate on the screening mesh plate, and the relatively fixed screening mesh plate is also not conducive to the rapid screening of the materials, further resulting in the accumulation of materials on the screening mesh plate, there is a problem of insufficient screening efficiency, and the efficiency of the screening equipment directly affects the production efficiency of the entire veterinary drug product. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide a veterinary drug screening device, aiming to solve the technical problems proposed in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions.

[0007] A veterinary drug screening device, which includes a conveying mechanism and a screening mechanism. The conveying mechanism is used to send the veterinary drug materials to be screened to the screening mechanism, so as to further use the screening mechanism to screen the veterinary drug materials to obtain veterinary drug materials of the required size; The conveying mechanism is arranged on the top of the frame; The screening mechanism is arranged on one side of the lower part of the frame; The screening mechanism includes a screening component, and the screening component includes a screening mesh plate; The conveying mechanism includes a material control cylinder. The top opening of the material control cylinder communicates with the bottom opening of the feeding box, enabling the veterinary drug material in the feeding box to be added into the material control cylinder. The feeding box is located above the material control cylinder, and both the feeding box and the material control cylinder are fixedly installed on the top of the frame. One side of the bottom of the material control cylinder is connected and provided with a discharge pipe, and the other end of the discharge pipe is located above the screening mesh plate. In some embodiments of the present invention, a material control roller is coaxially rotatably arranged in the material control cylinder. A plurality of measuring cavities are equidistantly arranged on the material control roller. By rotating the material control roller in the material control cylinder, when the measuring cavity moves to correspond to the bottom opening of the feeding box, the veterinary drug material in the feeding box enters the measuring cavity. As the material control roller continues to rotate, when the measuring cavity filled with the veterinary drug material moves to the position of the discharge pipe, the veterinary drug material in the current measuring cavity is discharged through the discharge pipe and falls onto the screening mesh plate.

[0008] In some embodiments of the present invention, a position-adjustable material control block is arranged in each measuring cavity. By adjusting the position of the material control block in the corresponding measuring cavity, the amount of veterinary drug material that the measuring cavity can accommodate can be adjusted, that is, the amount of material that the measuring cavity can accommodate can be adjusted according to needs to control the amount of material supplied by the conveying mechanism to the screening mechanism at one time. A support channel is arranged in the measuring cavity, and the material control block penetrates and slides into the measuring cavity through the support channel. An operating shaft is rotatably arranged in the central shaft cavity of the material control roller. One end of the operating shaft is coaxially and fixedly connected with an operating handle, and the operating shaft is also rotatably connected with a hexagonal seat. The hexagonal seat is coaxially and fixedly installed in the central shaft cavity of the material control roller. That is, in the present invention, the operating shaft can be driven to rotate by the operating handle without affecting the operating state of the material control roller. The material control roller is coaxially and fixedly connected with a driven large gear.

[0009] In some embodiments of the present invention, a driving bevel gear is coaxially and fixedly installed on the operating shaft. An internal thread sleeve is fixedly installed in the material control block. The internal thread sleeve is sleeved on an external threaded rod in a threaded connection manner. The other end of the external threaded rod is rotatably connected with the operating shaft. A driven bevel gear is coaxially installed on the external threaded rod, and the driven bevel gear meshes with the driving bevel gear. Therefore, when it is necessary to adjust the position of the material control block in the measuring cavity, only the operating handle needs to be used to rotate the operating shaft, which can drive the corresponding external threaded rod to rotate, and then push the material control block to generate displacement, so as to adjust the position of the material control block in the measuring cavity.

[0010] In some embodiments of the present invention, the screening mesh plate is installed on the screening frame. The side of the screening frame has a frame to prevent the veterinary drug material on the screening mesh plate from falling off during screening. A support roller is also arranged at the bottom of the screening frame. The support roller is slidably arranged on the support platform, so that the screening frame can slide on the support platform.

[0011] In some embodiments of the present invention, a guiding support rod is further fixedly arranged on the supporting platform. A guiding track is arranged on the outer side surface of the screening frame. The top end of the guiding support rod is fixedly installed with a guiding slider, and the guiding slider is matched with the guiding track and is slidably arranged in the guiding track to guide the movement of the screening frame relative to the supporting platform and improve the stability when the screening mechanism operates.

[0012] In some embodiments of the present invention, the veterinary medicine screening device further includes a conveying slideway. The conveying slideway is supported and installed on the supporting platform, and the conveying slideway is of an inclined structure and is located directly below the screening mesh plate to centrally collect the veterinary medicine materials of the required size that fall through the screening of the screening mesh plate.

[0013] In some embodiments of the present invention, the screening mechanism further includes a push-pull assembly for pushing the screening mesh plate to perform reciprocating movements; the push-pull assembly includes a first driving shaft. The first driving shaft is rotatably supported on the machine frame, and one end of the first driving shaft is fixedly connected to one end of a swing rod. Among them, the swing rod is connected along the radial direction of the first driving shaft so that when the first driving shaft rotates, the other end of the swing rod makes a circular motion around the axis of the first driving shaft; The push-pull assembly further includes a push-pull rod. One end of the push-pull rod is hinged to the frame of the screening frame, and the other end of the push-pull rod is hinged to the other end of the swing rod. When the swing rod makes a circular motion, under the pulling action of the push-pull rod, the screening frame is pushed to reciprocate on the supporting platform to improve the screening efficiency of the veterinary medicine materials placed on the screening mesh plate.

[0014] In some embodiments of the present invention, a driving motor for driving the first driving shaft and the material control roller to act simultaneously is further installed on the machine frame, so that while the conveying mechanism feeds materials to the screening mechanism, the screening mechanism also synchronously performs the screening action of the materials, thereby improving the overall efficiency of the veterinary medicine screening device of the present invention in screening veterinary medicine materials.

[0015] In some embodiments of the present invention, the output shaft of the driving motor is connected to the first driving shaft by a belt drive mode. Specifically, a first driving wheel is installed on the output shaft of the driving motor, and a second driving wheel is coaxially and fixedly installed on the first driving shaft. The second driving wheel and the first driving wheel are connected by a first transmission belt; correspondingly, the first driving shaft and the second driving shaft are also connected by a belt drive mode. A driving small gear is coaxially and fixedly installed on the second driving shaft, and a driven large gear is coaxially and fixedly installed on the material control roller. The driven large gear meshes with the driving small gear. When the first driving shaft rotates, the material control roller is synchronously driven to rotate, that is, while the conveying mechanism feeds materials to the screening mechanism, the screening mechanism also synchronously performs the screening action of the materials.

[0016] Compared with the prior art, the beneficial effects of the veterinary drug screening device of the present invention are as follows: First, the present invention uses a screening mechanism to screen veterinary drug materials. Among them, while the conveying mechanism feeds materials to the screening mechanism, the screening mechanism also synchronously performs the screening action of the materials, so as to improve the overall efficiency of the veterinary drug screening device of the present invention in screening veterinary drug materials; Second, the screening mechanism of the present invention also uses a push-pull component to push the screening frame to reciprocate on the support platform, so as to improve the screening efficiency of the veterinary drug materials placed on the screening mesh plate; Third, in the conveying mechanism of the present invention, a position-adjustable control block is provided in each metering cavity. By adjusting the position of the control block in the corresponding metering cavity, the amount of veterinary drug materials that the metering cavity can accommodate can be adjusted, that is, the amount of materials that the metering cavity can accommodate can be adjusted according to needs, so as to control the amount of materials fed by the conveying mechanism to the screening mechanism at one time.
