Description

Technical Field

[0001] The invention relates to the technical field of animal husbandry and veterinary medicine, and in particular to an animal husbandry and veterinary medicine pulverizing device with a screening function. Background Art

[0002] In the field of animal husbandry and veterinary medicine, animals need to be treated with medicine after they become sick. However, unlike human medicine, veterinary medicine is usually in large pieces or granules, which is inconvenient to use directly on animals. Therefore, before the use of veterinary medicine, large pieces of medicinal materials need to be processed by a crushing device to ensure the uniform distribution of the medicine and easy absorption. Traditional veterinary medicine crushing devices often produce a large amount of powder residue when crushing medicinal materials. Most of the existing veterinary medicine crushing devices lack efficient screening functions, resulting in a large amount of impurities and unqualified particles mixed in the crushed medicinal materials, and the crushing structure is not convenient to disassemble and clean, and it is difficult to maintain and maintain on a daily basis; there is also a problem that due to the design of the position on one side when the medicine is put in, the crushing knife on one side is subjected to heavy force during the crushing process, which is easy to break and the crushing is not uniform enough. Summary of the invention

[0003] The disclosed embodiment relates to a livestock and veterinary medicine pulverizing device with a screening function. When the connecting shaft rotates, it drives the protrusion to knock the screen plate, thereby achieving screening and avoiding clogging of the screen holes.

[0007] In at least some embodiments, the crushing part includes a large motor, a connecting shaft and a crushing knife. The outside of the large motor is fixedly connected to a support rod, and a circular hole is opened at the outer end of the support rod. Limiting rods are clamped in the circular holes at opposite left and right positions, and the support rod is clamped in the longitudinal clamping groove. The driving shaft of the large motor is coaxially connected to the connecting shaft, and the outside of the connecting shaft is fixedly connected to the crushing knife. The bottom of the connecting shaft is fixedly connected to an outer baffle plate, and the top surface of the outer baffle plate is a sloped structure. Two knocking rods are welded to the bottom of the connecting shaft. Two sets of crushing knives are provided, and the initial installation positions of the upper and lower sets of crushing knives are radially staggered.

[0008] In at least some embodiments, the sieve plate is located below the pre-crushing part, a through hole larger than the outer diameter of the connecting shaft is provided in the center of the sieve plate, and half of the top surface of the sieve plate close to the bottom of the pre-crushing part is an inclined surface, and half of the top surface away from the bottom of the pre-crushing part is a plane.

The cross-section of the connecting strip is an isosceles triangle structure, and elastic ropes are connected to both ends of the sieve plate, and the ends of the elastic ropes are fixedly connected to the inner wall of the device body. When the large motor 51 is started, the large motor 51 vibrates during operation, thereby causing the device body 1 to vibrate synchronously through the support rod 5101, and the elastic rope 802 allows the sieve plate 8 to swing freely, and the crushed drugs pass through the pre-crushing part 4 and fall to the inclined side of the sieve plate 8, as the sieve plate 8 swings freely.

[0010] In at least some embodiments, a bottom clamping plate is integrally provided on the bottom surface of the device body, a feed barrel is welded to the front side of the device body, the feed barrel is obliquely arranged higher outward and lower inside, a semicircular plate is welded on the upper side of the end of the feed barrel, and the end of the feed barrel is located in the front and upper part of the pre-crushing part, a longitudinal clamping groove is provided on the top of the inner wall of the device body, and a clamping through hole is provided at the bottom of the two longitudinal clamping grooves opposite to each other on the left and right.

[0011] The present invention provides a livestock and veterinary medicine pulverizing device with a screening function, which has the following beneficial effects: When the present invention is in use, after the medicine is put into the feed barrel, a small motor is started through the external circuit control end to drive the rotating rod to rotate, the paddle plate breaks the medicine upward, the medicine collides with the crushing plate to be crushed for the second time, and finally falls downward to be crushed. Through the pre-crushing step, the workload of the crushing parts can be reduced, and the medicine can be crushed better.

[0012] In addition, when the locking assembly is buckled in the left and right directions, the limit rod is inserted into the left and right support rods to fix the position of the large motor. At the same time, it can be disassembled and assembled to facilitate the cleaning of the crushed parts.

[0013] In addition, when the connecting shaft rotates, it drives the knocking rod to rotate, and when it touches the protrusion, it will knock the sieve plate once. The two protrusions are used to balance the stability of the sieve plate during knocking, thereby achieving screening and avoiding clogging of the sieve holes. The side guard strips are used to avoid accumulation of drugs at the corners, thereby ensuring that the drugs are completely screened.

[0014] In addition, when the large motor is started, it vibrates during operation, causing the main body of the device to vibrate synchronously through the support rod. The medicines that have passed through the pre-crushing parts and the crushed parts fall to the inclined side of the sieve plate. With the free swing of the sieve plate, the medicines can be scattered more evenly over the crushing knife, thereby achieving uniform crushing and extending the service life of the crushing knife.
