Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and more specifically, it relates to a drug mixing machine for animal husbandry and veterinary medicine that is easy to clean. Background Technology

[0002] In animal husbandry and veterinary practice, it is crucial to thoroughly mix powders, premixes, or poorly soluble drugs with water or other solvents. This directly affects the uniformity of the distribution of the drug's active ingredients, ensuring accurate dosage for each animal and avoiding the risk of poor efficacy or excessively high local drug concentrations leading to poisoning due to uneven mixing.

[0003] Existing drug homogenizers still have some drawbacks. Traditional homogenizers typically perform drug metering and initial dissolution directly within a large mixing tank, which is not only inefficient but also prone to metering errors and cross-contamination due to drug splashing and adhesion. This is especially problematic for highly active or low-dose drugs, where uneven initial mixing significantly prolongs the master mixing time and affects the uniformity and accuracy of the final drug concentration. When processing solid drugs, pre-crushing with external tools is usually necessary, increasing operational steps, time and labor costs, and making it difficult to control particle size, leading to dust pollution and drug loss. When fully pulverized drugs are directly added to the main mixing tank, they are prone to clumping and sedimentation, leading to incomplete mixing, affecting drug release and animal medication safety. After drug mixing, the mixing tank needs to be cleaned. Existing mixing tanks rely solely on disassembly or simple rinsing, which is insufficient for thorough cleaning. In particular, premixed feed residues, finely crushed drug powders, and viscous liquids easily adhere to the tank walls, breeding bacteria and causing cross-contamination of drug residues, posing safety risks to the preparation of subsequent batches of drugs. Furthermore, manual scrubbing of hard-to-reach areas is time-consuming and labor-intensive, significantly reducing equipment efficiency. Therefore, there is an urgent need to design an easy-to-clean drug mixing machine for animal husbandry and veterinary medicine to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the problems existing in the prior art, this utility model provides a drug mixer for animal husbandry and veterinary medicine that is easy to clean, in order to solve the technical problems mentioned in the background art, such as the lack of a dedicated pre-mixing mechanism in traditional mixers, which leads to cumbersome operation and high precision risk, and the lack of integrated pre-crushing components, which makes it extremely inconvenient to process lumpy, crystalline or poorly soluble solid drugs.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A veterinary medicine mixing machine for easy cleaning includes a support column, a pre-crushing mechanism, a pre-dispensing mechanism, and a cleaning mechanism. The support column has a mixing tank on its upper surface, a lid on its upper surface, and a first motor on its upper surface. The output end of the first motor is connected to a main shaft, and the main shaft surface has several stirring rods. The cleaning mechanism includes a pull rod, a circular brush, and a limiting component. The pull rod is slidably connected to the lid, and its lower surface is connected to the circular brush, which abuts against the inner wall of the mixing tank. The pre-dispensing mechanism includes a mixing cylinder, a dispensing cylinder, a first valve, and a second valve. The mixing cylinder is located on the upper surface of the lid, and two sets of dispensing cylinders are located on its upper surface. The first valve controls the dispensing cylinder, and the second valve controls the mixing cylinder.

[0006] The present invention is further configured such that the limiting component includes a movable clamping plate, a fixed clamping plate, and bolts. The upper end face of the bucket lid is provided with a fixed clamping plate and a movable clamping plate. The movable clamping plate is connected to the fixed clamping plate by bolts. One side of the pull rod is located between the fixed clamping plate and the movable clamping plate. The limiting component can limit the pull rod. When it is necessary to clean the mixing bucket, the bolts are loosened, the movable clamping plate releases the pull rod, and the brush slides up and down freely to clean the bucket wall. When stirring, the movable clamping plate clamps the pull rod with the fixed clamping plate to avoid interfering with the mixing.

[0007] This invention is further configured such that the pre-crushing mechanism includes a crushing barrel, crushing rollers, a second motor, and a third motor. The crushing barrel is located on the upper surface of the barrel lid. Two sets of crushing rollers are installed inside the crushing barrel, and the crushing rollers are rotatably connected to the inner wall of the crushing barrel. The output shaft of the second motor is connected to one set of crushing rollers, and the output shaft of the third motor is connected to the other set of crushing rollers. The second and third motors rotate in opposite directions. The dual-roller counter-rotation powerfully breaks up agglomerated drugs, solving the problem of inefficiency in manual grinding.

[0008] This invention is further configured such that two sets of baffles are provided above the inner wall of the crushing barrel, forming a feed inlet between the two sets of baffles. The baffle design prevents the medicine from splashing out of the crushing barrel during crushing, thus avoiding waste.

[0009] This invention is further configured such that a filter screen is provided inside the grinding barrel, and the filter screen is located below the grinding roller. The filter screen sieves the ground medicine to ensure that the powder is of uniform fineness and improves the dissolution rate.

[0010] The present invention is further configured such that the mixing tank has a conical concave platform inside. The conical surface guides the liquid medicine to gather towards the center, promoting circulation and mixing, and can guide the liquid medicine to flow out quickly during drainage.

[0011] The present invention is further configured such that the lower end face of the mixing tank is provided with a liquid outlet pipe, and the upper end face of the tank lid is provided with a liquid inlet pipe. The solvent is directly injected through the liquid inlet pipe to avoid contamination when the lid is opened; after mixing, the liquid is discharged directionally through the liquid outlet pipe.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a drug mixing machine for animal husbandry and veterinary medicine that is easy to clean, and has the following beneficial effects: 1. This utility model is equipped with a pre-crushing mechanism. The lumpy medicine is fed into the feed port between the baffles above the crushing barrel. The second motor and the third motor drive two sets of crushing rollers to rotate in opposite directions. The medicine is squeezed and sheared by the rollers. The medicine powder falls to the filter screen. The fine powder that meets the standard passes through the screen and falls into the main mixing barrel. The coarse particles that do not meet the standard remain on the screen surface and continue to be crushed. There is no need for manual additional crushing of medicine, which reduces the workload and ensures that the particle size of the medicine powder is the same, thus improving the mixing efficiency.

[0013] 2. This utility model is equipped with a pre-mixing mechanism, which injects the drug or solvent into two sets of dispensing cylinders, opens the first valve to control the drug to enter the mixing cylinder; the drug is initially mixed and dissolved in the mixing cylinder, and the second valve is opened to inject the premixed drug solution into the mixing tank. The design of the pre-mixing mechanism reduces measurement error and improves the uniformity and accuracy of the drug solution concentration.

[0014] 3. This utility model is equipped with a cleaning mechanism. When the mixing tank is stirring, tighten the bolts, move the clamping plate and fix the clamping plate to press the pull rod, fix the position of the circular brush and avoid interfering with the stirring. After the mixing work is completed, loosen the bolts, move the clamping plate back to release the pull rod, and the pull rod can move freely up and down. The operator holds the pull rod and moves it up and down, thereby driving the circular brush to clean the tank wall. The structure is simple and the cleaning efficiency is improved.
