Description

Technical Field

[0001] The utility model belongs to the technical field of crushing equipment, and particularly relates to a powder grinding equipment for aquatic veterinary drugs. Background Art

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

[0003] The traditional Chinese veterinary drugs commonly used in traditional Chinese veterinary clinical practice are usually made from fresh medicinal materials. During the processing of veterinary drugs, it is necessary to crush and grind the raw medicinal materials. On the one hand, it can reduce the particle size of the drugs, increase the surface area of the drugs, and improve the bioavailability of the drugs. On the other hand, it can improve the uniformity of the mixture between the drugs and different drug components. Therefore, it is necessary to use grinding equipment to crush and grind the raw medicinal materials. The traditional grinding equipment includes a box body, and a feeding hopper communicated with the box body is fixedly connected to the upper end of the box body. A pair of meshing crushing rollers are rotatably installed in the box body. The raw medicinal materials fall onto the meshing part of the two crushing rollers through the feeding hopper for crushing and grinding operations.

[0004] It is found in the actual working process that the above-mentioned grinding equipment can only perform a single crushing and grinding operation on the materials, the crushing and grinding are not thorough enough, and a large number of large-particle particles that do not meet the requirements are likely to appear, resulting in low work efficiency and low yield; in addition, in the actual working process, a group of crushing rollers crush and extrude the medicinal materials for a long time, and the two crushing rollers tend to move outwards. If the two crushing rollers are under the pressure of being extruded outwards for a long time, they are likely to displace, resulting in an increase in the gap between the two crushing rollers, thus reducing the crushing efficiency and the yield, and further reducing the crushing and grinding efficiency; in addition, the raw material powder after crushing is easy to accumulate and block at the discharge port, and it is necessary to manually dredge the discharge port, which not only delays the work, but also has a certain danger. Therefore, it is urgent to design a powder grinding equipment for aquatic veterinary drugs to solve the above problems. Summary of the Utility Model

A transmission belt 2-3 is connected between the driving pulley 2-2 and the driven pulley 2-4.

[0030] Working process:

[0031] In the actual working process, the medicinal material raw materials are put into the feed hopper 13. Under the guiding action of the two groups of upper guiding plates 12, the medicinal material raw materials fall between the fixed large crushing roller 9 and the movable large crushing roller 10. The fixed large crushing roller 9 and the movable large crushing roller 10 rotating towards each other perform a preliminary crushing operation on the materials falling between them; under the guiding action of the two groups of lower guiding plates 8, the materials that have been preliminarily crushed by the fixed large crushing roller 9 and the movable large crushing roller 10 fall between the two groups of small crushing rollers 6. The two groups of small crushing rollers 6 rotating towards each other can perform a secondary crushing operation on the materials that have been preliminarily crushed, realizing multiple crushing and grinding operations of the medicinal materials;

[0032] The crushed powdery materials fall onto the inclined bottom surface of the discharge hopper 5. After crushing for a period of time, the material pushing motor 2-1 is started to drive the rotating material pushing device 4 to rotate. The rotating rotating material pushing device 4 can push the powdery materials piled up on the inclined surface of the discharge hopper 5, so that the materials slide down smoothly, avoiding the materials from accumulating on the bottom surface of the discharge hopper 5 and affecting the normal operation of the grinding equipment. At the same time, there is no need for manual dredging of the discharge port of the discharge hopper 5, and the equipment has strong safety;

[0033] In addition, during the actual working process, the gap between the fixed large crushing roller 9 and the movable large crushing roller 10 can be adjusted regularly to prevent the fixed large crushing roller 9 and the movable large crushing roller 10 from shifting due to the outward extrusion pressure over a long time, which may increase the gap between the fixed large crushing roller 9 and the movable large crushing roller 10 and thus affect the crushing efficiency and the yield rate. That is, by rotating the distance-adjusting handwheel 7-1 to drive the rotation of the distance-adjusting lead screw 7-2, the rotating distance-adjusting lead screw 7-2 can drive the front slider 7-3 installed thereon to move towards the fixed large crushing roller 9, thereby preventing the gap between the fixed large crushing roller 9 and the movable large crushing roller 10 from being too large. In addition, during the crushing process, a large amount of medicinal material raw materials often adhere to the fixed large crushing roller 9 and the movable large crushing roller 10. In order not to affect the normal operation of the crushing operation, it is necessary to clean the fixed large crushing roller 9 and the movable large crushing roller 10 regularly. At this time, the distance-adjusting lead screw 7-2 needs to be rotated in the reverse direction to make the front slider 7-3 move away from the fixed large crushing roller 9, thereby increasing the gap between the fixed large crushing roller 9 and the movable large crushing roller 10 and facilitating the cleaning operation of the two by the staff.
