[0002] When veterinary drugs are produced, the raw materials need to be fully crushed and finally synthesized. For such veterinary drugs, the raw materials usually need to be chopped, then dried, then crushed by a grinder, and finally synthesized. Therefore, the corresponding crushing device needs to be used to fully crush the veterinary drugs.

[0003] By comparing with a veterinary drug production raw material crusher with patent announcement number CN216573287U, in this scheme, a dust absorption and recovery device is used to absorb the dust in the process of Chinese medicine crushing, and the absorbed dust is poured into a round tank. After aggregation and sedimentation in the round tank, the drug dust is discharged from the second valved discharge pipe for recovery, thereby avoiding the waste of Chinese medicine raw materials. However, when this device crushes veterinary drugs, the crushed veterinary drugs may be unqualified and incompletely crushed, and the function of secondary crushing of the veterinary drugs after crushing is lacking, which may reduce the crushing quality of the veterinary drugs and reduce the qualified rate of the veterinary drugs after crushing.

[0027] In this embodiment: the pulverizing mechanism includes a feeding component for feeding veterinary drugs and a pulverizing component for pulverizing the veterinary drugs.

[0028] The unloading assembly includes two symmetrical unloading plates 201 rotatably arranged at the upper end of the crushing box 100. The unloading plates 201 are arranged tilted downward. The two unloading plates 201 fit together to close the unloading opening of the crushing box 100. A unloading cylinder 202 is rotatably installed between the lower end of the unloading plate 201 and the inner wall of the crushing box 100.

[0029] The crushing assembly includes two symmetrical crushing rollers 203 arranged inside the crushing box 100, and multiple crushing gear rings 210 are fixed on the two crushing rollers 203 and are staggered with each other. Transmission gears 204 are fixed to the rear ends of the two crushing rollers 203, and the two transmission gears 204 are meshed with each other. A gear box 205 is provided on the outside of the two transmission gears 204, and a crushing motor 206 is installed at the rotating end of the transmission gear 204. A collecting box 214 is slidably installed at the bottom end of the crushing box 100, and a handle is fixed at the front end of the collecting box 214. A screening assembly for secondary crushing of incompletely crushed veterinary drugs is provided below the crushing rollers 203.

[0030] The screening component includes a sieve plate 207 arranged below the crushing roller 203, the sieve plate 207 is slidably connected to the inner wall of the crushing box 100, the sieve plate 207 is in an inverted V shape, and arc plates 208 are fixed on both sides of the sieve plate 207, the arc plate 208 is slidably connected to the inner wall of the crushing box 100, a return spring is connected between the arc plate 208 and the inner wall of the crushing box 100, a grinding gap is formed between the connection between the arc plate 208 and the sieve plate 207 and the crushing roller 203, a plurality of grinding bumps 209 are fixed on the surface of the arc plate 208, and a driving component for driving the arc plate 208 to move up and down is provided below the arc plate 208.

[0031] The driving assembly includes a rotating shaft 211 arranged below the arc plate 208. The rotating shaft 211 is rotatably connected to the crushing box 100. Two front-to-rear symmetrical cams 212 are fixed on the rotating shaft 211. A rotating motor 213 is installed at the rotating end of the rotating shaft 211. A large amount of veterinary drugs are evenly crushed by the crushing assembly. The feeding amount of veterinary drugs can be effectively controlled by the feeding assembly to ensure that the veterinary drugs are fully crushed. After the veterinary drugs are crushed for the first time, the screening assembly is used to screen the veterinary drugs, and qualified veterinary drugs are collected. Unqualified veterinary drugs are squeezed by the two crushing rollers, so that the two crushing rollers grind and crush the veterinary drugs for the second time, thereby improving the utilization rate and crushing efficiency of the crushing rollers, thereby improving the qualified rate of veterinary drug crushing and improving the crushing quality.

[0032] In this embodiment: the dust removal mechanism includes a dust box 301 arranged on the front side of the crushing box 100, a filter 302 is slidably installed inside the dust box 301, two symmetrical wind hoods 303 are provided at the front end of the dust box 301, a dust fan 304 is provided in the wind hood 303, a handle is fixed on the upper end of the filter 302, the dust fan 304 in the wind hood 303 is driven to rotate, so that a certain negative pressure is generated in the dust box 301, the dust generated during the crushing is adsorbed, and the dust is filtered by the filter 302 inside the dust box 301 to prevent the overflow of dust from polluting the surrounding environment.

[0033] Working principle: First, pour a large amount of veterinary drugs to be crushed between the two feeding plates 201, drive the two feeding cylinders 202 to drive the two feeding plates 201 to move away from each other to open the two feeding plates 201, so that the veterinary drugs fall between the two crushing rollers 203, and the opening and closing of the two feeding plates 201 can be used to control the feeding amount of veterinary drugs, and then drive the crushing motor 206 to drive the crushing roller 203 to rotate, and use the two transmission gears 204 to engage with each other, thereby driving the two crushing rollers 203 to rotate in the opposite direction at the same time, and then driving the multiple crushing gear rings 210 on the two crushing rollers 203 to rotate in the opposite direction, so as to fully crush the veterinary drugs in between, and the crushed veterinary drugs fall onto the sieve plate 207 below, and the qualified veterinary drugs pass through the sieve plate 207 and fall into the collection box 214 below, and the unqualified veterinary drugs remain on the surface of the sieve plate 207.

[0034] Then, the two rotating motors 213 are driven to drive the two rotating shafts 211 to rotate in opposite directions, thereby driving the two cams 212 to rotate in opposite directions. The rotation of the cams 212 will squeeze the arc plates 208 on both sides of the screen plate 207 upward, thereby driving the two arc plates 208 to move up and down intermittently, causing the screen plate 207 to vibrate slightly, which is beneficial to the screening of the crushed veterinary drugs on the surface of the screen plate 207. In addition, the screen plate 207 is in an inverted V shape. When the screen plate 207 floats up and down, the veterinary drugs on the surface of the screen plate 207 are driven to gradually move. It moves to the connection between the screen plate 207 and the arc plate 208, and then moves to the grinding gap between the arc plate 208 and the crushing roller 203. The rotation of the crushing roller 203 and the up and down movement of the arc plate 208 make the arc plate 208 and the crushing roller 203 form a state of mutual extrusion, so that the unqualified veterinary drugs in the grinding gap are ground and crushed for the second time, thereby improving the utilization rate of the unworking surface of the crushing roller 203, improving the crushing efficiency of the crushing roller 203, thereby improving the qualified rate of veterinary drug crushing and improving the crushing quality.

[0035] During the crushing process, the dust collecting fan 304 in the wind hood 303 is driven to rotate, so that a certain negative pressure is generated in the dust collecting box 301, and the dust generated during the crushing is adsorbed. The dust is filtered by the filter net 302 inside the dust collecting box 301 to prevent the dust from overflowing and polluting the surrounding environment.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
