The lower ring surface of the sliding sleeve group 34 is integrally connected with a reset spring 342, and is slidably limited in the ring groove provided on the side of the spray connection pipe 25 in cooperation with the reset spring 342.

[0022] During operation, the solid raw material of veterinary drugs to be processed is firstly put into the tank body 11 from the feed port 113, and the raw material falls on and is stored inside the screen 33. The tank body 11 is closed, and the hydraulic cylinder 21 is started, and its output rod is retracted, and the screw rod 22 is lifted up, and the screw rod 22 passes through the butterfly hole plate 231, driving the driving pipe 23 to move downward, driving the spray connecting pipe 25, the grinding body 24, the cleaning sealing ring sleeve 31, the sheath 32 and the screen 33 to move downward, and the screen 33 is docked with the magnetic stripe base 112 for adsorption and fixation. , the grinding body 24 and the spray connecting pipe 25 continue to move downward. At this time, the cleaning sealing ring sleeve 31 pulls the sliding sleeve group 34 by rotating the connecting frame 341, and the sliding sleeve group 34 drags the piston rod 343 to slide upward along the inner wall of the hydraulic gap 251. Negative pressure appears inside the hydraulic gap 251, and the liquid replenishing valve 3432 opens. The liquid in the liquid storage tube 233 enters the liquid replenishing channel 3431 and then enters the hydraulic gap 251. When the piston rod 343 moves to the uppermost end of the sliding hole inside the spray connecting pipe 25 or the sliding sleeve group When the grinding body 24 moves to the uppermost side along the annular groove, the grinding body 24 and the screen 33 are at the minimum spacing and are about to fit together. During this process, the grinding body 24 cooperates with the screen 33 to rotate and grind the raw material. If the raw material resistance is large or the grinding body 24 cannot continue to rotate and move downward, the hydraulic cylinder 21 pushes down the screw rod 22, and the screw rod 22 cooperates with the butterfly hole plate 231 to drive the driving pipe 23 to move upward, and the grinding body 24 and the spray connecting pipe 25 move upward at the same time. Since the screen 33 is magnetically attracted to the magnetic stripe base 112, the grinding body 24 and the spray connecting pipe 25 are connected to the magnetic stripe base 112. , the cleaning sealing ring sleeve 31, the sheath 32 and the screen 33 do not move up, and the sliding sleeve group 34 moves down along the side ring groove of the spray connecting pipe 25 under the pull of the cleaning sealing ring sleeve 31, opening the output end of the sprayer 252, and at the same time, the sliding sleeve group 34 drags the piston rod 343 down along the hydraulic gap 251, compressing the storage space of the hydraulic gap 251, forcing the liquid to be sprayed into the tank body 11 through the sprayer 252, thereby cooling, reducing dust and increasing humidity for the tank body 11, reducing the generation of static electricity and reducing the risk of dust explosion.

[0023] In summary, through the arrangement of the tank body 11, the cooling liquid flow interlayer 111, the magnetic stripe base 112, the pressurized water supply pipe 115, the mobile auxiliary bracket 116, the hydraulic cylinder 21, the screw rod 22, the drive pipe 23, the butterfly hole plate 231, the limited sliding hole 232, the liquid storage pipe 233, the one-way valve 2331, the grinding body 24, the spray connecting pipe 25, the hydraulic gap 251, the sprayer 252, the sealing slide 253, the cleaning sealing ring sleeve 31, the sliding sleeve group 34, the rotating connecting frame 341, the reset spring 342, the piston rod 343, the liquid replenishing channel 3431 and the liquid replenishing valve 3432, not only can the traction be pulled on the hydraulic cylinder 21, but also the traction can be pulled on the hydraulic cylinder 21. When the hydraulic cylinder 21 is pushed down, the driving tube 23, the grinding body 24 and the spray connecting tube 25 are pushed down and driven to rotate rapidly in cooperation with the butterfly plate 231, and the cleaning seal ring sleeve 31, the sheath 32, the screen 33, the sliding sleeve group 34 and the piston rod 343 are combined to realize the grinding and crushing of the raw materials and the supply of liquid to the inside of the hydraulic gap 251. Moreover, when the hydraulic cylinder 21 is pushed down, while the driving tube 23, the grinding body 24 and the spray connecting tube 25 are moved up, the adsorption effect of the magnetic stripe base 112 on the screen 33 is utilized to make the cleaning seal ring sleeve 31 drag the sliding sleeve group 34 to slide along the spray connecting tube 25, and drag the piston rod 343 The liquid in the hydraulic gap 251 is compressed, so that the liquid is sprayed outward through the sprayer 252 under pressure, so as to cool down, reduce dust and increase humidity in the space of the tank body 11, reduce static electricity and reduce the risk of dust explosion, and improve the safety of veterinary drug production; through the arrangement of the tank body 11, the magnetic stripe base 112, the hydraulic cylinder 21, the screw rod 22, the drive tube 23, the butterfly hole plate 231, the limited sliding hole 232, the liquid storage tube 233, the grinding body 24, the spray connecting pipe 25, the cleaning sealing ring sleeve 31, the sheath 32, the screen 33, the sliding sleeve group 34, the rotating connecting frame 341 and the reset spring 342, the hydraulic cylinder 21 can be used to clean the liquid in the hydraulic gap 251. Under the action of the up and down push-pull traction of 21, in cooperation with the butterfly plate 231, the driving tube 23, the grinding body 24 and the spray connecting tube 25 are driven to rotate, so that they can carry the cleaning sealing ring sleeve 31, the sheath 32 and the screen 33 to perform shaking screening of the raw materials while performing the grinding and crushing of the raw materials, so that the crushed raw materials can be output first, reducing the grinding load and friction force of the grinding body 24, and improving the efficiency of raw material grinding. At the same time, the shaking screening method does not need to add a vibration screening auxiliary structure, which not only reduces the cost of the equipment, but also greatly reduces the wear of the screen 33 compared with the current equipment.

[0024] As an embodiment of the present invention, Figure 7As shown, the cleaning sealing ring sleeve 31 is sealingly slidably arranged at the lower part of the tank body 11, and a cleaning brush 3111 for cleaning the inner wall of the tank body 11 is integrally arranged around the side surface close to the inner wall of the tank body 11, an annular airway 311 is opened inside the cleaning sealing ring sleeve 31 along an annular path, and a plurality of L-shaped blowing holes 3113 that penetrate the cleaning sealing ring sleeve 31 are opened on the inner wall of the annular surface and the outer surface of the cleaning sealing ring sleeve 31 along the ring center in an annular array, and a one-way air valve 3112 is arranged inside the blowing hole 3113 to prevent gas backflow.

[0025] During operation, the upwardly moved cleaning sealing ring sleeve 31 cooperates with the cleaning brush 3111 to clean the inner wall of the tank body 11. At the same time, the cleaning sealing ring sleeve 31, the sheath 32 and the screen 33 compress the internal space of the tank body 11, forcing the gas to break through the one-way air valve 3112 and enter the blowing hole 3113. The cleaning brush 3111 blows the inner wall of the tank body 11 for air blowing cleaning, thereby ensuring the cleanliness of the inner wall of the tank body 11 and preventing waste and residue of raw materials.

[0026] To sum up, through the arrangement of the tank body 11, hydraulic cylinder 21, screw rod 22, driving pipe 23, butterfly plate 231, limited sliding hole 232, cleaning sealing ring sleeve 31, sleeve 32, screen 33, annular airway 311, cleaning brush 3111, one-way air valve 3112 and blowing hole 3113, in the process of moving the cleaning sealing ring sleeve 31, sleeve 32 and screen 33 carrying the raw materials upward along the inner wall of the tank body 11, the internal space of the tank body 11 can be compressed to force the gas inside the tank body 11 to press the one-way air valve 3112 to open, and enter the blowing hole 3113 and the annular airway 311, and then blow toward the inner wall surface of the tank body 11 through the blowing hole 3113, so as to clean and blow dust from the inner wall of the tank body 11, thereby ensuring the cleanliness of the inner wall of the tank body 11, preventing waste and residue of raw materials, and being more conducive to improving the convenience of veterinary drug production.

[0027] Working principle: During operation, the solid raw materials of veterinary drugs to be processed are first put into the tank body 11 from the feed port 113, and then the raw materials will fall on and be stored inside the screen 33, and then the tank body 11 is closed, the cooling liquid flow interlayer 111 is connected to the liquid circulation supply equipment, and the hydraulic cylinder 21 is started. As the output rod of the hydraulic cylinder 21 is retracted, it will lift the screw rod 22 upward, and the screw rod 22 will pass through the butterfly hole plate 231 upward, and the driving tube 23 will rotate and move downward through the butterfly hole plate 231, and the spray connecting tube 25, grinding body 24, cleaning sealing ring sleeve 31, sheath 32 and screen 33 connected to the driving tube 23 will move downward with the driving tube 23, and the screen 33 will first dock and adsorb with the magnetic stripe base 112. The grinding body 24 and the spray connecting pipe 25 will continue to move downward, and because the grinding body 24 and the spray connecting pipe 25 move downward, the cleaning sealing ring sleeve 31, the sheath 32 and the screen 33 will no longer move. At this time, the cleaning sealing ring sleeve 31 will relatively pull the sliding sleeve group 34 upward by rotating the connecting frame 341, and then the sliding sleeve group 34 will drag the piston rod 343 to slide upward along the inner wall of the hydraulic gap 251. Due to the increase in the internal space of the hydraulic gap 251, a negative pressure environment will appear in the hydraulic gap 251, thereby forcing the liquid replenishment valve 3432 to open, and then the liquid stored in the liquid storage tube 233 will enter the interior of the liquid replenishment channel 3431, and enter the interior of the hydraulic gap 251 through the liquid replenishment channel 3431. When the piston rod 343 moves to the uppermost end of the sliding hole inside the spray connecting pipe 25 or the sliding sleeve group 34 moves to the uppermost side along the annular groove, the grinding body 24 and the screen 33 are in a state of being in close contact with each other at the minimum spacing distance. During this process, as the grinding body 24 gradually approaches the screen 33, when the grinding body 24 contacts the raw material inside the screen 33, the rapidly rotating grinding body 24 will cooperate with the screen 33 to rotate and grind the raw material to crush the raw material. If the resistance of the raw material is large or the grinding body 24 cannot continue to rotate and move downward, the hydraulic cylinder 21 will push down the screw rod 22 in advance, and the screw rod 22 will cooperate with the butterfly hole plate 231, and the butterfly hole through the butterfly hole plate 231 drives the driving pipe 23 to rotate and move upward along the mobile auxiliary bracket 116, and The grinding body 24 and the spray connecting pipe 25 will simultaneously rotate and move upward along with the driving pipe 23. At this time, since the screen 33 and the magnetic stripe base 112 are in a magnetic state, the cleaning sealing ring sleeve 31, the sheath 32 and the screen 33 will not move upward along with the driving pipe 23, the grinding body 24 and the spray connecting pipe 25. Then, the sliding sleeve group 34 will move downward along the annular groove on the side of the spray connecting pipe 25 under the pull of the cleaning sealing ring sleeve 31. The sliding sleeve group 34 that moves downward will gradually move out of the range of blocking the sprayer 252, thereby opening the output end of the sprayer 252. At the same time, the sliding sleeve group 34 will drag the piston rod 343 to move downward along the hydraulic gap 251. The downward movement of the piston rod 343 will compress the storage space of the hydraulic gap 251.Then, the liquid stored in the hydraulic gap 251 is forced to be sprayed into the tank body 11 through the sprayer 252. While cooling and reducing dust inside the tank body 11, the environmental humidity inside the tank body 11 can be increased to a certain extent, thereby reducing the generation of static electricity during the grinding process and reducing the risk of dust explosion. When the sliding sleeve group 34 compresses the return spring 342 and moves to the bottom along the annular groove, as the driving pipe 23 continues to move upward, the screen 33 will break through the magnetic attraction field of the magnetic stripe base 112 and quickly move upward along the inner wall of the tank body 11. Under the action of inertia and the return spring 342, the cleaning sealing ring sleeve 31, the sheath 32 and the screen 33 will reciprocate and vibrate and float with a certain amplitude, thereby screening the ground raw materials, so that the qualified raw materials pass through the strip groove body on the bottom of the screen 33 and fall into the interior of the magnetic stripe base 112. At the same time, the upward moving cleaning The sweeping sealing ring sleeve 31 will cooperate with the cleaning brush 3111 to clean the inner wall of the tank body 11, and the sweeping sealing ring sleeve 31, the sheath 32 and the screen 33 will also cooperate with the raw materials to compress the space inside the tank body 11, thereby forcing the gas inside the tank body 11 to break through the one-way air valve 3112 and enter the blowing hole 3113, and then the cleaning brush 3111 will blow on the inner wall of the tank body 11 to clean the inside of the tank body 11 with air blowing, so as to ensure the cleanliness of the inner wall of the tank body 11 and prevent the waste and residue of raw materials. Then the valve of the electric control discharge valve 114 will be opened to output the crushed raw materials. The above process will continue to be executed before the raw materials are completely crushed until the raw materials are crushed. After the crushing is completed, all structures will be reset, and then the residue can be discharged through the electric control discharge valve 114 at the bottom of the screen 33, and the liquid storage tube 233 can be replenished with water through the booster water supply pipe 115.

[0028] It should be noted that the sliding distance of the sliding sleeve group 34 and the return spring 342 can meet the requirement of the grinding body 24 moving down and contacting and crushing with the screen 33 or the raw material; the cleaning sealing ring sleeve 31, the sheath 32 and the screen 33 only slide up and down in a straight line; the sprayer 252 has an anti-reverse function or the sprayer 252 is equipped with an anti-reverse valve; the cooling liquid can be water, an auxiliary liquid for the preparation of veterinary drugs, etc., which can be selected according to needs; the humidification inside the tank body 11 is within a controllable range and will not affect the preparation of veterinary drugs; an elastic spacer is arranged on the upper surface of the side ring groove of the spray connecting pipe 25.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
