Description

Technical Field

[0001] The present invention relates to the technical field of crushing, and particularly relates to a crushing and grinding device for veterinary drug raw materials. Background Art

[0002] Veterinary drugs are generally used for preventing, treating, and diagnosing animal diseases or purposefully regulating the physiological functions of animals. During the production of veterinary drugs, the raw materials need to be crushed for subsequent processing; the traditional way of crushing veterinary drug raw materials is done manually, but such a crushing method has a high labor intensity and low work efficiency.

[0003] To solve the problems existing in the traditional veterinary drug crushing method, a raw material grinding device for veterinary drug preparation disclosed in Chinese Patent with the publication number CN214811290U includes a bottom plate. An fixing plate is installed at the upper end of the bottom plate, and an automatic grinding mechanism is installed on the bottom plate. The grinding box is arranged above the bottom plate. One side wall of the fixing plate close to the grinding box is connected with a connecting plate, and the other end of the connecting plate is hinged to the outer box wall of the grinding box. The upper end of the bottom plate is connected with a moving pipe, and a moving rod is slidably connected in the moving pipe. The other end of the moving rod passes through the pipe orifice of the moving pipe and extends upward and is hinged to the outer bottom of the grinding box, and the moving pipe and the moving rod are connected by bolts. One side wall of the fixing plate close to the grinding box is connected with a limiting plate, and a sliding groove is opened on the side wall at the lower end of the limiting plate. A slider is slidably connected in the sliding groove; using this crushing device can replace manual labor to complete the crushing of veterinary drug raw materials, reduce the labor intensity, and improve the work efficiency.

[0004] The following problems exist during the actual use of the above-mentioned crushing device: after the raw materials are crushed to obtain raw material particles, they are collected manually, but the sizes of the raw material particles are different. It is necessary to manually screen out the raw material particles with qualified sizes, but such an operation method is very cumbersome and has low work efficiency. Summary of the Invention

[0005] The present invention aims to provide a crushing and grinding device for veterinary drug raw materials to solve the problem that the existing device does not have a screening function.

[0006] To achieve the above object, the present invention adopts the following technical solution: A crushing and grinding device for veterinary drug raw materials, comprising a processing box, which is provided with a feed inlet and a discharge outlet. A lifting plate is vertically slidably connected inside the processing box, and a plurality of crushing blocks are provided at the bottom of the lifting plate. A fixed plate and a screening mesh are provided inside the box body. A plurality of through holes are provided on the fixed plate, and the screening mesh is located below the fixed plate. A movable plate is horizontally slidably connected inside the box body. The movable plate is located above the fixed plate and is in frictional contact with the fixed plate. A plurality of screening holes are provided on the movable plate, and the screening holes are offset from the through holes and can communicate with the through holes. The crushing blocks can enter and exit the screening holes and the through holes. It further includes a driving mechanism for driving the lifting plate to reciprocate vertically and a power mechanism for driving the movable plate to reciprocate horizontally.

[0007] The principle and advantages of this solution are as follows:

[0008] 1. In this solution, the raw materials enter the processing box through the feed inlet, so that the raw materials are located between the lifting plate and the movable plate. The driving mechanism drives the lifting plate to reciprocate vertically, and the lifting plate drives the crushing blocks to reciprocate vertically, that is, the raw materials are crushed by the intermittent action of the crushing blocks to obtain raw material particles. The power mechanism drives the movable plate to reciprocate horizontally, so that the screening holes and the through holes intermittently communicate. When the two communicate, the raw material particles fall onto the screening mesh through the screening holes and the through holes, and are screened by the screening mesh. The qualified raw material particles fall to the bottom inside the processing box through the screening mesh and are then discharged from the discharge outlet. Compared with the prior art, this solution does not require manual screening, improving the work efficiency.

[0009] 2. In this solution, the screening holes and the through holes intermittently communicate. Only when the screening holes and the through holes communicate can the raw material particles pass through the screening holes and the through holes and fall onto the screening mesh. In this way, intermittent feeding can be realized, and the quantitative raw material particles can prompt the screening mesh to perform screening better.

[0010] 3. In this solution, when the screening holes and the through holes communicate, the crushing blocks can pass through the screening holes and the through holes. On the one hand, it can prevent the screening holes and the through holes from being blocked, and on the other hand, it can also squeeze the crushed raw material particles to pass through the screening holes and the through holes.

[0011] Furthermore, dividing blocks are provided on both sides inside the through holes, and the height of one dividing block is greater than that of the other dividing block.

[0012] Through the above settings, when the crushing blocks squeeze the raw material particles through the through holes, the two dividing blocks inside the through holes can further divide the raw materials, making the volume of the raw material particles smaller, which is more conducive to the screening mesh to screen the raw material particles with appropriate sizes.

[0013] Further, the driving mechanism includes a rotating shaft rotatably connected to the box body, a C-shaped block fixedly connected to the lifting plate, and a driving part for driving the rotating shaft to rotate. A first cam is coaxially connected to the rotating shaft, and the first cam abuts against both ends of the C-shaped block. The first cam can rotate within the C-shaped block.

[0014] With the above settings, the driving part drives the rotating shaft to rotate, the rotating shaft drives the first cam to rotate, the first cam drives the lifting plate to move vertically back and forth through the C-shaped block, and the lifting plate drives the crushing block to move vertically back and forth.

[0015] Further, the power mechanism includes a cylindrical cam coaxially connected to the rotating shaft and a power block slidably connected to the box body horizontally. A curve groove is provided on the cylindrical cam, one end of the power block is slidably connected to the curve groove, and the other end of the power block is fixedly connected to the movable plate.

[0016] With the above settings, during the rotation of the rotating shaft, the rotating shaft also drives the cylindrical cam to rotate. The cylindrical cam drives the power block to move horizontally back and forth through the curve groove, and the power block drives the movable plate to move horizontally back and forth.

[0017] Further, the screening mesh is arc-shaped; a round shaft is rotatably connected inside the box body, and a sector-shaped block for grinding is sleeved on the round shaft. The sector-shaped block is in frictional contact with the inner wall of the box body, and the sector-shaped block is located above the screening mesh; an adjusting block is slidably connected to the box body, one end of the adjusting block is hinged to the sector-shaped block, and the other end of the adjusting block is fixedly connected to the movable plate.

[0018] With the above settings, the raw material particles fall onto the top of the sector-shaped block, and the raw material particles can be dispersed, so that the raw material particles fall onto the screening mesh and are located on both sides of the sector-shaped block.

[0019] During the horizontal reciprocating movement of the movable plate, the movable plate drives the adjusting block to move horizontally back and forth, and the adjusting block drives the sector-shaped block to swing back and forth. The cooperation between the lowest point of the sector-shaped block and the screening mesh is used to grind the raw material particles to obtain raw material powder; the qualified-sized raw material powder passes through the screening mesh and falls to the bottom inside the box body, and finally is discharged from the discharge port, while the unqualified-sized raw material powder and raw material particles continue to stay on the screening mesh, and the cooperation between the lowest point of the sector-shaped block and the screening mesh is used to continue grinding the unqualified-sized raw material powder and raw material particles until all the raw material powder passes through the screening mesh.

[0020] Further, a chamber is provided inside the sector-shaped block, and bottom grooves are provided on both sides of the bottom of the sector-shaped block. The bottom grooves communicate with the chamber; guide plates are provided on both sides inside the chamber, a guide block is slidably connected to the guide plate, and a spring is provided between the guide block and the guide plate; an arc-shaped block is provided on the guide block, and the arc-shaped block is in frictional contact with the bottom groove; a wall groove is provided on the side wall of the sector-shaped block, and the wall groove communicates with the chamber; an arc-shaped platform is provided inside the processing box, and the arc-shaped platform passes through the wall groove and extends into the chamber. The arc-shaped platform can move relative to each other within the wall groove, and one end of the guide block away from the arc-shaped block abuts against the arc-shaped platform.

[0021] With the above settings, during the reciprocating swing of the sector block, the arc-shaped table moves relative to the wall groove; when the sector block swings to the left, the upper end of the left guide block moves to a position close to the middle of the arc-shaped table, and the upper end of the right guide block moves to a position close to the right side of the arc-shaped table. The arc-shaped table is used to squeeze the left guide block to drive the left arc-shaped block closer to the screening mesh, and the spring is compressed. Then, the cooperation between the left arc-shaped block and the screening mesh is used to grind the raw material particles, expanding the grinding range of the raw material particles and improving the grinding efficiency; the right guide block and the right arc-shaped block are in the initial position, that is, the distance between the right arc-shaped block and the screening mesh is the largest at this time, so that the raw material particles can enter between the right arc-shaped block and the screening mesh; similarly, when the sector block swings to the right, the upper end of the left guide block moves to a position close to the left side of the arc-shaped table, and the upper end of the right guide block moves to a position close to the middle of the arc-shaped table. The arc-shaped table is used to squeeze the right guide block to drive the right arc-shaped block closer to the screening mesh, and the spring is compressed. Then, the cooperation between the right arc-shaped block and the screening mesh is used to grind the raw material particles, expanding the grinding range of the raw material particles and improving the grinding efficiency; the left guide block and the left arc-shaped block are in the initial position, that is, the distance between the left arc-shaped block and the screening mesh is the largest at this time, so that the raw material particles can enter between the left arc-shaped block and the screening mesh.

[0022] Furthermore, an arc-shaped surface is provided at one end of the guide block away from the arc-shaped block, and the arc-shaped surface abuts against the arc-shaped table.

[0023] With the above settings, the arc-shaped surface is used to contact the arc-shaped table instead of the guide block, the contact surface is smaller, and the friction between the two is smaller, making the movement of the guide block smoother.

[0024] Furthermore, vertical holes are provided on both sides of the top of the screening mesh, and elastic layers are provided in the vertical holes; both sides in the box body are rotatably connected with side shafts, the side shafts are located below the screening mesh, and gears and second cams for squeezing the elastic layers are coaxially connected to the side shafts; both sides of the box body are horizontally slidably connected with racks, a linkage block is directly fixed between the rack and the movable plate, and the rack meshes with the gear.

[0025] With the above settings, during the horizontal reciprocating movement of the movable plate, the movable plate drives the rack to reciprocate horizontally through the linkage block; when the sector block swings to the left, the two racks move to the left; the left rack meshes with the left gear to drive the left gear to rotate, and the left gear drives the left second cam to rotate through the left side shaft. The convex part of the left second cam is used to squeeze the left elastic layer to bulge upward, making the left bulge close to the left arc-shaped block, which is beneficial to the grinding treatment of the raw material particles and strengthens the grinding effect; the right rack meshes with the right gear to drive the right gear to rotate, and the right gear drives the right second cam to rotate through the right side shaft, so that the convex part of the right second cam is away from the right elastic layer.

[0037] The fan-shaped block 40 is provided with a chamber 50 inside. Bottom grooves are formed on both sides of the bottom of the fan-shaped block 40, and the bottom grooves communicate with the chamber 50. Guide plates are fixedly connected to both sides inside the chamber 50.

A linkage block 64 is directly fixedly connected between the rack bar 63 and the movable plate 25. The rack bar 63 meshes with the gear 61.

[0039] The specific implementation process is as follows:

[0040] During use, the raw materials are put into the box body through the feed port 11, so that the raw materials are located between the lifting plate 20 and the movable plate 25.

[0041] The motor 33 is started. The output shaft of the motor 33 drives the rotating shaft 30 to rotate. The rotating shaft 30 drives the first cam 32 to rotate. The first cam 32 drives the lifting plate 20 to perform vertical reciprocating motion through the C-shaped block 31. The lifting plate 20 drives the crushing block 21 to perform vertical reciprocating motion. That is, the raw materials are intermittently acted on by the crushing block 21 to realize the crushing treatment of the raw materials, and raw material particles are obtained.

[0042] During the rotation of the rotating shaft 30, the rotating shaft 30 also drives the cylindrical cam 35 to rotate. The cylindrical cam 35 drives the power block 36 to move horizontally back and forth through the curved groove. The power block 36 drives the movable plate 25 to move horizontally back and forth, so that the screening holes 26 and the through holes 24 are intermittently communicated. When the screening holes 26 are communicated with the through holes 24, the raw material particles pass through the screening holes 26 and the through holes 24 and fall downward, thereby realizing intermittent feeding. Moreover, when the screening holes 26 are communicated with the through holes 24, the crushing block 21 can pass through the screening holes 26 and the through holes 24. On the one hand, it can prevent the screening holes 26 and the through holes 24 from being blocked, and on the other hand, it can also squeeze the crushed raw material particles to pass through the screening holes 26 and the through holes 24. In addition, when the crushing block 21 squeezes the raw material particles to pass through the through hole 24, the two dividing blocks 27 in the through hole 24 can further divide the raw material, making the volume of the raw material particles smaller for subsequent grinding treatment.

[0043] The raw material particles fall onto the top of the sector block 40, which can disperse the raw material particles so that the raw material particles fall onto the screening mesh 23 and are located on both sides of the sector block 40.

[0044] During the horizontal reciprocating movement of the movable plate 25, the movable plate 25 drives the adjusting block 41 to move horizontally back and forth. The adjusting block 41 drives the sector block 40 to swing reciprocally. The cooperation between the lowest point of the sector block 40 and the screening mesh 23 is used to grind the raw material particles to obtain raw material powder. The qualified raw material powder passes through the screening mesh 23 and falls on the bottom of the box body, and finally is discharged from the discharge port 12. The unqualified raw material powder and raw material particles continue to stay on the screen, and the cooperation between the lowest point of the sector block 40 and the screening mesh 23 is used to continue grinding the unqualified raw material powder and raw material particles until all the raw material powder passes through the screening mesh 23.

[0045] During the reciprocating swing of the sector block 40, the arc-shaped table 54 moves relatively in the wall groove without affecting the swing of the sector block 40. When the sector block 40 swings to the left, the upper end of the left guide block 51 moves to a position close to the middle of the arc-shaped table 54, and the upper end of the right guide block 51 moves to a position close to the right side of the arc-shaped table 54. The arc-shaped table 54 is used to squeeze the left guide block 51 to drive the left arc-shaped block 53 to approach the screening mesh 23, and the spring 52 is compressed. Then, the cooperation between the left arc-shaped block 53 and the screening mesh 23 is used to grind the raw material particles, expanding the grinding range of the raw material particles and improving the grinding efficiency. The right guide block 51 and the right arc-shaped block 53 are in the initial position, that is, the distance between the right arc-shaped block 53 and the screening mesh 23 is the largest at this time, so that the raw material particles can enter between the right arc-shaped block 53 and the screening mesh 23. Similarly, when the sector block 40 swings to the right, the upper end of the left guide block 51 moves to a position close to the left side of the arc-shaped table 54, and the upper end of the right guide block 51 moves to a position close to the middle of the arc-shaped table 54. The arc-shaped table 54 is used to squeeze the right guide block 51 to drive the right arc-shaped block 53 to approach the screening mesh 23, and the spring 52 is compressed. Then, the cooperation between the right arc-shaped block 53 and the screening mesh 23 is used to grind the raw material particles, expanding the grinding range of the raw material particles and improving the grinding efficiency. The left guide block 51 and the left arc-shaped block 53 are in the initial position, that is, the distance between the left arc-shaped block 53 and the screening mesh 23 is the largest at this time, so that the raw material particles can enter between the left arc-shaped block 53 and the screening mesh 23.

[0046] During the horizontal reciprocating movement of the movable plate 25, the movable plate 25 drives the rack 63 to move horizontally through the linkage block 64. When the sector block 40 swings to the left, the two racks 63 move to the left. The left rack 63 meshes with the left gear 61 to drive the left gear 61 to rotate. The left gear 61 drives the left second cam 62 to rotate through the left side shaft. The convex part of the left second cam 62 is used to squeeze the left elastic layer 60 to bulge upward, so that the left bulge approaches the left arc-shaped block 53, which is beneficial to the grinding treatment of the raw material particles and strengthens the grinding effect. The right rack 63 meshes with the right gear 61 to drive the right gear 61 to rotate. The right gear 61 drives the right second cam 62 to rotate through the right side shaft, so that the convex part of the right second cam 62 moves away from the right elastic layer 60.

[0047] When the sector block 40 swings to the right, the two racks 63 move to the right; the right rack 63 meshes with the right gear 61 to drive the right gear 61 to rotate. The right gear 61 drives the right second cam 62 to rotate through the right side shaft. The convex part of the right second cam 62 is used to squeeze the right elastic layer 60 to bulge upward, so that the right bulge approaches the right arc-shaped block 53, which is beneficial to the grinding treatment of raw material particles and enhances the grinding effect; the left rack 63 meshes with the left gear 61 to drive the left gear 61 to rotate. The left gear 61 drives the left second cam 62 to rotate through the left side shaft, so that the convex part of the left second cam 62 moves away from the left elastic layer 60.

[0048] In this embodiment, an arc surface is provided at one end of the guide block 51 away from the arc-shaped block 53, and the arc surface abuts against the arc-shaped table 54; using the arc surface to replace the contact between the guide block 51 and the arc-shaped table 54, the contact surface is smaller, and the friction between the two is smaller, making the movement of the guide block 51 smoother.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
