[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0029] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0030] Please refer to Figures 1 - 5As shown, a livestock and veterinary drug crushing and screening device comprises a screening box 1 and an internal processing mechanism 4 for controlling the material dropping speed and screening. A crushing barrel 101 is installed on the top of the screening box 1, and the bottom end of the crushing barrel 101 is connected to a square discharge pipe 1011. A partition 103 is fixed to one side of the interior of the screening box 1, and an inclined screen 2 is provided below the square discharge pipe 101. A crushing motor 3 is screwed to the top of the crushing barrel 101, and the output ends of the crushing motor 3 are all connected to the crushing rod 301 with a flange through the top wall of the crushing barrel 101. Multiple groups of crushing knives 302 are evenly installed on the outer wall of the crushing rod 301. Side panels 104 are provided on both sides of the inclined screen 2. The outer walls of the two side panels 104 are fixedly connected to the outer wall of the partition 103 and the inner wall of the screening box 1 respectively. A pull-out collecting box 102 is provided at the inner bottom of the screening box 1 below the inclined screen 2.

[0031] The interior of the screening box 1 is provided with side panels 104 on both sides of the inclined screen 2. The outer walls of the two side panels 104 are fixedly connected to the outer wall of the partition 103 and the inner wall of the screening box 1 respectively. The two side walls of the inclined screen 2 are in contact with the outer walls of the side panels 104 and are slidably connected. The outer wall of the screening box 1 is provided with through openings at the inclined screen 2 and the two side panels 104. The bottom of the two side panels 104 close to the inclined screen 2 is provided with a chute 1041. Sliders 201 are slidably provided in the two chute 1041. The upper surfaces of the two slides 201 extending out of the chute 1041 are fixedly connected to the inclined screen 2 through a plurality of connecting rods 202. The lower end of the inclined screen 2 and the ends of the two slides 201 are fixedly connected with a sealing plate 203 through the through opening.

[0032] The processing mechanism 4 is composed of a blanking component 5, a scraping component 6 and a vibration component 7. The blanking component 5 is arranged on the square blanking tube 1011, and the scraping component 6 is arranged above the inclined screen 2. The scraping component 6 is transmission-connected to the blanking component 5. The blanking component 5 is used to control the opening and closing of the square blanking tube 1011 to limit the blanking speed. The scraping component 6 is used to spread the fallen veterinary drug powder evenly. The vibration component 7 is used to provide vibration to promote the powder to pass through the inclined screen 2. A controller is installed on the outer wall of the screening box 1, and a power supply 105 is installed on the bottom of the screening box 1 on the side of the partition 103 away from the collecting box 102. The power supply 105 is electrically connected to the processing mechanism 4, the controller and the crushing motor 3 through wires.

[0033] After the staff moves the screening box 1 to the veterinary medicine crushing position, the crushing motor 3 is started through the controller. The crushing motor 3 drives the crushing knife 302 to rotate at a high speed through the crushing rod 301. At this time, the veterinary medicine raw material is added from the feed port of the crushing barrel 101. The veterinary medicine raw material is quickly crushed under the action of the crushing knife 302. The crushed powder accumulates at the bottom of the crushing barrel 101. Then the staff starts the blanking component 5 through the controller, so that the passage of the square blanking pipe 1011 is opened. The veterinary medicine powder falls into the inclined sieve mesh 2 under the action of gravity. At this time, the actuator of the scraping component 6 (the scraping plate 601 in the text) and the actuator of the blanking component 5 (the blocking plate 501) move in the opposite direction. The actuator of the scraping component 6 will be blocked by the inner wall of the screening box 1;

[0034] After the passage of the square blanking pipe 1011 is opened for a while, the blanking component 5 is closed. At this time, the actuator scraping plate 601 of the scraping component 6 moves. After the passage of the square blanking pipe 1011 is closed, the drive source (drive motor 507) of the blanking component 5 continues to work, controlling the scraping plate 601 to continue moving. The moving scraping plate 601 evenly spreads the falling veterinary medicine powder on the inclined sieve mesh 2, preventing the local accumulation of veterinary medicine powder, ensuring that each area of the sieve mesh can be effectively screened, and the vibration provided by the vibration component 7 can promote the powder to pass through the inclined sieve mesh 2, further reducing the residence time of the veterinary medicine powder on the sieve mesh, avoiding blockage, and prompting the veterinary medicine powder to smoothly pass through the mesh holes of the inclined sieve mesh 2 and fall into the collection box 102, so as to realize the control of the blanking amount of the crushed veterinary medicine, effectively avoiding the accumulation of veterinary medicine powder due to excessive blanking, reducing the load of the inclined sieve mesh 2, and the closing of the passage of the square blanking pipe 1011 can ensure the thorough crushing and uniform mixing of the remaining veterinary medicine;

[0035] Among them, the inclined sieve mesh 2 can be pulled out through the sealing plate 203 for cleaning. After cleaning, the slider 201 is aligned with the sliding grooves 1041 of the two side plates 104 again and inserted, and the inclined sieve mesh 2 is pushed back into the screening box 1.

[0036] Please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown in the figure, the blanking assembly 5 includes a driving motor 507 fixed to the inner side wall of the screening box 1 by screws. The output end of the driving motor 507 is connected to a shaft rod 505 through a first magnetic coupler 506. The shaft rod 505 passes through the partition plate 103 and is connected to a lead screw 5051. The end of the lead screw 5051 is rotatably connected to the outer wall of the square blanking pipe 1011. A movable plate 504 is installed on the lead screw 5051. The top of the movable plate 504 is welded with a horizontal blocking plate 501. The blocking plate 501 is inserted into the square blanking pipe 1011 and is slidably connected to the inner wall. At both ends of the two side walls of the blocking plate 501, side ears 502 are welded. On the side of the two side ears 502 away from the partition plate 103, pull rods 5021 are fixed. The ends of the two pull rods 5021 are fixedly connected to a baffle 503. On the side of the baffle 503 away from the square blanking pipe 1011, a mounting plate 508 is provided. The top of the mounting plate 508 is fixed to the inner top wall of the screening box 1 by screws. An expansion rod 5081 is installed on the mounting plate 508 by screws. The telescopic end of the expansion rod 5081 is fixedly connected to the baffle 503.

[0037] When blanking, the controller starts the driving motor 507. The output end of the driving motor 507 drives the shaft rod 505 to rotate through the first magnetic coupler 506. The shaft rod 505 drives the lead screw 5051 to rotate, so that the movable plate 504 moves along the lead screw 5051 and drives the blocking plate 501 to slide in the square blanking pipe 1011, adjusting the opening of the channel, so that the square blanking pipe 1011 is opened. At the same time, during the movement of the blocking plate 501, the two side ears 502 will drive the baffle 503 to move synchronously through the pull rods 5021 until the baffle 503 contacts the outer wall of the square blanking pipe 1011, limiting the movement stroke of the blocking plate 501. When the baffle 503 moves, it will stretch the expansion rod 5081, further ensuring the stability of the baffle 503 through the expansion rod 5081.

[0038] Please refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7As shown, the scraper assembly 6 includes a scraper 601 arranged on the upper surface of the inclined screen 2, a cross bar 603 is provided above the scraper 601, and fixed blocks 6031 are welded at both ends of the cross bar 603, and vertical rods 602 are penetrated on the two fixed blocks 6031, and the bottom ends of the two vertical rods 602 are fixedly connected to both sides of the upper surface of the scraper 601, and movable plates 604 are welded on both ends of the upper surface of the cross bar 603, and guide rods 605 and threaded rods 606 are penetrated in the two movable plates 604, respectively. One end of the threaded rod 606 is fixedly connected to a rotating shaft 6061, and the rotating shaft 6061 passes through the partition 103 and is connected to a transmission shaft 609 through a second magnetic coupler 608. The other end of the transmission shaft 609 is rotatably connected to the inner wall of the screening box 1, driving A transmission wheel 607 is fixed to the output end of the motor 507 and the transmission shaft 609. The two transmission wheels 607 are connected by a transmission chain 6071. A limit plate 6021 is fixed to the top of the two vertical rods 602. A tension spring 6022 is provided between each limit plate 6021 and the fixed block 6031. Each tension spring 6022 is sleeved on the vertical rod 602. The two ends of the guide rod 605 are respectively fixedly connected to the inner wall of the screening box 1 and the outer wall of the partition 103. One movable plate 604 is threadedly engaged with the contact portion of the outer wall of the threaded rod 606. The other movable plate 604 is slidably connected to the contact portion of the outer wall of the guide rod 605. The end of the threaded rod 606 away from the rotating shaft 6061 is rotatably connected to the inner wall of the screening box 1.

[0039] The vibration assembly 7 includes multiple balls 701 and pneumatic vibration rods 702. The multiple balls 701 and pneumatic vibration rods 702 are evenly embedded in the lower surface of the scraper 601 set in the scraper assembly 6. The multiple balls 701 and the pneumatic vibration rods 702 are staggered. The telescopic ends of the multiple pneumatic vibration rods 702 are all equipped with vibration balls 7021. The outer walls of each ball 701 and vibration ball 7021 are in contact with the upper surface of the inclined screen 2.

[0040] The output end of the driving motor 507 rotates to control the movement of the baffle plate 501, so that when the square discharge tube 1011 is opened, the output end of the driving motor 507 will drive the transmission shaft 609 to rotate through the transmission wheel 607 and the transmission chain 6071, and the transmission shaft 609 drives the rotating shaft 6061 to rotate through the second magnetic coupling 608, thereby driving the threaded rod 606 to rotate, so that the movable plate 604 on the threaded rod 606 moves axially under the restriction of the cross bar 603 and the guide rod 605, and at this time the scraper 601 will be pressed against the inner wall of the screening box 1 to restrict its movement, thereby ensuring that when the baffle plate 501 opens the square discharge tube 1011, the scraper 601 remains in place (i.e., at the lower end of the inclined screen 2), and at this time the scraper 601 is in contact with the inclined screen 2 under the action of the tension spring 6022;

[0041] When the driving motor 507 works in the reverse direction to control the baffle plate 501 to reset, that is, when the square feeding tube 1011 is closed, the transmission shaft 609 rotates in the reverse direction, driving the rotating shaft 6061 and the threaded rod 606 to reverse, and the movable plate 604 moves in the reverse direction, controlling the scraper 601 to move toward the high end of the inclined screen 2. During the movement, the scraper 601 will move upward following the inclination angle of the inclined screen 2. The upward moving scraper 601 will push the vertical rod 602 to move upward, and the vertical rod 602 will tension the spring 6022 through the limit plate 6021. The stretching spring 6022 stores elastic potential energy to ensure that the ball 701 at the bottom of the scraper 601 fits tightly with the inclined screen 2. The moving scraper 601 evenly spreads the fallen veterinary powder on the inclined screen 2 to prevent local accumulation of veterinary powder and ensure that each area of the screen can be effectively screened. At the same time, multiple pneumatic vibration rods 702 work to generate high-frequency vibrations through the vibrating balls 7021, acting on the inclined screen 2 to promote the powder to pass through the inclined screen 2, further reducing the residence time of the veterinary powder on the screen and avoiding blockage.

[0042] The working principle of the present invention is:

[0043] After the staff moves the screening box 1 to the veterinary drug crushing processing position, the staff starts the crushing motor 3 through the controller. The crushing motor 3 drives the crushing knife 302 to rotate at high speed through the crushing rod 301. At this time, the veterinary drug raw materials are added from the feed port of the crushing barrel 101. The veterinary drug raw materials are quickly crushed under the action of the crushing knife 302. The crushed powder accumulates at the bottom of the crushing barrel 101. Then the staff starts the driving motor 507 through the controller. The output end of the driving motor 507 drives the first magnetic coupler 506 to rotate. The shaft 505 rotates, and the shaft 505 drives the screw 5051 to rotate, so that the movable plate 504 moves along the screw 5051, and drives the blocking plate 501 to slide in the square discharge tube 1011, adjusting the channel opening so that the square discharge tube 1011 is opened. At the same time, during the movement of the blocking plate 501, the two side ears 502 will drive the baffle 503 to move synchronously through the pull rod 5021 until the baffle 503 contacts the outer wall of the square discharge tube 1011, thereby limiting the movement stroke of the blocking plate 501;

[0044] The output end of the drive motor 507 also drives the drive shaft 609 to rotate through the transmission wheel 607 and the transmission chain 6071. The drive shaft 609 drives the rotating shaft 6061 to rotate through the second magnetic coupler 608, thereby driving the threaded rod 606 to rotate, so that the movable plate 604 on the threaded rod 606 moves axially under the restriction of the cross bar 603 and the guide rod 605. At this time, the scraper 601 will be supported by the inner wall of the screening box 1, limiting its movement, thereby ensuring that when the blocking plate 501 opens the square discharge pipe 1011, the scraper 601 remains in place (i.e., at the lower end of the inclined screen 2).

[0045] After the passage of the square blanking pipe 1011 is opened for a while, the drive motor 507 operates in the reverse direction to control the reset of the baffle plate 501, closing the square blanking pipe 1011. The transmission shaft 609 rotates in the reverse direction, driving the rotating shaft 6061 and the threaded rod 606 to reverse. The moving plate 604 moves reversely accordingly, controlling the scraper 601 to move towards the high end of the inclined screen 2. During the movement of the scraper 601, the scraper 601 will move upward following the inclination angle of the inclined screen 2. The upward-moving scraper 601 will push the vertical rod 602 upward. The vertical rod 602 stretches the tension spring 6022 through the limit plate 6021, and the tension spring 6022 stores elastic potential energy to ensure that the ball 701 at the bottom of the scraper 601 is in close contact with the inclined screen 2. The moving scraper 601 evenly spreads the falling veterinary medicine powder on the inclined screen 2, preventing local accumulation of the veterinary medicine powder and ensuring that each area of the screen can be effectively screened. At the same time, multiple pneumatic vibrating rods 702 work, generating high-frequency vibrations through the vibrating balls 7021 and acting on the inclined screen 2 to promote the powder to pass through the mesh holes of the inclined screen 2 and fall into the collection box 102. Finally, the collection box 102 is pulled out, and the screened veterinary medicine powder is taken out to complete the entire screening process.

[0046] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
