[0020] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0021] 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 with a square feeding pipe 1011, a partition 103 is fixed on one side of the inside of the screening box 1, and an inclined screen 2 is arranged below the square feeding pipe 1011, a crushing motor 3 is screwed on the top end of the crushing barrel 101, and the output end of the crushing motor 3 passes through the top wall flange of the crushing barrel 101 and is connected with a crushing rod 301, and multiple groups of crushing knives 302 are evenly installed on the outer wall of the crushing rod 301, and side panels 104 are arranged on both sides of the inclined screen 2, and the outer walls of the two side panels 104 are respectively fixedly connected with the outer wall of the partition 103 and the inner wall of the screening box 1, and a pull-out collecting box 102 is arranged on the inner bottom of the screening box 1 below the inclined screen 2; Side panels 104 are provided on both sides of the inclined screen 2 inside the screening box 1, and 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. Through openings are provided on the outer wall of the screening box 1 located at the inclined screen 2 and the two side panels 104, and a slide groove 1041 is provided at the bottom of one side of the two side panels 104 close to the inclined screen 2, and sliders 201 are slidably provided in the two slide grooves 1041, and the upper surfaces of the two sliders 201 extending out of the slide grooves 1041 are fixedly connected to the inclined screen 2 through a plurality of connecting rods 202, and the lower end of the inclined screen 2 and the ends of the two sliders 201 are fixedly connected with sealing plates 203 through the through openings; 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.

[0022] After the staff moves the screening box 1 to the veterinary drug crushing position, the crushing motor 3 is started 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 blanking assembly 5 through the controller, so that the channel of the square blanking pipe 1011 is opened. The veterinary drug powder falls into the inclined sieve mesh 2 under the action of gravity. At this time, the actuator of the scraping assembly 6 (the scraping plate 601 in the text) and the actuator of the blanking assembly 5 (the baffle 501) move in the opposite direction. The actuator of the scraping assembly 6 will be blocked by the inner wall of the screening box 1; After the channel of the square blanking pipe 1011 is opened for a while, the blanking assembly 5 is closed. At this time, the actuator scraping plate 601 of the scraping assembly 6 moves. After the channel of the square blanking pipe 1011 is closed, the drive source (drive motor 507) of the blanking assembly 5 continues to work, controlling the scraping plate 601 to continue moving. The moving scraping plate 601 spreads the falling veterinary drug powder evenly on the inclined sieve mesh 2, preventing the local accumulation of veterinary drug powder and ensuring that each area of the sieve mesh can be effectively screened. And the vibration provided by the vibration assembly 7 can promote the powder to pass through the inclined sieve mesh 2, further reducing the residence time of the veterinary drug powder on the sieve mesh, avoiding blockage, and prompting the veterinary drug 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 drug, effectively avoiding the accumulation of veterinary drug powder due to excessive blanking, reducing the load of the inclined sieve mesh 2, and the closing of the channel of the square blanking pipe 1011 can ensure the thorough crushing and uniform mixing of the remaining veterinary drugs; 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.

[0023] 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 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 penetrates 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 baffle plate 501. The baffle 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 baffle plate 501, side ears 502 are welded. On the side of the two side ears 502 away from the partition plate 103, a pull rod 5021 is fixed. The ends of the two pull rods 5021 are fixedly connected to a baffle plate 503. On the side of the baffle plate 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 plate 503.

[0024] 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 baffle plate 501 to slide in the square blanking pipe 1011, adjusting the channel opening to open the square blanking pipe 1011. At the same time, during the movement of the baffle plate 501, the two side ears 502 will drive the baffle plate 503 to move synchronously through the pull rod 5021 until the baffle plate 503 contacts the outer wall of the square blanking pipe 1011 to limit the movement stroke of the baffle plate 501. When the baffle plate 503 moves, it will stretch the expansion rod 5081 to further ensure the stability of the baffle plate 503 through the expansion rod 5081.

[0025] 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 arranged above the scraper 601, and both ends of the cross bar 603 are welded with fixed blocks 6031, and the two fixed blocks 6031 are penetrated with vertical rods 602, and the bottom ends of the two vertical rods 602 are fixedly connected to the upper surface of the scraper 601 at both ends, and the two ends of the upper surface of the cross bar 603 are welded with movable plates 604, and the two movable plates 604 are respectively penetrated with guide rods 605 and threaded rods 606, and one end of the threaded rod 606 is fixedly connected with 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, and 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 on the output end of the motor 507 and the transmission shaft 609, and the two transmission wheels 607 are connected by a transmission chain 6071. A limit plate 6021 is fixed on the top of the two vertical rods 602. A tension spring 6022 is arranged 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. A movable plate 604 is threadedly engaged with the contact portion of the outer wall of the threaded rod 606, and the other movable plate 604 is slidably connected with 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. The vibration assembly 7 includes multiple balls 701 and pneumatic vibration rods 702. The multiple balls 701 and the 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.

[0026] The output end of the driving motor 507 rotates to control the movement of the blocking plate 501, so that when the square feeding 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 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, and at this time, the scraper 601 will be resisted by the inner wall of the screening box 1 to restrict its movement, thereby ensuring that when the blocking plate 501 opens the square feeding tube 1011, the scraper 601 is in place and does not move (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; When the driving motor 507 works in the reverse direction to control the baffle plate 501 to reset, that is, 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 moving 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 of the scraper 601, the scraper 601 moves upward following the inclination angle of the inclined screen 2. The upwardly moving scraper 601 pushes the vertical rod 602 to move upward, and the vertical rod 602 exerts a tension force on the tension 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 spreads the fallen veterinary powder evenly 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, which act 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.

[0027] The working principle of the present invention is: 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, and 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 drug raw material is added from the feed port of the crushing barrel 101. The veterinary drug 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 driving motor 507 through the controller. The output end of the driving motor 507 drives the first magnetic coupler 506 to drive the first magnetic coupler 506. 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 feeding tube 1011, and adjusts the channel opening so that the square feeding 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 feeding tube 1011, thereby limiting the movement stroke of the blocking plate 501; The output end of the driving motor 507 also drives the transmission shaft 609 to rotate through the transmission wheel 607 and the transmission chain 6071. The transmission 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 resisted by the inner wall of the screening box 1 to restrict its movement, thereby ensuring that when the blocking plate 501 opens the square feeding pipe 1011, the scraper 601 is in place and does not move (i.e., at the lower end of the inclined screen 2); 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.
