[0028] As Figures 2-6 shown, a positioning plate 505 is fixedly connected to the arc surface of the support rod 502, the positioning plate 505 is slidably connected to the screening plate 503, two guide plates 506 are fixedly connected to the surface of the crushing box 1, the size of the guide plate 506 is adapted to the size of the screening plate 503, a fixed plate 507 is fixedly connected to the outer wall of the crushing box 1, an insert rod 508 is slidably connected in the fixed plate 507, the insert rod 508 penetrates through the connecting plate, a sphere 509 is fixedly connected to the upper end of the insert rod 508, the diameter of the sphere 509 is larger than the diameter of the insert rod 508, a reciprocating lead screw 510 is rotatably connected in the crushing box 1, two transmission frames 511 are threadedly connected to the arc surface of the reciprocating lead screw 510, a pressing roller 512 is rotatably connected to the arc surface of the transmission frame 511, the arc surface of the pressing roller 512 abuts against the upper surface of the screening plate 503, and a slide hole 513 is opened on the surface of the hopper 6.

[0029] As Figures 2-7As shown, the inner wall of the sliding hole 513 is slidably connected to the transmission frame 511. A baffle 514 is rotatably connected to the surface of the transmission frame 511. The size of the baffle 514 is larger than that of the sliding hole 513. An extension ring 515 is fixedly connected to the arc surface of the reciprocating lead screw 510. A groove is formed on the surface of the transmission frame 511, and the size of the extension ring 515 is adapted to the size of the groove. A brush rod 516 is fixedly connected to the inner wall of the crushing box 1, and the brush rod 516 abuts against the arc surface of the crushing roller 2.

[0030] Working principle: When it is necessary to crush the raw materials of pig feed, first use the pull plate 504 to slide the screening plate 503 along the inner wall of the through hole 501. During this process, by sliding the screening plate 503 along the inner wall of the guiding plate 506, it is convenient to slide the screening plate 503 into the through hole 501. The screening plate 503 will slide to the arc surface of the support rod 502 and contact the hopper 6. The support rod 502 plays a role in supporting the screening plate 503. At this time, the screening plate 503 will also contact the positioning plate 505, and the positioning plate 505 plays a role in further restricting the position of the screening plate 503. Then insert the insertion rod 508 into the pull plate 504 along the fixed plate 507. The insertion rod 508 plays a role in restricting the position of the pull plate 504, thereby restricting the position of the screening plate 503. The spherical ball 509 plays a role in preventing the insertion rod 508 from slipping out of the fixed plate 507. Pour the raw materials of pig feed into the crushing box 1, and then start the motor 3. The rotation of the output end of the motor 3 will drive the belt 4 to run. The belt 4 will drive the two crushing rollers 2 to rotate in opposite directions. The rotation of the crushing rollers 2 will crush the raw materials of pig feed. Then the raw materials of pig feed will fall into the hopper 6 and slide along the inner wall of the hopper 6 to the surface of the screening plate 503. The screening plate 503 will screen the raw materials of pig feed. At this time, the larger-volume raw materials of pig feed cannot be directly discharged, thus preventing the situation that the larger-volume raw materials of pig feed affect the quality of pig feed. During the operation of the belt 4, the belt 4 will drive the reciprocating lead screw 510 to rotate. The reciprocating lead screw 510 will drive the transmission frame 511 to move along the inner wall of the sliding hole 513 by means of the thread. By making the transmission frame 511 move along the inner wall of the sliding hole 513, the movement path of the transmission frame 511 can be restricted by the sliding hole 513, preventing the transmission frame 511 from rotating following the reciprocating lead screw 510. The movement of the transmission frame 511 will drive the pressure roller 512 to roll along the surface of the screening plate 503, thereby crushing the larger-volume raw material particles on the screening plate 503 and avoiding the situation that the larger-volume raw material particles block the screening plate 503. When the pressure roller 512 moves to a certain position, without changing the rotation direction of the reciprocating lead screw 510, the reciprocating lead screw 510 can drive the transmission frame 511 to move in the opposite direction, so that the transmission frame 511 can drive the pressure roller 512 to move reciprocally in the horizontal direction. During this process, the extension ring 515 can ensure that the two transmission frames 511 operate reciprocally normally without interfering with each other. The movement of the transmission frame 511 will drive the baffle 514 to slide along the outer wall of the hopper 6. The baffle 514 can block the sliding hole 513, preventing the feed particles from slipping through the sliding hole 513. During the rotation of the crushing roller 2, the brush rod 516 will continuously brush the arc surface of the crushing roller 2, enabling the crushing roller 2 to normally crush the feed raw materials and improving the crushing effect of the crushing roller 2.
