The staff pours the feed into the barrel body 1 through the feed hopper 5, and the feed entering the barrel body 1 is blocked by the screen 9 in the mounting frame 8, which is convenient for blocking the feed whose volume does not meet the requirements. The feed is crushed by the crushing knife 6 when passing through the crushing knife 6, which is conducive to reducing the volume of the feed and passing through the screen 9 to fall onto the hollow block 10, which is conducive to improving the effect of crushing the feed and avoiding the mixing of larger volume feed. The top outer circle of the hollow block 10 is high and the inner circle is low, which is convenient for guiding the crushed feed to the discharge hole at the center of the hollow block 10, so as to facilitate the discharge of the crushed feed. The motor 2 is fixed on the mounting frame 3, which is convenient for enhancing the stability of the motor 2 when working, and the top of the fixed frame 7 is inclined, which is convenient for preventing the feed from accumulating on the top of the fixed frame 7.

[0040] Embodiment 2, as Figure 1 - Figure 4 As shown, one end of the mounting frame 3 close to the rotating shaft 4 is fixedly installed on one end of the barrel body 1, the output end of the motor 2 is coaxially fixedly connected with the end of the rotating shaft 4 located outside the barrel body 1, the two mounting frames 8 are slidably installed on the outer surface of the fixing frame 7 at one end away from the inner wall of the barrel body 1, and the two ends of the fixing frame 7 away from the rotating shaft 4 are fixedly installed on the inner wall of the barrel body 1, and the rotating shaft 4 is located outside The end of the barrel body 1 is fixedly installed with a convex plate 401, and the end of the barrel body 1 close to the convex plate 401 is slidably installed with two moving blocks 101, the outer surface of the barrel body 1 away from the motor 2 is fixedly installed with a connecting pipe 102, and the outer surface of the connecting pipe 102 is fixedly installed with a plurality of connecting pipes 103, and the ends of the two moving blocks 101 close to the connecting pipe 102 are fixedly installed with a first spring 107, and the other ends of the two first springs 107 are fixedly installed on the outer surface of the connecting pipe 102.

Two through holes 109 are provided on one end of the connecting tube 102 close to the moving block 101, and a lifting rod 104 is slidably installed on one end of the multiple connecting tubes 103 located inside the barrel body 1, and a sealing ring 105 is fixedly installed on one end of the multiple connecting tubes 103 located inside the connecting tube 103, and the outer surfaces of the multiple sealing rings 105 are respectively in contact with the inner walls of the multiple connecting tubes 103, and a second spring 106 is fixedly installed on one end of the multiple connecting rods 104 located inside the connecting tube 103, and the other ends of the multiple second springs 106 are respectively fixedly installed on the inner walls of the multiple connecting tubes 103, and the ends of the multiple lifting rods 104 away from the sealing ring 105 are respectively fixedly installed on the outer surfaces of the two mounting frames 8.

[0041] In this embodiment, when in use, the rotating shaft 4 drives the convex plate 401 to rotate when it rotates, and the convex plate 401 squeezes the moving block 101 to move on the barrel body 1 when it rotates.

[0042] Working principle: When in use, the external power supply is turned on, and when the staff controls the motor 2 to work, the output end of the motor 2 drives the rotating shaft 4 to rotate inside the barrel body 1, and when the rotating shaft 4 rotates inside the fixed frame 7, it drives multiple crushing knives 6 to rotate. The staff pours the feed into the barrel body 1 through the feed hopper 5, and the feed entering the barrel body 1 is blocked by the screen 9 in the installation frame 8, which is convenient for blocking the feed that does not meet the volume requirements. When the feed passes through the crushing knife 6, it is crushed by the crushing knife 6, which is conducive to reducing the volume of the feed and passing through the screen 9 to fall onto the hollow block 10, which is conducive to improving the efficiency of crushing the feed. The outer ring of the top of the hollow block 10 is high and the inner ring is low, which is convenient for guiding the crushed feed to the discharge hole at the center of the hollow block 10, so as to facilitate the discharge of the crushed feed. The motor 2 is fixed on the mounting frame 3, which is convenient for enhancing the stability of the motor 2 when working. The top of the fixing frame 7 is inclined, which is convenient for preventing the feed from accumulating on the top of the fixing frame 7. When in use, the rotating shaft 4 rotates and drives the convex plate 401 to rotate. When the convex plate 401 rotates, it squeezes the moving block 101 to move on the barrel body 1. When the moving block 101 moves, it drives the piston block 108 to move in the connecting pipe 102. At the same time, the moving block When 101 is squeezed and moved by the convex plate 401, the first spring 107 is compressed. When the piston block 108 moves, it passes through the through hole 109 and pushes the gas inside the connecting pipe 102 into the connecting pipe 103. The gas entering the connecting pipe 103 pushes the lifting rod 104 to drive the installation frame 8 to move toward the crushing knife 6. When the installation frame 8 moves, it drives the screen 9 and the feed to move. When the lifting rod 104 moves, it drives the sealing ring 105 to move. At the same time, the lifting rod 104 will stretch the second spring 106. The setting of the sealing ring 105 is convenient for enhancing the sealing performance with the inside of the connecting pipe 103 to prevent gas leakage. When the moving block 101 is no longer squeezed, the elastic action of the first spring 107 and the second spring 106 will facilitate the moving block 101 and the lifting rod 104 to return to their original positions. When the lifting rod 104 returns to its original position, the mounting frame 8 and the screen 9 return to their original positions. As the convex plate 401 frequently rotates following the rotating shaft 4, the mounting frame 8 and the screen 9 perform frequent vertical reciprocating motions, thereby forming vibrations, which is beneficial to prevent the screen 9 from being blocked by feed, and at the same time accelerates the speed at which the crushed feed passes through the screen 9, and is beneficial to prevent the feed from adhering to the screen 9, thereby reducing the difficulty of cleaning and reducing feed waste. The model of the motor 2 is BLDC75W.
