When the first pulley 205 rotates, it can drive the rotating roller 202 connected to it to rotate. When the device is running, when the other first gear 306 rotates, it will drive the third pulley 307 connected to it to rotate. When the third pulley 307 rotates, it will drive the fourth pulley 308 to rotate through the second transmission belt 309.

[0030] The second rotating shaft 406 is fixedly connected between the front and rear inner walls of the first opening 106, and the outer surface of the second rotating shaft 406 is rotatably connected with an inclined screen plate 407. The first rotating shaft 404 is rotatably connected between the front and rear inner walls of the crushing box 101 and below the screen plate 407. The rear end of the first rotating shaft 404 is fixedly connected with a sixth pulley 403. The outer surface of the sixth pulley 403 is sleeved with a third transmission belt 402 extending upward. The inner surface wall of the third transmission belt 402 is near the upper position for transmission connection.

The fourth pulley 503 drives the crankshaft 504 to rotate. When the crankshaft 504 rotates, the curved neck of the crankshaft 504 drives the top of the connecting rod 505 to make eccentric movement. During the process, the connecting rod 505 cooperates with the rotating seat 506 to drive the connecting plate 507 to reciprocate up and down. The downward pressing knife 508 under the connecting plate 507 can not only chop up the large pieces of pet feed above the two crushing rollers 305, but also presses down the pet feed to make it fit more closely with the crushing roller 305, thereby improving the crushing effect.

[0035] The fixed shell 509 is fixedly connected between the inner walls of the crushing box 101 and below the connecting plate 507. A plurality of through openings 510 are equidistantly provided on the top of the fixed shell 509. The outer surface of the lower pressing knife 508 and the inner wall of the through opening 510 are slidably fitted. When the lower pressing knife 508 moves upward following the connecting plate 507, it will slide from bottom to top into the through opening 510 on the surface of the fixed shell 509. The opening edge below the through opening 510 can scrape off the adhesion adhered to the surface of the lower pressing knife 508.

[0036] The use steps of the present invention are as follows: when the driving motor 102 drives the first pulley 301 to rotate, the third pulley 501 will rotate accordingly, and the third pulley 501 will drive the fourth pulley 503 to rotate through the second transmission belt 502. When the fourth pulley 503 rotates, it will drive the crankshaft 504 to rotate. When the crankshaft 504 rotates, the curved neck of the crankshaft 504 will drive the top of the connecting rod 505 to make an eccentric movement. During this process, the connecting rod 505 cooperates with the rotating seat 506 to drive the connecting plate 507 to reciprocate up and down inside the crushing box 101. During the up and down reciprocating movement of the connecting plate 507, the lower pressing knife 508 below can not only chop up the large pieces of pet food above the two crushing rollers 305, but also press the pet food down to make it fit more closely with the crushing rollers 305. The tight action improves the crushing effect, reduces the retention time of large pieces of pet feed raw materials above the crushing roller 305, and improves the overall production efficiency. In addition, when the lower pressing knife 508 moves upward following the connecting plate 507, it will slide from bottom to top into the through hole 510 on the surface of the fixed shell 509, and the opening edge below the through hole 510 can scrape off the adhesion on the surface of the lower pressing knife 508. At the same time, during the operation of the device, the crushing roller 305 can be crushed by relying on the driving force provided by a driving motor 102, the cleaning roller 310 can clean the crushing roller 305, the screen plate 407 can be shaken, the return material component 2 can be returned, and the pressing component 5 can press down and cut the raw materials, which effectively reduces the cost of the device and plays an energy-saving role.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
