The fixed shell 509 is fixedly connected at a position between the inner surface walls of the crushing box 101 and positioned below the connecting plate 507, a plurality of through openings 510 are formed in the top of the fixed shell 509 at equal intervals, the outer surface of the lower pressing cutter 508 is in sliding fit with the inner surface walls of the through openings 510, when the lower pressing cutter 508 moves upwards along with the connecting plate 507, the lower pressing cutter 508 can slide into the through openings 510 on the surface of the fixed shell 509 from bottom to top, and the adhered objects adhered on the surface of the lower pressing cutter 508 can be scraped off by the opening edges below the through openings 510.
When the driving motor 102 drives the first belt pulley 301 to rotate, the third belt pulley 501 can rotate along with the first belt pulley 301, the third belt pulley 501 can drive the fourth belt pulley 503 to rotate through the second driving belt 502, when the fourth belt pulley 503 rotates, the crank shaft 504 can drive the crank shaft 504 to rotate, the crank neck of the crank shaft 504 can drive the top end of the connecting rod 505 to do eccentric motion, in the process, the connecting rod 505 cooperates with the rotating seat 506 to drive the connecting plate 507 to reciprocate up and down in the crushing box 101, in the process of reciprocating up and down of the connecting plate 507, the lower pressing knife 508 not only can cut up the large pet feed above the two crushing rollers 305, but also can press down the pet feed to be tightly attached to the crushing rollers 305, thereby improved crushing effect, reduced the residence time of bulk pet feed raw materials in crushing roller 305 top, improved whole production efficiency, and, in the through-hole 510 of fixed shell 509 surface can be upwards slided from the bottom when lower pressure sword 508 follows connecting plate 507 and upwards remove, the opening edge of through-hole 510 below can strike off the adhesion thing that adheres to lower pressure sword 508 surface, simultaneously, the crushing roller 305 can be realized to the driving force that only relies on a driving motor 102 to provide in this device operation in-process, cleaning roller 310 carries out the clearance work to crushing roller 305, sieve 407 carries out the shake operation, feed back subassembly 2 carries out the feed back operation, pressing assembly 5 carries out the work of pushing down the cutting raw materials, the effect of energy-conservation has been played when effectively reducing the device cost.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
