This method significantly increases the density and hardness of the feed, while prolonging the chewing time and eating process of the animal, thus helping to improve the digestion and absorption rate of the feed.

[0003] In actual applications, it is found that the raw materials for the production of biological feed usually include various natural organic substances, plant raw materials, animal by-products and microbial fermentation products. Among them, grains, soybean meal, rice husks, etc. have high hardness and long-term use may cause increased wear on the surface of rollers and molds.

[0060] Please refer to Figure 3 , Figure 6 and Fig. 9A crushing mechanism 4 is arranged on the protection mechanism 3, and the crushing mechanism 4 includes a mounting shell 401, the mounting shell 401 is threadedly connected to the upper end of the transmission shaft 305, a first nut 402 is fixed to the top surface of the mounting shell 401, evenly distributed blades 403 are fixed to the side of the mounting shell 401, a vibration assembly 405 is fixed to the lower end of the mounting shell 401, and a filter screen 404 is fixed on the vibration assembly 405.

[0061] The vibration component 405 includes a fixing ring 4051 fixed to the lower end of the mounting shell 401, a supporting column 4052 is fixed to the top surface of the fixing ring 4051, a vibration spring 4053 is fixed to the top surface of the fixing ring 4051, the upper end of the vibration spring 4053 is fixed to the filter screen 404, and a groove is provided on the bottom surface of the filter screen 404.

[0062] Specifically, the fixing ring 4051 will rotate under the drive of the transmission shaft 305, thereby driving the support column 4052 to intermittently hit the filter screen 404, thereby causing the filter screen 404 to vibrate up and down, and the crushed raw materials on the filter screen 404 will fall to the bottom of the filter screen 404 more smoothly.

[0063] Working principle: When processing feed, first start the motor 102, and the output shaft 103 will rotate through the cooperation of the reducer and the coupling. The output shaft 103 will drive the transmission cylinder 301 to rotate through the clamping column A303, and the transmission cylinder 301 will drive the blade 403 to rotate through the mounting shell 401.

[0064] When the hole of the granulation mold 203 is blocked, the resistance of the output shaft 103 will increase, and the column A303 on the output shaft 103 will break away from the limit of the slot A302 and move to the bottom of the transmission cylinder 301. The transmission cylinder 301 will slide on the transmission shaft 305, that is, the transmission cylinder 301 will rise, and the slot B304 on the transmission cylinder 301 will also rise. The slot B304 will resist the bottom of the column B306, and the output shaft 103 will continue to rotate. The friction between the output shaft 103 and the transmission cylinder 301 will drive the transmission cylinder 301 to rotate until the lower end of the column B306 is stuck in the right side of the slot B304. At this time, the output shaft 103 will no longer drive the transmission cylinder 301, and then disconnect the power component 1 from the roller 602, so that the user can judge the blockage condition of the granulation mold 203.
