[0002] Feed fermentation uses microorganisms and complex enzymes as biological feed fermentation agents to convert feed raw materials into a biological fermentation feed that includes microbial bacterial protein, bioactive small peptide amino acids, microbial active probiotics, and complex enzyme preparations. The fermented feed has the advantages of rich nutrition, aromatic taste, good palatability, easy digestion and absorption of nutrients. The demand for fermented feed is also increasing, and there are many kinds of raw materials suitable for crushing and fermentation, such as king grass, corn stalks, peanut vines, wheat straw, soybean straw, melon vines, etc.

[0055] Step 4: After the arc-shaped stirring blade 206 is adjusted to the original position, the chopped feed raw materials move outward along the arc-shaped stirring blade 1 204 and the arc-shaped stirring blade 206, and the crushing mechanism 4 is started to further crush and crush the chopped feed raw materials, and further stir the feed raw materials, and the arc-shaped scraping blade 203 scrapes up the feed raw materials adhering to the inner bottom wall of the fermentation tank body 101, and moves upward along the arc-shaped scraping blade 203, so that the feed raw material particles that have settled on the bottom move to the middle of the fermentation tank body 101, thereby accelerating the stirring, mixing and fermentation of the feed raw materials;

[0056] Step 5: When the fermentation is completed, the control valve 109 is opened to discharge the fermented feed material through the discharge pipe 108 .

[0057] Specifically, the crushing mechanism 4 further crushes the feed raw material lumps after the initial crushing, and cooperates with the stirring mechanism 2 to accelerate the dissolution of the crushed feed raw material particles into the feed raw material solution, thereby improving the stirring, mixing and fermentation efficiency of the feed raw materials.

[0058] Working principle: First, feed raw materials and clean water are injected into the fermentation tank body 101 through the feed pipe 104. During the process, fermentation bacteria are continuously sprayed into the fermentation tank body 101 through the bacteria injection nozzle 105. The injection amount is observed through the observation port 1010. After the injection amount is flush with the lower end of the observation port 1010, the injection of feed raw materials, clean water and the spraying of fermentation bacteria are stopped, and sealed fermentation is performed. During the fermentation process, oxygen is injected into the fermentation tank body 101 through the oxygen delivery pipe 107, and exhaust gas is discharged through the exhaust gas discharge pipe 106. During the oxygen injection process, the motor 201 is started, and the arc stirring blade 1 204 and the arc stirring blade 2 206 are driven to rotate through the stirring shaft 202 to stir the feed raw materials so that oxygen is fully mixed with the feed raw materials. The feed raw materials are mixed and the waste gas in the feed raw materials is quickly discharged. When the feed raw materials are stirred in the later stage of fermentation, the cylinder 302 is started, and the tripod 304 is driven to descend through the sliding sleeve 303, and then the arc-shaped stirring blade 206 is driven to rotate outside the arc-shaped stirring blade 1 204 through the cooperation of the limiting bead 1 307 and the arc-shaped groove 1 306 on the outer periphery of the adjusting shaft 305, and the stirring blade shape composed of the arc-shaped stirring blade 1 204 and the arc-shaped stirring blade 2 206 is adjusted, and then the stirring efficiency is adjusted. Through the cooperation of the stirring mechanism 2 and the adjusting mechanism 3, it is achieved that during the fermentation process, the stirring efficiency can be adjusted according to the degree of fermentation, which is beneficial to the fermentation of the feed raw materials. When it is found that agglomeration occurs in the feed raw materials inside the fermentation tank body 101 When the situation occurs, the cylinder 302 is started, and the long cutting knife 208 outside the arc-shaped stirring blade 206 is adjusted to move to the position of the agglomerated feed raw materials, and the agglomerated feed raw materials are cut into pieces. A part of the crushed feed raw materials moves to the inner periphery of the fermentation tank body 101, and the other part is retained in the angle between the arc-shaped stirring blade 1 204 and the arc-shaped stirring blade 206. In the process of the long cutting knife 208 crushing the agglomerated feed raw materials, the electric push rod 401 is started, and the ramming shaft 404 is driven to move up and down through the connecting frame 403, thereby driving the oblique punching knife 408 and the oblique cutting knife 409 at the lower end to further crush the initially crushed agglomerated feed raw materials. At the same time, the limiting bead 206 inside the adjusting sleeve 4010 and the outer surface of the ramming shaft 404 are adjusted. The arc groove 205 around the fermenter can drive the oblique punch 408 and the oblique cutting knife 409 to reciprocate, further crush the initially crushed feed raw material lumps, and cooperate with the stirring mechanism 2 to accelerate the crushed feed particles to fully dissolve into the feed raw material mixture. At the same time, the arc scraping blade 203 can scrape up the feed particles adhering to the bottom of the fermentation tank body 101 and sinking to the bottom of the fermentation tank body 101, move upward along the arch side of the arc scraping blade 203, and cooperate with the arc stirring blade 1 204, the arc stirring blade 206, the oblique punch 408 and the oblique cutting knife 409 to dissolve the feed raw material particles that sink to the bottom after crushing into the feed raw material mixture. When one crushing is completed, the cylinder 302 is started to reset the arc stirring blade 206.The remaining preliminarily crushed feed raw material particles are moved to the inner periphery of the fermentation tank body 101 along the arc side formed by the arc-shaped stirring blade 1 204 and the arc-shaped stirring blade 2 206, and are crushed and mixed by the crushing mechanism 4. Through the cooperation of the stirring mechanism 2 and the regulating mechanism 3, the agglomerated feed raw materials can be preliminarily crushed, and the preliminarily crushed feed raw materials can be moved to the inner periphery of the fermentation tank body 101 twice, which is convenient for the crushing mechanism 4 to further crush the agglomerates of the preliminarily crushed feed raw materials. The crushing mechanism 4 further crushes the agglomerates of the preliminarily crushed feed raw materials, and cooperates with the stirring mechanism 2 to accelerate the dissolution of the crushed feed raw material particles into the feed raw material solution, thereby improving the stirring, mixing and fermentation efficiency of the feed raw materials. By arranging the arc-shaped scraping blade 203 at the outer periphery of the lower end of the stirring shaft 202, the feed particles adhering to and sinking to the bottom of the fermentation tank body 101 can be scraped up, and move upward along the arc side of the scraping blade 203, which is convenient for the stirring mechanism 2 and the crushing mechanism 4 to stir, mix and ferment the feed particles.
