Description

Technical Field

[0001] The invention relates to the technical field of biological feed equipment, in particular to a premixing device and a mixing method for biological feed fermentation production. Background Art

[0002] Feed is a general term for food required by animals raised by humans. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives, etc., while biological feed is a further processing of ordinary feed. Biological feed refers to the use of feed raw materials and additives permitted by relevant national laws and regulations. It is a general term for feed products developed through bioengineering technologies such as fermentation engineering, enzyme engineering, protein engineering and genetic engineering. Biological feed can effectively improve the digestion and absorption rate of animals, effectively prevent and treat digestive tract diseases, reduce the mortality rate of young animals, enhance the body's immune function, and promote animal growth. The biological feed premixing device is usually composed of an agitator, a feeding system and a control system. The agitator can use mechanical stirring, air flow stirring or liquid circulation stirring to ensure uniform mixing of the raw materials. This premixing device and mixing method for biological feed fermentation production can improve the efficiency and quality of feed production, ensure uniform mixing of various feed raw materials, meet the nutritional needs of animals, and improve the fermentation effect and yield of biological feed.

6. A method for premixing biological feed fermentation production, using a premixing device for biological feed fermentation production as claimed in claim 5, characterized in that: The steps include: S1: Feed raw materials are poured into the feed box (104), and the feed enters the mixing drum (103) from the feed box (104). The servo motor (106) is started, and the servo motor (106) drives the rotating shaft (201) to rotate, so that the belt (202) drives the forward rotating shaft (203) to rotate, and the forward rotating shaft (203) drives the first crushing roller (204) to rotate. When the forward rotating shaft (203) rotates, the driving gear (205) contacts the driven gear (206), so that the driven gear (206) rotates in the opposite direction, and the driven gear (206) drives the reverse rotating shaft (207) and the second crushing roller (208) to rotate, and the second crushing roller (208) and the first crushing roller (204) crush the feed; S2: When the rotating shaft (201) rotates, the rotating shaft (201) drives the connecting rotating plate (301) to rotate, so that the arc-shaped rotating plate (302) drives the U-shaped support frame (303) to rotate, and the U-shaped support frame (303) drives the scraping knife (304) to stir the feed. Because the scraping knife (304) contacts the inner wall of the mixing barrel (103), the scraping knife (304) scrapes the mixing barrel (103), thereby preventing the feed from remaining in the mixing barrel (103) during the fermentation process. When the connecting rotating plate (301) rotates, the connecting rotating plate (301) drives the connecting shaft (305) to move, and the connecting gear (306) meshes with the annular gear plate (308). During the movement of the connecting shaft (305), the connecting shaft (305) rotates, so that the arc-shaped stirring plate (307) flips the feed; S3: The arc-shaped rotating plate (302) rotates. During the rotation of the rotating shaft (201), when the arc-shaped rotating plate (302) moves to a certain position, the centrifugal force generated by the rotating shaft (201) and the gravity of the gravity block (405) cause the movable plate (403) and the gravity moving plate (406) to expand outwards. The gravity block (405) slides in the connecting groove (407) and the sliding groove (404), so that the movable plate (403) and the gravity moving plate (406) cause the U-shaped support frame (303) to vibrate. When the vibration cleaning mechanism (4) moves one side of the top of the mixing drum (103), the gravity factor of the gravity block (405) causes the rotating shaft (201) to vibrate, thereby preventing the feed from remaining in the mixing drum (103). S4: When the rotating shaft (201) drives the rotating plate (505) to rotate, the sliding rod (504) slides in the reciprocating connecting groove (503), so that the reciprocating plate (502) reciprocates with the axial rod (501) as the axis, and the convex sliding block (507) slides in the sliding groove (506), so that the scratching rod (509) drives the sliding block (601) to slide in the limiting groove (605), so that the scratching plate (603) scratches the fixed screen plate (606).
