Description

Technical Field

[0001] The utility model relates to the technical field of feed crushing, in particular to a feed crushing device. Background Art

[0002] Feed is a general term for food for animals, mainly referring to the food for animals raised in agriculture or animal husbandry. The main raw materials of feed are soybean, corn, fish meal, amino acid, additives, whey powder, fat, meat and bone meal, grains and sorghum, etc. Straw feed mainly refers to fiber feed made from crushed sweet sorghum, corn, reed, cotton and other straw, which is the main feed for ruminants.

[0003] In the production process of straw feed, the feed needs to be crushed to obtain feed with smaller particles to meet different usage requirements.

[0004] Most of the existing feed crushing devices can only crush the feed once. However, since straw feed is a fibrous feed, the feed particles obtained by crushing once are relatively large and difficult to meet the use requirements. Therefore, repeated crushing is required, resulting in low crushing efficiency. Utility Model Content

[0005] In view of the above problems, the purpose of the utility model is to provide a feed crushing device to solve the problem that since straw feed is a fibrous feed, the feed particles obtained by one crushing are large and difficult to meet the use requirements, so repeated crushing is required, resulting in low crushing efficiency. When the grinding drill bit rotates driven by the connected rotating shaft, the grinding drill bit drives the crushing knife to rotate periodically during the rotation process, and is used to further crush the feed entering the crushing chamber of the grinding seat, thereby ensuring the effect of feed crushing.
