Description

Technical Field

[0001] The utility model relates to the field of harvesting, in particular to the technical field of silage harvesting, and specifically refers to a crushing and kneading device. Background Art

[0002] Silage is a type of feed that is made from water-rich plant feed that has been sealed and fermented. It is mainly used to feed ruminants. Silage is more durable than fresh feed and has stronger nutritional content than dry feed. In addition, silage storage takes up less space and does not pose a fire risk.

[0003] Silage is a kind of roughage obtained by chopping green fodder with a moisture content of 65%-75% and fermenting it under closed and anoxic conditions through anaerobic lactic acid bacteria to inhibit the reproduction of various bacteria. Silage has a sour and fragrant smell, is soft and juicy, has good palatability, is rich in nutrition, and is conducive to long-term storage. It is an excellent source of feed for livestock.

[0004] When silage is being harvested, the driver drives the harvester and moves. The silage material is harvested by the cutter and enters the grinder through the conveying trough for crushing. Finally, the feed is transported to the discharge box. A bracket is provided on the crushing shaft in the crushing bin, and a crushing curved knife is provided on the bracket. The crushing curved knife currently used has a poor crushing effect. Utility Model Content
