A New Traction Type Straw Pellet Forming Machine

technical field

The utility model relates to the technical field of agricultural machinery and equipment, in particular to a novel traction type straw particle forming machine.

Background technique

Straw is a general term for the stem and leaf parts of mature crops, usually referring to the remaining part of wheat, rice, corn and other crops after harvesting the seeds. Straw is rich in energy, contains a lot of nutrients, has great potential for development and utilization, has a high appreciation space, and has a very broad development prospect. The output of straw resources in my country is huge and various, especially the straw of wheat, rice and corn accounts for more than 90% of the total straw resources. In the past, the treatment of straw by farmers was random burning or discarding in the fields, which caused a serious negative impact on the environment and caused great waste. In recent years, with the advancement of agricultural mechanization technology and the improvement of public awareness of environmental protection, people have begun to pay more and more attention to the development and utilization of straw as a new biomass resource, such as using straw pellet molding equipment to make crop straw into biomass pellets. The resulting pellets can be used as feed or fuel. Studies have shown that: after feeding livestock with straw pellet feed, its digestion and absorption rate can be increased by more than 60%, milk production can be increased by more than 10%, and meat production can also be increased by more than 15% compared with ordinary feed.
