Description

A roll pressing straw solidification forming machine

technical field

The invention relates to a machine for picking and bundling agricultural straws, in particular to a rolling and pressing type straw solidification molding machine.

Background technique

my country is a large agricultural country. After the crops are harvested, a large amount of straw is produced, and most of them will be burned on the spot, which not only wastes resources, but also pollutes the environment. Every autumn harvest season, the smog after straw burning has become one of the important pollution sources of the rural environment, and the economic loss and social harm it produces are far greater than the benefits it brings. At present, in the agricultural and animal husbandry production operations and in the grass storage process of family pastures, the straw baler (baler) has been used in daily production and life, mainly for picking up rice, wheat straw, forage grass, and corn straw for bundling. wait. After feeding, cutting, compacting and bundling, it is finally bundled into square or round bundles. The length and density of the bundle can be adjusted according to crop conditions, transportation and storage requirements, and it can be automatically and continuously operated, which is convenient for transportation, storage and deep processing. It is suitable for Recycling in various farms, pastures and various straws.
