Abstract

The invention relates to the field of agricultural machinery, in particular to a crop straw roll cutting operation mechanism. Two straw cutting rotors with opposite rotating directions are designed, wherein three cutters or above are arranged on the periphery of the first straw cutting rotor at intervals, and a straw cutting pillar of an elastic material is arranged on the periphery of the secondstraw cutting rotor. Under the rotation of the first straw cutting rotor and the second straw cutting rotor, the straw pillar of the elastic material has certain elastic deformation through contact ofthe cutters with the straw pillar and sinking of the cutters into the straw pillar, so that complete cutting off of crop straw is ensured when the crop straw passes through the cutters, and the quality and reliability of cutting are improved; and when the mechanism is compared with a traditional cutting device which adopts a rigid straw cutting pillar or a two-cutter winching mode, certain of errors are allowed when assembly is conducted, so that the equipment cost is reduced.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a crop straw rolling cutting operation mechanism. Background technique [0002] my country is the world's largest cotton producing country. When the production is high, the planting area of ​​more than 20 provinces and regions in the country reaches 90 million mu. It is an important economic crop in my country's agricultural production. For thousands of years, the cotton stalks after cotton picking are artificial Pulling and cleaning, cotton stalk removal and cleaning has become a very heavy physical work for cotton planting. This work is heavy and inevitable, and there is no good solution once and for all. For a long time, agricultural machinery experts from scientific research departments and enterprises in my country have invested a lot Manpower and material resources. In recent years, some technicians have used two chains to press and hold the stalks for the stalk pulling ...
