Shredding device for stalk sundries obtained after threshing by harvester

Abstract

The invention discloses a shredding device for stalk sundries obtained after threshing by a harvester. The shredding device comprises a left vertical plate and a right vertical plate which are parallel to each other; a supporting plate is arranged between the left vertical plate and the right vertical plate; one end of the supporting plate is hinged with a rack of the harvester; the supporting plate is located below a rotating drum; the outer wall of the rotating drum is provided with a plurality of assembling plates on which moving blades are arranged; the supporting plate is correspondingly provided with a plurality of fixed blades; a belt pulley at the outer side of the right vertical plate is connected with the rotating drum and is connected with a driving device by a driving belt; and the outer wall of the left vertical plate is provided with a regulating device for regulating the distances between the fixed blades and the moving blades. By using the shredding device, the threshed stalk sundries discharged from the drum are shredded by a grain direct harvester, the moving blades in double spiral lines have the shredding effect, and the distances between the fixed blades and the moving blades can be regulated by the regulating device, so that the ideal stalk cutting length is obtained, rough cutting, medium cutting or accurate cutting is realized, and the subsequent agriculture requirement is met.

Description

technical field [0001] The invention belongs to the field, and in particular relates to a shredding device for stalk debris after threshing of a harvester. Background technique [0002] Harvester, also known as harvester, is an integrated machine for harvesting crops. It completes harvesting and threshing at one time, and collects grains into storage bins, and then transports grains to transport vehicles through conveyor belts. It can also be harvested manually, and the stalks of crops such as rice and wheat are spread in the field, and then picked up and threshed by grain harvesting machinery. Crop harvesting machinery for harvesting grains and straws of cereal crops such as rice and wheat. [0003] Harvesters can be divided into side-mounted harvesters, knapsack harvesters, walk-behind harvesters, horizontal harvesters, and vertical harvesters according to their structure types. [0004] At present, the threshing stalks of the full-feed combine harvester are usually dire...

Problems solved by technology

[0004] At present, the threshing stalks of the full-feed combine harvester are usually directly discharged from the threshing chamber to the field. Because the discharged stalks are long, they are not easy to rot after falling into the field, which affects the growth of subsequent crops; in order to solve this problem, Farmers often burn the stems that fall into the field, which not only pollutes the environment, but also destroys the organic components of the stems, making the stems unable to return to the field well
