Dustproof harvester

Abstract

The invention discloses a dustproof harvester which comprises a traveling chassis, an operation platform, a straw pulling instrument, a shearing instrument, a conveying chain, a threshing mechanism and a screening mechanism, wherein the threshing mechanism comprises a threshing cylinder and a concave grid, the axial direction of the threshing cylinder is parallel to the forward direction of the combine harvester, a grass discharging opening of the threshing mechanism is arranged at the tail of the shaft end of the threshing cylinder, a stirring chamber is arranged below the grass discharging opening, is fixed on a rack, is provided with a water injection vessel, and is internally provided with a stirring rod driven by a motor, and the a throwing opening is formed in the top end of the water injection vessel. According to the dustproof harvester, straws cut by the harvester is directly put into the stirring chamber, water and a leavening agent are injected into the stirring chamber, so that flocculent straw powder becomes a mixture to be discharged from the harvester, the straw powder is prevented from floating in air to be absorbed into human bodies, and the rot speed of the straw is increased.

Description

technical field [0001] The invention relates to a harvester, in particular to a dust-proof harvester. Background technique [0002] The combine harvester is a combined machine for harvesting crops. It can complete the processes of harvesting, threshing, separating straw, and removing debris at one time. And most of existing combine harvesters often directly throw the stalk after the chopping and the debris into the field when processing the stalks and the debris removed, so that although the stalks can be used as fertilizers to fertilize the soil after they rot, During the throwing process, a large amount of dust floats in the air and flies randomly, which not only pollutes the surrounding air environment, but also easily sucks the dust into the lungs or confuses the eyes of the staff when they are working on site. , not only affect human health, but also easily cause safety accidents. In addition, the straws are directly sprinkled on the field, and it takes a long time to ...

And most of existing combine harvesters often directly throw the stalk after the chopping and the debris into the field when processing the stalks and the debris removed, so that although the stalks can be used as fertilizers to fertilize the soil after they rot, During the throwing process, a large amount of dust floats in the air and flies randomly, which not only pollutes the surrounding air environment, but also easily sucks the dust into the lungs or confuses the eyes of the staff when they are working on site. , not only affect human health, but also easily cause safety accidents. In addition, straws are directly sprinkled on the field, and it takes a long time to decompose. When the farmers plow the land next time, these long straws that have not rotted will affect the operation
