Hoisting type lower header capable of crushing straws

Abstract

The invention discloses a hoisting type lower header capable of crushing straws. The hoisting type lower header is hinged to a front axle of a harvester; the lower header comprises a lower header main frame, a lower cutting mechanism, a straw crushing mechanism, a transmission mechanism and a lower header hoisting mechanism; the included angle of cutting blades on two sides of a cutting blade is 60 degrees and saw teeth are arranged on the cutting blade on each side; the lower header hoisting mechanism comprises a lower header hoisting oil cylinder, a lower header hoisting oil cylinder upper seat and a lower header hoisting oil cylinder lower seat; the lower header hoisting oil cylinder is a single acting cylinder. The hoisting type lower header capable of crushing the straws, disclosed by the invention, can be used for cutting and crushing straw parts remained after cereals are harvested; the feeding amount of the harvester is alleviated, the loss and threshing load of a machine are reduced and the threshing effect is improved; cutting stubbles are low and flat, so that a land is easy to plough; the cutting and crushing efficiency of the straws is high and the crushed straws can be directly overturned and pressed into soil in a ploughing process; the straws can also be used as a basic fertilizer after being returned to the field; the lower header can be hoisted so that the height of the cutting stubbles is controlled, obstacles can be avoided and the equipment safety can be protected.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an elevating lower cutting platform capable of crushing straw. Background technique [0002] At present, the country advocates that the straw should be returned to the field after harvesting, and then deeply plowed into the soil to fertilize the field. It is strictly forbidden to burn the straw. At the same time, the straw should be chopped and collected or returned to the field or not crushed. Also harvest the stalk portion of the grain. The cutting devices of today's harvesters are all composed of single-layer headers, which harvest the ears and stalks of the grain together, feed the cut grain stalks and ears of grain into the harvester, complete threshing and discharge the stalks . The disadvantages are that the cut stalks are long, the feeding amount is large, which affects the threshing effect, the machine is damaged, the energy consumption is high, and the ...

Problems solved by technology

The disadvantages are that the cut stalks are long, the feeding amount is large, which affects the threshing effect, the machine is damaged, the energy consumption is high, and the efficiency is low; The long straw is not easy to decompose after being returned to the field and becomes the base fertilizer
