Harvester with fixed lower cutting header and capable of evenly smashing straws

Abstract

The invention discloses a harvester with a fixed lower cutting header and capable of evenly smashing straws. The harvester comprises a lower cutting header. The lower cutting header is fixed on a front axle of the harvester and comprises a lower cutting header main frame, a lower cutting mechanism, a straw smashing mechanism and a transmission mechanism, wherein the lower cutting header main frame further has a fixing rod; an included angle of cutting edges on two sides of each cutting blade is 60-degree; sawteeth are arranged on each side cutting edge; the straw smashing mechanism is disposed in accommodating space enclosed by a pedestal, a baffle cover, a first sealing plate and a second sealing plate; an extending end of a straw smashing blade is provided with a chamfer to form a cutting edge; the chamber is arranged on the outside of the straw smashing blade; and an adjusting gap is formed in the top of a swinging arm. Straw parts left after grain harvest can be cut and smashed by the harvester with a fixed lower cutting header and capable of evenly smashing straws, so feed quantity of the harvester can be reduced and machine loss and threshing load can be reduced; threshing effect can be enhanced; the height of stubble cutting can be remained the same; stubbles can be cut at low height and tidy thereby facilitating plantation; and straws can be evenly smashed.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester of a fixed lower cutting platform with evenly crushed 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...

AI Technical Summary

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
