Harvester with lifting lower header capable of crushing straws and preventing spatter of crushed straws

Abstract

The invention discloses a harvester with a lifting lower header capable of crushing straws and preventing spatter of the crushed straws. The harvester comprises the lower header, the lower header is hinged on a front axle of the harvester and comprises a lower header main frame, a lower cutting mechanism, a straw crushing mechanism, a driving mechanism and a lower header lifting mechanism, a blocking angle iron preventing spatter of the crushed straws is fixedly connected with the rear of a retaining cover of the lower header main frame, and the lower header lifting mechanism comprises a lower header lifting cylinder, a lower header lifting cylinder upper seat and a lower header lifting cylinder lower seat. According to the harvester with the lifting lower header capable of crushing the straws and preventing spatter of the crushed straws, straws remained after harvest of grains can be cut and crushed, feed quantity of the harvester is relieved, machine loss and threshing load are reduced, threshing effect is improved, cutting stubble is low and flat, lands are conveniently cultivated, cutting and crushing efficiency of the straws is high, crushed straws cannot spatter, the lower header can rise and fall, the height of the cutting stubble is controlled, barriers can be avoided, and device safety is protected.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester of a lifting type lower cutting platform capable of crushing straw and preventing the splashing of the broken 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...

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

In addition, the crushed stalks splash backward under the action of centrifugal force, and the broken stalks fall into the transmission system and hydraulic system to damage the machine, and also affect the driver's sight and cause accidents; the header is easy to hit obstacles and damage machinery and equipment
