Uniform straw smashing and smashed straw splattering prevention type double header linkage harvester with ladder stand

Abstract

The invention discloses a uniform straw smashing and smashed straw splattering prevention type double header linkage harvester with a ladder stand. The harvester comprises an upper header, a lower header, a linkage rod and the ladder stand. The upper header is hinged to a front axle, and the lower header is hinged to the front axle and positioned below the upper header. The upper header comprises an upper header main frame, an upper cutting mechanism, a screw, a reel and an upper header lifting mechanism. The lower header comprises a lower header main frame, a lower cutting mechanism, a straw smashing mechanism and a transmission mechanism, and a first right-angle side of a retaining angle iron is welded to the rear lower edge of a shield. The harvester has advantages that straws remained after grain harvesting can be cut and smashed, threshing load is relieved, cutting blade position can be adjusted easily and conveniently to guarantee high straw cutting efficiency and smashing uniformity, and smashed straws are prevented from splattering; the lower header is in lifting linkage with the upper header, and accordingly stubble height can be controlled while obstacles can be avoided so as to protect equipment safety, and energy saving and consumption reduction are realized; the ladder stand can be used for climbing safely and conveniently and can also serve as a safety fence.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester with a climbing ladder that crushes stalks evenly and prevents stalks from splashing and is coupled with double headers. 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 ef...

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
