Harvester provided with protective ladder and lower lifting header and capable of smashing straw

Abstract

The invention discloses a harvester provided with a protective ladder and a lower lifting header and capable of smashing straw. The harvester comprises the lower header and the protective ladder, wherein the lower header is hinged to a harvester front axle and comprises a lower header main frame, a lower cutting mechanism, a straw smashing mechanism, a driving mechanism and a lower header lifting mechanism. An included angle of cutting edges on two sides of a cutting blade is 60 angles. The lower header lifting mechanism comprises a lower header lifting oil cylinder, a lower header lifting oil cylinder upper seat and a lower header lifting oil cylinder lower seat wherein the lower header lifting oil cylinder is a single acting cylinder. The harvester provided with the protective ladder and the lower lifting header and capable of smashing straw can cut and smash grains and harvest residual straw portions, a threshing effect is improved, and cut stubbles are short and flat and facilitate land cultivation. The straw cutting and smashing efficiency is high, smashing is uniform, and the straw is used as a base fertilizer after being returned to fields. The lower header can lift so as to control the stubble cutting height and can avoid obstacles to ensure device safety. The arranged protective ladder can be used for safe and convenient climbing and can be also used 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 lift-type lower cutting platform capable of crushing straw with a protective ladder. 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,...
