Harvester with climbing ladder and fixed-type lower cutting table and capable of smashing straws uniformly

Abstract

The invention discloses a harvester with a climbing ladder and a fixed-type lower cutting table and capable of smashing straws uniformly. The harvester comprises the lower cutting table and the climbing ladder, the lower cutting table is fixed to a front axle of the harvester, and the lower cutting table comprises a lower cutting table main frame, a lower cutting mechanism, a straw smashing mechanism and a drive mechanism; the lower cutting table main frame comprises a fixed rod; an included angle of cutting edges at two sides of each cutting blade is 60 degrees, and each side of the cutting edges is provided with sawteeth; the extended end of each straw smashing blade is provided with a chamfer which is used to form a cutting edge, and each chamfer is located at the outer side of the corresponding straw smashing blade; and the top of a swing arm is provided with an adjustment gap. The harvester with the climbing ladder and the fixed-type lower cutting table and capable of smashing the straws uniformly can cut and smash the straws remained after grains are harvested, alleviates the harvester feeding quantity, reduces harvester loss and threshing load, and improves the threshing effect; the height of cut stubbles can be kept consistent, cut stubbles are low and smooth, thus land cultivation is convenient; straw smashing is uniform; and the climbing ladder arranged in the harvester can be used for safe and convenient climbing, and can be used as a safety guard bar.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester with a ladder and 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. 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 efficiency is low; The long straw is not easy to decompose after being retu...
