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

Abstract

The invention discloses a harvester with a climbing ladder and a fixed-type lower cutting table and capable of smashing straws. The harvester comprises the lower cutting table and the climbing ladder, the lower cutting table is fixedly welded on 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; and one end of a connection rod of the lower cutting table is fixedly welded on the front axle, the lower cutting mechanism comprises a plurality of linearly-arranged fixed cutter heads which are fixedly arranged on a base, and each cutting blade is parallel to the level ground. The harvester with the climbing ladder and the fixed-type lower cutting table and capable of smashing the straws 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; cut stubbles have a same height, and are low and smooth, thus land cultivation is convenient; cutting efficiency and smashing efficiency of the straws are high and the smashing is uniform, smashed straws can be directly overturned and pressed in soil when land is cultivated, and the returned straws are used as base fertilizer; 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 fixed lower cutting platform capable of crushing straw with a climbing 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. 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 ...
