Harvester which has climbing ladder, smashes straws uniformly, prevents smashed straws splashing and has lifting-type double cutting tables

Abstract

The invention discloses a harvester which has a climbing ladder, smashes straws uniformly, prevents smashed straws splashing and has lifting-type double cutting tables. The harvester has an upper cutting table, a lower cutting table and a climbing ladder, the upper cutting table is hinged onto a front axle, the lower cutting table is hinged onto the front axle and is located below the upper cutting table, the upper cutting table comprises an upper cutting table main frame, an upper cutting mechanism, an auger, a reel and an upper cutting table life mechanism, and the lower cutting table comprises a lower cutting table main frame, a lower cutting mechanism, a straw smashing mechanism, a drive mechanism and a lower cutting table lift mechanism; and a first right-angle side of a blocking angle iron is welded to the lower edge of the rear part of a blocking cover. The harvester can cut and smash the residual straws after grains are harvested, thus harvester loss and a threshing load are reduced, positions of cutting blades can be easily and conveniently adjusted, thus high efficiency of straw cutting and uniform smashing are guaranteed, and the smashed straws cannot be splashed; and the lower cutting table can be lifted, thus a stubble cutting height is controlled, obstacles can be avoided, and harvester security is protected; and the arranged climbing ladder can be used for safe and convenient climb, 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 ladders for evenly crushing stalks and anti-splashing lifting double cutting platforms. 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...

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
