Harvester capable of smashing straw with lifting double-cutting tables

Abstract

The invention discloses a harvester capable of smashing straw with lifting double-cutting tables. The harvester comprises an upper cutting table and a lower table, the upper cutting table is hinged to a harvester front axle, and the lower cutting table is hinged onto the harvester front axle and located below the upper cutting table; the upper cutting table comprises an upper cutting table main rack, an upper cutting mechanism, an auger, a reel and an upper cutting table lifting mechanism, and the lower cutting table comprises a lower cutting table main rack, a lower cutting mechanism, a straw crushing mechanism, a transmission mechanism and a lower cutting table lifting mechanism. The harvester capable of smashing straw with the lifting double-cutting tables can cut and smash remaining straw parts after grain harvest, reduce the feeding amount of the harvester, reduce the machine loss and threshing load, and improve the threshing effect; the cutting height is low and cutting is flat, so that ploughing is facilitated; the cutting and smashing efficiency of the straw is high, the smashing degree is even, the smashed straw can be directly turned and pressed into soil in ploughing, and after returning to the field, the straw can be used as base fertilizer; the lower cutting table can be lifted so that the cutting height can be controlled and the obstacles can be avoided, and the safety of the harvester is guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester with lifting double headers capable of crushing 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. 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, the energy consumption is high, and ...

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
