Lifting-type double-header reaper capable of uniformly smashing straws and preventing smashed straw spatter

Abstract

The invention discloses a lifting-type double-header reaper capable of uniformly smashing straws and preventing smashed straw spatter. The reaper includes an upper header and a lower header, wherein the upper header is hinged with a front bridge, and the lower header is hinged with the front bridge and positioned under the upper header; the upper header includes a main upper header frame, an upper cutting mechanism, an auger, a reel and an upper header lifting mechanism, and the lower header includes a main lower header frame, a lower cutting mechanism, a straw smashing mechanism, a transmission mechanism and a lower header lifting mechanism; the first right-angle side of a blocking angle iron is welded on the lower edge of the back part of a blocking cover. The lifting-type double-header reaper capable of uniformly smashing straws and preventing smashed straw spatter can cut and smash remaining straw parts of grain after reaping, decrease the feeding amount of the reaper and reduce the machine loss and the threshing load, and the reaper can easily and conveniently adjust the position of a cutting blade so as to ensure the high efficiency and uniform smashing of straw cutting and make the smashed stalks not spatter; moreover, the lower header can conduct lifting to control the straw cutting height and avoid obstacles to protect the equipment safety.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester with lifting double headers that crushes straw evenly and prevents the stalks from splashing. 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 damage...

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
