Harvester with ladder and double headers adjustable in cutting blades

Abstract

The invention discloses a harvester with a ladder and double headers adjustable in cutting blades. The harvester comprises an upper header, a lower header and the ladder, the upper header is hinged to a harvester front axle, the lower header is fixedly welded to the harvester front axle and located below the upper header, the upper header comprises an upper header main frame, an upper cutting mechanism, an auger, a reel and an upper header lifting mechanism, and the lower header comprises a lower header main frame, a lower cutting mechanism, a straw crushing mechanism and a transmission mechanism; a lower header connecting rod forms a 15-degree included angle with the horizontal surface; an included angle of cutting edges on two sides of each cutting blade is 60 degrees; an L-shaped hinge bar is fixed to a movable blade seat. The harvester has the advantages that straw parts left after grain harvesting can be cut and crushed; and feed amount of the harvester is reduced; cut stubbles are low and flat to bring convenience to land cultivation; the cutting blades can be adjusted in position easily and conveniently, and high efficiency of straw cutting and crushing is guaranteed; the ladder arranged can be used for climbing safely and conveniently as well as used as a safety guard.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester with adjustable ladder cutting blades and double headers. 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, a...
