Abstract

The invention discloses a double-header harvesting machine with adjustable cutting blades. The double-header harvesting machine comprises an upper header and a lower header, the upper header is hinged on a front axle of the harvesting machine, the lower header is fixedly welded on the front axle of the harvesting machine and positioned below the upper header, the upper header comprises an upper header main frame, an upper cutting mechanism, a screw conveyer, a reel and an upper header lifting mechanism, the lower header comprises a lower header main frame, a lower cutting mechanism, a straw crushing mechanism and a transmission mechanism, a 15-degree included angle is formed between each lower header connecting rod and the level ground, a 60-degree included angle is formed between cutting edges on two sides of each cutting blade, and an L-shaped hinge rod is fixed on a movable blade holder. According to the double-header harvesting machine, residual straws after grain harvesting can be cut and crushed, the feeding quantity of the harvesting machine is reduced, machine loss and threshing load are reduced, threshing effects are improved, stubbles are low and smooth, land is conveniently plowed, positions of the cutting blades can be easily and conveniently adjusted, and high cutting and crushing efficiency of the straws is ensured.

Description

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