Double-header harvester capable of preventing splashing of crushed straw

Abstract

The invention discloses a double-header harvester capable of preventing the splashing of crushed straw. The double-header harvester comprises an upper header and a lower header and is characterized in that the upper header is hinged to the front axle of the harvester, the lower header is fixedly welded to the front axle of the harvester 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; the first right-angle edge of blocking angle iron is welded to the lower edge of the rear portion of a retaining cover, and the second right-angle edge of the blocking angle iron is located below the first right-angle edge and vertical to the horizontal ground; each cutting blade is parallel with the horizontal ground. The double-header harvester has the advantages that straw left after grain harvesting can be cut and crushed, the feeding quantity of the harvester is reduced, and machine loss and threshing load are lowered; stubbles are low and flat, so that plowing is facilitated; high straw crushing efficiency is achieved, and the splashing of the crushed straw is prevented.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a double-head harvester capable of preventing broken 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 damaged, the energy consumption is h...

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
