Reaping machine capable of uniformly chopping straws and preventing chopped straws from splashing and having double headers

Abstract

The invention discloses a reaping machine capable of uniformly chopping straws and preventing chopped straws from splashing and having double headers. The reaping machine comprises an upper header and a lower header, wherein the upper header is hinged to a front axle of the reaping machine; the lower header is fixedly welded to the front axle of the reaping machine and is positioned 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; the lower header comprises a lower header main frame, a lower cutting mechanism, a straw chopping mechanism and a transmission mechanism; a first right-angle side which stops angle iron is welded to the lower edge of the rear of a stopping cover; and a second right-angle side is positioned below the first right-angle side. By the reaping machine capable of uniformly chopping straws and preventing chopped straws from splashing and having the double headers, straws remaining after reaping of grains can be reaped and chopped, the feeding amount of the reaping machine is reduced, and machine loss and threshing load are reduced; stubbles are low and flat, and ploughing is facilitated; and the positioning of cutting blades can be adjusted easily and conveniently, high straw reaping efficiency and uniform chopping are ensured, and meanwhile, the chopped straws cannot be splashed.

Description

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

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
