The invention discloses a double-header harvester with a
crawling ladder and capability of uniformly crushing straws. The harvester comprises an upper header, a lower header and the
crawling ladder, the upper header is hinged onto a front axle of the harvester, the lower header is fixedly welded on the front axle of the harvester and 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, and the lower header comprises a lower header main frame, a lower
cutting mechanism, a
straw crushing mechanism and a transmission mechanism. A chamfer is arranged at an extending end of a
straw crushing blade to form a
cutting edge, the chamfer is positioned on the outer side of the
straw crushing blade, and an adjustment gap is formed in the top of a swing arm. The double-header harvester with the
crawling ladder and capability of uniformly crushing the straws can
cut and crush the straws remaining after grain harvesting, the feed quantity of the harvester is reduced, loss and the
threshing load of the harvester are reduced, and
threshing effects are improved. The heights of
cut stubbles can be kept consistent, the
cut stubbles are low and smooth, plowing is facilitated, the straws are uniformly crushed, and the crawling ladder can be used for safe and convenient climbing and can also be used as a safety fence.
