Harvester with ladder, adjustable cutting blades and fixed lower cutting table

Abstract

The invention discloses a harvester with a ladder, adjustable cutting blades and a fixed lower cutting table. The harvester comprises a lower cutting table and a ladder; the lower cutting table is fixedly welded on a front axle of the harvester, and comprises a lower cutting table main frame, a lower cutting mechanism, a crushing mechanism and a transmission mechanism; the included angle between a connecting rod of the lower cutting table and the horizontal ground is 15 degrees; the included angle between the blades on both sides of the cutting blade is 60 degrees; an L-shape hinge rod is fixed on a movable cutter seat; a straight corner edge of the hinge rod is welded to the movable cutter seat; the other corner edge is hinged to an end of a swing arm connecting joint; and the top of the swing arm is provided with an adjusting gap. The harvester with the ladder, the adjustable cutting blades and the fixed lower cutting table provided by the invention can cut and crush remaining straw parts after grains are harvested, so the feeding amount of the harvester is reduced and the threshing effect is improved. The stubble is low and flat and is convenient for field ploughing; the position of the cutting blades can be easily and conveniently adjusted, so that high efficiency of cutting and crushing the straw is ensured; and the arranged ladder not only can be used for safely and conveniently climbing, but also can be used as a safety barrier.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester with a fixed lower cutting platform with an adjustable ladder cutting blade. 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. 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 efficiency is low; The long straw is not easy to decompose after being ret...
