Lift type double-cutting-table harvester capable of pulverizing straws and preventing splashing of pulverized straws

Abstract

The invention discloses a lift type double-cutting-table harvester capable of pulverizing straws and preventing splashing of the pulverized straws. The harvester comprises an upper cutting table and a lower cutting table, wherein the upper cutting table is hinged to a front axle; the lower cutting table is hinged to the front axle and positioned below the upper cutting table; the upper cutting table comprises an upper cutting table main frame, an upper cutting mechanism, a screw conveyer, a reel and an upper cutting table lifting mechanism; the lower cutting table comprises a lower cutting table main frame, a lower cutting mechanism, a straw pulverizing mechanism, a transmission mechanism and a lower cutting table lifting mechanism; and a first right-angle side of blocking angle iron is welded on the lower edge at the back part of a blocking cover. The lift type double-cutting-table harvester capable of pulverizing straws and preventing splashing of the pulverized straws can cut and pulverize the straw parts remaining after grain harvesting, thereby decreasing the feed quantity of the harvester, reducing the machine loss and threshing load, and improving the threshing effect; the cutting height is low, and stubble is flat, thereby facilitating land cultivation; the cutting and pulverizing efficiency of the straws is high, the straws are uniformly pulverized, and splashing of the pulverized straws can be prevented; and the lower cutting table can be lifted, so that the cutting height can be controlled, and obstacles can be avoided, thereby protecting the safety of the equipment.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester with lifting double headers capable of crushing stalks and preventing 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 dam...

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
