Abstract

The invention discloses a harvester capable of chopping straw and provided with a fixed lower cutting table. The harvester comprises the lower cutting table. The lower cutting talbe is fixedly welded on a front axle of the harvester, and comprises a lower cutting table main frame, a lower cutting mechanism, a straw chopping mechanism and a transmission mechanism. One end of each of lower cutting table connecting rods is fixedly welded on the front axle. The lower cutting mechanism comprises a plurality of fixed tool bits which are arranged in a straight line and fixedly arranged on a base. Each cutting blade is parallel to the horizontal ground. The straw chopping mechanism is mounted in an accommodating space defined by the base, a covering shelter, a first sealing plate and a second sealing plate. The harvester has the advantages that the straw parts left after harvesting of crops can be cut and chopped, the feeding quantity of the harvester is reduced, the machine loss and the threshing load are reduced, the threshing effect is improved, the cut stubble heights are consistent, low and level and convenient for ploughing, the cutting and chopping efficiency of the straw is high, the chopped straw can be directly plough down in the soil in ploughing, and the straw is used as a base fertilizer after returning to the field.

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 capable of crushing straw. 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 hi...
