Harvester of fixed lower header capable of preventing splashing of broken straws

Abstract

The invention discloses a harvester of a fixed lower header capable of preventing splashing of broken straws. The harvester comprises the lower header, wherein the lower header is firmly welded on a front axle of the harvester and comprises a lower header main frame, a lower cutting mechanism, a straw breaking mechanism and a transmission mechanism. The harvester also comprises a fixation rod and blocking angle iron, wherein a first right angle edge of the blocking angle iron is welded on the lower edge of the rear part of a blocking cover; and a second right angle edge is located under the first right angle edge and perpendicular to the horizontal ground. Each cutting blade is parallel to the horizontal ground. The transmission mechanism comprises a chain, a driven chain wheel, a first transmission shaft, a first pulley, a first belt, a second pulley, a second transmission shaft, a third pulley, a third belt, a tensioning pulley and a tensioning pulley installation shaft. The harvester of the fixed lower header capable of preventing the splashing of the broken straws disclosed by the invention has the advantages that straw parts left after cereal reaping can be cut and smashed, so a feeding amount of the harvester can be reduced, and machine losses and threshing loads can be reduced; stubble cutting is low and smooth, so ploughing becomes easier; and straw smashing efficiency is high, and the broken straws will not be splashed.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester with a fixed lower header capable of preventing broken 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 disadvantage is that the cut stalks are long, the feeding amount is large, which affects the threshing effect, the machine is damaged, the energy cons...

AI Technical Summary

Problems solved by technology

The disadvantage is 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; at the same time, some grains will be mixed into the stalks and taken out, and the grain loss will be large; in addition, The longer straw is not easy to decompose and become base fertilizer after being returned to the field. The crushed straw is splashed backward under the action of centrifugal force, and it is easy to fall into the transmission system and hydraulic system to damage the machine, and it will also affect the driver's sight and cause accidents.
