Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing:

[0034] Such as figure 1 As shown, the fixed lower cutting platform with evenly crushed straw is fixed on the front axle of the harvester, which includes the main frame of the lower cutting platform 31, the lower cutting mechanism 32, the straw crushing mechanism 33 and the transmission mechanism 34;

[0035] Such as figure 2 , 3, 4, and 5, the bottom of the main frame 31 of the lower header is provided with a base 311, one end of the base 311 is fixed with a first sealing plate 312, and the other end is fixed with a second sealing plate 313, on the base 311 An arc-shaped baffle 314 is arranged above, and the first sealing plate 312 and the second sealing plate 313 are respectively fixed on both ends of the baffle 314, and the first sealing plate 312 and the second sealing plate 313 are fixed on the top of the baffle 314. The support plate 315 between is fixedly connecte...

Abstract

The invention discloses a fixed lower header capable of uniform straw smashing. The fixed lower header is fixed on a front axle of a harvester and comprises a lower header main frame, a lower cutting mechanism, a straw smashing mechanism and a transmission mechanism, wherein the lower header main frame also comprises a fixation rod; the included angle between cutting edges on two sides of a cutting blade is 60 DEG, and sawteeth are disposed on the cutting edge of each side; the straw smashing mechanism is installed in storage space which is formed through enclosing of a base, a blocking cover, a first seal plate and a second seal plate, a chamfer is disposed on an extending end of the straw smashing blade to form a cutting edge, and the chamber is located on the outer side of the straw smashing blade; and an adjustment gap is formed in the top of a sway arm. The fixed lower header capable of the uniform straw smashing 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, machine losses and threshing loads are reduced, and threshing effects are enhanced; stubble cutting heights can be kept consistent, and stubble cutting is low and smooth, so ploughing becomes easy; and straw smashing is uniform.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a fixed lower cutting platform with evenly crushed 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 high, and the effic...
