Harvester with fixed type lower header and capable of uniformly crushing straws and preventing crushed straws from spattering

Abstract

The invention discloses a harvester with a fixed type lower header and capable of uniformly crushing straws and preventing crushed straws from spattering. The harvester comprises the lower header, wherein the lower header is hinged to a front axle of the harvester; the lower header comprises a lower header main frame, a lower cutting mechanism, a straw crushing mechanism and a transmission mechanism; stopping angle iron capable of preventing the crushed straws from spattering is further fixedly connected with the rear part of a stopping cover of the lower header main frame; the included angle of cutting blades on two sides of a cutting blade is 60 degrees and saw teeth are arranged on the cutting blade on each side; the straw crushing mechanism is mounted in a containing space formed by a base, the stopping cover, a first sealing plate and a second sealing plate; an adjusting gap is formed in the top of a swinging arm. The harvester with the fixed type lower header and capable of uniformly crushing the straws and preventing the crushed straws from spattering, disclosed by the invention, can be used for cutting and crushing straw parts remained after cereals are harvested; the feeding amount of the harvester is alleviated, and the loss and threshing load of a machine are reduced; cutting stubbles are low and flat, so that a land is easy to plough; positions of the cutting blades can be easily and conveniently adjusted; high efficiency of cutting the straws is guaranteed and the crushing is uniform; meanwhile, the crushed straws do not spatter.

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 that crushes straw evenly and prevents 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 i...

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
