Group difference type corn harvester cutting knife assembly

Abstract

The invention relates to the technical field of agricultural implement components, and particularly discloses a group difference type corn harvester cutting knife assembly. The assembly comprises a frame, wherein a dynamic cutter and a static cutter are mounted in the frame; the dynamic cutter comprises a shaft; a plurality of extended dynamic blades are mounted on the shaft; the static cutter is fixed on the frame; the static cutter comprises a plurality of static blades; the static blades form two groups; the two groups of static blades are arranged in front and rear of the track of the dynamic blades, and form a first group of static blades in the front and a second group of static blades in the rear; a crushing section is arranged between every two dynamic blades; the assembly is characterized in that the quantity of the first group of static blades is smaller than that of the second group of static blade. The assembly has the advantage of high crushing efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural tool parts, in particular to a corn harvester cutter assembly. Background technique [0002] The corn harvester has a cutter assembly, the cutter assembly includes a shelf, a moving knife and a static knife are installed in the shelf, the moving knife includes a shaft, and a plurality of protruding moving blades are installed on the shaft, and the static knife is fixed On the shelf, the movable knives and the static knives are engaged with each other to crush the corn stalks. In order to improve the crushing ability of the straw, multiple sets of static knives are set on the shelf; the number of each set of static knives is the same in the prior art. Such cutter assembly has the disadvantage of limited ability to improve crushing, and cannot meet some production requirements. Contents of the invention [0003] The object of the present invention is to address the above disadvantages, and t...
