Problems solved by technology

[0003] The problem to be solved by the present invention is that the current small and medium-sized corn harvesters use rotary horizontal knives to chop upright corn stalks, and the corn stalks that are inclined and enter horizontally have the phenomenon of missing cutting, and the blade is easy to blunt, which is suitable for soft and flexible corn cobs. It cannot be chopped, resulting in t

Abstract

Disclosed is a straw crushing mechanism under a corn harvesting machine header. The straw crushing mechanism is installed under the corn harvesting machine header and used for crushing corn straws. A driven wheel, bearing seats and claw-shaped tearing cutters are installed on a main shaft. A fixed cutter assembly is transversely installed at a position close to rotation tracks of the claw-shaped tearing cutters, and fixed cutters on the fixed cutter assembly and the claw-shaped tearing cutters are mutually embedded during rotation. By means of the straw crushing mechanism under the corn harvesting machine header, the straw crushing degree is improved.

Description

technical field [0001] The invention relates to a corn harvester, in particular to a straw crushing mechanism under the header of the corn harvester. Background technique [0002] The large-scale corn harvester that uses at present is to adopt post-mounted straw returning machine to pulverize corn stalks. The small and medium-sized corn harvester uses a rotating horizontal knife under the front cutting platform to chop upright corn stalks. The corn stalks that are inclined or horizontally enter the corn stalks are missed, and the blade is easy to blunt. It cannot cut the soft and flexible corn cobs. , resulting in too long stalks and high stubble, which cannot meet the requirements of agronomic planting, which is the main reason for the immaturity of small and medium-sized corn harvesters. Contents of the invention [0003] The problem to be solved by the present invention is that the current small and medium-sized corn harvesters use rotary horizontal knives to chop upri...
