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 i

Embodiment Construction

[0014] exist figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 In the shown embodiment, a straw crushing mechanism of a corn harvester is installed on the bearing seat 1 under the header of the corn harvester, including the driven wheel 2 installed on the main shaft 3, and the tooth cutting knife is installed on the main shaft 3 4. The tooth cutting knife 4 installed on the main shaft 3 is fixed relative to the main shaft 3 as a reference object. A plurality of fixed knife assemblies 5 are installed near the rotation track of the tooth cutting knife 4. When rotating, the fixed knife assembly 5 The fixed knife 6 is inserted in the concave groove of the tooth cutting knife 4.

[0015] The fixed knife composition 5 is arranged and fixed on the same base plate 7 by a plurality of fixed knives 6 .

[0016] Working process: When the corn harvester is working forward, the driven wheel 2 is driven to rotate, and the tooth cutting knife 4 is rotated through the main shaft 3....

Abstract

The invention relates to a straw pulverizing mechanism for a corn harvester. The straw pulverizing mechanism is arranged below a cutting platform of the corn harvester to pulverize corn straws. A driven wheel, a bearing block and a tooth cutter are arranged on a spindle, and a fixed cutter assembly is transversely arranged close to the rotating trajectory of the tooth cutter; and a fixed cutter on the fixed cutter assembly is inserted into a groove of the tooth cutter during rotating. The pulverizing degree of straws is improved.

Description

technical field [0001] The invention relates to a corn harvester, in particular to a straw crushing mechanism 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 upright corn stalks, ...
