Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery equipment, and more specifically, relates to a straw cleaning device for a wide and narrow row seeder. Background Technique

[0002] Most of the existing wheat planting methods adopt the equal row spacing cultivation method, and its ventilation and light transmission effects are not good, resulting in the inability to further improve the yield. Therefore, in order to improve the wheat yield, the wide and narrow row cultivation method is gradually promoted. After wheat is harvested, a large amount of straw remains on the ground surface, especially too much wheat straw in the narrow rows. If sowing is directly carried out without manual cleaning, it is very easy to occur the phenomenon that the straw and weeds congest the seeder, causing the seeding wheel of the seeder to be suspended and unable to sow, resulting in missing seedlings and ridges.

[0003] If mechanical means are used to break up the straw and return it to the field, due to the dry weather during the harvest season, a large amount of dust is generated, affecting the air quality. And the amount of straw after returning to the field will not decrease, and there is still a large amount of straw in the ridges. The seeder will still be congested during sowing, affecting the sowing quality. Content of the Utility Model

In this embodiment, two straw distributing discs 203 are mounted on each gearbox 201, and the two straw distributing discs 203 are symmetrically arranged along the traveling direction of the frame 1. Two fourth bevel gears 209 are correspondingly mounted at the bottom of the vertical transmission shaft 205. The teeth of the fourth bevel gear 209 located above face downward, and the teeth of the fourth bevel gear 209 located below face upward, so that the two straw distributing discs 203 can rotate towards each other. The included angle between the two straw distributing discs 203 is 90°, and the conical angle formed by the two straw distributing discs 203 faces the front side of the frame 1. The two straw distributing discs 203 respectively push the straws in the ridge to both sides.
