Shunting, guiding and uniform scattering device for realizing large-breadth-coverage returning of straw

Abstract

The invention relates to a shunting, guiding and uniform scattering device for realizing large-breadth-coverage returning of straw. A pair of guiding channels for obliquely guiding towards the left side and the right side is arranged on the left side and the right side of an outlet part of a straw crushing throwing pipeline; a pair of impellers is mounted at the outlet part of the straw crushing throwing pipeline, and each impeller corresponds to one of the guiding channels and is positioned in the outward extending direction of the guide channel; and the impellers rotate towards the outer side, so that the crushed straw is thrown backwards in large breadth. Through the shunting and guiding effects of a shunting guide plate and a guide protection plate on the outer side of a straw crushingthrowing opening, crushed straw impacts a left rotary impeller assembly and a right rotary impeller assembly correspondingly, the two impeller assemblies are stressed to freely rotate outwards to scatter and cover the crushed straw towards the two sides correspondingly, and large-breadth uniform scattering and covering returning of the straw are achieved.

Description

technical field [0001] The invention relates to equipment for fertilizing, sowing, sowing, and covering straw with crushed straw, in particular to a shunt-guiding uniform throwing device for realizing large-scale and wide coverage of straw and returning it to the field. Background technique [0002] Returning full amount of straw to the field as fertilizer is an effective way and main direction of comprehensive utilization of straw in my country at present; crop straw is not removed or burned, and full amount of straw is returned to the field for utilization has become a common choice of farmers; Do any collection, removal, processing, and return the full amount of farmland to be sown, that is, "full amount of straw field" has become a normalized farming situation in my country. [0003] The publication date is January 23, 2013. The Chinese patent document with the publication number CN102884888A discloses "A Multifunctional Unit for Shredding, Straw Clearing, Fertilization, ...

Problems solved by technology

[0004] However, in order to improve productivity and adapt to the requirements of large-scale planting production, as well as the rapid growth of the number of high-horsepower tractors in recent years, with the production, popularization and application of multifunctional units with a working width of 2200mm, 2400mm, and 2900mm, the existing The technology has the disadvantage of not being able to spread straw evenly in a wide width and cover it to the field, resulting in the lack of seedlings and weak seedlings of the crops due to the inability to cover the straw in full width and width and uneven coverage after large-scale and wide-width efficient mechanized sowing operations
