A shunt-guided uniform throwing device that realizes large-scale and wide coverage of straw and returns it to the field

Abstract

The invention relates to a shunt-guided uniform throwing device that realizes straw covering and returning to the field with a large width. On the left and right sides of the outlet of the shredded straw throwing pipeline, a pair of guide channels that are inclined to the left and right sides are arranged; A pair of impellers are installed at the outlet of the straw throwing pipeline, and each impeller corresponds to one of the guide channels and is located in the direction in which the guide channels extend outward; Sprinkle afterwards. In the present invention, through the shunting and guiding functions of the diversion guide plate and the outer guide and guard plate of the shredded straw throwing port, the shredded straw hits the left-rotating impeller assembly and the right-rotating impeller assembly respectively, and the two impeller assemblies are free to rotate outward under force, and the shredded straw Throwing and covering to both sides respectively, to realize evenly spreading of straw in a wide width, covering and returning to the field.

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
