Wheat wide-width uniform sowing device with controllable sowing depth

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a wheat wide-width uniform sowing device with the controllable sowing depth. A pair of suspension supports arefixedly installed on a rack, a sowing supporting transverse frame is arranged between the two suspension supports, and the two suspension supports are connected with the left end and the right end ofthe sowing supporting transverse frame in a suspended manner through lifting adjusting assemblies; a plurality of sets of sowing pipe groups which are arranged at equal intervals in the length direction of the sowing supporting transverse frame are arranged on the sowing supporting transverse frame, and front sowing pipes and rear sowing pipes of each set of sowing pipe groups are arranged alternatively; each sowing pipe comprises a vertical part, a circular arc part and a circular arc steel plate, wherein the circular arc part is bent backwards, and the circular arc steel plate is centrally welded on the lower side of the inner wall of the circular arc part in the section direction of the circular arc part; and the lowermost end of each arc steel plate corresponds to the lowermost end ofthe corresponding arc part and is provided with a tail end tilting part extending out of the lowermost end of the arc part, and each tail end tilting part warps upwards relative to a corresponding arcsteel plate body. According to the wheat wide-width uniform sowing device, the technical indexes such as sowing depth consistency, sowing uniformity and different soil adaptability are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a wide-width uniform sowing device for wheat. Background technique [0002] The amount of crop straw produced in my country is about 1 billion tons every year, accounting for nearly 20% of the global total. It is a technical, ecological and social problem to be solved urgently without burning straw and making economical and effective resource utilization. At present, the "full amount of hard stubble land" where the previous crops such as rice are harvested without any collection and removal of straw has become the new normal of farming in my country. [0003] The applicant has disclosed the invention patent "A No-Till Seeder for Straw Crushing Inter-Row Collecting and Covering", and the application number is 2018108613806. The planter is mainly composed of a frame, a straw crushing and cleaning device (including a broken straw diversion device), a fertilization de...

AI Technical Summary

Problems solved by technology

However, the wheat wide uniform sowing device disclosed in the prior art still needs to be improved in terms of controllable sowing depth and sowing uniformity.
