Problems solved by technology

However, the above-mentioned patents are difficult to solve the problems of uneven mixing of soil and straw and easy congestion due to the large amount of straw returned to the field, and lack of precise and intelligent proportional layered fertilization devices and wide seedling width with high seed uniformity. The drill device is difficult to meet the needs of large grain growers for multi-functional soil preparation, fertilization and sowing integrated machinery in the intensive, large-scale and standardized production of grain crops

Abstract

The invention relates to a broad-seedling-width precision sowing machine with functions of double rotary tillage and proportional layering fertilization. The precision sowing machine comprises a suspended rack, a gearbox, a double-shaft rotary tillage device assembly, an anti-jamming spiral land leveler, a proportional layering fertilization device assembly, a rolling cage harrow, a broad-seedling-width strip sowing device assembly, a cylindrical heavy roller, and a proportional layering fertilization and precision sowing intelligent control system; and the precision sowing machine can sequentially finish operations in links of double rotary tillage for land preparation, spiral blade land leveling for jamming prevention, proportional layering fertilization, land leveling and rolling before sowing, broad-seedling-width precision sowing, rolling after sowing and the like in one time. According to the precision sowing machine, the broad-seedling-width sowing can be realized and a twice throwing and unique multilayer comb strip decentralizing and seed uniformizing structure is adopted, so that seeds can be uniformly distributed in a relatively broad seedling width (8-10cm) range and the space layout structure of seedlings is remarkably improved; and the relationship between a group and an individual is coordinated and a reasonable crop group is created, so that a solid foundation is laid for high yield.

Description

[0001] (1) Technical field [0002] The invention relates to a double rotary tillage and proportional layered fertilization wide seedling width precision seeder, which belongs to the field of agricultural machinery and equipment and is suitable for double rotary tillage soil preparation, proportional layered fertilization and wide seedlings for wheat, barley and other wheat crops Integrated operation of width drill and planting. [0003] (2) Technical background [0004] Wheat-corn multiple crop rotation is an important planting mode in the Huanghuai and northern winter wheat regions of my country, and plays an extremely important role in ensuring national food security. Returning wheat and corn stalks to the field is an important technical measure to improve soil fertility, improve soil physical structure, and increase grain production in this area. However, in the current production, corn stalks are mostly returned to the field in full, and the amount of straw is generally l...
