Drought-resistant stubble-cleaning deep-seeding fertilization machine for wheat stubble soil planted corn

Abstract

The invention relates to a drought-resistant stubble-cleaning deep-seeding fertilization machine for wheat stubble soil planted corn, which comprises a rack, as well as depth limiting wheels, a seeding belt stubble-cleaning soil-cleaning device, ditching fertilizer applicators, soil compactors, corn single-kernel dibbling devices and seeding compacting wheels, which are sequentially arranged on the rack from front to rear. The two depth limiting wheels are fixed at the left end and right end of a front cross beam of the rack; the seeding belt stubble-cleaning soil-cleaning device comprises a stubble-cleaning soil-cleaning cutter shaft, stubble-cleaning soil-cleaning cutter discs and stubble-cleaning soil-cleaning cutters; multiple stubble-cleaning soil-cleaning cutters are circumferentially arranged on each of the inner disc surface and outer disc surface of each stubble-cleaning soil-cleaning cutter disc; each stubble-cleaning soil-cleaning cutter comprises a handle part and a throwing cutting part, with an included angle of 100-120 DEG C formed between the handle part and the throwing cutting part; the throwing cutting parts of the stubble-cleaning soil-cleaning cutters on the inner disc surface of each stubble-cleaning soil-cleaning cutter disc are bent inwards, and the throwing cutting parts of the stubble-cleaning soil-cleaning cutters on the outer disc surface of each stubble-cleaning soil-cleaning cutter disc are bent outwards. The drought-resistant stubble-cleaning deep-seeding fertilization machine for wheat stubble soil planted corn provides integrated operation of soil tillage, seeding, fertilization and compaction, the operation steps are simplified, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an integrated machine for drought resistance, stubble clearing, deep sowing and fertilization of wheat stubble and corn. Background technique [0002] The winter wheat-summer maize rotation is one of the main planting methods of food crops in North China, which contributes 48% and 39% of my country's wheat and maize production respectively, and plays a pivotal role in ensuring national food security. In the current winter wheat-summer maize rotation system, after the winter wheat is harvested, summer maize is generally sown between the wheat rows without soil preparation in order to sow in a timely manner. However, it is very difficult to accurately sow corn between wheat rows due to factors such as wheat straw stubble, machine hand operation, uneven ground, and mechanical operation rolling. However, if the seeds are sown on wheat stubble or wheat stra...

AI Technical Summary

Problems solved by technology

[0004] In view of the current winter wheat-summer corn rotation system in North China, the root stubble of wheat straw in the previous crop has a great impact on the quality of corn sowing and emergence, especially the impact on single-grain precision-sowed corn is more serious, and the soil surface moisture is often insufficient when wheat is harvested, etc. At the same time, there are problems such as separate operations and complicated procedures in the existing technical links such as corn soil preparation, fertilization, and sowing. The purpose of the present invention is to provide an integrated machine for wheat stubble corn drought resistance, stubble clearing, deep sowing and fertilization.
