Straw returning seeder

Abstract

The invention discloses a straw returning seeder. The straw returning seeder comprises a seeder body, and a main transmission component, a stubble cleaning component, a grass cleaning component, a seed fertilizer seeding component and an earthing component installed on the seeder body, wherein the main transmission component is connected to a power shaft of the stubble cleaning component, and the power shaft of the stubble cleaning component is connected with a transmission shaft of the grass cleaning component; an output shaft of the earthing component is connected with an input shaft of the seed fertilizer seeding component; the stubble cleaning component comprises a power shaft, Y-type stubble cleaning cutters uniformly arranged on the power shaft at intervals, and a rolling and cutting cutter installed on the seeder body; the grass cleaning component comprises a transmission shaft, grass cleaning cutters uniformly arranged on the power shaft at intervals, and a grass dividing plate arranged on the seeder body; the seed fertilizer seeding component comprises a seed fertilizer box, a seed fertilizer mechanism and a furrow opener which are connected in turn; two rows of the furrow openers are arranged in a radial arrangement; a double-carrier bar is arranged on the seeder body for fixing two rows of the furrow openers. By adopting the straw returning seeder, the stubble cleaning, seeding and covering steps can be finished at one time with good crushing effect and the straw returning seeder can normally work when the sowing width is expanded to 360 cm or greater than 360 cm.

Description

technical field [0001] The invention relates to a seeder for returning straw to field and belongs to the technical field of agricultural machinery. Background technique [0002] Straw returning to the field has the following benefits: 1. Increase soil organic matter and fertilize soil fertility; 2. Form organic matter coverage to resist drought and conserve moisture; 3. Reduce the incidence of diseases and insect pests; 4. Save labor and increase production and compete for farming time; 5. Improve the soil environment , Transform low-yielding fields; 6. Optimize the environment and prevent pollution. The operating cost of mechanized straw returning is only 1 / 4 of that of manual returning, 25-35 yuan per mu, and the work efficiency can be 40-120 times higher than that of manual returning, and it can also increase production and income. Therefore, mechanized straw returning is a large-scale realization It is an effective way to cultivate land with land and establish high-yiel...

AI Technical Summary

Problems solved by technology

[0003] However, the existing straw returning equipment has the following problems: 1. The straw crushing effect is poor, especially for the upright corn straw and wheat straw with a high stubble, which cannot be directly crushed or the crushing effect is not ideal. Second, because the effect of straw returning to the field is not good enough, it will affect the sowing and fertilization, and it is easy to combine straw with soil seeds, straw rot, heat and burn seedlings, and lose moisture and fertilizer
