Sowing machine capable of carrying out compacting, reverse rotation, ditching and fertilizing before rotary tillage and straw breaking and working method thereof

Abstract

The invention relates to a rice and wheat sowing machine capable of carrying out compacting, reverse rotation, ditching, sowing and fertilizing before rotary tillage and straw breaking sowing. The sowing machine structurally comprises a rack, a soil retaining cover, a reverse-rotating cultivator, a pre-sowing compacting roller, a speed measuring wheel, a double-disc ditcher, a single-hinge profiling compacting mechanism, a double-fertilizer box, a seed box, a reverse-rotating ditching cutter and a ditch protection device. The sowing machine has the advantages that (1) on the basis of meeting the agronomic requirements, the procedures of fertilizing, rotary tillage, straw crushing, ditching, sowing and compacting are completed in field operation at one time, so that the frequency of field operation based on machinery is decreased, and the operation cost is reduced; (2) the pre-sowing compacting roller is arranged for compacting before sowing, the sowing depth can be thus controlled moreeffectively and precisely, and seed emergence and development are facilitated.

Description

technical field [0001] The invention relates to a rice and wheat planter for suppressing and counter-rotating ditching, fertilizing, sowing and fertilizing before sowing by rotary tillage and broken rods, and a working method thereof, belonging to the technical field of agricultural machinery. Background technique [0002] Rice and wheat are the main crops in my country, and the planting area and total output account for 70% of the country's total grain output. Jiangsu Province is a typical "rice-wheat" area with two crops a year. The rice and wheat planting area is about 26 million mu, accounting for more than 40% of the province's arable land area. In recent years, problems such as the shortage of labor resources and the short time for rice-wheat rotation have become prominent. The production efficiency of manual operations is low and the cost is gradually increasing. However, the fields in Jiangsu are generally small and there is sufficient rainfall all year round.

AI Technical Summary

Problems solved by technology

In recent years, problems such as the shortage of labor resources and the short time for rice-wheat rotation have become prominent. The production efficiency of manual operations is low and the cost is gradually increasing. However, the fields in Jiangsu are generally small and there is sufficient rainfall all year round. Coupled with unreasonable farming methods, the soil is seriously wet and sticky, and it is difficult for operating machinery to walk in the field. The perennial shallow rotation replaces deep plowing, resulting in low porosity, shallow plowing layer, and soil hardening, which affects the efficient operation of the seeder, resulting in Problems such as soil compaction and high power consumption of plowing to return to the field are prominent

And the general steps of wheat planting in this area are: straw plowing and returning to the field-rotary plowing and leveling-draining and ditching before sowing-base fertilizer application-drill sowing-post- sowing suppression, but the existing traditional seeders have simple functions and a single structure. Multi-process integrated compound operations cannot be carried out, which increases the cost of planting operations

[0003] The problem that needs to be solved urgently at present is that the crushing degree of straw is lower than the national standard, and the crushing degree is not below 10 cm;
