Single-row seedling strip tillage and preparation combined machine in straw row-returning mode

Abstract

The invention provides a single-row seedling strip tillage and preparation combined machine in a straw row-returning mode. The single-row seedling strip tillage and preparation combined machine comprises a rack, a gearbox, a rotary tillage shaft, a large chain wheel, a small chain wheel, a chain wheel transmission shaft, a spline transmission shaft, a soil pressing plate, a pressure spring rod, apressure spring, a pressing roller, a pressing roller bearing pedestal, rotary blades, roller chains, chain wheel covers, land wheels, lower suspension rods, upper suspension rods, pressing roller connecting rods and the like. The machine can perform rotary tillage operation on a seedling strip under the condition of returning all straws to the field and returning the straws to rows, so that surface hardened soil is improved, the ground temperature is increased, and the water retention capacity of soil is improved. The single-row seedling strip tillage and preparation combined machine is a breakthrough of a protective tillage whole-process mechanization technology.

Description

technical field [0001] The invention belongs to the technical field of corn protective tillage mechanization, and relates to a device for performing rotary tillage on seedling strips on the ground surface except for straw-covered areas before planting. Background technique [0002] In recent years, the area of ​​corn planted with conservation tillage technology in my country has continued to increase, and the area of ​​straw recycling technology has been continuously expanded and applied. However, there are still certain unfavorable conditions for straw recycling technology. It is carried out under the premise of not moving the soil. Although it has a certain protective effect on the soil, the soil has been severely compacted after many years of machine tools entering the ground, which is not conducive to the rapid entry of water into the soil. The soil is not loose enough, which is not conducive to gas exchange. The ground temperature is higher than that of traditional ridge ...

[0002] In recent years, the area of ​​corn planted with conservation tillage technology in my country has continued to increase, and the area of ​​straw recycling technology has been continuously expanded and applied. However, there are still certain unfavorable conditions for straw recycling technology. It is carried out under the premise of not moving the soil. Although it has a certain protective effect on the soil, the soil has been severely compacted after many years of machine tools entering the ground, which is not conducive to the rapid entry of water into the soil. The soil is not loose enough, which is not conducive to gas exchange. The ground temperature is higher than that of traditional ridge farming rise slowly

Some farmers not only hope to adopt the technology of conservation tillage straw return, but also hope to retain the favorable conditions of traditional ridge farming. However, when the full amount of straw is returned to the field, traditional soil preparation machines cannot meet the operation requirements.
