Ridge-culture minimum-tillage combined operation machine for fertilizing, sowing and corn stalk field-returning

Abstract

The present invention discloses a ridge-culture minimum-tillage combined operation machine for fertilizing, sowing and corn stalk field-returning, and belongs to the agricultural machinery. A fertilizer box with a fertilizer discharge device and a liquid decomposition agent box with a liquid pump are fixedly arranged on an upper part of a rack assembly, a straw transverse driving shaft and a rotary tillage mixing and stirring combined roll shaft are sequentially arranged on a lower part of the rack assembly from front to back, a helical blade is fixedly arranged on the straw transverse drivingshaft, a rotary tillage cutter group and a mixing and stirring rod group are fixedly arranged on the rotary tillage mixing and stirring combined roll shaft at intervals, a sealing baffle plate and aflattening compacting plate are also respectively arranged on the lower part of the rack assembly, duckbilled seed arrangement devices and compacting rollers are arranged on a rear part of the rack assembly through a seed arrangement device rack, a fertilizer discharge pipe communicates with the fertilizer box through the fertilizer discharge device, and a spray head communicates with the liquid decomposition agent box through a decomposition agent conveying pipeline and the liquid pump. The machine realizes combined operation of the fertilizing, sowing and corn stalk field-returning by a ridge-culture minimum-tillage agronomic method, and has good seedbed conditions, high fertilization and sowing quality, fast straw decomposition speed and good soil fertility-improving effect.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a multi-type combined operation machine tool for less tillage, fertilization, sowing, and corn stalk returning to the field suitable for ridge farming. Background technique [0002] Ridge farming is a traditional agricultural planting mode in the agricultural production of Northeast my country, which is cold and low temperature in northern China. Based on the many advantages of this ridge farming model, such as wind protection, drought tolerance and moisture storage, and increased ground temperature, it has always been the main planting technology of dry farming in Northeast my country, and it has not been changed or replaced. In recent years, in view of the low spring temperature, poor soil moisture, and arid climate conditions in Northeast China, which are not conducive to the actual situation of spring sowing operations, a low-tillage sowing method that minimizes disturbance of t...

Problems solved by technology

However, returning a large amount of straw to the field will cause great damage and impact on the quality of the seedbed under the less-tillage method, and the quality of the seed will drop significantly. At the same time, the effect of burying the straw after returning to the field will be poor. The effect is poor, and it is prone to diseases and insect pests, which brings many difficulties and problems to the implementation of combined operations of ridge farming, less tillage, fertilization, seeding, and straw returning to the field
