Corn stubble ploughing ridging and fertilizing seeder

Abstract

The invention relates to a corn stubble ploughing ridging ridging and fertilizing seeder which comprises a rack, a speed changing box, a stubble ploughing device, a fertilizing device, a seeding device, a pressing device and a ridging device, wherein the speed changing box, the stubble ploughing device, the fertilizing device, the seeding device, the pressing device and the ridging device are sequentially arranged on the rack from left to right. The stubble ploughing device comprises a stubble ploughing knife roll connected with an output shaft on the lower portion of the speed changing box, and a stubble ploughing knife is arranged on the stubble ploughing knife roll. The fertilizing device comprises a fertilizer box and a fertilizer applying ditching device which are connected with the rack, and the bottom of the fertilizer box is provided with a fertilizer discharging device. The seedling device and the rack are connected through a parallelogram profiling mechanism, and the seedling device comprises a seed box, a seed discharging device and a seedling ditching device, and further comprises land wheels, a driving fertilizer discharging device and a seed discharging device. The pressing device comprises pressing wheels arranged on the rear portion of the seeding ditching device through a connection rack. The stubble ploughing knife, the fertilizer applying ditching device, the seeding ditching device and the pressing wheels are correspondingly arranged to form at least one group, and one set of the stubble ploughing knife, the fertilizer applying ditching device, the seeding ditching device and the suppression wheels is correspondingly arranged between every two ridging shovels.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a tractor-driven maize stubble removal, ridge fertilization, and fertilization planter capable of completing operations such as stubble removal, fertilization, precision sowing, suppression, and ridging at one time. Background technique [0002] At present, in the Northeast of my country, the corn planting mode of once a year is adopted. When sowing in spring, the corn root system and residual straw of the previous crop need to be crushed and returned to the field. The surface soil conditions are conducive to the sowing and emergence of corn. Due to the high rainfall in summer in Northeast China, ridge farming is generally used for corn planting to facilitate drainage and reduce waterlogging disasters. [0003] However, stubble cleaners, seeding and fertilizing machines, and ridging machines currently on the Northeast market can only complete one type of operation at a time, with single...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of lack of equipment, single function and low efficiency in the spring corn sowing process in Northeast China, the present invention provides a corn stubble removal, ridging and fertilizing planter, which can complete the residual root stubble crushing and returning to the field, corn fertilization, and precision seeding at one time. , Ridging and ditching and other operations can effectively improve the sowing efficiency and sowing quality, and open small furrows after sowing, without affecting the sowing depth, improve field drainage performance and prevent waterlogging disasters
