Combined type sowing fertilizing ditcher

Abstract

The invention provides a combined type sowing fertilizing ditcher and belongs to the technical field of agricultural machinery. The left end of a scraping plate is fixedly connected with a sowing ditcher bank in a core ploughshare type ditcher and the right end of the scraping plate is fixedly connected with a side of a connecting plate base in a notch disc ditcher, so that the core ploughshare type ditcher and the notch disc ditcher are integrally combined. The combined type sowing fertilizing ditcher can solve the problem that a hard soil layer is difficult to ditch during an inter-row sowing process; the core ploughshare type ditcher and the notch disc ditcher are used in a matching form, so that the positive pressure required by the notch disc ditcher for penetrating into the soil is reduced and the problem of difficulty in controlling the soil-penetration depth when the core ploughshare type ditcher is singly used is solved; and the combined type sowing fertilizing ditcher has excellent soil-penetration property and strong passing capacity.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a combined sowing and fertilizing ditch opener. Background technique [0002] Most of the mechanized operations in Northeast China are planting on uniform ridges. In order to realize the recycling of farmland straw and protective tillage, it is required to change the planting on the ridges from year to year to alternate planting between rows. The inter-row interaction conservation tillage mode is one of the key conservation tillage modes implemented in Jilin Province, that is, the corn stubble from the previous year is kept on the surface and planted between two stubble rows, and the planting row and the stubble row each year Swap once for alternate planting. [0003] The research on no-tillage seeders in our country started relatively late. Due to various reasons such as planting methods, land conditions and economic development, foreign no-tillage se...

AI Technical Summary

Problems solved by technology

The combined use of the disc opener and the core share opener can reduce the positive pressure required for the notched disc opener to enter the soil, and overcome the problem that the depth of the core share opener is not easy to control when the core share opener is used alone. Type trench opener has good soil penetration performance and strong passing ability
