Small intertillage fertilizer applicator

Abstract

The invention relates to a small intertillage fertilizer applicator, belonging to the technical field of agricultural machinery. The small intertillage fertilizer applicator comprises a cultivator and an intertillage fertilizer applicator at the back end, wherein the intertillage fertilizer applicator comprises a frame, a fertilizer hopper, a depth roller, fertilizer application coulters, a ditching knife and intertillage coulters, wherein the frame is provided with the fertilizer hopper through a hopper seat, a beam at the front end of the frame is symmetrically provided with the fertilizer application coulters through a transverse sleeve and a vertical sleeve, the depth roller is arranged on the back end of the frame, the ditching knife is arranged between the fertilizer application coulter and the depth roller, and the intertillage coulters are arranged on the both sides of the ditching knife through the transverse sleeve. The small intertillage fertilizer applicator has the advantages of being compact in structure and high in working efficiency, relieving the labor intensity of the operating personnel, and avoiding the problems of large labor intensity and low working efficiency caused by manual work because the conventional large and medium-type intertillage fertilizer applicators are unsuitable for the intertillage fertilizer application work of the farmland with the smaller area. According to the small intertillage fertilizer applicator, dead angles cannot be generated in the farmland at work so as to provide convenience for users.

Description

technical field [0001] The invention relates to a fertilizer applicator, in particular to a small-scale intertillage fertilizer applicator, which belongs to the technical field of agricultural machinery. Background technique [0002] Ditching and fertilization operations in agricultural production mainly use large and medium-sized wheeled tractors as traction power to drive fertilizer applicators for fertilization operations, which not only has good fertilization effects, but also has high work efficiency. However, this method is only suitable for fertilizing operations in large-scale farmland due to the large volume of the traction machine. When fertilizing operations are carried out in farmland with a small area or narrow row spacing, it is bound to leave some working dead ends on the edge of the field. . Therefore, some farmland ditching and fertilization operations with small areas or narrow row spacing still rely on manpower to complete. Not only is the labor intensity...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a method suitable for intertillage and fertilization in farmland with small area or narrow row spacing, and the distance and depth of ditching can be adjusted, the depth of ditch is consistent, and it can be fertilized while ditching; It is a small-scale cultivating and fertilizing machine that solves the problem that the existing large and medium-sized fertilizer applicators are not suitable for ditching and fertilizing operations on farmland with a small area or narrow row spacing, and have to rely on manpower to complete. Not only the labor intensity is high, but also the work efficiency is low.
