Suspended type urgent-need fertilization furrow opener

Abstract

The invention discloses a suspended type urgent-need fertilization furrow opener, which comprises a support plate, wherein the front surface of the support plate is provided with a triangular fixing frame; the middle part of the triangular fixing frame is provided with a reinforcing rib; the lower surface of the triangular fixing frame is provided with a first supporting column; the lower side ofthe front surface of the first supporting column is provided with a groove; a universal wheel is arranged inside the groove; the universal wheel is rotationally connected with the first supporting column through a rotating shaft; the lower surface of the support plate is provided with two hydraulic telescopic rods; the telescopic end of each hydraulic telescopic rod is fixedly connected with a moving plate; the lower surface of the moving plate is provided with three second supporting columns; the three second supporting columns are in left and right corresponding arrangement. The suspended type urgent-need fertilization furrow opener has the advantages that the structure is firm and durable; the suspended type urgent-need fertilization furrow opener can be suspended; convenience is brought for outgoing and use; the furrowing resistance is small; the hard soil layer is cut open; the soil perturbation is little; the tilling depth stability is good; the agronomic requirement of precise and little fertilization operation of intertillage or no-tillage land can be met; the fertilizer utilization rate can be improved.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a hanging type emergency fertilization ditch opener. Background technique [0002] The fertilization ditch opener is the key operating part of the intertillage fertilization, seeding and fertilization machinery. During the fertilizer application process, the fertilizer ditch is opened through the fertilization ditch opener. The fertilizer is scattered and distributed in the ditch through the fertilizer guide pipe, and then covered with soil. Currently, the production Widely used ditch openers mainly include shovel type, disc type and sliding knife type. When the shovel type ditch opener is working, the soil is turned up, and the dry and wet soil are mixed, which is not conducive to moisture conservation, and when there are many debris in the field, it is easy to cause congestion. Soil, entangled grass, clogging phenomenon, unstable working quality, suitable for use...

[0002] The fertilization ditch opener is the key operating part of the intertillage fertilization, seeding and fertilization machinery. During the fertilizer application process, the fertilizer ditch is opened through the fertilization ditch opener. The fertilizer is scattered and distributed in the ditch through the fertilizer guide pipe, and then covered with soil. Currently, the production Widely used ditch openers mainly include shovel type, disc type and sliding knife type. When the shovel type ditch opener is working, the soil is turned up, and the dry and wet soil are mixed, which is not conducive to moisture conservation, and when there are many debris in the field, it is easy to cause congestion. Soil, entangled grass, clogging phenomenon, unstable working quality, suitable for use in areas with good soil preparation, less surface debris and good soil moisture; disc and sliding knife openers require large vertical loads, and the machines are heavy , suitable for the use of large machines. At present, the surface soil is relatively hard during fertilization on intertillage or no-tillage land, and there are residual stems, stubble or weeds, which reduces the passing capacity of the opener and increases the working resistance of the opener. At the same time, the new agronomy of lateral and deep application of chemical fertilizers also puts forward higher requirements for the amount of fertilizer applied, the width and position of the fertilizer belt, and the scattered fertilizers in the fertilizer ditch are not conducive to improving the utilization rate of fertilizers.
