Fertilizing and ditching device suitable for sticky and wet soil operation

Abstract

The invention discloses a fertilizing and ditching device suitable for sticky and wet soil operation, and belongs to the field of agricultural machinery. According to the fertilizing and ditching device suitable for sticky and wet soil operation, the problems that bonding and blocking occur, the working efficiency is low, and the straw stubble cutting-off capacity is weak when an existing fertilizing and ditching device of a corn no-tillage machine works in sticky and wet soil are solved. The fertilizing and ditching device suitable for sticky and wet soil operation is characterized in that the corner part of a turnover rack is hinged to the lower end of a fixing and height adjusting mechanism, a transverse plate part of the turnover rack is provided with a stretching shock absorber, the upper end of the stretching shock absorber is hinged to the fixing and height adjusting mechanism, the lower end of the stretching shock absorber is hinged to the front end of the transverse plate part of the turnover rack, and a vertical plate part of the turnover rack is provided with a fixing screw rod; an included angle is formed between the axis of the fixing screw rod and the vertical line of the vertical plate part of the turnover rack, two curved-surface opening disc furrow openers are mounted on the fixing screw rod, soil facing surfaces are attached to form a straight line, and the soil facing angle is 0 degree. The fertilizing and ditching device suitable for sticky and wet soil operation has the advantages of being small in penetrating angle, good in straw stubble cutting-off capacity, good in soil dredging capacity and soil bonding prevention capacity and significant to soil conservation farming.

Description

technical field [0001] The invention relates to a device for fertilizing and ditching, in particular to a device for fertilizing and ditching suitable for sticky-wet soil operations, and belongs to the field of agricultural machinery. Background technique [0002] Heilongjiang Province is an important major corn producing area in my country, and it is also the province with the widest distribution of black soil. Due to many years of improper cultivation mode, the loss of black land has been serious and grain production has been reduced. Therefore, in recent years, the country has actively promoted the conservation tillage mode. The corn no-tillage machine is a key equipment for conservation tillage, which can complete stubble breaking, ditching and fertilization, and sowing at one time. Multiple processes such as covering soil can effectively reduce the amount of manual work; as a key component of the corn no-tillage machine, the fertilization and ditching device can fertili...

AI Technical Summary

Problems solved by technology

Since the soil in Heilongjiang Province is relatively sticky and wet during the spring plowing period, the fertilization and ditching devices of the existing corn no-tillage machines on the market are seriously clogged and clogged, and the work performance is greatly reduced, resulting in increased soil excavation, damage to the soil layer structure, and deviation from In addition to the concept of conservation tillage, it also increases the working resistance and power consumption

[0003] There are many types of fertilization openers, but most of them cannot be guaranteed. Without lowering the requirements for agronomic fertilization, they also have the ability to prevent blockage and cut straw residues efficiently and stably in sticky and wet soils. For example, The patent with the notification number CN211580605U discloses "a kind of fertilization ditch opener". Although this type of ditch opener has a certain clay anti-blocking ability, it has a weak ability to cut straw and stubble and has poor soil breaking ability. As a result, the depth of trenching cannot meet the agronomic requirements
