Description
Technical field
The invention belongs to agricultural machinery technological fields, and in particular to a kind of to cut a batch device for Subsoiler.
Background technique
With the development of conservation tillage, straw-returning and minimal till it is no-tillage application it is more and more extensive, and as protectiveness plough
The important link of work --- Subsoiler is also increasingly paid attention to by people, and Subsoiler can not turn over button soil, not random soil
Break plough sole under the premise of layer, it is interspersed to deep soil that the breaking of plough sole is conducive to crop root, draws deep soil
Moisture and nutrient, while being conducive to rainwater infiltration.Therefore subsoiling has crop yield, reduction rainwash and preserving soil moisture
Important meaning.
Since Subsoiler Soil Straw covers, straw blockage in front of deep soil loosing shovel will cause, this will lead to subsoiling work
The decline of industry efficiency, while will increase the tillage resistance of subsoiling, it is therefore necessary to Soil Straw is carried out before subsoiling to cut stubble processing.
The mode that current subsoiling cuts stubble is broadly divided into that broken stubble knife cuts stubble and opening disk cuts stubble, and broken stubble knife needs to export in tractor dynamic power
By straw chopping under the drive of axis, although cutting, batch effect is preferable, and meeting is broken to topsoil during cutting stubble is disturbed,
It is be easy to cause soil drifting and water erosion, is unfavorable for the soil moisture conservation of soil, simultaneously because external impetus is needed to drive, will increase energy consumption；
Opening disk carries out cutting stubble when cutting batch by the rolling of itself, although not needing external impetus, to cut batch effect undesirable, together
When opening disk encountered during cutting stubble when the hard objects such as stone it is easy to damage, operating efficiency is not high.Because the invention one kind is for deep
The high efficiency of loose operation, batch device of cutting of low energy consumption have very big application prospect.
Summary of the invention
A batch device is cut for Subsoiler the object of the present invention is to provide a kind of, which can cut off in Subsoiler
Stalk in front of deep soil loosing shovel, while it can be crushed the topsoil in front of deep soil loosing shovel in advance, therefore Subsoiler can not only be solved
The problem of straw blockage, additionally it is possible to reduce tillage resistance when Subsoiler.This cuts batch device using the adjustable allowing blade replacement of double end, makes
One times of the operating lifetime of blade；Curve is cut before batch tooth of blade sawtooth using bionical curve, it is possible to reduce resistance when cutting batch
Power；Simultaneously because the protection mechanism that leaf spring is constituted, it can make to cut a batch blade and play a protective role when encountering hard object.
The present invention is by subsoiler A and cuts a batch device B and forms, and the subsoiler A is by rack I, suspension arrangement II and subsoiling
Device III forms, and wherein rack I is made of left stringer 1, front-axle beam 2, central sill I 3, central sill II 4, right vertical beam 5 and the back rest 6, front-axle beam 2,
