Abstract
The utility model is related to a kind of sawing formula corn stalk shredding device, and the device is arranged on fringe and stalk harvesting type corn harvester cutting bench, there is dise knife straw chopping apparatus in the ceding of Taiwan, and sawing formula corn stalk shredding device is located at the lower section of dise knife straw chopping apparatus.Sawing formula corn stalk shredding device includes saw blade, saw blade axis, stalk support plate and support.Saw blade is rotated, and sawing crushing is carried out to maize straw bottom, and stalk supporting plate play supporting role in saw blade sawing stalk to stalk.Due to maize straw be under standing state it is chopped, therefore saw blade do not contact with soil, and the sawtooth on saw blade can effectively cut off stalk fibre all the time, improve straw-returning quality.
Description
Technical field
The application is related to a kind of corn stalk shredding device, especially a kind of sawing formula corn stalk shredding device.
Background technology
Straw-returning can increase the soil organism, and culture fertility, still, research data show, stalk whole returning to the field surpasses
The stalk amount gone out required for culture fertility, that is culture fertility need not the whole returning to the field of stalk.Meanwhile, crop-residue incorporation
It is excessive, the warm and sunny pine of soil can be caused, it is unfavorable to emerging for succession crop.Therefore can be another by a part of returning to the field of maize straw
It is partially recycled used for other purposes.
Currently, the maize straw of recovery has the roughage that significant portion is used in penkeeping.Maize straw top is aqueous
Rate is high, and degree of lignification is light, is suitable for use as roughage, on the contrary, maize straw bottom lignifying is serious, it is to be not suitable for being used as feed
's.Therefore, maize straw top can be reclaimed, stalk bottom chopping and returning.
Maize straw to it, it is necessary to crush.At present, on straw counters-field set the workpiece of crushing straw be flail knife or
Person hammers pawl into shape, and these parts are the crushing straws on the ground after stalk falls down to the ground, so flail knife or hammer pawl are inevitable
Ground is contacted with soil, and its cutting edge can wear and tear rapidly, and the effect of cutting edge cut-out stalk fibre is deteriorated rapidly, and stalk can only be rubbed into
Silk, cotton-shaped in rolling into a ball on the ground, site preparation, sowing to succession crop are adversely affected.
The content of the invention
Technology disclosed in this specification provides a kind of be arranged on fringe and stalk harvesting type corn harvester cutting bench, to corn stalk
The sawing formula corn stalk shredding device that the sawing of stalk bottom is crushed, returning to the field after the sawing of maize straw bottom is crushed.
There is dise knife straw chopping apparatus on fringe and stalk harvesting type corn harvester cutting bench, dise knife straw chopping apparatus is shredded by plucking
Reclaimed after the maize straw top that the stem pulling rod of spike body is left behind, this part straw chopping for other purposes.Sawing formula corn
Straw chopping apparatus is located at the lower section of dise knife straw chopping apparatus.
It is right under the standing state of maize straw bottom during sawing formula corn stalk shredding device chaffy corn stalk bottom
It is shredded, and saw blade does not contact soil, and saw blade sawtooth can keep sharp for a long time, can effectively cut off the fiber of stalk.
Sawing formula corn stalk shredding device disclosed in specification, including saw blade, saw blade axis, stalk support plate and support.
Saw blade is rotated, and sawing crushing is carried out to maize straw, and stalk supporting plate plays supporting during saw blade cutting stalk to stalk
Effect.
The beneficial effects of the invention are as follows the liftoff chopping for realizing maize straw, stalk fibre is effectively cut off, stalk is improved also
Field quality.

Embodiment
Such as Fig. 1, sawing formula corn stalk shredding device is arranged on the bottom of fringe and stalk harvesting type corn harvester cutting bench, its
Top is the housing (7) of dise knife straw chopping apparatus (not shown in accompanying drawing).Dise knife shredding mechanism is responsible for chopping by corn snapping unit
The maize straw top left behind of stem pulling rod, reclaim after this part straw chopping.
Such as Fig. 1, Fig. 3, coaxially, two axles are with shaft coupling (4) for the dise knife axle (3) of saw blade axis (2) and dise knife straw chopping apparatus
It is coupled, the lower end of saw blade axis (2) is supported on support (8) by thrust ball bearing (10).Shred and fill with dise knife in support (8) upper end
The housing (7) put is connected.
The different saw blade of multiple diameters is installed on such as Fig. 1, Fig. 4, the saw blade axis (2) of sawing formula corn stalk shredding device
(1), saw blade diameter is sequentially reduced from top to bottom, in back taper, is separated between saw blade with axle sleeve (6).
There is the shaft shoulder (9) on such as Fig. 1, Fig. 3, saw blade axis (2).More than support (8) saw blade is by tightening nut (5) by saw blade
The shaft shoulder (9) is pressed to axle sleeve and is fixed.The following saw blade of support (8) and sleeve (13) are fixed with hexagon slotted nut (12), and six
After angle slotted nut (12) is screwed, pin (11) is inserted into the radial hole of saw blade axis (2) end, makes hexagon slotted nut (12)
Locking.
Such as Fig. 1, Fig. 3, the lower end of sleeve (13) is welded with a piece of saw blade, and the bottom of such whole device is exactly this blade saw
Piece, rather than saw blade axis (2) bottom and hexagon slotted nut (12), can so prevent that saw blade axis (2) and hexagonal from slotting spiral shell
Female (12) bump against the corn stubble not got off by saw blade sawing, and saw cutting device is damaged.
Such as Fig. 1, the diameter of saw blade is sequentially reduced from the top down.During sawing stalk, sawed first by the big saw blade of upper diameter
Cut, finally by the small saw blade sawing of lower diameter, can so prevent from, because stalk is leaned forward by saw blade thrust, sawing above
When piece is also without complete sawed-off stalk, lower blade alreadyes switch off stalk, stalk is lost root support, causes saw blade above
Finally can not completely sawed-off stalk.In saw blade sawing stalk, stalk is not only leaned forward by thrust, and is acted on by sawing force,
Stalk will also topple over along saw blade direction of rotation (16), cause stalk completely sawed-off, therefore the saw that the present apparatus is swung in stalk
Piece side is mounted with stalk supporting plate (15).Stalk supporting plate (15) is so installed：First angle steel is welded on support (8)
(14) stalk supporting plate (15), is then welded on angle steel.
During operation, the power of maize harvesting machine engine (not shown in accompanying drawing) by actuating unit (in accompanying drawing not
Show) dise knife axle (3) is delivered to, then saw blade axis (2) is delivered to through shaft coupling (4), saw blade axis (2) drives saw blade (1) rotating saw
Cut maize straw (17), returning to the field after stalk sawing is crushed.
Protection scope of the present invention not limited to this, skill of any one skilled in the art in present disclosure
In the range of art, the simple change or equivalence replacement of the technical scheme that easy can be obtained each fall within protection scope of the present invention
It is interior.
