Description
Technical field
The utility model relates to a kind of experimental rig, especially a kind of no-tillage chopper of stalk belongs to agricultural technology field.
Background technique
It is well known that major part stalk is only used as castoff burning or only as fuel at present, not only cause
The waste of natural resources, and pollute worsening environment for human survival.With the continuous improvement of level of agricultural production, farming
The yield of object stalk is increasing, therefore promotes the comprehensive utilization of stalk, not only can be reduced the waste and environmental pollution of resource, also
The output level that whole agricultural production system can be improved is the important content for realizing agricultural sustainable development.
A kind of stalk is no-tillage chopper is equipment by preceding crop chopping and returning, typical structure referring to
The Chinese patent literatures such as CN201310735328.3,201510234813.1,201510295034.2.According to the applicant understood, existing
There is no-tillage returning to the field equipment is generally existing to crush halfway disadvantage, is unfavorable for the plantation and growth of rear period crops, and complete machine
Structure is complicated, equipment is too long, increases tractor load, and it is inconvenient that field is turned round, equipment handling, operational difficulties, it is difficult to
Adapt to the various preceding stubble crops stalks such as cotton stalk, corn stover, wheat stalk.
Utility model content
The utility model aim is: being directed to above-mentioned disadvantage of the existing technology, proposes that one kind can effectively crush straw
It stalk and manipulates, transport the no-tillage chopper of convenient stalk, to be conducive to the plantation growth of succession crop, and can promote conscientiously
Using.
In order to achieve the above objectives, the no-tillage chopper basic structure of the stalk of the utility model are as follows: including front-end and back-end point
The middle and lower part of the rack not being supported on traveling wheel and pack roller, the rack is equipped with rotary-cut grinding device, and upper back is equipped with
The broken polishing apparatus being connected with rotary-cut grinding device, the broken polishing apparatus formed by the trumpet-shaped inlet towards rotary-cut grinding device with
And the rear channel throwing bend pipe and constituting, the trumpet-shaped inlet and the rear junction installation for throwing bend pipe crush and throw device, the powder
The broken device that throws has the shaft extended along conveying direction, and the rotation moving knife with stationary knife cooperation is installed in the lower part of the shaft, and
Top is installed by fan blade.
When operation, the dragger of tractor etc drives the chopper of the utility model to move ahead and overwhelm preceding stubble stalk,
When by grinding device, the stalk overwhelmed will be lifted up by rotation band and once be crushed, and then suck powder under the action of blower negative pressure
It is broken to throw device, secondary thorough crushing is carried out under the action of moving knife and stationary knife, while throwing is blown under the action of fan blade
Channel out is scattered in earth's surface.
The utility model is not only due to rationally be provided with to crush to throw device, thus stalk can be made in negative-pressure adsorption state
By secondary thorough crushing, and crushing is coaxial with blower, and structure is simple, manipulation transhipment is very convenient, while the negative pressure of blower
Pass through with can be convenient and change rotation speed regulating and controlling, to adapt to various different preceding crops.
The utility model further improves also:
The upper end of the shaft has the conical flow guiding cover of flaring.
The rotary-cut grinding device includes rotatable set axis, and the axially spaced-apart of the set axis is fixed with groups of knife two-by-two
Frame.
The inner end of the outer end hinge dress crushing knife of the knife rest, the Y-shaped bifurcated in the outer end of the crushing knife.
The spacing for axially offsetting crushing knife Y shape outer end width half of the knife rest in groups.
Two axially adjacent crushing knifes are uniformly arranged with 60 ° of the rule of being angularly sequentially staggered.
The latus rectum that bend pipe is thrown after described is tapered.

Specific embodiment
Embodiment one
The stalk of the present embodiment is no-tillage, and chopper basic structure is as depicted in figs. 1 and 2, and rack 2 can be with tow tractor
1 mounting, front-end and back-end are respectively supported on traveling wheel and pack roller 6.The middle and lower part of rack 2 is equipped with the rotary-cut of trunnion axis
Grinding device 3, and upper back is equipped with the broken polishing apparatus 5 being connected with rotary-cut grinding device 3.
The specific structure is shown in FIG. 3 for rotary-cut grinding device 3, including rotatable set axis 3-5, the both ends difference of the set axis
Through bearing support on the left and right mounting base 3-3 and 3-7 for being fixed on rack 2, axially spaced-apart is fixed with groups of two-by-two
Inner end of the outer end of knife rest 3-2, each knife rest 3-2 by pin 3-6 hinge dress crushing knife 3-4, Y-shaped point of the outer end of crushing knife 3-4
Fork.The spacing of the two Y shape outer end width half for axially offsetting crushing knife 3-4 of knife rest 3-2 in groups, to guarantee that two neighbouring crush
Knife 3-4 is able to circumferential formed and rotates overlapping projection, guarantees the good rotary-cut effect to stalk.Two axially adjacent crushing knife 3-4
To be angularly sequentially staggered, 60 ° of rule is uniformly arranged (referring to Fig. 6), experiments have shown that the rotary-cut effect arranged in this way is best.
The specific structure of broken polishing apparatus 5 is as shown in figure 4, have by the trumpet-shaped inlet 5-1 towards rotary-cut grinding device 3
And the tapered rear channel throwing bend pipe 5-2 and constituting of latus rectum, it is more advantageous to form required negative pressure in this way.Trumpet-shaped inlet 5-1 and
The junction installation for throwing bend pipe 5-2 afterwards, which crushes, throws device 4.
Crushing throws the specific structure of device 4 as shown in connection with fig. 5, has the shaft 4-2 extended along conveying direction, shaft
Blower is installed on the pairs of fan-shaped rotary moving knife 4-1 with pairs of stationary knife 4-3 cooperation, the top of shaft 4-2 respectively for the lower part installation of 4-2
Blade 4-4, and upper end has the conical flow guiding cover 4-5 of flaring, can be effectively formed negative pressure.
In work, it is stowed the no-tillage returning to the field motor spindle of stalk that the preceding stubble stalk that machine 1 overwhelms enters the present embodiment successively, when
When meeting with grinding device 3, crushing knife 3-4 crushes the stalk rotary-cut of lodging, and throws band and raise；Later, it crushes and throws device 4
The stalk that rotary-cut crushes is absorbed into channel by the negative pressure of generation, the thorough powder under the shear action of moving knife 4-1 and stationary knife 4-3
It is broken, and then blown and dish out by blower, finally it is scattered in earth's surface.It in the process, can be according to not the same stubble crop root stubble biology
The revolving speed that crushing complexity that characteristic determines etc. adjusts blower and crushing knife by current regulation button is learned, to regulate and control negative pressure
And frequency is crushed, so that the crushing of stalk is excluded effect best.
Test proves that the present embodiment structure is simple, reduces main screw lift, substantially improves the crushing of stalk and its root stubble
Effect keeps crushing more evenly thorough, is conducive to the plantation and growth of rear period crops.
