Description
The present invention is the improvement to tillage-free mulcher sowing workpiece.
The key of tillage-free mulcher is the no-tillage seeding machine workpiece, generally comprises breaking ridge buster (1), double disk opener (2), grain conductor (3), suppression of soil wheel (4) and parallel four-bar profiling support parts such as (5).
The effect of breaking ridge buster is separately (or cut-out) straw, stubble and chesson, provides suitable kind bed to seed, and existing sower all adopts disk knife breaking ridge buster, and as flute profile disk, ripple disk etc., its operation principle is that gravity is cut stubble.Though its wide adaptability, be difficult for dragging heap, must there be enough weight could cut off straw and stubble, if can't cut, seed will be broadcast on the straw that is pressed into by disk in the seed furrow, can not contact with subsoil, influence is emerged.Therefore, not only the material of cutting disc is required highly, and each cutting disc need add counterweight 180-270 kilogram, connects the no-tillage cover-seeding of stubble if be used for continuous cropping then, and breeding then needs bigger, otherwise stubble straw before can't cutting off.This just requires sower that enough strength and stiffness must be arranged, and generally mostly is towed, and consumptive material is many, and structure is huge and heavy, operation inconvenience, and traction power is big, and this breaking ridge buster can't be executed seed manure simultaneously.
Double disk opener generally adopts the staight shank mode to be connected with parallel four-bar profiling support.
Existing grain conductor generally all only adapts to mechanical type or air-sweeping type seeding unit, and this seeding unit has a common feature, is exactly that its direction of charging seed is vertical or is tilted to down, is easier to contact with grain conductor in tangent mode.
Huge in order to overcome existing tillage-free mulcher working part structure, heaviness can not be executed seed manure, and grain conductor can not adapt to shortcomings such as air-sucking type seeding.To the breaking ridge buster of sowing workpiece, grain conductor improves, and according to leading the needs of planting, the connected mode of double disk opener is changed into oblique handle by the staight shank connection connect.
The present invention has adopted a kind of novel breaking ridge buster one scalpriform breaking ridge buster, by stubble breaking knife (6), divide careless plate (7) and breaking cutter head (10) to form, when executing seed manure as needs, the breaking ridge buster also should comprise fertilizer-guiding plate (9) and the fertilizer guiding tube (8) that is positioned at the careless backboard face of branch.The operation principle of scalpriform breaking ridge buster is that thrust is divided stubble.Cutter wall forward position and ground are acute angle, and penetration performance is good, do not need to add in addition counterweight.Again because of penetrating angle less than the angle of friction between straw and the breaking cutter head, in the course of the work, the effect that straw is subjected to forward thrust and ground holding power moves past in the journey last along sliding (accompanying drawing 3) on the inclined-plane, straw can break away to one along minute careless plate.So scalpriform breaking ridge buster is dredged the straw of broadcasting on the row by moving on the straw and the sideslip effect, makes it branch to both sides, has avoided the difficulty of powerful cut-out, thereby finish the operation of breaking ridge buster.
The top edge of a knife of scalpriform breaking ridge buster adopts circular arc, in case hang grass, the both sides of the part of burying divide that careless plate is narrower then to be bordering on parallelly, and to reduce resistance, it is cumulative big that the both sides of acrial part divide careless plate holder to contend, and is convenient to slide the branch grass.Dividing the both sides, top of careless plate is asymmetric shape, and the careless plate of anisopleural branch extremely helps sideslip and divides grass.Divide between the careless plate in both sides to have added fertilizer guiding tube, execute the needs of seed manure in the time of can satisfying sowing simultaneously.
The function of double disk opener is in water furrow planting, a spot of return straw to be divided to both sides, generally by two disks (15), oblique handle (14), crosswise fixed plate (13) formation.The place that is different from existing sower is staight shank to be connected change oblique handle connection.Its objective is position and installation grain conductor in order to adapt to seeding unit, the oblique handle of plough leaves 40 ° on plumb line forward, and the accumulation height is 67mm.
Grain conductor used in the present invention is by straight transitions section (16) and curve boot segment (17) be combined into, and it has following several characteristics.(1), except being applicable to the seeding unit that tangential direction charges seed, also be applicable to air-suction seeding unit (it charges seed the direction level backward, and certain lateral movement is arranged).(2), since seed when leaving seed plate to a lateral movement, cause its inlet center must depart from seed plate side certain distance thereupon, thereby in grain conductor, also guide with camber line.(3), the curve shape of leading kind is with generally grain conductor is different, it has the characteristics of space curve in two planes curvature being arranged all in length and breadth.Fig. 6 is the motion diagram of seed under the sower duty, in fore-and-aft plane, when seed glides along this path, gets according to the law of conservation of mechanical energy:
Mgy-1/2mv
2 0=1/2mv
2+ ∫
X 0Fmgcos α ds ... (1) wherein cos α=dx/ds f is a coefficient of friction, and mg is a constant.
Differentiate is put in order promptly: Vdv=gdy-fgdx ... (2)
Solve an equation (2):
V＝V
2 0－2g（y－fx） …………（3）
This is the equation of seed speed the during optional position in grain conductor.
In Fig. 6 middle and upper part is straightway, and it and horizontal sextant angle are 70 °, and the bottom is a curved section, and its equation is as follows:
Wherein a is the spinning roller diameter, and ο is the corner of spinning roller in curved section.
Variously can try to achieve speed and the angle of seed when leaving grain conductor by above.As calculated, the horizontal component of this speed is about 6 kilometers/hour, and is close with the sower pace, makes on the final level direction and charges seed for zero velocity.
The suppression of soil wheel adopts " V " type press wheel, and its effect is earthing, suppression, limit is dark and profiling.The pinch roller diameter is about 300mm, and the pinch roller width is about 30mm, and pinch roller and ground are 20 degree angles, and two pinch rollers can be regulated in the 20-40mm scope according to soil regime and scalpriform ridge buster width etc. in the inboard at ground connection place distance.
More than each parts be fixed on the after-poppet of parallel four-bar frame, after-poppet is provided with cutter hoop, eyelet seat and screw etc., in order to fixedly breaking ridge buster, double disk opener and seeding unit, the suppression of soil wheel then is fixed on the seeding unit by tailstock respectively.Grain conductor is fixed in the pipe collar on the oblique handle of double disk opener.Each part mentioned above is organically linked together, promptly constitute the complete no-tillage cover-seeding workpiece of a cover.
The bury relative position relation (Fig. 8) of part of whole no-tillage workpiece is: the darkest with scalpriform breaking ridge buster incision soil, disk coulter takes second place, and the left and right wheels of press wheel inwardly is pressed into soil, to realize the function of suppression of soil.
This workpiece has simple in structure, and is in light weight, can execute seed manure, realizes that continuous cropping then connects the no-tillage cover-seeding of stubble; Sowing is even, and the depth is suitable, and it is little to broadcast back ditch shape; Under the more situation of straw, also can realize normal sowing, do not drag, pile, block up characteristics such as grass.
