Description

Large-scale corn combine
Technical field
The present invention relates to a kind of agricultural machinery, be specially a kind of large multifunctional corn combine harvester.
Background technology
At present, traditional large-scale corn combine utilizes high energy rate forging hammer pawl or flail knife to carry out crushed stalk during straw-returning, because the effect of stalk fibre tissue, the stalk after the pulverizing is the strand shape, is unwell to plough to broadcast, and load is big during operation, energy consumption is high, and efficient is low.Be poured on ground stalk and can not pick up and pulverize and can not broken root stubble rolling, be subjected to the restriction of cropping pattern, do not fit into agriculture requirement.More than many defectives seriously to having influenced applying of straw cutting apparatus.More than traditional field-returning machine do not have ensiling, packing and can function, stalk is sprinkling upon ground on the spot, do not reach the requirement of " crossing also field of abdomen " development aquaculture that country proposes, or as the requirement of work raw material.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the object of the present invention is to provide a kind of large-scale corn combine, its realization maize straw cut-out, harvesting corn fringe, stalks cutting, ensiling operation are once finished, and load is light, efficient is high, and adaptability is strong.
Technical scheme of the present invention is, large-scale corn combine, comprise engine, and be fixed on grain header on the engine, it is characterized in that, described grain header comprises that the stalk that is arranged on the frame is cut disconnected part, stalk transport portion, received the fringe part, stalks cutting part, ensiling partly, the stubble-cleaning part;
Described stalk is cut disconnected part, comprises by bearing being arranged on a cutter shaft on the frame, and cutter shaft is provided with the breaking of cutting that turns clockwise, and is provided with the small-sized branch of blade type that fixing a plurality of intervals are provided with in the place ahead of cutting breaking and holds together device;
Described stalk transport portion, be provided with the anti-down guardrail in the outside of and arranged on left and right sides in the both sides of cutting breaking, the anti-down guardrail in a plurality of inboards is fixed on the frame, its front end is that the small-sized branch of blade type holds together device, at the rear of cutting breaking is the vertical wide conveyer belt that is arranged on the band conveying tooth between two rotating shafts, the top of cutting breaking and vertical wide conveyer belt is the grain lifter that freely rotates that is arranged on the grain lifter lifting arm, and the grain lifter lifting arm is hinged on the frame, and its underpart connects grain lifter hydraulic lifting oil cylinder; Be provided with vertical transverse conveyer belt and horizontal cross conveyer belt at the rear of grain lifter and vertical wide conveyer belt, vertical transverse conveyer belt with two to three layers of conveying tooth is arranged on two rotatable shafts that are vertically set on the frame, and the horizontal cross conveyer belt is positioned at the below of vertical transverse conveyer belt; Be provided with vertical long conveying belt that band is carried tooth in the end of horizontal cross conveyer belt, vertically the top of long conveying belt is provided with the automatic adjustment compacting conveyer belt of the band compacting tooth that is provided with its gap; One loudspeaker tubular feed hopper is corresponding to the gap of adjusting automatically between compacting conveyer belt and the vertical long conveying belt;
Described receipts fringe partly is that going up of a pair of matched in clearance fed the straw wheel and fed the straw wheel down, and the corresponding loudspeaker tubular feed hopper in the slit between the two and subordinate's chopping part are provided with the corn collecting box below loudspeaker tubular feed hopper;
Described stalks cutting part, back the going up that comprises that the pair of matched that is arranged on stationary knife seat front portion is closed fed the straw wheel and fed the straw wheel down with the back, ledger-plate is fixed on the stationary knife seat and with cutoff tool and cooperates, corresponding cutoff tool and ledger-plate are provided with an opening casing, be provided with horizontal propelling auger in the casing, be provided with the straw collecting case below the discharge end of auger, the below of straw collecting case is packing or liquid filling machine;
The stubble-cleaning part is provided with rotation stubble-cleaning cutter at the middle part of frame.
The linear velocity of each tumbler is identical.
Operation principle and process are:
During large-scale corn combine operation, maize straw holds together under the device effect to divide to hold together at the small-sized branch of blade type, by cut breaking overhead 3~6cm be in maize straw is cut in advancing disconnected, pass on vertical wide conveyer belt by the power of cutting breaking rotation and the inertia of stalk own wt, prevent that by anti-down guardrail in the outside of and arranged on left and right sides and the anti-down guardrail acting in conjunction in a plurality of inboards that is positioned at the anti-down guardrail in the outside stalk is laterally askew.Stalk top is adjusted by grain lifter hydraulic lifting oil cylinder according to the height of maize straw automatically by grain lifter, and the taper that grain lifter buttresses stalk is held up backward and sent; Cutting under breaking, conveyer belt, the anti-down guardrail in the outside, inboard anti-down guardrail and the grain lifter acting in conjunction, straw is transported on the transverse onveyer, stalk is close on three V-belts, upper, middle and lower, carry under tooth and the transverse onveyer acting in conjunction by the upper, middle and lower triplex row, stalk is flowed to vertical long conveying belt.Stalk enters under the automatic adjustment compacting conveyer belt automatically, and stalk is travelled forward automatically, and stalk enters into to continue to enter in the big mouthful feed hopper and feeds the straw wheel, feeds between the straw wheel down, feeds straw up and down and takes turns fruit ear forced down and enter in the corn collecting box.Stalk moves forward to the back again and upward feeds straw wheel, back down between hello the straw wheel, and under their effect, be transported to below the ledger-plate, by under high speed rotating cutoff tool and the ledger-plate acting in conjunction with stalk on request length cut off, chopping back stalk is projected to horizontal propelling auger, stalk after will being cut off by horizontal propelling auger is transported in the straw collecting case, the stalk percentage of impurity of collecting is low, and the straw collecting case has baling press or liquid filling machine.Cutting the remaining root stubble of breaking is spread the chopping of root stubble rearward by the stubble-cleaning cutter again.
