Description

Self-propelled wheat straw harvesting and bundling up machine

Technical field: the utility model relates to agricultural machinery, is meant that a kind of wheat stubble straw receives the mow binder tool of usefulness again.

Background technology: at present, adopt the combine getting wheat, it is very high that wheat stubble stays, and is not easy to the crop sowing of following season, adopts the stubble-cleaning of burning the grass on waste land, and not only wastes resource, and contaminated environment has also been destroyed upper soll layer nutrient and structure, has killed edaphon; And the wheat stubble that cuts has influenced the combine threshing performance again when short greatly, and many wheats are discharged with wheat straw, waste grain, and existing a kind of fixing vertical straw grass binder, but it can not cut a batch limit bundling on the limit, field.The applicant in first to file, application number is 01276705, be that header with combine places the tractor front end, to have straw grass binder and be fixed in the tractor rear end, constitute a novel wheat straw harvesting and bundling up machine, realize that the stubble-cleaning of high wheat stubble cuts bundle, but it has weak point, be that its whole structure equipment is unreasonable, make turning dumb, influenced production efficiency.

Summary of the invention: technical problem to be solved in the utility model, be to fill up the blank of prior art, remedy deficiency in first to file, transform former tractor as front-wheel drive, rear-axle steering, engine place on the chassis frame of middle part, and the combining platform places chassis front end, straw grass binder places on the vehicle frame of back, constitutes a self-propelled wheat straw harvesting and bundling up machine.

Structure of the present utility model is, it comprises combining platform and straw grass binder, also comprises engine and chassis, and engine places on the middle carriage of chassis, and header places chassis front end, and binder places on the vehicle frame of rear portion, chassis;

Described chassis comprises pre-driver wheel 28 and rear steering wheel 29; By engine one end power output wheel 35, through bel-drivenn driven pulley 36, wheel shaft 37, driven pulley 38,39, and clutch, gearbox and vehicle bridge constitute the walking power train; Constituting walking by the pitman arm of direction machine 40, longitudinal tie 41, steered wheel 29 and the axle differential etc. that drives wheel 28 turns to and is;

Engine other end power output wheel 32, constitute the binder transmission devices through bel-drivenn driven pulley 33, speed changer 34, driving gear 11 and the driven gear that is meshed with it 10.

Advantage of the present utility model is owing to drive wheel preceding, steered wheel after, and strengthened the front and back wheel wheelspan, engine and binder place, on the rear chassis vehicle frame, make its whole structure equipment scientific and reasonable, center of gravity is between the front and back wheel, front and back counterweight equilibrium, and car load turns to flexibly; Before and after connect existing header and straw grass binder, it is effective to cut bundle, the efficient height.

Description of drawings: accompanying drawing 1 the utility model front view

Accompanying drawing 2 the utility model rearviews

Accompanying drawing 3 the utility model vertical views

Embodiment: the present invention's structure is shown in accompanying drawing 1,2,3, and complete machine can divide three parts, and the front portion is divided into the header of existing combine, and the rear portion is divided into existing horizontal piston bale binder, and mid portion is transmission and running gear.Middle transmission and running gear can newly be made by accompanying drawing, also available tractor converts, the utility model is that 195 tractor with small four wheels butts are reequiped with tail, with front axle, front-wheel postposition, and change 195 engines into 295 engines, place vehicle frame top between two wheels, engine power output, both as walking power, again as binder power.

Concrete structure is: tractor with small four wheels is shed diesel engine, direction machine front portion is cut off, keep direction machine 40, clutch, speed changer, clutch pedal 42, kill car pedal 43, back axle, trailing wheel become propons, the front driving wheel 28 of new car, former front axle, front-wheel postposition, become deflecting roller 29 behind the new car, and distance between two wheels before and after the lengthening, direction machine longitudinal tie 41 is connected the pitman arm (not shown) of deflecting rollers 29.Binder base plate 6 its front ends 27 are fixed on the former rear axle shaft 26, and the double as chassis frame is fixed on steered wheel 29 wheel shafts at its middle part.Engine 30 places vehicle frame top between two wheels, the power output wheel 35 of one end, through bel-drivenn driven pulley 36, wheel shaft 37, driven pulley 38,39, and clutch, gearbox and former back axle constitute this machine walking power train; By the pitman arm of direction machine 40, longitudinal tie 41, steered wheel 29 and drive this machine that the former rear axle differential etc. of wheel 28 constitutes and turn to and be; The power output wheel 32 of the engine other end behind clutch 31, through bel-drivenn driven pulley 33, speed changer 34, driving gear 11 and the driven gear 10 that is meshed with it, and bent axle 9, piston rod 8 constitute the binder power trains.

The combining platform comprises parts such as dialing-grain unit 1, scissors 2, feeding cylinder 3, defeated standing grain device 4, hydraulic lift hitch, transmission, fixedly card 5 by the vehicle frame front end is affixed with header dead lever 44, the wheat stubble straw grass of harvesting is through defeated standing grain device---and the material guiding hopper (not shown) adds bundling case feeding mouth 24, also can establish the frid (not shown) that connects material on one side in binder, the people stands on it, and the material that falls is dialled in feeding mouth 24.Driving gear 11 its axle heads are installed a belt pulley 12, connect the belt pulley (not shown) of failing standing grain device 4 by belt, for preposition header provides power.

Straw grass binder has piston bundling case, piston 7 is arranged in it, and piston rod 8 is hinged with bent axle 9, when driving gear 11 rotates, driven gear 10 drivening rods, the reciprocating motion of the pistons that are meshed with it, the binder packing, two vertical fixed heads 13 of packing box top welding, built-in beam 18 is established in its upper end, hinge transverse link 15,16, two connecting rods, the one end vertical holding pad 17 that is hinged, the other end of transverse link 15 is hinged with vertical swing connecting bar 14, connecting rod 14 lower ends and piston roof hinge.When reciprocating motion of the pistons, connecting rod 14 swings, and makes holding pad 17 do binder motion up and down through quadric chain, and under the effect of piston and holding pad, the straw grass constantly adds in the bundling case, constantly is compressed and moves backward.A flange 25 is established in the holding pad outside, its effect is to depress bundling dividing plate 19, when moving certain size (fixed arbitrarily) behind the compression bale, need depress a dividing plate, by artificial pressing board, depress dividing plate two sides fluted 20 by holding pad flange 25, be convenient to wear iron wire 21 and tie up, the bale of tying up 23 is pushed outside the outlet gradually.Bundling case back segment both sides do not have boxboard, have only base plate and top board, and two bolts 22 are installed in its rear end, play fixedly boxboard and the effect of adjustable plate spacing.
