Description

The multi-functional grain header of stacking formula

Technical field

The utility model relates to agricultural harvesting machinery, and particularly a kind of being used for is partitioned into the multi-functional grain header that stacking is put after harvesting corn, reed, wheat also can gather in.

Background technology

What existing harvesting technology was commonplace is combine, and high efficiency is suitable for the large tracts of land operation, and wants grading operation, but complicated in mechanical structure, huge costs an arm and a leg, and is not suitable for self-employed farmer's small-scale operation.With the field be national poverty-stricken area, per capita area of cultivated farmland is less than one mu, annual income is lower, the expensive plant equipment of cannot afford, and also ground is uneven, much parts are sand soil, always always be by pure manual harvesting for this reason, time-consuming, the effort of this manual type, a strong labour can only gather in one mu of corn or reed in one day at the most, not only labour intensity is big, and operating efficiency is very low.This backwardness for a change, the design people is by practical studies repeatedly, proposed a kind ofly can replace the manpower work, is fit to operation on a small scale, and low price improves the multi-functional grain header of harvesting and effect in heaps.

Summary of the invention

At pure manual operations in the past, inefficiency, time-consuming, effort, the purpose of this utility model be to provide installations, maintenance, it is all very convenient to operate, and mechanical adaptability is strong, no matter be that the field harvesting can be directly advanced in smooth field, the field that little ditch is arranged, clay field, sandy soil field, the plant of general lodging also can normally be gathered in, and need not shift to an earlier date manually and clear the way, and harvested straw is vertically stacked, manual banding very easily, with the multi-functional grain header of walking tractor matching.The purpose of this utility model is to realize by following technical scheme:

A kind of multi-functional grain header of stacking formula of and walking tractor matching comprises engine, transmission mechanism, header, lift, stacking mechanism.Said engine is the diesel engine of hand tractor, simultaneously the power source of header;

Said transmission mechanism is made up of engine belt pulley, big belt pulley, two spur bevel gears, drive sprocket and driven sprockets, engine belt pulley is connected with big belt pulley by V belt, big belt pulley and spur bevel gear by key and bolt on one, on another axle, drive sprocket is connected with driven sprocket by chain and power is passed to header by key and bolt for another spur bevel gear and drive sprocket;

Be hung on the hand tractor before the said header, (upper and lower) two conveyer belts that have the pulling tooth, three wheel cutters, backplates be installed and organize rice crop-supporting plate and rice pulling wheel is formed more by parallel.Three wheel cutters are individually fixed on three axles, three axles are connected with living in the header frame by bearing, be fixed in another belt wheel and nethermost wheel cutter below belt wheel, driven sprocket, drive sprocket, the drive sprocket on first and the 3rd successively, be fixed in a drive sprocket and a wheel cutter successively on middle second.Driven sprocket on transmission mechanism drives first by drive sprocket, make first rotation, go up drive sprocket for first and drive second rotation, drive the 3rd rotation, two conveyer belt run-in synchronisms that this makes three wheel cutters and has the pulling tooth by the sprocket wheel on second simultaneously.In order to stop that the crops tangerine bar that cuts off enters between sprocket wheel and chain between three, have between upper and lower two conveyer belts of pulling tooth and on the header frame, fixing the iron sheet backplate.Fall down when avoiding crops tangerine bar to cut off, and cut off back tangerine bar and put the shop,, fixing many group rice crop-supporting plates and rice pulling wheels on the underbeam of header frame in backplate the place ahead along sending the right;

Said lift is made up of connecting rod, pull bar, lever, worm gearing, landing dish and landing scale (demonstration) table, the header frame serves as that the swing fulcrum is connected with the complete machine frame is alive by connecting rod with active spur bevel gear shaft centre line, connecting rod, pull bar are lived mutually by pin with lever and are connected, balance pivot is coaxial with worm gear, the upper end of worm screw is the landing dish, and the steel wire of landing graduation apparatus directly is around on pot wheel shaft.Rotate the landing dish and make lever swing by worm gearing, lever rises header by the pull bar swing connecting bar or descends, and the rotation of worm-wheel shaft simultaneously realizes the swing of landing graduation apparatus pointer, and graduation apparatus shows the landing tolerance of header.

Said stacking mechanism is by being installed on drive sprocket on the hand tractor live axle, being installed on the driven sprocket on the variable-speed shaft and initiatively straight spur gear, the driven straight spur gear, connecting rod, the rake that are installed on the camshaft are formed.Drive sprocket is connected with driven sprocket by chain, and initiatively straight spur gear is meshed with driven straight spur gear, and driven straight spur gear and cam are fixed on one, passive blade of connecting rod one end welding, and the other end is installed rake.During the hand tractor walking, drive sprocket on the live axle drives driven sprocket and initiatively straight spur gear rotation by chain, initiatively straight spur gear drives big straight spur gear and cam rotation, cam whenever circles and drives 60 ° of passive blade commentaries on classics, rake is turned over straw in heaps is placed, general hand tractor walking 3m, cam circles, and rake is turned over once.

During work, grain header is preposition to hang on the supporting tractor, tractor dynamic power rotates synchronously by three axles that transmission mechanism drives header, to be put the shop by rice pulling wheel and the right-hand member that (upper and lower) two conveyer belts that have the pulling tooth are delivered to the ceding of Taiwan by the straw that wheel cutter cuts off, rake also begins to heap straw simultaneously, and the every walking of hand tractor 3m, rake finish once the work of knocking off in heaps, dry straw as needs, rake can be installed straw is directly put the shop.According to crops harvesting and surface state,, can adjust the position on cutter and ground at any time by the landing dish on the lift no matter hand tractor is walking or halted state.Advantage of the present utility model is:

The utility model adopts the mechanized harvest straw, greatly reduces labour intensity, has improved operating efficiency, and is time saving and energy saving; The utility model can be fit to supporting employing hand tractor power, and its drive path structure distribution is reasonable, and efficient height, energy consumption are little; The utility model has been realized the harvesting of stacking formula, and changing the bar shaped lay is that compartment is stacked, and has saved and has tied up transportation manpower work workload before; The utility model is except the wheat crops harvesting that suitable common flat work is planted, and gather in the band field of the banded plantation at interval of the two kinds of crops that also can suit, and more specifically meaning also is to be suitable for the alkaline reed of rough sand ground.The utility model straw as required can be stacked, and also can launch lay.
