Description

A kind of corn harvesting bench of self-propelled combine

The annex corn harvesting bench that the present invention relates to self-propelled combine is suitable for a kind of ceding of Taiwan of northern China harvesting approach after reequiping.

Agricultural goes up the self-propelled combine that uses at present, the results wheat is that work quality or dependability are all fine, annual effective storage life is very short, independent corn harvesting bench grain header China does not produce basically, and mostly domestic be to be with a corn header as annex on combine by the producer that produces combine.Because the regional crops of China overwhelming majority were cooked in 1 year two, the Huanghe valley particularly, the wheat and corn producing region, two do two receives, and during harvesting corn, the corn water content is more, causes corn combining threshing broken serious, can't use.

Purpose of the present invention is exactly the annex corn harvesting bench process repacking with self-propelled combine, makes its suitable China agricultural production annual two make two characteristics of receiving, and corn is only received not threshing on this machine of fringe, corn stalk mincing and returning to the field.Make northern China two big chief crop wheats, corn harvest mechanization can close on the grain header in an All-China Federation of Taiwan Compatriots and realize like this.Both increase mechanical effective storage life, reduced agricultural input mechanically again.

The present invention realizes like this, the annex corn harvesting bench of combine is reequiped, dismantle and pluck the fringe plate, every group two snapping bars that rotate in opposite directions, its surface is transformed into helical corrugation or has plucks the spiral that fringe colludes, pluck the fringe ability with increase, and the length of lengthening snapping bar, optimum length is 1000 millimeter.Former both sides are carried the screw feeder of crop to the centre, change whole lateral transfer formula into, with corncob be sent to the ceding of Taiwan about two sides' any one party all can, now deliver to the right side of direction of advance, at the terminal diapire upper shed of carrying screw feeder, elevator in the connection, with the corncob elevator to granary (granary be on the former combine with), corncob is taken squeezing through snapping bar like this, and through carrying screw feeder and elevator, elevator is to granary.Corn stalk is still being stood in the fields, needs straw is smashed, and is sprinkling upon the field and makees fertilizer.On the girder below corn header, the gearbox of mounting strap swivel knife shaft stretches out the swivel knife shaft that has cutter tooth in the two sides of this gearbox.The cutter shaft gearbox is by the main transmission of gimbal coupling and combine threshing part, and the gearbox of increase connects, and this gearbox is that the horizontal rotation with main transmission becomes vertical rotation.Corn harvesting bench is only reequiped these parts, and other parts are constant.Thereby corn harvesting bench is still the separate accessories of a combine, when harvesting corn, takes the wheat ceding of Taiwan, and corn harvesting bench is contained on the combine, only the driving belt of former combine threshing part taken away and need not be got final product.So far reach purpose of the present invention.

Diagram is embodiments of the invention.

The drawing explanation:

1, Zola's beam 2, gearbox 3, driving pulley 4, gimbal coupling 5, engine main pulley 6, cutter shaft gearbox 7, belt pulley 8, screw feeder transmission device 9, screw feeder sprocket wheel 10, snapping bar 11, rice-pulling chain 12, pick out different mouthful 13, right straining beam 14, the passive belt wheel 15 of chopping transmission, chopping drive pulley 16, ear or transport device 17, taiwan cut off and landing oil cylinder 18, cutter shaft 19, ear or transport device driving key wheel 20, carry screw feeder 21, pluck fringe and dial standing grain gearbox 23, granary 24, cutter tooth 25, the elevator travelling gear

The fringe plate of plucking on the annex corn harvesting bench of self-propelled combine is dismantled, two the every group snapping bars (10) of rotation in opposite directions, the surface is transformed into helical corrugation or has and plucks the spiral that fringe colludes and pluck the fringe ability with increase.Length adds grows to 1000 millimeter, breaks corn stalk with minimizing, and its rotating speed is 700～1000 rev/mins.Carrying screw feeder (20) is whole lateral transfer formula, the spiral screw feeder is delivered to the corncob of picking the right side of direction of advance with spiral, carrying the terminal diapire upper shed of screw feeder (20), connect upper scraping plate formula ear or transport device (16), utilize auger elevator and bucket type elevator all can, the present invention selects for use scraper-type to feel best results, with the corncob elevator to granary (23).The power transmission of this repacking is the transmission of former grain header substantially, and by middle belt pulley (7), screw feeder transmission device (8) is passed to and carried screw feeder (20) screw feeder sprocket wheel (9) is that driving force is given snapping bar by engine main pulley (5).Only stretch out a travelling gear (25) at the end of carrying screw feeder (20), pass to sprocket wheel (19), driven ear or transport device (16) work, the elevator speed of elevator (16) approximately should be 1.5 times to 2 times of conveying screw feeder (20) transporting velocity.On the girder below corn harvesting bench, by bolt cutter shaft gearbox (6) is installed, stretches out the swivel knife shaft (18) that has cutter tooth (24) in its two sides, the two end supports of cutter shaft (18) is on the machine frame at two sides of the ceding of Taiwan, in case cantilever.The arrangement of cutter tooth (24) should be cut with leakproof according to the shape difference of cutter tooth, and present embodiment is two L shaped.It links by gimbal coupling (4) and gearbox (2) from cutter shaft gearbox (6) in the rotation of cutter shaft (18), gearbox (2) is connected on the sidewall of self-propelled combine with right post beam (13) by Zuo Zhuliang (1), power by engine main pulley (5) through driving pulley (3)-former threshing cylinder belt pulley, to right flank, chopping drive pulley (15), drive gearbox (2) to shredding transmission negative pulley wheel (14), become horizontal and forward into vertically rotating.Main part of corn harvesting bench such as rice-pulling chain (11) hold up lead device (12) etc. with and the transmission that connects all not have change, former corn harvesting bench comprises the repacking that the front is narrated, being located to disconnect by gimbal coupling (4) to become a complete monomer annex, under the operation of taiwan cut off and landing oil cylinder (17), can rise and reach transportation and descend and to reach duty.Also can wholely take in addition, change the wheat ceding of Taiwan.

Claims (1)

1, a kind of corn harvesting bench that has the self-propelled combine of ear-picking unit and conveying plant, it is characterized in that two the every group snapping bars of rotation in opposite directions, the spiral of fringe ditch is plucked on its surface for helical corrugation or band, conveying plant is whole lateral transfer formula screw feeder, and connect an elevator in the terminal diapire upper shed of this screw feeder, the gearbox of one band swivel knife shaft is installed on the girder below the ceding of Taiwan, is stretched out the swivel knife shaft that has cutter tooth in the both sides of this gearbox.
