Below in conjunction with accompanying drawing the utility model is described in further detail:

The single file corn combine, it is by frame 16, the right cramp bar 15 that is connected with frame 16, left side cramp bar 18, bottom right linking arm 12 and lower-left linking arm 19 and steel wire rope 36 and assembly pulley 14 are formed, wherein: a, this reaping machine is rear-mounted, by left cramp bar 18 and right cramp bar 15 and lower-left linking arm 19 and bottom right linking arm 12 frame 16 and tractor are connected into unit, main-gear box 24 is housed on frame 16, main-gear box 24 links to each other with jackshaft 27 by lifting belt 26, side in frame 16 is equipped with the roller system of plucking, opposite side is equipped with elevator frid 30 and fruit ear case 21, transition shredding mechanism 32 and cane disintegrating mechanism 37 are housed at the rear portion of frame 16, b, the hinge axes of jackshaft 27 and two linking arms 41 cane disintegrating mechanism 37 and power transmission axis on same axis, c, what airtight two stage speed change was housed in the end of plucking the roller system plucks roller gearbox 29.

As shown in Figure 1, 2.Its course of work is: during results, unit advances along corn ridge culture direction, inside and outside grain lifter 5,1 is guided milpa into the gap of inside and outside snapping bar 7,6 of fore-and-aft tilt configuration from root, and Xuan Zhuan inside and outside snapping bar 7,6 constantly draws cane downwards and send in opposite directions.Because the fruit ear diameter is big, can't pass the gap and come off, pluck the fruit ear that falls because the effect of inside and outside rice-pulling chain 10,3, automatically be slipped on the lifting belt 26, promote through lifting belt 26, fall into fruit ear case 21, after fruit ear is filled, stir fruit ear case control stick 20, Ji Dui or be discharged into transport vehicle and transport outside the field unpacks.Cane after inside and outside snapping bar 7,6 rolls, its top be by transition shredding mechanism 32 chopping, and the bottom of cane and the cane that remains in ground, and are shed on the ground its pulverizing equably by the cane disintegrating mechanism 37 of postposition.So far, this machine has been finished its entire job process.Use the lifting arm 13 of tractor hydraulic hoisting mechanism in operation process, by steel wire rope 36 and assembly pulley 14, cane disintegrating mechanism 37 liftings that control is rearmounted are regulated terrain clearance with endless chain 35, are in the lifting state during operation, prevent to bury.

Its power transmission line is: tractor motive power output shaft 17, drive main-gear box 24 through cardan axis 23, and to elevator drive roll 22, auxiliary by driven roll 33, work by drive lifting belt 26 by the adhesive tape transferring power for its terminal belt wheel 25.Main-gear box 24 right-hand member belt wheels are driven jackshaft 27 and are rotated by Belt Transmission, and jackshaft 27 right-hand member belt wheels 38 are through Belt Transmission, with the cane disintegrating mechanism 37 of power biography to postposition.Axle head sprocket wheel 39 drives sprocket wheel 42 through chain 34, makes one 43 rotation of plucking in the roller gearbox 29, drives two 45 through gear graduation and rotates, and axle head belt wheel 47 makes transition shredding mechanism 32 high speed rotating by Belt Transmission.Two 45 by gear in conjunction with driving three 46, through shaft coupling power is passed interior snapping bar 7 shaft end gears 51 in plucking roller gear case 28, drive outer snapping bar shaft end gear 48 respectively by it, boundary's wheel 52 and boundary's wheel 50 rotate, by gear with transmission of power to interior rice-pulling tooth roller box 11 and outside rice-pulling tooth roller box 31, by inside and outside auxiliary, drive inside and outside rice-pulling chain 10,3 and rotate by the supporting of movable sprocket 9,2.

Shown in Fig. 3,4, the hinge axes of two linking arms 41 of the axis of jackshaft 27 and cane disintegrating mechanism 37 and the design of power transmission axis are on same axis.The jackshaft 27 of this machine is fixed on two bearing blocks on the frame with bolt, and carrying is to cane disintegrating mechanism 37 and the transmission of power of plucking the roller system.Because the 37 ground proximity operations of cane disintegrating mechanism for preventing to bury, are constantly done height control.Guarantee good cane pulverizing quality, this mechanism must possess reliable and stable velocity of rotation., through repeatedly improving design, the same axis and the jackshaft 27 of the pan of two groups of hinge seats 40 is configured on the axis for this reason, then, equipped with hinges pin and adhesive tape.Facts have proved that this design has simple in structure, transmission of power is reliable and stable.

Fig. 5,6 is depicted as and plucks roller gearbox 29, and inside and outside snapping bar 7,6 rotating speeds of maize harvesting machine, inside and outside rice-pulling chain 7,3 rotating speeds are relevant with the pace of tractor, deal with direct production efficiency and the operation quality of influencing improperly.In order to overcome the excessive deficiency of the contiguous gear speed of travel great disparity of tractor design itself, the performance mechanical function is increased work efficiency.Improve to have designed through test in 2 years and pluck roller gearbox 29.Its principle is: with gear change hand lever 44, stir the duplicate gear on one 43, improve two 45 rotating speed, by adhesive tape and gear power is passed to plucking roller gear case 28 and and transition shredding mechanism 32 respectively.At present, in China and the supporting 4YW-1 type of big-powered tractor, the small-sized type of 4YW-2 type and other unit's research does not have the design of gear.

Fig. 7,8 is depicted as and plucks roller gear case 28, and this casing is a maincenter of plucking the main transmission of roller system.By plucking the shaft end gear 51 that roller gearbox 29 passes power inside snapping bar 7, the shaft end gear 48 that drives outer snapping bar 6 rotates, drive simultaneously idle wheel 52 and idle wheel 50 again respectively, power is passed a shaft end gear 53 of inside rice-pulling tooth roller box 11 and a shaft end gear 49 of outer rice-pulling tooth roller box 31, drive its rotation.The design of this casing is that travelling gear is sealed in the casing, makes gear obtain good grease lubrication in casing, reduces dust absorption, prolongs the service life of gear.This part travelling gear of 4YW-1 type of China and 4YW-2 type all exposes outside, without any safeguard procedures.

Fig. 9,10 is depicted as transition shredding mechanism 32, and this device is made up of " Y " shape combination flail knife 54 and cutter shaft 56." Y " shape combination flail knife 54 is riveted spares of knife rest and high strength blade, and with tool rest 55 hinges, the helix configuration is adopted in the arrangement of tool rest.Drive combination flail knife high speed rotating by axle head belt wheel 47 transferring power of plucking 29 2 45 of roller gearboxes, corn top cane chopping after inside and outside snapping bar 7,6 rolled, prevent to stop up, improve the pulverizing quality of cane, through producing the results of examination adaptation high-yield corn and high cane kind.
