Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1-Figure 3, it is inner that piston 101 is positioned at discharge chambe 1, and can along the axially reciprocating of discharge chambe 1; Guide rail 102 is positioned at discharge chambe 1 upper surface; Stalk feeding mouth 103 is positioned at the lower surface of discharge chambe 1; Discharge chambe 1 upper and lower surface is run through in rope hose tool hole 104, and the center line in rope hose tool hole 104 overlaps with the center line of guide rail 102.The upper and lower surface of piston 101 is parallel with the upper and lower surface of discharge chambe 1 respectively, and the antetheca that piston 101 contacts with bale has one and slots 105, and fluting 105 runs through its upper and lower surface.The width of fluting 105 is greater than the Breadth Maximum of crochet hook 701, is preferably 1.2 times of the Breadth Maximum of crochet hook 701; The degree of depth of fluting 105 is piston 101 along 1/3 ~ 1/2 of discharge chambe 1 length axially.
Slide crank pin mechanism, comprises crank 5, connecting rod 6 and shank 7, and plane of movement and the bundle encasing bale 4 of this slide crank pin mechanism 3 place planes of restricting are parallel.Crank 5 is rotationally connected with above discharge chambe 1, represents in the drawings with an A, and the other end and connecting rod 6 are rotationally connected; The other end and the shank 7 of connecting rod 6 are rotationally connected; Shank 7 end is fixedly connected with crochet hook 701; Crochet hook 701 place plane and the bundle encasing bale 4 are restricted 3 place plane orthogonal, and have distance e between shank 7 and bundle rope 3 place plane, and often get distance e=1.5d ~ 3d, wherein d is the diameter of shank 7; Shank 7 on guide rail 102 centrally line carry out linear reciprocating motion.Knotter frame (not shown) above discharge chambe 1 be provided with knotter jaw 8, card line wheel 9 and pull rope device 10 being arranged in; Bundle rope 3 surrounds through the guide roller 2 that is fixed on below discharge chambe 1 bale 4, the end that enter discharge chambe 1 and is clamped in the groove of card line wheel 9; Shank 7 meets the one-tenth knot condition of bundle rope 3 on knotter jaw 8 when upper extreme position, meet stay cord condition when lower limit position; The shank 7 driven by crank 5 and piston 101, knotter jaw 8, card line take turns 9, pull device 10 relative motion relation of restricting meets motion sequential condition.
As shown in Figure 2, card line wheel 9 is fixed in knotter frame by its central point C, and card line wheel 9 rotates counterclockwise around C point; Pull rope device 10 to be fixed in knotter frame by its end D, pull rope device 10 around D point reciprocally swinging, clockwise oscillation pulls rope, counter-clockwise swing resets, wherein card line wheel 9 and the axis being parallel pulling device 10 of restricting.Card line wheel 9 moves in the plane parallel with discharge chambe 1 upper surface with hawser device 10.
As shown in Figure 3, shank 7 moves to lower limit position, now ties rope 3 and is positioned at above crochet hook 701, and owing to tying the tension force effect of rope 3, bundle rope 3 falls in the rope hose tool angle that shank 7 and crochet hook 701 formed, and now meets stay cord condition; Be wherein 0.35 ~ 0.5 according to the mechanical design handbook coefficient of friction checked between steel and plastics, can convert the angle of friction between crochet hook 701 and bundle rope 3 is 19.29 ° ~ 26.565 °, thus calculate the rope hose tool angle that formed of shank 7 and crochet hook 701 is 63.435 ° ~ 70.71 °.The rope hose tool angle that shank 7 and crochet hook 701 are formed is less than the friction that can overcome when calculating gained angle and tie rope 3, and therefore, often getting this rope hose tool angle is 50 ° ~ 60 °.
As shown in Figure 4, shank 7 moves to upper extreme position, now tie rope 3 by crochet hook 701 pull-up, be positioned at card line wheel 9 above, meet into knot condition in this position.
As shown in Figure 5, before being accomplished to next bale arrival preset length from a upper bale knotting, slide crank pin mechanism remains static always, now crank 5 conllinear overlapping with connecting rod 6, shank 7 is in upper extreme position, when bale reaches preset length and piston 101 antetheca arrives the rope hose tool hole 104 of discharge chambe 1, driving force is inputted by crank 5.
As shown in Figure 6, shank 7 is driven by crank 5, connecting rod 6 and moves downward in the fluting 105 of piston 101, and in the process, flexible bundle rope 3 will dodge the crochet hook 701 of rigidity, and shank 7 drops to lower limit position, now meets stay cord condition; Wherein for preventing shank 7 and bale 4 from bumping against, shank 7 moves in the fluting 105 of piston 101, therefore when tiing a knot, crochet hook 701 and bundle rope 3 are all in fluting 105.
As shown in Figure 7, shank 7 moves to upper extreme position by lower limit position in the fluting 105 of piston 101, now ties rope 3 tangent with knotter jaw 8, meets knotting condition, so that the bundle rope 3 taken thereon has been wound around knotting by knotter jaw 8; The groove that bundle rope 3 another side and card line are taken turns on 9 is tangent, is clamped by bundle rope 3 so that card line wheel 9 turns over certain angle.
Piston 101 is return, and the antetheca of piston 101 leaves the rope hose tool hole 104 of discharge chambe 1, by stalk feeding mouth 103 straw-feeding, to form next bale.
The operation principle with the tying device mechanism of straight line rope hose tool mechanism is: driving force is inputted by crank 5, through connecting rod 6, shank 7 transmission, realizes the linear reciprocating motion of crochet hook 701.Crank 5 is α with the angle of vertical direction, when α=0, and crank 5 conllinear overlapping with connecting rod 6, shank 7 is in upper extreme position; When α=180 °, crank 5 and the stretching conllinear of connecting rod 6, shank 7 is in lower limit position; When α moves to 180 ° from 0, shank 7 moves downward along the center line of guide rail 102, flexible bundle rope 3 will dodge rigidity crochet hook 701, until shank 7 arrives lower limit position, now tying rope 3 is positioned at above crochet hook 701, owing to tying the tension force effect of rope 3, bundle rope 3 falls in the rope hose tool angle that shank 7 and crochet hook 701 formed; When α moves to 360 ° from 180 °, bundle rope 3 is hooked from bale 4 lower end, bundle rope 3 jointly rises with shank 7 under crochet hook 701 retrains, when uphill process is close to lift end, be positioned at bale 4 top, also will be hooked by crochet hook 701 by the bundle rope 3 that card line wheel 9 blocks one end, until shank 7 moves to upper extreme position, now tie rope 3 tangent with knotter jaw 8, the groove that another side and card line are taken turns on 9 is tangent, meets knotting condition; Pull rope device 10 simultaneously and rotate clockwise 90 ° around fixing point D, bundle rope 3 below knotter jaw 8 has been pulled, bundle rope 3 is made to ride on knotter jaw 8, card line wheel 9 turns over certain angle counterclockwise around fixing point C simultaneously, bundle rope 3 is clamped, knotter jaw 8 to have turned around knotting around the bundle rope 3 taken thereon, pull rope device 10 to reset, with pusher rope mechanism (not shown), the knot accomplished fluently is recessed knotter jaw 8, bundle rope 3 cuts off by cutting knife, complete the knotting of a bale, stalk tying device enters next do action to start, and is formed in order to next bale.
