Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Like Fig. 1, shown in Figure 2; Comprise drive disk assembly and transplant arm; Drive disk assembly is included in the central shaft 1 of transferring power in the chain-wheel box; Central shaft 1 two ends be fixed with the identical left and right gear housing 3 of interior ', 3, stretch out left and right gear housing 3 ', identical upper left, the upper right transplant arm of structure is housed on 3 outer upper left with the upper right planet axis respectively.The left and right gear housing 3 of central shaft 1 left and right end ', install respectively in 3 the eccentric spur gear 4 in left and right center ', 4; Sky be enclosed within the eccentric spur gear 4 in left and right center on the central shaft ', 4 respectively through left and right flanges 2 ', 2 be fixedly connected with frame; Be installed in left and right jackshaft 6 ', the non-round spur gear 5 in left and right centre on 6 ', 5 respectively with the eccentric spur gear 4 in left and right center separately ', 4 engagements, be installed in left and right planet axis 14 ', the eccentric spur gear 7 of left and right planet on 14 ', 7 respectively with the non-round spur gear 5 in left and right centre separately ', 5 engagements; Left and right planet axis 14 ', 14 stretch out left and right gear housing 3 ', 3 external ends are fixed with the identical left and right transplant arm housing of structure respectively, transplant arm is done periodic oscillations when planet axis is rotated, can winding perpendicular to the axial axis of planet.Described left and right transplant arm housing includes transplant arm base, transplant arm inner housing and transplant arm shell body; With right transplant arm is example: transplant arm base 12 is fixedly connected with transplant arm inner housing 18, and transplant arm base 12 is fixedly connected with planet axis 14, and transplant arm base 12 is placed in cam flange 8; Transplant arm shell body 19 is placed on the transplant arm inner housing 18, and both can relatively rotate; Seedling pin 29 is installed on the transplant arm shell body 19 with transplanting rod 28, with 19 swings of transplant arm shell body; Cylindrical cam 13 with push away seedling cam 11 and together be fixedly connected with gear housing 3 through cam flange 8; Rotate with respect to declutch shift shaft 17 with pushing away the shift fork 16 that seedling cam 11 contacts, declutch shift shaft 17 is fixed on the transplant arm inner housing 18; Slide block 15 is positioned in the slideway of cylindrical cam 13, and fixing through slide block fixed cover 10; Screw 9 one ends are fixed on the transplant arm base 12, and screw 9 other ends are embedded in the translot of slide block fixed cover 10 bottoms, the circumferential rotation of restriction slide block fixed cover 10; Input rocking bar 20, connecting rod 22 and output rocking bar 23 constitute a Space Double endplay device; Input rocking bar 20 1 ends contact with slide block fixed cover 10 lateral projections, and the other end and connecting rod 22 1 ends are hinged, import rocking bar 20 simultaneously and are placed in bolt 21; Bolt 21 is fixed on the transplant arm base 12; Output rocking bar 23 1 ends are connected with connecting rod 22 other ends, and the hole that output rocking bar 23 other ends pass on the transplant arm inner housing 18 is fixed on the transplant arm shell body 19.
As shown in Figure 2, described transplant arm swing is by cylindrical cam---and the Space Double endplay device is realized.Under the effect that cylindrical cam 13 rotates; Slide block 15 slides along the slideway on the cylindrical cam 13; Drive slide block fixed cover 10 along cylindrical cam 13 axial translations, thereby make slide block fixed cover 10 lateral projections and then stir rocking bar 20, and then drive 23 swings of output rocking bar around hold-down screw 9 swings; The periodic oscillations of rocking bar 23 are converted into the periodic oscillations of transplant arm shell body 19, thereby realize the periodic oscillations of seedling pin 29 and transplanting rod 28.Cylindrical cam 13 was in the rise state before pushing away seedling after seedling taking, promptly seedling pin 29 is shown with transplanting rod 28; Before seedling taking, be in the backhaul state after pushing away seedling, i.e. seedling pin 29 and transplanting rod 28 backswing.
As shown in Figure 2, be example with right transplant arm: described transplanting rod 28 adopts three section type to connect, and promptly transplanting rod 28 is connected with spring base 26 through ball pivot chain link 27; Rotate each other between transplanting rod 28, ball pivot chain link 27 and the spring base 26, the rectilinear motion of spring base 26 is converted into the rectilinear motion of angled with it transplanting rod 28.Before from the seedling taking to the rice transplanting, shift fork 16 1 ends contact with pushing away seedling cam 11, and the other end is stirred the compression spring 25 of spring base 26, and transplanting rod 28 is in top, and 24 is the spring back seat; Simultaneously, transplanting rod 28 pivot around ball pivot chain link 27 under the effect of Space Double rocking bar is swung, and is not collinear with spring base 26; When pushing away seedling, shift fork 16 goes to the breach that pushes away seedling cam 11, and under the effect of spring 25, transplanting rod 28 is released rapidly, and ball pivot chain link 27 rotates with respect to spring base 26 and transplanting rod 28, and this moment, cylindrical cam 13 was in the stroke that stops, and transplanting rod 28 is not swung; Pushing away seedling finished to the seedling taking stage; Shift fork 16 breaks away from the breach that pushes away seedling cam 11, and transplanting rod 28 is retracted into top, and this moment, cylindrical cam 13 was in the backhaul state; Transplanting rod 28 is around pivot swing of ball pivot chain link 27, pendulum to ball pivot chain link 27 and spring base 26 in line.
Operation principle of the present invention is:
The transplanting mechanism transmission of power drives left and right tooth wheel housing and rotates, simultaneously to central shaft; In the left and right tooth wheel housing that rotates; The eccentric spur gear in fixing center drives transplant arm through planet axis and rotates through the eccentric spur gear of middle non-round spur gear transmission planet, affects to push away the seedling shift fork around fixedly pushing away the swing of seedling cam; And slide block slides around cylindrical cam, and then realizes the swing of double rocking lever; Finish before seedling taking next time, to push away the seedling shift fork through ascent stage of cam and lift from a rice transplanting; Transplanting rod is increased to peak, and compression pushes away the seedling spring, and slide block is in the backhaul stage of cylindrical cam simultaneously; Transplant arm shows as does the backswing action, and over against the seedling taking of seedling door; To the rice transplanting position, slide block is accomplished the rise stage of cylindrical cam from seedling taking, and transplant arm shows as to do shows action, pushes away the seedling shift fork simultaneously and goes to and push away the seedling cam notch, pushes away seedling spring return and promotes the downward rapid movement of transplanting rod, and rice shoot is pushed in the soil.Thereby order has been accomplished seedling taking, has been shown, the action of rice transplanting, backswing, realizes the capable rice transplanting operation of width.
Above embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
