The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of circle-oval knot curved tooth cylindrical gear planetary system rotary transplanting mechanism is provided.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of circle-oval knot curved tooth cylindrical gear planetary system rotary transplanting mechanism, it comprises gear sun gear, planet carrier, frame, two idler gears, two transplant arm gears, two transplant arms and two seedling pins.The gear sun gear is fixed on the frame, and gear sun gear, two idler gears and two transplant arm gears all are rotatably mounted on the planet carrier, and rotates around center of rotation separately.Two idler gears lay respectively between gear sun gear and two the transplant arm gears, and two transplant arms are separately fixed on two transplant arm gears, and two seedling pins are separately fixed at the front portion of two transplant arms.Described idler gear is fixed in the same rotating shaft by preceding idler gear and back idler gear and forms.Before idler gear all mesh with the gear sun gear, back idler gear all with the transplant arm gears engaged.The pitch curve of preceding idler gear is by smooth the connecting and composing of preceding idler gear circular curve and preceding idler gear elliptic curve two ends, the semi-minor axis of preceding idler gear elliptic curve 10 equates that with the radius of preceding idler gear circular curve the central angle of preceding idler gear circular curve and preceding idler gear elliptic curve is 180 °.The pitch curve of back idler gear is by smooth the connecting and composing of back idler gear circular curve and idler gear elliptic curve two ends, back, the major semiaxis of back idler gear elliptic curve equates that with the radius of back idler gear circular curve the central angle of back idler gear circular curve and back idler gear elliptic curve is 180 °.Angle between the major axis of the major axis of preceding idler gear elliptic curve and back idler gear elliptic curve is 90 °.
The utility model is compared with background technology, and the beneficial effect that has is:
1, the design of the gearratio of transplanting mechanism travelling gear is fit to the rice transplanting track of seedlings;
2, the pitch curve of elliptic gear is by one section circle and one period smooth connection of elliptic curve, the circular portion of pitch curve makes that when the seedling pin pushed away seedling, its movement velocity was even, after transplanting rod pushes rice shoot in the mud, lift on the seedling pin, the planting hole of its movement locus in mud diminish, and be difficult for to produce seedling laying and seedling floating; Track when the oval part of pitch curve makes the seedling taking of seedling pin is difficult for hindering seedling to the strike minimum of rice shoot.
Description of drawings
Fig. 1 is a mechanism principle figure of the present utility model;
Fig. 2 is the pie graph of gear pitch curve of the present utility model;
Among the figure: gear sun gear 1, preceding idler gear 2, back idler gear 3, transplant arm gear 4, planet carrier 5, transplant arm 6, seedling pin 7, frame 8, preceding idler gear circular curve 9, preceding idler gear elliptic curve 10, back idler gear circular curve 11, back idler gear elliptic curve 12.
Embodiment
The utility model comprises sun gear, preceding idler gear and back idler gear, transplant arm planetary gear, planet carrier, transplant arm and seedling pin.The sun gear of drive disk assembly maintains static, and planet carrier rotates around sun gear, transplant arm planetary gear and back idler gear engagement, and preceding idler gear and sun gear engagement, back idler gear and preceding idler gear rotate around same axis.The rotating speed of transplant arm planetary gear is respectively by the rotating speed decision of transplant arm planetary gear with the gearratio and the planet carrier of the gearratio of back idler gear, preceding idler gear and sun gear engagement.
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the utility model circle-oval knot curved tooth cylindrical gear planetary system rotary transplanting mechanism comprises gear sun gear 1, planet carrier 5, frame 8, two idler gears, two transplant arm gears 4, two transplant arms 6 and two seedling pins 7.Idler gear is fixed in the same rotating shaft by preceding idler gear 2 and back idler gear 3 and forms.Gear sun gear 1 is fixed on the frame 8, and gear sun gear 1, two idler gears and two transplant arm gears 4 all are rotatably mounted on the planet carrier 5, and rotates around center of rotation separately.Two idler gears lay respectively between gear sun gear 1 and two the transplant arm gears 4, the preceding idler gear 2 of two idler gears all with 1 engagement of gear sun gear, the back idler gear 3 of two idler gears all meshes with transplant arm gear 4.Two transplant arms 6 are separately fixed on two transplant arm gears 4, and two seedling pins 7 are separately fixed at the front portion of two transplant arms 6.
As shown in Figure 2, idler gear is fixed in the same rotating shaft by preceding idler gear 2 and back idler gear 3 and forms.The pitch curve of preceding idler gear 2 is by smooth the connecting and composing of preceding idler gear circular curve 9 and preceding idler gear elliptic curve 10 two ends, the semi-minor axis of preceding idler gear elliptic curve 10 equates that with the radius of preceding idler gear circular curve 9 central angle of preceding idler gear circular curve 9 and preceding idler gear elliptic curve 10 is 180 °.Similarly, the pitch curve of back idler gear 3 is by smooth the connecting and composing of back idler gear circular curve 11 and idler gear elliptic curve 12 two ends, back, the major semiaxis of back idler gear elliptic curve 11 equates that with the radius of back idler gear circular curve 9 central angle of back idler gear circular curve 11 and back idler gear elliptic curve 12 is 180 °.Angle between the major axis of the major axis of preceding idler gear elliptic curve 10 and back idler gear elliptic curve 12 is 90 °.
