Problems solved by technology
However, the transmission characteristics of the non-circular gear train of the currently designed rotary insertion mechanism are not very good, the vibration of the machine is relatively large, and the adaptability to the size of the transplanted seedlings is poor
For example: the trajectory and posture of the existing non-circular gear splitting mechanism composed of an elliptic pitch curve can cause serious damage to the seedlings when picking seedlings, and the hole for transplanting produced after pushing the seedlings and transplanting is also relatively large. , it is easy to cause inverted seedlings and floating seedlings

Embodiment Construction
[0009] The patent of the present invention will be further described below in conjunction with the drawings.
[0010] Such as figure 1 As shown, an ellipse-elliptic pitch gear planetary system rotating box of a separating and planting mechanism mainly includes a sun wheel 1, two intermediate wheels 2, two planet wheels 3, a planet carrier 4, two planting arms 5, and two A seedling needle 6, a frame 7; the sun gear 1 is fixedly connected to the frame 7, and the planet frame 4 is installed on the frame 7; the two sides of the sun gear 1 are symmetrical, and the middle wheel 2 and the planet wheel 3 are arranged in sequence; and The rotation centers of the two intermediate wheels 2 and the two planet wheels 3 are fixed on the planet carrier 4, the two planting arms 5 are fixedly connected to the two planet wheels 3, and the two seedling needles 6 are fixedly connected to the two planting arms 5 respectively. The middle wheel 2 is conjugated with the sun gear 1 and the planet gear 3 ...

The invention discloses an elliptical-elliptical knot curve gear planetary system rotary tank for a transplanting mechanism. The elliptical-elliptical knot curve gear planetary system rotary tank mainly comprises a sun wheel, two middle wheels, two planet wheels, a planet carrier, two transplanting arms, two seedling needles and a rack; the transmission of a transmission gear of the transplanting mechanism is less in seedling damage than rice transplanting; the knot curve of the sun wheel is composed of two elliptical arc curves with the same long shafts and different short shafts, two curves are in smooth connection and respectively occupy a 180 DEG central angle, the seedling needles cannot damage the seedling when the seeding is taken out by adjusting the short shafts of the two sections of elliptical arcs, the hole is small while the seedling is pushed, and the seedling floating and seedling laying seldomly occur.
Description
Technical field [0001] The invention relates to a high-speed rice transplanter, in particular to an ellipse-ellipse-pitch curve gear planetary system rotating box of a separating and planting mechanism. Background technique [0002] The rotary transplanting mechanism of the high-speed rice transplanter has the advantages of fast transplanting speed, high production efficiency, and good working performance. However, the non-circular gear train transmission characteristics of the currently designed rotary separating-planting mechanism are not very good, the vibration of the machine is large, and the adaptability to the size of planting seedlings is poor. For example, the existing non-circular gear separating and planting mechanism composed of a kind of elliptic pitch curve has serious damage to the seedlings when picking the seedlings, and the planting holes produced after pushing the seedlings are also large. , Easy to cause the phenomenon of falling and floating seedlings. Ther...
