Circle-ellipse pitch curve gear planetary system transmission case of transplanting mechanism

Abstract

The invention discloses a circle-ellipse pitch curve gear planetary system transmission case of a transplanting mechanism, which comprises a gear sun wheel, a planet carrier, a stander, two intermediate gears, two planting arm gears, two planting arms and two seedlings needles; the transmission ratio design of the transmission gear of the transplanting mechanism is suitable for the seedlings transplanting path of the large seedlings; the pitch curve of the elliptic gear is formed by the means that a section of circular curve is in smooth connection with a section of elliptic curve, the seedlings needles are even in moving speed when the seedlings needles are used for pushing the seedlings due to the circular part of the pitch curve, the seedlings needles are lift up after a seedlings pushing rod is used for pushing the seedlings into the mud, the movement locus of the seedlings needles is changed to be small in a plant pit in the mud, and the seedlings laying and the seedlings floating are hardly generated; and the seedlings movement locus has the minimum attack to the seedlings due to the elliptic part of the pitch curve when the seedlings are withdrawn by the seedlings needles, so that the seedlings are hardly injured.

AI Technical Summary

Benefits of technology

This patented device improves the efficiency of growing crops compared to previous methods that had trouble moving big plants through them due to their tendency towards being pushed too much or getting stuck between obstacles like rocks during growth. By designing the separation-planning mechanisms for larger crop seeds, these devices can help prevent this problem from happening more effectively than older techniques such as hand pickers or darts.

Problems solved by technology

This patented describes an improved structure called a rotor split system used on rice planters. It works well with smaller crops like yellow corn but may be less effective than older types due to its lack of flexibility towards different sizes of crop plants being transported during operation. To address this problem, there have been developed various techniques such as adjustable teeth spacing between two sets of rollers or changing the length of spring elements within each set of roller pairs. These modifications aim to make the moving parts more flexible while still maintaining their strengths over time without causing excessive wear.
