Double-track transplanting mechanism based on moving shaft non-circular gear differential gear train

Abstract

The invention discloses a double-track transplanting mechanism based on a moving shaft non-circular gear differential gear train. The double-track transplanting mechanism comprises a gear box, a hole opening arm, a cam, a transplanting arm and an input shaft, under the condition of one power input, the pitch curve of each non-circular gear and the transmission ratio of the two cylindrical gears are designed, so that different preset track movement of the hole digging shovel and the seedling needle is realized; meanwhile, based on the design that the shaft I and the shaft II can float up and down, the hole opening arm and the transplanting arm can reciprocate up and down relative to the gear box, so that the postures of the hole opening arm and the transplanting arm can be better adjusted, and the shape of a hole opening and the transplanting effect are more ideal. Therefore, the double-target automatic transplanting mechanism can meet the requirements of double-target tracks and postures so as to quickly realize efficient and automatic transplanting of the carpet-shaped vegetable seedlings.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a dual-track transplanting mechanism based on a non-circular gear differential gear train of a moving shaft. Background technique [0002] my country is the world's largest vegetable producer and vegetable consumer. With the development of society, people's demand for vegetables is increasing, and the efficient planting of vegetables has significant social value. The vegetable blanket seedling transplanting technology is an efficient and simple transplanting technology, which has gradually become one of the main technical means used in vegetable production. Transplanting vegetable blanket seedlings requires a mechanism to complete complex transplanting actions such as gripping, conveying, hole opening and planting of the blanket seedlings, and requires relatively high requirements for the movement trajectory and posture of the hole opening actuator and the transp...

AI Technical Summary

Problems solved by technology

The transplanting of vegetable blanket seedlings requires the organization to complete complex transplanting actions such as clamping, conveying, opening and planting of blanket seedlings, and has relatively high requirements for the trajectory and posture of the opening actuator and the transplanting arm; The existing transplanting mechanism that integrates hole digging and seedling picking is a combination of a fixed-axis gear train and a cam pair to achieve compound functions. Limited by the structure of the mechanism, although the expected hole opening trajectory can be realized, the attitude is uncontrollable, and there is a hole opening dynamic. The trajectory is still not ideal, resulting in poor planting effect, unreliable operation and other problems
