Abstract

A conjugated cam and planetary gear train combined-type pot-grown rice seedling transplanting mechanism belongs to agricultural machinery and is formed by assembling a uniform / non-uniform speed driving planetary gear train mechanism, a conjugated cam swinging mechanism and a transplanting arm, wherein power drives the uniform / non-uniform speed driving planetary gear train mechanism to rotate through a central shaft, the uniform / non-uniform speed driving planetary gear train mechanism provides power for the conjugated cam swinging mechanism while pulling the transplanting arm to move, and the conjugated cam swinging mechanism enables a housing of the transplanting arm to rotate relative to planetary gears, so that the movement of the transplanting arm becomes the composition of pulling movement and relative rotation of the uniform / non-uniform speed driving planetary gear train mechanism and sharp points of seedling clamping pieces on the transplanting arm form a movement trajectory in a woodpecker manner, to complete the transplantation of pot-grown rice seedlings. The conjugated cam and planetary gear train combined-type pot-grown rice seedling transplanting mechanism has the characteristics of good operation quality, strong adaptability, simple structure, low cost, reliable working, small vibration and high efficiency.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a rice pot seedling transplanting mechanism combined with a conjugate cam and a planetary gear train on a rice transplanter. Background technique [0002] There is no slow seedling stage for transplanting rice pot seedlings, early tillering, and obvious effect of increasing yield. It is the best way to grow rice. In recent years, various forms of transplanting mechanisms have emerged one after another at home and abroad, and the adopted transplanting structures are also different. The main transplanting mechanisms include double-crank transplanting mechanisms, ejector-type transplanting mechanisms, rotary transplanting mechanisms, and pendulum-type transplanting mechanisms. The main problems of the above mechanism are: high requirements on paddy field conditions and pot seedling quality, complex mechanism, high manufacturing cost, large operation vibration, low efficiency and poor ...
