Conjugate cam type high-speed pot seedling transplanting mechanism

Abstract

The invention provides a conjugated cam type high-speed pot seedling transplanting mechanism and belongs to agricultural machinery. A first planetary shaft and a second planetary shaft are symmetrically and rotationally assembled on a planetary gear train mechanism and are spaced by 180 degrees; conjugate cam swinging mechanisms are rotationally assembled on the first planetary shaft and the second planetary shaft respectively through cam boxes and located on inner sides of a planetary carrier casing; transplanting arm assemblies are rotationally assembled on the first planetary shaft and the second planetary shaft respectively through transplanting arm assembly casings and located on outsides of the planetary carrier casing; two ends of a connecting rack are fixedly connected on the first planetary shaft and the second planetary shaft respectively; jaw type sleeves are nested on the first planetary shaft and the second planetary shaft respectively, two ends of each jaw type sleeve are fixedly connected with a corresponding first gear and the corresponding transplanting arm assembly casing, and planetary gears are fixedly connected with the corresponding cam boxes. The conjugate cam swinging mechanisms and the transplanting arm assemblies are arranged on inner side and outer side of the planetary gear train mechanism respectively, and accordingly, the conjugate cam type high-speed pot seedling transplanting mechanism has good dynamics performance, operates stably and is good in transplanting operation effect and high in efficiency.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a high-speed bowl seedling transplanting mechanism. Background technique [0002] Pot seedling transplanting is the orderly transplanting of seedlings with independent nutritional pots. It is suitable for planting various water and dry field crops. It has the advantages of prolonging the growth period, greatly increasing the yield per unit area, and ensuring the maturity of crops. It can also make full use of the land and ensure Germination rate of crops during spring drought and spring flood. In recent years, various forms of pot seedling transplanting mechanisms have emerged at home and abroad, and the transplanting structures adopted 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-...

AI Technical Summary

Problems solved by technology

The main problems of the above-mentioned mechanism are: high requirements on farmland conditions and pot seedling quality, complicated mechanism, high manufacturing cost, large operation vibration, low efficiency and poor operation quality

However, in the practice of production operation, it was found that due to the heavy weight of the conjugate cam swing mechanism, the conjugate cam swing mechanism and the transplanting arm assembly were arranged on the same side of the planetary gear train mechanism at the same time during the structural design. Gravity offset and poor dynamic performance affect the transplanting quality of potted seedlings
