Wide and Narrow Row Transplanting Mechanism for Rice Pot Seedlings with Differential Gear System

Abstract

The invention discloses a wide and narrow row transplanting mechanism for rice bowl seedlings of a differential gear system. The existing planetary gear system transplanting mechanism for pot seedlings in wide and narrow rows has the problem that the lateral offset is too large when picking seedlings, which causes the problem of inaccurate seedling picking. The present invention comprises a transmission case, an auxiliary transmission shaft gear, a central shaft, a central shaft gear, a differential train, an upper transplanting arm and a lower transplanting arm; the differential train is a two-degree-of-freedom mechanism, and a fixed transmission ratio is adopted in the transmission case The circular gear or non-circular gear with unequal speed transmission, the gear combination of non-circular gear and interlaced helical gear is used in the gearbox. The transplanting arm of the present invention is also subjected to the driving force of the meshing rotation of the gears in the process of rotating with the gear box to realize the differential rotation. Due to the non-uniform transmission characteristics of the non-circular gears in the differential gear train, the flexible transmission ratio obtained, Combined with the spatial transmission characteristics of the staggered helical gears, while realizing the complex spatial "8-shaped" transplanting trajectory, it is ensured that the seedling picking section of the transplanting trajectory has no lateral offset, that is, "straight seedling clamping" is realized.

Description

technical field

[0001] The invention belongs to the field of agricultural machinery, and relates to a high-speed pot seedling wide and narrow row transplanting machine, in particular to a differential gear system rice pot seedling wide and narrow row transplanting mechanism. Background technique

[0002] At present, there are various types of rice transplanters, but whether it is transplanting in wide and narrow rows or transplanting in equal rows, the seedlings taken by the transplanting mechanism are all blanket-shaped seedlings, which are easy to damage the roots. The seedlings taken by the pot seedling wide and narrow row transplanting mechanism are pot seedlings, and there is no root packing phenomenon between the pots and pots, so there is no problem of root damage during the seedling picking process. Compared with blanket seedlings, transplanting has a shorter This is of great significance for increasing rice yield.
