Abstract

The invention relates to an automatic seedling fetching device for a transplanter. The automatic seedling fetching device comprises cam mechanisms, an ejector pin supporting piece meshed with the cam mechanisms and a plurality of umbrella-shaped ejector pin seedling fetching mechanisms mounted on the ejector pin supporting piece, wherein the umbrella-shaped ejector pin seedling fetching mechanisms are driven by the cam mechanisms for a reciprocating rectilinear movement, so that lining mechanisms on the umbrella-shaped ejector pin seedling fetching mechanisms can be closed and opened; ejector pins move forwards, and in addition, the linking mechanisms on the ejector pins can be opened to form umbrella-shaped planar structures. According to the invention, the linking mechanism at the top end are covered by umbrella-shaped flexible materials, so that the stressed area can be effectively increased, and seedlings in a seedling disc can be effectively taken out of the seedling disc; the automatic seedling fetching device is simple in structure, easy to process and high in working performance, and the seedlings can be fetched automatically and orderly.

Description

technical field [0001] The invention relates to the field of transplanting machine parts in agricultural machinery, in particular to an automatic seedling picking device for a transplanting machine. Background technique [0002] In our country, the planting methods of crops are generally divided into two types: direct seeding and seedling transplanting. Although the man-hours and manpower invested in seedling cultivation and transplanting are much greater than those of direct seeding, compared with the direct seeding cultivation method, seedling cultivation and transplanting is through intensive seedling cultivation of crop seeds during the sowing season. Transplanted to the field for growth, therefore, through the planting method of centralized seedling cultivation and transplanting, the planting season of the crops can be advanced, the contradiction between the stubble in the crop planting season can be alleviated, and the crop planting season can be extended, which is con...
