The prior art of longitudinal seedling feeding generally realizes feeding and transferring by an intermittent motion mechanism controlling a conveying chain wheel and a conveying chain, for example, an automatic seedling feeding mechanism (CN 201410480383.7) is designed with two parallel conveying chains to be linked, the chain wheel drives the chain to rotate, and a seedling tray is driven to move forwards by a limiting rod. The chain pitch is generally a fixed pitch which is equal to the center distance between adjacent hole bowls of the seedling raising plate.
The prior art has the problems of: because the gag lever post is fixed parallel arrangement mode, can appear the gag lever post location inaccurate because of the interaxial distance sudden change at first seedling tray and the second seedling tray's of growing seedlings department, lead to the second seedling tray arch camber cave dish seedling can't effectively transfer, perhaps the second seedling tray floats and can't realize accurate the transfer seedling at the bottom of the effective screens seedling tray alms bowl on the gag lever post, and automatic transplanting is accurate gets seedling transplanting operation and is difficult to realize. The problem two is present: when the transfer distance of different seedling raising trays changes, the parameters of the seedling conveying device cannot be adjusted in time usually, the whole chain transmission system needs to be replaced, and the adaptability to different specifications of the seedling raising trays is poor.
The research shows that automatic transplant and educate accurate seedling device that send of seedling tray improves the high-efficient practicality of transplanting the mechanism, realizes transplanting operation mechanization, high efficiency, has become a problem that needs the solution urgently in our country agricultural machinery research and development field.
