Transplanter and floating seedling fetching device and method thereof

Abstract

The invention discloses a transplanter and a floating seedling fetching device and method thereof. The floating seedling fetching device comprises a positioning mechanism, a floating seedling jacking mechanism and a driving mechanism. The positioning mechanism is connected to a rack in a front-and-back moving mode. The floating seedling jacking mechanism comprises a floating frame, ejector pins and a positioning part. The floating frame is connected to the positioning mechanism in an up-and-down floating mode. The ejector pins are connected to the floating frame in a front-and-back moving mode. The positioning part is connected to the floating frame. Before seedling jacking, the driving mechanism drives the positioning mechanism to move forwards, after the positioning part moves forwards along with the positioning mechanism and is positioned through a seedling tray fixing mechanism, the driving mechanism drives the ejector pins to move forwards, and the ejector pins penetrate through corresponding seedling hole water leakage holes of fixed seedling trays on the seedling tray fixing mechanism. The floating seedling fetching device carries out two-direction movement for seedling fetching, positioning is carried out before each time of seedling fetching, it is guaranteed that the centers of the seedling hole water leakage holes in the seedling fetching positions of the fixed seedling trays can precisely coincide with the centers of the ejector pins, operation is reliable, maintenance is convenient, and working efficiency is high.

Description

technical field [0001] The invention belongs to the field of dry land transplanting machines of agricultural machinery, and in particular relates to a floating seedling picking device for precise positioning between a seedling picking mechanism and a seedling hole leakage hole of a seedling tray, and a transplanting machine including the floating seedling picking device. [0002] The invention also relates to a method for taking floating seedlings by using a transplanter with the floating seedling picking device. Background technique [0003] Existing automatic transplanting machine generally adopts the mode that the seedlings are ejected from the seedling hole leaking hole in a whole row. In this method, relying on the electric control method or pneumatic method to control the precise operation of the feeding mechanism, the seedling tray is sent to the predetermined position corresponding to the thimble, and the thimble then moves towards the seedling tray, and ejects the s...
