Abstract: This invention relates to a transplanting system of vegetable seedlings with a cultivating tray. It comprises a supply and transportation device, a supply and transportation unit of tray seedlings, a lifting mechanism, and a plurality of auxiliary transport units. The supply and transportation device for a cultivation box includes a dispersal device, a filling unit, a scraping unit, and an excavation unit. The dispersal device is applied for the cultivation box. The transportation unit transports the cultivation box. The filling unit fills the cultivation box with cultivation mediums. The scraping unit scrapes the cultivation medium form the top surface of the cultivation box. The excavation unit digs a hole to the cultivation mediums for the cultivation box. It achieves the function of the supply, transportation, medium filling, scraping, and excavation for the cultivation box. The steering unit for the cultivation box connects with an output-end of the supply and transportation device for the cultivation box, It has a sequentially pull-up positioning stopper. The steering transportation wheel pulled-up followed by the plural stoppers pulled-up and aligned, thus to steer the rotational direction of the transportation wheel and perpendicular to the direction of the transportation cultivation box of the transportation and supply device for the cultivation box. The supply and transportation device for a mother-tray includes a transportation unit for transporting tray, and a supply and transportation unit. The supply and transportation unit of tray seedlings is on the top of the steering unit of the cultivation box to transport the mother-tray with sub-tray and seedlings. Wherein, the transportation direction of the mother tray is the same as the direction of the steering wheel of the cultivation box steering unit. At the top end of the outlet, it builds plural claw mechanisms of the seedling transplant for clawing and put the sub-cell of the mother tray into the cell of the cultivation box. The claw mechanism of seedling transplant is built in a ㄇ-shaped transplant arm. The transplant arm applies two parallel cross-platform guided rods moving forwardly and backwardly. The side of the transplant arm has a expansion push-pull mechanism to push-pull the transplant arm, it clips and releases seedlings to horizontal position. On the top of the transplantation arm, it builds a lifting mechanism to lift the seedling transplantation claw mechanism, so as to clip and put the sub cell to the cultivation box. An inching valve is built beneath the bottom seedling transplant claw mechanism, it is utilized to displace and retain the bottom surface of the mother tray for aligning the seedling transplant claw mechanism. Each cell can be clipped by said seedling transplant claw mechanism continuously. A side of the seedlings transplant claw mechanism is built a tray exit mechanism for discharging the mother tray. The plural auxiliary transport units for the cultivation box connect with the cultivation box steering unit. Under the bottom of the seedling transplant claw mechanism, it builds a retaining stopper to control the cultivation box for making inching displacement and position so that the seedlings can be accurately transplanted into each cell. By means of such installations, it expands the gap of the sub cell of the seedlings one by one and accurately transplant into the cell. After all the seedlings are transplanted into the cell, the auxiliary transport unit moves the cultivation box to the transport unit for the cultivation box. Eventually, it achieves the machinery consistent effects of seedling transplant process saving the manpower, and the man-hour.
