Description

Transplanting machine Technical Field The present invention relates to a structure for supplying seedlings to a seedling stage of a seedling transplanting device supported at the rear of a machine body in a riding type transplanting machine or an unmanned automatic operation type transplanting machine. Background In a riding type rice transplanter, as disclosed in patent document 1, as for feeding seedlings to a seedling stage of a seedling transplanting device supported at the rear of a machine body, a seedling supporting device capable of supporting seedlings is supported at the machine body so as to be positioned above the machine body, and seedlings can be fed from the rear of the seedling supporting device to the seedling stage. In patent document 1, a seedling transplanting device is supported at the rear part of a link mechanism extending rearward from the rear part of a machine body, and when the seedling transplanting device is lifted by the link mechanism, the upper end part of a seedling stage approaches the rear end part (lower end part) of the seedling supporting device, so that seedlings placed on the seedling supporting device can be supplied to the seedling stage. In a rice transplanter, in order to ensure the transplanting performance of the seedling transplanting device, the seedling transplanting device is often supported at the rear part of a link mechanism in a manner capable of rolling around an axis along the front-rear direction. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2020-5546 Disclosure of Invention Problems to be solved by the invention The present invention is to smoothly supply seedlings placed on a seedling support device to a seedling stage of a seedling planting device supported so as to be capable of rolling in a seedling planting machine provided with the seedling support device. Solution for solving the problem A seedling transplanting machine comprises a machine body capable of running, a link mechanism extending rearward from the rear of the machine body and supported by the machine body in a lifting operation manner, a seedling transplanting device provided with a seedling carrying table supported at the rear of the link mechanism in a manner capable of rolling around an axis in the front-rear direction, a seedling supporting device supported at the machine body in a manner above the machine body and capable of carrying seedlings, a seedling supplying device supported at the machine body in a manner extending rearward obliquely downward from the rear of the seedling supporting device and capable of supplying seedlings carried by the seedling supporting device to the seedling carrying table, and a suppressing mechanism capable of suppressing rolling of the seedling transplanting device, wherein when the seedling transplanting device is lifted to a supply height enabling the upper end of the seedling carrying table to approach the lower end of the seedling supplying device by the link mechanism, the seedling transplanting device is suppressed by the suppressing mechanism, and the seedling transplanting device is capable of supplying seedlings to the seedling carrying table in a rolling state. According to the present invention, when the seedling transplanting device is lifted up to the feeding height by the link mechanism, the upper end portion of the seedling stage approaches the lower end portion of the seedling feeding device, and seedlings can be fed to the seedling stage. In this case, even if the seedling transplanting device is supported by the link mechanism so as to be capable of rolling, when the seedling transplanting device is raised to the feeding height by the link mechanism, the rolling of the seedling transplanting device is suppressed by the suppressing mechanism, and therefore, the seedlings are fed to the seedling stage so as not to scatter from the seedling stage. When the seedling supporting device is supported on the machine body in a manner of being positioned above the machine body, a large height difference is generated between the seedling supporting device and the seedling carrying table. According to the present invention, since the seedling-carrying table is provided with the seedling-carrying device supported by the machine body so as to extend obliquely downward rearward from the rear part of the seedling-carrying device, seedlings in the seedling-carrying part of the seedling-carrying device placed in a high position can be smoothly supplied to the seedling-carrying table in a low position via the seedling-carrying device. As described above, when the seedling-transplanting device is raised to the supply height by the link mechanism, the rolling of the seedling-transplanting device can be suppressed by the suppressing mechanism, and the seedling-supplying device that relays between the seedling-supporting device and the seedling-carrying table is provided, whereby the performance of supplying
