Description

Transplanting machine Technical Field The invention relates to a rice transplanter with a seedling transplanting device, wherein the seedling transplanting device is provided with a seedling carrying table. Background As the rice transplanter described above, for example, a rice transplanter described in patent document 1 is known. A preliminary seedling placement table is provided at the front part of the body of the rice transplanter. The operator can place the prepared seedling pad on the prepared seedling placement table. When performing a seedling transplanting operation using the transplanting machine described in patent document 1, an operator first places a seedling mat on a seedling stage (a "seedling stage" in patent document 1) of a seedling transplanting device (a "seedling transplanting device" in patent document 1). The operator also places the seedling mat supported by the Miao Dianzhi support body on the preliminary seedling placement table. The seedling pad support means an implement for supporting the seedling pad, such as a shovel plate. Then, the operator starts transplanting seedlings by the transplanting machine. With the transplanting of seedlings, seedlings placed on seedling pads of the seedling carrier gradually decrease. When the seedlings placed on the seedling carrier are reduced to a certain degree, the operator interrupts the transplanting of the seedlings and stops the transplanting machine from running. Next, the operator holds the seedling mat placed on the preliminary seedling placement table by hand in a state where the seedling mat is supported by the seedling mat support body. Then, the operator separates the seedling mat from the seedling mat support body and supplies it to the seedling carrying table. In this way, when seedlings placed on the seedling stage are reduced to a certain extent, the operator needs to supply seedling pads to the seedling stage. Moreover, the operation of supplying seedling mats to the seedling stage requires much labor. In order to save labor in the task of supplying seedling mats to the seedling stage, a seedling conveying device is provided that is positioned on the front side of the seedling stage and conveys the seedling mats to the seedling stage. In this case, the seedling-carrying device has a rising portion and a falling portion, and the rising portion is provided in a state of being inclined backward and upward in the front portion of the seedling-carrying device, and the falling portion is provided in a state of being inclined backward and downward in the rear portion from the rear end of the rising portion, so that the entire seedling-carrying device is mountain-shaped. Thus, a space for installing a driving part on which an operator can ride is easily ensured at the lower side of the seedling conveying device. However, in the case where the moving speed of the seedling pad is relatively high when the seedling pad is supplied from the descent portion to the seedling stage, it is expected that the seedling pad is damaged by the impact with the seedling stage or the seedling pad already mounted on the seedling stage. In addition, when the seedling mat is supplied from the descent portion to the seedling stage, the movement speed of the seedling mat is relatively high, and the seedling mat is expected to fly out and not normally placed on the seedling stage.

Solution for solving the problem The seedling transplanting device is characterized by comprising a seedling transplanting device which is positioned at the rear part of a machine body and is provided with a seedling carrying table, and a seedling carrying device which is positioned at the front side of the seedling carrying table and carries a seedling pad to the seedling carrying table, wherein the seedling carrying device is provided with a lifting part and a descending part, the lifting part is positioned at the front part of the seedling carrying device and is arranged in a state of being inclined upwards and backwards, the descending part extends from the rear end of the lifting part to the rear side and is arranged in a state of being inclined downwards and backwards, and the seedling carrying device is configured to supply the seedling pad to the seedling carrying table by sliding the seedling pad carried by the lifting part to the rear side from the descending part, and the descending part is provided with a speed reducing part f
