Description

[Detailed Description of the Invention] The present invention relates to an improvement of a multi-row rice transplanter for planting four or more rows.

In the conventional four-row rice transplanter, which has wheels from the front, a seedling planting mechanism, and a seedling stand, the rear end of the transmission case 12 is bifurcated at the rear of the wheels, and both branches are connected to each other. A seedling planting mechanism is attached to each of the left and right sides of the transmission case.

Therefore, in this device, the branch transmission case is necessarily located between the rear axle and the seedling transplanting mechanism, and the wheels and the seedling planting mechanism cannot overlap when viewed from the side of the rice transplanter, so the overall length of the rice transplanter is Moreover, in this type of conventional rice transplanter, the floats located on the outside of both axles are attached to a long arm extending from the forked transmission case so as to be adjustable in vertical movement. Therefore, both bifurcated transmission cases had to be made quite sturdy, which added to the weight of the rice transplanter.

In the present invention, a seedling planting mechanism located inside both axles is attached to a transmission case installed between both wheels, and a support member whose lower end is inclined forward is attached to a horizontal member projecting laterally from the transmission case. By attaching a seedling planting mechanism located outside the wheels, the wheels and seedling planting mechanism overlap when viewed from the side of the rice transplanter, shortening the overall length, and the reinforcing member of the support member is attached to the seedling planting mechanism. The weight of the rice transplanter was reduced by attaching floats located on the outside so that they could be moved up and down.
