However, in the conventional structure described above, soil is introduced into the carrier by scooping it up at the rear edge of the carrier by hand or by moving the tractor backwards, and the rice field soil is not necessarily introduced into the rice field. In addition, in the case of the conventional structure, as shown in Fig. 7, the pivot position c between the mounting frame a and the soil transport platform b, that is, the backward tilting fulcrum position of the soil transport platform b, is not suitable for soil leveling work. In the case of one installed at the front end of soil transport platform b, the tilting angle θ of soil transport platform b tends to be insufficient,
Furthermore, in the case where the pivot position c is provided on both the left and right sides of the soil transport platform b as shown in FIG. This has disadvantages in that the pin d is easily damaged, making it unstable to hold the soil transport platform to the mounting frame, and making it difficult to tilt and rotate the soil transport platform.

As described above, the present invention allows soil in a rice field to be scraped off with a plow by the forward motion of a tractor, and introduces the soil into the soil transport platform through the soil inlet, thereby efficiently transferring a predetermined high level of rice field soil to the transport platform. It can be installed by scraping, and the mounting frame is formed into an L-shape on the sides with left and right vertical bars and left and right horizontal bars, and the left and right vertical bars can hold the front part of the soil transport platform, and the bottom front end of the soil transport platform can be placed and held. Therefore, the mounting frame can hold the soil carrier in a state that hugs it, keeping the soil carrier in a stable state, allowing a large amount of soil to be loaded onto the soil carrier, and allowing the soil carrier to move up and down smoothly. Furthermore, since the rear ends of the left and right horizontal rods of the mounting frame are pivoted to the fulcrum located at the bottom of the soil transport platform between the front end of the bottom and the rear end of the bottom, the tilting angle of the soil transport platform can be adjusted. This allows the soil to be discharged well, and since the fulcrum is located near the center of gravity of the soil transport platform and the soil, the tilting and standing movements of the soil transport platform can be done smoothly and easily. At the same time, the load on the locking mechanism can be suppressed and a more stable holding state can be obtained, so that rice field leveling work can be carried out efficiently.
以上、所期の目的を充分達成することができ
る。 As described above, the intended purpose can be fully achieved.
