More specifically, 4° In this figure, the mounting frame (3) and the soil transport platform (4) are locked between the mounting frame (3) and the soil transport platform (4), and the above-mentioned installation is performed. A locking mechanism QOJ is provided that maintains the state and automatically releases the lock between the mounting frame (3) and the soil transport platform (4) to enable the soil transport platform (4) to automatically tilt backwards. ing.

(Margins below) The soil transport platform (4) in the drawing has a width approximately equal to the distance between the left and right rear wheels (II) of the tractor (1), and has a superior entrance (1 yen) in the center. The figure shows a case in which a clay platform (4) is formed by the wall αJ, the horizontal bottom wall a, and the side plate αω. In short, it is fine as long as it can transport the soil to be loaded without being crushed.

The connection mechanism (2) in the drawing consists of left and right 1-part link rods (16
)and.

It consists of an upper link rod αE that is pivotally connected to the upper shelf η, a lift arm, and a connecting rod t2 (II), and a shift arm a9.
The mounting frame (31) is provided so as to be moved up and down by the movement of the frame.

The mounting frame (3) in the drawing has left and right vertical bars (6+) and left and right horizontal bars (
7) The left and right spacing is formed to be approximately the same as the width of the superior entrance (121), and it is formed into an L shape when viewed from the side (the same effect can be obtained by curving the corners and making them oval); Attach the tips of the left and right horizontal rods (7) to the shaft 0 by using the crosspieces 0] at the bottom of the soil transport platform (4). l! It is pivoted by l.

The plow (5) in the drawing has side plates (C) on both left and right edges, and is protruded diagonally forward and downward at an appropriate inclination angle on the front side near the bottom of the left and right vertical rods (6) of the mounting frame (3). In other words, there is a mounting plate C2 on the front side near the bottom of the left and right vertical bars (6) of the mounting frame (3).
41 are formed facing each other, and a pivot hole C1'5 is formed on this mounting plate (goods).

By removing it from 21, separation i9' can be eliminated.

Since this embodiment is the same as above, the lift arm (I9) is connected to the horizontal bottom wall (1) of the soil transport platform (4) as shown in FIG.
41 is lowered until it is almost horizontal, and while the lower end of the plow (5) is kept in a state where it is rippled in the soil, the tractor (1) is moved forward. I'm going to go.

This scraped soil is passed through the plow (5) to the upper entrance U.
The soil is fed into the soil transport platform (4) through the rips.

When a large amount of soil is placed on the soil transport platform (4) and loaded in a heap, the lift arm q1 is moved as shown in Figure 3.
The soil transport platform (4) is pulled upwards, and the plow (5) is also pulled up from the soil, and while maintaining this state, the tractor (
1) is driven to a low point in the rice field to transport the loading platform (9), and when the driver releases the locking mechanism (iQ) at the specified position, the soil transport platform (4) will move the loading platform (9). Based on the measurements including the weight, the I2 slam causes the truck to tilt backwards to the fourth factor line, causing a so-called dump operation, and all of the loaded soil falls to a desired low location and is dumped.

After dumping the soil, move forward slightly while lowering the mounting frame (3). The narrowed soil platform (4) will return to its original horizontal state due to the reaction of being dragged, and at this time, the locking mechanism aO) will be activated. Second, the soil transport platform (4) is held in the locked and placed state again, and this process is repeated to level the rice field.
