Description

[Detailed description of the invention] This invention is a tractor soil that is extremely convenient for the work of scraping off soil from high places along the ridges of rice fields and transporting this scraped soil to low places in the center to correct height differences in rice fields. The configuration of the transport device will be described in detail with reference to the accompanying drawings as follows.

An upright front wall 2 and a horizontal bottom wall 3, each having a width approximately equal to the distance between the left and right rear wheels 1 of the tractor a, form an earth transport platform b.

Reference numeral 4 in the figure is a side plate.

A soil inlet 5 is formed in the middle of the rising front wall 2 of the soil transport platform b.

The spacing between the left and right vertical bars 6, 7 of the mounting frame c to which this soil transporting platform b is attached is formed to be approximately the same as the width of the soil introduction port 5, and the soil transporting platform b is attached to the lower end of this mounting frame c. is pivoted to the mounting frame c so as to perform a dump operation. The one shown in the drawing is pivoted at the front corner of the soil transport platform b.

A mounting plate 9 is attached to the lower front side of the left and right vertical bars 6, 7 of the mounting frame c in a facing state, and pivot holes 10 are bored in this mounting plate 9 in multiple stages at intervals.

Soil introducing plate 17 with a triangular plow 8 connected to the lower end
side plates 17' to prevent soil from spilling on both sides of the
will be established.

Mounting shafts 11 are provided horizontally protruding on the left and right sides of the soil introduction plate 17, and the mounting shafts 11 are fitted into the selected pivot holes 10 so that the upper edge of the soil introduction plate 17 faces the lower part of the soil introduction port 5. hang it on the mounting frame c. An inclined retaining plate 18 which also serves as a reinforcing plate is attached to the back side of the plow 8 and the soil introduction plate 17, and this inclined retaining plate 18 is brought into contact with a slat plate 19 passed to the lower part of the mounting frame c.
7 to give an appropriate inclination.

The upper part of the mounting frame c and the rising front wall 2 of the soil transport platform b
A releasable locking device 12 is provided at the top of the holder 12 to lock the two together in a superposed state. The locking device 12 in the drawings is
The figure shows a case in which the hook piece 12', which is pulled down by a spring 20 provided at the upper part of the mounting frame c, is formed so as to be resiliently engaged with a roller 12'' provided on the reinforcing bar upper part 2' of the front wall 2. A mounting frame c to which such a soil transport platform b is attached is installed at the rear of the tractor a via a coupling mechanism d so that it can be raised and lowered freely using the lift arm 13.The coupling mechanism d in the drawing has one end facing the tractor a side. A lower link rod 14 is pivotally connected, and the other end is pivotally connected to the soil transport platform b side, and an upper link rod is pivotally connected at one end to the tractor a side and the other end is pivotally connected to the soil transport platform b side. 15, and a connecting rod 16 that connects the lift arm 13 and the lower link rod 14.

Since the present invention is constructed as described above, as shown in FIG.
When the upper tractor a is lowered until it becomes approximately horizontal and the upper tractor a is moved forward along the ridge while maintaining this state, the plow 8 scrapes away the soil at the high points of the ridge of the rice field.

This scraped soil is from plow 8 to soil introduction plate 17
The soil is then fed into the soil transport platform b through the soil introduction port 5.

When a large amount of soil has been piled up on the horizontal bottom wall 3, the lift arm 13 lifts the soil transport platform b upwards as shown in Fig. 2, and while maintaining this state, the tractor When the driver releases the locking device 12 after moving forward or backward to a certain point, the soil transport platform b swings greatly due to its own weight including the soil, causing all the loaded soil to fall.

Repeat this process to level the rice field. After the soil has fallen, the locking device 12 can be easily returned to the locked state by moving forward a little while returning the soil transport platform b downward.

To remove soil in the present invention, mounting plates 9 are attached to the lower front side of the mounting frame c in a facing state, and a long soil introduction plate 17 with a gap 8 connected to the lower end is suspended between the left and right mounting plates 9. The plow 8 reliably scrapes off the soil, and the scraped soil is carried upward by the continuous soil introduction plate 17 and introduced into the soil transport platform b through the soil introduction port 5.

In addition, if this structure is adopted, the plow tip can be lifted up when it is not desired to remove soil, which is convenient.In addition, by selecting the pivot hole 10 of the desired height, the height of the lower end of the plow 8 can be adjusted. It can also be easily adjusted up and down, and for example, when used as a mere transport vehicle without excavating soil, it is also possible to lift it upward to a position where the plow 8 does not touch the ground.

Furthermore, by making the plow 8 and the soil introducing plate 17 separately, only the plow 8 can be sufficiently hardened to make it durable for use, and the soil introducing plate 17 has a side plate 17' formed by pressing or the like to prevent soil from spilling. Since this is provided, the scraped soil can be reliably introduced into the soil transport platform b.

In this case, the same effect can be achieved even if the side plate 17' has a curved edge.

An inclined retaining plate 18, which also serves as a reinforcing plate, is attached to the back of the plow 8 and the soil introduction plate 17, so that the connection between the two is strong. By selecting the shape of the inclined retaining plate 18, it is possible to give the soil introduction plate 17 and the plow 8 an appropriate inclination angle. You will be killed.

In this way, the present invention allows the plow 8 to scrape off the soil at a certain depth by simply moving the tractor a forward, and the soil can be loaded into the soil transport platform b and dropped at a desired location, making the surface of the rice field extremely rough. It can be easily flattened, and when used as a rice field, the depth of the water can be made uniform, which improves rice cultivation management.
This is a soil transport device for tractors that exhibits excellent practicality and can improve harvests.
