Description

[Detailed Description of the Invention] The present invention involves scraping away the earth and sand from high places near the ridges of rice fields.
The present invention relates to a land leveling device for a tractor that can eliminate the height difference in a rice field by transporting the scraped earth and sand to a low place near the center of the rice field, and will be described in detail with reference to the accompanying drawings as follows.

A loading platform frame 2 for storing earth and sand is attached to the rear of the tractor so as to be movable up and down.

The drawing shows a case in which an L-shaped support frame 3 in which two L-shaped dowels are arranged in parallel at predetermined intervals is installed on a vibrating hydraulic arm 5 at the rear of a tractor using a connecting fitting 4 so as to be able to rise and fall freely. The bottom plate of the loading platform frame 2 is pivotally attached to the tip of the supporting frame 3, and the earth and sand introduced into the loading platform frame 2 are automatically disposed of using the locking tool 6 provided on the top of the support frame 3. The figure shows a case in which the loading platform frame 2 is formed in a dump type manner.

A plow γ is installed diagonally on the side of this loading platform frame 2 with the tip of the plow sticking into the soil.

The drawing shows a mounting frame 10 in which a connecting shaft 9 is protruded from a channel-shaped vertical piece 8, and bolts 12 are attached to a horizontal bar 11 on the bottom plate side of the cargo platform frame 2.
On the other hand, a reinforcing plate 14 with a connecting cylinder 13 is attached to the back side of the plow 7, the connecting shaft 9 is fitted into this connecting cylinder 13 and fixed with Pole N2', and the reinforcing plate 14 is attached to the upper part of the mounting frame 10. The figure shows a case in which the height can be freely adjusted using the adjustment bolt 15 provided, and the plow 7
The figure shows a case in which the upper part of the container is twisted toward the loading platform frame 2 side to facilitate the introduction of earth and sand.

A guide gutter 16 for introducing earth and sand scraped away by the plow 7 into the platform frame 2 is extended and connected above the plow 7.

Since the present invention is configured as described above, the loading platform frame 2 is lowered until the bottom plate becomes horizontal as shown in FIG. When the tractor is moved forward with the plow attached to the ground, the plow tip that is stuck into the soil will scrape away the dirt.

Therefore, by positioning the plow 7 on the ridge side of the rice field and moving the tractor forward, it is possible to scrape off the earth and sand on the ridge side where the earth and sand are gathered higher than the center of the rice field.

After going around the ridge of the paddy field, the position of the plow 7 is gradually moved inward to scrape off the earth and sand from the paddy field.

Since the plow 7 is provided at a height that can be adjusted freely, the length of the plow 7 that is thrust into the soil can be adjusted according to the thickness of the earth and sand in the paddy field to be removed, so that the surface of the paddy field can be made uniform.

This scraped earth and sand is sent into the platform frame 2 through the plow 7.

At this time, since a guide gutter 16 is extended and connected to the top of the plow, the guide gutter 16 guides the soil removed by the plow, so the soil that has been scraped off is introduced into the platform frame 2 very smoothly and is deposited. In addition, the guide gutter 16 also serves to prevent the scraped soil from falling down, so that the scraped soil can be reliably introduced and deposited inside the loading platform frame 2 without falling down.

When a large amount of soil has been loaded onto the platform frame 2, the tractor 1 is moved forward or backward to a low place in the center of the rice field, and the soil loaded on the platform frame 2 is dropped to a low place.
Next, move tractor 1 forward and backward to move plow 7.
The work of burying the fallen earth and sand so that the surface of the paddy field is flat, which used to be done with the help of local human labor, can now be done with mechanical power, greatly improving work efficiency.

In this way, in the present invention, since the plow 7 is provided on one side of the platform frame 2, soil can be introduced into the platform frame 2 and deposited by simply moving the tractor 1 forward with the plow 7 positioned at the base of the ridge. Since the plow 7 scrapes away at a constant thickness, it makes the surface of the paddy field uniform, and when transporting soil, the platform frame 2 can be raised. If so, the tractor 1 can be moved forward or backward with peace of mind without the plow 7 hitting the ground; and even if the loading platform frame 2 is provided at the rear of the tractor 1, there will be no hindrance to the running of the tractor 1. Becomes a ground leveling device for tractors.

Claims (1)

[Scope of Claims] 1. A side-mounted support frame is connected to the rear of the tractor by connecting fittings, and this support frame can be raised and lowered by a hydraulic arm of the tractor, and a loading platform frame is attached to the horizontal tip of the support frame. The rear side of the bottom plate is pivotally attached to the front side of the bottom plate to allow the loading platform frame to freely tilt for soil disposal, and there is a mechanism between the support frame and the loading platform frame that prevents the loading platform frame from tilting and holds the loading platform frame horizontally. A stop is provided on the side of the platform frame, and a plow is installed diagonally so that the tip of the plow is stuck into the soil and the excavated soil is introduced into the shelf as the tractor moves forward. A land leveling device for a tractor, characterized in that a guide gutter is provided in an extended manner to introduce earth and sand scraped away by the tractor into a loading platform frame. 2. The land leveling device for a tractor according to claim 1, wherein the plow tip of the plow can be adjusted in height with respect to the ground.
