DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to bury a ridge plate mechanically and efficiently in order to create a frame of a small plot paddy field for prevention of water leakage, overflow prevention, test research, etc. in a paddy ridge. The present invention relates to a ridge board burying device capable of performing the above.

[0002]

2. Description of the Related Art Conventionally, there has been known a technique of embedding a levee board by hand in order to prevent water leakage and overflow in a paddy field of a farmhouse and to create a frame of a small plot paddy field in a test field. This work was hard work and took a lot of time. With the need for “easy rice production” and improved work efficiency, measures to prevent water leakage and flooding that facilitate water management in paddy rice cultivation are one of the important issues.

[0003] The embedding of the ridge plate has been performed manually, but recently there has been a movement to mechanize this work, and a device for burying the levee plate while excavating around the ridge has been devised and put into practical use. I have.

[0004]

However, in the above-mentioned practically used method, a buried groove is formed in a dry field state and a ridge plate is buried therein. There was a problem that it could not be used. Generally, it is only after water entry (flooding) and scraping that water is found that it is necessary to take measures against water leakage after water entry.

[0005] In order to mechanize the embankment work of ridges to prevent leakage and overflow of paddy fields, it is necessary to reduce the labor, improve efficiency, and stabilize the yield of paddy rice. In the mechanization of the installation work of the frame (leave board) for creating the divided paddy fields, reduction of labor, efficiency, and improvement of accuracy must be achieved. The present invention has been made to solve the above problems and problems.

[0006]

In order to achieve the above object, the present invention provides: At the rear of the tractor, a ridge board burying device is mounted via a three-point link hitch, and the ridge board burying device has a three-point link hitch connecting portion connected to the three-point link hitch of the tractor on the main body frame, A drum-shaped groove with a drilling blade at the lower end, extending in a box shape toward the rear, and a roll-shaped plastic corrugated plate or ridge plate made of a flat plate rotatably mounted around its axis. A ridge board loading section, and a ridge board guiding section for guiding the ridge board fed from the ridge board loading section to the vertical groove formed by the groove section are provided, and the three-point link hitch connection section is provided. It is characterized in that it can be fixed to the left and right with respect to the main frame, and the amount of left and right offset of the ridge plate embedding device with respect to the tractor can be adjusted.

[0007] 2. The above-mentioned ridge board guide section comprises a guide rail and a burying depth adjustment reel for guiding the ridge board fed from the ridge board loading section to the vertical groove formed by the groove section,
By fixing the tip of the ridge plate to the vertical groove as the starting point of embedding, the ridge plate is buried in the vertical groove while moving out the ridge plate along with the movement of the ridge plate embedding device.

[0008] 3. The above-mentioned groove portion comprises a cutting edge protruding forward at the lower end portion, and a box-shaped body having a depth adjustable extending rearward following the cutting edge, and the box-shaped member forms a groove plate with a ridge plate. It is also characterized in that it also serves as a derivative for guiding in the vertical groove formed by (1).

4. A buried depth adjusting reel is installed at the rear end upper portion of the guide rail so as to be vertically adjustable so that the buried depth in the vertical groove of the ridge plate can be adjusted.

[0010]

With the above arrangement, the levee board embedding device of the present invention performs the following operations.

[0011] The ridge board burying device is
It consists of a three-point link hitch connecting part that is connected to the three-point link hitch of the tractor, a cutting groove that has a cutting edge at the lower end and extends in a box shape toward the rear, and a roll-shaped plastic corrugated sheet or flat plate A drum-shaped ridge plate loading portion for loading the ridge plate rotatably about its axis, and a ridge plate fed from the ridge plate loading portion to the longitudinal groove formed by the groove portion. By providing a ridge board guiding part to make it possible to slide and fix the three-point link hitch connecting part to the left and right with respect to the main frame, and to be able to adjust the amount of left and right offset of the ridge board burying device with respect to the tractor, Efficient and accurate burial board embedding work regardless of flooded fields.

[0012] The ridge board guide section consists of a guide rail that guides the ridge board fed from the ridge board loading section to the vertical groove formed by the groove section and a burying depth adjustment reel, with the tip of the ridge board as the embedding start point. By fixing to the flute, the levee board is buried in the flute while moving out the levee board together with the movement of the ridge board embedding device, so at the start of work just fix the tip of the ridge board in the flute, The levee burial work is automatically performed.

[0013] The groove is formed by a digging blade protruding forward at a lower end portion, and a box-shaped body having a depth adjustable extending rearward following the digging blade. By also serving as a guide for guiding the formed flutes, the flutes fed out from the flute board loading unit are guided to the flutes formed by the flutes. In addition, the derivative functions to prevent the inflow of mud in the flooded paddy field, and the levee board can be buried even in the wetland state.

[0014] A buried depth adjustment reel is installed in the upper part of the rear end side of the guide rail so that it can be adjusted up and down, and the burial depth of the levee board can be adjusted to the desired depth ( 15 to 30 cm) to perform burying work, and work accuracy is improved.
