The position is adjusted, and in this state, the traveling machine 1 is moved forward, and the soil at a high place in the field scene W is scraped by the plow body 24, and the shaved soil is transported by the plow body 24 through the soil introduction port 15a. The traveling guide 1 is guided into the platform 13, the traveling body 1 is moved to a low place in the field, and the operator artificially releases the locking mechanism 19 at that position, tilts the soil carrier 13 backward by its own weight, and The soil in the carriage 13 is discharged to a low place in the field scene W, and by repeating this operation, the field is leveled.

When shaving off a ridge or the like, as shown by the solid line in FIGS. 3 and 4, the closing plate portion 15c is removed from the soil introduction port 15a to open the soil introduction port 15a and open the soil introduction port 15b. A closing plate portion 15d is attached to the moving frame 9, and the plow body 24 is arranged and held in a forward-downward position at one side position in the moving direction of the moving frame 9, and the moving mechanism 9 moves the moving frame 9 to the side of the ridge side with respect to the moving direction. In this state, the plow body 24 can be protruded and arranged at one side position on the ridge side of the traveling body 1, and the traveling body 1 is moved forward in this state, whereby one side of the traveling body 1 is moved. The soil at the side of the ridge can be scraped off by the plow body 24, and the shaved soil can be guided by the plow body 24 into the soil carrier 13 through the soil introduction port 15a. And the existence of crawler tracks It can be scraping the soil ridges Sai etc. was difficult, it is possible to correspondingly increase the flexibility of the field of ground leveling work.

In this case, since the soil drop prevention member 25 is detachably provided on one side plate portion 15 of the soil carrier 13, the plow body 24 is located at one side position in the traveling direction of the moving frame 9. When the soil is introduced into the soil carrier 13 through the soil introduction port 15a by disposing the plow 24 at the side position by the moving mechanism 10 and the soil drop prevention member 25 is moved to the one side plate 15 By being attached to the soil, the soil introduced from the soil introduction port 15a can be prevented from falling out and can be reliably introduced into the soil carrier 13 and, in this case, the other side of the moving frame 9 Since the resistance member 26 which can be penetrated into the field M is disposed in the part, the plow 24 is disposed at one side position in the traveling direction of the moving frame 9 and the plow 24 is moved by the moving mechanism 10 to the side position. And the traveling body 1 moves forward to move along the ridge, etc. Soil can increase the straightness prevent meandering of the traveling machine body 1 by the resistance member 26 at the time of scraping, can be smoothly performed correspondingly operating travel.

In this case, the soil introduction port 15a is located at the center position and one side position of the front plate 15 on the front side in the traveling direction of the soil carrier 13 so as to face the plow body 24 which is selectively arranged.
15b, and closing plate portions 15c and 15d capable of opening and closing the soil inlet portions 15a and 15b are provided. Therefore, when the plow body 24 is disposed at the center position of the moving frame 9, the closing plate portion 1 is provided.
5d, the soil introduction port 15b is opened, and the obstruction plate 15c is attached to the soil introduction port 15a.
When the plow body 5a is closed and the plow body 24 is disposed at one side of the moving frame 9, the closing plate portion 15c is removed to open the soil introduction port portion 15a, and the closing plate portion 15d is connected to the soil introduction port portion 1.
5b can be closed by closing the soil introduction port 15b to prevent the fall of the soil in the soil carrier 13;
In this case, since the moving mechanism 10 includes the moving guide mechanism 11 and the screw mechanism 12, the structure can be simplified, and the manufacturing cost can be reduced.

It should be noted that the present invention is not limited to the above-described embodiment, and for example, the structure of the moving mechanism 10, the soil dropping member 25, the resistance member 26 and the like are appropriately changed and designed.

[0021]

As described above, according to the present invention, it is possible to arrange and hold the plow body at the center position in the traveling direction of the moving frame in a forward and downward manner and adjust the position of the moving frame to the center rear position of the traveling body by the moving mechanism. It is also possible to arrange and hold the plow at one side position in the traveling direction of the moving frame in a forward and downward manner, and to adjust the moving position of the moving frame in the lateral direction on the ridge side with respect to the traveling direction by the moving mechanism. Yes, the plow can be selectively arranged at the center position and one side position of the traveling body, and the moving frame can be moved in the lateral direction,
It is possible to scrape off the soil on the side of the running aircraft, such as on the ridge where it was difficult to cut due to the presence of wheels and crawler tracks of the running aircraft,
Thus, the flexibility of the leveling work in the field can be increased.

According to the second aspect of the present invention, since the soil drop prevention member is detachably provided on one side plate of the soil carrier, the plow can be moved to one side in the traveling direction of the moving frame. When the soil is introduced into the soil carrier through the soil introduction port at one side, the plow is placed at one side and the plow is protruded at the side by the moving mechanism. By being attached to the side plate portion, it is possible to prevent the soil introduced from the soil introduction port from falling out and to reliably introduce the soil into the soil carrier, and in the invention according to claim 3, Since a resistance member that can be inserted into the field is disposed on the other side of the moving frame, the plow is disposed at one side in the traveling direction of the moving frame, and the plow is moved laterally by the moving mechanism. Position to protrude and move the traveling body forward to cut the soil at the ridge Thus, it is possible to prevent the traveling body 1 from meandering and to improve the straightness, so that the driving and traveling can be performed smoothly by that amount. Since the soil introduction port is provided at the center position and one side position of the plate portion facing the plow body selected and arranged, and a blocking plate portion capable of opening and closing each soil introduction port portion is provided, the plow body When locating at the center of the moving frame, remove the blocking plate at the center and open the soil inlet at the center, and attach the blocking plate at one side to the inlet on one side of the soil To close the central soil inlet,
When the plow is placed at one side of the moving frame, the blocking plate at one side is removed to open the soil introduction port at one side, and the blocking plate is inserted at the center at the center. It can be attached to the mouth to close the soil introduction opening at one side position, prevent the soil from falling in the soil carrier, and in the invention according to claim 5, the movement is Since the mechanism includes the movement guide mechanism and the screw mechanism, the structure can be simplified, and the manufacturing cost can be reduced.

As described above, the intended purpose can be sufficiently achieved.
