The pivot member 4 can be fixed at an arbitrary pivot position by inserting and removing the positioning pin 10 and the selection hole 9. Reference numeral 11 denotes a circulating band. In this case, an endless chain is used. A supporting shaft 12 is attached to the tip of the revolving member 4, and a circulating band 11 is provided between the supporting shaft 12 and the rotating shaft 7. , And circulates through the drive mechanism 13 using the power of the traveling body 1 as a drive source. In this case, the driving mechanism 13
The main shaft 14 is supported in the traveling direction, the power take-out shaft 15 provided on the traveling body 1 is connected to the main shaft 14 by a universal joint 16, and a chain mechanism 17 is arranged between the main shaft 14 and the rotary shaft 7. And the rotation of the power take-off shaft 15
The circulating belt 11 is configured to be circulated and run via the. Numeral 18 denotes a soil member, which is formed in a side U-shaped plate and includes a blade portion 18a, a middle plate portion 18b and a base portion 18c.
Is mounted at an interval on the outer surface thereof with bolts 19. Numeral 20 denotes a stabilizing member, which is formed in a sled plate shape. A bracket 21 is attached to the side surface of the revolving member 4 so as to be movable in the right and left directions.
2 is attached so as to be vertically adjustable, and a stabilizing member 20 is attached to the support rod 22. Note that the stabilizing member 20 is not limited to the sled shape, and may be a wheel shape. In this embodiment, since the turning member 4 is vertically turned, the relative position of the soil member 18 with respect to the soil W can be changed and fixed by the fixing mechanism 5 to move the turning member 4 vertically. The machine frame 3 is advanced, and the circulating belt 11 circulates and travels in a direction intersecting with the traveling direction by the drive mechanism 13, and the earth work can be performed by the soil member 18 by the circulating travel. At this time, the stabilizing member 20 comes into contact with the soil to perform functions such as stabilizing the working depth and progress of the soil member 18. As a preparatory work for ridge creation or restoration work by a ridge creation machine, in the case of cutting or weeding the soil W on the upper surface of the ridge, as shown in FIG.
8, the lower circulating running area is vertically turned so as to be substantially parallel to the upper surface of the ridge, and in this state, the turning member 4 is fixed in position by the fixing mechanism 5 and the traveling body 1 is driven in the direction of forming the ridge.
The driving mechanism 13 causes the circulating belt body 11 to circulate in a direction intersecting with the traveling direction, and the plurality of soil members 18 can cut and wipe the soil W on the upper surface of the ridge by the circulating traveling. it can. The soil W that has collapsed and accumulated at the foot of the ridge
In the case of cutting, digging and weeding work, as shown in FIG. 7, the turning member 4 is turned vertically so that the tip side circulation running area of the soil member 18 is immersed in the skirt of the ridge, and fixed in this state. When the turning member 4 is fixed in position by the mechanism 5 and the traveling body 1 travels in the ridge formation direction, the driving mechanism 13 drives the circulating belt 11.
Circulates in a direction intersecting the traveling direction, and by this circulating traveling, the plurality of soil members 18 scrape the soil W at the skirt of the ridge and discharge it to the field side, and thus collapse into the skirt of the ridge. The soil W accumulated on the ground can be shaved and weeded. In the case of cutting and weeding the soil W on the side surface of the ridge, as shown in FIG. 8, the turning member 4 is moved so that the lower circulation running area of the soil member 18 is parallel to the side surface of the ridge. In this state, the turning member 4 is fixed in position by the fixing mechanism 5 and the traveling body 1 travels in the direction of ridge formation, and the driving mechanism 13 causes the circulating belt 11 to cross in the direction intersecting the traveling direction. It circulates, and the plurality of soil members 18 scrape off the soil W on the side surface of the ridge and discharge it to the field side by this circulation traveling,
Therefore, the soil W on the side surface of the ridge can be cut and weeded. In addition, unevenness leveling work in a field scene, weeding work,
Crushing and spreading compost, rice husk, and soil scattered in the field scene,
In the case of a hard residual snow treatment operation, a cleaning operation, a backfilling operation of a tilling rotary mark, or the like, as shown in FIG. 9, the revolving member 4 and the lower circulation traveling region of the soil member 18 are parallel to the upper surface of the field. As described above, when the turning member 4 is fixed in position by the fixing mechanism 5 and the traveling body 1 is run in this state, the circulating belt 11 circulates in a direction intersecting the traveling direction by the driving mechanism 13, By this circulation traveling, the plurality of soil members 18 scrape the soil W on the upper surface of the field, the upper surface of the agricultural road, and the like, and can perform the above-described various types of soil operations. It should be noted that the present invention is not limited to the above embodiment, and the structure of the revolving member 4, the structure of the fixing mechanism 5, the structure of the circulating band 11, and the structure of the drive mechanism 13 are appropriately designed and changed.
