Each ridge plate 15a is fixed in a state of being inclined with respect to the rotation axis (rotation center of the upper surface restoration body 16), and each ridge plate 15a is
Connecting members 15c, 15 having vertical step portions respectively on the top and bottom
It is fixed by c. The upper side of the side surface restoration body and the upper surface restoration body 16 formed by each ridge plate 15a is covered with a cover.

On the upper side of the earth-filling body 5, a earth-filling amount adjusting device 17 is provided. Further, on the upper side of the leveling drum 15, there is provided a turning handle 18 which is used when the earth-filling body 5 and the leveling body 6 are turned between the working position and the non-working position via the machine frame 4. . Between the hitch frame 11 and the machine frame 4, the ridge coater 1 is rotated around the base end of the machine frame 4 to work the earth fill body 5 and the ridge body 6 through the machine frame 4. When turning to the position and the non-working position, the turning operation causes the earth filling body 5 to move.
Also, a working unit rotating device 19 including a rotating handle 20 capable of adjusting the front-back posture of the ridged body 6 is provided in the front-back diagonal direction in a plan view. The machine frame 4 has a grounding wheel (coulter).
21 is provided via an up-down adjusting device 21a.

When the operator holds the turning handle 18 and turns it in the left-right direction, the earth embankment body 5 and the ridge body 6 are centered on the base end of the machine frame 4 via the machine frame 4. It is rotated to move the earth filling body 5 and the ridge body 6 to either the non-working position or the working position. On the outer peripheral part of the base end of the machine frame 4,
A rotation lock device 4a is provided which locks the earth-filling body 5 and the rectifying body 6 when they are rotated to the working position or the non-working position.

Between the hitch frame 11 and the front end of the machine frame 4, the earth embankment body 5 and the leveling body 6 are rotated around the base end part of the machine frame 4 to adjust the earth embankment body 5 and the space. A gas spring 22 is interposed which acts as an auxiliary when moving the ridge 6 to the working position or the non-working position. The gas spring 22 is used to rotate the earth-filling body 5 and the trimming body 6 from the working position to the non-working position or from the non-working position to the working position via the machine frame 4. When the body 6 is lifted, it can be lifted with a light force, and when the earth-filling body 5 and the ridge body 6 are lowered, they exert an elastic action so as not to drop suddenly due to their own weight. The ridge coater 1 is detachably provided with a stand 23 that is used when attaching / detaching to / from a tractor, or when it is moved or stored.

The trimming drum 15 is the same as that shown in FIGS.
As in the first embodiment of the present invention, adjacent to the mounting base of the rotation center are the base ends of the plurality of ridge plates 15a whose inner end side width is narrow and whose outer end side width is gradually widened in plan view. Adjustable ridge board 15a
Attached so that they have a predetermined overlapping portion 15b with each other,
Although not shown, a folded-back portion may be provided on the overlapping portion 15b to fix the overlapping portion 15b vertically, and a vertical step may be formed and fixed so that the gap of the overlapping portion 15b is narrower on the inner end side and wider on the outer end side. It is a thing.

8 and 9, a second embodiment of the adjusting drum 24 is a circular shape instead of the connecting pieces 15c, 15c of the first adjusting drum 15 shown in FIGS. 4 and 5. The rectifying drum 24 is formed by connecting the rectifying plates 24a by one connecting member 24c. Other configurations are the same as those of the ridge forming drum 15 of the first embodiment.
8 and 9, reference numeral 24b is an overlapping portion.

In the ridge coating machine 1 having such a structure,
Connect the top mast 2 to the top link at the rear of the tractor, and the lower link connecting portion 3 to the lower link, respectively.
Connect by point links so that they can be moved up and down. Tractor PTO
Power is transmitted from the shaft to the input shaft 12 via the universal joint and the transmission shaft. When the ridge coating machine 1 performs the arranging work, the earth embankment body 5 and the ridge forming body 6 are rotated around the base end of the machine frame 4 to move from the non-working position to the working position.
This turning operation is performed by first unlocking the lock device 4a and turning the operator holding the turning handle 18. At this time, the gas spring 22 lightly lifts the earth-filling body 5 and the ridge body 6, and elastically acts so as not to drop suddenly. When the earth-filling body 5 and the trimming body 6 reach the working position, the rotation lock device 4a is automatically locked.

The clutch of the rotary shaft 14 is automatically brought into the connected state in association with the operation of the earth-filling body 5 and the rectifying body 6 rotating to the working state. Then, the power received by the input shaft 12 is transmitted to the rotary shaft 14 through the universal joint, transmitted from the rotary shaft 14 through the machine frame 4 to the transmission cases 8 and 9 and the differential case 10, and the earth filling body 5 and The rectifying bodies 6 are driven respectively. Then, as the tractor 2 travels, the embankment body 5
Further, the trimming work is performed by the trimming body 6. When adjusting the working depth of the embankment body 5 and the ridge body 6, it can be performed by changing the support height of the ridge coating machine 1 by the lower link of the tractor, but basically, the grounding wheel 21 is used. It is performed by adjusting the vertical movement by the vertical adjustment device 21a. Further, the rotating handle 20 is used to rotate the working unit 19
By adjusting the front-rear length of the ridge, the front-rear working posture of the ridge coating machine 1 with respect to the tractor is adjusted.

In the earth embankment 5, a part of the original ridge and the soil in the field are cut by a cutting claw and a sand shaving plate to raise the original ridge side into a ridge shape, and the raised soil is adjusted by the ridge body 6. The ridged surface of the drum 15 (or 24) is eccentrically rotated and hits the ridge slope to form the desired ridge. In addition, the horizontal cylindrical body 16
Thus, the top of the ridge formed by the ridge forming drum is formed flat.

When the ridge coater 1 is connected to the tractor and travels on the road without performing work, the earth embankment body 5 and the ridge body 6 are provided.
Is rotated around the base end portion of the machine frame 4 by the rotating handle 18 to be moved to the non-working position. This rotation operation is performed by first unlocking the lock device 4a and allowing the operator to hold the rotation handle 18 and rotate upward.
At this time, the gas spring 22 has the earth filling body 5 and the ridge body 6
It is lifted with a light force to rotate, and it elastically acts so as not to drop suddenly. When the embankment body 5 and the ridge body 6 reach the non-working position, they are automatically locked by the rotation lock device 4a,
The clutch of the rotary shaft 14 is automatically disengaged.
