Then, the transmission case 30 is set at a predetermined position by the adjusting body 69, so that the ridge coating body 46 is adjusted to a position where the old ridge is repaired and the old ridge is compacted in accordance with the setting position of the rotary 74. Is set.

Further, while the machine frame 1 is towed and advanced along the old ridge by the tractor, the driving means A is operated via the transmission 28 by the output from the PTO shaft of the tractor, so that the driving means A At A, the rotary 74 is driven to rotate in the direction in which the cutting soil is supplied toward the ridge body 46, and the ridge body 46 is driven to rotate in the up-cut direction.

Then, the side and the ridge of the old ridge are sequentially cut as mud for ridge coating over a predetermined thickness by each cutting claw 73 of the rotary 74, and the cut mud is cut into a ridge-coated body. The mud is supplied to the ridge 46 while being compacted along the upper surface and the side surface of the old ridge by the ridge application body 46, and the upper surface and the side surface of the old ridge are formed to a predetermined thickness with the mud. Then, the old ridges are sequentially restored to a predetermined form.

That is, a ridge coater is disposed along a ridge by a tractor, and the tractor is towed along the ridge by the tractor, and power is transmitted by an output from a PTO shaft of the tractor. When the input shaft 3 of the transmission 28 is rotated via the shaft, the first transmission pipe
13 is driven to rotate, and the second output shaft 15 is rotated.
The second output shaft 21 in the transmission pipe 19 is rotationally driven.

When the first output shaft 15 is rotationally driven, the interlocking medium (the sprocket 6) in the transmission case 30 is rotated.
3, 64 and the endless chain 65), the rotating shaft 33 is rotated, and the rotating shaft 33 causes the upper surface coating portion 52 and the side surface coating portion 53 of the ridge coating body 46 to move in the up-cut direction in the traveling direction. It is driven to rotate. In addition, when the second output shaft 21 is rotationally driven, the connection shaft portion of the second output shaft 21 is rotated.
At 70, each cutting claw 73 of the rotary 74 is driven to rotate in the downcut direction toward the advancing direction.

Then, the side and the ridge of the old ridge are sequentially cut to a predetermined thickness (depth) by each cutting claw 73 of the rotary 74, and these cut soils are used as mud for ridge application. The mud is sequentially released and supplied toward the painted body 46, and the mud is applied while being sequentially compacted on the upper surface of the old ridge at the upper surface painted portion 52 of the ridge painted body 46, and the upper surface of the old ridge is restored to a horizontal state. At the same time, the mud is applied while being compacted sequentially on the side surface of the old ridge at the side coating portion 53 of the ridge application body 46, and the side portion of the old ridge is restored to a tapered shape expanding downward. .

At this time, the side coating portion 53 of the ridge coating body 46 is supported on the rotating shaft 33 rotated by the driving means A so as to be able to advance and retreat only in the axial direction, and is always directed toward the side portion of the old ridge. Due to the energization, the side coating portion 53 is applied while the mud is compacted on the side portion of the old ridge with a predetermined pressing force that advances and retreats in accordance with the shape of the side portion of the old ridge, and the side coating portion 53 is formed.
It is prevented that the mud is applied in a state in which 53 strongly bites into the side surface of the old ridge and pressed, and conversely, the mud is prevented from being applied in a state where the side coating portion 53 presses the side surface of the old ridge relatively weakly. As a whole, the old ridges are restored to a state that is hard to collapse.

That is, when the conical side surface coating portion 53 of the ridge coating body 46 receives a pressing force stronger than the urging force of the coil spring 62 due to the mud on the side portion of the old ridge, the side coating portion 53 becomes a sliding cylinder. The body 48 is retreated in the axial direction in the direction away from the stopper 36 along the rotating shaft 33 against the coil spring 62, and the mud is applied to the side surface of the old ridge while being compacted.

When the side painting portion 53 receives a pressing force weaker than the urging force of the coil spring 62 due to the mud on the side surface of the old ridge, the side painting portion 53 is applied to the rotating shaft 33 by the urging force of the coil spring 62. It moves in the axial direction along and applies mud to the side of the old ridge with a predetermined pressing force while compacting the mud. Therefore, the side coating portion 53 is applied while the mud is compacted on the side surface of the old ridge with a predetermined pressing force that advances and retreats in accordance with the shape of the side surface of the old ridge.

Therefore, in the case where the operator of the tractor, which is towing the machine frame 1 along the old ridge, is unfamiliar with the steering wheel and makes a slight error in the handle operation, the side coating portion 53 of the ridge coating body 46 is too close to the side of the old ridge. Even with this, the muddy soil can be applied to the side surface of the old ridge with a predetermined pressing force while being compacted, and the old ridge is repaired as a whole in a state in which it is hard to collapse.

Further, the side surface coating portion 53 of the ridge coating body 46 is urged by the adjusting body 43 by rotating the adjusting body 43 in accordance with the work situation to adjust the advance and retreat along the rotating shaft 33. The biasing force of the coil spring 62 is easily adjusted and set.

Further, the side coating portion 53 of the ridge coating body 46 is driven to rotate in the up-cut direction, so that mud which tends to collapse at the side coating portion 53 toward the bottom of the side portion of the old ridge is formed. It is painted sequentially while being pushed up toward the upper part of the side of the old ridge, and the upper part of the side of the old ridge and the hem of the side of the old ridge are compacted sufficiently firmly with no excess or insufficient soil volume. .

Further, the ridge-coated body 46 is rotationally driven by the driving means A, so that the top-coating portion 52 and the side-coating portion 53 of the ridge-coated body 46 advance while slipping and rotating with respect to the mud. The mud soil is compacted while being applied to the upper surface portion of the old ridge and the side surface portion of the old ridge at the top coating portion 52 and the side coating portion 53 of the ridge coating body 46. The side faces of the old ridges are simultaneously repaired and laid in order, so that the ridges after ridge application are easily crushed and laid without water leakage.

Further, since the ridge-coated body 46 is covered with the cover body 83, the cutting soil that is splashed toward the ridge-coated body 46 by the respective cutting claws 73 is captured by the cover body 83,
While being prevented from being scattered toward the outside of the ridge-coated body 46, the top-coated portion 52 and the side-coated portion of the ridge-coated body 46 are prevented.
At 53, it will be guided as mud for levee application.

Further, the top-coated portion 52 and the side-coated portion 53 of the ridge-coated body 46 are made of a synthetic resin outer cylinder 55 and an outer conical body.
Due to the presence of 59, the mud is prevented from adhering to the top coating portion 52 and the side coating portion 53 during this ridge coating.

Next, in the above-described embodiment, the case where the upper surface coating portion 52 and the side surface coating portion 53 of the ridge coating member 46 are integrally driven to rotate in the up-cut direction has been described. The driving means A and the side coating section 53 may be driven to rotate in the downcut direction.

In addition, the sliding cylindrical body has a spring contact at an abutting portion at an outer end located on the side of the old ridge and abutting against a stopper provided on the rotating shaft, and an inner end located at a side opposite to the abutting portion. The sliding cylinder body is always urged and supported toward the stopper by a spring wound around the rotating shaft, so that the side coating portion having the sliding cylinder body is a side part of the old ridge. When a pressing force stronger than the urging force of the spring is received by the mud, the sliding surface of the sliding cylinder moves backward in the axial direction away from the stopper along the rotating shaft against the spring. Mud soil can be applied to the side of the ridge while being compacted, and it is possible to prevent the old ridge from being restored to a bent state.

According to the third aspect of the present invention, the rotating shaft has the adjustable body for adjusting the urging force of the spring for urging the sliding cylinder body of the side coating portion in the axial direction. The urging force of the spring for urging the sliding cylinder can be easily adjusted and set by performing an adjusting operation as needed.
