The transmission frame 2 supports a pretreatment body 6 comprising a rotary tilling device which plows an original ridge and a field on the front side and swells the field into a ridge shape, and is tilled by the pretreatment body 6 on the rear side. A ridge 7 composed of a polygonal conical drum for shaping the soil into ridges is supported. Then, the power received by the input shaft 3 from the tractor is transmitted to the pre-processing body 6 and the ridge body 7 via the transmission frame 2, and each is rotated in a predetermined direction to perform each operation. .

The pretreatment body 6 has an axis of a rotating shaft (not shown) disposed in parallel with the traveling direction of the machine body, and is disposed forward with respect to the axis of the rotating shaft from the transmission end of the transmission frame 2. The axial centers of the protruding front output shafts are connected concentrically. A rear output shaft 9 projects rearward from the transmission end of the transmission frame 2 integrally with the front output shaft.
Power is transmitted to the input shaft 11 of the ridge 7 via the tripod universal joint 10. This tripod universal joint 10
May be another universal joint.

The upper part of the pretreatment body 6 is covered by an upper cover 12, and the upper cover 12 is supported by an upper cover slide device 13 so as to be slidable left and right. The outside of the pretreatment body 6 is covered with a side cover 14. An elastic plate 15 such as a rubber plate is attached to a lower portion of the side cover 14, and has a flexible structure that elastically deforms and returns when it comes into contact with the bank.

The ridge body 7 has a front end portion of a ridge support frame 17 which is rotatable up and down via a fulcrum pin 18 at a rear end of a support frame 16 which projects rearward from a rear side surface of the transmission frame 2. It is supported by. The rotation center of the fulcrum pin 18 is provided substantially equal to the rotation center of the ridge 7. A turning handle 19 is provided between the upper surface of the ridge body support frame 17 and the support portion on the transmission frame 2 side, so that the vertical height of the ridge body 7 can be adjusted.

The transmission case 20 of the ridge structure 7 is supported at the rear end of the ridge structure support frame 17 by a fulcrum pin 21 so as to be rotatable in the horizontal direction. The ridge structure 7 is shown by a solid line in the drawing. It is rotatable to a state shown by a virtual line and a state shown by an imaginary line, and can be fixed at each position in the rotation range by a fixing bolt 22 as fixing means. The rotation range of the ridge 7 is regulated by the rotation range regulating body 22a.

Then, when the ridge body 7 is rotated in the horizontal direction about the fulcrum pin 21 and fixed at a desired position, and the horizontal angle of the ridge body 7 with respect to the body traveling direction is adjusted, The report universal joint 10 bends freely and transmits power to the input shaft 11 of the ridge 7 without any trouble.

In this embodiment, the ridge 7 has a polygonal cone-shaped drum 7 having a dodecagonal ridge line and a flat portion.
And a horizontal cylindrical body 8 protruding in the horizontal direction from the center of the drum, and the polygonal conical drum 7 is eccentrically fixed to the rotating shaft. Then, with the advance of the aircraft, the preprocessing body 6
The soil excavated by the above is applied to the inclined surface of the original ridge by the polygonal cone-shaped drum 7, and the horizontal top of the original ridge is applied by the horizontal tubular body 8 to make the ridge.

The horizontal state is detected and the adjustment is performed.

In the ridge coater 1 having such a configuration,
Since the transmission frame 2 that transmits the power received from the tractor to the input shaft 3 to the pretreatment body 6 and the ridge body 7 has the function of a support frame that supports the pretreatment body 6 and the ridge body 7 and the like. The weight of the entire ridge coater 1 is greatly reduced.
As a result, the load on the tractor is remarkably reduced, and troubles in the hydraulic system, poor weight balance, and the like, which occur in the conventional heavy ridge coater, are eliminated.

In the pretreatment body 6, the original ridge and the field are tilled and raised in a ridge shape, and the cultivated soil is formed into ridges by the regular ridge member 7. Even if the pre-processing body 6 moves up and down during this work, the elastically deformable plate 15 is provided at the lower position of the side cover 14, so that the side cover 14 is being formed while the pre-processing body 6 is working. Even if it falls on the slope opposite to the ridge, the plate 15 elastically deforms and the movement resistance does not increase,
The tractor can go straight. Therefore, a large load is not applied to the mounting base of the side cover 14, and the mounting portion of the side cover 14 is not damaged.

The soil quality of the soil tilled by the pretreatment body 6,
Due to the soil moisture, etc., there is a difference in the tightness of the slope with the ridge 7, and the horizontal angle of the ridge 7 is adjusted with respect to the machine direction according to the soil quality, soil moisture, etc. To do so, the fixing bolt 22 is loosened, the ridge 7 is rotated within the range of the rotation range restricting body 22a, and the fixing bolt 22 is tightened and fixed at a desired position as shown by a virtual line. At this time, the tripod universal joint 10 bends freely and transmits the power to the input shaft 11 of the ridge 7 without any trouble.
