The base edge of the body E is fixed, and the pressing plate body E is made of a flexible metal such as nylon resin, vinyl chloride resin, or spring steel used for a leaf spring. It becomes almost flat and can be bent in an arc shape by an external load. A self-elastic material that is deformed and restored to a substantially flat shape is used. However, the rotary adjuster 5 is forcibly rotated around the rotation axis P in the direction of the arrow in the figure, and the rotary adjuster 5 is in sliding contact with the heel W. the upper surface W ₁ of one side W ₂ and ridge W of ridge W are configured to tighten voltage rectifier ridge by.

Since the first embodiment of the present embodiment has the above-described configuration, as shown in FIG. 2, the rotary trimming body 5 of the trimming mechanism 4 is disposed at the rear side position of the traveling machine body 1, and the trimming mechanism 4 is disposed on the traveling machine body 1. driven by the power take-off shaft 1b, for example, as shown in FIG. 16, in the field M, the vehicle body 1 forward straight running direction of the arrow, during the forward running straight, the upper surface W ₁ and the upper side surface of the old ridge W Is ground by the pretreatment rotor 15a of the pretreatment mechanism 15, the field M mud at the time of dredging W is embanked on the old dredge W by the embankment rotor 14a of the embankment mechanism 14, and the rotational rotation of the rotary trimming body 5 with respect to the dredging W contacting the upper surface W ₁ of one side W ₂ and ridge W of ridge W and clamping voltage rectifier ridge makes it possible to perform Seiaze work continuously, and, the traveling machine body 1 approaches the front of the front ridge W This makes it impossible for the vehicle to travel straight forward. So that the cause is not yet Seiaze portion T of more ridge W.

  In this forward limit position, the travel of the traveling machine body 1 is stopped, and the rectifying mechanism 4 is disposed in a side position of the traveling machine body 1 so as to be reciprocally movable in the direction of the grading work by the guide mechanism 6. As shown in FIGS. 11, 12, and 13, when the adjusting mechanism 4 is driven, the reciprocating mechanism 7 moves the adjusting mechanism 4 forward to perform the adjusting operation of the unaligned portion T of the kite W. 11. After the grading mechanism 4 is moved forward while the traveling machine body 1 is stopped to perform the grading operation of the unaligned portion T, the grading mechanism 4 is moved backward by the reciprocating mechanism 7, and as shown in FIG. , Return to the original rear position, turn the traveling machine 1 90 degrees counterclockwise in FIG. 16, and after turning, the traveling machine 1 travels straight forward in the direction of the arrow to perform the straightening work, and again , The traveling machine body 1 comes to the front of the front eaves W, In the forward limit position, the travel of the traveling machine body 1 is stopped in the same manner as described above, and as shown in FIGS. 11, 12, and 13, the straightening mechanism 4 is moved forward by the reciprocating mechanism 7 while driving the straightening mechanism 4. By doing so, it is possible to perform the trimming operation of the unsorted portion T of the kite W, and when the traveling machine body 1 is stopped, the trimming mechanism 4 is moved forward to perform the trimming operation of the unsorted portion T. Thereafter, the straightening mechanism 4 is moved backward by the reciprocating mechanism 7 to return to the original rear position, and the traveling machine body 1 is turned counterclockwise by 90 degrees, and these are present on the four sides of the field M. By repeating the traveling machine body 1 in one direction along the four kites W in the counterclockwise direction, it is possible to arrange all four kites W continuously.

  Accordingly, it is not necessary to travel the traveling machine body 1 counterclockwise or counterclockwise in the opposite direction, so that it is possible to improve the alignment workability and to adjust the unaligned portion T. Since two types of trimming mechanisms, ie, a mechanism and a secondary trimming mechanism, are not required, the structure of the trimming mechanism 4 can be simplified and the manufacturing cost can be reduced.

  Further, the guide mechanism 6 uses a multi-stage sliding structure D in which a plurality of moving frames 6c and 6e slide in a stacked manner, and the reciprocating mechanism 7 includes a plurality of moving frames 6c and 6e. Since the hydraulic cylinders 7a and 7b are reciprocally moved independently of each other, a short stroke hydraulic cylinder can be employed, and the guide mechanism 6 and the reciprocating mechanism 7 can be downsized.

  In this case, the guide mechanism 6 uses a two-stage sliding structure in which the two moving frames 6c and 6e slide in a stacked manner in two stages, and the reciprocating mechanism 7 has two moving mechanisms. Since the two hydraulic cylinders 7a and 7b reciprocally move the frames 6c and 6e independently, the guide mechanism 6 and the reciprocating mechanism 7 can be reduced in size and simplified. As a rotational drive source of the trimming mechanism 4, a drive shaft 7 d that is rotated by the power take-off shaft 1 b of the traveling machine body 1 is installed in the machine frame 3 in the trimming work traveling direction. Can be simplified.

Further, in this case, since the rotary trimming body 5 is formed by arranging a plurality of pressing plate bodies E made of a flexible plate at intervals on the outer peripheral portion, as shown in FIG. As the traveling machine body 1 in the direction of the arrow 5 rotates in the direction that promotes the forward movement, the pressing plate E gradually tightens the embankment and is strongly pressed by the pressing portion G via the pressing plate E. The clamping area is reduced intermittently by the presence of the plurality of clamping parts G, and the clamping area is reduced by the presence of the plurality of clamping parts G as compared with the structure in which clamping is performed on the entire outer peripheral surface of the rotary adjuster 5. As a result, the clamping pressure can be increased, and the clamping plate E can be gradually clamped while the bending plate E is flexibly operated, so that the adhesion of the soil to the outer peripheral portion of the rotary trimming body 5 can be reduced. It can be suppressed, and the heel W can be tightened as much as that. Clamping plate member E of the rotating Seiaze member 5 by increasing the rotational speed of the Seiazetai 5 rotates sliding contact with ridge W surface, the upper surface W ₁ of one side W ₂ and ridge W of ridge W by sliding rotary contact Can be adjusted smoothly and firmly.

  Further, in this case, since the old dredge W surface can be cut in advance by the pretreatment mechanism 15 and the earthing mechanism 14 fills the earth on the cut dred W surface, the connection between the old dredge W soil and the embankment is performed. Wearability can be improved, and the strong wrinkle W can be obtained.

  The second embodiment shown in FIGS. 14 and 15 shows another example structure. In this case, a hydraulic motor 19 is provided in the machine frame 3 as a rotational drive source of the adjusting mechanism 4, and each port of the hydraulic motor 19 is provided. And the respective ports of the hydraulic pump 7c are connected via a flow path switching valve (not shown), and the hydraulic motor 19 and the drive shaft 7d installed in the direction of the trimming work are directly connected by a joint 20, and the hydraulic motor The drive shaft 7 d is rotated by 19, and is configured as a rotational drive source of the trimming mechanism 4.

  Therefore, in the second embodiment, as the rotational drive source of the trimming mechanism 4, a drive shaft 7d that is rotated by the hydraulic motor 19 is installed on the machine frame 3 in the trimming work advancing direction. The structure of the trimming mechanism 4 can be simplified.

  It should be noted that the present invention is not limited to the above-described embodiment, and the structure of the trimming mechanism 4, the guide mechanism 6, and the reciprocating mechanism 7 is changed as appropriate, for example, an electric cylinder is used instead of the hydraulic cylinder. Designed.

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