Good.

  Next, the details of the slope trimming plate 84 (the slope trimming plate 84A and the slope trimming plate 84B) provided in the slope trimming unit 82 will be described. FIG. 4 schematically shows a state in which the slope trimming section 82 formed by connecting a plurality of slope trimming plates 84 is in contact with the old hammer K. Although the slope trimming portion 82 is drawn flat and a plurality of trimming plates are in contact with the old hammer, the slope trimming portion 82 is actually in an arc shape around the rotation axis. It bends. Although FIG. 4 is drawn as an end view, even if it is an arbitrary cross-sectional view, it has the same shape. The same applies to FIGS. 5 to 8 below.

  As shown in FIG. 2, the slope adjusting portion 82 is formed in a truncated cone shape as a whole, and a connecting portion 86 connected to the upper surface adjusting portion 83 at the tip position (right end portion in FIG. 2) Projecting toward the trimming portion 83.

  On the outer peripheral surface of the slope adjusting section 82, a plurality of substantially fan shaped slope adjusting plates 84 are continuously provided radially around the rotation shaft 81, thereby forming a truncated cone shape. The slope trimming plate 84 is formed of, for example, a metal material such as stainless steel or a steel plate, or a synthetic resin such as polypropylene, polyethylene, or polyvinyl chloride, but is not limited thereto. .

  As shown in FIG. 4, the slope trimming unit 82 is configured such that a radial portion in a fan shape is continuously provided while a slope trimming plate 84 </ b> A and a slope trimming plate 84 </ b> B are alternately overlapped. In FIG. 4, this radius portion corresponds to the left and right end portions of the slope trimming plate 84A and the slope trimming plate 84B. The slope trimming plate 84A and the slope trimming plate 84B are both joint surfaces 843 having a predetermined step at the end in the rotation direction F side, and the slope trimming plate adjacent to the rotation direction F side. It joins with the inner surface of the edge part on the opposite side to the rotation direction F of the saddle plate 84B and the slope adjusting plate 84A.

  The slope trimming plate 84A is configured such that the distance from the rotation shaft 81 (corresponding to the rotation radius) increases from the end on the rotation direction F side toward the end on the opposite side. As a result, in the drawing, the rear side in the rotation direction F of the slope trimming plate 84A protrudes toward the old rod K, and the rear side of the projection of the slope trimming plate 84A in the rotation direction F The soil is pushed into the old wall and painted. Then, on the rear side of the projecting slope leveling plate 84A, a portion where the distance from the rotation shaft 81 is the largest (portion in contact with the flange surface K in FIG. 4) is a curved surface portion 841.

  The curved surface portion 841 is continuously provided at the rear of the rotation direction F from the position protruding outward, and a curved surface 841a is formed in which the distance from the rotation shaft 81 gradually decreases toward the opposite side of the rotation direction. Configured. The curved surface 841a is formed so that the distance from the rotation shaft 81 gradually decreases toward the rear in the rotation direction F (in the drawing, it is drawn so as to gradually move away from the flange surface), and is gently It has a circular arc shape. When the curved surface portion 841 is in contact with the old heel K, the curved surface 841a is continuously curved with the rotation of the slope adjusting portion 82 even after the top of the curved surface portion 841 that protrudes outward is in contact with the old heel K. The side touches the old fence K. Therefore, the continuous planar shape in the curved surface portion 841 operates so as to smear the old heel K, and the curved portion 841a gradually moves away from the old heel as the slope rectifying portion 82 rotates. This prevents scratch marks from remaining and makes it easier to finish the surface of the ridges into a smooth shape.

  The slope trimming plate 84B is configured such that the distance from the rotation shaft 81 increases from the end on the rotation direction F side toward the end on the reverse side (rear side in the rotation direction). Accordingly, in the drawing, the rear side in the rotation direction F of the slope trimming plate 84B protrudes toward the saddle surface, and the rear side in the rotation direction F of the projected slope trimming plate 84B Is pushed into the surface and painted. Then, on the rear side of the protruding slope grading plate 84B, in the slope grading plate 84A, a portion where the distance from the rotation shaft 81 is the largest is a curved surface portion 841 in which the curved surface 841a is formed. On the other hand, the slope trimming plate 84B is an edge portion 842 having no shape corresponding to the curved surface 841a.

  The edge portion 842 is an end portion facing the opposite side of the rotation direction F in the slope trimming plate 84B, and a position that protrudes most toward the heel side is an end surface 842a. And since the part which touches the old ridge K is not formed behind this end surface 842a in the rotation direction F, the distance from the rotating shaft 81 is gradually increased toward the opposite side of the rotation direction F. The end surface 842a is reached. As a result, when the edge portion 842 contacts the old fence K, the pressure on the old fence is concentrated on the end surface 842a formed at the most outwardly projecting position, and the soil can be strongly pushed into the fence. Note that the radial distance from the end surface 842a to the slope trimming plate 84A is larger than the radial distance from the end surface of the curved surface portion 841 to the slope trimming plate 84B.

  In this way, the slope trimming portion 82 includes a slope trimming plate 84A in which the curved surface portion 841 is formed at the rear portion in the rotation direction, and a slope trimming plate 84B in which the edge portion 842 is formed at the rear portion in the rotation direction. However, a plurality of slopes are provided alternately on the outer peripheral surface of the slope adjusting section 82. Therefore, when the slope trimming portion 82 rotates, the soil is pushed smoothly into the old hammer by the edge portion 842 of the slope shaping plate 84B, and the soil is smoothed into the old hammer by the curved surface portion 841 of the slope shaping plate 84A. Can be smeared on. As a result, the slope trimming part 82 makes it easy to form a ridge having a strong and smooth surface.

  In the present embodiment, the plurality of slope trimming plates 84 are connected to each other by a linear portion corresponding to a sector radius, but other than this, for example, as shown in FIG. You may attach without connecting. In this case, end portions 185 (185a, 185b) on the rotation direction side of the slope-grinding plates 184 (184A, 184B) are joined to the truncated cone-shaped base body 182. In the illustrated example, the slope trimming plate 184 is an example formed of a synthetic resin and is fastened to the base body 182 by a fastening member such as a screw, but when formed of a metal such as stainless steel, welding is performed. It may be joined by, for example. However, if the slope trimming plate 184 is detachably attached by a fastening member, even if the slope trimming plate 184 is worn or damaged, only the slope trimming plate 184 that has been worn is easily replaced. can do.

  Further, when attaching to the base body 182, the joining portion (end portion 185 b) of the slope rectifying plate 184 B and the curved surface portion 181 a of the slope rectifying plate 184 A, or the joining portion (end portion) of the slope rectifying plate 184 A. 185a) and the edge portion 181b of the slope trimming plate 184B are arranged so that adjacent end portions overlap each other. As a result, the joining portion of the slope trimming plate 184 with respect to the base body 182 is covered with the adjacent slope trimming plate 184, so that the joining portion does not contact the collar surface during work, and the surface of the collar is It is arranged in a smoother shape.

  In this embodiment, as shown in FIG. 4, the slope trimming plates 84A and the slope trimming plates 84B are alternately provided in the circumferential direction. A predetermined number of surface trimming plates 84A may be continuously provided in the circumferential direction, or a predetermined number of slope shaping plates 84B may be continuously provided in the circumferential direction. Further, either one of the slope shaping plate 84A and the slope shaping plate 84B may be provided.

(Embodiment 2)
FIG. 6 shows a schematic diagram of a slope trimming unit 282 constituted by a slope trimming plate 284 as a second embodiment. Note that the same or corresponding parts as those in the first embodiment are denoted by the same reference numerals as in FIGS. 1 to 5, and only the configuration different from that in the first embodiment will be described. Note that the slope trimming unit 282 in the second embodiment replaces the slope trimming unit 82 in the first embodiment. FIG. 6 schematically illustrates a state in which the slope trimming unit 282 configured by connecting a plurality of slope trimming plates 284 is in contact with the old kite K. FIG. Although the slope trimming portion 182 is drawn flat, it is actually curved in an arc shape around the rotation axis.

  On the outer peripheral surface of the slope adjusting section 282, a plurality of substantially fan-shaped slope adjusting plates 284 are continuously provided radially around the rotation shaft 81, thereby forming a truncated cone shape. The slope trimming plate 284 is formed of a metal material such as stainless steel or a steel plate, or a synthetic resin such as polypropylene, polyethylene, or polyvinyl chloride, but is not limited thereto. .

  The slope adjusting section 282 of the illustrated example is configured such that a plurality of adjacent slope adjusting plates 284 overlap with each other in a fan-shaped radius portion. The slope trimming plate 284 is a joint surface 284e having a predetermined step at the end on the rotation direction F side, and is opposite to the rotation direction F on the slope trimming plate 184 adjacent to the rotation direction F side. It is joined to the inner surface of the end portion on the side.

  The slope trimming plate 284 is configured such that the distance from the rotation shaft 81 (corresponding to the rotation radius) increases from the end on the rotation direction F side toward the end on the opposite side. Thereby, as it goes to the rear side in the rotation direction F in the drawing, the surface of the slope trimming plate 184 protrudes toward the old ridge K. In the vicinity of the intermediate position in the circumferential direction of the slope lining plate 184, a top portion (a portion in contact with the ridge surface K in FIG. 6) that protrudes outward is provided, and an edge portion 284b is formed here. The radius of rotation at the edge portion 284b gradually increases gradually from the rotation direction F side toward the opposite side, and this suddenly increases to a predetermined value with the end face 284d formed at the end facing the opposite side of the rotation direction F as a boundary. Decreases in size to form a step. As a result, the distance from the rotation shaft 81 gradually increases toward the end surface 284d in the direction opposite to the rotation direction F.

  And it is comprised so that the distance from the rotating shaft 81 may become large as it goes to the edge part on the reverse side from the position where the step part went down one step. Thereby, as it goes to the rear side in the rotation direction F in the drawing, the surface of the slope trimming plate 284 protrudes toward the old ridge K. Then, on the rear side of the protruding slope grading plate 284, a portion where the distance from the rotation shaft 81 is the largest (portion in contact with the ridge surface K in FIG. 6) is a curved surface portion 284a.

  The curved surface portion 284a is formed by forming a curved surface 284c that is continuously provided rearward in the rotational direction from a position that protrudes to the outermost side, and the distance from the rotational shaft 81 gradually decreases toward the opposite side of the rotational direction. Is done. The curved surface 284c is formed such that the distance from the rotation shaft 81 gradually decreases toward the rear in the rotation direction F (in the drawing, the curve surface 284c is drawn so as to gradually move away from the flange surface), and is gently It has a circular arc shape.

  In this way, a plurality of slope trimming plates 284 having an edge portion 284b formed at the intermediate position in the rotational direction and a curved surface portion 284a formed at the rear portion in the rotational direction are alternately arranged with respect to the outer peripheral surface of the slope trimming portion 282. Is provided. Therefore, when the slope trimming portion 282 rotates, the soil can be smoothly applied to the old hammer by the curved surface portion 284a, while the soil is firmly pushed into the old hammer by the edge portion 284b of the slope shaping plate 284. As a result, the slopes 282 are easy to form into a ridge having a strong and smooth surface.

  Further, unlike the first embodiment, since the slope trimming part is constituted by one kind of slope trimming plate, the number of parts can be reduced, the cost can be reduced, and the assembly can be facilitated.

  In the present embodiment, the plurality of slope trimming plates 284 are connected to each other by a straight line portion corresponding to a sector radius, but other than this, for example, as shown in FIG. You may attach without connecting. In this case, the end portion 385 on the rotational direction side of the slope grading plate 384 having the curved surface portion 381 and the edge portion 383 is joined to the truncated cone-shaped base body 382. The illustrated example is an example in which the slope trimming plate 384 is formed of a synthetic resin, and is fastened to the base body by a fastening member such as a screw. May be joined together. However, if the slope trimming plate 384 is detachably attached by a fastening member, even if the slope trimming plate 384 is worn or damaged, only the slope trimming plate 384 that has been worn is easily replaced. can do.

  Further, when attaching to the base body 382, adjacent end portions such as the curved surface portion 381 of the slope adjusting plate 384 adjacent to the joint portion (end portion 385) of the slope adjusting plate 384 overlap each other. Are arranged as follows. As a result, the joining portion of the slope trimming plate 384 with respect to the base body 382 is covered by the adjacent slope trimming plate 384, so that the joining portion does not touch the collar surface during work, and the surface of the collar is It is arranged in a smoother shape.

  In this embodiment, one curved surface shaping plate is formed with one curved surface portion and one edge portion. However, the present invention is not limited to this. For example, a plurality of edge portions may be formed. Further, the edge portion may be formed at the end opposite to the rotation direction, and the curved surface portion may be formed at an intermediate position in the rotation direction. In this case, a plurality of curved surface portions may be formed.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the design can be changed without departing from the scope of the present invention. Is included in the present invention. Furthermore, the above-described embodiments can utilize each other's technology as long as there is no particular contradiction or problem in the purpose, configuration, or the like. For example, the slope trimming plate 284 according to the second embodiment may be inserted between the slope trimming plate 84A and the slope trimming plate 84B according to the first embodiment.

  In addition, the present invention can be applied to the upper surface adjusting portion 83 in order to adjust the upper surface of the ridge to a shape that is strong and has a smooth surface. In this case, in the end view (cross-sectional view) perpendicular to the rotation shaft 81, the shape of each upper surface trimming plate 85 is formed to be the same shape as the slope trimming plate 84 and the like. For example, the rear side of the upper surface trimming plate 85 in the rotational direction of the upper surface trimming portion 83 protrudes outward from the outer peripheral surface of the upper surface trimming portion 83, and the soil is removed by the rear portion of the projected upper surface trimming plate 85. It is pushed onto the old wall and painted. Then, either a curved surface portion or an edge portion is formed in the rear portion of the protruding upper surface trimming plate 85.

  When the curved surface portion and the edge portion are formed with respect to the upper surface adjusting portion as described above, it is optional to provide the curved surface portion and the edge portion with respect to the slope adjusting portion, and the upper surface adjusting portion. The curved surface portion and the edge portion may be formed only on the upper surface, or the curved surface portion and the edge portion may be formed on both the upper surface adjusting portion and the slope adjusting portion.

  Moreover, in this embodiment, although the thickness of the member of each part is formed substantially the same in the slope trimming plate and the upper surface trimming plate, the thickness may be partially changed. For example, as shown in FIG. 8, the thickness of the curved surface portion 484a and the edge portion 484b of the trimming plate 484 can be made thicker than that of the other portions. In this case, when soil is pushed in and applied to the old paddle K, pressure can be applied more easily than other portions, and the strength of the portions that easily wear (curved surface portion 484a and edge portion 484b) can be increased.
