Roller) 25.

  Note that the rotary shaft 23 of the heel forming portion 4 is driven to rotate in a predetermined direction by the power from the input shaft 11 side. The line passing through the axis of the rotation shaft 23 is the rotation center axis X.

  Here, as shown in FIGS. 2 to 8, the heel side surface forming body 24 is formed of a plurality of fan-shaped (for example, eight) metal heel side surfaces arranged in the rotation direction of the heel side surface forming body 24. A plate 31 is provided. The plurality of eaves side surface forming plates 31 are fixed to the outer peripheral surface of a base member 32 that is detachably attached to the rotary shaft 23, and are positioned radially about the rotation center axis (rotation shaft 23) X.

  Each saddle-side surface forming plate 31 is positioned so that the distance from the rotation center axis X gradually increases from the rotation direction front end side toward the rotation direction rear end side so that the soil is gradually pushed in at the rotation direction rear end side. ing. Therefore, a step (upper and lower intervals) 33 having a predetermined dimension exists between the side surface forming plates 31 adjacent to each other (see FIG. 7).

  That is, with respect to both side surface forming plates 31 adjacent to each other, the front end portion in the rotational direction of one side surface forming plate (back side surface forming plate on the rear side in the rotational direction) and the other side surface forming plate (front side in the rotational direction) The rear end portion in the rotation direction of the side surface forming plate 31 is connected by a connecting member 34 for holding a step difference in the shape of an elongated plate without overlapping each other (may overlap).

  The heel upper surface forming body 25 can be elastically deformed by a plurality of pieces (for example, eight sheets having the same number as the heel side surface forming plate 31) arranged in the rotation direction of the heel upper surface forming body 25 in a state where adjacent ones partially overlap each other. A vane plate (elastic plate) 41, which is a synthetic resin ridge upper surface forming plate, is provided. The plurality of blades 41 are detachably attached to an outer peripheral surface of an attachment cylinder 42 which is a cylindrical base member by a plate-like attachment member 43.

  The mounting cylinder 42 is connected to the base member 32 of the side surface forming body 24 by a connecting bolt 45. On the outer peripheral surface of the mounting cylinder 42, a plurality of mounting grooves 46 that form a set of four are formed. Similarly, each vane plate 41 has mounting holes 47 that form a set of four. Multiple sets are formed. The attachment member 43 is composed of an elongated plate portion 43a and claw portions 43b projecting from four locations of the plate portion 43a.

  Then, by inserting the claw portion 43b of the mounting member 43 through the mounting hole 47 of the blade plate 41 into the mounting groove 46 of the mounting tube 42, the blade plate 41 is detachably mounted to the mounting tube 42. Yes. Further, the vane plate 41 is positioned and fixed with respect to the mounting cylinder 42 by mounting the disk-shaped fixing plate 50 to the end face of the mounting cylinder 42 by the mounting bolts 49. The blade 41 can be removed from the mounting cylinder 42 by removing the mounting member 43 and the fixing plate 50.

  Each vane plate 41 for forming the upper surface is formed integrally with a slightly longer plate shape having a longitudinal direction in a direction inclined with respect to the rotation center axis X in a plan view, for example, by a synthetic resin plate. .

  Each blade 41 is connected to a main body plate 51 that overlaps the mounting cylinder 42 in a plan view, and an end (inner end) on the side surface forming body 24 side of the main plate 51, It has the transition part 52 which is an overlap part which overlaps with a part of the side surface forming plate 31 of the side surface forming body 24 in a side view.

  That is, the blade 41 is formed from the main body plate portion 51 that covers the outer surface of the mounting cylinder 42 and the inner end portion of the main body plate portion 51 so as to cover the outer surface of the end surface of the heel side surface forming plate 31 on the heel upper surface forming body 25 side. It is comprised by the transition part (bulging part) 52 which bulges toward the heel side surface formation body 24 side.

  The main body plate 51 has a front end portion in the rotation direction attached to the outer peripheral surface of the attachment tube 42 by the attachment member 43, and a rear end portion in the rotation direction separated from the outer peripheral surface of the attachment tube 42. That is, the main body plate portion 51 is positioned such that the distance from the rotation center axis X gradually increases from the rotation direction front end side toward the rotation direction rear end side so that the soil is gradually pushed in at the rotation direction rear end side. ing. A plurality of sets of mounting holes 47 are formed at the front end of the main body plate 51 in the rotation direction.

  The transition portion 52 is shaped so that the amount of overlap with the side surface forming body 24 (the amount of bulging toward the side surface forming body 24) gradually decreases from the front end side in the rotational direction toward the rear end side in the rotational direction. ing. That is, the transition portion 52 has a shape that approaches (protrudes) from the heel surface forming body 24 side (mounting cylinder 42 side) to the heel side surface forming body 24 side from the rotation direction rear end side to the rotation direction front end side. The overlapping amount of the transition portion 52 of the blade 41 and the side surface forming plate 31 gradually decreases from the front end side in the rotational direction toward the rear end side in the rotational direction.

  Then, the rotational direction front end portion 52a of the transition portion 52 approaches the step 33 of the side surface forming body 24, and one side surface forming plate (rotation) of the side surface forming plates 31 that are adjacent to each other through the step 33. In the vicinity of the front end portion in the rotational direction of the heel side surface forming plate 31 of the rear side in the direction, it is positioned so as not to contact the outer surface of the front end portion in the rotational direction before elastic deformation.

  For example, although not shown, the rotation direction front end 52a of the transition portion 52 may be in contact with the rotation direction front end outer surface of the side surface forming plate 31 before the elastic deformation (when not working). . Further, the rotational direction front and rear position of the rotational direction front end 52a of the transition part 52 may coincide with or slightly deviate from the rotational front and back position of the rotational direction front end of the side surface forming plate 31.

  Further, at least the front end side of the rotation direction front end portion 52a of the transition portion 52, that is, for example, the triangular front end side of the rotation direction front end portion 52a (in FIG. 4, the blade front end portion which is a triangular portion shaded) The other side surface forming plate 31 (the front side surface forming plate on the front side in the rotational direction) 31 of the side surface forming plates 31 adjacent to each other is positioned so as not to protrude from the rear end portion in the rotational direction.

  FIG. 7A shows a state before the blade plate 41 is elastically deformed, and FIG. 7B shows an outer surface (surface) of the heel side surface forming plate 31 because the blade plate 41 is elastically deformed by earth pressure during work. ) Shows a state of contacting the outer surface along the outer surface.

  As apparent from FIG. 7, the shape of the transition portion 52 changes depending on the earth pressure during work and during non-work. However, the rotation direction of the transition portion 52 is either during work or non-work. At least the front end side portion of the front end portion 52a is positioned so as not to protrude further toward the heel side than the rear end portion (the virtual circle a shown in FIG. 7) of the heel side surface forming plate 31 in the rotation direction.

  In other words, at least the tip end side (for example, only the tip end side) of the rotation direction front end portion 52a of the transition portion 52 of the blade plate 41 is always located on the inner side (reverse side) of the virtual circle a, It does not come out of the step 33 of the formed body 24. It should be noted that substantially the entire rotation direction front end portion 52a of the transition portion 52 may always be located on the inner side of the virtual circle a.

  The virtual circle (convex line) a is a circle centered on the rotation center axis X and connects the rear end portions (convex portions) in the rotation direction of the plurality of side surface forming plates 31. Note that the rear end side in the rotation direction of the transition portion 52 is formed, for example, in a convex curved shape toward the heel side, and its apex portion protrudes toward the heel side from the virtual circle a.

  Further, as shown in FIG. 4 and the like, the rotational direction rear end portion 52b of the transition portion 52 of the blade plate 41 is formed in, for example, a curved shape (including an arc shape). That is, for example, the end edge of the rear end portion 52b in the rotation direction of the transition portion 52 is a curved edge 52b1 that protrudes outward.

  As is clear from FIG. 4, the rotational direction front end portion 52 a of the transition portion 52 protrudes forward in the rotational direction from the rotational direction front end portion 51 a of the main body plate portion 51. 4 is a boundary line between the main body plate portion 51 and the transition portion 52.

  Next, the operation and the like of the above-described glazing machine 1 will be described.

  When the tractor 1 is connected to the three-point link at the rear of the tractor and the tractor travels, the trouser 1 moves in the traveling direction together with the tractor, and the embankment body 3, the ridge forming portion 4, and the upper surface shaving portion 5. Each rotate.

  Then, the soil cultivated by the embankment body 3 is raised to the main fence, and behind that, the soil is compacted by the dredge side face forming plate 31 of the dredge side face forming body 24 to form an inclined dredge side face. At the same time, the soil is compacted by the blades 41 of the ridge upper surface forming body 25 to form a horizontal ridge upper surface.

  At this time, the vane plate 41 of the heel surface forming body 25 is intermittently elastically deformed by earth pressure, and substantially all of the transition portion 52 is in close contact with the outer surface of the heel side surface forming plate 31 by this elastic deformation.

  Then, according to such a scissor coater 1, the vane 41 of the scissor upper surface forming body 25 has the transition part 52 that overlaps with the scissor side surface forming body 24, and this transition part 52 overlaps with the scissor side surface forming body 24. Since the amount decreases from the front end in the rotational direction toward the rear end in the rotational direction, the trimming performance of the upper surface portion and the shoulder portion is improved, and the shoulder portion is particularly curved. It is possible to form a strong ridge that can be compacted and thus not easily collapsed.

  Further, at least the front end side of the front end portion 52a in the rotational direction of the transition portion 52 of the vane plate 41 is always within the step 33 so that it does not protrude further toward the rear side than the rear end portion (virtual circle a) of the side surface forming plate 31 Therefore, it is difficult for the heel to be streaked, and it is possible to appropriately form a strong heel that does not collapse.

  Furthermore, since the rotational direction rear end portion 52b of the transition portion 52 of the vane plate 41 is formed in a curved shape, it is possible to appropriately form a strong heel that is less likely to collapse and has little pressure change applied to the heel.

  In the above-described embodiment, the configuration in which the blade plate 41 is attached to the attachment cylinder 42 by the plate-like attachment member 43 has been described. For example, as illustrated in FIG. The blade plate 41 may be attached to the attachment cylinder 42 by screwing and tightening the attachment bolt 56.

  For example, as shown in FIG. 10, the shape of the rear end 52b in the rotational direction of the transition portion 52 of the blade 41 may be a polygonal shape. That is, for example, the edge of the rear end portion 52b in the rotation direction of the transition portion 52 is a bent edge 52b2 bent at a plurality of locations.

  Further, the wing plate (elastic plate) 41 which is the upper surface forming plate is not limited to a synthetic resin plate, and may be a metal plate or a rubber plate that can be elastically deformed, for example.

  Further, the heel upper surface forming plate may be, for example, one that is not elastically deformed and that is rotatably provided on the mounting cylinder 42.

  Furthermore, the number of the upper surface forming plate and the upper surface forming plate is not limited to eight, and may be six or ten or more and is arbitrary.
