  Each ridge upper surface forming surface portion 44 has an elongated and substantially rectangular shape, and is formed in a spiral shape that is twisted so as to be directed in the direction opposite to the rotation direction a of the ridge upper surface formation body 25 toward the heel side surface formation body 24 side. Yes. Each of the upper surface forming surface portions 44 is formed in a curved surface shape such that the center in the width direction is convex toward the side opposite to the rotation center axis X side. Although not shown, each of the upper surface forming surface portions 44 may have a planar shape instead of a curved surface shape.

  Each of the upper surface forming surface portions 44 can change between a first state where the distance from the rotation center axis X side is long and a second state where the distance from the rotation center axis X side is short. At the time of contact with the soil at the time, the upper surface forming body 25 moves to the rotation center axis X side and changes from the first state to the second state.

  Here, each collar upper surface forming surface portion 44 is configured by an elastic plate 45 which is a plate that can be elastically deformed, for example. The elastic plate 45 is a resin plate or metal plate having a predetermined shape shown in FIGS. 6 and 7, and a plurality of (for example, three) through holes 46 are formed at one end along the longitudinal direction.

  Then, as shown in FIG. 8, the front end portion in the rotational direction of the elastic plate 45 is detachably attached to the attachment plate portion 41 by attachment means 47 made of, for example, bolts inserted into the screw holes 42 and the through holes 46. The rear end portion in the rotation direction of the elastic plate 45 is a free end portion 45a. In addition, the elastic plate 45 is inclined so that the distance from the rotation center axis X becomes longer toward the free end 45a before the elastic plate 45 is elastically deformed by contact with the soil. That is, each elastic plate 45 is radially centered about the rotation center axis X before elastic deformation.

  Furthermore, the collar upper surface forming body 25 comes into contact with the elastic plate 45 which is the collar upper surface forming surface portion 44 in a plane and moves based on the elastic deformation of the elastic plate 45 itself toward the rotation center axis X side of the elastic plate 45. By restricting, the step 50 between the elastic plates 45 adjacent to each other in the rotation direction a, that is, the free end portion 45a of the elastic plate 45 elastically deformed, and the one elastic plate 45 and the rotation direction a are adjacent to each other in the opposite direction. It has a stopper portion 51 that maintains a step 50 having a predetermined dimension with the front end portion (attachment end portion) of the other elastic plate 45 in the rotation direction. The stopper portion 51 is provided corresponding to each elastic plate 45, and each stopper portion 51 is constituted by a pair of stopper surfaces 35a and 37a.

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

  When the spreader 1 is connected to the three-point link at the rear of the tractor and the tractor is run, the spreader 1 moves forward in the traveling direction together with the tractor, and the embankment body 3, the hull forming unit 4, and the upper surface cutting unit. Each of 5 rotates.

  Then, the earth is raised by the embankment body 3 on the reed side and reed upper surface of the main reed, and the reed is formed at the reed side surface forming surface portion 32 of the reed side surface forming body 24 that rotates in the rotation direction a about the rotation center axis X. The clay is compacted to form the inclined side surface B, and the soil is compacted by the top surface forming surface portion 44 of the top surface forming body 25 that is driven to rotate in the rotation direction a about the rotation center axis X. An upper surface C is formed.

  At this time, the elastic plate 45 constituting the ridge upper surface forming surface portion 44 is folded in the middle toward the rotation center axis X side by the weight of the ridge forming portion 4 or the like at a position in contact with the soil raised on the upper surface of the ridge. It bends and elastically deforms so as to bend, comes into contact with the stopper surfaces 35a and 37a of the stopper portion 51, and is substantially along a virtual circle centered on the rotation center axis X. And between the free end portion 45a of this elastically deformed one elastic plate 45 and this elastic plate 45 and the front end portion in the rotation direction of another elastic plate 45 adjacent to the opposite direction to the rotation direction a, there is a predetermined amount. The level difference 50 is maintained, and the elastic plates 45 adjacent to each other are not in contact with each other and remain in non-contact.

  For this reason, the soil striking effect is exhibited by the step 50 having a predetermined dimension, and the soil is sufficiently compacted by the elastic plate 45. Further, since the elastic plate 45 is in a state substantially along the tangential direction of the virtual circle centering on the rotation center axis X before the elastic deformation, a desired amount of soil is scraped by the elastic plate 45. Further, since the elastic plate 45 has a predetermined spiral shape, the soil moves toward the reduced diameter side end portion of the heel side surface forming body 24 in the elastic plate 45, and near the reduced diameter side end portion of the heel side surface forming body 24. Is supplied with the desired amount of soil.

  Therefore, according to such a plastering machine 1, a sufficient earth compaction force can be obtained by the kite surface forming body 25 even under difficult conditions such as soil with little moisture, and the kite upper surface having a desired hardness can be obtained. C (including the shoulder) can be formed, and thus a strong ridge A that is difficult to collapse can be formed.

  In the above embodiment, the case where the heel upper surface forming surface portion 44 is configured by the elastic plate 45 which is a spiral-shaped face body has been described. However, as in the other embodiment shown in FIG. 9, for example, Even if the formation surface portion 44 is configured by a non-elastic plate (rigid plate) 55 that is a spiral-shaped surface body that cannot be elastically deformed, the same effect can be obtained.

  9, the front end portion in the rotational direction of the inelastic plate 55 is attached to the attached plate portion 41 via a connecting elastic body 56 that can be elastically deformed, and the rear end portion in the rotational direction of the inelastic plate 55 is free. It is an end 55a. The connecting elastic plate 56 is substantially L-shaped having a first plate portion 57 and a second plate portion 58, and the first plate portion 57 is attached to the attached plate portion 41 by attachment means 47 made of bolts or the like. The second plate portion 58 is attached to the front end portion in the rotational direction of the inelastic plate 55 by attachment means 59 made of bolts and nuts.

  9, the stopper portion 51 is brought into contact with the non-elastic plate 55 which is the upper surface forming surface portion 44 in a planar shape, and the elastic plate 56 which is connected to the rotation center axis X side of the non-elastic plate 55 is provided. The step 50 between the elastic plates 45 adjacent to each other in the rotation direction a is maintained by restricting the movement based on the bending elastic deformation.

  In any of the embodiments, the configuration is not limited to the configuration in which the mounting plate portion 41 is attached to the outer peripheral surface of the base portion 33 by welding or the like. For example, the mounting plate portion 41 is integrated with the outer peripheral side of the base portion 33. The structure etc. which were formed in may be sufficient.

  Furthermore, the number of the upper surface forming surface portions 44 is not limited to eight, but may be six or ten or more, and is arbitrary.
