It is located in front of the front plate 21. Further, a bar-shaped member 77 partially bent along the arc-shaped plate 72 is fixed to the upper surface of the arc-shaped plate 72, and a straight portion of the bar-shaped member 77 serves as an insertion portion 78 for attachment. . A substantially U-shaped gripping member 79 is fixed to the curved portion of the rod-shaped member 77.

  Then, the insertion portion 78 of the rod-shaped member 77 of the auxiliary cover body 52 is removably fitted into the insertion hole 30 of the mounting member 31 of the support frame portion 13 of the movable machine frame 9 of the machine body 2, and this inserted insertion. By pressing the presser bolt 57 of the fixture 54 onto the portion 78, the rod-like member 77 of the auxiliary cover body 52 is attached to the attachment member 31 of the support frame portion 13.

  When the auxiliary cover body 52 is removed from the support frame portion 13, the presser bolt 57 is loosened, and then the insertion portion 78 of the rod-shaped member 77 is pulled out from the insertion hole 30 of the attachment member 31 of the support frame portion 13.

  Note that, on the outer end side of the auxiliary cover body 52, an upper surface guide plate 80, which is a guide body that moves along the upper surface of the saddle, is attached (see FIG. 1).

  On the other hand, as shown in FIG. 1 and FIG. 3, the wrinkle coater 1 is detachably attached to the support frame portion 13 of the machine body 2 and is supported by the support frame portion 13 to scrape the upper surface of the main rod. Sharpening means 81 is provided.

  The upper surface shaving means 81 has a frame 83 attached to the upper plate 24 by means of a fixture 82 such as a bolt inserted into the attachment hole 29 of the upper plate 24 of the support frame 13. A moving cylindrical body 84 is attached to be rotatable about a shaft 85. A rod 86 is movably inserted into the rotating cylindrical body 84, and one end of a transmission case 88 such as a chain case is connected to the tip of the rod 86 via a connecting member 87. An extension rotary shaft 41a connected to the front end portion of the rotary shaft 41 of the embankment 3 is inserted into the other end portion of the transmission case 88. A spring 89, which is a biasing means, is mounted on the outer peripheral side of the rod 86 in a state where it is positioned by a pin 90.

  Further, the saddle face shaving means 81 is connected to the extension rotary shaft 41a of the embankment body 3 and is driven in a predetermined direction by power from a transmission means (not shown) such as a chain housed in a transmission case 88. The rotation shaft 91 is provided. The rotating shaft 91 is supported in a cantilevered state so as to be rotatable at one end portion of the transmission case 88. The rotating shaft 91 has a plurality of claw holder portions 92 on the outer peripheral side, and each claw holder portion 92 includes a rotating shaft. A tilling claw 93 which cultivates the top surface of the main fence while rotating in a predetermined direction together with 91 and cultivates the tilled soil on the top surface of the main fence is detachably attached. The plurality of tilling claws 93 are covered with a cover body 94.

  On the other hand, as shown in FIG. 1, the bag forming body 4 is rotatably supported by a transmission frame portion 14 of a movable machine frame 9 of the machine body 2 and is driven to rotate in a predetermined direction by power from the intermediate input shaft 15 side. Rotating shaft 101 and a substantially frustoconical ridge that forms an inclined side surface that is inclined downward toward the surface of the rice field by compacting the embankment by the tilling claws 47 while rotating about the rotation axis X together with the rotating shaft 101 A horizontal plane top surface of the side surface forming body 102 and the horizontal surface of the side surface forming body 102 which is provided on the diameter-reduced side end portion of the side surface forming body 102 and rotates around the rotation center axis X together with the rotary shaft 101 And a substantially cylindrical ridge upper surface forming body 103. Further, the heel side surface forming body 102 is covered with a cover body 104.

  In addition, the peripheral speed of the ridge forming body 4 is set to a value faster than the traveling speed of the tractor so that the ridge forming body 4 rotates in a slip state with respect to the heel side surface and the heel surface.

  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 rotary shafts 41, 91, and 101 are driven to rotate. .

  When these rotary shafts 41, 91, 101 are driven and rotated, the soil is raised by the tilling claws 47, 93 on the side surface and the top surface of the main fence, and on the side surface forming body 102 that rotates by slipping about the rotation center axis X. Thus, the embankment is compacted to form a sloped ridge side surface, and the embankment is compacted by a heel surface forming body 103 that rotates by slipping about the rotation center axis X to form a horizontal surface of the ridge surface. .

  Here, for example, when exchanging the tilling claws 47 of the embankment body 3 and removing the soil adhering to the inner surfaces of the cover body 51 and the auxiliary cover body 52, or when the cover body 51 and the auxiliary cover body 52 are damaged. To replace it with a new one, remove the nut 56 of the fixture 53 from the bolt 55, remove the bolt 55 from the mounting holes 23 and 64, and cover the space between the front plate 21 and the rear plate 22 of the support frame portion 13. The cover body 51 is removed from the support frame portion 13 so that the body 51 is pulled out sideways. Further, after loosening the presser bolt 57 of the fixture 54, the auxiliary cover body 52 is attached to the support frame by pulling the insertion portion 78 of the rod-shaped member 77 laterally from the insertion hole 30 of the attachment member 31 of the support frame portion 13. Remove from part 13. That is, the cover body 51 and the auxiliary cover body 52 can be detached from the support frame 13 of the body 2.

  In addition, according to such a hull coater 1, not only can the rotary shaft 41 of the embankment 3 be stably supported by the support frame portion 13 of the movable machine frame 9 of the machine body 2 while being supported, Exchange work, removal work of soil adhering to the inner surface of the cover body 51, removal work of soil attached to the inner surface of the auxiliary cover body 52, and the like can be easily performed.

  Even when the cover body 51 and the auxiliary cover body 52 are damaged, it is sufficient to replace only the cover body 51 or only the auxiliary cover body 52, thereby reducing the burden on the user.

  Furthermore, the degree of freedom in the shape design of the cover body 51 and the auxiliary cover body 52 is increased, and it becomes easy to improve the function and performance and cope with various conditions.

  In the above-described embodiment, the structure in which the cover body 51 and the auxiliary cover body 52 are detachably attached to the support frame portion 13 has been described. It is also possible to adopt a configuration in which only the cover body 51 is detachably attached.

  For example, although not shown, the cover body 51 may be divided and configured by a plurality of cover body forming members, or a grip member may be provided so that the cover body 51 can be easily attached and detached.
