  That is, for example, if there is no claw guard 44, as shown by a two-dot chain line in FIG. 5, soil adheres to the inner surface of the rear plate 9, but if there is a claw guard 44 as in this embodiment, The soil does not grow on the inner surface of the rear plate 9 and hardly adheres to the vicinity of the outer periphery of the rear boss 33 on the inner surface of the rear plate 9.

  And according to this cocoon coating machine 1, the embankment body 3 which plows and raises soil while rotating in a predetermined direction covers the bent portion 39 of the bent tillage nail 40 and the nail holder portion 36 of the tillage shaft 31. 44, the bent tillage claw 40 can be prevented from being bent and deformed even when the bent tillage claw 40 is largely bent at the bent portion 39, and the bent tillage claw 40 can be prevented from being bent and deformed. Wear of the nail holder portion 36 can be prevented.

  Further, the claw guard 44 can suppress the soil from adhering to the portion of the inner surface of the rear plate 9 of the cover body 6 located in the vicinity of the tilling shaft 31, and can prevent the soil crushing property from being deteriorated by the adhered soil.

  In addition, since the claw guard 44 is fixed to the bent portion 39 of the bent tillage claw 40, the bent tillage claw 40 is reinforced by the nail guard 44 to improve the strength, and the bent tillage claw 40 is effectively bent and deformed. Can be prevented.

  In the above embodiment, the configuration in which the claw guard 44 is bent and fixed to the tilling claw 40 by welding or the like has been described. For example, as shown in FIGS. 8 and 9, the claw guard 44 has a claw holder of the tilling shaft 31. The configuration may be such that the unit 36 is detachably attached to the part 36 together with the bending tillage claw 40 by the attaching means 55.

  The attaching means 55 is, for example, a bolt 56 and a nut 57 for attaching a claw. Further, a pair of mounting plate portions 58 that are spaced apart from each other are projected from the second plate portion 47 of the claw guard 44, and mounting holes 59 are formed in the mounting plate portions 58.

  Then, a bolt 56 is inserted into the mounting hole 59 of the claw guard 44, the mounting hole 61 of the claw holder portion 36, and the mounting hole 62 of the bent tillage claw 40, and a nut 57 is inserted on the tip side of the inserted bolt 56. Are screwed together so that both the claw guard 44 and the bent tillage claw 40 are attached to the claw holder 36 at the same time. For example, when the claw guard 44 is worn and needs to be replaced, only the claw guard 44 can be replaced.

  There is a gap 60 between the first plate portion 46 of the claw guard 44 and the bent portion 39 of the bent tillage claw 40. For example, the first plate portion 46 is bent to the bent portion 39 so that the gap 60 does not exist. You may make it contact | abut.

  In any of the embodiments, the claw guard 44 is not limited to a plate shape having a square shape when viewed from the front, and the shape thereof is arbitrary, and may be, for example, a curved plate shape.

  Further, for example, a guard attaching portion may be provided on the outer peripheral surface of the shaft portion 35 of the tilling shaft 31, and the claw guard 44 may be detachably attached to the guard attaching portion.

  The claw guard 44 may cover only the bent portion 39 of the bent tillage claw 40, for example.
