<P>PROBLEM TO BE SOLVED: To provide a levee plastering machine having a front processing unit which is hardly damaged and which has the excellent capability of crushing soil and a high soil gathering effect. <P>SOLUTION: The levee plastering machine includes: the front processing unit 61 attached to a travelling machine body at a position offset sideways relative to the travelling position of the travelling machine body for leveling down an old levee and banking soil; and a levee shaping unit for plastering the banked soil over the old levee. The front processing unit 61 includes first tilling tines 67 and second tilling tines 69' in a plurality of rows at prescribed intervals in the axis direction of a tilling shaft 62 rotatably supported. These tines have a vertical blade 67b or 69b, and a horizontal blade 67c or 69c. The tines are curved in the direction opposite from the direction of rotation from the vertical blade to the horizontal blade, and the horizontal blade is curved to one side relative to the vertical blade. The first tilling tine 67 in the last row has the horizontal blade 67c facing the front side in the direction of the axis of the tilling shaft 62, and the second tilling tine 69' in the second row has the horizontal blade 69c facing the rear side in the direction of the axis. These tilling tines are disposed to face each other, and a soil holding space 72 is formed between the tilling tines for holding the soil so that the soil can be conveyed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
