Description

  The present invention includes a first leveling plate supported to be pivotable in the vertical direction behind the scraping rotor, and a second leveling plate supported to be pivotable in the vertical direction at a rear end portion of the first leveling plate. The present invention relates to a scraper working machine.

  It is known that when cultivating rice plants, straw, wheat straw, grass, etc. existing in the field, these humus are promoted and a better soil is produced. If this scrubbing work is done manually, it is hard work, especially when the field becomes very large. For this reason, a scraping work machine in which the plowing work is mechanized has been developed (see Patent Documents 1 and 2).

  The scraper working machine described in Patent Document 1 is a large rake attached to the back surface of the first leveling plate and extending obliquely downward between the scraping rotor and the first leveling plate toward the rear side, and a second leveling plate. There is a small rake attached to the back of the hood and extending backward. A plurality of these rakes are provided at predetermined intervals in the left-right direction with respect to the traveling direction of the scraping work machine, and these large and small rakes scissors that are present in the field during the scraping work are inserted into the field. .

  In addition, the scraping work machine described in Patent Document 2 has a plurality of predetermined intervals in the left-right direction with respect to the traveling direction of the first leveling plate at the middle portion in the front-rear direction of the first leveling plate (level plate in the document). Holes (guide long grooves in the literature) are provided, and disk-like discs are rotatably supported in these holes. The lower side of the disk protrudes downward from the back surface of the first leveling board, and soot and the like existing in the field are driven into the field.
