<P>PROBLEM TO BE SOLVED: To provide a harvester for harvesting crops cultured on a ridge covered with a mulch sheet while preventing winding of the mulch sheet to a side of a soil knock-off wheel. <P>SOLUTION: The harvester 1 includes a soil knock-off part 11 to knock off soil on a root of the crop with the soil knock-off wheel 36 under the middle part of a transfer conveyor 7 to transfer the crop backward while clamping the leaf and stem of the crop and pulling off the crop, and a sheet pressing part 9 to prevent winding of the mulch sheet S to the side of the transfer conveyor 7 by pressing the mulch sheet S with a roller 46. The winding of the mulch sheet S to the side of the soil knock-off wheel 36 is prevented by contacting the roller 46 with the soil knock-off wheel 36 to restrict the lifting motion and rotating the roller 46 downward reverse to the rotation of the soil knock-off wheel 36 when the roller 46 of the sheet pressing part 9 is lifted from a sheet rolling posture to a winding prevention posture. <P>COPYRIGHT: (C)2012,JPO&INPIT |
