The left and right sward rods (12) that are projected further forward than the left shunt rod (12) are provided so that they can run close to or on the soil surface, and the front side of the left shunt rod (12) is used as a fulcrum to extend the rear side for an arbitrary length. An oscillating pipe (13) is extended so as to be in an obliquely upward position, and the oscillating pipe (13) is oscillated by a oscillating rod (14) at an arbitrary angle to separate uncut mow grass. A reciprocating cutting blade (15) of arbitrary cutting width is provided in the left and right direction so that it can approach the soil surface at the base of the right and left weeding rods (12), and right and left with the upper part immediately after the cutting blade (15) as the starting end. A vertical conveyor device (16) that holds and conveys the stalk stalk base side part in which a flat belt of arbitrary width is stretched vertically is extended to the rear part of the machine body (14),
Through the transfer transmission case (17) provided on the upper right front end of the vertical transfer device (16), the stalk basal side is attached to the front side by a lug attached to the endless body by inclining to a position where it can approach the soil surface. A scraping device (18) for scraping the portion was provided, and the rear side was attached to the endless body so that the rear side was in a slanting position over the length corresponding to the vertical conveying device (16). Provided with an ear tip feeding device (19) adapted to convey the straw grass in an upright state by a lug, and the vertical feeding device (16) at a substantially intermediate position between the tip feeding device (19) and the vertical feeding device (16). An intermediate feeding device (20) using a lug belt is provided in parallel. A fulcrum shaft (21) provided at the lower rear position of the reaping and conveying section (7) is supported by a bearing section provided on the traveling frame (5), and a weeding rod (12) of the reaping and conveying section (7).
Also, the cutting blade (15) is caused to be vertically rotatable by a hydraulic device so as to approach or approach the soil surface. At the vertical position of the tip feeding device (19) and the intermediate feeding device (20) at an intermediate position, the vertical conveying device (16) held the ears side of the strawberries that had been conveyed upright and hung it. In this state, a horizontal conveyor device (22) in which a flat belt of arbitrary width is stretched in the vertical direction before and after further conveying to the right is extended to the right side of the machine body (4), and the lateral conveyor device (22) Near the middle position in the left-right direction, the lower part is tilted rearward and the rug is attached to an endless body with an arbitrary width and length. Provided at the height, the vertical transfer device (1
6) A blower pipe (23) was installed from the blower device (3) provided at the rear part of the blower device to the curver device (2), and the air was blown by the blower device (3) from the tip of the blower pipe (23). Compressed air for the curling device (2)
