Embroidery star foil 39, taking over the culm after scraping, changing the posture to the side-down posture while transporting it backwards, and
It is composed of a transfer device 40 to be delivered to the dochien 34 and the like. The reaping section 33 moves the reaping main frame 4 to the body.
1 and is connected so as to be able to ascend and descend around a horizontal axis X, and is configured to be able to be vertically driven by a hydraulic cylinder -42. In addition, the harvested grain culm transport device 40 is configured such that the starting end side swings in the left-right direction with the longitudinal axis Y provided at the end side as a fulcrum. A horizontal input shaft 43 is arranged in the same axis as the horizontal axis X, and power is transmitted from the prime mover via an input pulley 44 attached to one end of the input shaft 43. The lateral drive shaft 46 is rotatably driven from the other end of the input shaft 43 via a gear mechanism 45, and the transport device is transported via a transport drive shaft 47 and a vertical drive sprocket which are coaxial with the vertical axis Y. The forehead transport chain 40a and the stock-source transport chain 40b are interlocked to be driven. Further, the grain culm conveying device 40 is configured to be supported so as to be able to move up and down with the horizontal transmission shaft 46 as a fulcrum so that the handling depth can be adjusted, and to be pivotally attached to the machine side. Arm 49 that moves up and down around the supported shaft 48
Is supported via a roller 50, and a mowing transmission case described later is provided.
The starting end moves in the left-right direction with the movement of the moving frame 54 which also serves as the motor 53 (this moves around the vertical axis Y on the end side).
It has a configuration that can be used. The starting end of the transporting device 40 is configured to be movable in an oblique direction so as to be displaced to the front side with a lateral movement from a right side S1 position to a left side S2 position beyond a front-rear direction line A passing through the vertical axis Y. ing. Therefore, even if the starting end of the transport device swings right and left about the vertical axis Y as the rotation center, the relative position with respect to the forward cutting pre-processing unit does not change significantly, and the substantially constant relative position is maintained. become. A front-rear transmission shaft 55 projecting forward from an intermediate portion of the lateral input shaft 43 via a bevel gear mechanism 55a, and a front-rear transmission shaft 56 projecting rearward from the cutting transmission case 53. Are connected to each other by a retractable and refractable cutting power transmission shaft 57. In other words, the mowing transmission shaft 57 can slide and expand and contract with each other, and is interlockingly connected between the transmission shafts 55 and 56 via the universal joints 58 and 59. The moving frame 54 is integrally framed by a guide rail member 60 disposed obliquely in the lateral direction and a weed supporting rod 62 having a weed body 61 at the tip. A guide rail member 60 provided on the front side of the moving frame 54 is slidably mounted on a guide roller 63 provided on the leading end of the cutting main frame 41 so as to slide left and right. A sliding ring 64 provided on the rear side is fitted to a support pipe 65 provided to be supported in a laterally oblique direction at an intermediate portion on the side of the cutting main frame 41 so as to be slidable left and right. The mowing main frame 41 has an electric motor 6
A helical shaft 67 driven forward and reverse by 6 is provided. Then, the top member 68 of the moving frame 54 is screwed onto the spiral shaft 67, and the moving frame 5 is rotated by forward and reverse rotation of the spiral shaft 67.
4 is configured to reciprocate horizontally and horizontally. In short, by configuring the transport device so that the forward / backward moving amount L1 of the transport starting end portion and the forward / backward moving amount L2 of the pre-cutting processing unit are substantially the same, the position of the transport starting end portion and the pre-cutting processing unit is reduced. The relationship is maintained substantially constant, so that the transfer between them can be carried out neatly and satisfactorily even at an arbitrary slide position. The raising / lowering arm 49 is pivotally mounted on the vertical axis around the axis Q so as to be swingable in the left-right direction, thereby enabling the transfer device 40 to swing in the left-right direction. The lifting arm 49 is driven up and down via a motor 69, a crank 70, and a crank rod 71, and the handling depth is controlled by the vertical movement of the transfer device 40. Since the raising / lowering arm 49 is supported not by the mowing part but by the machine side, even if the mowing height is changed by raising and lowering the mowing part, the handling depth does not change and the predetermined position is maintained. ing.
