The culm supply device 5 takes over, and the grain culm supply device 5 supplies the culm to the threshing device 3 to thresh. In this case, when the reaper 10 is moved to the left or right with respect to the machine depending on where the machine is traveling, it is efficient because there is no uncut residue, and the reaper frame 20 of the reaper 10 is fixed to the left and right with respect to the machine. Since the fixed frame 21 and the moving frame 22 are formed, the moving frame 22 is moved with respect to the fixed frame 21.

That is, when the reaping movement motor 39 is operated, the fixed-side rotation horizontal shaft 38 rotates via the rotation transmission member 40, and the spiral groove 44 on the outer periphery of the fixed-side rotation horizontal shaft 38 protrudes from the movement member 43. 45, the moving member 43 is moved left and right with respect to the fixed-side rotating horizontal shaft 38, and when the moving member 43 moves, the sliding member 42 to which the moving member 43 is attached is attached.
Move left and right, and the moving frame 22 moves the moving member 43.

When the handling depth adjusting motor 32 is operated, the link mechanism 31 rotates the rotating arm 30, the rotating arm 30 pushes the engaging rod 28, and the engaging rod 28 moves the transmission case 27. When the rotation arm 30 is rotated with respect to the vertical transmission box 25 to move the starting end of the stock transfer side transfer device 18 upward, and conversely, when the rotating arm 30 is rotated in a direction away from the engagement rod 28, the stock side transfer is performed. The starting end is moved downward due to the weight of the transfer device 18. Therefore, as the tip of the stocker side transfer device 18 moves up and down, the grain culm holding position is changed to adjust the handling depth. In this case, when the starting end of the stock transfer side transfer device 18 moves up and down, the rotating arm 66 and the rotating arm 68 rotate accordingly and the top and bottom of the tip of the transfer stock side transfer device 18 are not obstructed.

In the second embodiment shown in FIGS. 12 to 14, the protrusion 87 engaged with the spiral groove 44 of the fixed side rotating horizontal shaft 38 is

Therefore, since the insertion member 86 moves separately from the moving member 43, the work is facilitated during maintenance or position adjustment. Further, the lateral movement of the insertion member 86 is guided by the contact member 85 having a half-moon shape in cross section, which is in sliding contact with the fixed lateral support shaft 36, so that the lateral movement is surely and smoothly performed. Further, since the guide arm 89 is rotatable with respect to the arm 88 and the arm 88 is rotatable with respect to the fitting / inserting member 86, the handling depth adjusting motor 32, the link mechanism 31,
When the transmission case 27 is rotated with respect to the vertical transmission box 25 via the rotating arm 30 and the engagement rod 28 to vertically move the starting end portion of the stocker side transfer device 18, there is no obstacle. In the third embodiment of FIGS. 15 to 17, the moving member 43 is moved with respect to the fixed-side rotating horizontal shaft 38 via the cutting movement motor 39, the fixed-side rotating horizontal shaft 38, the spiral groove 44, and the projection 45 of the moving member 43. When is moved to the left or right, the arm 92 and the guide arm 93 are laterally moved by the movement of the moving member 43, and the starting end portion of the stocker side transfer device 18 is moved in correspondence with the horizontal movement of the moving frame 22. In this case, the raising device 12
The guide mechanism 6 is attached to the moving member 43 that can be detachably attached to the sliding member 42, not to the rear side horizontal moving frame 47 provided with the above.
Since 4 is provided, mounting is easy. Also, the arm 92
Is rotatable with respect to the horizontal shaft 91, and the guide arm 93 is rotatable with respect to the arm 92. Therefore, when the starting end portion of the stocker side transfer device 18 is moved up and down, The arm 92 rotates and does not become an obstacle. In the fourth embodiment of FIGS. 18 to 22, when the moving member 43 moves, the guide engaging rod 97 moves, and the guide engaging rod 97 is inserted into the engaging hole 94 of the frame 82 of the stocker side transfer device 18. Since they are engaged, the starting end of the stock transfer side transfer device 18 is moved in correspondence with the horizontal movement of the moving frame 22. Further, since the guide engagement rod 97 is formed in an arc shape in accordance with the locus of the stock source side take-over transfer device 18 rotating around the transmission case 27, the stock base side take-over transfer device 18 is adjusted by adjusting the handling depth. It does not become an obstacle when the starting end of is moved up and down.
