In addition, by adjusting the vertical position of the support 42 with respect to the rotating body 36 (vertical slide adjustment), it is possible to simultaneously change the interval a between the lower ends of the two reverse guide bars 31 among the multiple reverse guide bars 31 ( Adjustable). As the distance a between the two reversing guide bars 31 is changed, the size of the guide surface 50 formed by a plurality of the reversing guide bars 31 that is inclined forward and downward is also changed.

  That is, for example, in the state shown in FIG. 7, the inclination angle α of the reversing guide bar 31 is 80 °, and the distance a between the lower ends of both reversing guide bars 31 adjacent to each other is 66 mm. In the state shown in FIG. 8, the inclination angle α of the reversing guide bar 31 is 80 °, and the distance a between the lower ends of both reversing guide bars 31 adjacent to each other is 60 mm.

  In the state shown in FIG. 9, the inclination angle α of the reversing guide bar 31 is 60 °, and the distance a between the lower ends of both reversing guide bars 31 adjacent to each other is 66 mm. In the state shown in FIG. 10, the inclination angle α of the reversing guide bar 31 is 60 °, and the distance a between the lower ends of both reversing guide bars 31 adjacent to each other is 60 mm.

  Note that the inclination angle α and the interval a can be set to values other than those shown in FIGS. 7 to 10, and the operator sets the values according to the state of peanut A prosperity.

  Next, the operation and the like of the farm work machine 1 will be described.

  When the agricultural machine 1 is moved forward by the traveling of the tractor while the agricultural machine 1 is connected to the tractor, the peanut A vegetated on the straw of the field is first cut by the root cutting means 3. Then, the root side part A2 in the soil is dug up on the ground.

  At this time, the root cutting means 3 cuts the root of the root side portion A2 of the peanut A with the digging blade 17 while oscillating, while pushing the stalk and leaf portion A1 of the peanut A forward by the posture control roller 18. From a normal posture (vegetation posture) in which the foliage portion A1 is located on the upper side, a forward leaning posture is assumed in which the foliage portion A1 is located on the front side.

  Then, the peanut A after cutting the root in the forward tilted posture is supplied onto the transport body 21 of the transport means 4 while being in the forward tilted posture, and is transported obliquely upward and rearward by the transport body 21.

  After that, when the peanut A in the forward tilted position is unloaded from the transport end portion of the transport body 21, it is discharged backward in the forward tilted position by the discharge roller 26, and a plurality of the position change means 6 are reversed. Collides with guide bar 31.

  Then, the peanut A changes its posture from the forward leaning posture to the reverse posture based on the momentum of collision with the reverse guide rod 31 and the inclination angle α of the reverse guide rod 31.

  Then, the peanut A in the inverted posture slides down on the forward and downward inclined guide surface 50 composed of a plurality of the inverted guide rods 31 in the inverted posture toward the center in the left-right direction of the guide surface 50, It falls from the drop opening 35 onto the field fence.

  In this way, for example, the two strips of peanuts A vegetated in the field are placed in a row substantially in the front-rear direction in an inverted posture on the ridges of the field (see FIG. 2). In addition, the peanut A placed on the field is harvested after being naturally dried by ground drying or the like.

  And according to the said farming machine 1, since the attitude | position change means 6 has the several inversion guide stick | rod 31 which can adjust the inclination | tilt angle (alpha) with respect to a horizontal direction, the prosperous state of the foliage part A1 changes with growth conditions etc., for example. The peanut A can be handled, and the peanut A can be appropriately reversed by the posture changing means 6 regardless of the peanut A's prosperous state, so that the efficiency of the harvesting work can be improved.

  Further, by adjusting the position of the support 42 with respect to the rotating body 36 of the posture changing means 6, the distance a between the adjacent reverse guide bars 31 and the size of the guide surface 50 including the multiple reverse guide bars 31 can be changed. Therefore, the peanut A can be reversed more appropriately, and the efficiency of the harvesting work can be effectively achieved.

  Note that the posture changing means 6 is not limited to the one having the reversing guide rod 31, the rotating body 36, and the supporting body 42. For example, the upper end of the reversing guide rod rotates to the rod mounting portion of the machine body. The structure etc. which were attached possible may be sufficient.

  Further, the tilt angle α of the plurality of reversing guide bars 31 is not limited to a configuration that can be adjusted all at once. For example, the tilt angles of the reversing guide bars may be adjusted by a predetermined number, not all at once. .

  Further, the configuration is not limited to the configuration in which the operator manually rotates the rotating body 36 to adjust the inclination angle α of the reversing guide rod 31. For example, the rotating driving means for rotating the rotating body with respect to the machine body is provided. Further, a configuration in which the tilting angle of the reversing guide rod is adjusted by rotating the rotating body with the driving force of the rotation driving means may be used.
