While changing the posture so that the inclination angle gradually increases to the inclined posture, the work machine body 2 is moved upward, that is, dumped backward. Further, in the second state, when the rotating body 36 is rotated by the contraction operation of the cylinder 40, the mounting body 31 that has been positioned at the upper limit position in the rearward and downward inclined posture gradually moves from the inclined posture to the horizontal posture. It moves downward relative to the machine frame 3 of the work machine body 2 while changing the posture so that the inclination angle decreases. In addition, the back-and-down tilt posture of the mounting body 31 is a tilted posture in which the mounting surface 30 gradually moves downward from the front end toward the rear end.

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

  When the harvested crop A is stored in a container (a crop container) B which is a storage box on the mounting body 31, the first connection hole portion 46 of the first connection link 32 is mounted as shown in FIG. A first connecting hole 66 of the projecting plate 62 of the body 31 is rotatably connected by a connecting pin 70, and an empty container B is mounted on the mounting body 31 in a horizontal posture.

  When the agricultural machine 1 is moved and moved on the field by driving the crawler 4, the crop A is dug up by the digging blade 14, then conveyed by the digging conveyor 5, and then on the sorting conveyor 6. And is transported horizontally by the sorting conveyor 6.

  The worker sitting on the chair 22 on the side of the sorting conveyor 6 performs the sorting operation, and manually picks up only the crop A to be accommodated from the sorting conveyor 6 and puts it into the container B. Thus, the crop A becomes the container B. Sequentially accommodated. When the container B is filled with the crop A, the empty container B is stacked on the full container B and the harvesting operation is continued.

  Then, when a predetermined number of containers B on the mounting body 31 are full, as shown in FIG. 9, the full containers B are transferred to the truck bed 71. At the time of this replacement, the mounting body 31 is moved up with respect to the machine frame 3 of the work machine body 2 in a horizontal posture by extending the cylinder 40, and the full container B is brought to a desired height position. lift.

  After the replacement, the cylinder 40 is contracted to move the mounting body 31 down to a desired position with respect to the machine frame 3 of the work machine main body 2 while maintaining the horizontal posture, and again on the mounting body 31 in the horizontal posture. The container B is placed and the harvesting operation is continued.

  On the other hand, for example, when the harvested crop A is stored in a flexible container bag (a crop container) that is a storage bag placed in the corner of the field, the second connection hole portion of the first connection link 32 as shown in FIG. 47 is connected to the second connected hole 67 of the protruding plate 62 of the mounting body 31 by a connecting pin 70 so as to be rotatable, and the mounting body 31 is positioned at the lower limit position and set in a horizontal posture.

  Further, for example, a bottom plate 72 such as an iron plate is placed on the placement surface 30 so that the crop A does not fall between adjacent rod-shaped members 60, and the front end that is one end portion of the placement body main body 61 of the placement body 31 A front plate 73 which is a fixed plate for preventing fall is attached to the part, and a rear plate 74 which is a rotation plate for preventing fall is attached to the rear end which is the other end of the mounting body 61. And a stopper 75 for restricting the rotation of the rear plate 74 in a standing posture (see FIG. 11).

  When the agricultural machine 1 is moved and moved on the field by driving the crawler 4, the crop A is dug up by the digging blade 14, then conveyed by the digging conveyor 5, and then on the sorting conveyor 6. And is transported horizontally by the sorting conveyor 6.

  An operator sitting on a chair 22 on the side of the sorting conveyor 6 performs a sorting operation, and picks up only the crop A to be accommodated manually from the sorting conveyor 6 and places it on the bottom plate 72 of the mounting body 31. In this way, the crop A is directly placed on the mounting body 31 sequentially.

  Then, when a predetermined amount of the crop A is accumulated on the mounting body 31, as shown in FIG. 11, the crop A is dropped from the mounting body 31 by its own weight, thereby forming a bottomed cylindrical shape at the corner of the field. The flexible container back C set in the flexible container base D is accommodated.

  That is, after moving the farm work machine 1 to the corner of the farm field, when the cylinder 40 is extended, the mounting body 31 changes its posture from a horizontal posture to a front and rear, lower and lower inclined postures, It moves upward relative to the machine casing 3 of the main body 2.

  Then, in a state where the rear end portion of the mounting body 31 in the rearward and downward inclined posture is positioned above the upper surface opening of the flexible container back C, the restriction by the stopper 75 is released and the rear plate 74 is attached to the mounting body main body 61. When rotated, the crop A rolls down on the mounting body 31 and is accommodated in the flexible container bag C. After accommodating the crop A, the cylinder 40 is contracted to lower the placing body 31 to return to the horizontal posture, and then the harvesting operation is continued.

  For example, although not shown, there are cases where the crop A is stored in a container B placed at the corner of the field, or where the crop A is stacked at the corner of the field.

  As described above, according to the farm work machine 1, it is not necessary to replace the entire mounting body 31 according to the accommodation method, and the rear end portion of the machine frame 3 of the working machine body 2 and the protruding plate 62 of the mounting body 31. By changing the connecting position of the first connecting link 32 that connects the two to the mounting body 31, it is possible to easily cope with different accommodation methods for the crop A. Moreover, the connection between the first connecting hole 46 and the first connected hole 66 and the connection between the second connecting hole 47 and the second connected hole 67 can be easily performed by the connecting pin 70. The connecting position of the first connecting link 32 with respect to the mounting body 31 can be easily changed by inserting and removing the connecting pin 70.

  In addition, the agricultural working machine 1 is not limited to the self-propelled configuration having the crawler 4, and may be, for example, a towed configuration that is connected to a rear portion of a tractor that is a traveling vehicle. The crop A is not limited to potatoes, and may be other than root vegetables.

  For example, although not shown, the first connecting portion and the second connecting portion of the first connecting link 32 are holes, and the first connected portion and the second connected portion of the mounting body 31 are rotated to the holes. The structure which is a shaft part inserted so that it is possible may be sufficient.
