During the insertion, the stopper 97 is pushed by the string-like portion 17b and slightly elastically deformed. However, when the string-like portion 17b is separated from the stopper 97, the stopper 97 returns to the original state based on the elastic restoring force.

  Next, the operation of the harvester 1 will be described.

  When the harvester 1 travels forward on the field by driving the crawler 3, the crop A connected by the stem B is dug up by the digging blade 11, and then the transport body 22 and the scraper of the first transport means 6. The harvesting means 14 is harvested from the field and transported. In the middle of this conveyance, foreign matters such as soil and pebbles fall from the gap 21 between the rods 27 onto the field.

  Then, the crop A connected by the stem B comes into contact with the presser body 52 of the stem separation means 7 in the vicinity of the end of the transport of the first transport means 6, and while being pressed by the presser body 52, the side of the drive roller body 51 Guided towards

  Then, the stem B is separated from the crop A by being pinched and pulled by the rod 27 at the conveyance end of the conveyance body 22 that is driven to rotate and the roller member 58 of the drive roller body 51 that is driven and rotated. . The stem B extracted from the crop A in this manner falls on the field. At this time, in addition to the stem part B, the root part of the crop A and the miscellaneous matters such as grass that have been transported together with the crop A are sandwiched between the transport terminal part of the transport body 22 and the drive roller body 51 and separated. Fall on the field.

  Then, when the stem B is separated from the crop A, the crops A are separated one by one and temporarily stay on the cushion plate 84 on the stay plate 81.

  Subsequently, the separated crop A is transported and lifted by the transport body 41 of the second transport means 8, then transferred to the third transport means 16 and horizontally transported by the third transport means 16. On the third transport means 16, it is sorted by the worker who has got on the work step 19. For example, the damaged unnecessary crop A, dirt, stones, and other miscellaneous matters are returned to the field, and the other crops A are carried out from the transfer end portion of the third transfer means 16.

  Then, the crop A carried out from the conveyance end portion of the third conveyance means 16 of the conveyance means 20 falls, passes through the upper surface opening 17a, and is accommodated in the bag body portion 17c. That is, the crop A is placed on the mounting table 18 and is dropped and accommodated in the accommodation bag 17 in which the upper surface opening 17a is maintained in the open state by the bag support 91.

  When the inside of the containing bag 17 is filled with the crop A, the string-like part 17b is taken out of the insertion space part 98 by pulling the string-like part 17b outward and slightly elastically deforming the stopper 97 upward, The support of the storage bag 17 by the bag support 91 is released.

  Thereafter, the full storage bag 17 is lowered from the mounting table 18, and the empty storage bag 17 is mounted on the mounting table 18. Then, the string-like portion 17b of the empty storage bag 17 is pushed into the gap 111 from the outside and the stopper 97 is slightly elastically deformed upward, thereby inserting the string-like portion 17b into the insertion space portion 98 and supporting the bag. The housing bag 17 is supported by the body 91, and as a result, the upper surface opening portion 17a of the housing bag 17 is maintained in an open state opened upward.

  And according to such a harvester 1, the string-like part 17b of the storage bag 17 is supported by inserting the string-like part 17b of the storage bag 17 into the insertion space part 98 by elastically deforming the stopper 97. The strap 96 can be easily hooked to the shaft 96, and the string-like portion 17b of the storage bag 17 hooked to the support shaft 96 is restricted from moving to the tip side of the support shaft 96 by contact with the stopper 97. It is possible to prevent the hooked string portion 17b from being inadvertently detached from the support shaft 96.

  Further, the gap 111 communicating with the insertion space portion 98 is provided between the curved surface 110 and the support shaft 96 in a state before the stopper 97 is elastically deformed so that the string-like portion 17b is inserted into and removed from the insertion space portion 98. Therefore, the string-like portion 17b of the storage bag 17 can be more easily hooked by inserting the string-like portion 17b of the storage bag 17 into the insertion space portion 98 so as to be pushed from the gap 111.

  Furthermore, the stopper 97 can be easily attached to the support shaft 96 only by screwing the bolt 104 into the screw hole portion 102 of the support shaft 96.

  Further, the stem B is separated from the crop A by the stem separating means 7 having the driving roller body 51 and the presser body 52 and falls to the field, and the separated and removed stem B is separated by the second transport means 8. Since it is not transported, it is not necessary for the operator to manually select the crop A and the stem B and remove the stem B, and the harvesting operation can be performed efficiently.

  Further, since the distance between the driving roller body 51 and the conveyance end portion of the conveyance body 22 of the first conveyance means 6 can be adjusted by operating the adjustment bolt 55, for example, the stem B having a different thickness or the like Can respond appropriately.

  In addition, an annular groove 59 that allows the sprocket 32 to pass through is formed in a portion of the outer peripheral portion of the drive roller body 51 that faces the sprocket 32 of the drive rotator 24, so that the drive roller body 51 and the sprocket 32 Interference can be prevented.

  Further, the presser body 52 is disposed so as to be vertically rotatable so that the rear end part moves up and down around the front end part, and the stem part separating means 7 moves the presser body 52 downward at the rear end part of the presser body 52. Since the coil spring 71 is energized in such a direction, the crop A connected by the stem B can be appropriately guided toward the drive roller body 51 regardless of the size of the crop A or the like.

  Further, since the staying plate 81 is provided between the drive roller body 51 and the transport start end portion of the second transport means 8 and retains the crop A, the drive roller body 51 and the transport body 22 of the first transport means 6 are provided. The stem B can be sandwiched between the end of the conveyance and can be appropriately separated from the crop A.

  The harvesting machine 1 is not limited to a self-propelled configuration having the crawler 3, but may be a towed configuration that is connected to the rear portion of a tractor that is a traveling vehicle, for example.

  Further, the crop A is not limited to sweet potatoes, but may be potatoes or the like.

Further, even before the stopper 97 is elastically deformed, there is no gap between the curved surface 110 and the support shaft 96, and the curved surface 110 is in contact with the upper surface of the tip end portion of the support shaft 96 so as to be able to contact and separate. Good .
