For example, the mounting lifting bolt 32d equipped with a fixed plate 32c made of a rubber material, a resin material or the like is inserted into the support boss 32a and is prevented from coming off by a nut 32e or the like.

  A torque spring 32f is provided on the front support pin 29b between the first position lever 29a and the intermediate support 31c. Due to the action of the torque spring 32f, the fixing plate 32c of the fixture 32 is pressed against the outer peripheral portion of the fixing transfer cylinder 16, and the moving transfer cylinder 17 can be reliably fixed to an arbitrary position in the longitudinal direction.

  The outer diameter of the spiral plate 6m of the tank transfer spiral 6f pivotally supported on the grain storage tank 6, the rear support metal 6d, and the rotating metal 8b is as shown in FIG. The rear support metal 6d and the rotating metal 8b are formed to have a small outer diameter (D1) and a predetermined outer diameter (D2). Furthermore, the transfer bottom portion (b) to which the grains of the rear support metal 6d and the rotating metal 8a are transferred has a wider space than the transfer bottom portion (c) of the grain storage tank 6.

  As a result, the stored grains in the grain storage tank 6 have a large outer diameter (D2) at the outer diameter portion of the spiral plate 6m at the transfer end portion of the horizontal transfer that changes from the horizontal transfer to the vertical transfer. Since the space portion is widened, the transfer resistance of the grain is reduced, and the clogging of the grain and the occurrence of defluxing can be prevented.

  As shown in FIG. 25, a lock device 34f is provided on the other side of the upper / lower transfer cylinders 34a, 34b (the side opposite to the folding tool 34c). Further, even when the folding tool 34c is operated to the maximum extension state, the folding tool 34c is provided so as not to exceed the fulcrum. Further, even when the folding tool 34c is operated to the shortest state and the maximum stretched state, the folding tool 34c is more than the outer diameter portion of the lower transfer cylinder 34b of the side-view grain transfer / discharge cylinder device 34. It is the structure provided in the state which does not protrude.

  When the upper transfer cylinder 34a is operated in a folded state, as shown in FIG. 27, the upper transfer cylinder 34a is stopped in a state where it is tilted upward from the horizontal state by a predetermined angle (α2), thereby preventing grain spillage.

  Thus, the grain transfer / discharge cylinder device 34 can be folded lightly. The total length can be increased. The operability is improved by applying force by exceeding the fulcrum. Grain spillage can be prevented by tilting the discharge cylinder 18 upward from the horizontal. By providing the locking device 34f, the locking can be surely performed. Since the longest of the folding tool 34c is the position beyond the fulcrum, a feeling is good because no force is applied to the folding. Handleability is improved. It is possible to prevent grain spillage.

  The clutch wire 35a provided to the clutch lever 35 provided in the grain transfer / discharge cylinder device 8 has a configuration in which a wire guide 35b is provided at the tip as shown in FIG. Further, the clutch wire 35a is housed in the rear side surface of the grain storage tank 6.

Thereby, the handling of the clutch wire 35a is improved. Also, it won't get in the way.
