Next, the operation and the like of the harvester 11 described above will be described.

When the harvester 11 is moved forward (in the direction of travel shown in FIG. 1) so that the left and right gauge wheels 24 run on the hem of the ridge by the operation of the crawler 14 in the field, the harvested product W in the soil of the ridge in the field W. Is dug out of the soil of the ridge by the excavation blade 23 of the front side portion 15a of the conveyor, and the excavated harvest W is collected by the transport portion 16 located over the front side portion 15a of the conveyor and the rear portion 15b of the conveyor. The conveyor is transported in the transport direction, and is manually picked up from the transport unit 16 by a worker sitting on the seat 26 during the transport and stored in the container.

At this time, the harvested product W placed on the transport section 16 of the conveyor 15 is prevented from rolling in the opposite direction direction due to the contact with the rising conveyor bar 43a, so that the transport section 16 appropriately prevents the harvested product W from rolling in the transport direction. Be transported.

Here, for example, as shown in FIG. 8A, even if foreign matter (for example, pebbles K) enters between the rising conveyor bar 43a and the side plate 46b of the rear side portion 15b of the conveyor, the long portion of the core member 131. The longitudinal end 134 of 133 is entirely covered with the rubber covering member 132, and the thickness of the rubber covering member 132 covering the entire end surface 134a of the longitudinal end 134 of the elongated portion 133 is Since it is sufficiently thick, the rubber covering member 132 does not peel off from the end portion 134, and the durability of the rising conveyor bar 43a is improved.

Further, for example, after the work is completed, as shown in FIGS. 3 and 4C, the front side portion 15a of the conveyor is rotated upward by the cylinder 21 to put it in a non-working state, and then the attachment / detachment pin 77 is fixed in the hole for fixing. The safety cover member 76 is fixed to the side plate 46b of the rear side portion 15b of the conveyor by inserting it into 79, 91, 92 and inserting the R pin 93 into the tip side hole 83 of the attachment / detachment pin 77. This makes it possible to regulate (prevent) the downward rotation of the conveyor front portion 15a in the non-working state by using the safety body 71. Further, the small and lightweight harvester 11 in the state shown in FIG. 3 can be mounted on the loading platform of a light truck, which is a small cargo vehicle.

Then, according to such a harvester 11, the entire longitudinal end 134 of the elongated portion 133 of the core member 131 of the rising conveyor bar 43a is wrapped around the entire circumference by the rubber covering member 132. Since it is firmly covered, it is possible to appropriately prevent (suppress) the rubber coating member 132 from peeling off from the longitudinal end 134 of the long portion 133. Therefore, the durability of the rising conveyor bar 43a can be improved, and the harvesting work can be performed appropriately without damaging the harvested material with the core material from which the rubber coating has been peeled off, for example.

Further, since the notch portion 143 is formed in the mounting portion 136 of the core member 131 of the rising conveyor bar 43a, the rubber covering member 132 easily and appropriately covers the entire longitudinal end portion 134 of the long portion 133. can.

Further, since the longitudinal end 134 of the elongated portion 133 is located inside the end surface 137a of the outer end portion 137 of the mounting plate portion 141 of the mounting portion 136, the entire end surface 134a of the end portion 134 is covered. The thickness of the rubber covering member 132 to be covered can be made sufficiently thick, and the durability can be further improved.

On the other hand, even if the non-working state (retracted state) conveyor front side portion 15a tries to rotate downward with respect to the conveyor rear side portion 15b due to its own weight due to a failure of the cylinder 21, the non-working state conveyor front side portion 15a Since downward rotation (fall due to its own weight) is regulated by the safety body 71 in a fixed state, a fall prevention member separate from the safety body 71 is not required, and the number of parts can be reduced accordingly. It is possible to reduce the weight and cost.

Further, by replacing the attachment / detachment pin 77 from the work hole 78 to the fixing holes 79, 91, 92, the safety cover member 76 can be easily and surely fixed to the rear side portion 15b of the conveyor, and the operator can attach / detach it. By replacing the pin 77, it is possible to confirm (consciously) fix the safety cover member 76 and prevent forgetting to fix it.

Further, the detachable pin 77 slides in a state where the lower end thereof is in linear contact with the upper surface 87a of the upper plate portion 87 of the side plate 46 (46b) of the rear side portion 15b of the conveyor. It can slide smoothly with less frictional resistance than the structure that slides. For example, the detachable pin 77 may move on the upper surface 87a while rotating.

In the above embodiment, the configuration in which the mounting portion of the main body of the transport member is welded and fixed to the long portion has been described, but for example, the mounting portion may be integrally projected from the long portion.

Further, the long portion of the main body of the transport member is not limited to the round shaft shape, and may be, for example, a square shaft shape or a shape other than the shaft shape.

Further, although the transport member such as the rising conveyor bar is suitable for the harvester transport means of the harvester, it can also be applied to other transport means for transporting the object to be transported.
