The present invention has a function of dropping the harvested bean poles to dry on the ground behind the harvester in the direction of movement, and
In a harvesting machine that has two functions: storing it in a storage container directly connected to the rear of the harvesting machine, one wide conveyor belt 2 is formed, and a plurality of bean rod locking protrusions 3 are provided on its surface. There is no need for a complicated and expensive structure such as arranging book conveyor belts in parallel and requiring a bottom plate in the space between them to prevent the beans from falling. Since it is spread and conveyed on the wide conveyor belt, when it is dropped to dry on the ground, it is spread almost uniformly on the ground, and when it is stored in the storage basket, it is distributed almost uniformly over the entire surface of the basket, and it is scattered evenly on the entire surface of the basket. We never get together.

In addition, the conveyor belt is suspended endlessly, and V grooves are provided on the upper and lower turning shafts 4, 5 and the intermediate drive shaft 6, and the V-shaped protrusions 8 on the inner surface of the conveyor belt are fitted to form a V-belt transmission mechanism. By directly connecting the hydraulic motor to the intermediate drive shaft 6, the drive mechanism for the conveyor band 2 can be made simple and compact, and the conveyor band drive mechanism of this type of harvester, which is often exposed to dust, water, etc. It is extremely effective and suitable as a device. Also conveyor belt 2
Since it is configured to be bent or extended with the intermediate drive shaft 6 as a fulcrum, the action of the V-belt transmission mechanism is ensured in either case.

In addition, since the bean rods are conveyed while being caught on the protrusions 3 on the surface of the conveyor belt, when they are turned from the upper turning shaft 4 to the lower surface of the conveyor belt, they are caught and tend to fall downward.
The scraping rod 22 removes all of the scraping material so that it can be smoothly removed from the conveyor belt. Furthermore, when the conveyor belt is folded in the middle, the bearing ring 21 prevents the conveyor belt located on the lower surface from sagging.
