In addition, since the outflow of the grains when the grains are discharged by turning the bag upside down is smoothly performed in a state in which the bridge is suppressed, the worker does not have to perform the work of shaking each time, There is also an advantage that workability can be improved.

(Structure) A grain collecting bag for a harvester according to a second aspect of the present invention is the grain collecting bag for a harvester according to the first aspect, wherein a middle portion of a lateral side edge of the bag is sewn inward and constricted. There is a characteristic configuration.

(Operation) According to the configuration of the second aspect of the present invention, since the middle portion of the lateral side edge of the bag is sewn inward and constricted, a hand is required for the constricted portion during manual operation. Can be hung.

(Effect) Therefore, according to the configuration of the second aspect of the present invention, when the bag is held, the constricted portion is manually held as compared with the case where the edge portion is simply linear. This makes it easier to handle.

(Structure) A grain collecting bag for a harvester according to a third aspect of the present invention is the grain collecting bag for a harvester according to the second aspect, wherein holes are formed in both lateral sides on the lower side of the bag so that fingers can be inserted. Is provided as a characteristic configuration.

(Operation) According to the configuration of the third aspect of the present invention, holes are provided on both lower side portions of the bag so that fingers can be inserted into the bag. In the case of supplying to the dryer, the operator can easily turn the bag upside down by holding his / her finger in the hole at the lower end of the bag and repeating the bag.

(Effects) Therefore, according to the configuration of claim 3 of the present invention, when performing an operation of repeatedly flipping the bag, fingers and various instruments are locked in the holes on the lower side of the bag. The operation can be performed very easily by repeating the operation and the workability can be improved.
