However, in order to open an inspection tool in the combine of patent document 1, before removing the cover body which covers an inspection tool, two outer covers which cover a part of this cover body [third side cover 61 in patent document 1] 2nd side cover 55], and it is necessary to follow several procedures. Moreover, since the inspection opening is formed over the whole of the gas front-back direction in the side wall of a grain tank, the operation | work which removes the cover body and outer cover body which cover this is large scale. Therefore, in the combine of patent document 1, maintenance of the inside of a grain tank was not able to be performed easily.

In view of the above circumstances, a harvesting machine capable of easily opening and closing the inspection opening formed in the grain tank and easily performing maintenance inside the grain tank is desired.

By the way, in the combine of patent document 1, when the cover body contacts the edge part of an inspection tool from the outer side, the said inspection tool is blocked. Therefore, when the pressure which acts toward the outer side of a grain tank becomes high by the grain accumulate | stored in the inside of a grain tank, a pressure acts toward an outer side, ie, the side from which a cover body is peeled off with respect to a cover body. Therefore, in the conventional structure, there exists a possibility that a cover body may fall out by the pressure inside a grain tank, and there existed room for improvement about the durability with respect to the said pressure.

In view of the above situation, there is a demand for a harvester in which the grain opening is provided with an inspection tool that can be used during maintenance, but the inspection opening is not unexpectedly opened due to the pressure inside the grain tank.

In this case, trouble is required for disconnection of the remote control device and the operation cable, and the labor required for taking out the sorting frame increases. Moreover, the take-out method which removes a remote control apparatus and extracts a remote control apparatus with a selection frame may be employ | adopted, with the remote control apparatus and an operation cable connected. In this case, trouble is required for detaching the remote control device, and the labor required for taking out the sorting frame increases.

Therefore, the harvesting machine which can take out a sorting frame quickly is desired.

When the technique disclosed in Patent Document 3 is adopted, the threshing device or the grain tank is located in front of the quick transmission device when shifting the quick transmission device, so that the threshing device or the like becomes an obstacle of the shifting operation. It is difficult to perform the shift operation.

Therefore, the harvesting machine which is easy to shift-operate a quick transmission device is desired.
