Description of the Related Art Conventionally, a reservoir connected to a discharge port on the upper side of the sorting machine casing has an upper side portion of an upright sorting machine casing containing a lifting rotary cylinder and a sorting mesh cylinder on the outer periphery thereof. A vertical grain sorter constructed by connecting tanks in series
As seen in Japanese Patent Laid-Open No. 42-42, the grain in the storage tank can be overflowed from an overflow port formed on the outer peripheral wall of the sorting machine casing on the lower side of the discharge port and discharged through a gutter provided in the sorting machine casing. It was like this.

ければならなくなる、といった不具合を呈していた。However, in such a structure, since the overflow port stands upright below the discharge port, the upper surface of the grain put into the storage tank rises to the site of the overflow port. If it does, it will immediately flow in and overflow, and it will not be possible to store enough grains in the storage tank, increasing the size will increase the cost, and also install a gutter in the casing of the sorter. Therefore, there is a problem that the sorting body in the sorting machine casing is regulated and the sorting performance cannot be improved, and moreover, the sorting machine casing has to be upsized.

ある。The present invention has been devised so as to solve such a problem and to allow good overflow. Therefore, a thin type housing is provided between the selector casing and the storage tank. A trough-shaped case is interposed, and an overflow port is formed on an inclined surface that is an upper end surface of the trough-shaped case, and the valve plate is in an upright state at an intermediate portion on both end sides of the valve plate that matches the overflow port. It is configured to be pivotally supported on a fulcrum shaft so that it can be rotated and opened.Also, a portion above the fulcrum shaft of the valve plate is brought into contact with a lower stopper to close it, or in a direction to close the valve plate. It is constructed by attaching a pressurizing bullet or weight to the valve plate.

Grains can be sufficiently stored in the storage tank until the bottom side of the upper surface of the grain rests, and further, the bottom side of the valve plate where the bottom side of the upper surface of the grain is tilted lower than the fulcrum axis is added When it hangs on the upper surface, the valve plate automatically stands up and opens while rotating around the fulcrum axis, and the grains satisfactorily overflow as it is guided by the valve plate. Will be discharged smoothly.

When the selected grain is lifted, the sorted grain is lifted, and is fed into the storage tank B from the discharge port 3 by each discharge blade 10, and the upper surface of the grain becomes a mountain. As shown in FIGS. 1 to 4, the storage tank B continues to rise until the bottom side of the upper surface of the grain rests near the lower side of the overflow port 5 where the valve plate 6 is closed as shown in FIGS.
The grain can be sufficiently stored in the inside, and the grain is further charged, and the bottom side of the upper side of the grain is inclined downward from the fulcrum shaft 7 and leans on the lower upper face of the valve plate 6 as shown by the arrow a. Then, the valve plate 6 automatically stands up and opens while rotating around the fulcrum shaft 7 as shown in FIG. 5, and the grain is guided by the valve plate 6 from the overflow port 5. It overflows satisfactorily and is discharged smoothly through the trough-shaped case C as it is, and when it does not overflow, the valve plate 6 is automatically closed.
