Abstract

PURPOSE:To excellently overflow grain in a simple structure and to smoothly discharge it by forming an overflow port to the upper end face of a gutterlike case provided between the basket of a sorting machine and a storage tank and turning the valve plate thereof. CONSTITUTION:A thin type gutterlike case C having a discharge port 12 to the downside part is interposed between the basket A of a sorting machine and a storage tank B. An overflow port 5 constituted of an inclined face 4 is formed to the upper end face of the gutterlike case C. A valve plate 6 is provided to the overflow port 5 freely by a fulcrum shaft 7. While grain supplied from the lower part is lifted between a sorting net cylinder 2 and a lifting rotary cylinder 1 by this rotary cylinder 1, it is introduced into the storage tank B from a discharge port 3 and reaches the vicinity of the downside of the overflow port 5. When the bottom side of the upper face of grain leans on the upper face of the lower part of the valve plate 6 which becomes the oblique lower-position side than the fulcrum shaft 7, the valve plate 6 is turned around the fulcrum shaft 7. In such a way, grain is excellently overflowed from the overflow port 5 and intactly discharged through the inside of the gutterlike case C.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical grain that can be sufficiently filled and overflowed well when the grain selected and lifted by a vertical grain sorter is put into a storage tank. The present invention relates to an overflow device for a sorting machine.

[0002]

2. 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.

[0003]

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.

[0004]

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.

[0005]

Therefore, although the upper surface of the grain discharged from the discharge port into the storage tank rises as a mountain, it rises up to the vicinity of the inclined overflow port where the valve plate is matched and closed. 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a cross-sectional view of the main part of an embodiment of the present invention, in which a vertical sorting spiral 1 is provided inside a vertical sorting machine casing A.
A rotatable selection net cylinder 2 that internally houses a rotatable lifting rotary cylinder 1 having a is erected, and is installed between the lifting rotary cylinder 1 and the selection net cylinder 2 from the lower part of the separator casing A. The grain can be supplied, and the sorting machine casing A is provided on the outer periphery of the upper end of the lifting rotary cylinder 1.
A plurality of discharge blades 10 capable of discharging grains are attached to the discharge port 3 formed on the upper side of the storage tank B having a discharge port 11 at the lower part so that the discharge port 3 communicates with the upper inside. A vertical grain sorter is constructed in the same manner as in the conventional type by connecting to the upper side of the sorter casing A.

A thin trough-shaped case C having a discharge port 12 at a lower side portion between the sorting machine casing A and the storage tank B.
And the discharge port 3 is provided on the upper end surface of the gutter-shaped case C.
From the bottom of the storage tank B toward the upper part inward of the storage tank B, and a sloped surface 4 is formed with a horizontally long quadrangular overflow port 5 having a stopper 8 at its upper edge. 5 is formed on the upper edge of a horizontally long quadrangular valve plate 6 that can come into contact with the upper side of the stopper 8 and a bent edge 66 is formed on the lower side of the lower edge side. A lateral fulcrum shaft 7 is fixed to the lower surface which is the longitudinal intermediate portion of the fulcrum shaft. Metal 13 provided on the bottom surface of 4,
A tension spring type ammunition 9 for pressurizing the valve plate 6 in a closing direction is connected to the lower surface of the upper portion of the valve plate 6 which is rotatably pivoted to each of 13 and is located above the fulcrum shaft 7. However, a weight that can pressurize the valve plate 6 in the closing direction may be attached to the valve plate 6.

Therefore, while the grains supplied from the lower part are lifted by the lifting rotary cylinder 1 between the screening net cylinder 2 and the lifting rotary cylinder 1, small grains and dust are removed from the screening net cylinder 2. 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.

[0009]

As described above, according to the present invention, in the state where the grains fed into the storage tank B from the discharge port 3 are piled up, the piles are formed near the lower portion of the overflow port 5 closed by the valve plate 6. Grain can be sufficiently stored in the storage tank B until the bottom side of the upper surface of the grain is stretched to a certain extent, and the grain can be sufficiently stored even if the storage tank B is not upsized. When the grain is thrown in and the grain rests on the upper surface of the lower portion of the valve plate 6, the valve plate 6 automatically stands up and opens while rotating around the fulcrum shaft 7, and the grain becomes the valve plate 6. While it is being guided, it overflows satisfactorily and is discharged from the gutter-shaped case C, so that the overflow performance can be further improved also from the storage tank B. Further, the gutter-shaped case C has the gutter-shaped case C. A and storage tank It can be mounted and mounted easily between the and, and the inside of the sorting machine casing A can have a compact structure with good sorting performance. Have.
