JPH04334575A - Overflow device of upright cereal grain selection device - Google Patents

Abstract

PURPOSE:To ensure that an adequate amount of cereal grains can be fully loaded from a discharge aperture on the top of an upright cereal grain selection machine into a storage tank and is allowed to overflow satisfactorily in a full capacity state. CONSTITUTION:A thin aqueduct-type case C is present between a selector enclosure A and a storage tank B and an inclined surface 4 with an overflow aperture 5 is formed on the upper end of the case C. In addition, a weight 6 or a valve 7 which presses elastically against an overflow aperture 5 side is installed below the overflow aperture 5 in such a manner that the weight or the valve becomes closed freely.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is directed to a vertical shell grain sorter that allows the shell grains sorted and lifted by a vertical shell grain separator to be sufficiently filled and overflow when being put into a storage tank. The present invention relates to an overflow device for a sorting machine.

0002

[Prior Art] Conventionally, in the upper side of a vertical sorting machine housing containing a lifting rotary cylinder and a sorting net cylinder rod on its outer periphery, there was a storage tank that communicated with a discharge port on the upper side of the sorting machine housing. In a vertical shell grain separator configured with a series of tanks,
As seen in Publication No. 42, shell grains in the storage tank can overflow from an overflow port formed on the outer peripheral wall of the sorter case, which is below the discharge port, and can be discharged through a gutter provided inside the sorter case. It was like that.

0003

[Problem to be Solved by the Invention] However, in such a structure, since the overflow port stands vertically below the discharge port, the upper surface of the shell grains introduced into the storage tank rises to the area of the overflow port. If this happens, it will immediately flow in and overflow, making it impossible to store enough shell grain in the storage tank.If the tank is made larger, the cost will increase, and a gutter will be installed inside the sorting machine housing. Therefore, the sorting bodies inside the sorting machine housing are subject to regulations, making it impossible to improve the sorting performance, and moreover, the sorting machine housing has to be made larger.

0004

[Means for Solving the Problems] The present invention has been devised to solve such problems and to have a simple structure so that it can be carried out suitably. A thin gutter-like case is interposed, and the upper end surface of the gutter-like case is formed with an inclined surface having an overflow port, and below the overflow port is a valve that is pressed toward the overflow port by a weight or an elastic device. It is constructed by attaching the body so that it can be opened and closed.

[0005]

[Operation] Therefore, the upper surface of the granules discharged from the discharge port into the storage tank rises in the form of a mountain. The storage tank will be able to store enough shell grains until the shell grains are piled up to a certain extent, and as more shell grains are added, the hem of the top surface of the shell grains that forms a mountain rises and the shell grains are placed heavily on the slope. Then, while the valve body is automatically opened against the pressure, the shell grains overflow from the overflow port and are smoothly discharged through the gutter-like case outside the sorter housing.

[0006]

[Embodiment] Fig. 1 shows a sectional view of the main part of an embodiment of the present invention.
A rotatable sorting screen tube 2 which houses a rotatable lifting rotary tube 1 having a diameter of 1.a is installed vertically, and a rotatable sorting screen tube 2 is installed between the lifting rotary tube 1 and the sorting screen tube 2 from the lower part of the sorting machine casing A. A sorting machine casing A is provided on the outer periphery of the upper end of the lifting rotary cylinder 1 so that shell grains can be supplied.
A plurality of discharge vanes 8 capable of discharging shell grains are attached to a discharge port 3 formed on the upper side, and the discharge port 3 communicates with the inside of the upper part to form a storage tank B having a discharge port 9 in the lower part. It is connected to the upper side of the sorting machine housing A to form a vertical shell sorting machine similar to the conventional type.

A thin gutter-like case C having a discharge port 10 on the lower side is interposed between the sorting machine case A and the storage tank B, and the upper end surface of the gutter-like case C has the following features: A slope 4 is formed that slopes downward from the lower edge of the discharge port 2 toward the inside of the storage tank B, and a diamond-shaped overflow port 5 is formed on the slope 4. , a valve body 7 is rotatably supported on a rotation fulcrum 11 at the lower part of the upper side of the opening 5, and a valve body 7 which is pressed against the overflow opening 5 side by a weight 6 is attached so as to be openable and closable.
A torque spring is interposed in the part 1, and its elasticity causes the valve body 7 to
It can also be configured such that it can be pressed against the overflow port 5 side.

Therefore, while the shell particles supplied from the lower part are lifted up by the lifting rotary tube 1 between the sorting screen tube 2 and the lifting rotary tube 1, the small shell particles and dust are removed from the sorting screen tube 2. When the selected shell grains are lifted up, they are thrown into the storage tank B through the discharge port 3 by each discharge vane 8, and the upper surface of the shell grains forms a mountain. However, the upper surface of the shell grain is to some extent above the inclined overflow port 5 which is closed from the lower side by the valve body 7.
Until the shells are placed on top of each other, enough shells can be stored in the storage tank B. When more shells are added, the hem of the top surface of the shells that forms a mountain rises and the shells are placed heavily on the slope 4. Therefore, while the valve body 7 is automatically opened as shown by the imaginary lines in FIGS. 1 and 2 against the pressure exerted by the weight 6, the shell particles overflow from the overflow port 5, and the overflowing shell particles are removed. The grains flow down inside the trough-like case C and are discharged.

[0009]

Effects of the Invention As described above, the present invention has a structure in which the inclined overflow port 5 is closed by the valve body 7 in a state where the shell grains thrown into the storage tank B from the discharge port 3 form a mountain.
The shells can be stored in storage tank B until the hem of the top surface of the shell grains that forms a mountain rises to a certain extent, and it is possible to store enough shell grains without making the storage tank large. Also, overflow port 5
Since it is inclined, the weight of the shell particles can automatically open the valve body 7 properly when more shell particles are being thrown in, allowing the shell particles to pass through the gutter-like case C while overflowing. The gutter-like case C can be installed between the sorting machine case A and the storage tank B to facilitate assembly 4, and the inside of the sorting machine case A can be cleaned with good sorting performance. This means that it can be made into a compact structure, and has the advantage of being able to be suitably implemented with a simple structure.
