Description

[Detailed description of the invention] The present invention relates to a rice sorting machine for testing.

In other words, a test is carried out by removing a small amount of brown rice that has been hulled at a hulling plant, etc., and selecting the rice for testing. It is an object of the present invention to provide a method that allows the remaining fine grains to be taken out quickly and smoothly and has a simple structure so that it can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

A is a small cylindrical sorting tube with a sorting hole 1 formed over almost the entire circumference, and one end of the sorting tube A is connected to the large diameter side of a truncated conical annular body a with an opening 2 on the small diameter side. Four guide vanes 3, which are inclined in the same way with respect to the axial direction, are fixed to the inner circumferential surface of the annular body a so as to be long enough to completely straddle the axial direction of the annular body a, and a sorting tube is formed. On the other end side of A, a boss 6 supported by a support arm 5 is installed, and a rotating shaft 7 is fitted onto the boss 6.

A metal 9 is installed on the side of the cover frame 8 that houses the sorting tube A, and the rotary shaft 7 is rotatably mounted on the metal 9. Tilt it slightly lower and rotate the rotation axis 7.
A belt 12 is wound around a pulley 10 attached to the tip of the motor M and a pulley 11 of a forward/reverse motor M located below, so that the motor M rotates in the forward direction for a certain period of time and then automatically reverses for a certain period of time by the operation of a timer. be installed and configured.

A supply tank 13 is also provided on the other side of the cover frame 8.
is installed so that the tip end 14 of the supply tube 4 extending from the lower part of the supply tank 13 looks inside the annular body a, and a receiving gutter 15 is installed below the sorting tube A. A container 16 is visible below the annular body a, and an outlet 18 is extended outward from a receiving gutter 17 installed at the lower part of the opening 2 of the annular body a.

When brown rice for testing is supplied to the supply tank 13 for rice selection, the motor M first rotates the sorting tube A in the normal direction as shown by arrow A. The brown rice discharged into the annular body a is forcibly fed into the sorting cylinder A by each guide vane 3 as shown by the arrow B, and since the annular body a has a truncated conical shape, The brown rice, which is not spilled from the opening 2 side and is fed inward in the direction of arrow B, is sorted by the sorting cylinder A, and the crushed grains and small rice leak through the sorting hole 1 and fall into the receiving gutter 15 below. A certain amount of brown rice is then received into a container 16 and sorted.

After a certain period of time for sorting has elapsed, a timer is activated and the motor M is reversed, and the sorting cylinder A is also reversed as shown by arrow C. Thereupon, the brown rice remaining in the sorting cylinder A is separated into different parts. Guide vane 3
As shown by arrow D, the paper is forcibly fed toward the opening 2 and sent out from the opening 2, and then falls into the receiving gutter 17 below and is taken out from the outlet 18.

In this way, the present invention provides a small cylindrical sorting tube having a large number of sorting holes on its circumferential surface, which is horizontally mounted on an axis so as to be freely reversible in the forward and backward directions, and one end of the sorting tube is a truncated conical sorting tube whose outer end is open. A plurality of guide vanes inclined in the axial direction are each fixed on the inner peripheral surface of the annular body, and a supply cylinder is inserted from the outside toward the inside of the annular body. Because of the extended installation, when you take out a small amount of unhusked brown rice at a hulling plant, etc., select it, and perform a test, if you rotate the sorting tube in the normal direction and feed the brown rice from the supply tube, the rice will be shaped like a truncated cone. The annular body prevents the brown rice from spilling, and each guide vane forces the brown rice into the sorting cylinder to ensure good sorting.
When discharging the brown rice remaining in the sorting cylinder, by reversing the sorting cylinder, each guide vane can quickly and smoothly send out the fine grains inside to the opening side, allowing for good discharge. It is possible to reliably and satisfactorily supply a certain amount of brown rice, sort it, and then take it out, and has the feature that it can be carried out suitably with a simple structure.
