Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain sorting device for determining the quality of paddy.

In the grain sorting device, grains that have been hulled and wind-selected are fed into a sorting tube, immature grains are leaked out from a leak hole on the outer periphery of the rotating sorting tube, and the sorted grains remaining inside are sent to the discharge port of the sorting tube. The quality is verified by opening the valve and weighing the immature grains and the finished grains.The structure is such that each mechanism is automatically controlled as much as possible to improve work efficiency and save labor. be.

So (2)

As a mechanism for opening the discharge port valve of a rotating sorting tube, a mechanical link mechanism or an electric actuation mechanism is known to be operated from the static IE side outside the sorting tube. The transmission mechanism between the rotating command member and the rotating valve is likely to be complicated.

Therefore, the present invention has been devised to eliminate the need for such a complicated transmission mechanism, and for this purpose the following technical measures have been taken. The immature grains (G1) in the rotating different part (force) leak out from a large number of leak holes (6)... and are taken out from the grading hole ((32) is the old discharge port), A valve (11) equipped with a sorting tube (7) K so as to close this discharge port (11), and a drive shaft (4) that drives the sorting tube (force) are connected to the A'+JIJ tube (when the force rotates in one direction) The above valve (
The structure of the grain sorting device is such that the flit closes the discharge port (11), and the valve (10) opens the discharge port (111) in conjunction with the opening/closing link mechanism 2+1 when rotating in the other direction.

As a result of this configuration, the present invention was able to obtain the following technical effects. That is, since the discharge port (11) of the sorting tube (7) is configured to be opened and closed by a valve (IF9 is an opening/closing link mechanism 121 that is linked to the rotational direction of the drive shaft (4)), the valve 11 mark and The opening/closing link mechanism 121) is provided on the force side of the sorting tube (which rotates together), which eliminates the complicated transmission mechanism between the command member on the static fF side and the valve on the rotating side, as in the conventional device described above. In this invention, it is not necessary at all, and the configuration is extremely simple. Moreover, since the opening and closing operation of the valve (16) is performed only by switching the rotation direction of the drive shaft (4), the operation for opening and closing the valve 0θ is easy. It became.

Next, one embodiment of the present invention will be described based on the drawings. Second
The grain sorting device (1), whose principal parts are shown in a vertical front view in the figure and in a vertical side view in FIG. ) The VC1 outer circumferential plate (5) is fitted with a sorting tube (7) made of a thin plate or mesh having a polygonal cross section with many leak holes (6) so that it can rotate freely, and one outer circumference is formed. There is a notch (9) in one part of the plate (8).
) is provided over a length that substantially matches the width direction of the separate cylinder (7), and the outer circumferential plate 00 near the notch (9) and the notch (9)
) and the spacer right side plate (with a rotary link (171 fixed on the axis a protruding outside of the IJ, and a drive arm fixed on the rotary shaft 14) with a long hole along the same direction as +10) 0 (g), and the rotation link 171K [and the pin f?[I] in the elongated hole 1
1'LK: Formed in the opening/closing link mechanism 011 by loose insertion, and the rotating shaft (4) is fixed thereto, for example, Boo+1 143
The second motor is operated by a forward-reversible motor and a belt (not shown).
If it rotates in the direction of arrow E in the figure, the drive arm (marked 1) will also rotate in the same direction and the pin (
21 comes into contact with each other, and the valve (1ω rotates clockwise in the same figure around the shaft (14), so its plate (151) contacts the outer 1 rule (reverse (8)) and the discharge port (11) This valve (IIP) closes +h, and since the opening/closing link mechanism (21) remains immovable after the plate (15i) comes into contact with the drive shaft (
4) In the same direction as the sorting tube (the force will also rotate, the motor will be rotated in the same direction as the counter arrow E shown by the arrow F in Fig. 9).
When rotated in the direction, the other edge (19b
) to pin 4:! 11 abuts, rotates counterclockwise in the same figure around the valve (axis Q4), and the valve 115+ is connected to the outer plate 0ω.
When it comes into contact with the above, the discharge port is opened and the inside of the sorting cylinder (force) is communicated with the outside, and the plate (after the above contact of 151, the opening/closing link mechanism r21) becomes immobile and is driven @(4). The sorting tube (7) also rotates in the same direction as the rotation center of the sorting tube (7).Therefore, the polished rice is fed from the input hopper 24) whose lower opening is visible near the center of rotation of the sorting tube (7). Well, second
When the sorting cylinder (7) rotates in the direction of arrow @E in the figure, the leak hole (6)
) ... leaks out of the sorting tube (7) and enters the sorting process, and when the leakage of immature rice (Gl) is finished, the arrow F in Figure 5
While rotating the sorting cylinder (7) in the direction, the valve (IFD is opened and the sorted particles 0) are taken out from the discharge port (11), resulting in a discharge process.

The sorting cylinder (7) K in the illustrated example has a particle size adjustment (02) in the leak hole (6).
) is equipped with a clogging prevention body (c) to push it back into the sorting cylinder (force) when it becomes clogged. The structure is such that the clogging prevention function slides against the rotating sorting cylinder (power outer peripheral plates (5)...(8) as shown in the enlarged view in Figure 4, and the solid line in the figure shows the shape during the sorting process. In addition, the two-dot chain line in the figure shows the shape during the ejection stroke.

The illustrated sample hulling grain sorting device is shown in Fig. 1 as a top view of the entire device, and in Fig. 6 as a flowchart showing the main steps. Paddy thrower m that is automatically weighed in the appetizer section and rotates in the direction of the arrow! The rice is lifted up to the feeder (A) by the FQK, and is hulled by the Naro hulling section (7) using, for example, rotating left and right hulling rolls that operate for a predetermined four-layer time. The husks of the hulled rice are discharged to the AA ocher direction by the winding section 311, and the brown rice is put into one of the sorting tubes (71 (7)) of the grain sorting section G2 for a predetermined grain sorting time. The immature grains (G1) leak out from the leakage hole (5) on the outer periphery of one of the sorting cylinders (7) rotating in the direction of the arrow E over the period of time, and are automatically weighed in the measuring section C1i. The finished immature grains (Gl) are led to the immature sample take-out port through the sample thrower C34)lcchi1z full switching valve c3Q rotating in the arrow direction.

Also, when the rotation for the predetermined grain sorting time is finished, the right sorting cylinder (
The force valve [16] opens and the remaining sized particles (G2) flow down to the measuring section (c), and are taken out to the rectified sample outlet c3n via the sample changeover valve 09 at the sample thrower (b). It is something that In addition to the illustrated example, the opening/closing link mechanism 11) may be constructed by replacing it with a member having a function similar to that described above.
