Description

[Detailed description of the invention] (a) Industrial application field The present invention is a structure for checking the dehulling rate by taking out a sample of mixed rice immediately after it has been scraped off by rubber rolls in a hulling device.

(b) Prior art In a rice hulling device, it is essential to install an inspection window after the rubber roll for dehulling, take out a sample, and check the dehulling rate. As a structure, one such as Utility Model Publication No. 45-30684 is disclosed.

(c) Problems to be solved by the invention In rice hulling equipment, rice husks are separated from each other by sliding rotation at different circumferential speeds of rubber rolls.
By adjusting the gap between the rubber rolls or the pressing force, the removal rate can be increased or decreased. Mechanically, it is desirable to remove 100% of the husks in one pass through the rubber roll, but in reality, if you try to get more than a certain amount of husks removed, you end up with cracked rice or grains that are misaligned. . However, if the dehulling rate is low, the sorting in the sorting device will be insufficient, increasing the amount of recycled rice, and lowering the efficiency of the entire device. The optimum demolition rate is usually around 85%, and the operator must adjust the rubber roll as necessary to meet this value. In addition, when inspecting only one place on the grain board, the dispersion by the separating plate below the rubber roll is often insufficient, and the dehulling rate varies depending on the location. It is advisable to check.

(d) Means for solving the problems The purpose of the present invention is as described above, and the configuration for achieving the purpose will be explained.

The grain board of the hulling device is tilted toward the mixed rice conveyor side and has a double structure, upper and lower. The upstream grain board is provided with multiple openings in the width direction through which the mixed rice falls to the downstream grain board, and the upstream grain board and downstream grain board are This is a structure of a dehulling rate inspection device in a hulling device, characterized in that a dehulling rate inspection window is provided on the side surface between the grain plates.

Sorted into brown rice and paddy. 7 is a sorting chute section at the outlet of the swinging sorting device, which is swung on the upper surface of each of the 10 sorting plates of the swinging sorting device 6, and separates brown rice, paddy, and mixed rice into each chute. be.

A brown rice sorting device is also configured in the sorting chute 7. 8 is a grain sorting device in which two rotary sorting sieves are arranged. Small-diameter crushed grains and immature grains pass through the elongated hole-like meshes of a constant diameter of the rotary sorting sieve. The exit of fine brown rice grains is on the back side,
Immature grains and crushed grains are dropped downward on the way. 2

Paddy tank shutter opening, mixed rice tank 15
The opening of the shutter can be adjusted using a lever. Furthermore, the tilt angle of the swing sorting device 6 is electrically displayed. A main operation panel 11 is provided on the side of the sorting chute 7, and includes a main switch, a switch for the hulling device motor 17, an abnormality detection lamp, and the like.

The shutter 6c in the swing sorting device 6 is used to flow the unpolished rice part in the direction of the mixed rice and re-sort the rice when the rice is unstable at the start of sorting, 6a, 6b.
is a branching plate movement lever for moving the branching plate for brown rice, mixed rice, mixed rice and paddy from side to side. 34 is an adjustment handle for adjusting the angle of the swinging sorting plate, 44 is a conveyor for taking out immature grains in the suction sorting device, and 50 is a lid for the hole removal rate inspection window of the present invention.

Referring to FIG. 2, the structure not disclosed in FIG. 1 will be explained. Reference numeral 18 is a support frame for the swinging sorting device, which is made of a sturdy framework of shaped steel, and has a crank device, swinging link, etc. inside. Supported.
19 and 20 are rotary sorting sieves of the grain sorting device 8;
A clogging prevention rubber plate 43 is rotated above between the two rotary sorting sieves 19 and 20. Reference numeral 21 denotes an immature rice conveyor of the swinging sorting device 6, which has an opening in the middle, and a waste rice tray is placed under the opening. The fine grains finally come out from the back exit. 26
is a suction sorting fan of the rice hulling device, which further sucks dust from various parts of the rice hulling sorting device and discharges it from the dust exhaust duct 25 to the rice husk chamber. 27, 28, and 29 are brown rice shoots, mixed rice shoots, and paddy shoots.

In this overall configuration, the present invention is constructed as follows.

As shown in FIG. 3, an immature rice conveyor 44 is placed on the side of the suction sorting fan 26 of the mixed rice conveyor 24, and immature rice is pulled by the suction wind.
Going up the flow grain plate 51, the immature rice conveyor 44
to fall.

In the present invention, since the dehulling rate inspection window 50a is provided, the grain grain board tilted upward toward the immature rice conveyor 44 is doubled between the mixed rice conveyor 24 and the immature rice conveyor 44. Conventionally, only the upstream grain plate 51 was sufficient, but in the present invention, a downstream grain plate 52 is provided, and the end of the upstream grain plate 51 is connected to a gap 5 with an interval a.
4 is completed. Upstream grain plate 5
1 is provided with a plurality of openings 51a at regular intervals in the width direction, as shown in FIG. 4, so that the mixed rice falls onto the downstream grain plate 52 evenly and without bias. From this opening 51a, the downstream grain plate 5
The mixed rice that has fallen onto the mixed rice conveyor 24 enters the mixed rice conveyor 24 through the gap 54 having the distance a.

In this basic configuration, when the operator opens the lid 50 of the removal rate inspection window 50a and inserts his hand A to scoop up mixed rice, his finger enters the mixed rice conveyor 24 through the gap 54. The distance a is made smaller than the width of a finger so that it does not get stuck. However, the interval a is such that the mixed rice that falls from the opening 51a always flows into the mixed rice conveyor.
It also consists of

In the embodiments shown in FIGS. 5 and 6, a test box 55 is inserted to collect the sample. The inspection box 55 is provided with a lid 56, and the inspection box 55 is always inserted in the state shown in FIG. 5 with the lid 56 open.
At the time of inspection, the lid 56 is closed using the pivot pin 58 and the lever 59, and the sample mixed rice is dropped into the inspection box 55 through the respective openings 51a and taken out. The same goes for when you put it back in, take it out with the lid on, take a sample and inspect it, and then
When the sample is inserted through the hole removal rate inspection window 50a and the lid 56 is opened, the sample comes out, and the mixed rice that comes in afterwards also comes out freely. 57 is a stopper for stopping the inspection box.

(f) Effects of the invention Since the present invention is constructed as described above, it has the following effects.

First, samples from each part are constantly flowing into the downstream grain board from each opening of the upstream grain board, so samples for the de-hulling rate test can be taken out at any time across the width of the grain board, and each part can be taken out at any time across the width of the grain board. By calculating the average value of the samples, reliability was increased and the rubber rolls were no longer opened or closed too much.

Second, since you can see the mixed rice immediately after it is removed from the hull, you can see the state before it is damaged by conveyor transport, and you can also monitor the state of wind selection and dispersion on the grain board. This is possible.
