Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a grain inspection device.

(Prior Art) In the publicly known Japanese Patent Laid-Open No. 58-34046, when a test paddy of a specified capacity is collected from each farm and put into a paddy weighing machine, a test pad of the specified capacity is obtained. Since the time required for the lifting action in the thrower and the removal / wind separation action in the huller can be made constant,
Subtracting the required time (for example, 20 seconds) from the desulfurization / air-selection supply from the timer setting time (for example 60 seconds) can determine the sorting time of the grain sorter. The technique is described in which the selective use of the can be regulated at any predetermined time.

Further, in the publicly known Japanese Utility Model Publication No. Sho 57-47092, there is described a rotary sieve which does not discharge in forward rotation but discharges in reverse rotation.

(Problems to be Solved by the Invention) As described in the above-mentioned publicly known publications, the harvested rice from each farmer is often brought into a centralized adjustment processing facility for adjustment processing. At the above processing facility, a part of the grain that has been brought in is collected as test paddy for quality inspection from the work procedure, and a rating such as first-class rice or second-class rice is paid, and a considerable amount of money is paid. It is customary. As for the grain inspection device used at that time, in the conventional device, the grain inspection is performed by collecting a prescribed volume as described in JP-A-58-34046.

And, since the test paddy has a constant specified capacity, the time required for the lifting operation in the thrower and the de-airing / wind-selection operation in the huller are naturally constant, therefore
Subtracting the time required for wind selection supply from the timer setting time gives the sorting time of the grain sorter.So, if you adjust the timer setting time and decide it, the sorting time of the grain sorter will be determined. The idea is to be.

However, the above-mentioned known technique has a problem. For example, the test paddy collected from each farmer may have been weighed in 550g even though it has been determined to be constant, because there is a mistake in measuring it or there is a difference in feeling. The known example is provided with a paddy weighing machine for weighing the input test paddy, but the paddy weighing machine only weighs the loaded test paddy, and only knows that it was 550 g, No measures have been taken.

In view of this, the present invention is designed so that an appropriate amount is sampled from the beginning and a grain test is conducted, and a sorting time corresponding to the amount can be automatically set to ensure fairness.

(Means for Solving the Problems) Accordingly, the present invention provides a weighing device for weighing an appropriate amount of a supply sample, a hulling device for hulling a supply sample, and a rotation for selecting immature rice from hulled hulled material.

Further, the present invention is a weighing device for weighing an appropriate amount of a supply sample, a hulling device for hulling a supply sample, a rotary sieve for sorting scrap rice from hulled hull material, and a weighing for weighing selected grains. The rotary sieve is provided with an on-off valve that automatically closes the outlet during normal rotation to select unripe rice and automatically opens the outlet during reverse rotation to release fine grains. And a grain verification device provided with a rotation mechanism capable of performing a normal rotation for a standard sorting time determined according to a measured value in the weighing device, and having an increasing / decreasing mechanism provided in the rotation mechanism for increasing / decreasing the standard sorting time.

A shutter 22 that goes in and out of the return pipe 20 is provided in the upper and lower portions of the return pipe 20.

The rotary sieves 3 and 4 are formed in a perforated polygonal tube for selecting unripe rice, and an outlet 23 is opened in a part of the outer peripheral wall, and the outlet 23 is automatically closed at the time of forward rotation, and the reverse rotation is performed. An on-off valve 24 that automatically opens this outlet 23 is installed at this time.

In FIG. 3, 27 is an operation unit, 28 is a power switch, 29 is a hulling number switching switch, 30 is an alarm stop push button, 31 is a function key group, and 32 is a ten-key group.

FIG. 4 shows the relationship between the amount of the supplied sample and the control of the standard rotation time of the rotary sieves 3 and 4, the vertical axis represents time, and the horizontal axis represents the sample supply amount. From FIG. 4, when 500 g of the sample is charged, the rotary sieves 3 and 4 are rotated for 60 seconds.

In the figure, 47 is a fine grain cup, 48 is an immature grain cup, 49 is a switching gutter, and 50 is a shaft stopper of a 17 switching device.

(Operation) A method of using the above device will be described.

Turn on the power switch 28 to energize each part, adjust the number of times of hulling switching 29 to the scale of 2 times, and start key
33 and the zero reset key 36 are pressed, and the sampled paddy rice is put into the supply hopper 6. In this case, the amount of input is not constant and may be large or small.
Weighed by

That is, when the sample paddy rice is put into the supply hopper 6, for example, the input gate 14 is opened for 5 seconds, the introduced sample flows into the sample weighing box 13, and is weighed by the weighing device 7.

If this metric is, for example, 700 g, it means 70 seconds corresponding to 700 g from the table of FIG. 4, and if it is 600 g, it means 60 seconds corresponding to 600 g from the table of FIG. 4, This time becomes the standard rotation time of the rotary sieves 3 and 4 with respect to the input amount (supply amount), and is automatically set.

Therefore, since the sorting time corresponds to the input amount, even if the input amount changes, fair selection can be performed. That is,
The selection with the rotary sieves 3 and 4 is to select immature sheets (waste rice) mixed in the good grains, but with the use of the rotary sieve, the waste rice is selected as time is spent. So you have to keep the time constant.

Therefore, in the known example, the input amount and the selection time are both kept constant to ensure fairness, but since it is difficult to make the input amount constant, the present invention sets the selection time corresponding to the input amount, Even if the input amount changes, the selection time is automatically set according to the input amount to ensure fairness.

However, among the rice grains produced, the quality is generally inferior, so accurate grade determination is impossible with normal sorting time, and when it is judged that it is better to sort more than usual, it is Pressing the PLUS key 42 once will increase the sorting time for 5 seconds (pressing it twice will increase it by 10 seconds) for even more fairness. On the contrary, when it is judged that the quality of the produced rice grains is very good and it is not necessary to perform the sorting according to the normal sorting time, the minus key 43
Press once to shorten the sorting time for 5 seconds (press twice to enter 10
Seconds are shortened), and more fairness is expected.

Then, explaining according to the time chart of FIG. 5,
The metering gate 16 opens for 11 to 16 seconds, flows into the tension hopper 12, and then flows from the thrower 11 into the supply tank 9. The hulling roll 8 rotates for 11 seconds to 47 seconds, and what has been hulled by 32 seconds returns from the return pipe 20 to the tension hopper 12 and circulates to the supply tank 9 through the lowerer 11 to hull the rice. Is performed.

The rotary sieves 3 and 4 start normal rotation at 27 seconds when the metering gate 16 is open, perform normal rotation for 80 seconds up to 1 minute 47 seconds, and stop for 10 seconds.
Reversed for 2 minutes and 12 seconds.

Meanwhile, the scrap rice sorted by the rotary sieves 3 and 4 falls by its own weight, flows into the weighing section 5, is weighed and printed, and is stored in the immature rice container 48 by the thrower 25. After about 10 seconds, the measurement of the unripe rice is completely finished, so that the measurement of fine grains is performed, and the similarly measured grains are stored in the fine grain cup 47.

The column for the start of one pass in FIG. 5 is based on the above.

(Effect) As described in Japanese Patent Application Laid-Open No. 58-34046, the conventional grain inspection device has conducted a grain inspection by collecting a prescribed volume. If the test paddy has a certain specified capacity, the grain lifting action in the thrower and the removal / removal in the grain huller
Since the time required for the wind-selecting action is naturally constant, subtracting the time required for frying, removing, and wind-selecting from the time set by the timer gives the sorting time for the grain sorter, so even the time set by the timer can be adjusted. Then, the sorting time of the grain sorter can be determined. However, the amount of test paddy collected from each farm is
Even if it was decided to be constant, the amount of test paddy could not be made constant because there was a mistake in measurement or a feeling. Although the known example is provided with a paddy scale for weighing the input test paddy, the paddy scale only measures the input test paddy and does not adjust it.

Accordingly, the present invention is a weighing device for weighing an appropriate amount of a supply sample, a hulling device for hulling a supply sample, a rotary sieve for sorting immature rice from hulled hulls, and a weighing for weighing selected grains. The rotary sieve is provided with a rotating mechanism capable of rotating and sorting for a standard sorting time determined according to a measured value in the weighing device, and the rotating mechanism is capable of increasing or decreasing the standard sorting time. Since this is a grain verification device equipped with a mechanism, it is possible to supply an appropriate amount of sample, so there is no measurement failure.

Since the rotary sieve is rotated for a predetermined standard sorting time according to the measured value in the weighing device, accurate sorting can always be performed.

Since the rotating mechanism of the rotary sieve is provided with an increasing / decreasing mechanism that can increase / decrease the standard selection time, more accurate verification can be performed.

Further, the present invention is a weighing device for weighing an appropriate amount of a supply sample, a hulling device for hulling a supply sample, a rotary sieve for sorting scrap rice from hulled hull material, and a weighing for weighing selected grains. The rotary sieve is provided with an on-off valve that automatically closes the outlet during normal rotation to select unripe rice and automatically opens the outlet during reverse rotation to release fine grains. And a grain verification device provided with a rotation mechanism capable of performing a normal rotation for a standard sorting time determined according to a measured value in the weighing device, and having an increasing / decreasing mechanism provided in the rotation mechanism for increasing / decreasing the standard sorting time. Therefore, since the rotary sieve is rotated forward for the standard sorting time that has been set, it is possible to accurately select even a configuration in which immature rice is selected during normal rotation and automatically discharged during reverse rotation. it can.

Has the effect.
