Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a test hulling and sorting machine for securing samples of grain-sized brown rice from various types of test unhulled rice.

The test hulling and selection machine that was proposed earlier was the first
As shown in the figure, the test rice input from the raw material paddy input hopper 14 is weighed by the raw material paddy weighing device 15, fried by the raw material paddy thrower 16, and then fed into the raw material paddy feeder 2. , hulling roller 3,
4. The rice passes through the air sorting section 7 and is sent to sorted brown rice/immature grain sorters 9 and 10. The immature grains and sized brown rice sorted here are the sample extraction section where first the immature grains and then the sized brown rice are weighed separately in a weighing device 11, and a sample of sized brown rice is obtained from the sized grain discharge thrower 12. 13. That is, the raw material rice measuring device 15, the hulling rollers 3 and 4, the grading brown rice/immature grain sorting machines 9 and 10, the grading and measuring device 11, and the sample extraction section 13 are arranged in series.

As shown in FIG. 2, the sample extraction section 13 is provided with a rotatable switching valve 21 directly below the grading input port 18, and is branched into an immature grain passage 20 and a grading brown rice passage 22. It leads to the immature grain outlet 19.
A sample take-out side plate 24 fixed to a rotatable shaft 29 and a sample take-out bottom plate 25 fixed to the lower end of the sample take-out side plate 24 are provided in the middle of the sized brown rice passage, and a take-out lever 27 is fixed to the shaft end. ing. A window glass 28 is provided in front of the sample extraction section 13 and slightly above the sample extraction bottom plate 25.
A sample extraction port 26 is provided directly below the sample extraction bottom plate 25 . To take out the sized unpolished rice sample, set the switching valve 21 to the chain line position and open the sample take-out section 1.
3, and observe the sized brown rice that has accumulated on the sample take-out side plate 24 and the sample take-out bottom plate 25 through the window glass 28, then pull the take-out lever 27 and rotate the sample take-out side plate 24 to take the sample. Exit 2
Do this from step 6.

In the figure, 1 is the main body of the test huller selection machine, 5 is the huller case, 6 is the vibrator, 8 is the blower, and 17
23 is the sample extraction case, 23 is the sized brown rice aisle,
And A is a sample retention part.

However, in the unlikely event that you forget to take out this sample, and other unhulled rice for testing is supplied to the test hulling and sorting machine, the same process as above will be followed, and the former sample will be replaced with the later grained brown rice sample. There was a risk of contamination.

In the present invention, the drawbacks of the prior art described above are solved, and by providing a shutter in the grain passage and electrically and mechanically interlocking the shutter and the sized brown rice sample take-out lever, the above-mentioned It is an object of the present invention to provide a self-inspection device that can completely eliminate the inconvenience of mixing samples of different types by locking the shutter.

Embodiments of the present invention will be described based on the drawings.

In the embodiment of the present invention, in addition to the structure shown in FIGS. 1 and 2, as shown in FIG. A proximity switch 31 is arranged on the side surface of the main body 17.

It also has a shutter lock device which serves as a grain channel opening/closing device for the raw paddy measuring device 15 shown in FIG. In FIG. 4, a flat plate-shaped shutter 32 is arranged at the bottom of the raw material rice measuring device 15, and the end of the shutter 32 can be moved in the horizontal direction via a rod 33 by a rack 34 and a pinion 35. An upright lock bar 37 is disposed beside the shutter 32 and is movable downward by a solenoid 36, and is always subjected to an upward pressing force by a coil spring 38. The lock bar 37 has a notch 40 in the center that is hooked to a pawl 39 biased by a spring 43.
The arm 41 fixed to is located at a height that corresponds to a protrusion 42 provided protrudingly from the lower end of the shutter 32. In this way, the sample extraction device is interlocked with the grain channel opening/closing device.

The operation of the embodiment of the present invention having the above configuration will be explained.

When the test hulling and sorting machine is started, or when the take-out lever 27, which had been knocked down to take out a sample of grain-sized brown rice, is raised again, and the magnet 30, which swings at the same time as the lever 27, activates the proximity switch 31, The electric signal is transmitted to the solenoid 36, which moves the lock bar 37 downward against the pressing force of the coil spring 38. Then, the end of the shutter 32, which had been previously locked by contacting the lock bar 37, is released, and the claw 39 is caught in the notch 40 in the center of the lock bar 37.
The lock bar 37 is prevented from rising by the pressing force of the coil spring 38. Next, pinion 3
5 rotates and moves the rack 34 to the right, the shutter 32 is opened via the rod 33, and the weighed paddy rice in the raw material paddy measuring device 15 is transferred to the raw material paddy thrower 1.
Supplied within 6 days. Now, when the shutter 32 moves until it approaches full open, the protruding piece 42 on the lower surface of the shutter 32 pushes the arm 41, thereby rotating the claw 39 fixed to the arm 41 clockwise. Then claw 3
9 is removed from the notch 40, and the lock bar 37 is raised by the pressing force of the coil spring 38. However, the upper end of the lock bar 37 comes into contact with the lower surface of the shutter 32, and this state is maintained with the remaining lifting force due to the pressing force of the coil spring 38 remaining. After the shutter 32 is opened for a certain period of time, the pinion 35 rotates in the opposite direction again, moving the shutter 32 to the left via the rack 34 and the rod 33, and closing the shutter 32. Then, since the shutter 32 has moved to the left, there is no longer anything restraining the lock bar 37 from rising, and the upper end of the lock bar 37 becomes higher than the height of the shutter 32, so that the shutter 32 is locked.

When the unhulled rice thrown into the raw material paddy thrower 16 is removed and sorted by the sorted brown rice/immature grain sorters 9 and 10, first, the switching valve 21 of the sample extraction section 13 is removed.
is made to stand up, and the immature grains and broken rice are passed through the immature grain passage 20 from the input port 18 and are discharged from the sized brown rice/immature grain discharge port 19. When this work is completed, the switching valve 22 is turned down, and the sized brown rice, which has been measured by the grading scale 11, is put into the sample take-out section 13 by the grading discharge thrower 12, and most of the grading takes place through the passage. 2
3 and is discharged from the sized brown rice/immature grain discharge port 19, but a part of the sized brown rice is retained in the sample retention section A. The amount of sample retained is monitored through the window glass 28, the take-out lever 27 is pushed forward at an appropriate point, and the sample is taken from the sample take-out port 26. When the magnet 30 associated with the extraction lever 27 leaves the proximity switch 31, no electrical signal is sent to the solenoid 36, so the shutter 32 remains locked, but again after the sample has been removed. When the take-out lever 27 is returned to its original position, the proximity switch 31 is activated, the shutter 32 is opened, and other types of unhulled rice are hulled and selected. Hereafter, the above action is repeated.

In the test huller selection machine of the present invention with the above configuration and operation, unless the sample extraction work is performed,
Since the next operation is not performed, it is possible to prevent forgetting to take out a sample during continuous operation, and this has the effect of completely eliminating the inconvenience of mixing samples of different types.
