Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a self-testing device using a test huller for securing samples of grain-sized brown rice from various test unhulled rice.

As a test huller selection machine, the one shown in FIG. 1 has already been proposed. In FIG. 1, the test rice introduced from the raw material paddy input hopper 14 is weighed by the raw material paddy weigher 15, and then
The grain is discharged onto the gutter 19 by a discharging mechanism (not shown), fried by the raw material paddy thrower 16, fed into the raw material paddy feeder 2, and passed through the hulling rollers 3, 4 and wind selection section 7. Grained brown rice/unripe rice sorting machine 9,10
The unripe rice and the sized brown rice that are sent to and sorted here are weighed first by the unripe rice and then by the sized brown rice separately using a weighing device 11 to obtain a sample of the sized brown rice. The sample is supplied from the discharge thrower 12 to the sample extraction section 13 . That is,
A self-inspection device has been proposed in which a raw paddy measuring device 15, hulling rollers 3, 4, grading brown rice/unripe rice sorting machines 9, 10, grading measuring device 11, and sample extraction section 13 are arranged in series. .

By the way, in this test hulling and sorting machine, when the test rice is weighed by the raw material paddy weighing device 15 and fed into the raw material paddy feeder 2, in the unlikely event that the flow of the test rice is poor, etc. Even if some of the rice remains in the weighing hopper, there is no device to automatically check this, and if test rice of many varieties is subsequently fed into the raw material input hopper 14,
There is a risk that different types of test rice may be mixed into the obtained sample, and it is extremely troublesome to inspect the inside of the weighing hopper one by one to prevent this.

The present invention solves the above-mentioned drawbacks, and by attaching a residual rice detection device to the raw material rice measuring device 15 and subsequently providing a flow path blocking device that interlocks with the residual rice detection device in the flow path, The purpose of the present invention is to provide a self-inspection device that completely separates the rice grains and improves the reliability of the test huller sorting machine.

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

FIG. 2 is a cross-sectional view of an embodiment of the invention. Raw material paddy measuring device 1 of the test hulling and sorting machine shown in Fig. 1
5 has a new residual rice detection device 17 installed.
On the other hand, a shutter 18 is provided as a flow path blocking device at the bottom of the raw material paddy feeder 2 located on the upper part of the main body of the test hulling and sorting machine, and the shutter 18 is configured to interlock with the residual rice detection device 17.

In the above configuration, the operation will be explained. First of all,
When you press the start switch (not shown), shutter 1
8 is fully closed. The test rice input from the raw paddy input hopper 14 is weighed by the raw paddy weigher 15,
The raw material paddy feeder 2 is connected to the raw material paddy feeder 16 by the raw material paddy thrower 16.
The grain is fried and temporarily stored here. Next, the residual rice detection device 17 detects the presence or absence of residual rice in the weighing hopper based on the weight and displacement of the weighing hopper, and if there is no residual rice, it sends a signal to the shutter 18 to open the shutter 18 and release the raw material. The test rice in the rice feeder 2 is sent toward the hulling rollers 3 and 4. In the unlikely event that there is rice remaining in the weighing hopper, use the shutter 18.
remains closed, and the operation manager of the test hulling and sorting machine removes the remaining rice in the weighing hopper or automatically causes the weighing hopper 15 to perform the discharging operation again to discharge the remaining rice. The shutter 18 is opened only after the detection device 17 confirms that there is no rice remaining in the hopper. After the shutter 18 is opened for a certain period of time, it automatically closes again to prepare for the next test rice input.

As described above, according to the self-inspection device using the test hulling and sorting machine of the present invention, it is possible to determine the presence or absence of residual rice in the raw material paddy measuring device, and if there is any residual rice, By automatically blocking the distribution of test rice, it has the effect of preventing different types of test rice from being mixed together.

In addition, in the above embodiment, a shutter was provided at the outlet of the feeder for raw material paddy as a flow path blocking device, but
The flow path blocking device may be provided in any part of the rear flow path of the raw material paddy weighing device, and its configuration may include a spare tank provided in the shunt in addition to the shutter.
As the residual rice detection device, a support value of a raw material paddy measuring device, a photoelectric sensor, etc. can be used.
