Description

[Detailed Description of the Invention] In a grain drying and conditioning storage facility generally called a rice center, a large amount of grain harvested by each farmer is collected and processed. In this case, the grains of each farmer are collected and mixed. First, a small portion of each grain is taken as a sample, and after drying, the sample is removed and the quality of the grain is tested.

The present invention relates to a device for removing such a small amount of sample grain and verifying its quality, and includes a weighing device for measuring the weight of the sample supplied to the device, a removing device, a grain sorter, and a grain sorting device. Alternatively, a discharging scale for measuring the weight of waste grains, a grading receiver, and a waste grain receiver can be integrated in sequence to quickly perform quality inspections such as grain grade, yield, weight ratio of sized grains and waste grains, etc. The aim is to do it efficiently in a timely manner.

In addition, in the present invention, when the removal is incomplete after passing through the removal machine once, the sample discharged from the removal machine is returned to the removal machine once again to completely remove the sample, and then the sample is printed once with one verification device. The purpose is to make it possible to arbitrarily select the number of times of rubbing twice, and to completely remove the sample while preventing the occurrence of crushed grains.

The present invention will be explained based on the embodiment shown in the drawings. Reference numeral 1 denotes a sample input hopper which opens in the side wall of the machine frame 2, and below the discharge port which has an on-off valve 3,
Look into the sample receiver 5 of the scale 4 for loading.

The weighing scale 4 suspends a support rod supporting a sample receiver 5 with a spring, converts the displacement of the sinking support rod into an electric quantity, and digitally displays the weight of the sample.

The discharge port of the sample receiver 5 is connected to the lower intake port 8 of the charging thrower 7 via the charging opening/closing valve 6, and the upper outlet of the thrower 7 is connected to the supply hopper 10 of the removing machine 9.

The removing machine 9 has a pair of parallel rubber rolls 11 and a blower 12 for blowing air.

There are two grain sorters 13 and 14 below the demasher 9.
are arranged side by side on the left and right, and an intermediate hopper 15 communicating with the lower intake port of the thrower 7 is installed in the center thereof,
The bottom discharge port of the remover 9 is connected to two grain sorters 13 and 14 or an intermediate hopper 15 via a three-way switch 16.
Switchable connection to one of the following.

The outlet of the intermediate hopper 15 is equipped with a return on-off valve 17, and when the on-off valve 17 is closed, a switch 16
is connected to the intermediate hopper 15, and the on-off valve 17
When the selector 16 is open, the selector 16 selects the grain sorter 13 or 14.
The on-off valve 17 and the switching device 16 are interlocked so as to be connected to.

The grain sorters 13 and 14 rotate polygonal sorting cylinders made of perforated plates, and separate the shelled grains supplied into the cylinder into regular grains and waste grains.

Next, the discharge ports opened at the bottom of the grain sorters 13 and 14 are connected to the sample receiver 21 of the discharge scale 20 (same structure as the loading scale 4) via the on-off valves 18 and 19, respectively. Furthermore, the discharge port of the sample receiver 21 is connected to the take-out hopper 23 via the discharge thrower 22, and the discharge port of the hopper 23 can be freely switched to either the particle size receiver 25 or the waste particle receiver 26 via the two-way switch 24. Connecting.

The above-mentioned on-off valves 3, 6, 17, 18 and 19,
The direction changers 16 and 24 are operated by solenoids, and 27 indicates an electrical unit that controls them. 28 is a dust suction tube of the take-out hopper 23, and its terminal end is connected to the blower 12.

A sample of grain, for example a smaller amount (approximately 500 g) than paddy, was taken from a certain farmer and brought into the storage facility, fed to the input hopper 1, opened the on-off valve 3, stored in the sample receiver 5, and its weight was weighed for loading. Measure with instrument 4.

After the measurement, the tensioning on-off valve 6 of the measuring instrument 4 is opened, and the sample paddy is supplied to the demasher 9 through the tensioning thrower 7.
The rice husks are removed between a pair of rubber rolls 11 and discharged outside the machine by a blower 12.

If 100% removal can be achieved by just passing through the demolder 9 once, that is, by just one rubbing, within a short period of time after opening the on-off valve 6 of the measuring instrument 4 until the sample reaches the desorber 9, for example. After 1 second, intermediate hopper 15
The three-way switching device 16, which is on standby and facing the 3-way switch 16, is actuated to switch its direction to the grain sorter 13, 14 side, and the sample discharged from the remover 9 is supplied to either the left or right grain sorter. At this time, the return on/off valve 17 of the intermediate hopper 15 is opened in conjunction with the switch 16, but since the switch 16 has been switched to the grain sorter side, all the sample after removal is transferred to the grain sorter 13. Or it enters 14 and never enters stakeout thrower 7.

Then, the waste grains contained in the sample after removal are separated by the grain sorters 13 and 14, and collected at the bottom of the grain separator. After a suitable time has elapsed, the on-off valve 18 or 19 is opened, and all the waste grains are removed from the weighing device 20. The sample flows out into the sample receiver 21 and its weight is measured.

After measurement, the waste particles are discharged from the sample receiver 21 through the thrower 2.
2. After passing through the take-out hopper 23 and the two-way switch 24, the particles are discharged and stored in the waste container 26.

After the waste grain discharge is completed, the grain sorter 13,1
After reversing the sorting cylinder No. 4 and discharging the sized particles remaining in the cylinder, and measuring the weight with the discharge weighing device 20 in the same manner as described above, the two-way switch 24 is switched to the grading receiver 25, and the sized particles remaining in the cylinder are weighed. is discharged into the grading tray 25 and taken out.

Depending on the type of grain, if it cannot be completely removed by one-time rubbing, it may take a long time, e.g. 90 minutes, after opening the on-off valve 6 of the measuring device 4 until all of the sample sample is discharged from the removing machine 9. For a second, the three-way switch 16 is fixed at the standby position shown in FIG. While the three-way switch 16 is connected to the intermediate hopper 15 in this way, the return on/off valve 17 of the intermediate hopper 15 is closed, so the sample discharged from the remover 9 is temporarily stored in the intermediate hopper 15. accumulates in

After 9 seconds have elapsed and all the sample samples have been stored in the intermediate hopper 15, the return on/off valve 17 is opened and the three-way switch 16 is switched to the grain sorter 13 or 14 side at the same time.

As a result, the sample that has been rubbed once flows down into the lower intake port 8 of the loading thrower 7, is returned to the de-machine 9 by the thrower 7, is rubbed twice, and then passes through the three-way switch 16 to the grain sorter. 13 or 14.

After sorting, the weights of the sized grains and waste grains are measured in the same way as the above-mentioned one-time rubbing, and the grains are taken out into the sized grain receiver 25 and the waste grain receiver 26, respectively.

In this way, whether to rub once or twice is determined by turning the three-way switch 16 from the intermediate hopper 15 in the standby position from the time when the loading on-off valve 6 of the metering meter 4 begins to open. The time required to switch to the sorting machine 13 or 14 and open the return on-off valve 17 in conjunction with the switching, that is, the direction switching time, can be arbitrarily shortened (1 second) or lengthened (9 seconds). Select. This direction switching time is automatically set using a sequence or a microcomputer.

In the embodiment shown in the drawings, the three-way switch 16 is switched to alternately use the two grain sorters 13 and 14 to increase efficiency, but it goes without saying that one grain sorter is sufficient.

Therefore, the yield of the grains harvested by the farmer can be determined from the ratio of the weight of the sample sample measured by the weighing scale 4 and the total weight of the grains and waste grains measured by the discharge scale 20. The weight ratio of the grains and waste grains is determined by the weight of the grains, and the grade of the grain is determined from the grain size taken out into the grain size receptacle 25, and the quality is verified.

In summary, the present invention provides a sample input hopper 1.
The sample receptacle 5 of the tensioning scale 4, which looks downward, is connected to the lower intake port 8 of the tensioning thrower 7 via the tensioning on-off valve 6, and the upper outlet thereof is connected to the removing machine 9. The bottom discharge port of the remover 9 is switchably connected to either the grain sorter or the intermediate hopper 15 via a direction switch, and the discharge port of the intermediate hopper 15 is connected to the charging thrower 7 via a return on/off valve 17. It is connected to the lower intake port 8, and the discharge port at the bottom of the grain sorter is connected to the sample receiver 22 of the discharge measuring device 20, and the discharge port is connected to the grain sorting receiver 25 or the waste grain receiver 2.
6, and the return on/off valve 1
When 7 is closed, the direction switch is on the intermediate hopper 15 side,
In addition, when the return on-off valve is open, the directional switch is connected to the grain sorter side, so that the return on-off valve 1
7 and a direction switch are interlocked.

Therefore, in the present invention, the input hopper 1, the measuring device for loading 4, the de-machine 9, the grain sorters 13, 14, the measuring device for discharging 20, the grain sorting receiver 25, or the waste grain receiver 2
6 are connected sequentially and integrally, so just by putting in the sample grain, all the weighing, dehulling, and grain sorting necessary for quality inspection can be performed, and the grain grade, yield, grading, and waste grain weight can be checked. This has the effect that quality tests such as ratios can be performed efficiently in a short time.

Moreover, in the present invention, the de-machine 9 is connected to the grain sorter side and the de-machine 9 via a three-way or two-way directional switch.
Switchably connect to the intermediate hopper 15 side that returns to
Since the discharge port of the intermediate hopper 15 is provided with a return on-off valve 17 that is linked to a direction changer, the direction changer can be turned off within a short period of time from opening the loading on-off valve 6 until the sample reaches the demolder 9. If you switch to the grain sorter side, it will be rubbed once, and if you fix the direction changer in the standby position on the intermediate hopper side until a long time has elapsed until the sample is all discharged from the desorber 9, the sample after desorbing will be All of them go back to the depressing machine 9 once again and are printed twice.
In this way, by simply setting the direction switching time of the direction changer to be long or short, you can arbitrarily select one-time rubbing and two-time rubbing with one and the same device. By performing hard grinding, damage to the grains such as crushing is prevented and completely removed, resulting in the effect that quality tests such as yield surveys can be performed accurately.
