8, details of which are omitted, but inspection and traits, specifically colored grains, immature grains, dead rice and cracks in the body, etc. are received by inputting each measurement light of transmission or reflection after receiving one grain of brown rice sized grains. Inspection is possible for each grain. Once all of the sizing is once received by the quality measuring device 38, the sizing is carried out one by one to the measuring position by the normal rotation of the unillustrated one-grain transport mechanism, and the sizing is inspected in a non-destructive state and then moved out of the path. The surplus sized particles are dropped at once by the reversal of the single-grain transport mechanism, and can be collected together with the inspection particles in the collecting hopper 41 for discharging in a downward direction. It is configured to be supplied to the sample sealing device C by the shutter 42 and the discharge lower 43.

[0007] In addition, the paddy and debris samples waiting in the waiting boxes 39, 39.

Denotes a motor for driving the discharge thrower 43. The sample sealing device C is configured so that the same sample can be successively accommodated in a configuration in which the film fed out continuously is sealed in the shape of a bag, and the sample is sorted and packed in the order of paddy, refuse granules, and sized samples. . Reference numeral 45 denotes a belt conveyor that conveys the sample accommodating bag that is continuously fed out to a predetermined position.

The control device D includes an operation unit 46 and a CR.
It comprises a T screen 47 and a built-in control unit 48, of which the operation unit 46 has a configuration in which individual information such as the consignee code, date, type, and the like can be input. The control unit 48 outputs a control signal to drive the driving motors, shutters, measurement units, and the like of the respective units of the sizing yield inspection device A, the quality inspection device B, and the sample sealing device D at the same time. , While performing the calculation of the sizing yield and the bulk weight for the paddy weight while inputting the quality measurement data signal and the like, and storing it in the storage unit,
A comparison is made with each grade of the agricultural product standard previously stored in the storage unit to determine which grade the sample brown rice corresponds to. The CRT screen 47 is configured to display a confirmation screen of operation input information from the operation unit 46 and other necessary information. In addition, the control unit 48 activates a printer (not shown) provided in the sample sealing device D, prints the sizing yield, volumetric weight, and quality for each consignee, and encloses the sizing in the sizing container. are doing.

The operation of the above example will be described. A predetermined paddy sample is supplied to the input hopper 5 of the sizing yield tester A,
Individual information is input through the operation unit 46. The device is running or optionally activated, and the paddy sample is supplied to the sample storage bucket 2. Usually, a plurality of sample paddies will be supplied sequentially. When the storage bucket 2 is raised to a predetermined position, the opening / closing plate 6 is opened and the sample inside is discharged to the supply hopper 8. First, a part of the paddy overflows from the overflow port to the second guide chute 14 side. The opening and closing shutter 9 is opened in anticipation of a stable state, and the remaining paddy is tilted guide chute 1
Through zero, it reaches the weighing hopper 11. Here, the total weight is measured.

A switching cylinder 20 connected to the fry slotter 15
Switches from the second posture C to the first posture B, and the overflow paddy enters the waiting box 39 via the switching cylinder 20 in the second posture C and stands by. After that, the switching cylinder 20 assumes the second posture C, and supplies the weighed sample paddy to the drying unit 21. In the removal unit 21, a pair of removal rolls 2
The brown rice is de-spinned once or twice by 2, 22, and the brown rice is supplied to one of the empty rotary sorting cylinders 24 via the switching chute 23. By the rotation of the rotary sorting cylinder 24, the dust particles are separated into sized particles. First, the dust particles reach the measuring hopper 11 and are weighed, and are stored in the standby box 39 via the switching cylinder 20 in the second position. Next, the sized particles are accumulated in a state where they are blocked by the discharge gate 12 of the weighing hopper 11 while being supplied to the quantifying hopper 29, and the total of the quantified hopper 29 and the gate sized particles is measured. These weighing data are input to the control unit 48 and the sizing yield is calculated from the sizing weight with respect to the paddy sample weight.

When the discharge gate 12 is opened, the gate sized particles are discharged, and the excess sized particles removed by the dispensing member 30 are also discharged. The sized particles remaining in the fixed amount hopper 29 are blocked by the discharge gate 12 closed immediately before by the opening operation of the discharge shutter 31, and are weighed. The weighing data is input to the control unit 48, and a volume weight w / v is obtained from the known volume v of the quantitative hopper 29 and the weighing result w.

The sized granules overflowing and the sized granules in the fixed amount hopper 29 are merged and conveyed upward by the fry-slower 15. At this time, the switching valve 40 of the guide tube 36 is in the closed state of the passage and the sized granules are formed. Is supplied to the quality measuring device 38. When the character / quality is measured by the quality measuring device 38, the ratio of the colored particles and the ratio of the cracked particles mixed in the sizing are calculated.

The sized particles passing through the quality measuring device 38 are sequentially collected in the lower collecting hopper 41. During this quality measuring period, the paddy / dust particles samples waiting in the waiting boxes 39, 39 are supplied to the discharge slotter 43. Then, the process reaches the final stage, the sample sealing device C, and is individually bagged.
In the sample sealer C, the sizing process is the last step, and the sizing / yielding ratio of the sizing / paddy weight, the ratio of the sizing weight to the swarf weight, the volume weight, the trait quality , Are printed out together with the individual data.

From the above data, it is possible to easily determine which grade brown rice belongs to by looking at the bulk weight and the trait quality, and to eliminate errors caused by visual determination.

[0015]

According to the present invention, there is provided a bulk-weight tester E for receiving a sized brown rice obtained by dehulling and grain-sorting a sample paddy and measuring its bulk weight, and a trait and quality of the sized brown rice. And a controller for judging which class belongs to by comparing these measurement results with a preset bulk weight standard and a standard of quality. Has the effect that it can be performed quickly and without error. In addition, a scale 13 for measuring the sample paddy
Is configured to weigh swarf and sizing, and to weigh
Therefore, the simplification of the device can be achieved by using the measuring device 13 as well.
Cost can be reduced.
