Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sample hulling grain sorting device for determining the quality of paddy.

The sample paddy put into the hulling grain sorting device is first weighed,
The rice is hulled in the hulling section for a certain period of time, the rice husks are discharged by wind sorting, and the brown rice is fed into the grain sorting section.In the grain sorting section, the grain sorting cylinder is rotated for a certain period of time to leak and separate immature grains. Then, the immature grains and the sized grains remaining in the grain selection tube are weighed. The grain selection time, which mainly consists of the rotation time of the grain selection tube, was determined by the operator based on the weighed value of the paddy and set it on a timer, so due to For example, there are problems such as leakage of immature grains, insufficient separation, or conversely, the problem of continuing to rotate the grain selection tube even though the separation of immature grains has been completed.

It has also been found that when the input amount of paddy is large, for example, by increasing the hulling time and the driving time of the sorting cylinder accordingly, the grain sorting operation can be carried out without excess or deficiency. In order to solve the above conventional problems, the following technical measures were taken.

That is, the paddy input into the device as a sample is transferred to the paddy measuring section (2).
), the hulling section (5) is busy and the hulling is carried out, and the grain selection tube (
7) In a sample hulling grain sorter configured to carry out K grain sorting (G2) and immature grain (G1) and weigh the grain size ((Th) and immature grain (G1), respectively, A control section (10) for controlling one or both of the hulling section (5) and the grain sorting section (7) for a driving time according to the measured value of the sample. This is the configuration of the selection device.

With this configuration, the present invention was able to obtain the following technical effects. Since one or both of the hulling section (5) or the grain sorting section (7) is driven for a driving time according to the weighed value of upper=h Even when there are fluctuations, the control unit +1 provides the necessary and sufficient work time for hulling and grain sorting.
Since it is automatically set by the control operation of 61, there is no waste in the operation of the hulling grain sorting device, and the device is operated efficiently and automatically with less labor.

Next, one embodiment of this invention will be explained. Fig. 1M shows the overall front view of the device, Fig. 2 shows the main process, and Fig. 3 shows the control block diagram. Husking consisting of, for example, rotating left and right hulling rolls that are automatically weighed and lifted onto the feeder (4) by a rice thrower (3) rotating in the direction of the arrow, and operated for a predetermined hulling time to be described later. The rice is hulled in section (5).

Then, the hulled rice is discharged from the rice husks to the machine by the wind sorting section (6).
) or (9) and rotates for a predetermined grain sorting time described later. Grain (G1
) leaks out, the immature grains (Q) are automatically weighed in the measuring section Q (I), and the immature grains (Q) that have finished weighing are transferred to the sample changeover valve ( 1
through which it is guided to the unripe sample outlet Oj. Also, when the rotation for the predetermined grain selection time is finished, the grain selection tube (8) or (
The valve 04) of 9) is opened (grain selection tube (9) in the illustrated example), and the sized grain (G2) remaining in the grain selection tube (8) or (9) flows into the measuring section 01, and enters the sample slot. It flows into the adjustment sample outlet (19) via the sample switching valve 02 at the sample switching valve 02.

The control unit f16) automatically controls the sudden switching operation of the sample switching valve (1) from the above-mentioned paddy weighing, and also controls the operation of the paddy measuring unit (2) for a driving time corresponding to the measured value of the paddy as a sample in the paddy measuring unit (2). It is configured to calculate and automatically control so as to drive either one of the sliding part (5) or the grain sorting part (force), or both of the rice hulling part (5) and the grain sorting part (force), and the above-mentioned measured value and The drive time is determined in advance through experiments, such as a direct proportional relationship or a quadratic proportional relationship, and then inputted into a program into the control unit 061.

Therefore, if the input amount of paddy is large and the weighing value is large,
The control section (1θ is the hulling section (
5), or the grain sorting section (7), or, if necessary, both the hulling section (5) and the grain sorting section (7). On the contrary, when the amount of paddy input is small and the measured value is small, a command is given to shorten the driving time.

In Fig. 1, the coded area is a switching valve for switching and feeding the polished rice that has finished the wind blade to either the sorting tube (8) or (9), and the valve (14 is for the grain type). Select tube (8), (
9) is configured to open and close in conjunction with the forward and reverse directions of rotation.

As shown in the flowchart of FIG. 2, the illustrated device is configured to print on paper the display of the date, code, etc. input at the time of acquisition, and the measurement data of the weight of immature grains and the weight of sized grains. has been done.

As the rice grain measuring section (2), the hulling section (5), the grain sorting section (7), etc., in addition to the illustrated example, various known ones can be used.
