Description

[Detailed Description of the Invention] The present invention relates to a switching and discharging device when a grain sorting board is clogged in an oscillating grain sorter.

In other words, a large number of grain sorting plates with rough surfaces are stacked and tilted so as to be able to swing freely, and the lower part of the outlet side of each grain sorting plate is partitioned with a partition plate and equipped with a brown rice outlet, a mixed rice outlet, and a paddy outlet, respectively. Conventionally, in an oscillating grain sorting machine that is constructed by installing multiple grain sorters, only the topmost grain sorting plate could be seen from the outside, and if the lower grain sorting plate was clogged and the grain flow was poor. In some cases, it was not possible to confirm this, and there were drawbacks such as poor sorting and paddy contamination at the outlet side of the brown rice.

The present invention solves these drawbacks; it can alert you with an alarm even if any grain sorting plate is clogged and result in poor sorting, and it can also be switched to prevent paddy from entering the brown rice outlet. The present invention provides a simple structure that can be easily implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of the entire oscillating grain sorting machine, in which a large number of grain sorting plates 1 each having a rough surface on the upper surface are tilted in the vertical direction Y and the horizontal direction X, respectively, and overlapped vertically.
The lower part of all grain sorting boards 1 is constructed so as to be supported by each swing support rod 10 from the frame 9 side, and each grain sorting board 1 is installed so as to be able to swing in the lateral direction X in the same manner as the conventional structure. and configure.

In addition, an upright supply port 6 is formed at the upper end of the longitudinal direction Y inclination of each grain sorting board 1, and a tank 12 is connected to the outside of each supply port 6, and a tank 12 is connected to the bottom of each supply port 6. Receiving plates 13 are installed in short lengths inward of the tank 12, and brown rice and mixed rice are partitioned inward by a gutter frame plate 14, which is visible at the upper end of each grain sorting plate 1 on the vertical Y slope. A gutter frame board in which a partition plate 2 and a partition plate 2a for separating mixed rice and paddy are erected so that they can be moved laterally with knobs 15 and 16, respectively, and partitioned by the partition plate 2. 14
There is a brown rice outlet 3 on the lower side of one end, and partition plates 2 and 3 on both sides.
A mixed rice outlet 4 is installed below the center side of the gutter frame plate 14, which is the lower part between the two, and a paddy outlet 5 is installed below the other end side of the gutter frame plate 14 partitioned by the partition plate 2a. They are installed so that they can flow out from the brown rice outlet 3 to the take-out side, from the mixed rice outlet 4 to the tank 12 side, and from the paddy outlet 5 to the hulling machine side, and are constructed similarly to the conventional structure.

A capacitance type switch 7 is installed on the upper surface of each receiving plate 13 near the front side of each supply port 6, and is operated depending on whether or not it comes into contact with grains. A switching guide valve 8 is rotatably mounted on a support shaft 17 between the outlet 3 and the mixed rice exit 4, and a solenoid body 19 is connected to the tip of an arm 18 fixed to the outer end of the support shaft 17. The retracting operating rod 20 is connected, and when one of the supply ports 6 is clogged and the flow rate of grains decreases, the switch 7 in that part is activated to operate the solenoid body 19 and to open the switching guide valve 8. Each switch 7 is connected to the solenoid body 19 through the control circuit of the control panel 21.
When the switch 7 is activated, a buzzer or a lamp type alarm 11 can be activated.

Therefore, during work, the mixed rice supplied to the tank 12 is transferred from the top of each receiving plate 13 to the respective supply ports 6.
The grains flow through the grain selection plates 1 through the grain selection plates 1, and are sorted in the same manner as conventional methods on the grain selection plates 1 that are swung in the horizontal direction X. Brown rice is discharged from one end, mixed rice is discharged from the middle, and paddy is discharged from the other end. They fall through the space partitioned by partition plates 2 and 2a and flow out from brown rice outlet 3, mixed rice outlet 4, and paddy outlet 5, respectively. I will do it.

In this state, the switching guide valve 8 is in an upright state and is in a state of partitioning off the two outlets 3 and 4.

By the way, if any of the supply ports 6 is clogged with foreign matter, branches, etc., the flow of grains will be poor on the receiving plate 13 in that area, and the switch 7 in that area will detect this condition. , the solenoid body 19 is immediately activated to rotate the switching guide valve 8 to the upper side of the brown rice outlet 3 as shown by the imaginary line in FIG. Even if the paddy flowing into the side is dropped to the brown rice outlet 3 side, it will be guided by the switching guide valve 8 and flowed out to the mixed rice outlet 4 side.
Paddy will no longer be mixed into the brown rice that is taken out.

In that case, when the switch 7 is activated as described above, the alarm 11 can be immediately activated to give an alarm.

In this way, the present invention constructs a grain selection plate having a rough surface at an angle so that it can swing freely, and partitions the lower part of the exit side of the grain selection plate with a partition plate to provide a brown rice outlet, a mixed rice outlet, and a paddy outlet, respectively. In the oscillating grain sorting machine, a switch for detecting clogging is installed near the supply port on the upper side of the slope of the grain selection plate, and a switch for detecting clogging is installed between the brown rice outlet and the mixed rice outlet. The switch is equipped with a switching guide valve that switches when the switch is activated, and the alarm is activated when the switch is activated. It has the feature that it can be switched well so that the rice does not enter the brown rice side and is not taken out, and that it can be suitably implemented with a simple structure.
