Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a multi-barrel rotary grain sorting machine with two horizontally installed rotary sorting barrels for sorting brown rice from mixed rice after hulling. This invention relates to a distribution device for distributing and supplying mixed rice into both sorting cylinders.

[Conventional technology]

A rotary sorting cylinder with a number of four-part recesses formed on its inner peripheral surface is installed horizontally, and one end of the sorting cylinder is configured as a supply side for mixed rice of brown rice and paddy, and the other end is configured as a paddy discharge side. On the other hand, a rotary grain sorting machine in which a brown rice receiving trough with an open top surface extending in the axial direction of the sorting barrel is disposed in the sorting barrel is disclosed in Japanese Patent Laid-Open No. 49-24746 as a prior art. etc., and if two of these rotary grain sorters are used,
It is easily understood that the sorting capacity is doubled.

[Problem that the invention seeks to solve]

However, in this rotary grain sorter, the mixed rice supplied into the sorting barrel is scraped up to a height created by the rotation of the sorting barrel, and then falls to the bottom, forming a fluidized bed while the rice is discharged from the discharge side. During the movement, the brown rice in the mixed rice gets stuck in the four parts and is lifted up to a relatively high position and then falls, while the paddy in the mixed rice moves to fall from a lower position than the brown rice. Taking advantage of this, the brown rice that falls from a high position is caught in the brown rice receiving trough and taken out. In this case, the height at which the brown rice and paddy fall is equal to the amount of mixed rice supplied into the sorting barrel It is approximately proportional to the thickness of the fluidized bed of mixed rice in the sorting barrel, and as the thickness of the fluidized bed becomes thicker, the amount of brown rice that enters the brown rice receiving trough will be lower than that for a given fluidized bed thickness. , when the thickness of the fluidized bed becomes thinner, the amount of paddy entering the brown rice receiving trough increases as the thickness of the fluidized bed becomes higher than in the case of a given fluidized bed thickness, so the thickness of the fluidized bed of mixed rice in the sorting barrel In other words, there is a predetermined appropriate value for the amount of mixed rice fed into the sorting cylinder.

Therefore, when using two rotary grain sorters as described above, in order to maintain high sorting performance, that is, sorting ability and sorting accuracy, it is necessary to It is necessary to adjust the amount of mixed rice to be equal, and if the amount of mixed rice fed to one sorting cylinder is large and the amount fed to the other sorting cylinder is small, the sorting performance of both sorting cylinders will decrease. I will do it.

The present invention makes it possible to extremely easily equalize the amount of mixed rice supplied to both sorting cylinders by operating a single distribution valve when two rotary grain sorters are used. At the same time, when the amount of mixed rice to be sorted is small, by operating the distribution valve, it is possible to simultaneously switch freely so that the sorting of the mixed rice is selectively performed only by one of the sorting cylinders, and further, In addition to the above, in the event that one or both of the sorting cylinders breaks down, the mixed rice can be discharged outside the machine without passing through the sorting cylinders.

[Means for solving problems]

Therefore, in the present invention, two rotary sorting cylinders each having a large number of four-part recesses formed on the inner circumferential surface are installed horizontally, and one end of the two sorting cylinders is placed on the supply side of the mixed rice of brown rice and paddy, and the other A multi-barrel type rotary grain type comprising an open-sided brown rice receiving trough extending in the axial direction of the sorting barrels in both sorting barrels, while each end is configured on the paddy discharge side. In the sorting machine, the distribution supply chute for distributing mixed rice to both the sorting cylinders is connected to the supply passage through which the mixed rice flows down at appropriate intervals in the flow direction, and the upstream of the redistribution supply chute is connected to the supply passage through which the mixed rice flows down. A distribution valve is provided at the lower edge of the portion where the distribution supply chute opens into the supply passage, and is provided with a distribution valve that opens and closes the opening and also opens and closes the supply passage at that location. A discharge port to the outside of the supply passage is provided at the portion where the distribution supply chute opens into the supply passage, and a discharge switching valve is provided to selectively open and close the discharge port and the downstream distribution supply chute. This is what I did.

[Action/effect of the invention]

In such a configuration, when the discharge port of the discharge switching valve in the supply passage through which the mixed rice flows is closed, the distribution valve of the upstream distribution supply chute is set to the upstream distribution supply chute of the distribution supply chute to both sorting cylinders. When the opening into the supply passage in the chute and the supply passage at that point are both opened, a portion of the mixed rice flowing down the supply passage enters the upstream distribution supply chute through the distribution valve. The remainder passes through this point into a downstream feed distribution chute from where it is distributed to feed the other sorting cylinder.

In this case, when the amount of mixed rice entering one sorting cylinder is larger than the amount of mixed rice entering the other sorting cylinder, by operating the distribution valve in the direction of closing the opening of the upstream distribution supply chute, It can be modified so that the amount of supply to one sorting cylinder is reduced and the amount of supply to the other sorting cylinder is increased, and
When the amount of mixed rice entering one sorting cylinder is smaller than the amount of mixed rice entering the other sorting cylinder, by moving the distribution valve in the direction of opening the opening of the upstream distribution supply chute, one sorting cylinder can be used. The amount of mixed rice supplied to both sorting cylinders can be made equal by adjusting the amount of mixed rice supplied to both sorting cylinders by operating the distribution valve. It's easy to do.

When the amount of mixed rice to be sorted is small, when the distribution valve is operated so that the opening of the 1-flow distribution supply chute is fully opened, all the mixed rice flowing down in the supply passage is transferred to the other sorting cylinder. Also, if the distribution valve is operated so that the supply passage at the opening is fully opened, all the mixed rice flowing down the supply passage will enter one sorting cylinder, so both sorting cylinders will be separated. By operating the distribution valve, it is possible to perform sorting work using only one of the cylinders, that is, to change a double-shell type having two sorting cylinders to a single-shell type using one of the sorting cylinders. It can be easily switched.

During the sorting operation using the two sorting cylinders, for example, if one of the sorting cylinders breaks down, the distribution valve is operated so that the opening of the upstream distribution supply chute is fully opened;
By operating the discharge switching valve to a position where both the downstream distribution supply chute and the discharge port are open, half of the mixed rice flowing down in the supply passage is supplied to the other sorting cylinder via the downstream distribution supply chute. On the other hand, since the remaining mixed rice will be discharged outside the machine from the discharge port, it is possible to continue the sorting operation using the other sorting cylinder. If the distribution valve malfunctions, half of the mixed rice flowing down in the supply passage can be transferred from the distribution valve to the upstream distribution supply by operating the discharge switching valve so that the downstream distribution supply chute is fully closed and the discharge port is fully open. While the rice is supplied to one sorting cylinder through the chute, the remaining mixed rice is discharged outside the machine from the discharge port, so it is possible to continue the sorting operation using one sorting cylinder. By operating the distribution valve so that the opening of the upstream distribution supply chute is fully open, and operating the discharge switching valve so that the downstream distribution supply chute is fully closed and the discharge port is fully open, the inside of the supply passage is All of the mixed rice flowing down can be discharged outside the machine.

Therefore, according to the present invention, the adjustment operation to equalize the amount of mixed rice supplied to the old sorting barrel in a multi-barrel type rotary grain sorter can be performed using one distribution valve, so the operation is extremely simple; When the amount of rice is small, or when one of the sorting barrels breaks down, the multi-barrel type can be arbitrarily switched to the single-barrel type by operating the distribution valve and discharge switching valve. This has the effect of being able to quickly and easily deal with changes in the amount of mixed rice, failure of either sorting cylinder, etc.
