Description

[Detailed Description of the Invention] The present invention relates to an automatic sorting control device in a rice sorting machine.

In other words, three troughs were built inside each
In a paddy sorting machine that is equipped with several pot-hole type rotary sorting cylinders, the rough sorting by the first sorting cylinder is carried out by the second sorting cylinder.
and the third sorting cylinder, where the second sorting cylinder separates and separates the small grains of grain into grains and removed rice, and the third sorting cylinder separates and sorts them into large grains of grain and paddy with branch stalks attached. To prevent other grains from getting mixed into the third sorting cylinder and reducing the sorting performance,
It is an object of the present invention to provide a system that can perform good automatic control to always maintain good sorting performance, ensure and perform good sorting of rice, and can be carried out suitably.

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

Reference numerals 2a, 2b, and 2c denote first, second, and third sorting cylinders, each of which is formed in a cylindrical shape with a large number of pot holes 3 on the inner peripheral surface. , 2c, troughs 1a, 1b, 1c each having a spiral conveyor 5 therein are constructed in the same manner as the conventional structure.

The first sorting drum 2a is provided with the raw rice as shown by the arrow A, so that the raw rice can be roughly sorted.
Trough 1a in first sorting drum 2a and second sorting drum 2b
The second sorting drum 2 is connected to the supply side of the second sorting drum 2 by a gutter 6.
The trough 1b is set up so that the small polished rice and the smashed rice can be separated and sorted by the second sorting drum 2b, and the small polished rice can be discharged from the discharge side of the second sorting drum 2b as shown by the arrow B, and the smashed rice can be discharged from the trough 1b as shown by the arrow C.
The supply side of the sorting drum 2c is connected by a trough 7 so that the third sorting drum 2c can separate and sort rice grains with attached stalks and containing straw etc. from large refined rice grains, and the third sorting drum 2c is configured so that rice grains with attached stalks and containing straw etc. come out from the discharge side of the third sorting drum 2c as indicated by arrow D, and large refined rice grains come out from the trough 1c as indicated by arrow E.

A motor M is rotatably mounted on a bracket 8 outside the first sorting cylinder 2a, and a male threaded rod 10 is screwed into a female threaded cylinder 9 which is rotated forward and backward by the motor M. The other end is connected to the trough 1a in the first sorting cylinder 2a, and the trough 1a is tilted while being rotated around the 5 axes of the spiral conveyor by means of a male threaded rod 10 that expands and contracts when the motor M rotates in the forward and backward directions. It is installed and configured so that the angle can be adjusted.

Further, 4a and 4b are flow meters, and the gutter 6
As shown in FIGS. 4 and 5, the plate body 11, which is inclined toward the inside of the gutter, is mounted on the support shaft 1.
2, and a weight 13 is fixed to the bent part on one end of the support shaft 12, and a potentiometer 14 on the other end of the support shaft 12 detects the rotation of the support shaft 12 to detect an increase or decrease in the flow rate. It is constructed in the same way as the conventional structure.

A control panel A is connected between the motor M and both flowmeters 4a and 4b, and as shown in FIG.
When the flow rate ratio is set to, for example, a ratio of 1:2, which is considered to be an appropriate ratio in normal cases, the detected values detected by the flowmeters 4a and 4b are compared and controlled by the comparator 16, and the When the ratio does not match the set ratio, a pulse signal is sent to the motor drive circuit 17, and the circuit 1
7, the motor M is configured to be able to send a forward rotation signal X for forward rotation of the motor M or a reverse rotation signal Y for reverse rotation to the motor M.

Therefore, during operation, each sorting cylinder rotates as shown by the arrow , and when the paddy, etc. engages with the pot hole 3, it is lifted upward and received into the trough as shown by the arrow , and is partitioned into the trough. The materials will remain in the sorting cylinder and will be separated and sorted.

During operation, raw materials are supplied to the first sorting cylinder 2a and rough sorting is performed, the second sorting cylinder 2b separates and sorts small refined rice and removed rice, and the third sorting cylinder 2c separates large refined rice and rice. The paddy with branches and stems attached will be separated and sorted, but if the ratio of the flow rate from the first to the second sorting cylinder and the flow rate from the first to the third sorting cylinder is the set ratio of 1:2. When sorting is performed normally, if the ratio of flow rate to the second sorting cylinder is higher than that of the first, rice grains with attached branches and stems may be mixed into the hulled rice, and the load on the second sorting cylinder increases, causing problems in dehulling. Removal performance will be reduced, and if the ratio of flow rate to the third sorting cylinder is too high than that of the first, removed rice will be mixed into the refined rice.

When the ratio of the respective flow rates is no longer the proper ratio, the detection values of both flowmeters 4a and 4b are compared and controlled, and the motor M starts rotating in either the forward or reverse direction. The trough 1a in 2a is adjusted to change the angle, and the first sorting cylinder 2a
This means that it is possible to adjust the coarse sorting in the second and third sorting cylinders, and the sorting can be adjusted by adjusting the flow rates to the second and third sorting cylinders to a set ratio.

In this way, the present invention has a first sorting barrel that roughly sorts the raw paddy into a mixture of small-grained refined paddy and dericed rice and a mixture of large-grained refined paddy and paddy with branch stems attached, each with a trough installed inside. , a second sorting barrel that sorts the mixture of small grained grains of grain and de-rice grains sorted by the first sorting barrel, and a third sorting barrel that sorts the mixture of large grains of grain and paddy with branch stalks attached are arranged in three stages. In the rice sorting machine, the trough in the first sorting cylinder that performs the above-mentioned rough sorting is installed so that its inclination angle can be changed freely by a motor, and the trough and the supply side of the second sorting cylinder are also connected to each other in the first sorting cylinder.
The discharge side of the sorting cylinder and the supply side of the third sorting cylinder are connected through a gutter, and a flow meter is installed in each gutter to detect an increase or decrease in the flow rate of each mixture using a potentiometer. Each detected value is compared and controlled by a comparator, and if the comparison value does not match the set ratio set on the setting device, the motor is rotated forward or reverse to automatically adjust the inclination angle of the trough to match the set ratio. Since the configuration is configured to change and adjust the flow rate, both flowmeters constantly detect the respective flow rates, and if they do not match the set ratio,
It is possible to adjust the inclination angle of the trough of the first sorting cylinder to an appropriate ratio, and it is possible to maintain good sorting performance through good automatic control, and to perform reliably good rice sorting. It has the advantage of being suitable for implementation.
