Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a huller for sorting a mixed rice of paddy and brown rice with a rotating sorting tube that has a hulling section and a large number of pot holes in the inner periphery. Can be used in sorting machines.

[Prior art] The grain sorting device is equipped with a husking section and a grain sorting device that rotates a rotary sorting tube, which has a large number of pot holes on its inner circumferential surface, around a horizontal axis to sort out mixed rice of paddy and brown rice. There is a rice hulling sorting machine that does this. As disclosed in Japanese Patent Application Laid-Open No. 61-242647, a rice grain value is provided in the rotary sorting section, and the grains to be sorted are detected by a layer H detector provided on the supply side of the rotary sorting cylinder. If the amount of grains to be sorted is large, the amount of grain supplied to the rotary sorting cylinder is controlled to decrease by reducing the supply amount of the paddy supply control valve on the hulling section side. When the amount of grain is small, increase the supply amount of the paddy supply control valve on the hulling section side to increase the amount of grain supplied to the rotary sorting tube, and optimize the amount of grains to be sorted in the rotary sorting tube. There are some people who are trying to do this.

[Problems to be Solved by the Invention] In this conventional device, when the layer thickness detector for detecting the amount of grains to be sorted in the rotary sorting cylinder is activated, the paddy supply 1n111 of the hulling section is activated.
Since the control valves operate in conjunction with each other, when the opening degree of the paddy supply control valve is increased in an attempt to increase work efficiency, the amount of grains to be sorted in the rotary sorting tube increases, and then the layer thickness detector detects the amount of grains to be sorted. When the amount of grain is detected, related control is performed to narrow the opening degree of the paddy supply control valve in the husking section, and if the operator desires high efficiency, there will be a shortage of supply at the husking section. If the opening degree of the paddy supply control valve is reduced in an attempt to maintain low work efficiency, the amount of grains to be sorted in the rotary sorting tube will decrease, and then the layer thickness detector will detect a large amount of grains to be sorted, and the grains will be removed. There was a problem in that related controls were performed to widen the opening degree of the paddy supply control valve in the phutting section, resulting in oversupply of paddy in the phutting section.

Therefore, the present invention solves these problems by controlling the layer thickness detector that detects the amount of grains to be sorted in the rotary sorting cylinder and the paddy supply control valve in the husking section in a related manner. Although it is a rice hulling sorting machine, it overcomes the drawbacks of conventional equipment by controlling the layer thickness detector of the rotating sorting cylinder and the hull supply control valve of the hulling section in a related manner according to the efficiency desired by the operator. This is what we are trying to resolve.

Hereinafter, it will be simply referred to as CPU. ) is a configuration that is manually operated.

Next, the control contents of C■)U 34 will be explained.

■When ON of the start switch (not shown) is inputted to the CPU 34, until the reduced grain detector 29 detects the reduced grain, in other words, the fallen rice in the husking section 1 is removed from the rotating sorting cylinder 1. 1 and until the grains after sorting are discharged from the sorting end side, a command signal that sets the paddy supply side flNr27 to a small opening, for example, a standard opening or a smaller opening, The signal is sent to the paddy supply relay 36 via the output interface 35, and the paddy supply control motor 30 rotates in the forward direction.

■Next, when the reduced grain detector 29 detects the reduction of grains, that is, the scraped rice from the husking section 1 is supplied to the rotary sorting cylinder 11 and starts flowing from the sorting start end, and starts flowing from the sorting end side. When the sorted grains are discharged from the rotary sorting cylinder 11 and the sorted grains are distributed over the entire area of the rotary sorting cylinder 11, automatic control is started based on the detection result of the layer thickness detector 24 as follows. That is, the detection information of the a0 layer thickness detector 24 is compared with the setting reference information, and if the detection information indicates that the grain layer thickness is greater than the reference information, a reverse drive signal is sent from the CPU 34 via the output interface 35.

Small is the standard for the initial opening degree of the paddy supply control valve 27 mentioned in (1) above. ), and in connection with this, the control reference information of the layer J1i potentiometer 26 is also switched to one of large, medium, and small. Therefore, the above automatic control (2) is controlled depending on whether the switched control reference information is large, medium, or small. In addition, this base f! The work efficiency setting means 32 for switching the function may be provided separately in the paddy supply potentiometer 28 and the layer thickness potentiometer 26, or the efficiency setting means 32 may be directly input to the CPU 34.

Next, the operation of the embodiment will be explained. When carrying out hulling work, paddy is supplied to the paddy hopper 2 and the rotating parts of the hulling and sorting machine are driven.Then, the paddy supplied from the paddy hopper 2 to the hulling section 1 is subjected to the hulling action. The fallen rice is wind-selected in the lower fallen rice wind selection path 4, and the rice husks are discharged from the dust exhaust pipe 6 to the outside of the machine. The mixed rice of brown rice and paddy is supplied dropwise to the sliding rice receiving trough 7, and is fed into the mixed rice grain lifting machine 8 through the mixed rice hopper 9 to the starting end side of the supply trough 14 above the rotary sorting cylinder 1. It is supplied to the supply side end of the rotary sorting tube 11 by the supply helix 13 in the supply trough 14 .

Next, the mixed rice is pumped through the pot hole of the rotary sorting cylinder 11 which is rotating clockwise in Fig. 2, and the brown rice with short grain length is pumped up high and falls into the finishing rice 1-16. , paddy with long grain length and some brown rice are pumped low, supplying 4i! It falls on 1i14 and is sorted. The unsorted mixed rice that has fallen into the feed gutter 14 is transferred to the feed gutter 14 by the feed helix 13.
From the conveyance terminal end thereof, the material is supplied again into the rotary sorting tube 11 and is re-sorted.

In addition, the rice that has fallen into the rice trough 16 is conveyed to the tithe rice flow lower tube 17 by the rice helix 15, passes through the grain machine 18, and is transferred to the rice receiver. Sakaki 19/＼During the process, the grains are sorted by a sorting wind, and taken out of the machine by a rice and yogurt machine 20.

The sorted paddy sent to the discharge side end of the rotary sorting cylinder 11 is
The paddy flows down to the lower paddy receiving trough 2, is fried by the paddy lifting machine 22, passes through the return paddy hopper 23, is returned to the husking section 1, and is again subjected to the husking action in the husking section 1. .

- The hulling and sorting work is carried out as described above, but under normal sorting conditions, during the sorting work in the rotary sorting circuit J1-1, the grains to be sorted in the rotary sorting f1"ii 11 are While detecting the amount of grains with the detection tool 24, the interface 35 outputs a control command signal from the CPU 34 in response to an increase or decrease in the amount of grains to be sorted.
6.37, the output is sent to the paddy supply control motor 30, and the opening degree of the paddy supply control valve 27 on the hulling section 1 side is adjusted to the closed side or the open side, and the grain to be sorted to the rotary sorting cylinder 11 is output. The amount of grain supplied is controlled to decrease or increase, and the hulling and sorting work is performed while maintaining the amount of grains to be sorted in the rotary sorting tube 11 appropriately.

When the start switch (not shown) is turned on at the start of the hulling sorting work, the paddy supply control valve 27 is set to a small opening degree from the start of the work until the reduced grain detector 29 detects reduced grains. A command signal to do this is output from the CPU 34 to the paddy supply control motor 30, and the paddy supply control valve 27 supplies paddy to the husking section 1 with a small opening degree, and a small amount of grain to be sorted is supplied to the rotary sorting tube 11. This prevents a large amount of grains to be sorted from being supplied to the rotary sorting cylinder [1] at the start of work, and can improve sorting accuracy. Furthermore, the switching of the paddy supply control valve 27 to automatic control is related to the fact that the reduced grain detector 29 detects the reduced grains returned to the husking section 1 from the sorting end side of the rotary sorting cylinder 11. Therefore, even if there are differences in the sorting flow state in the rotary sorting tube 11 depending on the moisture content or variety, it is possible to accurately know that the grains to be sorted have spread to the sorting end side of the rotary sorting tube 11, Sorting accuracy can be improved.

When the work efficiency setting means 32 is switched to the worker's desired work efficiency of high, medium, or low, the control reference information of the paddy supply control valve 27 built in the PU 34 is set to high, medium, or low. When the layer thickness potentiometer 26 is changed to either medium or small, and the control reference information of the layer thickness potentiometer 26 is also changed to large, medium, or small in connection with this, that is, when the efficiency is set to high, the fourth As shown in the figure, the layer thickness detector 24 detects the layer thickness based on the (a) position, and the paddy supply control valve 27 adjusts the amount of paddy supplied based on the (a) position. , and when the efficiency is set to low, the layer thickness detector 24 and the paddy supply control valve 2
7 are both controlled based on (b) position.

Therefore, the above-mentioned automatic control is controlled by either large, medium, or small of the control reference information that has been switched, and the layer thickness detector 24 and the layer thickness detector 24 based on the work efficiency desired by the operator are used. It is possible to perform related control with the paddy supply control valve 27 of the section 1.
