[0097] A control method for a fully automatic intelligent rice milling device comprises the following steps:

[0098] Step 1: Paddy rice enters the rice bucket 1-1, the rice bucket test 4 is connected, press the start key 0 to connect, the stone removal specific gravity machine and the single hoist contactor 604 output, the specific gravity stone removal machine and the single-link elevator, i.e. the single hoist, are started, after a delay of 1 second, the rice bucket gate solenoid valve D0 is energized and the rice bucket gate cylinder 500 is inflated, driving the rice bucket gate 8-3 to open to the maximum, and the single hoist is loaded.

[0099] Grains slowly cover the grain screen 2-1, and the grain screen detector 5 senses the grains and is turned on, and the grain bucket gate air supply solenoid valve D1 outputs; the grain bucket gate air supply solenoid valve D1 is energized to exhaust; the grain bucket gate cylinder 500 exhausts, and the tension spring 8-2 of the grain bucket gate 8-3 presses the grain bucket gate 8-3 to the limit position, the opening of the grain bucket gate 8-3 is reduced, and the feeding speed is slowed down.

[0100] On the contrary, when the grain screen 5 cannot sense the grain, the grain bucket gate air supply solenoid valve D1 is disconnected; the grain bucket gate air supply solenoid valve D1 loses power and air supply, the grain bucket gate cylinder 500 is inflated, the cylinder force overcomes the spring pressure, and the grain bucket gate 8-3 is opened to the maximum; the feeding speed is accelerated, and this cycle is repeated to ensure that different materials can be fed at a limited speed; ensuring that the next step works normally.

[0101] Step 2: If there are too many grain impurities and the material cannot be loaded, after the single-lift machine has worked for 30 seconds, the grain screen 5 cannot detect any material, the whole machine will stop working, the output group output will be displayed, and the main controller PLC system will show that the single-lift machine cannot load the material.

[0102] If the single elevator feeds too fast, the ridge grain bucket 3-1 exceeds half a bucket, and the ridge grain bucket tester 11 is connected and connected for more than 90 seconds, it means that the grain bucket 1-1 is too full, the grain bucket gate solenoid valve D0 and the grain bucket gate air supply solenoid valve D1 are disconnected, and the grain bucket gate 8-3 is closed. After a delay of one second, the stone removal specific gravity machine and the single elevator contactor 604 are disconnected, and the single elevator stops until the ridge grain bucket tester 11 is disconnected, and the single elevator resumes work and feeding; when the grain bucket tester 11 is disconnected, it means that the grain bucket material has been loaded, and the grain bucket gate is closed after ten seconds, and after another 40 seconds, the single elevator stops working.

[0103] During the operation of the single-lift machine, if the material on the single-lift machine is too fast, the rice screen 2-1 is full, the overflow position detector 108 is turned on, and the output group output is displayed. Capacitor sensors are installed at the four positions of the rice screen, the bottom of the rice husker, the small bucket on the separation screen, and the small plate under the wind-lifted rice. The output ends of the capacitor sensors are connected in parallel with the overflow position detector 108, and the whole machine stops working when it overflows.

[0104] Step 3: After the single lift has worked for ten seconds, the double lift contactor 603 outputs, the double elevator, i.e., the double lift, starts, and the rice is transported to the ridge bucket 3-1; the material in the ridge bucket 3-1 reaches the half bucket, the ridge bucket test 11 is connected, the ridge machine contactor 601 outputs, the rice husker starts, and after a delay of one second, the ridge gate solenoid valve D8 outputs, the rice husker gate opens, and the rice husker starts. At the same time, the separation screen contactor 606 outputs, and the gravity separation screen, i.e., the gravity screen 5-1, starts; the main controller PLC starts timing and charging, the display output group outputs, the crusher contactor 602 outputs, and the crusher starts.

[0105] The grinder current detector monitors the working current of the grinder. When it exceeds the rated value, the grinder current measurement 107 outputs, the ridge gate solenoid valve D8 is disconnected, and the rice husking gate is closed. After the grinder current drops back to the rated value, the ridge gate solenoid valve D8 outputs; the rice husking gate is opened, and the rice is husked again to ensure the safety of the grinder.

[0106] Step 4: As the grain-rough mixture gradually covers the separation screen, the right position sensor 6 of the separation screen senses the grain-rough mixture, and the right position sensor 6 of the separation screen is turned on. Subsequently, the front position sensor 7 of the separation screen senses the grain-rough mixture, and the front position sensor 7 of the separation screen is turned on. Ten seconds later, the lower rough gate solenoid valve D4 outputs, the lower rough gate solenoid valve D4 is energized, and the lower rough gate 5-4 is opened. Ten seconds later, the center-sealed solenoid valve D12A end is turned on, the center-sealed solenoid valve D12A end is energized and outputs, the separation adjustment plate 5-2 moves rightward to the midpoint, the center position sensor 101 of the separation adjustment plate is turned on, the center-sealed solenoid valve D12A end is disconnected, and the separation adjustment plate 5-2 stops at the middle position. Ten seconds later, the center-sealed solenoid valve D12A end outputs again, and the separation adjustment plate 5-2 continues to move rightward to the rightmost end. Ten seconds later, the center-sealed solenoid valve D12A end is disconnected.

[0107] If the right position sensor 6 of the separation screen cannot sense the rice-rough mixture 17 seconds after the rice husker gate is opened, the whole machine will stop working, the output group output will be displayed, and the main controller PLC system will display a rice husker failure.

[0108] During normal operation of the machine, if the right position measurement 6 of the separation screen senses the grain-rough mixture from normal to no longer sense the grain-rough mixture, and there is grain in the grain bucket 1-1, and the single lift is working, the center-sealed solenoid valve D12B end will output, the center-sealed solenoid valve D12B end will be energized, the separation adjustment plate 5-2 will move left to the leftmost end, the separation adjustment plate small position measurement 1 will be connected, and the center-sealed solenoid valve D12B end will be disconnected; wait until the gravity screen 5-1 is full again, the right position measurement 6 of the separation screen will sense the grain-rough mixture again, 2 seconds later, the center-sealed solenoid valve D12A end will be energized and output, the separation adjustment plate 5-2 will move right to the rightmost end, and 10 seconds later, the center-sealed solenoid valve D12A end will be disconnected.

[0109] After the grain bucket material is loaded, the material on the gravity screen 5-1 gradually decreases, and the separation screen right position sensor 6 cannot sense the material. After 2 seconds, the center-sealed solenoid valve D12B end outputs, the center-sealed solenoid valve D12B end is energized, the separation adjustment plate 5-2 moves left to the midpoint, the separation adjustment plate center position sensor 101 is connected, the center-sealed solenoid valve D12B end is disconnected, and the separation adjustment plate 5-2 stops in the middle position; after 10 seconds, the center-sealed solenoid valve D12B end outputs, the center-sealed solenoid valve D12B end is energized, the separation adjustment plate 5-2 moves left to the left end, the separation adjustment plate small position sensor 1 is connected, the separation adjustment plate small position sensor 1 is connected, and the center-sealed solenoid valve D12B end is disconnected.

[0110] Step 5: As the material on the gravity screen 5-1 decreases, the front position sensor 7 of the separation screen cannot sense the material and the separation screen front position sensor 7 is disconnected. After 2 seconds, the lower rough gate solenoid valve D4 is disconnected and the lower rough gate solenoid valve D4 loses power and the lower rough gate is closed. At the same time, the ridge gate solenoid valve D2 is output and the ridge gate solenoid valve D2 is energized. The ridge gate is opened to the straight cage position and the ridge gate straight ridge position sensor 2 is connected. After 40 seconds of straight ridge, the tail gate solenoid valve D3 is output and the tail gate solenoid valve D3 is energized. The tail valve is opened and the tail material is lowered. After 12 seconds, the tail gate solenoid valve D3 is disconnected and the tail valve is closed. At the same time, the ridge gate solenoid valve D2 is disconnected and the ridge gate is closed to its original position. The separation screen contactor 606 is disconnected and the separation screen is shut down.

[0111] During the rice husking process, if the bottom of the rice husking machine is blocked, the small bucket on the separation screen is blocked, and the overflow position detector 108 is connected, the whole machine will stop working, and the display output group will output. Capacitor sensors are installed at the four positions of the rice screen, the bottom of the rice husking machine, the small bucket on the separation screen, and the small plate under the wind-lifted rice. The output end of the capacitor sensor is connected in parallel with the overflow position detector 108, and the whole machine will stop working if it overflows.

[0112] Step 6: After the lower brown rice gate is opened, the brown rice slowly fills the rice machine bucket; the bottom position sensor 8 of the rice machine bucket senses the brown rice first, and the bottom position sensor 8 of the rice machine bucket is connected; if the bottom position sensor 8 of the rice machine bucket cannot sense the brown rice 15 seconds after the lower brown rice gate is opened, the whole machine will stop working, the output group output will be displayed, and the system will show that the brown rice cannot be lowered. When the middle position sensor 15 of the rice machine bucket senses the brown rice, the middle position sensor 15 of the rice machine bucket is connected.

[0113] 6 seconds after being connected, the rice milling machine contactor 600 outputs, the rice milling machine starts, after a delay of 2 seconds, the rice milling machine gate solenoid valve D5 outputs, the rice milling machine gate solenoid valve D5 is energized, the rice milling machine gate is opened, and the rice milling starts. The rice milling condition is adjusted by the rice milling machine current. When the rice milling machine current is greater than the rated value, the current detector outputs, the rice milling machine current measurement 104 is turned on, the rice milling machine pressing plate 513 outputs, that is, a pulse output, the rice milling machine pressing plate motor reverses, and the rice milling machine pressing plate 513 is pulled until the rice milling machine current is reduced to the rated value.

[0114] When the brown rice in the rice machine bucket is milled, the rice machine bucket bottom position sensor 8 cannot sense brown rice for 4 seconds, the rice machine press plate 607 outputs a pulse output, the rice machine press plate motor rotates forward, and the rice machine press plate is relaxed; when the tailings are completed and the tailings gate is closed, the rice machine bucket bottom position sensor 8 cannot sense brown rice for 4 seconds, the rice machine gate is closed, and after another 8 seconds, the shutdown program is entered to shut down the rice mill, crusher, rice husker, double lifting machine, and rice husker gate, and the main controller PLC system displays the processing cost of this time, and the rice milling process is completed.

[0115] During the rice milling process, when husking rice, if the rice milling is too slow, the rice machine bucket center position meter 15 continuously senses brown rice for 60 seconds, then the lower brown rice gate is temporarily closed until the rice machine bucket center position meter 15 no longer senses brown rice;

[0116] Step 7: After the white rice comes out of the rice mill, it is lifted by the wind rice lifting machine to the broken rice screen and then to the rice hopper; the wind rice lifting machine starts and stops with the rice mill, and the broken rice screen starts with the rice mill and shuts down 40 seconds later than the rice mill.

[0117] The technical conditions of the NZJ-15 / 15-III ridge-rolling combined rice mill available on the market are as follows:

[0118] 1. Main technical parameters and performance specifications:

[0119] Type: Rubber sand roller machine

[0120] Productivity: 700-1000kg / h paddy, rice yield: third-grade paddy (depending on the quality of the paddy) 68%-72% (standard 1 meter), overall dimensions: (length×width×height) 3180×2200×2760mm, machine weight: 900kg (fine bran type 980kg), equipped with power: total power 16.37-18.37KW (fine bran type 21.78KW), including: 11 or 15KW-4 poles (fine sugar type 18.5 or 22KW-4 poles), 0.75KW-2 poles, 0.37KW-4 poles (1 set each), 0.75KW- 4 poles and 3 units, the speed of each part: (see the transmission pulley speed and V-belt installation diagram for details), rice sieve: 1132r / min, stone remover: 617r / min, double elevator: 218r / min, rice machine: 1400r / min, rice crusher: 370r / min, high pressure fine bran fan: 3509r / min, stone remover fan: 2830r / min, single elevator: 231r / min, large sugar fan: 2806r / min, rough rice gravity screen: 258r / min, crusher (fine bran type) 4420r / min.

[0121] 2. Equipment structure and process flow:

[0122] This machine uses a single elevator to lift the rice to the impurity and stone remover to remove ash, impurities and stones, and then sends the material to the rice separator and gravity rice-bran separation screen through a double elevator to separate the large bran and clean brown rice at the same time. The large bran is discharged (or crushed) by the large bran fan, and the clean brown rice is sent to the rice mill to be processed into white rice, and the broken rice is further screened and separated by the broken rice screen to meet the requirements of finished rice.

[0123] 3. Production operation:

[0124] Before starting the machine, you should first check whether the base bolts and other fasteners are tightened, whether the pressure door of the rice mill outlet and various adjustments and transmission mechanisms are flexible and reliable, manually pull the rice mill main shaft to rotate, check whether there are any forgotten production equipment that affects the operation of the machine, whether the gear box and bearing parts are lubricated with lubricating oil and grease, unscrew the observation hole cover on the side wall of the rubber roll, and check the rolling distance between the two rolls. The value can be determined according to the actual situation of the raw grains being processed. Generally, it is adjusted to 1-1.2mm when processing japonica rice; it is adjusted to 0.8-1mm when processing cane rice. Whether the rolling distance is appropriate can be identified by the shelling rate (generally it should be above 85-90%).

[0125] After doing the above work, you can test run the empty machine for 20 minutes. After everything is normal, you can add materials for production. During processing, the large bran separator throwing plate, air duct box, and large bran fan suction wind adjustment door should be appropriately adjusted according to the user's choice of machine type: large bran separation type or fine bran type (Note: wind adjustment depends on the air duct box label). Whether the adjustment is correct should be observed on the large bran content on the gravity screen plate, and there should be a small amount of large bran. Too much large bran content means that the suction force is too weak, which will affect the rice separation effect. Very little large bran content means that the suction force is too strong, which will affect the rice output rate. The fine bran type should use the up and down movement of the gate connected to the throwing plate and the suction wind adjustment door to coordinate and adjust to achieve the best effect (Note: It is best to remove the gate connected to the throwing plate or move it up to the position before using the large bran separation model). The gravity screen should be adjusted to uniformly feed each layer from the beginning of the elevator feeding to ensure that the grain and rough separation material of each layer is discharged at the same position, which is convenient for accurate grain and rough separation and tailings. The double elevator discharge nozzle has four outlets, namely the rice discharge inlet, the rice-rough mixture feed inlet to the gravity screen, the tailings return inlet, and the tailings brown rice into the rice milling inlet. Users should operate correctly according to the instructions on the label on the double elevator discharge pipe.

[0126] When the rice machine is milling rice, two-thirds of the brown rice should be put into the brown rice hopper first, and then the feed door should be pulled to start feeding and processing (Note: this is mainly to make up for the time difference when the brown rice gravity screen collects the tail material, so as to reduce the idling time and reduce the broken rice rate), and the load situation indicated by the ammeter of the main motor should be combined with the processing speed and white rice.

[0127] Accuracy (Note: The correct current reading of the ammeter: 11 kW is 21A, 15 kW is 29A, 18.5 kW is 36A, 22 kW is 42A. Exceeding the rated current means that overload operation will burn out the motor). To adjust the output and effect of the rice milling machine's rough rice gravity screen, the adjustment screw on the large eccentric bearing seat at the bottom of the screen can be extended and shortened to adjust the height of the rear bracket. Raising or extending the screw will reduce the output, but will improve the effect of grain separation. Lowering or shortening the screw will increase the output, but will affect the effect of rough rice separation. Users can make slight adjustments based on the position adjusted by the installation and commissioning personnel and the actual processing conditions. To achieve the best effect. Our company recommends that users choose a white rice wind-transported crushing unit or a broken rice screen to reduce the rice bran powder rate and broken rice rate. Users of fine bran type should choose dust removal cylinders and fan shut-off fans according to the surrounding environment of the rice mill to reduce environmental dust. Rice bran (or crushed mixed bran) should be collected in time during processing to prevent the fine bran fan and crusher from blocking. The impurity and stone removal machine must ensure that the machine base is stable, level front and back, left and right, and the feed size of the elevator should be uniform to ensure the impurity and stone removal effect. The height of the tail stone discharge port and the bottom eccentric screw should be adjusted according to the stone discharge situation. Adjusting it too high will affect the stone removal effect, and adjusting it too low will cause grains to come out.

[0128] The working principle of this utility model:

[0129] Pour the rice into the rice bucket 1-1, the rice bucket tester 4 is connected, press the start key 0 to connect, the stone removal specific gravity machine and the single elevator contactor 604 output, the specific gravity stone removal machine and the single elevator (hereinafter referred to as the single elevator) start, after a delay of 1 second, the rice bucket gate solenoid valve D0 is energized and output, the rice bucket gate cylinder 500 is inflated, driving the rice bucket gate 8-3 to open to the maximum, and the single elevator is loaded. Grains slowly fill the grain screen 2-1, the grain screen tester 5 senses the grain connection, the grain screen tester 5 is connected, and the grain bucket gate air supply solenoid valve D1 outputs. The grain bucket gate air supply solenoid valve D1 is energized to exhaust. The grain bucket gate cylinder 500 exhausts, and the tension spring 8-2 of the grain bucket gate 8-3 presses the grain bucket gate 8-3 to the limit position, the opening of the grain bucket gate 8-3 is reduced, and the loading speed is slowed down. On the contrary, after the grain screen tester 5 cannot sense the grain, the grain bucket gate air supply solenoid valve D1 is disconnected. The air supply solenoid valve D1 of the grain bucket gate loses power and the air supply is restored. The air cylinder 500 of the grain bucket gate is inflated, and the cylinder force overcomes the spring pressure to open the grain bucket gate 8-3 to the maximum. The feeding speed is accelerated, and the cycle is repeated to ensure that different materials can be fed at a limited speed, ensuring that the next step works normally.

[0130] If there are too many grains and debris and the material cannot be loaded, after the single-lift machine has been working for 30 seconds, the grain screen 5 cannot detect any material, the whole machine will stop working, the output group output will be displayed, and the main controller PLC will show that the single-lift machine cannot load the material.

[0131] If the single elevator feeds too fast, the ridge bucket 3-1 exceeds half a bucket, and the ridge bucket sensor 11 is connected and connected for more than 90 seconds, it means that the grain bucket 1-1 is too full, the grain bucket gate solenoid valve D0 and the grain bucket gate air supply solenoid valve D1 are disconnected, and the grain bucket gate 8-3 is closed. After a delay of one second, the stone removal specific gravity machine and the single elevator contactor 604 are disconnected, and the single elevator stops until the ridge bucket sensor 11 is disconnected, and the single elevator resumes work and feeding.

[0132] When the grain bucket test 11 is disconnected, it means that the material in the grain bucket has been loaded. After ten seconds, the grain bucket gate is closed. After another 40 seconds, the single hoist stops working.

[0133] During the operation of the single-lift machine, if the material on the single-lift machine is too fast, the rice screen 2-1 is full, the overflow position measurement 108 is turned on, the output group output is displayed, and the main controller PLC displays that the rice screen, the bottom of the rice husker, the small bucket on the separation screen, and the small plate under the wind-lifted rice are full. Capacitor sensors are installed at these four positions respectively, and the output ends are connected in parallel with the overflow position measurement 108, and the whole machine stops working.

[0134] After the single elevator has worked for ten seconds, the double elevator contactor 603 outputs, the double elevator (hereinafter referred to as the double elevator) starts, and the rice is transported to the ridge bucket 3-1. The material in the ridge bucket 3-1 reaches the half bucket, the ridge bucket test 11 is connected, the ridge machine contactor 601 outputs, the rice husker starts, and after a delay of one second, the ridge gate solenoid valve D8 outputs, the husker gate opens, and the husker starts. At the same time, the separation screen contactor 606 outputs, and the gravity separation screen (hereinafter referred to as the gravity screen 5-1) starts. The controller PLC starts timing and charging, the display output group outputs, slow flash charging, the crusher contactor 602 outputs, and the crusher starts the crusher independent device. The crusher current detector monitors the working current of the crusher. When it exceeds the rated value, the crusher current test 107 outputs, the ridge gate solenoid valve D8 is disconnected, and the husker gate is closed. After the crusher current drops back to the rated value, the ridge gate solenoid valve D8 outputs. Open the rice husking gate, husking the rice again, and ensuring the safety of the crusher.

[0135] As the grain-rough mixture gradually covers the separation screen, the right position sensor 6 of the separation screen senses the grain-rough mixture and the right position sensor 6 of the separation screen is turned on. Then the front position sensor 7 of the separation screen senses the grain-rough mixture and the front position sensor 7 of the separation screen is turned on. Ten seconds later, the lower rough gate solenoid valve D4 outputs and the lower rough gate solenoid valve D4 is energized, and the lower rough gate 5-4 is opened. Ten seconds later, the center-sealed solenoid valve D12A end is turned on, the center-sealed solenoid valve D12A end is energized and outputs, and the separation adjustment plate 5-2 moves rightward to the midpoint, the center position sensor 101 of the separation adjustment plate is turned on, the center-sealed solenoid valve D12A end is disconnected, and the separation adjustment plate 5-2 stops in the middle position. Ten seconds later, the center-sealed solenoid valve D12A end outputs again, and the separation adjustment plate 5-2 continues to move rightward to the rightmost end. Ten seconds later, the center-sealed solenoid valve D12A end is disconnected.

[0136] If the right position sensor 6 of the separation screen cannot sense the rice-rough mixture 17 seconds after the rice husker gate is opened, the whole machine will stop working, the output group output will be displayed, and the main controller PLC will display the rice husker failure.

[0137] During normal operation of the machine, if the right position measurement 6 of the separation screen changes from normal induction to the grain-rough mixture to induction, and there is grain in the grain bucket 1-1, and the single lift is working, the middle-sealed solenoid valve D12B end outputs, the middle-sealed solenoid valve D12B end is energized, the separation adjustment plate 5-2 moves left to the leftmost end, the separation adjustment plate small position measurement 1 is connected, and the middle-sealed solenoid valve D12B end is disconnected. When the gravity screen 5-1 is full again, the right position measurement 6 of the separation screen senses the grain-rough mixture again, and after 2 seconds, the middle-sealed solenoid valve D12A end is energized and output, and the separation adjustment plate 5-2 moves right to the rightmost end. After 10 seconds, the middle-sealed solenoid valve D12A end is disconnected.

[0138] After the grain bucket is loaded with materials, the materials on the gravity screen 5-1 gradually decrease, and the separation screen right position measurement 6 cannot sense the materials. After 2 seconds, the center-sealed solenoid valve D12B end outputs, the center-sealed solenoid valve D12B end is energized, the separation adjustment plate 5-2 moves left to the midpoint, the separation adjustment plate mid-position measurement 101 is connected, the center-sealed solenoid valve D12B end is disconnected, and the separation adjustment plate 5-2 stops at the midpoint. After 10 seconds, the center-sealed solenoid valve D12B end outputs, the center-sealed solenoid valve D12B end is energized, the separation adjustment plate 5-2 moves left to the left end, the separation adjustment plate small position measurement 1 is connected, the separation adjustment plate small position measurement 1 is connected, and the center-sealed solenoid valve D12B end is disconnected.

[0139] As the material on the gravity screen 5-1 decreases, the front position sensor 7 of the separation screen cannot sense the material and is disconnected. After 2 seconds, the lower rough gate solenoid valve D4 is disconnected and the lower rough gate solenoid valve D4 loses power and the lower rough gate is closed. At the same time, the ridge gate solenoid valve D2 is output and the ridge gate solenoid valve D2 is energized, the ridge gate is opened to the straight cage position, and the ridge gate straight ridge position sensor 2 is connected. After 40 seconds of straight ridge, the tail gate solenoid valve D3 is output and the tail gate solenoid valve D3 is energized, the tail valve is opened, and the tail material is lowered. After 12 seconds, the tail gate solenoid valve D3 is disconnected and the tail valve is closed. At the same time, the ridge gate solenoid valve D2 is disconnected and the ridge gate is closed to its original position. The separation screen contactor 606 is disconnected and the separation screen is shut down.

[0140] During the rice husking process, if the bottom of the rice husking machine is blocked, the small bucket on the separation screen is blocked, and the overflow position sensor 108 is connected, the whole machine will stop working, the output group will be displayed, and the main controller PLC will display that the rice screen, the bottom of the rice husking machine, the small bucket on the separation screen, and the small plate under the wind-lifted rice are overflowing.

[0141] After the lower brown rice gate is opened, the brown rice slowly fills the rice machine bucket. The bottom position sensor 8 of the rice machine bucket senses the brown rice first, and the bottom position sensor 8 of the rice machine bucket is connected. If the bottom position sensor 8 of the rice machine bucket cannot sense the brown rice 15 seconds after the lower brown rice gate is opened, the whole machine will stop working, the output group will output, and the main controller PLC will show that the brown rice cannot be lowered. When the middle position sensor 15 of the rice machine bucket senses the brown rice, the middle position sensor 15 of the rice machine bucket is connected.

[0142] After 6 seconds of connection, the rice milling machine contactor 600 outputs, and the rice milling machine starts. After a delay of 2 seconds, the rice milling machine gate solenoid valve D5 outputs, the rice milling machine gate solenoid valve D5 is energized, the rice milling machine gate is opened, and the rice milling starts. The rice milling condition is adjusted by the rice milling machine current. When the rice milling machine current is greater than the rated value, the current detector outputs, the rice milling machine current measurement 104 is connected, the rice milling machine pressing plate 513 outputs a pulse output, the rice milling machine pressing plate motor reverses, and the rice milling machine pressing plate 513 is pulled until the rice milling machine current is reduced to the rated value. When the rice milling machine bucket finishes the brown rice milling, the rice milling machine bucket bottom position measurement 8 can no longer sense the brown rice for 4 seconds, and the rice milling machine pressing plate 607 outputs a pulse output, the rice milling machine pressing plate motor rotates forward, and the rice milling machine pressing plate is released. When the tailings are finished and the tailings gate is closed, the rice machine gate is closed after the rice machine bottom position sensor 8 senses no brown rice for 4 seconds. After another 8 seconds, the shutdown procedure is entered to shut down the rice mill, crusher, husker, double lift machine and husker gate. The processing cost is displayed and the rice milling process is completed.

[0143] During the rice milling process, when husking rice, if the rice milling is too slow, the center position meter 15 of the rice machine bucket continuously senses brown rice for 60 seconds, and the lower brown rice gate is temporarily closed until the center position meter 15 of the rice machine bucket no longer senses brown rice.

[0144] After the white rice comes out of the rice mill, it is lifted by the wind rice lifter to the broken rice screen and then to the rice hopper. The wind rice lifter starts and stops with the rice mill, and the broken rice screen starts with the rice mill and shuts down 40 seconds later than the rice mill.

[0145] This system is modified based on the original (NZJ-15 / 15-III) combined rice mill, with a series of sensors and controllers added. The programmable master controller PLC detects the rice milling conditions according to the sensors, controls the coordinated work of various components, and achieves the effect of fully automatic intelligent rice milling. The rice milling operator only needs to start with one button to complete the entire rice milling process, which greatly reduces the labor intensity of rice milling operations that constantly change rice varieties. It provides the necessary conditions for adding coin-operated and code-scanning self-service rice milling in the future.

[0146] This system is centered on the programmable master controller PLC, which includes: the first controller PLC1, model: KV-40DT) and the additional extended second controller PLC2, model: KV-16DT. It uses photoelectric, capacitive current detection and other sensors to collect the working conditions of various devices in the rice milling process. After analysis and processing by the master controller PLC, it controls the external intermediate relay and the operation of various solenoid valves, AC contactors, cylinders and motors. This system adopts a time-based billing design, which makes the calculation simple and intuitive.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
