Specifically, the first silo 1 is designed with a bypass overflow port connected to the upper feed port of the first silo 1. After a part of the sample enters the moisture detection silo 17 from the bypass overflow port, the sample is tested for moisture by the moisture meter 18 to obtain the moisture content. After the moisture detection is completed, the controller controls the discharge door 19 to open, so that the sample that has completed the moisture detection flows back into the first silo 1. Through this structural design, the moisture detection and subsequent detection can be carried out simultaneously, which shortens the time of the entire detection process and improves the detection efficiency.

Specifically, the first valve 20 is a valve comprising at least two interfaces, preferably a three-way valve, which can be electric or pneumatic. After the first metering scale 2 quantitatively weighs the preset weight of the sample, the controller controls the first valve 20 to switch to the feed port of the cleaning screen 3, and the weighed weight is transported to the cleaning screen 3 for impurity removal. When the sample in the first metering scale 2 is discharged, the controller controls the first valve 20 to switch to the sample bag 21, and the remaining sample in the first silo 1 and the sample in the moisture detection silo 17 are transported to the sample bag 21 for storage.

Among them, the specific structures of the rice husker 22 and the rice milling machine 23 belong to the prior art and will not be described here. For example, the upper and lower rice husker 22 are equipped with displacement sensors, which can follow and collect the linear displacement of the swing rubber roller, control the electric servo motor / stepping motor to drive the swing rubber rollers of the upper and lower rice husker forward and backward respectively, so as to adjust the gap between each pair of swing rubber rollers and the fixed rubber roller, and apply the rice husking pressure by the spring, so as to ensure the stable husking effect of the grains; and the rice milling machine 23 corresponds the whitening accuracy to the set current value of the whitening motor, and compares the actual working current of the rice milling motor with the set current value, so as to realize negative feedback control of the pneumatic pressure gate device of the rice milling machine, realize adaptive adjustment of the rice milling accuracy, and ensure the stable whitening accuracy effect.

The dust-containing airflow is sucked away by the fan 26 and discharged after dust removal by the dust filter cartridge 25, thereby realizing the recycling of by-products in the rice quality inspection process and reducing pollution to the environment. In addition, a blower 33 is installed at the bottom discharge port of the sacron 27.

[0029] Optionally, at least one of the first silo 1, the second silo 5, the third silo 8, the fourth silo 11 and the fifth silo 14 is installed with a dust removal filter cartridge 25.

When the third metering scale 12 completes the first batch of unloading, the controller controls the second valve 29 to switch to connect with the fourth conveyor 13, so that the rice discharged from the second and third times until the penultimate unloading is transported to the fifth silo 14 for subsequent detection and analysis.

In addition, the demultiplexer 15 is also connected to the third collection box 32, and the discarded samples of the demultiplexer 15 flow into the third collection box 32 for storage and are manually cleaned on time.

[0032] In addition, the intelligent rice quality detection equipment also includes a touch screen, and the controller is electrically connected to the touch screen. The touch screen serves as a human-computer interaction interface, which can control the start and stop commands of the whole machine, display the operating conditions, and display and record rice quality detection parameters.

[0033] It can be understood that in order to better illustrate the working principle of the intelligent rice quality detection device of the utility model, the rice quality detection process is first described as follows. The dry rice sample with a mass of m is sent into the first silo 1 by the sampling system, and the detection equipment is started by one key through the touch screen. The moisture meter 18, the cleaning screen 3, and the first conveyor 4 start to start. The first silo 1 is equipped with a metal magnetic separation device to remove metal impurities. About 300g of the sample enters the moisture detection silo 17 through the bypass overflow port for moisture detection. The moisture detection is carried out simultaneously with the back-road detection, which shortens the entire detection process time. Next, the pneumatic feed door of the first metering scale 2 is controlled to open, and the sample is fed into the first metering scale 2. When the mass of the material in the first metering scale 2 reaches the metering setting value m1, the pneumatic feed door of the first metering scale 2 is controlled to close and the pneumatic discharge door is controlled to open, and automatic unloading begins. The sample flows into the cleaning screen 3 through the pneumatic three-way valve to screen out impurities such as straw and small impurities. The impurities are absorbed and settled into the by-product collection box 28 through the by-product collection device, and the clean sample continuously enters the second silo 5 through the first conveyor 4. After the moisture content of the excess material in the first silo 1 is completed, it is discharged into the sample bag 21 through the other port of the pneumatic three-way valve at the same time as the material for moisture inspection. The mass of the material m-m1 retained in the sample bag 21 is not included in the calculation of the finished product yield.

[0034] Then, the target weighing value of the second metering scale 6 is set to 1kg, and the material is unloaded once it reaches 1kg. The last unloading is automatically unloaded after a delay of 10 seconds after no feeding, so as to ensure the continuous and rapid operation of the entire process. For example, the setting value of the first metering scale 2 is m1=10kg, and 0.6kg of impurities are removed. The last weighing value of the second metering scale 6 is 0.4kg, which does not reach the target value of 1kg. After the weighing value is 0.4kg, it is delayed for another 10 seconds, and the weighing value has not changed, and the last unloading is automatically completed. Among them, the total mass of materials weighed from the first to the last time by the second metering scale 6 is m2.

[0035] Next, the clean sample coming out of the cleaning screen 3 continuously enters the second silo 5 through the first conveyor 4, the pneumatic feed door of the second metering scale 6 is controlled to open, the material enters the second metering scale 6, and the material is unloaded when the target value of 1kg is reached. The second conveyor 7 is started to convey the rice into the third silo 8. After the feed sensor of the rice hulling and milling combination machine senses that there is material, the vibrating feeder, rice hulling and milling combination machine, white rice sieve 9 and third conveyor 10 of the rice hulling and milling combination machine are automatically started. The rice hulling and milling combination machine is composed of two rice hullers 22 connected in series up and down, and a rice milling machine 23, or 1 to 3 rice milling machines 23 connected in series downward. According to the displacement sensors configured on the upper and lower rice husker 22, the linear displacement of the swinging rubber rollers of the upper and lower rice husker 22 is collected, and the servo motor / stepping motor is controlled to drive the swinging rubber rollers of the upper and lower rice husker 22 to move forward and backward respectively, and the minimum gap between each pair of swinging rubber rollers and the fixed rubber rollers is adjusted, and the rice husking pressure is applied by the spring to ensure the stable husking effect of the grains; at the same time, the whitening accuracy is corresponding to the set current value of the whitening motor, and the actual working current of the rice milling motor is compared with the set current value, and the pneumatic pressure gate device of the rice milling machine is automatically adjusted by negative feedback to achieve adaptive adjustment of the rice milling accuracy and achieve stable whitening accuracy. The rice enters the rice husker and milling machine evenly and becomes rice after processing. The rice enters the white rice screen 9 continuously, and the small broken rice is screened and enters the small broken rice collection bucket 34. The screened rice is transported to the fourth silo 11 through the third conveyor 10, and the husk, bran powder and dust generated during the processing of the rice husker and milling machine are collected, transposed, absorbed and settled into the by-product collection box 28.

[0036] The third metering scale 12 is the same as the second metering scale 6, and the target metering value is 1kg. When the target value 1kg is reached, the material is discharged once. The last discharge is automatically discharged after a delay of 10 seconds after no feeding. After the rice enters the third metering scale 12, the target value 1kg is reached and the first discharge begins. The rice discharged for the first time enters the first collecting box 30 through the three-way valve bypass, and the rice discharged for the second and third times until the penultimate discharge is lifted to the fifth silo 14 through the three-way valve and the fourth conveyor 13. The rice in the fifth silo 14 enters the reduction meter 15 with an adjustable reduction ratio. The retained sample after reduction enters the rice analyzer 16 for analysis and detection. The rice analyzer 16 calculates the appearance quality data such as rice yield, broken rice rate, large broken rate, small broken rate, chalky rate, heavy chalky rate, yellow rice rate, skin retention rate, and spot rate, and then transmits them to the computer system. The retained sample after analysis flows into the second collecting box 31 and is manually cleaned on time. The discarded samples of the divider 15 flow into the third collection box 32 and are manually cleaned on time. Until the third metering scale 12 completes the last unloading, the total material mass from the first to the last weighing of the third metering scale 12 is m3.

[0037] The rice mass m1 measured by the first weighing scale 2, the total rice mass m2 measured by the second weighing scale 6, and the total rice mass m3 measured by the third weighing scale 12, then the impurity rate is: (m1-m2) / m1×100%, the rice yield rate is: m3 / m1×100%, and the finished product yield rate is: m3 / m2×100%. The moisture detection takes 2 minutes, and the entire detection process takes about 6 minutes, which greatly improves the detection efficiency and shortens the detection cycle.

[0038] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
