Description

Technical Field

[0001] This application relates to the field of millet screening technology, and in particular to a millet quality screening device. Background Technology

[0002] In current millet processing plants, screening millet of different qualities is a common process. With the increasing demand for production efficiency, the traditional manual screening method can no longer meet the needs of large-volume, high-precision screening. At present, the industry needs an automated device for screening millet of different qualities.

[0003] A related millet quality screening device includes a fixed housing, a pneumatic component, and a detection component. The fixed housing provides installation space for the pneumatic component and the detection component, and also provides a channel for the detection of millet. The detection component detects the millet passing through the fixed housing, and the pneumatic component blows away the millet that does not meet the quality standards detected by the detection component, thus completing the screening of millet of different qualities.

[0004] However, the existing millet quality screening equipment can only perform preliminary screening of millet quality through detection components, and cannot perform more refined screening of millet, thus failing to meet the needs of millet processing plants for screening millet of different qualities. Utility Model Content

[0005] In order to reduce the problem that millet quality screening equipment cannot perform fine screening of millet, this application provides a millet quality screening equipment.

[0006] This application provides a millet quality screening device, which adopts the following technical solution:

[0007] A millet quality screening device includes:

[0008] A fixed housing is fixedly installed on the ground, and a screening chamber is provided inside the fixed housing.

[0009] The feeding component is fixedly installed inside the screening chamber and conveys the millet that enters the screening chamber.

[0010] The screening component is fixedly installed inside the screening chamber and screens the millet according to its quality.

[0011] The conveying component is fixedly installed inside the screening chamber. The conveying component transfers the screened millet to the feeding component for secondary screening.

[0012] By adopting the above technical solution, the fixed shell provides installation space for the millet quality screening equipment. The feeding component can evenly spread the millet placed above the feeding component and convey it to the screening component. The screening component can classify the millet according to its size and color. The conveying component can transfer the larger millet screened out by the screening component to the feeding component for secondary screening, thereby improving the screening accuracy of the millet quality screening equipment.

[0013] Optional, the feeding components include:

[0014] The first motor is horizontally fixed on the periphery of the fixed housing, and the output end of the first motor passes through the fixed housing.

[0015] The active roller is horizontally rotatable inside the screening chamber, and one end of the active roller is fixedly connected to the output end of the first motor.

[0016] The driven roller is horizontally rotatable within the screening chamber and is arranged parallel to the driving roller.

[0017] The conveyor belt has one end wound around the drive roller and the other end wound around the driven roller. The drive roller drives the conveyor belt to rotate synchronously.

[0018] The flat plate is fixedly installed inside the screening chamber and is perpendicular to the conveyor belt.

[0019] By adopting the above technical solution, the rotation of the first motor can drive the active roller to rotate synchronously, the rotation of the active roller can drive the conveyor belt to rotate synchronously on the active roller and the driven roller, the rotation of the conveyor belt can drive the millet on the conveyor belt to be conveyed along the length of the fixed shell, and the smoothing plate can smooth the millet accumulated on the conveyor belt, so that the millet on the conveyor belt is evenly spread on the conveyor belt, reducing the accumulation of millet on the conveyor belt, thereby reducing the accumulation of millet during screening by the screening component and improving the screening efficiency of the screening component.

[0020] Optionally, a first discharge port and a second discharge port are provided on the periphery of the fixed housing, both of which are connected to the screening chamber. The screening assembly includes:

[0021] The sieve plate is fixedly installed in the screening chamber, and two sets of sieve plates are symmetrically arranged along the center line of the fixed shell length direction.

[0022] Vibrating blocks are fixedly installed on the periphery of the sieve plate, with each vibrating block corresponding to a sieve plate.

[0023] The buffer plate is fixedly connected to the sieve plate, the buffer plate is parallel to the sieve plate, and the buffer plate and the sieve plate correspond one-to-one.

[0024] The first guide plate is fixedly installed in the screening chamber. One end of the first guide plate extends out of the fixed housing through the first discharge port, and the other end of the first guide plate is correspondingly installed at the lower end of the conveying assembly.

[0025] The second guide plate is fixedly installed in the screening chamber. One end of the second guide plate extends out of the fixed housing through the first discharge port, and the other end of the second guide plate extends out of the fixed housing through the second discharge port.

[0026] A chromatograph is fixedly installed inside the sieving chamber. The chromatograph detects the color of the millet to identify particles with abnormal color.

[0027] An air pump is fixedly installed inside the screening chamber.

[0028] By adopting the above technical solution, the sieve plate can sieve the millet, allowing millet smaller than the sieve holes to pass through the sieve plate and fall onto the buffer plate, while millet larger than the sieve holes passes over the sieve plate. The vibrating block activates, causing the sieve plate to vibrate during sieving. This vibration reduces the probability of millet remaining on the sieve plate, improving sieving efficiency. When the millet falls onto the buffer plate, it is cushioned, reducing the probability of splashing within the sieving chamber. The first and second guide plates guide the millet sieved by the sieve plate. The chromatograph identifies the color of the millet passing through the first and second guide plates. The air pump blows away particles with abnormal color identified by the chromatograph from the first and second guide plates, removing impurities from the millet. Finally, the first and second guide plates transport the sieved millet out of the sieving chamber through the first and second discharge ports, respectively. Through the coordinated use of the sieve plate, chromatograph, and air pump, impurities in the millet are removed, and the millet is separated into two categories based on size.

[0029] Optionally, the delivery components include:

[0030] The collection shell is vertically fixed inside the screening chamber. The collection shell has a collection cavity inside, and an inlet and a third outlet are provided on the periphery of the collection shell. Both the inlet and the third outlet are connected to the collection cavity.

[0031] The collecting plate is fixedly installed in the screening chamber. The upper end of the collecting plate is corresponding to the lower end of the first guide plate, and the lower end of the collecting plate is corresponding to the feed inlet.

[0032] The second motor is vertically fixed at the lower end of the collection housing, and the output end of the second motor passes through the collection housing.

[0033] The screw conveyor is vertically installed in the collection chamber. The lower end of the screw conveyor is fixedly connected to the output end of the second motor, and the outer periphery of the screw conveyor is in contact with the inner wall of the collection shell.

[0034] The material collection inclined plate is fixedly installed on the outer periphery of the material collection shell. One end of the material collection inclined plate is set corresponding to the third discharge port, and the other end of the material collection inclined plate is set corresponding to the conveyor belt.

[0035] By adopting the above technical solution, the collection shell provides installation space for the conveying components. The collection plate collects millet that is larger than the screen holes and screened out by the screening components, and conveys it to the collection chamber through the feed inlet. The rotation of the second motor can drive the screw conveyor to rotate synchronously. The rotation of the screw conveyor can convey the millet in the collection chamber upward along the collection chamber. The millet reaches the upper end of the collection chamber through the conveying of the screw conveyor plate and leaves the collection chamber through the third discharge port, falling onto the collection inclined plate. The collection inclined plate conveys the millet to the conveyor belt, so that the millet is conveyed to the screening components for secondary screening.

[0036] Optionally, a feed hopper is fixedly installed on the upper end of the fixed housing, and the lower end of the feed hopper extends into the screening chamber, with the lower end of the feed hopper corresponding to the conveyor belt.

[0037] By adopting the above technical solution, workers can place the millet to be screened into the feed hopper, and the millet is then placed onto the conveyor belt, which reduces the workload of workers and improves the efficiency of millet screening.

[0038] Optionally, two sets of feeding assemblies are symmetrically arranged along the centerline of the fixed housing width direction.

[0039] By adopting the above technical solution, the two sets of feeding components are respectively set to the feed hopper and the collecting inclined plate. The feeding component set to the feed hopper can convey unscreened millet, and the feeding component set to the collecting inclined plate can convey screened millet. The two sets of feeding components ensure that the millet does not affect each other during the primary and secondary screening.

[0040] Optionally, two sets of separation tanks are provided on both the first and second guide plates, with the chromatograph and the air pump corresponding one-to-one with the separation tank.

[0041] By adopting the above technical solution, when the millet slides down through the first guide plate and the second guide plate and passes through the separation tank, the air pump starts and blows out high-speed gas, which blows the abnormal color particles identified by the chromatograph into the separation tank, thereby removing impurities from the millet.

[0042] Optionally, a buffer pad is provided on the side of the buffer plate near the sieve plate, and the buffer pad is made of food-grade silicone.

[0043] By adopting the above technical solution, the buffer pad can cushion the millet that falls onto the buffer plate, reducing the probability of millet splashing in the sieving chamber.

[0044] Optionally, a waste bin is slidably installed inside the fixed housing.

[0045] By adopting the above technical solution, the waste bin can collect the impurities blown out by the air pump through the separation tank, making it easier for staff to handle them centrally and reducing the workload of the staff.

[0046] In summary, the embodiments of the present invention provide a millet quality screening device, which includes at least one of the following beneficial technical effects:

[0047] 1. The fixed housing provides installation space for the millet quality screening equipment. The feeding component can evenly spread the millet placed above the feeding component and convey it to the screening component. The screening component can classify the millet according to its size and color. The conveying component can transfer the larger millet screened out by the screening component to the conveyor belt for secondary screening, thereby improving the screening accuracy of the millet quality screening equipment.

[0048] 2. The collection shell provides installation space for the conveying components. The collection plate collects millet larger than the screen holes that has been screened out by the screening components and conveys it to the collection chamber through the feed inlet. The rotation of the second motor can drive the screw conveyor to rotate synchronously. The rotation of the screw conveyor can convey the millet in the collection chamber upward along the collection chamber. The millet reaches the upper end of the collection chamber through the conveyor plate and leaves the collection chamber through the third discharge port, falling onto the collection inclined plate. The collection inclined plate conveys the millet to the conveyor belt, so that the millet is conveyed to the screening components for secondary screening. Attached Figure Description

[0058] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0059] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a millet quality screening device, including: a fixed housing 41, a feeding component 1, a screening component 2, and a conveying component 3. The fixed housing 41 is fixedly installed on the ground, and a screening chamber 42 is provided inside the fixed housing 41. The feeding component 1 is fixedly installed in the screening chamber 42 and conveys the millet entering the screening chamber 42. The screening component 2 is fixedly installed in the screening chamber 42 and screens the millet according to its quality. The conveying component 3 is fixedly installed in the screening chamber 42 and conveys the screened millet to the feeding component 1 for secondary screening.

[0060] In this embodiment, the fixed housing 41 is rectangular, providing installation space for the millet quality screening equipment. A feed hopper 45 is fixedly installed on the upper end of the fixed housing 41, with its lower end extending into the screening chamber 42. The lower end of the feed hopper 45 corresponds to the feeding assembly 1. Workers place the millet to be screened into the feed hopper 45, which then passes it onto the feeding assembly 1, reducing the workload of the workers. The feeding assembly 1 evenly spreads the millet and conveys it to the screening assembly 2. The screening assembly 2 first screens the millet by size and then removes impurities with abnormal color, completing the quality screening of the millet. Two sets of feeding assemblies 1 are symmetrically arranged along the center line of the fixed housing 41's width direction. The conveying assembly 3 can screen out larger-sized millet from the screening assembly 2. The millet is transferred to the feeding component 1, which is located away from the feed hopper 45. The feeding component 1 then transfers the millet back to the screening component 2 for secondary screening, improving the screening accuracy of the millet flat screening equipment. A waste bin 51 is slidably installed inside the fixed housing 41. The waste bin 51 is rectangular and can collect impurities removed from the millet by the screening component 2. When the waste bin 51 is full of impurities, the operator can operate the waste bin 51 to slide out from the fixed housing 41, making it easy for the operator to clean up the impurities and reducing the workload of the operator. The screening component 2 can screen the millet into two types according to its size and remove impurities according to its color. Through the cooperation of the conveying component 3 and the feeding component 1, the millet can be screened twice, improving the screening accuracy of the millet quality screening equipment.

[0061] In practical use, the operator places the millet to be screened into the feed hopper 45. The millet is then fed onto the feeding assembly 1, which transfers it to the screening assembly 2 for screening. The screening assembly 2 separates the millet into two categories based on its size and removes impurities. The waste bin 51 collects the removed impurities. When the waste bin 51 is full, the operator can operate it to slide out from the fixed housing 41 and remove the impurities. Larger millet pieces are transferred to another feeding assembly 1 via a transport assembly. The feeding assembly 1 then transfers the larger millet pieces back to the screening assembly 2 for secondary screening. This secondary screening improves the millet quality screening equipment's ability to finely screen millet.

[0062] Combination Figure 1 and Figure 3In one specific embodiment, the feeding assembly 1 includes: a first motor 11 horizontally fixedly disposed on the periphery of the fixed housing 41, the output end of the first motor 11 passing through the fixed housing 41; a drive roller 12 horizontally rotatably disposed in the screening chamber 42, one end of the drive roller 12 being fixedly connected to the output end of the first motor 11; a driven roller 13 horizontally rotatably disposed in the screening chamber 42, the driven roller 13 being parallel to the drive roller 12; one end of the conveyor belt 14 being wound around the drive roller 12, the other end of the conveyor belt 14 being wound around the driven roller 13; the drive roller 12 driving the conveyor belt 14 to rotate synchronously; and a flat plate 15 fixedly disposed in the screening chamber 42, the flat plate 15 being perpendicular to the conveyor belt 14.

[0063] In this embodiment, the active roller 12 and the driven roller 13 are both cylindrical. Both the active roller 12 and the driven roller 13 are parallel to one side of the fixed housing 41 in the width direction. The lengths of the active roller 12 and the driven roller 13 are the same as the width of the transmission belt. The output end of the first motor 11 passes through the fixed housing 41, and the rotation of the output end of the first motor 11 is not affected by the fixed housing 41. The rotation of the first motor 11 can drive the active roller 12 to rotate synchronously. The rotation of the active roller 12 can drive the conveyor belt 14 to move the millet along the length direction of the fixed housing 41. The millet falls onto the screening component 2 for screening under the transmission of the conveyor belt 14. The smoothing plate 15 is rectangular and has a certain gap with the conveyor belt 14. The smoothing plate 15 can smooth the millet accumulated on the conveyor belt 14, so that the millet on the conveyor belt 14 is evenly spread on the conveyor belt 14, thereby reducing the accumulation of millet during screening by the screening component 2 and improving the screening efficiency of millet.

[0064] In practical use, the staff places millet into the feed hopper 45, and the millet is placed on the conveyor belt 14 through the feed hopper 45. The first motor 11 is started, and the rotation of the first motor 11 drives the active roller 12 to rotate synchronously. The rotation of the active roller 12 drives the conveyor belt 14 to rotate synchronously on the active roller 12 and the driven roller 13. The rotation of the conveyor belt 14 drives the millet to move along the length direction of the fixed shell 41. When the millet passes through the gap between the smoothing plate 15 and the transmission belt, the smoothing plate 15 smooths the millet accumulated on the conveyor belt 14, so that the millet can be evenly spread on the conveyor belt 14. The conveyor belt 14 continues to transport the millet. When the millet reaches the end of the conveyor belt 14 near the driven roller 13, the millet falls from the conveyor belt 14 onto the screening component 2 for screening.

[0065] Combination Figure 2 , Figure 3 and Figure 4In one specific embodiment, a first discharge port 43 and a second discharge port 44 are provided around the fixed housing 41. Both the first discharge port 43 and the second discharge port 44 are connected to the screening chamber 42. The screening assembly 2 includes: a screen plate 21 fixedly disposed in the screening chamber 42, with two sets of screen plates 21 symmetrically arranged along the center line of the length direction of the fixed housing 41; vibrating blocks 22 fixedly disposed around the screen plate 21, with each vibrating block 22 corresponding to one screen plate 21; a buffer plate 23 fixedly connected to the screen plate 21, parallel to the screen plate 21, with each buffer plate 23 corresponding to one screen plate 21; and a first guide plate 24 fixedly disposed in the screening chamber. Inside the sieve chamber 42, one end of the first guide plate 24 extends out of the fixed housing 41 through the first discharge port 43, and the other end of the first guide plate 24 is correspondingly set with the lower end of the conveying assembly 3. The second guide plate 25 is fixedly set in the sieve chamber 42. One end of the second guide plate 25 extends out of the fixed housing 41 through the first discharge port 43, and the other end of the second guide plate 25 extends out of the fixed housing 41 through the second discharge port 44. The chromatograph 26 is fixedly set in the sieve chamber 42. The chromatograph 26 detects the color of the millet to identify particles with abnormal color. The air pump 27 is fixedly set in the sieve chamber 42.

[0066] In this embodiment, the sieve plate 21 is rectangular, and multiple sets of sieve holes are provided on the sieve plate 21. The diameter of the sieve holes is determined according to the size of the millet to be sieved by the millet quality sieving equipment. In this embodiment, the diameter of the sieve holes is not specifically limited. The vibrating block 22 is rectangular, and it can vibrate after being started. Vibration can reduce the probability of millet remaining on the sieve plate 21 and improve the sieving efficiency of the sieve plate 21. The vibration principle of the vibrating block 22 is prior art in this application, so the vibration principle of the vibrating block 22 is not specifically described in this embodiment. The buffer plate 23 is rectangular, and a buffer plate 23 is provided on the side near the sieve plate 21. A buffer pad 50, made of food-grade silicone, is provided to cushion millet falling onto the buffer plate 23, reducing the probability of millet splashing within the sieving chamber 42. Two sets of sieve plates 21, vibrating blocks, and buffer plates 23 are symmetrically arranged along the centerline of the fixed housing 41. The two sets of sieve plates 21 are respectively positioned corresponding to the two sets of feeding components 1, ensuring that the millet does not interfere with each other during the initial and secondary sieving processes. The first guide plate 24 and the second guide plate 25 are L-shaped, each equipped with two sets of separation tanks 46. The chromatograph 26 and the air pump 27 are each associated with one of the separation tanks 46. Correspondingly, the chromatograph 26 can identify the color of the passing millet, and the air pump 27 can emit high-speed gas to blow away the abnormally colored particles identified by the chromatograph 26 through the separation tank 46; the longer end of the first guide plate 24 extends out of the fixed housing 41 through the first discharge port 43, and the shorter end of the first guide plate 24 is correspondingly set with the conveying assembly 3. After being screened by the sieve plate 21, the smaller millet falls to the longer end of the first guide plate 24. After impurities are removed by the chromatograph 26 and the air pump 27, it leaves the fixed housing 41 through the first discharge port 43 after being conducted by the first guide plate 24. The larger millet falls out after being screened by the sieve plate 21. The millet falls to the shorter end of the first guide plate 24, where it is filtered by the chromatograph 26 and the air pump 27 to remove impurities before being transferred to the conveying assembly 3. After the millet passes through the sieve plate 21 for secondary sieving, the smaller millet falls to the end of the second guide plate 25 near the first discharge port 43, where it is filtered by the chromatograph 26 and the air pump 27 to remove impurities before leaving the fixed housing 41 through the first discharge port 43. The larger millet falls to the end of the second guide plate 25 near the second discharge port 44, where it is filtered by the chromatograph 26 and the air pump 27 to remove impurities before leaving the fixed housing 41 through the second discharge port 44. This completes the secondary sieving of the millet and improves the sieving accuracy of the millet quality sieving equipment.

[0067] In practical use, when millet falls from conveyor belt 14 onto sieve plate 21, vibrating block 22 is activated to vibrate. Sieve plate 21 vibrates and sieves the millet. Millet smaller than the sieve holes on sieve plate 21 falls onto buffer plate 23 and slides onto the end of first guide plate 24 near first discharge port 43. As the millet slides across separation tank 46 on first guide plate 24, chromatograph 26 identifies the color of the passing millet. When abnormally colored particles are detected, air pump 27 emits high-speed gas, blowing the abnormally colored particles identified by chromatograph 26 through separation tank 46 away from first guide plate 24. Impurities enter waste bin 51, and millet after impurity removal leaves through first discharge port 43. Millet larger than the sieve holes on sieve plate 21 slides onto the first discharge port 43. One guide plate 24 is located near one end of the conveying component 3. After being transported by the conveying component 3 and the gift-giving component, the millet falls onto another set of sieve plates 21. After being screened by the other set of sieve plates 21, millet smaller than the sieve holes on the sieve plate 21 slides onto the buffer plate 23 and then onto the second guide plate 25 near the first discharge port 43. After impurities are removed by the chromatograph 26 and the air pump 27, the millet leaves through the first discharge port 43. Millet larger than the sieve holes on the sieve plate 21 slides onto the second guide plate 25 near the second discharge port 44. After impurities are removed by the chromatograph 26 and the air pump 27, the millet leaves through the second discharge port 44. Through two screenings by the sieve plates 21 and the removal of impurities by the chromatograph 26 and the air pump 27, the screening accuracy of the millet quality screening equipment is improved.

[0068] Combination Figure 2 and Figure 3 In one specific embodiment, the conveying assembly 3 includes: a collection housing 31 vertically fixedly disposed within a screening chamber 42; a collection cavity 47 disposed inside the collection housing 31; an inlet 48 and a third outlet 49 disposed around the periphery of the collection housing 31, both the inlet 48 and the third outlet 49 communicating with the collection cavity 47; a collection plate 32 fixedly disposed within the screening chamber 42; the upper end of the collection plate 32 corresponding to the lower end of the first guide plate 24; and the lower end of the collection plate 32 corresponding to the inlet 48; and a second motor. The second motor 33 is vertically fixed at the lower end of the collection housing 31. The output end of the second motor 33 passes through the collection housing 31. The screw conveyor is vertically installed in the collection chamber 47. The lower end of the screw conveyor is fixedly connected to the output end of the second motor 33. The outer periphery of the screw conveyor is in contact with the inner wall of the collection housing 31. The collection inclined plate 35 is fixedly installed on the outer periphery of the collection housing 31. One end of the collection inclined plate 35 is correspondingly installed with the third discharge port 49, and the other end of the collection inclined plate 35 is correspondingly installed with the conveyor belt 14.

[0069] In this embodiment, the lower end of the collecting housing 31 is rectangular, and the upper end is cylindrical. The upper end of the second motor 33 is fixedly connected to the lower end of the collecting housing 31. The output end of the second motor 33 passes through the collecting housing 31, and its rotation is unaffected by the fixed housing 41. The rotation of the second motor 33 can drive the screw conveyor to rotate synchronously. The collecting plate 32 can collect the millet conveyed by the first guide plate 24 and transfer it to the collecting cavity 47 through the feed inlet 48. The screw conveyor rotates... The screw conveyor can drive the millet in the collection chamber 47 to move upward along the length of the collection shell 31. When the screw conveyor transports the millet to the upper end of the collection chamber 47, the millet leaves the collection chamber 47 through the third discharge port 49 and is transferred to the collection inclined plate 35. The collection inclined plate 35 is L-shaped and the inclination angle of the collection inclined plate 35 should be greater than 15 degrees to facilitate the millet sliding onto the conveyor belt 14. The millet is transported to the conveyor belt 14 above the second guide plate 25 through the collection inclined plate 35, and secondary screening is achieved through the transmission of the conveyor belt 14.

[0070] In practical use, when larger millet grains are conveyed to the collecting plate 32 via the first guide plate 24, the millet grains are collected by the collecting plate 32 and enter the collecting chamber 47 through the feed inlet 48. The second motor 33 starts and rotates, driving the screw conveyor to rotate synchronously. The rotation of the screw conveyor can drive the millet grains in the collecting chamber 47 to move upward along the length of the collecting shell 31. The millet grains fall onto the collecting inclined plate 35 through the third discharge port 49. The millet grains slide onto the conveyor belt 14 located above the second guide plate 25 through the collecting inclined plate 35. The millet grains are transported by the conveyor belt 14 to achieve secondary screening, thereby improving the screening accuracy of the millet quality screening equipment.

[0071] It should be noted that the first motor 11, the second motor 33, the vibrating block 22, the chromatograph 26, and the air pump 27 are electrically connected to an external power source. The millet quality screening equipment is equipped with a PLC control panel, which is electrically connected to the first motor 11, the second motor 33, the vibrating block 22, the chromatograph 26, and the air pump 27. The PLC control panel can control the rotation of the first motor 11 and the second motor 33, the vibration of the vibrating block 22, the color recognition of the millet by the chromatograph 26, and the high-speed gas blown out by the air pump 27.

[0072] The implementation principle of this application is as follows: Workers place the millet to be screened into the feed hopper 45. The first motor 11 rotates, driving the drive roller 12 and the conveyor belt 14 to rotate synchronously. The smoothing plate 15 smooths the millet as it passes over the conveyor belt 14, ensuring the millet is evenly spread on the conveyor belt 14. The conveyor belt 14 transports the millet to the sieve plate 21. The vibrating block 22 starts and vibrates, thereby improving the screening efficiency of the sieve plate 21. Millet smaller than the sieve holes on the sieve plate 21 falls onto the buffer plate 23 and slides onto the first guide plate 24, close to the first... At one end of the discharge port 43, as millet passes through the separation tank 46, the chromatograph 26 performs color identification on the passing millet. When abnormally colored particles are detected, the air pump 27 emits high-speed gas, blowing the abnormally colored particles identified by the chromatograph 26 through the separation tank 46 away from the first guide plate 24. The impurities enter the waste bin 51, and the millet after removing the impurities leaves through the first discharge port 43. Millet larger than the sieve holes on the sieve plate 21 is transferred to the collection plate 32 through the first guide plate 24. After being collected by the collection plate 32, the millet passes through... The feed enters the collection chamber 47 through the inlet 48. The second motor 33 rotates and drives the screw conveyor to rotate synchronously. The rotation of the screw conveyor drives the millet in the collection chamber 47 to be transported upward along the length of the collection shell 31. The millet falls onto the collection inclined plate 35 through the third outlet 49. The millet slides onto the conveyor belt 14 located above the second guide plate 25 through the collection inclined plate 35. The millet is then transported onto the screen plate 21 connected to the second guide plate 25 by the conveyor belt 14. Millet smaller than the screen holes on the screen plate 21 slides into the buffer. Millet particles larger than the sieve holes on the sieve plate 21 slide onto the second guide plate 25 near the first discharge port 43. After impurities are removed by the chromatograph 26 and the air pump 27, they leave through the first discharge port 43. Millet particles larger than the sieve holes on the sieve plate 21 slide onto the second guide plate 25 near the second discharge port 44. After impurities are removed by the chromatograph 26 and the air pump 27, they leave through the second discharge port 44. Through two sieves on the sieve plate 21 and the removal of impurities by the chromatograph 26 and the air pump 27, the sieve accuracy of the millet quality sieve equipment is improved.
