Description

Technical Field

[0001] This invention relates to the field of millet processing technology, and in particular to a screening device and screening method for processing organic millet. Background Technology

[0002] Millet is an important food crop. During processing, it is necessary to remove large impurities such as withered grass and stalks to ensure reliable product quality. Current technologies often use screening devices equipped with inclined filters to screen millet.

[0003] For example, Chinese Patent Publication No. CN221063460U discloses a millet screening device, which includes a vibrating platform. A screening box is fixedly connected to the upper surface of the vibrating platform, and an inclined plate is fixedly connected to the inner wall of the screening box. The upper surface of the inclined plate has a through hole, and the inner wall of the through hole is arc-shaped. Two fixing strips are fixedly connected to the lower surface of the inclined plate. The vibrating platform drives the screening box to vibrate, and the inclined plate vibrates. Millet falls onto the inclined plate, and the two half-screening holes merge to screen the material. Impurities are screened out through the inclined plate, and millet and smaller impurities fall onto the lower inclined plate through the half-screening holes. The lower inclined plate then vibrates, and the millet is moved out of the screening box and collected through the inclined plate. When the half-screening holes are blocked by material, the clamping bolts can be loosened, and the rotating disk drives the rotating rod to rotate. Under the limit of the rod, the two moving strips separate, thereby allowing the blocked material to fall off for easy cleaning.

[0004] This application uses two inclined plates arranged vertically to screen millet. The raw material moves freely from the high side to the low side of the inclined plates to complete the screening. During this process, the millet may be located on top of large impurities and discharged synchronously with the large impurities, thus failing to achieve effective screening of millet based on large impurities, which has certain limitations in use.

[0005] Therefore, it is necessary to provide a screening device and screening method for processing organic millet to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a screening device and screening method for processing organic millet, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, a screening device and screening method for organic millet processing are designed, which can effectively screen large impurities in millet and allow large impurities to be discharged in a timely manner.

[0008] Based on the above ideas, the present invention provides the following technical solution: a screening device for processing organic millet, comprising a housing and a combing plate, wherein a screening component for screening millet and movably fitting with the combing plate is disposed inside the housing, and a base is slidably mounted on the top of the housing, wherein a control mechanism for driving the combing plate to move is disposed inside the base; the control mechanism can be activated by the base to drive the combing plate to move along the circumferential direction of the screening component, and can also drive the combing plate to reciprocate along the surface of the screening component.

[0009] As a further embodiment of the present invention: the screening component includes a filter ring fixedly installed in the housing, the filter ring is tapered and a filter cylinder is provided at the center of the ring, and filter holes are provided through the filter ring and the filter cylinder.

[0010] As a further embodiment of the present invention: the control mechanism includes a motor fixedly installed in the base and a support frame that moves synchronously with the carding plate. The output shaft of the motor is fixedly mounted with a support rod. A rotating unit is provided between the support rod and the housing, and a translation unit is provided between the support rod and the support frame.

[0011] As a further embodiment of the present invention: the rotating unit includes a gear ring fixedly mounted on the outer surface of the housing and a first gear fixedly mounted on the outer surface of the support rod, the first gear being connected to the gear ring in a transmission manner.

[0012] As a further embodiment of the present invention: the translation unit includes a first bevel gear fixedly installed on the outer surface of the support rod and a crossbar rotatably installed in the base. A second bevel gear that is connected to the first bevel gear is fixedly installed at the end of the crossbar. The support frame is threadedly sleeved on the outside of the crossbar and slides with the base.

[0013] As a further embodiment of the present invention: the translation unit includes a cam fixedly installed on the outer surface of the support rod and a push rod that slides with the base. The push rod is movably fitted with the cam and fixedly connected to the support frame. A spring is fixedly installed between the push rod and the base.

[0014] As a further embodiment of the present invention: a card holder that slides and engages with the surface of the housing is fixedly installed on the base, the card holder having an inverted U-shaped design and being snapped onto the housing.

[0015] As a further aspect of the present invention: the translation unit drives the combing plate to move along the surface of the filter ring through the support frame, and the combing plate can also be moved above the filter cylinder.

[0016] As a further embodiment of the present invention: the support frame is a vertically arranged telescopic rod, the fixed end of which moves synchronously with the translation unit, and the movable end of which is fixedly connected to the combing plate.

[0017] The present invention also provides the following technical solution: a screening method for processing organic millet, wherein the raw material is fed onto the screening component and close to the combing plate, and the control mechanism is activated to drive the combing plate to move along the circumferential direction of the screening component on the one hand, and to drive the combing plate to reciprocate along the surface of the screening component on the other hand; during the circumferential movement and reciprocating movement, the screening component can make the millet flow down and filter out large impurities, and can also discharge large impurities during the reciprocating movement.

[0018] Compared with the prior art, the beneficial effects of the present invention are: through the cooperation between the screening component, the base, the combing plate and the control mechanism, the combing plate can be driven to move along the circumferential direction of the screening component, and the combing plate can also be driven to move back and forth along the surface of the screening component. During this process, the combing plate can drive the raw material to move continuously, so that millet can be quickly screened out by the screening component, which can effectively improve the screening speed and screening effect of millet.

[0019] When the combing plate moves along the surface of the screening component, it can push out large impurities, thereby enabling the screening and collection of large impurities, facilitating subsequent centralized processing, reducing the overall operational burden and ensuring the long-term stable performance of the screening component.

[0020] By using the combing plate to move the raw materials, the raw materials are evenly distributed on the screening components, improving the screening effect of millet. On the other hand, there are no restrictions on the way the raw materials are fed to the screening components, as long as they are close to the combing plate. Furthermore, it allows all areas of the screening components to come into contact with the raw materials, thereby increasing the overall utilization rate of the screening components and ensuring the effectiveness and lifespan of the screening components.

[0021] At the same time, the movement of the combing plate along the surface of the screening component also has the effect of cleaning the surface of the screening component, preventing raw materials from accumulating on the screening component and preventing raw materials from clogging the screening component, which can further ensure the use effect and service life of the screening component, making it more practical overall.

[0024] Please see Figures 1 to 6 This invention provides a screening device for processing organic millet, mainly used to improve the screening speed and effect of millet, and to promptly remove large impurities such as withered grass and stalks. The device includes a housing 1, which is a cylindrical design with an open top. Inside the housing 1 are a screening component 2 for screening millet and a combing plate 4 that is movably fitted with the screening component 2. Both the screening component 2 and the combing plate 4 allow millet to pass through while blocking large impurities. The combing plate 4 has a brush-like structure, which is a mature existing technology and will not be described in detail here. After flowing down through the screening component 2, the millet falls to the bottom of the inner part of the housing 1. An opening can be made on the outer surface of the housing 1 for the millet to be removed.

[0025] Furthermore, such as Figure 1 As shown, a base 3 is slidably mounted on the top of the housing 1. The base 3 is equipped with a control mechanism 5 for driving the carding plate 4 to move. When the control mechanism 5 is activated, it can drive the base 3 to move along the circumferential direction of the housing 1. At this time, the carding plate 4 can move along the circumferential direction of the screening component 2. At the same time, the control mechanism 5 can also drive the carding plate 4 to move back and forth along the surface of the screening component 2.

[0026] Among them, such as Figure 1As shown, when the raw material is fed into the screening component 2, the combing plate 4 moves along the circumferential direction of the screening component 2, which can push the raw material along the screening component 2, so that the millet can be quickly screened through the screening component 2 and the entire area of ​​the screening component 2 can be effectively utilized. By the combing plate 4 moving back and forth along the surface of the screening component 2, the screening speed and screening effect of the millet can be further improved, and large impurities can be sent out, thereby ensuring the long-term stable use effect of the screening component 2.

[0027] Reference Figure 2 and Figure 5 In this embodiment, preferably, the screening component 2 includes a filter ring 201 fixedly installed in the housing 1. The filter ring 201 is tapered and a filter cylinder 202 is placed at the center of the ring. The staff can manually pick up and put down the filter cylinder 202. The bottom of both the filter ring 201 and the filter cylinder 202 are provided with filter holes 203. Through the filter holes 203, millet can flow down and large impurities are blocked.

[0028] In the above structure, such as Figure 2 As shown, the filter ring 201 is used to receive the raw material, while the filter cylinder 202 is used to collect large impurities. When the raw material moves along the surface of the filter ring 201, the millet can flow down completely through the filter ring 201. Even if some millet falls into the filter cylinder 202 with the large impurities, it can still flow down through the filter holes 203 at the bottom of the filter cylinder 202. To improve the millet discharge effect of the filter cylinder 202, filter holes 203 can also be provided through the outer surface of the filter cylinder 202.

[0029] Furthermore, such as Figure 5 As shown, the top of the filter cartridge 202 may have a concave edge 204 to facilitate the guidance of large impurities to fall into the filter cartridge 202.

[0030] Reference Figures 2 to 4 In this embodiment, preferably, the control mechanism 5 includes a motor 501 fixedly installed in the base 3 and a support frame 503 that moves synchronously with the carding plate 4. The motor 501 is a servo motor 501 capable of forward and reverse rotation, and its output shaft is fixedly mounted with a support rod 502. A rotating unit 504 is provided between the support rod 502 and the housing 1. When the motor 501 starts and drives the support rod 502 to rotate, the rotating unit 504 can drive the base 3 and the motor 501 to move along the circumferential direction of the housing 1. A translation unit 505 is provided between the support rod 502 and the support frame 503. When the motor 501 starts and drives the support rod 502 to rotate, the translation unit 505 can drive the carding plate 4 to reciprocate along the surface of the filter ring 201.

[0031] To improve the sliding effect of the base 3 along the housing 1, such as Figure 4 As shown, a card holder 506 that slides and engages with the surface of the housing 1 can be fixedly installed on the base 3. The card holder 506 has an inverted U-shaped design.

[0032] Among them, such as Figure 4 As shown, the rotating unit 504 includes a gear ring 5042 fixedly installed on the outer surface of the housing 1 and a first gear 5041 fixedly installed on the outer surface of the support rod 502. The first gear 5041 is connected to the gear ring 5042 in a transmission manner. When the motor 501 starts and drives the first gear 5041 to rotate through the support rod 502, the first gear 5041 can move along the gear ring 5042, thereby driving the base 3 to move synchronously.

[0033] Furthermore, such as Figure 4 As shown, the translation unit 505 includes a first bevel gear 5051 fixedly installed on the outer surface of the support rod 502 and a crossbar 5052 rotatably installed in the base 3. A second bevel gear 5053, which is connected to the first bevel gear 5051, is fixedly installed at the end of the crossbar 5052. The support frame 503 is threaded onto the crossbar 5052 and slides with the base 3. Through the above design, the rotation of the support rod 502 can be transmitted to the crossbar 5052, causing the support frame 503 to translate along the crossbar 5052. This, in turn, drives the combing plate 4 to move horizontally back and forth along the surface of the filter ring 201. When the combing plate 4 moves, there is an overlapping area between it and the filter cartridge 202, thereby pushing large impurities into the filter cartridge 202.

[0034] It should be noted that when the crossbar 5052 drives the carding plate 4 to complete one unidirectional movement through the support frame 503, the first gear 5041 drives the base 3 to move more than one revolution along the circumferential direction of the housing 1 through the gear ring 5042. That is, when the carding plate 4 completes one unidirectional movement along the filter ring 201, the carding plate 4 has rotated at least one revolution along the filter ring 201. This ensures that when the carding plate 4 moves back and forth along the surface of the filter ring 201, the carding plate 4 can drive the raw material to contact the entire area of ​​the filter ring 201, which can achieve the effect of uniformly distributing the raw material based on the filter ring 201.

[0035] It should also be noted that, in order to ensure that the carding plate 4 can drive the raw material to move when it moves along the circumferential direction of the filter ring 201, the width dimension of the side of the carding plate 4 closer to the motor 501 is greater than the width dimension of the side away from the motor 501, so that the front and rear sides of the carding plate 4 form a similar bevel design, which can drive the raw material to move stably.

[0036] Furthermore, such as Figure 6As shown, this is a different design of the translation unit 505. In this case, the translation unit 505 may include a cam 5054 fixedly installed on the outer surface of the support rod 502 and a push rod 5055 slidably engaged with the base 3. The push rod 5055 is in contact with the outer surface of the cam 5054, and a spring 5056 is fixedly installed between the push rod 5055 and the base 3. The spring 5056 causes the push rod 5055 to tend to move towards the cam 5054, so that the cam 5054 can always drive the push rod 5055 to move horizontally when rotating. In this case, the support frame 503 can be fixedly connected to the push rod 5055.

[0037] With the above design, when the motor 501 starts and drives the carding plate 4 to move along the circumferential direction of the filter ring 201, the carding plate 4 can move horizontally back and forth multiple times along the surface of the filter ring 201. The number of back and forth movements is more than the other design of the translation unit 505. Therefore, it has a better effect on the uniform distribution of raw materials based on the filter ring 201, and it has a better effect on pushing large impurities. At the same time, it eliminates the need for a corresponding design of the number of rotations of the carding plate 4 and the movement stroke of the carding plate 4.

[0038] In the above structure, such as Figure 3 As shown, the support frame 503 can be a vertically arranged telescopic rod, with its fixed end threaded onto the outer surface of the crossbar 5052 and its movable end fixedly connected to the carding plate 4. When the carding plate 4 moves along the surface of the filter ring 201, the telescopic rod switches back and forth between the contracted and extended states.

[0039] In use, the raw material is placed on the filter ring 201 and brought close to the carding plate 4. When the motor 501 is started and the support rod 502 is rotated, the support rod 502 moves the base 3, translation unit 505, and telescopic rod along the circumferential direction of the housing 1 through the rotation unit 504. At this time, the carding plate 4 can move along the circumferential direction of the filter ring 201, and the carding plate 4 can move the raw material along the surface of the filter ring 201 in the circumferential direction. On the other hand, the support rod 502 moves the telescopic rod through the translation unit 505, and the carding plate 4 can move along the surface of the filter ring 201, thus allowing the carding plate 4 to also move the raw material along the surface of the filter ring 201. During the movement of the raw material along the filter ring 201, millet can flow down through the filter holes 203, while large impurities continue to move with the carding plate 4. Finally, when the carding plate 4 moves above the filter cylinder 202, the large impurities can fall into the filter cylinder 202.

[0040] In summary, through the cooperation of the filter ring 201, the rotating unit 504, the translation unit 505, and the telescopic rod, the combing plate 4 can be moved both circumferentially along the filter ring 201 and reciprocated along the surface of the filter ring 201. During this process, the combing plate 4 can continuously move the raw material, thereby allowing millet to be quickly screened out by the conical filter ring 201. By moving the raw material through the combing plate 4, the screening speed and screening effect of millet can be improved.

[0041] When the combing plate 4 moves along the surface of the filter ring 201 to the filter cylinder 202, it can push large impurities into the filter cylinder 202, thereby enabling the screening and collection of large impurities, facilitating subsequent centralized processing, reducing the overall operational burden and ensuring the long-term stable performance of the filter ring 201.

[0042] The movement of raw materials driven by the combing plate 4 achieves uniform distribution of raw materials based on the filter ring 201, improving the screening effect of millet. On the other hand, there are no restrictions on the feeding method of raw materials to the filter ring 201, as long as they are close to the combing plate 4. Furthermore, it allows all areas of the filter ring 201 to come into contact with the raw materials, thereby increasing the overall utilization rate of the filter ring 201 and ensuring the effectiveness and service life of the filter ring 201.

[0043] At the same time, the movement of the combing plate 4 along the surface of the filter ring 201 also has the effect of cleaning the surface of the filter ring 201, preventing raw materials from accumulating on the filter ring 201 and preventing raw materials from clogging the filter ring 201, which can further ensure the use effect and service life of the filter ring 201, and the overall practicality is higher. Example 2:

[0044] Please see Figures 1 to 10 Based on Embodiment 1, in order to improve the discharge effect of large impurities, the support frame 503 is improved: the support frame 503 now includes a cover 5031 driven by the translation unit 505. The top and bottom of the cover 5031 are respectively slidably mounted with a vertical rod 5032 and a diagonal rod 5033. A connecting rod 5034 is provided inside the cover 5031. The two ends of the connecting rod 5034 are rotatably connected to the vertical rod 5032 and the diagonal rod 5033 through universal joints. At this time, the vertical rod 5032, the connecting rod 5034 and the diagonal rod 5033 can rotate synchronously. The bottom of the diagonal rod 5033 is fixedly connected to the carding plate 4, so that when the diagonal rod 5033 rotates, it can drive the carding plate 4 to rotate synchronously based on the filter ring 201.

[0045] In the above structure, such as Figure 9 As shown, the diagonal rod 5033 is inclined and slides on the bottom of the cover 5031, and the vertical rod 5032 is slidably mounted on the top of the cover 5031. When the translation unit 505 moves the cover 5031 horizontally, the cover 5031 can move the surface of the combing plate 4 through the diagonal rod 5033. At this time, the combing plate 4 can move the diagonal rod 5033 inward into the cover 5031, while the vertical rod 5032, the connecting rod 5034 and the diagonal rod 5033 can still rotate synchronously through the universal joint.

[0046] Furthermore, a second gear 5035 is fixedly installed on the top of the vertical rod 5032, and a rack 6 that is connected to the second gear 5035 is fixedly installed inside the base 3. The thickness of the rack 6 in the vertical direction is greater than the thickness of the second gear 5035 in the vertical direction, so that when the inclined rod 5033 retracts into the cover 5031, even if the connecting rod 5034 drives the vertical rod 5032 and the second gear 5035 to move up and down, the second gear 5035 can still mesh with the rack 6 for transmission.

[0047] Furthermore, such as Figure 10 As shown, the combing plate 4 includes an inclined plate 401 fixedly connected to the inclined rod 5033. The inclined plate 401 and the surface of the filter ring 201 are designed to be parallel to each other. The top of the inclined rod 5033 and the inclined plate 401 are designed to be perpendicular to each other, so that when the inclined rod 5033 drives the inclined plate 401 to rotate, the distance between the inclined plate 401 and the surface of the filter ring 201 is equal. Several guide posts 402 are slidably installed at the bottom of the inclined plate 401. Due to gravity, the guide posts 402 can be in a downward state based on the inclined plate 401, and thus move and fit against the surface of the filter ring 201. Subsequently, when the inclined rod 5033 drives the inclined plate 401 to rotate, due to the sliding design of the guide posts 402 based on the inclined plate 401, the guide posts 402 can adaptively rise and fall relative to the bottom of the inclined plate 401 while maintaining contact with the surface of the filter ring 201.

[0048] In use, the filter ring 201, the rotating unit 504, the translation unit 505 and other structures can drive the carding plate 4 to move along the circumferential direction of the filter ring 201, and can also drive the carding plate 4 to move back and forth along the surface of the filter ring 201. The working process and effect of this part are the same as in Embodiment 1, and will not be repeated here. The difference lies in the following: When the support rod 502 drives the base 3, translation unit 505, and cover 5031 to move along the circumferential direction of the housing 1 via the rotation unit 504, the inclined plate 401 can still drive the guide column 402 to move along the circumferential direction of the filter ring 201 and drive the raw material to move; when the support rod 502 drives the cover 5031 to translate via the translation unit 505, the inclined plate 401 can still drive the guide column 402 to translate along the surface of the filter ring 201. At this time, the inclined plate 401 can drive the inclined rod 5033 to retract into the cover 5031; during this process, the vertical rod 5032, connecting rod 5034, and inclined rod 5033 can maintain synchronous rotation through the universal joint, while the vertical rod 5032 can rotate continuously through the second gear 5035 and rack 6, thereby enabling the inclined plate 401 to drive several guide columns 402 to continue to rotate along the surface of the filter ring 201.

[0049] Compared to Embodiment 1, through the cooperation of structures such as filter ring 201, cover 5031, inclined rod 5033 and guide column 402, on the basis of the inclined plate 401 moving along the circumferential direction of filter ring 201 and the surface of filter ring 201 translating, the inclined plate 401 can also continuously rotate along the surface of filter ring 201 and drive several guide columns 402 to move synchronously. In this process, the inclined plate 401 and the guide column 402 have a better effect on the uniform distribution of raw materials based on filter ring 201, and the millet is screened out faster through filter ring 201, which can further improve the screening speed of millet. Moreover, the continuous self-rotation has a better effect on the conveying of large impurities to filter cartridge 202, which can further ensure the discharge of large impurities to filter cartridge 202.

[0050] Meanwhile, the continuous self-rotation of the inclined plate 401 can prevent raw materials and large impurities from accumulating at the junction of the filter ring 201 and the shell 1 (i.e., the outer edge of the filter ring 201), which can further improve the discharge effect of large impurities; at the same time, the continuous self-rotation of the inclined plate 401 based on the filter ring 201 is also conducive to the removal of millet from large impurities, which can further ensure the screening effect of millet, and the overall functionality is stronger. Example 3:

[0051] Please see Figures 1 to 10 This invention provides a screening method for processing organic millet. The screening device used in this embodiment is either one of the screening devices in Embodiment 1 or 2, and therefore also has corresponding beneficial effects.

[0052] Specifically, the raw material is first fed onto the screening component 2 and placed close to the combing plate 4. Then, the control mechanism 5 is activated, which on the one hand drives the combing plate 4 to move along the circumferential direction of the screening component 2, and on the other hand drives the combing plate 4 to move back and forth along the surface of the screening component 2. During the circumferential movement and the back and forth movement, the screening component 2 can make the millet flow down and filter out large impurities. In addition, during the back and forth movement, large impurities can also be discharged.
