Description

Technical Field

[0001] The invention relates to the technical field of lotus seed color sorting, and in particular to a lotus seed color sorting machine. Background Art

[0002] The quality of lotus seeds after picking varies. Not only are they divided into multiple grades such as old and tender in terms of maturity, but some lotus seeds will even turn brown. The difference is mainly reflected in the color difference of lotus seeds with skin. Therefore, the quality of lotus seeds can be judged by the difference in skin color. At present, the screening of lotus seed quality is mainly through manual judgment, which is not only time-consuming and labor-intensive, but also inefficient, and has subjective errors to a certain extent.

[0003] Existing color sorters mostly use vibration to evenly feed agricultural products such as rice, cereals, and beans, which then enter the color sorting box through a slide. These agricultural products do not need to have their angles adjusted during color sorting and identification. When color sorting lotus seeds, in order to obtain accurate color sorting effects, it is usually necessary to conduct targeted screening based on the color difference at both ends of the lotus seeds.

[0004] In the prior art, for example, a patent document with announcement number CN211463969U discloses a feeding mechanism of a fresh lotus seed color sorter with skin, which includes a storage bin and a feeding hopper. The feeding hopper corresponds to a groove provided on a belt in a conveying mechanism. After the lotus seeds in the groove are transported to the edge of the conveying mechanism, they fall into the color sorting box due to gravity. After the color sorting process is completed in the color sorting box, qualified lotus seeds fall into the good product bin in the material collection box, and unqualified lotus seeds fall into the defective product bin in the material collection box, thereby achieving separation of qualified lotus seeds from unqualified lotus seeds.

[0005] It can be seen that although the prior art can also realize the conveying and color sorting of lotus seeds, similarly, when the lotus seeds fall from the feeding funnel into the groove, the conveying angle of the lotus seeds cannot be adjusted, and thus the falling trajectory of the lotus seeds cannot be adjusted. Therefore, during the color sorting process of the lotus seeds, the two ends of the lotus seeds cannot be directly facing the camera lens. At the same time, there are usually many impurity particles in the lotus seeds. If color sorting is performed directly, the impurity particles will not only affect the normal conveying of the lotus seeds, but also affect the shooting effect of the camera lens during the falling process of the lotus seeds. Summary of the invention

[0029] Beneficial effects of the present invention:

[0030] (1) After being discharged from the feed funnel, the lotus seeds of the present invention first fall into the filtering module, and the impurity particles contained in the lotus seeds are screened and filtered by the filtering module. The filtered lotus seeds can then be discharged into the vibrating material sorting tray for vibrating conveying, thereby preventing the impurity particles from affecting the normal conveying of the roller conveying module, and also preventing the impurity particles from falling together with the lotus seeds and affecting the color sorting accuracy;

[0031] (2) The present invention drives the feed funnel to rotate by rotating the module, and the feed funnel drives the filter plate to rotate synchronously, so that the lotus seeds falling on the filter plate are subjected to centrifugal motion. When the lotus seeds fall from the filter plate, they can directly fall into the vibrating material sorting plate. Correspondingly, when the impurity particles in the lotus seeds also fall onto the filter plate, based on the setting of the filter holes, the impurity particles can roll into the storage barrel. At the same time, due to a certain gap between the filter plate and the discharge end, the lotus seeds can vibrate when they fall, and some impurities attached to the surface of the lotus seeds can be shaken off.

[0032] (3) When the discharge end is driven to rotate, each ball rolls on the support ring to synchronously drive the feed funnel to vibrate up and down, which can improve the feeding efficiency of the feed funnel on the one hand, and quickly shake off the impurity particles attached to the surface of the lotus seeds on the other hand, and at the same time, prevent the impurity particles from clogging the filter holes;

[0033] (4) In the initial state of the present invention, each guide wheel abuts against the inclined guide surface at a position close to the upper side. At this time, the sealing plate and the material discharge channel are in a misaligned state. As more and more impurity particles fall into the storage barrel, the mass of the storage barrel increases accordingly. The storage barrel pulls the support rod downward under the action of gravity. The support rod synchronously drives the guide wheel to move through the drive frame. The guide wheel abuts against the inclined guide surface and pushes the wedge frame to move away from the support rod. The wedge frame synchronously drives the sealing plate to move toward the material discharge channel, so that the bottom opening area of ​​the material discharge channel gradually decreases until the lotus seeds cannot be discharged, so as to avoid the phenomenon that the lotus seeds still fall when the impurity particles in the storage barrel are cleaned later.

[0050] See also Figure 2-Figure 3 , a feeding box 2 is provided on the conveying box 3, a feeding funnel 4 is rotatably arranged on the feeding box 2, a vibrating material sorting tray 201 is provided in the feeding box 2, the vibrating material sorting tray 201 is arranged below the feeding funnel 4, and a conveying track 202 is also arranged in the feeding box 2, one end of the conveying track 202 is connected to the discharge port of the vibrating material sorting tray 201, and the other end is connected to the roller conveying module 301; specifically, in this embodiment, when a large number of lotus seeds are color sorted, the lotus seeds are first placed in the feeding funnel 4, and the lotus seeds fall into the vibrating material sorting tray 201 under the action of gravity for vibration conveying, and are discharged to the conveying track 202 through the discharge port of the vibrating material sorting tray 201, and finally slide to the roller conveying module 301 for horizontal conveying;

[0051] It also includes a filtering module arranged at the bottom of the feed funnel 4, and the filtering module is used to filter the impurity particles in the lotus seeds; it can be explained that after the lotus seeds are discharged through the feed funnel 4, they first fall to the filtering module, and the impurity particles contained in the lotus seeds are screened and filtered by the filtering module. The filtered lotus seeds can be discharged into the vibrating material sorting tray 201 for vibration transportation, thereby preventing the impurity particles from affecting the normal transportation of the roller conveying module 301, and also preventing the impurity particles from falling together with the lotus seeds and affecting the color sorting accuracy.

[0052] In addition, it should be noted that the vibrating material sorting tray 201 in this embodiment is a prior art and will not be described in detail in this embodiment.

[0053] Example 2

[0054] Based on Example 1, please refer to Figure 3-Figure 4 as well as Figure 8 and Fig.10 A discharge terminal 401 is provided at the bottom of the feed funnel 4, and a plurality of groups of discharge channels 603 with both ends connected are arranged in a circumferential array on the discharge terminal 401; specifically, four groups of discharge channels 603 are arranged in this embodiment, and the specific number of the discharge channels 603 is not limited in this embodiment, so as to meet the discharge demand of the feed funnel 4, and the lotus seeds can fall through each discharge channel 603 and be discharged onto the filter module.

[0055] In this embodiment, the filter module includes a filter disc 6 arranged at the bottom of the discharge end 401, and a plurality of groups of filter holes 601 are evenly arranged on the filter disc 6. A storage barrel 602 is arranged at the bottom of the filter disc 6, wherein a rotating module is also provided in the feed box 2, and the rotating module is used to drive the feed funnel 4 to rotate; it can be explained that the lotus seeds fall from the discharge channel 603 and fall onto the filter disc 6. In this embodiment, the feed funnel 4 is driven to rotate by the rotating module, and the feed funnel 4 synchronously drives the filter disc 6 to rotate, so that the lotus seeds falling on the filter disc 6 are subjected to centrifugal motion. When the lotus seeds fall from the filter disc 6, they can directly fall into the vibrating material processing disc 201. Correspondingly, when the impurity particles in the lotus seeds also fall onto the filter disc 6, based on the setting of the filter holes 601, the impurity particles can roll into the storage barrel 602. At the same time, due to the presence of a certain gap between the filter disc 6 and the discharge end 401, the lotus seeds can have a vibration effect when they fall, and some impurities attached to the surface of the lotus seeds can be shaken off.

[0056] In addition, the filter disc 6 is connected to the storage barrel 602 by a spiral method to facilitate disassembly and assembly. Figure 1 A box door 203 is provided on the side wall of the feed box body 2. When the impurity particles stored in the storage barrel 602 reach a predetermined amount, the box door 203 is opened to clean the impurity particles in the storage barrel 602.

[0057] See also Figure 4-Figure 5 as well as Figure 8 The rotating module includes a gear ring 406 fixedly arranged on the outside of the discharge end 401, a driving motor 404 is fixedly arranged in the feed box 2, and a gear 405 meshing with the gear ring 406 is fixedly arranged at the output end of the driving motor 404; it can be explained that when the driving motor 404 is started to drive the gear 405 to rotate, the gear 405 drives the discharge end 401 and the feed funnel 4 to rotate synchronously by meshing with the gear ring 406.

[0058] See also Figure 5 as well as Figure 10-11 , a support rod 607 is fixedly arranged on the filter disc 6, a circular groove 604 is provided at one end of the discharge end 401 facing the filter disc 6, a sleeve 605 is fixedly arranged in the circular groove 604, the other end of the support rod 607 is slidably plugged with the sleeve 605, a first spring 606 is fixedly arranged in the sleeve 605, and the other end of the first spring 606 is fixed to the support rod 607, wherein a plurality of groups of slide grooves 608 are provided on the inner wall of the sleeve 605 in a circumferential array, and a plurality of groups of holders 609 correspondingly and slidably engaged with the slide grooves 608 are correspondingly fixedly arranged on the support rod 607; specifically, three groups of slide grooves 608 are provided in this embodiment, and it can be explained that when the discharge end 401 is driven to rotate, the discharge end 401 synchronously drives the sleeve 605 to rotate, and the sleeve 605 drives the support rod 607 to rotate through the engagement of the slide groove 608 with the holder 609, and the support rod 607 can synchronously drive the filter disc 6 to rotate synchronously and stably.

[0059] As a further solution of this embodiment, please refer to Figure 4-Figure 5 as well as Fig. 9 In order to improve the discharge efficiency of the feed funnel 4, a support ring 403 is sleeved on the outer side of the discharge end 401, and the support ring 403 is fixed to the feed box 2 through a mounting frame 407. A plurality of groups of arc grooves 402 are arranged in a circumferential array on the support ring 403, wherein a plurality of groups of balls 408 corresponding to the arc grooves 402 are arranged at the bottom of the gear ring 406; specifically, when the discharge end 401 is driven to rotate, each ball 408 rolls on the support ring 403 to synchronously drive the feed funnel 4 to vibrate up and down, which can improve the feeding efficiency of the feed funnel 4 on the one hand, and quickly shake off the impurity particles attached to the surface of the lotus seeds on the other hand, and at the same time, prevent the impurity particles from clogging the filter hole 601.

[0060] In addition, in this embodiment, the thickness of the gear ring 406 is greater than the thickness of the gear 405, so that when the discharge end 401 vibrates, the gear ring 406 is prevented from losing engagement with the gear 405.

[0061] See also Figure 5 , Figure 8 as well as Fig.10 When the impurity particles stored in the storage barrel 602 reach a predetermined amount, in order to limit the lotus seeds from continuing to be discharged onto the filter plate 6, in this embodiment, a plurality of groups of sealing plates 7 for closing the material discharge channel 603 are slidably arranged at the bottom of the discharge end 401, wherein the sealing plates 7 are connected to a driving unit that drives them to move away from or close to the material discharge channel 603; it can be explained that as the impurity particles stored in the storage barrel 602 reach a predetermined amount, in this embodiment, the driving unit drives each group of sealing plates 7 to slide and interfere with the material discharge channel 603, so that the lotus seeds cannot fall;

[0062] In addition, in this embodiment, a monitoring mechanism can be provided on the feed box 2. When it is detected that no lotus seeds fall onto the filter plate 6, it means that the foreign particles stored in the storage barrel 602 have reached a predetermined amount and need to be cleaned.

[0063] In this embodiment, the driving part includes a T-slot 702 opened on each group of sealing plates 7, a T-slot seat 701 slidably connected to the T-slot 702 is fixedly arranged at the bottom of the unloading channel 603, a second spring 703 is arranged in the T-slot 702, one end of the second spring 703 is fixed to the groove wall of the T-slot 702, and the other end is fixed to the T-slot seat 701, a wedge frame 705 is fixedly arranged at the bottom of each group of sealing plates 7, and an inclined guide surface 706 is arranged on the end of the wedge frame 705 close to the support rod 607, wherein a plurality of groups of driving frames 704 are correspondingly fixedly arranged on the support rod 607, and a guide wheel 707 rollingly abutting against the inclined guide surface 706 is rotatably arranged at the bottom of the driving frame 704; specifically, in the initial state, Each guide wheel 707 abuts against the inclined guide surface 706 at a position facing upward. At this time, the sealing plate 7 and the feeding channel 603 are in a misaligned state. As more and more impurity particles fall into the storage barrel 602, the mass of the storage barrel 602 increases accordingly. The storage barrel 602 pulls the support rod 607 downward under the action of gravity, and the support rod 607 synchronously drives the guide wheel 707 to move through the driving frame 704. The guide wheel 707 pushes the wedge frame 705 to move away from the support rod 607 by abutting against the inclined guide surface 706. The wedge frame 705 synchronously drives the sealing plate 7 to move toward the feeding channel 603, so that the bottom opening area of ​​the feeding channel 603 is gradually reduced until the lotus seeds cannot be discharged.

[0064] It should also be noted that in order to prevent the sealing plates 7 from automatically resetting when cleaning the impurities in the storage barrel 602, the present embodiment requires manual application of force to the filter disc 6 to prevent the filter disc 6 from moving upward. After cleaning, the filter disc 6 can be released.

[0065] See also Figure 1-Figure 2 as well as Figure 6-Figure 7The color sorting box 1 is provided with a through slot 101 connected to the conveying box 3, and a roller conveying module 301 is arranged in the through slot 101. The roller conveying module 301 includes two groups of chains 304 arranged in parallel, and a plurality of groups of closely arranged roller bodies 302 are rotatably arranged between the two groups of chains 304. The diameter of the roller body 302 gradually increases from the center end along the axial direction to both sides. The design of this structure can be adapted to the structure of lotus seeds. The roller conveying module 301 also includes two groups of symmetrically arranged sprocket wheels 306, and a plurality of groups of arc grooves 305 for sliding engagement with the ends of the roller bodies 302 are evenly provided on the sprocket wheels 306 in the circumferential direction. The sprocket wheels on both sides 306 is fixedly connected to the output end of the servo motor; wherein, a friction correction frame 303 is provided between the two groups of sprockets 306, and the friction correction frame 303 is in contact with the roller body 302; specifically, when the lotus seeds are arranged to two adjacent groups of roller bodies 302, as the servo motor drives each roller body 302 to transmit, the roller body 302 contacts with the friction correction frame 303, thereby driving the two adjacent groups of roller bodies 302 to rotate in the same direction at the required speed, so that the lotus seeds located between the two adjacent groups of roller bodies 302 roll quickly, thereby realizing the rapid adjustment of the lotus seeds to a state parallel to the axis of the roller body 302, and then horizontal feeding can be realized.

[0066] See also Figure 1-Figure 3 In this embodiment, the color sorting module 106 includes two groups of camera lenses 5 symmetrically arranged in the color sorting box 1, and the two groups of camera lenses 5 are arranged at the conveying end position of the roller conveying module 301. It also includes a good product material port 104 opened at the bottom of the color sorting box 1, and the good product material port 104 is connected to the first discharge pipe 103 at the bottom. A bad product material port 105 is opened on the side of the good product material port 104 away from the roller conveying module 301, and the bad product material port 105 is connected to the second discharge pipe 102, wherein the bottom of the roller conveying module 301 is provided with an air jet mechanism 501 toward the bad product material port 105; specifically, the lotus seeds are conveyed by the rollers. When the conveying module 301 is conveyed to the end, it can fall horizontally under the action of gravity. In the process of falling, the image information of the two ends of the lotus seeds is captured by the camera lenses 5 on both sides, and then the color information of the two ends of the lotus seeds is sent to the controller for comparison. If the color meets the color sorting conditions, the qualified lotus seeds are discharged through the good product material port 104 according to the original motion track. If the color does not meet the color sorting conditions, the controller controls the jet mechanism 501 to spray air to change the original motion track of the unqualified lotus seeds, deviate to a farther distance, so that the unqualified lotus seeds fall to the inferior product material port 105 and are discharged, thereby achieving the effect of lotus seed sorting;

[0067] It should be noted that the camera lens 5 and the jet mechanism 501 of this embodiment are conventional technologies well known to those skilled in the art and will not be described in detail here.

[0068] A color sorting method for a lotus seed color sorter comprises the following steps:

[0069] See also Figure 1-Figure 3 , placing the lotus seeds uniformly in the feed funnel 4;

[0070] The rotating module drives the feed funnel 4 to rotate, and the feed funnel 4 drives the filter plate 6 to rotate synchronously, so that the lotus seeds falling on the filter plate 6 undergo centrifugal motion, and the lotus seeds fall into the vibrating material sorting plate 201;

[0071] The material is discharged to the conveying track 202 through the discharge port of the vibrating material sorting tray 201, and then slides onto the roller conveying module 301 for horizontal conveying;

[0072] When the lotus seeds are transported to the end by the roller transport module 301, they fall horizontally. During the falling process, the camera lenses 5 on both sides capture the image information of both ends of the lotus seeds.

[0073] The color information of both ends of the lotus seeds is sent to the controller for comparison. If the color meets the color sorting conditions, the qualified lotus seeds are discharged through the good product material port 104 according to the original motion trajectory. If the color does not meet the color sorting conditions, the controller controls the jet mechanism 501 to spray air to change the original motion trajectory of the unqualified lotus seeds, deviate to a farther distance, and make the unqualified lotus seeds fall to the inferior product material port 105 and be discharged.
