Description

Technical Field

[0001] This utility model belongs to the field of ginseng classification technology, and in particular relates to a rotating platform for ginseng classification based on visual recognition. Background Technology

[0002] Classifying ginseng has significant practical implications: on the one hand, due to differences in growth environment, cultivation methods, and growth years, the content of effective components, medicinal value, and market price of ginseng vary significantly. Classification can achieve precise quality definition and protect consumer rights. On the other hand, scientific classification can regulate market circulation order, provide standardized basis for medicinal material procurement, pharmaceutical research and development, and clinical application, and promote the standardized development of the ginseng industry.

[0003] Ginseng can be classified into wild ginseng, forest ginseng, and cultivated ginseng according to its growth method. Wild ginseng is rare and precious, while cultivated ginseng has a higher yield due to artificial cultivation. Different types of ginseng have different morphological characteristics. Currently, the mainstream ginseng classification equipment on the market uses a recognition camera to identify the morphological characteristics of ginseng for classification. However, the following problems still exist in its use:

[0004] 1. Generally, two recognition cameras are set up to take pictures of the head and tail of the ginseng for recognition. Before the ginseng is recognized, each ginseng needs to be placed into the feeding box by hand. Then the feeding box moves under the recognition camera and the recognition camera takes pictures of the ginseng for recognition. Because the ginseng is placed manually, the position of the ginseng is difficult to standardize, and the recognition camera may not be able to accurately observe the characteristics of the ginseng, resulting in poor recognition results. If multiple recognition cameras are set up to take pictures from multiple angles, although the recognition accuracy will be improved, the cost will increase.

[0005] 2. When sorting and unloading the ginseng after identification, the feeding box is flipped over to pour the ginseng directly into the feeding box and enters the ginseng collection device from the lower end of the feeding box. At this time, the soil adhering to the ginseng also enters the collection device, which increases the workload when handling the ginseng later.

[0006] 3. After the feeding box flips over and dumps out the ginseng, it cannot automatically reset itself. This means that when putting in ginseng later, the feeding box needs to be pushed to reset itself, which increases the workload of the workers.

[0007] To address these issues, we provide a visual recognition-based rotating platform for ginseng classification. Utility Model Content

[0008] The purpose of this utility model is to provide a rotating platform for ginseng classification based on visual recognition. By setting up a metal rod, support base, strong magnet, rotating rod, recognition camera, feeding box and sieve holes, it solves the problems of low classification accuracy when classifying ginseng based on visual recognition, increased handling burden caused by soil adhering to the ginseng entering the collection device, and the inability of the feeding box to reset itself.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model is a rotating platform for ginseng classification based on visual recognition, including a base, a ring gear, a feeding box, a recognition component, and a feeding box. The top of the base has a through-hole groove, and the ring gear is rotatably connected to the base in the groove. The top of the ring gear has feeding boxes arranged in a ring array. The base is fixedly connected to two symmetrically arranged ear plates. The recognition component includes an inverted U-shaped support frame. One vertical part of the support frame is fixedly connected to the ear plate, and the other vertical part of the support frame is fixedly connected to the base located on the periphery of the ring gear. The bottom of the horizontal part of the support frame is rotatably connected to a rotating rod. Both ends of the bottom of the rotating rod are fixedly connected to an inclined recognition camera. The lenses of the recognition cameras all point to the feeding boxes located below the support frame.

[0011] One side of the ear plate is the feeding area, and the other side is the sorting and unloading area. Workers put ginseng into the feeding box one by one in the feeding area. The ring gear rotates and drives the feeding box to move. After the feeding box moves to the support frame, it stops for a period of time. During the pause, two recognition cameras first take pictures of the head and tail of the ginseng. Then the rotating rod rotates 90° and the recognition camera takes pictures of both sides of the ginseng. The ginseng is identified based on the information from the two pictures. Then the feeding box continues to move to the unloading area for sorting and unloading.

[0012] The base is also fixedly connected to three inclined feeding boxes arranged in a circular array. All three feeding boxes are located on the same side of ear plate one and ear plate two. Screen holes are opened on the lower inclined surface of the feeding boxes.

[0013] The feeding box is located in the feeding area, and the other side is the feeding area. Three types of ginseng collection devices are set at the lower end of the three feeding boxes. Based on the results of two photo recognitions, the feeding box moves above the corresponding feeding box and flips over to pour the ginseng into the corresponding feeding box. The ginseng moves along the bottom of the feeding box to the corresponding ginseng collection device. During the movement of the ginseng, the sticky soil is shaken off and falls into the soil collection device through the sieve holes.

[0014] Furthermore, a cavity is provided inside the ear plate, the cavity is connected to the rotating groove, a drive gear is provided inside the cavity and is rotatably connected to the ear plate, the drive gear meshes with the ring gear, a motor is fixedly connected to the bottom of the ear plate, and the output shaft of the motor is connected to the end of the drive gear near it in a transmission connection.

[0015] When motor one is started, the output shaft of motor one rotates periodically, which drives the drive gear to rotate periodically, thereby realizing the rotation and stopping of the ring gear, and thus realizing the rotation and stopping of the material conveying box.

[0016] Furthermore, both sides of the feeding box are rotatably connected to support rods that are fixedly connected to the ring gear. A limiting plate is fixedly connected between the two support rods. The bottom of the feeding box, located at the end of the support rod near the center of the base, is provided with an inverted U-shaped support seat that is fixedly connected to the ring gear. In the feeding state, the bottom of the feeding box is in contact with the horizontal part of the support seat. The height of the limiting plate is lower than the height of the horizontal part of the support seat. A metal strip is fixedly connected to the bottom of the feeding box near the opening. An inverted L-shaped connecting rod is fixedly connected to the end of the feeding box near the center of the base. A metal rod is fixedly connected to the bottom of the vertical part of the connecting rod.

[0017] During material feeding, the support base provides support for the feeding box to prevent it from rotating. When the feeding box moves to the top of the feeding box corresponding to the ginseng inside, it rotates to release the ginseng. Due to the setting of the limiting plate, the feeding box will not rotate excessively and rub against the base.

[0018] Furthermore, a second motor is fixedly connected to the top of the horizontal part of the support frame, and the output shaft of the second motor is connected to the top of the rotating rod for transmission; when the second motor is started, the output shaft of the second motor rotates, which drives the rotating rod to rotate, thereby driving the recognition camera to rotate.

[0019] Furthermore, photoelectric sensor switches are fixedly connected to the top of the base near the material box. The photoelectric sensor switches are located on the side of the material box near the ear plate two. Electromagnets are fixedly connected between the two side plates of the material box near the higher end.

[0020] After the camera identifies the ginseng, the control system sends a signal to the corresponding photoelectric sensor switch. When the feeding box moves above the photoelectric sensor switch, the photoelectric sensor switch controls the electromagnet to be energized. The electromagnet generates a force on the metal strip, causing the feeding box to rotate and pour the ginseng from the feeding box into the unloading box.

[0021] Furthermore, a strong magnet is fixedly connected to the top of the base located inside the circumference of the ring gear near the ear plate.

[0022] After the material is fed, the feeding box continues to move. When it moves to the vicinity of the strong magnet, the strong magnet attracts the metal rod, which pulls the feeding box to rotate. With the support of the support base, the feeding box completes its horizontal reset.

[0023] Furthermore, a support leg is fixedly connected to the bottom of the base; the support leg provides support for the base.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model solves the problem of low recognition accuracy by setting up a rotating rod and recognition cameras; the feeding box moves to the space between the two recognition cameras and pauses for a period of time before continuing to move. During the pause of the feeding box, the two recognition cameras first take pictures of the head and tail of the ginseng respectively. Then the rotating rod rotates 90°, driving the two recognition cameras to rotate 90° and take pictures of both sides of the ginseng respectively. The ginseng is recognized based on the results of the two pictures, thereby improving the recognition accuracy.

[0026] 2. This utility model solves the problem of soil adhering to ginseng entering the collection device by setting up a feeding box and sieve holes; when the ginseng moves at the bottom of the feeding box, the adhering soil is shaken off, and this soil falls into the soil collection device below the feeding box through the sieve holes, thereby reducing the burden of handling.

[0027] 3. This utility model solves the problem of the feeding box being unable to reset itself by setting a metal rod, a support base, and a strong magnet. After the ginseng is poured out, the feeding box continues to move with the rotation of the ring gear. When the feeding box moves to the vicinity of the strong magnet, the metal rod is attracted by the strong magnet and pulls the feeding box to rotate. Due to the support of the support base, the feeding box rotates to a horizontal state, thus achieving the purpose of the feeding box resetting itself. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Specific Implementation Example 1

[0040] Please see Figure 1-7 This utility model is a rotating platform for ginseng classification based on visual recognition, including a base 1, a ring gear 2, a feeding box 3, a recognition component 4, and a feeding box 5. A rotating groove 102 is formed through the top of the base 1, and a ring gear 2 rotatably connected to the base 1 is disposed within the groove 102. Feeding boxes 3 arranged in a ring array are disposed at the top of the ring gear 2. Symmetrically arranged ear plates 103 and 104 are fixedly connected to the periphery of the base 1. The recognition component 4 includes an inverted U-shaped support frame 401, one of the vertical parts of which... The other vertical part of the support frame 401 is fixedly connected to the ear plate 2 104 and the base 1 located on the side of the ring gear 2. The bottom of the horizontal part of the support frame 401 is rotatably connected to the rotating rod 402. Both ends of the bottom of the rotating rod 402 are fixedly connected to the inclined recognition camera 403. The lenses of the recognition camera 403 all point to the material box 3 located below the support frame 401. Three inclined feeding boxes 5 are also fixedly connected to the side of the base 1 in a ring array. The three feeding boxes 5 are all located on the same side of the ear plate 103 and the ear plate 2 104.

[0041] The base 1 provides a workspace for ginseng sorting. The feeding box 5 is located on one side as the feeding area and on the other side as the feeding area. Workers place ginseng into the feeding box 3 one by one in the feeding area. The ring gear 2 rotates, driving the feeding box 3 to move. After the feeding box 3 moves to the support frame 401, it stops for a period of time. During the stop, two recognition cameras 403 first take pictures of the head and tail of the ginseng. Then, the rotating rod 402 rotates 90°, and the recognition camera 403 takes pictures of both sides of the ginseng. The ginseng is identified based on the feature information obtained from the two pictures. Then, the feeding box 3 continues to move to the feeding area for sorting and feeding. Three types of ginseng collection devices are set at the lower end of the three feeding boxes 5 respectively. Based on the results of the two picture recognitions, the feeding box 3 moves to the top of the corresponding feeding box 5 and flips over, so that the ginseng can be poured into the corresponding feeding box 5 and moved along the bottom of the feeding box 5 to the corresponding ginseng collection device.

[0042] Among them, such as Figure 2 , Figure 3 As shown, a cavity 105 is provided inside the ear plate 103. The cavity 105 is connected to the rotating groove 102. A drive gear 201 that is rotatably connected to the ear plate 103 is provided in the cavity 105. The drive gear 201 meshes with the ring gear 2. A motor 202 is fixedly connected to the bottom of the ear plate 103. The output shaft of the motor 202 is connected to the end of the drive gear 201 that is close to it.

[0043] When motor 202 is started, the output shaft of motor 202 rotates periodically, which drives the drive gear 201 to rotate periodically, thereby realizing the rotation and stopping of the ring gear 2, and thus realizing the movement and stopping of the material box 3.

[0044] Among them, such as Figure 4 , Figure 5 As shown, both sides of the feeding box 3 are rotatably connected to support rods 304 that are fixedly connected to the ring gear 2. A limiting plate 305 is fixedly connected between the two support rods 304. The bottom of the feeding box 3, located at the end of the support rod 304 near the center of the base 1, is provided with an inverted U-shaped support seat 306 that is fixedly connected to the ring gear 2. In the feeding state, the bottom of the feeding box 3 is in contact with the horizontal part of the support seat 306, and the height of the limiting plate 305 is lower than the height of the horizontal part of the support seat 306.

[0045] When conveying ginseng, the support base 306 provides support for the conveying box 3 to prevent the conveying box 3 from rotating. When the conveying box 3 moves to the top of the feeding box 5 corresponding to the ginseng inside, it rotates to release the ginseng. Due to the setting of the limiting plate 305, the conveying box 3 will not rotate excessively and rub against the base 1.

[0046] Among them, such as Figure 6As shown, a second motor 404 is fixedly connected to the top of the horizontal part of the support frame 401, and the output shaft of the second motor 404 is connected to the top of the rotating rod 402 through a transmission connection.

[0047] When motor 404 is started, the output shaft of motor 404 rotates, which drives the rotating rod 402 to rotate, and then drives the recognition camera 403 to rotate, taking pictures of the head, tail and sides of the ginseng for recognition.

[0048] Among them, such as Figure 1 As shown, a support leg 101 is fixedly connected to the bottom of the base 1; the support leg 101 provides support for the base 1.

[0049] The working principle of this embodiment is as follows: When sorting ginseng, motor 202 is started. The output shaft of motor 202 rotates periodically, driving the drive gear 201 to rotate periodically, causing the ring gear 2 to rotate periodically. The feeding box 3 moves a certain distance and then pauses for a period of time, then continues to move a certain distance, and so on. The side where the unloading box 5 is located is the unloading area, and the other side is the loading area. When the feeding box 3 pauses, the worker puts the ginseng into the feeding box 3 one by one in the loading area. The feeding box 3 containing ginseng moves to the support frame 401 and pauses for a period of time. The two recognition cameras 403 first scan the ginseng. The head and tail are photographed, then motor 2 404 is started. The output shaft of motor 2 404 rotates 90°, driving the rotating rod 402 to rotate 90°. The recognition camera 403 also rotates 90° to take pictures of both sides of the ginseng. The ginseng is identified based on the feature information obtained from the two photos. Then the feeding box 3 continues to move to the unloading area. Three types of ginseng collection devices are set at the lower end of the three unloading boxes 5 respectively. Based on the results of the two photo recognitions, the feeding box 3 moves to the top of the corresponding unloading box 5 and flips over, so that the ginseng can be poured into the corresponding unloading box 5 and moved along the bottom of the unloading box 5 into the ginseng collection device. Specific Implementation Example 2

[0051] Please see Figure 5 , Figure 7 Based on the first specific embodiment, a sieve hole 503 is provided on the lower inclined surface of the feeding box 5. A metal strip 301 is fixedly connected to the bottom of the feeding box 3 near the opening. An inverted L-shaped connecting rod 302 is fixedly connected to one end of the feeding box 3 near the center of the base 1. A metal rod 303 is fixedly connected to the bottom of the vertical part of the connecting rod 302. A photoelectric sensor switch 501 is fixedly connected to the top of the base 1 near the feeding box 5. The photoelectric sensor switch 501 is located on the side of the feeding box 5 near the ear plate 104. An electromagnet 502 is fixedly connected between the two side plates of the feeding box 5 near the higher end.

[0052] Among them, such as Figure 1As shown, a powerful magnet 6 is fixedly connected to the top of the base 1 located inside the circumference of the ring gear 2, near the ear plate 103.

[0053] The working principle of this embodiment is as follows: After the recognition camera 403 recognizes the ginseng, it sends a signal to the corresponding photoelectric sensor switch 501 through the control system. When the feeding box 3 moves above the photoelectric sensor switch 501, the photoelectric sensor switch 501 controls the electromagnet 502 to be energized. The electromagnet 502 generates a magnetic force on the metal strip 301, causing the feeding box 3 to rotate and pour the ginseng from the feeding box 3 into the unloading box 5. Due to the obstruction of the limiting plate 305, the feeding box 3 will not rotate excessively. The feeding box 3 and the limiting plate 305 are in contact. The vibration generated during the collision of 5 shakes off the soil on the ginseng. The ginseng moves along the bottom of the feeding box 5 to the corresponding ginseng collection device. During the movement of the ginseng in the feeding box 5, the soil adhering to it is further shaken off. This soil falls into the soil collection device through the screen hole 503. After the feeding is completed, the feeding box 3 continues to move. When it moves to the vicinity of the strong magnet 6, the strong magnet 6 attracts the metal rod 303. The metal rod 303 pulls the feeding box 3 to rotate. With the support of the support seat 306, the feeding box 3 completes the horizontal reset.

[0054] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
