DETAILED DESCRIPTION
[0025] The following is combined with Figure 1-2 This application is described in further detail.
[0026] In the present disclosure, unless otherwise stated, directional words such as "inside" and "outside" refer to the inside and outside of the outline of a component or structure itself; Figure 1 The X direction in represents the first direction; Figure 1 The Y direction in the figure represents the second direction. Unless otherwise specified, the terms "first, second" and the like are used to distinguish one element from another element and do not have order or importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.
[0027] The embodiment of the present application discloses a melon seed selection device.
[0028] like Figure 1 As shown, the melon seed selection equipment includes a screening device and a color sorting device, wherein the screening device includes a screening bin 1, a first screen 2 and a second screen 3 which are arranged in the screening bin 1 in sequence from top to bottom along the vertical direction, and a vibration mechanism 4, the pores of the first screen 2 are larger than the pores of the second screen 3, and the vibration mechanism 4 is connected to the screening bin 1, and is used to drive the screening bin 1 to vibrate, so that the material entering the screening bin 1 can be screened and filtered through the first screen 2 and the second screen 3.
[0029] The vibrating mechanism 4 is used to drive the screening bin 1 to vibrate, so that the material entering the screening bin 1 can be screened and filtered through the first screen 2 and the second screen 3. Since the pores of the first screen 2 are larger than the pores of the second screen 3, impurities with larger particle sizes cannot pass through the first screen 2, and only impurities with smaller particle sizes can pass through the second screen 3. The material after multi-stage screening is retained on the screen surface of the second screen 3, thereby realizing multi-stage screening of the material. Among them, the vibrating mechanism 4 can be a three-phase asynchronous vibration motor or an exciter, and its function is to drive the screening bin 1 to vibrate, and this application does not impose any restrictions on this.
[0030] like Figure 2 As shown, the first screen 2 and the second screen 3 separate the screening bin 1 into a first cavity 101, a second cavity 102 and a third cavity 103 which are arranged from top to bottom, a feed port 104 is formed on the top of the screening bin 1, a first discharge port 105, a second discharge port 106 and a third discharge port 107 are formed on the side wall of the screening bin 1, the feed port 104 is connected to the first cavity 101, the first discharge port 105 is connected to the first cavity 101; the second discharge port 106 is connected to the second cavity 102; the third discharge port 107 is connected to the third cavity 103.
[0031] The material slowly enters the screening bin 1 through the feed port 104 of the screening bin 1. The screening bin 1 starts to vibrate under the action of the vibration mechanism 4. Impurities with larger particle sizes are retained in the first cavity 101 under the action of the first screen 2, and the rest fall into the second cavity 102; then melon seeds and impurities with a particle size similar to that of melon seeds are retained in the second cavity 102 under the action of the second screen 3; finally, impurities and dust with smaller particle sizes all enter the third cavity 103 under the action of the second screen 3, thereby realizing graded screening.
[0032] like Figure 2 As shown, in order to facilitate the materials after multi-stage screening to leave the screening bin 1, the first screen 2 is tilted downward and points to the direction of the first discharge port 105, the second screen 3 is tilted downward and points to the direction of the second discharge port 106, and the bottom wall of the screening bin 1 can also be tilted and points to the direction of the third discharge port 107. The tilted screen can make the filtered materials left in the screening bin 1 move toward the discharge port while the screening bin 1 is vibrating and screening, and finally gradually discharged from the discharge port during the screening process, avoiding the accumulation of filtered materials. At the same time, it also reduces the workload of the staff in the later cleaning.
[0033] like Figure 1 and Figure 2 As shown, in order to improve the screening effect and facilitate the processing of the filtrate, the first discharge port 105 connected to the first cavity 101 for discharging impurities with larger particle sizes and the third discharge port 107 connected to the third cavity 103 for discharging impurities with smaller particle sizes are arranged on the same side of the screening bin 1, and the second discharge port 106 connected to the second cavity 102 for discharging melon seeds and impurities with particle sizes similar to melon seeds is arranged on the other side of the screening bin 1 opposite to the first discharge port 105. The first discharge port 105 and the third discharge port 107 located on the same side both discharge impurities, and in the subsequent processing, the staff can process two impurities of different particle sizes together, and the second discharge port 106 located on the opposite side cooperates with the color sorting device.
[0034] like Figure 1 and Figure 2 As shown, the screening device further includes a frame 5, and the screening bin 1 is connected to the frame 5 via an elastic connector, which can effectively reduce the noise generated by the vibration mechanism 4 during use, and at the same time reduce the damage to the screening bin 1 caused by collision. In this embodiment, the elastic member 6 is configured as a plurality of springs. In addition, the elastic member 6 can also be configured as a polyurethane elastic column, the purpose of which is to enable the screening bin 1 to be elastically connected to the frame 5, and the present disclosure does not impose any specific restrictions on this.
[0035] like Figure 1As shown, the color sorting device in the melon seed selection equipment includes a slide 7, an identification mechanism and a color sorting bin 8. The slide 7 is used to receive the melon seeds and impurities with a particle size similar to the melon seeds after being screened and filtered by the screening device. The color sorting bin 8 is arranged at the discharge end of the slide 7. A push plate 9 is arranged in the color sorting bin 8. The push plate 9 can be reciprocated along a first direction perpendicular to its own plate surface and is slidably connected to the color sorting bin 8. The two side walls of the color sorting bin 8 opposite to each other along the first direction are respectively provided with a melon seed outlet 801 and a melon peel outlet 802. A driving member 10 is arranged at the color sorting bin 8. The driving member 10 is connected to the push plate 9 to drive the push plate 9 to reciprocate along the first direction. The identification mechanism is used to detect the material on the slide 7 and is connected to the driving member 10 signal. When the identification mechanism detects that a melon rind has passed through the slide 7, the driving member 10 controls the push plate 9 to move toward the melon seed outlet 801 until the push plate 9 is close to the melon seed outlet 801. On the contrary, when the identification mechanism detects that no melon rind has passed through the slide 7, the driving member 10 controls the push plate 9 to move toward the melon rind outlet 802 and close to the melon rind outlet 802.
[0036] The identification structure is used to detect the material at the slide 7. When the identification mechanism detects that the melon rind passes through the slide 7, the push plate 9 is controlled by the driving member 10 to move toward the melon seed outlet 801 until the push plate 9 is close to the melon seed outlet 801, and the melon seeds are pushed out from the melon seed outlet 801, so that the melon rind passes through the slide 7 and falls into the color sorting bin 8 on the side of the push plate 9 close to the melon rind outlet 802; when the identification mechanism detects that no melon rind passes through the slide 7, the push plate 9 is controlled by the driving member 10 to move toward the melon rind outlet 802 until the push plate 9 is close to the melon rind outlet 802, and the melon rind is pushed out from the melon rind outlet 802, so that the melon seeds fall from the slide 7 into the color sorting bin 8 on the side of the push plate 9 close to the melon seed outlet 801, thereby realizing the automatic removal of the melon rind and improving the production efficiency.
[0037] like Figure 1 and Figure 2 As shown, in order to improve the cleanliness of the melon seeds leaving the melon seed outlet 801 and the melon rind leaving the melon rind outlet 802, dustproof plates 806 may be provided at the melon seed outlet 801 and the melon rind outlet 802. In order to perform subsequent processing on the melon seeds leaving the melon seed outlet 801 and the melon rind leaving the melon rind outlet 802, the staff may set a collection box or a conveyor belt at the melon seed outlet 801 and the melon rind outlet 802, and the present application does not impose any limitation on this.
[0038] like Figure 1 and Figure 2As shown, the driving member 10 includes an electric push rod, which is arranged along the first direction, the body of the electric push rod is fixedly connected to the color sorting bin 8, and the output end of the electric push rod penetrates the side wall of the color sorting bin 8 and is connected to the push plate 9, so that the electric push rod can drive the push plate 9 to reciprocate along the first direction. In order to improve the stability of the electric push rod, a bearing frame 803 may be further provided on one side of the color sorting bin 8 close to the electric push rod, and the body of the electric push rod is connected to the color sorting bin 8 through the bearing frame 803.
[0039] like Figure 1 and Figure 2 As shown, the identification mechanism includes a control component and a camera 11 . The shooting direction of the camera 11 is perpendicular to the inclined surface of the slide 7 and faces the inclined surface of the slide 7 . The control component is signal-connected to the camera 11 and the driving member 10 at the same time.
[0040] The camera 11 is used to collect images at the inclined surface of the slide 7 and send the image data to the control component. The image recognition function integrated in the control component performs image recognition, distinguishes the melon seeds and melon rinds by color, makes a judgment, and sends a signal to control the driving member 10. In order to improve the accuracy of recognition, an auxiliary lighting component can be set on one side of the camera 11, and the inclined surface of the slide 7 can also be dyed to make the color of the inclined surface of the slide 7 and the melon seeds and melon rinds have obvious differences.
[0041] like Figure 1 and Figure 2 As shown, the slide 7 is arranged along the first direction, the slide 7 is arranged at the second discharge port 106 and is fixedly connected to the screening bin 1, the feed end of the slide 7 cooperates with the lower end of the second screen 3, and a plurality of partition plates 804 are arranged at equal intervals in the color sorting bin 8 along the second direction perpendicular to the first direction. The partition plates 804 divide the color sorting bin 8 into a plurality of sorting bins 805, and each sorting bin 805 is connected to the melon seed outlet 801 and the melon peel outlet 802. There are a plurality of push plates 9 and electric push rods, and the number of push plates 9 and electric push rods is the same as the number of sorting bins 805, and each sorting bin 805 is provided with a push plate 9, and the push plates 9 correspond to the electric push rods one by one.
[0042] The color sorting bin 8 can be divided into a plurality of sorting bins 805 by using the partition plate 804. The slideway 7 arranged along the first direction can make the material sliding down the slideway 7 enter different sorting bins 805 respectively along the width direction of the slideway 7, so that the identification mechanism can divide the slideway 7 into a plurality of blocks corresponding to the sorting bins 805 along its width direction, thereby realizing separate control of the push plates 9 in the sorting bins 805. That is, when the identification mechanism detects that a melon rind has passed through a certain block of the slideway 7, the push plate 9 of the corresponding sorting bin 805 can be controlled to separate the melon rind from the melon seeds, thereby reducing the melon seeds discharged from the melon rind outlet 802 during the color sorting process and avoiding waste.
[0043] like Figure 1 As shown, fans 12 are provided on both sides of the slide 7, and the fans 12 are connected to the identification mechanism signal. The fans 12 are used to blow air toward the inclined surface of the slide 7 along the second direction.
[0044] When the melon rind falls from the slide 7 and the identification mechanism detects that no melon rind has passed through a certain area, it is inevitable that some melon seeds will fall with the melon rind because the process from the control component issuing the command to the driver 10 driving the push plate 9 into position requires a certain execution time. Therefore, when the identification mechanism detects that melon rind has passed through a certain block of the slide 7, the fan 12 close to the block is controlled to blow air toward the inclined surface of the slide 7 along the second direction. Since the weight of the melon rind is different from that of the melon seeds, the friction between the melon rind and the inclined surface of the slide 7 is also different, and the displacement generated by the fan 12 is also different, so that the fan 12 can blow the melon seeds to other blocks, so that the melon rind remains in the current block, thereby reducing the melon seeds discharged from the melon rind outlet 802 during the color sorting process and avoiding waste.
[0045] The implementation principle of a melon seed selection device in the embodiment of the present application is as follows: The vibration mechanism 4 is turned on, and the screening bin 1 starts to vibrate under the action of the vibration mechanism 4, and the melon seeds material to be processed is slowly poured into the screening bin 1 through the feed port 104 of the screening bin 1, wherein impurities with larger particle sizes are retained in the first cavity 101 under the action of the first screen 2, and leave the screening bin 1 from the first discharge port 105 along the screen surface of the first screen 2, and the rest fall into the second cavity 102; then the melon seeds and impurities with a particle size similar to that of the melon seeds are retained in the second cavity 102 under the action of the second screen 3, and leave the screening bin 1 from the second discharge port 106 along the screen surface of the second screen 3; finally, impurities and dust with smaller particle sizes all enter the third cavity 103 under the action of the second screen 3, and leave the screening bin 1 from the third discharge port 107 along the bottom wall of the screening bin 1, thereby realizing graded screening.
[0046] The melon seeds and impurities with a particle size similar to that of the melon seeds that have been screened and filtered by the screening device are transported to the slide 7 of the color sorting device from the second discharge port 106. The color sorting bin 8 can be divided into multiple sorting bins 805 by using the partition plate 804. The slide 7 arranged along the first direction can allow the materials sliding down the slide 7 to enter different sorting bins 805 along the width direction of the slide 7, respectively, so that the identification mechanism can divide the slide 7 into multiple blocks corresponding to the sorting bins 805 along its width direction. When the identification mechanism detects that a melon peel has passed through a block of the slide 7, the push plate 9 in the corresponding sorting bin 805 is controlled by the driving member 10 to move toward the melon seed outlet 801 until the push plate 9 is close to the melon seed outlet 801. Melon seeds are pushed out from the melon seed outlet 801, so that the melon rinds fall into the side of the push plate 9 in the sorting bin 805 close to the melon rind outlet 802 through the slide 7; when the identification mechanism detects that no melon rinds pass through a certain block of the slide 7, the push plate 9 of the corresponding sorting bin 805 is controlled by the driving member 10 to move toward the melon rind outlet 802 until the push plate 9 is close to the melon rind outlet 802, and the melon rinds are pushed out from the melon rind outlet 802, so that the melon seeds fall from the slide 7 into the side of the push plate 9 in the sorting bin 805 close to the melon seed outlet 801, thereby realizing the automatic removal of the melon rinds and improving production efficiency.
[0047] At the same time, when the identification mechanism detects that melon rind has passed through a certain block of the slide 7, the fan 12 close to the block is controlled to blow air toward the inclined surface of the slide 7 along the second direction. Since the weight of the melon rind is different from that of the melon seeds, the friction between them and the inclined surface of the slide 7 is also different, and the displacement generated by the fan 12 is also different, so that the fan 12 can blow the melon seeds to other blocks and keep the melon rind in the current block, thereby reducing the melon seeds discharged from the melon rind outlet 802 during the color sorting process and avoiding waste.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
