Description

Technical Field

[0001] This utility model relates to the field of color sorting machine technology, specifically a rice color sorting machine using a photoelectric device. Background Technology

[0002] Color sorters require continuous backlighting to ensure that the camera can stably capture images of the rice falling. However, with prolonged use, the backlighting surface ages, causing changes in the color temperature of the illumination. This color difference in the photograph directly affects the color sorting accuracy of the product.

[0003] For example, a rice color sorter using a photoelectric device, as disclosed in announcement number "CN220126934U," includes a heating assembly comprising a connecting frame fixedly connected to the bottom of a feeding inclined plate, with reinforcing ribs on the surface of the connecting frame. A pressing spring is fixedly connected to the bottom of the inner wall of the connecting frame, and the surface of the pressing spring has friction textures. An electric heating element, made of PTC, is movably connected to one side of the surface of the pressing spring. A lifting handle is fixedly connected to one side of the top of the electric heating element. Through this heating assembly, the device uses the electric heating element to heat and dry the falling rice. The structure is simple, and when the electric heating element is damaged, it can be replaced simply by pulling out the lifting handle.

[0004] When the background light needs to be replaced, the operator needs to turn multiple screws, which takes a long time to complete the disassembly of the background light. At the same time, the heating component of this color sorter is not effective at drying rice that is far from the electric heating element, which can easily cause some rice with high moisture content to enter the color sorter, reducing the color sorting effect. Utility Model Content

[0005] The purpose of this invention is to solve the problems that when the background light needs to be replaced, the operator needs to turn multiple screw rods, which takes a long time to complete the disassembly of the background light. At the same time, the color sorter's heating component has poor drying effect on rice that is far from the electric heating element, which easily leads to some rice with high moisture content entering the color sorter and reducing the color sorting effect. Therefore, this invention proposes a rice color sorter using a photoelectric device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a rice color sorter using photoelectric devices, including a first box and a second box. The second box is fixedly connected to the top of the first box. The first box has multiple fixed structures inside. The second box has a drying mechanism inside. A collection box is slidably connected to the lower inner wall of the first box. A discharge port is fixedly connected to the right side of the first box. An air inlet pipe is fixedly connected to the left side of the first box. The inner walls of both the first and second boxes are fixedly connected to connecting pipes. A door is installed on the front side of the first box.

[0008] Preferably, the second housing is bolted to the cover plate, and feed pipes are fixedly connected to both sides of the cover plate.

[0009] Preferably, the fixing structure includes a vertical rod, with multiple protrusions fixedly connected to the outer side of the vertical rod. Both the protrusions and the outer wall of the vertical rod are inserted into slots. The inner wall of the protrusions is inserted into a slide rod. A spring is sleeved on the outer wall of the slide rod. The two ends of the spring are fixedly connected to a locking block and a fixing block, respectively. Both sides of the slide rod are slidably connected to the fixing block. The inner wall of the locking block is fixedly connected to the slide rod.

[0010] Preferably, a background light and a CCD camera are respectively installed at the upper end of the vertical rod, and the outer wall of the fixing block is fixedly connected to the first box.

[0011] Preferably, the drying mechanism includes a servo motor, a rotating rod is fixedly connected to the end of the output shaft of the servo motor, a spiral heating tube is installed on the outer wall of the rotating rod, a plurality of stirring blades are fixedly connected to the outer side of the rotating rod, and the outer wall of the output shaft of the servo motor is rotatably connected to the cover plate through a bearing.

[0012] Preferably, the end of the servo motor is threadedly connected to the cover plate by bolts, and a heating plate is installed inside the second housing.

[0013] This utility model proposes a rice color sorter using a photoelectric device. Its advantages are as follows: through the cooperation of a fixed block and a fixed structure, a sliding rod is pulled relative to the fixed block while simultaneously compressing a spring. When the sliding rod cannot move, its end moves out of the locking block. Then, the operator removes the corresponding vertical rods of the damaged backlight and CCD camera from the slots on the fixed block. Next, a new vertical rod and locking block are inserted into their corresponding slots. The sliding rod remains taut. When the sliding rod is released, the spring deforms, causing the end of the sliding rod to quickly insert into the groove of the locking block, thus securing the new CCD camera and backlight. This significantly reduces the time required to replace the CCD camera and backlight compared to operators rotating multiple screws.

[0014] Through the cooperation of the cover plate and the drying mechanism, the output shaft of the servo motor rotates, which drives the rotating rod to rotate, thereby driving the stirring blade and the spiral heating tube to rotate. The stirring blade can stir the rice inside the second chamber, so as to achieve a better drying effect for the rice inside the second chamber, which can improve the effect of subsequent color sorting to a certain extent.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] See attached document Figure 1-6 In this embodiment, a rice color sorter using a photoelectric device includes a first box 1 and a second box 9. The second box 9 is fixedly connected to the top of the first box 1. The first box 1 has multiple fixed structures 3 inside. The second box 9 has a drying mechanism 8 inside. A collection box 11 is slidably connected to the lower inner wall of the first box 1. A discharge port 2 is fixedly connected to the right side of the first box 1. An air inlet pipe 10 is fixedly connected to the left side of the first box 1. The inner walls of both the first box 1 and the second box 9 are fixedly connected to a connecting pipe 4. A box door 12 is installed on the front side of the first box 1.

[0024] The second housing 9 is bolted to the cover plate 6. The upper sides of the cover plate 6 are fixedly connected to the feed pipes 5. The upper end of the vertical rod 301 is respectively equipped with a background light 13 and a CCD camera 14. The models of the CCD camera 14 and the background light 13 are selected according to actual needs to meet the work requirements. The outer wall of the fixing block 15 is fixedly connected to the first housing 1.

[0025] The fixed structure 3 includes a vertical rod 301. Multiple protrusions 302 are fixedly connected to the outer side of the vertical rod 301. Both the protrusions 302 and the outer wall of the vertical rod 301 are inserted into the slot 306. The inner wall of the protrusions 302 is inserted into the slide rod 303. A spring 305 is sleeved on the outer wall of the slide rod 303. The two ends of the spring 305 are fixedly connected to the locking block 304 and the fixing block 15, respectively. Both sides of the slide rod 303 are slidably connected to the fixing block 15. The inner wall of the locking block 304 is fixedly connected to the slide rod 303.

[0026] The drying mechanism 8 includes a servo motor 801. A rotating rod 802 is fixedly connected to the end of the output shaft of the servo motor 801. A spiral heating tube 803 is installed on the outer wall of the rotating rod 802. Multiple stirring blades 804 are fixedly connected to the outer side of the rotating rod 802. The outer wall of the output shaft of the servo motor 801 is rotatably connected to the cover plate 6 through a bearing. The end of the servo motor 801 is threadedly connected to the cover plate 6 through bolts. A heating plate 7 is installed inside the second housing 9. The models of the heating plate 7 and the spiral heating tube 803 are selected according to actual needs to meet the working requirements. Both the heating plate 7 and the spiral heating tube 803 are connected to a temperature controller.

[0027] Working principle:

[0028] Using a rice color sorter with photoelectric devices:

[0029] Rice is added into the second chamber 9 through the two feed pipes 5. Then, the electric heating plate 7 and the spiral heating tube 803 are started. The temperature can be controlled by a thermostat. Then, the servo motor 801 is started. The output shaft of the servo motor 801 rotates, which drives the rotating rod 802 to rotate, thereby driving the stirring blade 804 and the spiral heating tube 803 to rotate. The stirring blade 804 can stir the rice inside the second chamber 9, making the rice inside the second chamber 9 drier. To a certain extent, it can improve the effect of subsequent color sorting. The heat generated during drying can be discharged from the feed pipe 5. The spiral heating tube 803 can be powered by a battery. The battery is installed on the outer wall of the rotating rod 802, located on the outside of the equipment, for easy replacement and switching.

[0030] To further explain: the spiral heating element 803 is electrically connected to the thermostat, battery and switch on the battery via wires. The wires pass through the interior of the rotating rod 802 and then exit from the top of the rotating rod 802 to be electrically connected to the motor. In this way, when the spiral heating element 803 rotates, the wires and battery rotate with the rotating rod 802, and there will be no wire tangling.

[0031] After the rice is dried, all drive power is turned off, CCD camera 14 and background light 13 are turned on, and then the solenoid valve on the connecting pipe 4 is opened to allow the dried rice in the second chamber 9 to enter the first chamber 1. When the rice passes the background light 13 and CCD camera 14, the background light 13 illuminates the falling rice, and the two symmetrical CCD cameras 14 take pictures and analyze the falling rice. If the rice is good, it falls directly into the collection box 11 below. If the rice is bad, high-pressure gas is sprayed out from the air inlet pipe 10 (the left side of the air inlet pipe 10 is connected to the external air compressor) to blow the bad rice out from the discharge port 2. The external air compressor, CCD camera 14 and background light 13 can be connected to the PLC controller and turned on and off in a certain sequence through programming and other operations.

[0032] When the backlight 13 and CCD camera 14 are damaged, the equipment stops working. The operator opens the door 12 and pulls the slide bar 303 relative to each other, while compressing the spring 305. When the slide bar 303 cannot move, the end of the slide bar 303 is removed from the locking block 304. Then, the operator removes the vertical rod 301 corresponding to the damaged backlight 13 and CCD camera 14 from the slot 306 on the fixing block 15. Then, the new vertical rod 301 and locking block 304 (the groove on the locking block 304 fits into the slot) are installed. The slide bar 301 (located on one side of the slide bar 303) is inserted into the corresponding slot 306. The slide bar 301 is always in a taut state. Then the slide bar 301 is released, and the spring 305 deforms (a spring damper can be installed at the end of the spring when there are special requirements), so that the end of the slide bar 301 is quickly inserted into the groove of the locking block 304, thereby fixing the new CCD camera 14 and the backlight 13. This reduces the time required to replace the CCD camera 14 and the backlight 13 compared to the operator turning multiple screws.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
