Description

Technical Field

[0001] The utility model relates to the technical field of grain processing equipment, in particular to a color sorter. Background Art

[0002] A color sorter is a device that uses photoelectric detection technology to automatically sort out different-colored particles from granular materials based on the differences in the optical properties of the materials. The color sorter uses sensing equipment to detect the color of the falling grains and uploads the detected color signal to the processing equipment. Once it finds that the color is different from that of ordinary grains, the processing equipment controls the jet equipment to spray gas to blow away the inferior grains of different colors, thereby achieving color sorting.

[0003] At present, the amount of grain fed into the color sorter is not stable enough. A small amount will not affect the color sorting. However, when a large amount of grain is fed at one time, the overly concentrated grains will block each other, affecting the resolution of the camera. As a result, some inferior grains are hidden in the normal grains and are not captured by the camera, resulting in incomplete color sorting. Rework is required, which reduces the efficiency of color sorting. Utility Model Content

[0027] Through the above-mentioned structural setting, the grains to be color-sorted are poured into the feed chamber 2, and the reduction motor 31 is started at the same time. The reduction motor 31 drives the limiting blade 33 to rotate through the rotating rod 32, and the grains slowly fall onto the conveying plate 4 as the limiting blade 33 rotates.

[0028] Reference Figure 2-4 , wherein a plurality of diverter grooves 41 are equidistantly provided on the conveying plate 4, a diverter plate 42 is fixedly installed on one side toward which the openings of the plurality of diverter grooves 41 face, and the top of the diverter plate 42 is in an open shape;

[0029] With the above-mentioned structural arrangement, when grains fall down, they fall onto the diverter plate 42 and then slide down along the diverter slot 41 to be color sorted and processed, thereby limiting the amount of grains that fall within a certain period of time.

[0030] Reference Figure 2-4 , wherein the sliding assembly 5 comprises an electric slide rail 51, the electric slide rail 51 is fixedly installed at the top opening of the diverter plate 42, an electric slider 52 is slidably installed on the electric slide rail 51, and a flattening plate 6 is fixedly installed on the electric slider 52;

[0031] Through the above-mentioned structural setting, when the grain falls into the opening of the diverter plate 42, the electric slide rail 51 is started, and the electric slide rail 51 drives the flattening plate 6 to move back and forth through the electric slider 52, pushing the accumulated grain into different diverter grooves 41, and making the grain slide evenly from different diverter grooves 41, while avoiding the accumulation of grain.

[0032] Reference Figure 2-3 , wherein the vibration assembly 8 includes a mounting frame 81, the mounting frame 81 is fixedly mounted on the inner wall of the box body 1, a plurality of springs 82 are symmetrically mounted on the top of the mounting frame 81, the tops of the plurality of springs 82 are all connected to the screen 9, and a vibration motor 83 is fixedly mounted on the bottom of the screen 9;

[0033] With the above-mentioned structural arrangement, when the color-selected grains fall onto the screen 9 , the vibration motor 83 is started, and the vibration motor 83 sieves the broken rice wrapped inside the rice from the screen 9 through vibration, so that the broken rice falls into the broken rice chamber 10 .

[0034] Reference Figure 2-3 , wherein the mesh of the screen 9 is smaller than the size of the whole grain and larger than the size of the broken rice, and a baffle is fixedly installed on the screen 9 except for one side facing the good product cavity 11;

[0036] Reference Figure 2 , wherein an optical detection component 13 is disposed at the bottom of the conveying plate 4, and an injection separation component 14 is disposed at the bottom of the optical detection component 13, and both the optical detection component 13 and the injection separation component 14 are electrically connected to the control center.

[0037] Through the above-mentioned structural setting, the optical detection component 13 is used to continuously scan the material to be processed, capture the image of the material, and transmit it to the control center for processing. The control center will process and analyze the received material image. It will judge the quality and grade of each material according to the preset color sorting standard. When defective or non-compliant materials are found, the system will make corresponding judgments. According to the analysis results of the control center, the injection separation component 14 will classify and sort each material. The sorting system will use a gas injector to exclude non-compliant materials from the color sorting area, and qualified materials will fall into the qualified material port along the set route.

[0038] Working principle:

[0039] The first step to implement the innovation point:

[0040] Step 1: Pour the grain into the feed chamber 2 and start the reduction motor 31 at the same time. The reduction motor 31 drives the limiting blade 33 to rotate through the rotating rod 32. The grain is gradually transferred out of the feed hopper 2 along with the rotation of the limiting blade 33, and then slides into the opening of the diverter plate 42. Then, the electric slide rail 51 is started. The electric slide rail 51 drives the flattening plate 6 to move back and forth through the electric slider 52, pushing the accumulated grain into different diverter grooves 41, so that the grain slides evenly along the different diverter grooves 41 to avoid grain accumulation.

[0041] Step 2: The optical detection component 13 and the jet separation component 14 cooperate with each other to perform color sorting on the fallen grains. The grains that fail the color sorting fall into the waste chamber 12, and the grains that pass the color sorting fall onto the screen 9. Then the vibration motor 83 is started. The vibration motor 83 vibrates to sieve the broken rice wrapped in the rice from the screen 9, so that the broken rice falls into the broken rice chamber 10. The intact rice moves toward the empty side of the screen 9 with the vibration, and finally falls into the good product chamber 11 to complete the rice separation. Finally, the sorted rice can be taken out and collected.
