Technical Field
[0001] This utility model relates to the field of color sorters, and more specifically, to a new type of color sorter for rice processing. Background Technology
[0002] The color sorting process in rice processing involves using a color sorter to select materials in rice that fall within a specified color range. The color sorting process is used to remove deteriorated or low-quality grains from rice, thereby ensuring that the produced rice meets product standards and has a uniform appearance.
[0003] Current color sorters, after mechanically sorting rice, require separating spoiled rice from the sorted rice for further feeding. However, when the rice flow rate is too high, it easily accumulates on the pipe wall, causing blockages. To solve this problem, existing methods mostly use tapping and vibration to clear blockages, which results in high noise, high energy consumption, and damage to rice grains. How to invent a new type of color sorter for rice processing to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a new type of color sorter for rice processing, which aims to improve the problem that when the rice flow rate is too large during feeding, it is easy to accumulate on the pipe wall and form blockages. Currently, in order to solve this problem, most existing methods for clearing blockages during feeding use the method of knocking and vibration, which has the problems of high noise, high energy consumption and damage to rice grains.

[0008] Preferably, the cam is located between the two sets of feed tubes, and the protrusion of the cam cooperates with the side wall of the extrusion plate.
[0009] Preferably, the four sets of the dial plates are arranged in a linear array on the outer wall of the movable rod, the dial plates are located inside the feed tube, and the dial plates are arranged at an angle.
[0010] Preferably, the side wall of the feed tube has two sets of through holes, and the movable rod is slidably connected within the through holes.
[0011] The beneficial effects of this utility model are:
[0012] 1. This utility model, by setting up a clearing mechanism, uses a cam to indirectly strike the extrusion plate, and with the cooperation of a spring, drives the paddle plate to move radially and directly act on the blockage point, resulting in high clearing efficiency and a lower rice breakage rate than traditional knocking and vibrating methods, thus improving color sorting effect.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example, refer to Figures 1-3 A novel color sorter for rice processing includes a mounting frame 1 and a color sorter 2 mounted on the mounting frame 1. The top of the mounting frame 1 is provided with two sets of feeding pipes 3 connected to the color sorter 2. One set of feeding pipes 3 discharges qualified rice, and the other set of feeding pipes 3 discharges unqualified rice. The device also includes a clearing mechanism 4: the clearing mechanism 4 is mounted on the mounting frame 1 and can clear the feeding pipes 3 to prevent excessive and rapid rice discharge from clogging the inner wall of the feeding pipes 3.
[0021] The unblocking mechanism 4 includes a support rod 400 on the mounting frame 1. A sleeve 406 is provided at one end of the support rod 400. A rotating shaft 410 is connected to the inner wall of the sleeve 406 via a bearing. A cam 405 is provided at one end of the rotating shaft 410. A driven bevel gear 409 is sleeved on the outer wall of the rotating shaft 410. A driving bevel gear 408 meshes with the driven bevel gear 409 inside the sleeve 406. A motor 407 is provided on the side wall of the sleeve 406. The output end of the motor 407 is connected to the side wall of the driving bevel gear 408. Movable rods 403 are movably inserted through the side walls of both sets of discharge pipes 3. Two sets of... The movable rod 403 is slidably connected within the through hole. Under the action of the through hole, the reciprocating movement of the movable rod 403 is more stable, thereby driving the movement of the lever plate 404 to be more stable. Both ends of the movable rod 403 are provided with extrusion plates 401. The cam 405 is located between the two sets of feed tubes 3, and the protrusion of the cam 405 matches the side wall of the extrusion plate 401. Four sets of lever plates 404 are sleeved on the outer wall of the movable rod 403. Two sets of springs 402 are sleeved on the outer wall of the movable rod 403. One end of the spring 402 is connected to the side wall of the extrusion plate 401, and the other end of the spring 402 is connected to the outer wall of the feed tube 3.
[0022] It should be noted that when the cam 405 rotates, the protrusion contacts and squeezes the extrusion plate 401, thereby pushing the movable rod 403 to move towards the center of the lower feed tube 3. The paddle plate 404 expands radially inside the feed tube 3, stirring up the accumulated rice grains and preventing blockage.
[0023] Four sets of levers 404 are arranged in a linear array on the outer wall of the movable rod 403. The levers 404 are located inside the feed tube 3 and are set at an angle.
[0024] It should be noted that the lever 4040 is made of silicone material, and the lever 400 is tilted at 35 degrees, which allows for better movement of the rice.
[0025] Working principle: Rice enters the color sorter 2 for screening. After screening, one set of feed pipes 3 discharges qualified rice, and the other set of feed pipes 3 discharges unqualified rice. At this time, the motor 407 starts and drives the active bevel gear 408 to rotate. The active bevel gear 408 meshes with the driven bevel gear 409 to rotate. The driven bevel gear 409 drives the rotating shaft 410 and cam 405 to rotate. When the cam 405 rotates, the protrusion contacts the extrusion plate 401 and squeezes it. The extrusion plate 401 squeezes the spring 402, thereby pushing the movable rod 403 to move to the center of the lower feed pipe 3. The paddle plate 404 expands radially in the feed pipe 3, stirring up the accumulated rice grains to avoid blockage. When the cam protrusion separates from the extrusion plate 401, the extrusion plate 401 resets under the action of the spring 402, and the paddle plate 404 retracts.
[0026] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
