Description

Technical Field

[0001] This utility model relates to the field of rice processing equipment technology, and in particular to a high-precision rice processing color sorter. Background Technology

[0002] In the rice processing industry, color sorters are key equipment for achieving refined rice sorting. They use optical recognition technology to separate discolored rice grains and impurities from qualified rice, and their performance directly affects the quality and market value of the finished rice product. Currently, most rice color sorters on the market adopt a structure that combines a vibrating feed trough with negative pressure dust collection. Vibration enables continuous conveying of rice, while negative pressure airflow carries away light impurities.

[0003] However, existing technologies still have significant drawbacks: First, the vibration amplitude and tilt angle of the feed trough used for rice guiding are mostly fixed parameters, making it difficult to dynamically adjust according to the characteristics of rice varieties and grain size. This can easily lead to uneven flow rates and accumulation blockages of different types of rice during the feeding process, thus affecting the recognition accuracy and processing efficiency of the color sorter. Second, the airflow control of the negative pressure dust collection system lacks flexibility. The single air intake and dust collection path cannot accurately adjust the airflow intensity. When processing rice with high impurity content, it is easy to cause incomplete separation of impurities or accidental suction of qualified rice. Third, the impurity filtration device mostly uses flat filter screens, which are easily clogged by dust and fine impurities after long-term use and lack convenient cleaning channels. This not only reduces the continuous working capacity of the equipment but may also lead to secondary pollution. In addition, during the movement of the feed trough in existing color sorters, the rigidly connected air pipes are prone to loosening or breaking due to mechanical vibration, affecting the operational stability of the equipment.

[0004] With consumers demanding higher quality rice and processing companies pursuing greater production efficiency, this utility model proposes a high-precision rice color sorter to solve the aforementioned problems.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0049] Working Principle: First, the power is turned on, and the rice to be color-sorted is introduced into the storage bin 2. The color sorter body 11 and servo motor 42 are then started. The servo motor 42 drives the first support rod 43 to rotate. Then, through the connection of the second support rod 44, the sleeve 45, and the third support rod 46, the guide trough 3 tilts and vibrates under the support and guidance of the guide assembly. At this time, the rice in the storage bin 2 slides towards the color sorter body 11 through the guide trough 3 and is divided into multiple streams under the action of multiple guide strips 4. As the guide trough 3 vibrates, the separating block 41, in conjunction with the guide strips 4, controls the flow rate of rice towards the color sorter body 11, thereby enabling... The rice falls at a suitable speed and quantity. At the same time, the exhaust fan 51 starts, and air is blown into the feed trough 3 from the air inlet pipe 52 through the dispersion pipe 53 to blow away the impurities in the rice. The impurities are collected by the suction pipe 54 through the dust collection hopper 541. After the impurities are sucked into the box 5, they are filtered and intercepted by the filter plate 501. The filtered impurities can be discharged through the discharge pipe, while the color-sorted rice flows out from the feed trough 12, completing the entire color sorting process. During this period, the inclination angle and vibration amplitude of the feed trough 3 can be changed by adjusting the limit bolt 451 according to the actual situation. The air intake of the air inlet pipe 52 can also be adjusted by adjusting the regulating valve to achieve the best color sorting effect.
