CCD detector for rice color selector

Abstract

The invention discloses a CCD detector for a rice color selector. The CCD detector for the rice color selector comprises a CCD detector body, wherein a glass cover plate is fixedly connected to the bottom of the CCD detector body; CCD lenses are fixedly connected to the top of the inner wall of the CCD detector body; a dust removal guide rod is fixedly connected to the bottom of the CCD detector body; a dust removal slide block is movably connected to the surface of the dust removal guide rod; a laser lamp is fixedly connected to the top of the inner wall of the CCD detector body and located at the right side of the CCD lenses; a control circuit board is fixedly connected to the top of the dust removal guide rod; a light ray sensor is fixedly connected to the top of the control circuit board and at a position corresponding to the laser lamp; and a micro drive motor is fixedly connected to the bottom of the dust removal guide rod and located at the right side of the dust removal slide block. The CCD detector for the rice color selector solves the problem that a CCD detector cannot normally run because dust on the glass of a lens cannot be timely and effectively cleaned, of a traditional rice color selector, through the cooperation of the laser lamp, the control circuit board, the light ray sensor and the micro drive motor.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a CCD detector of a rice color sorter. Background technique [0002] Rice is the main food in people's life. During the process of harvesting, milling, drying, etc., there will be some impurities such as twigs, small stones, and some rice grains that have their own problems. Picking out sundries is time-consuming and labor-intensive and inefficient, so people invented a rice color sorter. The rice reaches the vibrating feeding mechanism from the feeding device, then slides down through the slideway, and passes through the CCD detector. When there are sundries or bad rice When passing through, the lower air gun is automatically turned on to remove it. Due to the dust in the rice, after the existing rice color sorter is used for a period of time, the dust in the rice will adhere to the glass in front of the CCD lens. The sensitivity of the CCD lens decreases, thereby affec...
