Rice mildew nondestructive detection device

Abstract

The invention discloses a rice mildew nondestructive detection device, and relates to the technical field of grain detection equipment, the rice mildew nondestructive detection device comprises a case and an image acquisition port arranged at the top of the case, a material adding and homogenizing mechanism and an overturningmechanism are sequentially arranged on the case, and the overturning mechanism comprises a support base fixed below an outlet of a material homogenizing slide way; conveying chains are rotationally arranged on the two sides of the supporting base, a plurality of rotating shafts are rotationally connected between the two conveying chains, a plurality of arc-shaped ring grooves are evenly formed in each rotating shaft at intervals, the gap between the corresponding arc-shaped ring grooves in every two adjacent rotating shafts is smaller than the size of rice, and a plurality of overturning grooves used for containing the rice are formed in the arc-shaped ring grooves; a driving mechanism for driving the rotating shafts and the discharging rollers to rotate synchronously is arranged in the case, and a collecting box is placed on one side of the supporting base. The rice mildew nondestructive detection device provided by the invention is convenient and reliable to use, and stable overturning of rice is ensured through the arc-shaped ring grooves and the overturning grooves, so that the detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of grain detection equipment, in particular to a nondestructive detection device for rice mildew. Background technique [0002] As important grains, rice and wheat are widely planted all over the world. At present, the output of rice and wheat in my country ranks first in the world, but grain mildew has always been a major problem that plagues human food security. During the rice storage and production process of rice production and processing enterprises, mildew detection of rice is required. [0003] The existing Chinese invention patent with authorized notification number CN110118772B discloses a portable double-sided non-destructive detection device for rice and wheat mildew, including a turning device, a box body and a receiving tray, and a two-dimensional code is pasted on the outside of the box body; There is an opening area on the top of the box, which is used for the image acquisition equipment to ...

Problems solved by technology

[0004] With the above-mentioned technical scheme, when in use, the staff places the rice evenly between the rollers, and then the power device drives the rollers to rotate, and drives the rice to rotate and turn over through friction; it cooperates with the image acquisition equipment for detection; but in actual use During the process, what the rice processing enterprises need to detect often needs to detect the rice with skin in the warehouse. However, due to the shape and surface smoothness of the rice with skin, the direct use of the drum rotation will often cause the rice to idle, and it is further impossible to realize the turning. surface, resulting in a large error in the detection results; at the same time, the detection efficiency of the manual flattening method is low, and the rice is easy to stack and block each other during the rotation of the drum.
