Description

Technical Field

[0001] The utility model relates to the technical field of wheat detection, in particular to a wheat imperfect grain detection system. Background Art

[0002] Imperfect kernels are grains that have been damaged but still have edible value. These include insect-damaged kernels, diseased kernels, broken kernels, immature kernels, sprouted kernels, and moldy kernels. Imperfect kernels are easily produced during grain production, storage, packaging, and transportation, seriously affecting grain quality and safety. Testing for imperfect kernels can not only rationally check overall grain quality, but also facilitate improvements in various aspects of the grain industry.

[0003] At present, most imperfect detectors basically use plane scanning to collect images, arranging hundreds or thousands of samples at a time and scanning them into images. This makes it impossible to collect 360 degrees of each sample, resulting in detection loopholes.

[0004] Therefore, we proposed a wheat imperfect grain detection system to solve the above problems. Utility Model Content

The mounting frame 2 is provided on the base 1; the vibrating loading tray 3, the vibrating loading tray 3 is provided on the base 1, and is used to transport the wheat grains in the tray to the discharge port in an orderly manner.

[0029] The transfer mechanism 4 includes a belt conveyor 41 and a material limiting bend 42. The belt conveyor 41 is fixed on the mounting frame 2, and its feed end is connected to the discharge port of the vibrating loading tray 3. The discharge end of the belt conveyor 41 is provided with a material limiting bend 42. The transfer mechanism 4 plays a transfer role on the wheat grains transported by the vibrating loading tray 3, and sends them to the sorting mechanism 6 in an orderly manner.

[0030] The high-speed camera 5 is located below the discharge port of the limiting bend 42. There are multiple high-speed cameras 5 and they are arranged in a circle. Multiple high-speed cameras 5 form a wheat discharge channel. There are preferably four high-speed cameras 5. The four high-speed cameras 5 can perform 360° photo detection on the wheat grains in the discharge channel, reduce the blind spots of detection, make the detection range more comprehensive, and improve the detection effect. The setting of the limiting bend 42 guides the wheat grains so that they can accurately fall into the wheat discharge channel.

[0031] like Figure 2 、 3 As shown in FIG4 , the sorting mechanism 6 includes a material distribution box 61 in the shape of an inverted pyramid, specifically a seven-sided pyramid structure, corresponding to moldy grains, sprouted grains, insect-eaten grains, damaged grains, diseased grains (eruptoresin grains, black embryo grains), heat-damaged grains and normal grains. The bottom of multiple side walls of the material distribution box 61 are provided with a material distribution outlet, and an opening and closing component 62 for opening and closing the material distribution outlet is provided inside the material distribution outlet.
