Technical Field

[0001] The utility model relates to the technical field of grain detection, in particular to a corn kernel mildew detection device. Background Art

[0002] Corn kernels, also known as millet kernels. Fresh corn kernels have a firm texture, like raisins, and a sweet taste. Corn kernels are a grain suitable for all ages, and their main edible effect is to delay aging. Corn kernels need to be quality tested before leaving the factory to detect whether the corn kernels are moldy or deteriorated, so as to ensure food safety. Therefore, a corn kernel mold detection device is usually required.

[0003] For example, an existing Chinese patent (publication number: CN215525739U) discloses a rice mildew detection device, which uses a belt conveyor to convey bagged rice, and uses a loading plate to receive the bagged rice from the belt conveyor, and then drives the loading plate up through a lifting mechanism to move the bagged rice into the sample chamber, so as to perform mildew detection; the linear lifting method is more stable than the existing swinging method, the device has higher stability and longer service life.

[0004] However, the rice mildew detection device designed above still has some disadvantages in practical application: although the rice mildew detection device designed above can achieve the purpose of detecting rice grains, the rice mildew detection device puts the rice grains into a rice bag for overall detection during detection, which makes it impossible for the detection device to effectively detect the rice grains deeper in the rice bag, thereby reducing the detection accuracy.

[0005] Therefore, we designed a corn kernel mildew detection device to solve the above problems. Utility Model Content

[0032] The electromagnetic valve 5 is usually a gate valve controlled by an electromagnetic, the flow direction of the gate valve is perpendicular to the fluid direction, and the electromagnetic gate valve can only be fully opened and fully closed. The principle is: when power is turned on, the electromagnetic valve coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when power is turned off, the electromagnetic force disappears, and the elastic force presses the closing member onto the valve seat, and the valve closes.

Since detector 3 is an existing disclosed technology, it will not be explained in detail in this specification.

[0035] Working principle:

[0036] When in use, first connect all the electrical appliances involved in the installation base 1 to an external power supply. When it is necessary to inspect the quality of the corn kernels, open the electromagnetic valve 5 to allow the corn kernels stored in the storage box 4 to fall onto the belt 9 through the electromagnetic valve 5. Then turn on the motor 10 and the detector 3 to move the belt 9 and transport the corn kernels thereon. When the corn kernels reach the detector 3, they can be scanned and detected by the detector 3. If the corn kernels are qualified, they continue to be transported so that the corn kernels move to the end of the belt 9 and fall into the receiving box 7 for centralized collection. If moldy corn kernels are detected, the detector 3 controls the motor 10 to be turned off and the rice position input The corn kernels are sent to the display screen 23 for personnel to check and pick out moldy corn kernels, thereby achieving the effect of quickly and accurately detecting the mildew of corn kernels. In addition, when the belt 9 transports the corn kernels, the motor 14 is turned on to make the rotating shaft 12 drive the turntable 13 to rotate, so that the transmission shaft 15 drives the rotating part 16 to drive the U-shaped frame 8 to shake on the mounting base 1. During this process, the ball 22 will roll in the slide groove 20, and the sliding friction of the U-shaped frame 8 can be changed to rolling friction, thereby reducing mechanical loss. The corn kernels piled on the belt 9 can be shaken and flattened, thereby facilitating the detection of the detector 3, and the detection accuracy can be further improved.
