Description

Technical Field

[0001] The utility model relates to a testing machine, in particular to a grain screening testing machine. Background Art

[0002] Grain inspection machines can usually perform multiple tasks, such as measuring the moisture content, grain size, color, shape of grains, detecting impurities (such as foreign matter, mold, pests, etc.), or determining the nutritional content and content of grains through chemical analysis:

[0003] However, if grains pile up during sieving, part of the grains may be blocked or densely piled up, making it impossible for sensors or detection equipment to fully contact or accurately detect all particles, thereby affecting the accuracy and comprehensiveness of the detection. Therefore, a grain sieving and inspection machine is urgently needed.

[0004] It should be noted that the above content belongs to the technical cognition scope of the utility model applicant and does not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a grain screening and testing machine.

[0006] To achieve the above-mentioned purpose, the utility model proposes a grain screening and testing machine, comprising a screening storage frame;

[0007] One side of the screening storage frame is fixedly connected to the bottom end of the U-shaped frame through a connecting frame, two sliding rods are inserted and connected to both sides of the inner wall of the U-shaped frame, one end of the four sliding rods are respectively fixedly connected to the two ends of the inner frame, support frames are fixedly provided on both sides of the top of the inner frame, and connecting rods are fixedly provided at the bottom ends of the two support frames. The bottom ends of the two connecting rods are fixedly connected to the two sides of the bottom end of the inner wall of the inner frame, and the two connecting rods are inserted and connected to the two sides of the middle box, and a double-headed drive motor is fixedly provided in the middle position inside the middle box, and counterweights are fixedly provided at both output ends of the double-headed drive motor.

[0027] Specifically, a connecting plate 7 is fixedly provided on one side of the two supporting frames 15 , and the connecting plate 7 is fixedly connected to the side wall of the screening frame 6 .

[0028] Specifically, a fixing seat 2 is fixedly provided at the middle position of both sides of the screening storage frame 1, a supporting platform 4 is fixedly provided at the top of the two fixing seats 2, and an LED light source lamp 5 is fixedly provided between the two supporting platforms 4.

The two output ends of the double-headed drive motor 17 drive the two staggered counterweights 16 to rotate. During the rotation of the counterweights 16, the U-shaped frame 9 will be driven to swing back and forth along the slide rod 14, thereby driving the grain inside the screening frame 6 to vibrate back and forth. During the vibration, the incomplete grain particles in the grain will be screened into the inside of the screening storage frame 1, and then the LED light source switch is turned on. The LED light source 5 irradiates light on the flat grain, and then the photoelectric sensor 8 is used to capture or record the position of the interaction between light and particles, so as to accurately measure the required characteristics. This method can effectively vibrate and screen the grain inside the screening frame 6, help redisperse the grain, and make it more evenly distributed in the detection area, which helps to ensure that the grain particles can be fully detected and evaluated.
