Technical Field

[0001] The utility model relates to the technical field of agricultural product quality detection, in particular to a quick screening device for agricultural product quality detection. Background Art

[0002] Agricultural products refer to primary products derived from agriculture, forestry, animal husbandry, and fisheries. These include plants, animals, microorganisms, and their products obtained through agricultural activities, such as rice, sorghum, peanuts, corn, wheat, and local specialties. After years of development, wheat has become one of the world's most widely distributed, largest crops, second in total production, most traded, and most nutritious. Wheat is a nutritious and economically valuable commodity grain. Wheat caryopsis is a staple food for humans. When ground into flour, it can be made into bread, steamed buns, biscuits, noodles, and other foods. Fermented wheat can be made into beer, alcohol, and liquor (such as vodka). Besides human consumption, small amounts of wheat flour are used to produce starch, ethanol, and gluten. Wheat starch has anti-inflammatory, analgesic, and dehumidifying properties and can also be used as a base for pharmaceuticals. Wheat gluten is used to make monosodium glutamate. When testing wheat quality, it is important to remove impurities and select clean, plump wheat. This allows for accurate determination of the content of nutrients such as protein, carbohydrates, and dietary fiber, providing a basis for food processing and nutritional assessment.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 4 , the utility model provides a technical solution:

[0025] A quick screening device for agricultural product quality inspection includes an air separation component, which includes an air separation box 1. A feed hopper 2 is fixedly installed on the top of the air separation box 1. A buffer plate 10 is obliquely arranged above the interior of the air separation box 1, and the buffer plate 10 is fixedly connected to the inner wall of the air separation box 1. A fan 3 is fixedly installed on one side of the air separation box 1, and the output end of the fan 3 faces the interior of the air separation box 1. A dust outlet 4 is fixedly installed on the other side of the air separation box 1, and a dust exhaust pipe 11 is fixedly installed on one side of the dust outlet 4. A dust storage bag 12 is wrapped and fixed on the bottom of the dust exhaust pipe 11.

[0026] By setting up the fan 3, the low-density impurities in the wheat entering the air separation box 1 can be blown out, and the impurities can be concentrated in the dust storage bag 12 through the dust outlet 4 and the dust exhaust pipe 11, thereby improving the screening effect. At the same time, it is convenient for the operator to centrally clean the impurities and avoid polluting the environment. When used in conjunction with the buffer plate 10, the wheat added to the feed hopper 2 can be buffered, reducing its speed through the air separation box 1, thereby improving the air separation effect.

[0027] It also includes a stone removal component, which includes a box body 5. The top of one side of the box body 5 is fixedly connected to the bottom of the air separation box 1. A partition plate 6 is fixedly installed inside the box body 5. An overflow trough 7 is provided on the partition plate 6. A sedimentation chamber 8 is provided on one side of the partition plate 6. An inspection plate 17 is provided above the sedimentation chamber 8. The inspection plate 17 is fixed to the side wall of the box body 5 by screws. An observation window 18 is provided on one side of the sedimentation chamber 8. The observation window 18 is opened on the side wall of the box body 5, and a transparent plate is sealed in the observation window 18.

[0028] By setting up a sedimentation box, impurities such as stones and soil blocks with higher density in the wheat can be settled to the bottom of the sedimentation chamber 8, further improving the screening effect. At the same time, the wheat is cleaned. By setting up an inspection plate 17, it is convenient for the operator to clean the inside of the sedimentation chamber 8. When used in conjunction with the observation window 18, it is convenient for the operator to observe the internal situation of the sedimentation chamber 8.

[0029] A filter chamber 9 is provided on the other side of the partition plate 6. A card slot 13 is fixedly installed on one side of the filter chamber 9 in the overflow trough 7. A support frame 14 is clamped in the card slot 13. A filter bag 15 is fixedly installed on one side of the support frame 14. A water pump 16 is fixedly installed on one side of the box body 5. The water inlet end of the water pump 16 is fixedly connected to the bottom of the filter chamber 9. The water outlet end of the water pump 16 is fixedly connected to one side of the box body 5 through a connecting pipe 19, and is connected to the top of the sedimentation chamber 8.

[0030] By setting up the partition plate 6 and the overflow trough 7, the upper water and the wheat can enter the filter chamber 9 together, thereby being separated from the impurities and improving the screening effect. When used in conjunction with the filter bag 15, the wheat can be collected in the filter bag 15, which is convenient for the operator to take out and the water can be drained out at the same time. In conjunction with the water pump 16 and the connecting pipe 19, the water can be reused, reducing water resource consumption.

[0031] When in use, move the device to the designated position, slowly add clean water into the filter chamber 9, then turn on the water pump 16, the water pump 16 extracts the clean water in the filter chamber 9, and pumps it into the sedimentation chamber 8 through the connecting pipe 19, keeping the clean water level in the filter chamber 9 lower than the bottom of the filter bag 15. When clean water overflows from the overflow tank 7, stop adding clean water, keep the water pump 16 working, turn on the fan 3, and blow a high-speed airflow into the air separation box 1. Slowly add the wheat sample to be tested into the feed hopper 2. After passing through the feed hopper 2, the wheat sample slides down on the buffer plate 10 and enters the air separation box 1. The high-speed airflow blows out the impurities with smaller density, and the wheat sample and the impurities with larger density are blown out. The wheat sample is collected in the filter bag 15 and the clean water flows out from the gap of the filter bag 15 and enters the bottom of the filter chamber 9, and is pumped into the sedimentation chamber 8 by the water pump 16 for reuse. The situation in the sedimentation chamber 8 is observed through the observation window 18. When all the wheat samples in the sedimentation chamber 8 enter the filter bag 15, wait for all the water in the wheat samples in the filter bag 15 to be drained out, take out the support frame 14 and the filter bag 15 together, dry the wheat samples and then carry out quality inspection.
