Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product detection, and more specifically, to a sampling device for agricultural product detection. Background Art

[0002] Agricultural products are items produced in agriculture, such as rice, sorghum, peanuts, corn, wheat, and local specialties of various regions. The state stipulates that primary agricultural products refer to plants, animals and their products obtained from agricultural activities, excluding various processed products. Agricultural products need to be tested before entering the market. The testing requires the use of sampling devices to sample agricultural products. The sampling device crushes the agricultural products into powder for testing. However, the existing sampling devices for agricultural product testing have the following deficiencies when crushing agricultural products: the agricultural products are placed inside the sampling device and crushed and sampled by crushing tools, but there are gaps between the crushing tools, and the agricultural products are prone to sinking during crushing, which makes it difficult to fully crush the agricultural products, resulting in larger particles of the crushed agricultural products, making it difficult to accurately test them. At the same time, some tests require the agricultural products to be formed into a viscous liquid for testing, while the sampling device can only crush the agricultural products into powder, and it is also necessary to use external equipment to add water and stir to mix it, which reduces the convenience of sampling. Summary of the invention

Apply elastic force to the connection ends of the two opening and closing plates through the spring slide, so that the opening and closing plates can be sealed and connected to the lower end of the drawer. When only powder samples are needed, the drawer can be pulled out to collect the powder. When the powder samples need to be made into a viscous liquid, the cylinder is started to rise upward. At this time, the connection ends of the two opening and closing plates are pushed up through the output end of the cylinder. At this time, the lower end of the drawer is in an open state, which is convenient for the collected powder to continue to be discharged downward into the mixing mechanism for processing, so that powder and viscous liquid sampling of agricultural products can be performed; 3. The motor box is started to drive the rotating rod to rotate inside the mixing box. During the rotation, two sets of symmetrically installed spiral blades can fully stir the water source and powder inside the adding box in both directions, and the stirring rod can also stir the powder far away from the spiral blades to ensure that the powder and water source are fully stirred and mixed, and a viscous liquid is obtained by sampling, thereby improving the convenience of agricultural product sampling.

The three supporting plates 4b can support the front, middle and rear positions of the two groups of crushing knives c56 to prevent the agricultural products from falling down directly due to insufficient crushing. There are multiple partition plates 4v, which are evenly distributed laterally between the two support plates 4b to fill the lower ends of the gaps between the laterally distributed crushing cutters c56 in the same group, so as to prevent the crushed agricultural products from falling down from the gaps between the crushing cutters c56 when the crushed particles are still large, thereby effectively improving the fineness of the crushing of the agricultural products and thus improving the accuracy of the detection.

[0022] The collection box c8 includes a fixed box c86, a drawer c85, a soft magnetic strip c89, a magnetic plate c81, a spring slide c87, an opening and closing plate c84, a cylinder c88, and a guide groove c83. The fixed box c86 is fixedly installed at the lower end of the chassis c2, and the fixed box c86 is located below the lower guide groove 4k. The drawer c85 is slidably installed inside the fixed box c86. The front end of the drawer c85 is provided with a soft magnetic strip c89, and the soft magnetic strip c89 conflicts with the magnetic plate c81. , the magnetic plate c81 is fixedly installed inside the edge of the fixed box c86, the spring slide c87 is embedded in the inner wall of the drawer c85, and the upper end of the opening and closing plate c84 is slidably installed inside the spring slide c87, the lower end of the opening and closing plate c84 is in conflict with the lower end of the drawer c85, the cylinder c88 is fixedly installed in the middle of the lower end of the fixed box c86, the output end of the cylinder c88 is located directly below the upper end of the opening and closing plate c84, and the guide groove c83 is embedded in the lower end of the fixed box c86; The spring slides c87 are provided with two and are installed in the drawer c85 in a front-to-back symmetrical manner. At the same time, the opening and closing plates c84 are provided with two and are installed in a left-right symmetrical manner to form an inverted "V"-shaped structure. The spring slides c87 apply elastic force to the connecting ends of the two opening and closing plates c84, so that the opening and closing plates c84 can be sealed and connected to the lower end of the drawer c85, so as to facilitate the collection of the crushed agricultural product powder. The guide groove c83 is a cavity structure with a wide upper end and a narrow lower end, and there are two of them, which are symmetrically installed on the outside of the cylinder c88. When the powder needs to be adjusted into a viscous liquid, it rises by starting the cylinder c88. At this time, the connecting ends of the two opening and closing plates c84 are pushed up by the output end of the cylinder c88. At this time, the outer lower ends of the opening and closing plates c84 are retracted inwards, and the lower end of the drawer c85 is open, so that the collected powder can continue to be discharged downward into the mixing mechanism c1 for processing. The specific usage and function of this embodiment are as follows: In the present invention, when agricultural products are tested and sampled, the agricultural products are put into the chassis c2 from the feed port J. At this time, the starting motor c59 is driven by the transmission component c57, so that the two rotating rods c52 are synchronously operated to drive the crushing tool c56 to crush and sample the agricultural products. During the crushing process, a sliding block c53 and a spring rod c51 are provided at the four connection ends of the crushing tool c56 and the rotating rod c52, so that the rotating rod c52 can drive the crushing tool c56 to rotate and can perform lateral elastic adjustment at the same time, effectively improving the effect of fine crushing of agricultural products.

The gap between them falls downward, which effectively improves the fineness of the crushing of the agricultural products, thereby improving the accuracy of the detection. The crushed and sampled agricultural products are discharged downward into the drawer c85 for collection, and are fixed by the magnetic attraction of the soft magnetic strip c89 and the magnetic attraction plate c81 to improve the stability of the collection of the drawer c85. During collection, the spring slide c87 applies elastic force to the connecting ends of the two opening and closing plates c84, so that the opening and closing plates c84 can be sealed and connected to the lower end of the drawer c85. When only powder samples are needed, the drawer c85 can be pulled out to collect the powder. When the powder samples need to be made into a viscous liquid, the cylinder c88 is started to rise upward. At this time, the connecting ends of the two opening and closing plates c84 are pushed up through the output end of the cylinder c88. At this time, the outer lower end of the opening and closing plate c84 is retracted inward, and the lower end of the drawer c85 is in an open state, which is convenient for the collected powder to continue to be discharged downward into the mixing mechanism c1 for processing, so that the agricultural products can be sampled as powder and viscous liquids.
