Description

Technical Field

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

[0002] Microorganisms cover many types, both beneficial and harmful, and are widely involved in many fields such as food, medicine, industry and agriculture, environmental protection, and sports. Some microorganisms can be seen with the naked eye, such as mushrooms, Ganoderma lucidum, shiitake mushrooms, etc., which belong to the fungi. Most agricultural products need to be tested for agricultural product microorganisms during production. Announcement No. CN217542571U describes a sample preparation device for testing agricultural product microorganisms. The device opens the collection basin cover installed above the collection basin and the centrifugal filter cartridge cover installed above the centrifugal filter cartridge, inserts the rotating shaft into the centrifugal filter cartridge, and inserts the bottom of the rotating shaft into the rotating bearing connection groove. The agricultural products to be tested are then placed into the centrifugal filter cartridge, the centrifugal filter cartridge cover is dry-closed on the centrifugal filter cartridge, and the collection basin cover is closed on the collection basin, so that the hexagonal card block fixed above the rotating shaft is engaged in the hexagonal card slot opened below the motor box. The telescopic cylinder is controlled by the micro-operation panel to lower the motor box. At this time, the cylindrical part of the upper half of the rotating shaft is located inside the hexagonal limit hole. The motor box is opened, so that the rotating shaft drives the cutting knife to crush and cut the agricultural products in the centrifugal filter cartridge. After the cutting is completed, the machine is turned off and the rotating shaft is waited for to stop operating.

[0003] When the above device is in use, the solid-liquid separation effect of agricultural products is increased and secondary filtration is achieved through the design of the filter holder and the filter. The filter can also be replaced at the same time. The design of the centrifugal filter barrel is different from the extrusion method of the traditional agricultural product microbial sampling machine. However, when the above device is in use, when the centrifugal filter barrel cover is rotating, the limit hole cannot be effectively connected with the limit column. When it is connected, the sampling equipment needs to be shut down, which may easily reduce the efficiency of agricultural product sampling. Utility Model Content
