The invention discloses a liquid sampling device for quality safety detection of agricultural products. The liquid sampling device comprises a box body, a filter screen is fixedly connected in the box body, the upper end of the box body is provided with a feed inlet, the upper end of the box body is provided with three shaft rods in a penetrating manner, the bottoms of the three shaft rods are all located above the filter screen, the shaft rods are fixedly connected with stirring blades, a transmission mechanism is arranged among the three shaft rods, a pressurizing mechanism is installed on the box body, a funnel is fixedly connected in the box body, the lower end of the funnel is fixedly connected with a conveying pipe, and a short rod rotationally connected with the box body is arranged on the side wall of the bottom of the box body in a penetrating mode. Vegetables can be effectively and efficiently crushed, vegetable liquid can be obtained, meanwhile, the interior of the box body can be pressurized, the flowing speed of the vegetable liquid can be increased, the collection efficiency can be improved, obtained crude vegetable liquid can be centrifuged, vegetable liquid without residues can be obtained, and liquid sampling of agricultural products is achieved.
Description
technical field [0001] The invention relates to the technical field of agricultural products, in particular to a liquid sampling device for detecting the quality and safety of agricultural products. Background technique [0002] There are many inspection contents of agricultural products, such as moisture, quality and other indicators. Before carrying out the detection work, it is necessary to collect samples; the existing liquid sampling device for the quality and safety detection of agricultural products requires staff to manually chop or mash the agricultural products (vegetables, melons and fruits, etc.). In order to improve the accuracy of the inspection, work Personnel often need to prepare a large amount of the above-mentioned original solution to be tested, which is time-consuming and laborious. At the same time, some agricultural products are difficult to chop or grind by hand, which often increases the difficulty of collecting test samples. [0003] The prior art ...
