Automatic sample preparation equipment

Abstract

The invention discloses automatic sample preparation equipment. The automatic sample preparation equipment comprises a box body, a conveying device, a vibration mixing device, three-petal molds, flowsensors, switch valves and a controller, wherein the vibration mixing device is arranged below an output end of the conveying device; multiple discharge ports are arranged on the vibration mixing device, and the three-segment molds are arranged below the discharge ports; the number of the three-petal molds is equal to that of the discharge ports of the vibration mixing device; the flow sensors andthe switch valves are arranged on the discharge ports; after the controller controls the conveying device and the vibration mixing device to stop working, the switch valves of the controller are opened, the flow sensors detect the flow of the solid materials which are required by the mixed vibration test and flow out from the discharge ports, and transmit flow data to the controller; and when theflow reaches a set value, the controller controls the switch valve to be closed. The automatic sample preparation equipment disclosed by the invention has the advantages of being multifunctional, automatic in sample preparation and high in working efficiency.

Description

technical field [0001] The invention relates to a sample preparation device, in particular to an automatic integrated sample preparation device. Background technique [0002] Specimens in soil triaxial testing are usually prepared and saturated using a three-lobed mold. Test personnel need to perform standard operations such as sample preparation, stirring, and saturation before the test. When the number of samples is large, due to the cumbersome sample preparation process, multiple sample preparations at the same time will greatly reduce the progress of the test. In addition, in the process of using a shaking table for saturation, there may be problems such as sample spillage or the collapse of the three-lobe mold if multiple samples are carried out at the same time; if a single sample is shaken each time, there will be a problem of low efficiency. [0003] Therefore, designing an integrated automatic sample preparation geotechnical test equipment with the functions of mi...
