Material chemical preparation sampling analysis device

The invention provides a material chemical preparation sampling analysis device which comprises a shaking assembly, and the shaking assembly comprises an electric telescopic rod, a fixing plate, a connecting plate, a fixing column, a U-shaped clamping block, a connecting column, a rotating disc, two fixing blocks, a connecting frame, two sliding columns, a rotating shaft and a time controller. One end of the electric telescopic rod is hinged to the upper surface of the fixing plate. A fixing plate is pushed downwards through an electric telescopic rod, a connecting plate pushes a fixing column to be inserted into a U-shaped clamping block, the connecting column drives a connecting frame to reciprocate front and back, then the U-shaped clamping block drives the fixing column to move, a test tube is driven to shake, a chemical material in the test tube is evenly heated, and when the preset heating time is reached, the test tube is heated. The time controller controls the electric telescopic rod to contract, so
