Drilling fluid sampling device for geological drilling engineering

The drilling fluid sampling device comprises a supporting plate, the top of the supporting plate is fixedly connected with a water tank through a bolt, the top of the water tank is fixedly communicated with a water inlet pipe, the bottom of the left side of the water tank is fixedly connected with a water pump through a bolt, and the water inlet end of the water pump penetrates into an inner cavity of the water tank. The water outlet end of the water pump fixedly communicates with a hose, and vertical plates are welded to the left side and the right side of the top of the supporting plate correspondingly. According to the drilling fluid sampling device, the third motor, the winding drum and the steel wire rope are matched, so that the drilling fluid sampling device has the advantage of being capable of automatically sampling drilling fluid, the sampling barrel is automatically lifted, the drilling fluid is conveniently sampled, and the sampling efficiency is improved; and through cooperation of a water sprayi
