Beschreibung
Zusammenfassung:	The invention provides a grain sampling device capable of sampling automatically and uniformly. The grain sampling device comprises a driving mechanism, a sampling mechanism and a controller, wherein the driving mechanism comprises a first motor and a second motor; the first motor and the second motor are electrically connected with the controller; the sampling mechanism comprises a sampling pipe and a spiral blade; the spiral blade is arranged in the sampling pipe; the first motor and the spiral blade are coaxially connected and the first motor drives the spiral blade to rotate; an output end of the second motor and the sampling pipe are provided with gears; the gears are connected with each other through a chain; and the second motor drives the sampling pipe to rotate through the chain and the gears. The grain sampling device has the beneficial effects that the controller is connected with the first motor and the second motor, so that the starting and stopping, and rotary speeds of the sampling pipe and the
