The suction machine is composed of a motor, a rack, a hose, a shaftless spiral blade and a suction head. Its working principle is that the motor is fixed on the rack, the shaftless spiral blade is installed in the hose, and the front end is connected with the suction head. When the motor is started, the motor drives the shaftless spiral blade to rotate, and the grain at the suction head will rise along the helical rise angle of the shaftless spiral blade under the action of the shaftless spiral blade, and when it reaches the discharge port, it will be automatically unloaded due to gravity.
