Abstract
A unidirectional or bidirectional sand dispensing device, including a discharge port (), the discharge port includes a lower plate () and an upper plate (), the upper plate is provided above the lower plate, an included angle between a horizontal plane and a straight line where an endpoint of a free end of the upper plate and an endpoint of a free end of the lower plate are located is a leakage angle (), that is to say, a particulate material forms an inclined plane between the upper plate and the lower plate, and an included angle between the inclined plane and the horizontal plane is the leakage angle, which can be adjusted by changing relative positions of the upper plate and the lower plate. The direction of an opening of the sand passing passage is opposite to a moving direction during the sand dispensing operation. When the sand dispensing operation is stopped, the leakage angle is less than or equal to the static repose angle of the particulate material, and is greater than or equal to zero, which ensures that the particulate material will not slide down, and the phenomenon of sand leakage is eliminated. When the sand dispensing operation is being carried out, the leakage angle is greater than or equal to the dynamic repose angle of the particulate material, which ensures that the particulate material will slide down along the inclined plane and that the sand is dispensed relatively uniformly.
