[0016] The present invention provides a coal transportation device with screening function. It has the following beneficial effects: (1) The invention sets a filter so that qualified coal will pass through the filter and fall onto the top of the conveyor belt, while larger coal will remain on the top of the filter. The coal can be initially screened and the larger coal will be removed to prevent it from falling directly onto the top of the conveyor belt and damaging the conveyor belt, thereby causing losses. The rotation of the shaft will drive the spring to accumulate force, and after the spring releases the accumulated force, it will drive the impact rod to hit the filter so that the coal in the filter will be vibrated and fall onto the top of the conveyor belt, thereby preventing the coal in the filter from accumulating too much and causing loss of the screening effect, thereby further improving work efficiency.

[0017] (2) The invention drives the reciprocating screw to rotate by rotating the shaft. The rotation of the reciprocating screw causes the electric L-shaped plate and the turning block to move back and forth.

The rotation of the reciprocating screw drives the scraper to rotate. The rotation of the scraper spreads the coal on the top of the conveyor belt more evenly, further improving the stability of the equipment.

[0018] (3) In this invention, the valve draws water from the water tank through the water pipe and then sprays the water from the nozzle so that the water is sprayed onto the surface of the coal, thereby removing dust from the coal after the material is turned over, preventing excessive dust from floating in the air and causing harm to the workers, and improving the working environment of the workers. The movement of the L-shaped rod will drive the teeth to move, and the movement of the teeth will drive the gears to rotate. The rotation of the gears will open the valve so that water will be sprayed to reduce dust only when the material turning device turns the coal over, preventing the waste of water resources caused by long-term water spraying, and improving the practicality of the device. The movement of the L-shaped rod will drive the impact block to move, and the movement of the impact block will hit the nozzle. The nozzle will vibrate after being hit, and the vibration of the nozzle will cause the water to be sprayed to a larger range, further improving the dust reduction effect and further improving the working environment of the workers.
