The corrugated sidewall belt conveyor is generally composed of the driving drum, corrugated sidewall belt, head shield and discharge bucket, which is the conveying equipment often used in the conveying process of powder material at present. In the process of operation, when the belt transports viscous materials, some viscous materials always run with the corrugated sidewall belt, which causes the materials to continue to run with the belt and wastes the cost of raw materials, which will directly affect the service life of belt as time passes. Moreover, when the material accumulation is more, it will make the corrugated sidewall belt can not run normally, even lead to the shutdown.

During the operation of the corrugated sidewall belt conveyor, a vibration sweeper is adopted on the non-working face of the corrugated sidewall belt. When the roller of the vibration sweeper rotates, the roller strikes the non-working surface of the belt, so that the belt vibrates and the remaining miscellaneous materials stuck to the working surface of the belt vibrates to fall down. However, when the conveyor is transporting the material with greater viscosity, it is often unable to beat the remaining material by this vibration way. Another solution to this problem is that during the operation of the conveyor, the material is located on the outer surface of the corrugated sidewall belt, which drives the corrugated sidewall belt through the rotation of the driving drum to realize the material transportation. When the material into the head cover, due to the effect of its weight of the material, as well as the tangential velocity resulting from the movement of the material along the corrugated sidewall belt, which affect the majority of the material falling off the corrugated sidewall belt into the discharge funnel, and a small part of the material continues to move along with it because it sticks to the corrugated sidewall belt, which cannot be recycled and reused, thus seriously wasting the material.
In order to solve the problems raised above, the discharge port device of the corrugated sidewall belt conveyor can be reformed, which consists of the corrugated sidewall belt, the driving drum, the head cover and the discharge funnel. The corrugated sidewall belt goes around the driving drum, and the head cover is installed at the outer end of the driving drum. The discharge funnel is installed at the lower end of the head cover, and a bracket is installed on the inclined end of the head cover. A pulley is installed on the bracket, and the pulley is in contact with the outer surface of the corrugated sidewall belt. This kind of discharge port device can save the cost of raw materials and recover the materials on the outer surface of the corrugated sidewall belt, which has the characteristics of automatic operation, high reliability and strong practicability.
Through specific methods to achieve material shedding, during the operation of the conveyor, the material is located on the outer surface of the corrugated sidewall belt, which drives the corrugated sidewall belt through the rotation of the driving drum to realize the material transportation. When the material into the head cover, due to the effect of its weight of the material, as well as the tangential velocity resulting from the movement of the material along the corrugated sidewall belt, which affect the majority of the material falling off the corrugated sidewall belt into the discharge funnel, and a small part of the material continues to move along with it because it sticks to the corrugated sidewall belt. When the movement to a border of pulley, as a result of pulleys and corrugated sidewall belt with relative motion, and the outer surface of the roller tooth surface, which makes the viscous material fall down from corrugated sidewall belt, the fallen materials fall back into the discharge funnel, realizing the material recovery and utilization, thus saving the material cost and improving the operation efficiency of the corrugated sidewall belt conveyor.
