[0002] A belt conveyor is a mechanical device that continuously transports materials. Traditional belt conveyors are often used to load materials from the end point of the belt conveyor and transport them to the end point for unloading. However, the disadvantage is that during the transportation of bulk materials, the conveyed materials cannot be unloaded at one or more points along the conveyor belt. Traditional belt conveyors often deviate from the conveyor belt due to various reasons during use. The consequence of conveyor belt deviation is accelerated wear or tear of the conveyor belt, resulting in shutdowns, which not only brings economic losses to the company but also causes work-related accidents. There is currently no good solution. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations. Specific embodiment:

[0029] See also Figure 1-6 ,

[0030] This solution has the following working process: during normal use, the composite roller is in a concave state under the pulling action of the push rod, the conveyor belt rolls forward on the composite roller, the two long rollers tilt inward at the same time, and the short roller is lower than the two ends of the long roller, causing the conveyor belt to form a groove, which can increase the conveying capacity of the conveyor belt and achieve the purpose of stockpiling materials. The amount of stockpiled materials can be adjusted by adjusting the depth of the groove by the push rod;

[0031] When the weight of the conveyed material is unevenly distributed on the conveyor belt, the conveyor belt will deviate to the left or right. For example, when the conveyor belt deviates to the right, the contact area between the long roller on the right side of the composite roller and the deviated conveyor belt increases, and the friction resistance also increases. The long roller on the side with increased friction resistance forces the revolving gantry to rotate in the direction of travel of the conveyor belt. The inward-tilted long roller forces the deviated edge of the conveyor belt to rise, forcing the weight of the material to shift to the center of the conveyor belt. The friction resistance of the conveyor belt is also transferred to the side with smaller friction resistance. Finally, the friction resistance reaches a balance, so that the conveyor belt automatically corrects the deviation to ensure smooth operation of the conveyor belt.

[0032] When it is necessary to unload at a certain point in the middle, the push rod pushes the outer end of the long roller shaft. Under the lever action of the hinge bracket, the short roller connected in the middle of the two long roller shafts is lifted upward. In order to prevent the short roller from deviating in the forward direction of the conveyor belt under the friction resistance of the conveyor belt, the positioning guide mechanism restricts the short roller, allowing only the short roller to move up and down but not forward and backward, so that the conveyor belt forms an arc-shaped bulge. The material pours and slides under the action of gravity to achieve fixed-point unloading. The mid-unloading point can be automatically formed by controlling the push rod. Such reciprocating can achieve repeated unloading at this fixed point. The unloading guard plate at the unloading position can limit the scattering of bulk material and has a good effect of protecting the environment.

[0033] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.
