Material scattering prevention device of material piling and taking machine

Abstract

The invention discloses a material scattering prevention device of a material piling and taking machine. The material scattering prevention device is characterized in that the material scattering prevention device comprises an adjustment assembly and a carrier roller assembly, wherein the adjustment assembly comprises steel wire ropes, carrier roller brackets, pulleys and counter weights; the carrier roller brackets are fixed to a trailer main beam; the pulleys are rotationally mounted at the upper parts of the carrier roller brackets; the steel wire ropes strides across the pulleys; the two ends of the steel wire ropes are fixed to the counter weights and the carrier roller assemblies respectively; and the counter weights and the carrier roller assemblies move up and down according to the quantity of materials on a conveying belt and stops moving till force balance. By controlling a distance between belt holding carrier rollers and a carrier roller, the activity space of the conveying belt is controlled, the vibration range of the conveying belt is reduced, and the material scattering quantity is reduced accordingly.

Description

technical field [0001] The invention relates to the field of special equipment for loading and unloading bulk materials, in particular to an anti-scattering device for a stacker and reclaimer. Background technique [0002] The stacker-reclaimer is an advanced and efficient bulk material handling equipment, which is used to load and unload bulk materials such as coal and ore, and is widely used in basic industries such as electric power, metallurgy, mining and transportation (port and wharf). As an important part of the stacker-reclaimer, the tail car plays the function of transferring the materials on the ground conveyor belt to the machine and the stockyard. The conveyor belt is supported by rollers. During the operation of the conveyor belt, the conveyor belt is easy to float and break away from the rollers, resulting in material spillage. It is necessary to install a belt pressing device to prevent the conveyor belt from floating. [0003] Existing belt pressing device 2...

AI Technical Summary

Problems solved by technology

[0004] Although the stacker-reclaimer with a belt pressing device has improved the problem of material spreading to a certain extent, due to the relatively large space between the idler roller and the belt pressing roller, the conveyor belt is easy to vibrate when feeding the conveyor belt, causing the material to remain Can spill, creating additional material cleanup and safety hazards
