Material Handling Hoppers and Material Handling Systems

Abstract

The invention relates to the field of material conveying and discloses a material conveying hopper and a material conveying system. The material conveying hopper (1) is provided with a conveying channel (4) with a feed port (2) and a discharge port (3), an arc surface (5) extending towards the discharge port (3) is formed at the position, close to the discharge port (3), of the conveying bottom surface of the conveying channel (4), the concave part of the arc surface (5) faces the conveying channel (4), the kinetic energy of material can be changed, the impact energy can be lowered, the falling speed of the material can be lowered, the speed at a material outlet and the speed of a conveying belt in the conveying direction are nearly uniform, and therefore abrasion between the material and the conveying belt caused by reacceleration of the material is reduced and the energy consumption of operation of the conveying belt is reduced.

Description

technical field [0001] The invention relates to the technical field of material conveying, in particular to a material conveying hopper and a material conveying system. Background technique [0002] At present, in the process of material transfer, in order to increase the transfer volume and improve the transfer efficiency, conveyor belts are usually used for long-distance transportation. Correspondingly, the material is transported to the running conveyor belt through the receiving hopper. [0003] The receiving hopper used in the known bulk material transfer is a cuboid structure composed of four vertical side plates. This kind of hopper is located above the conveyor belt and arranged obliquely relative to the conveyor belt, that is, the material flow direction in the hopper and the belt conveying direction form an included angle of 70-90°. Although this kind of hopper can carry out the transfer and delivery of materials to meet the transfer needs, it also has certain de...

AI Technical Summary

Problems solved by technology

[0004] First of all, the material cannot be collected, guided and buffered effectively, and the material will directly impact the conveyor belt, causing the wear of the conveyor belt;

[0005] Secondly, the material conveyed by the hopper will directly impact on the conveyor belt, and the speed of the material in the near vertical direction will drop to close to zero. In this way, after the material falls on the conveyor belt, it needs to be re-accelerated to obtain the same speed as the conveyor belt. This increases the wear of the conveyor belt and increases the energy consumption of the conveyor belt operation;

[0006] Finally, due to the direct impact of the material on the conveyor belt, the conveyor belt is vibrated, which causes the material to deviate when loaded, and there are many problems such as obvious material scattering and serious dust.
