Self-unloading type material shifting and transporting hopper

Abstract

The invention provides a self-unloading type material shifting and transporting hopper and belongs to the technical field of material storage or transportation devices. The self-unloading type material shifting and transporting hopper comprises a hopper body with the lower portion of a conical structure. A guide support is arranged in the hopper body. A suspension rod penetrates the center of the guide support movably. A suspension ring is arranged at the top end of the suspension rod, and a plug is arranged at the lower end of the suspension rod. A frustum-shaped through hole is formed in a base plate of the hopper body, and the plug is matched with the frustum-shaped through hole so as to seal the hopper body. The self-unloading type material shifting and transporting hopper is novel in structure and reasonable in design; and by researching the falling character of materials, the hopper is subjected to a series of structural improvements in consideration of material airtightness, operation convenience, operation efficiency and the like of the hopper, so that loading and unloading are more convenient, the material airtightness is better, operation is safer and more reliable, the operation efficiency is improved, and the labor intensity is relieved.

Description

technical field [0001] The invention belongs to the technical field of material storage or transportation devices, and in particular relates to a self-unloading material transfer hopper. Background technique [0002] As an auxiliary equipment in the conveying system, the hopper plays the role of connecting and coordinating the crane and the belt conveyor system. Usually, the hopper works by relying on the self-weight of the material without power. Its working condition mainly depends on the physical characteristics of the material and the geometry of the hopper. The working condition of the hopper here mainly refers to the flow condition of the material when it is discharged from the discharge port. There are two most common flow conditions, one is the so-called "vertical column flow", the material above the discharge port moves vertically, the material near the bucket wall is stationary or flows slowly, and the center of the upper surface of the material sinks to form a fun...

AI Technical Summary

Problems solved by technology

This utility model can automatically discharge the material under the action of gravity, but because the conical bottom plate occupies a large amount of space in the barrel, the load of the material at one time is too small, and the barrel is open up and down, during the reloading and transfer process, If the conical bottom plate tilts or vibrates slightly, it may cause material leakage

The patent application number 201520341195.6 discloses a self-unloading hopper, including a hopper, a valve stem and a flange ring arranged on the outer side of the lower part of the hopper. The lower part of the hopper is cone-shaped, and the upper part inside the hopper is Two support rods with the same specifications are arranged parallel to the lower position, and each of the two support rods is provided with a guide sleeve at the midpoint position, and the valve stem passes through the two guide sleeves, and is set at the tail of the valve stem. There is a valve plate, and a lifting lug is set on the top of the valve stem. When the valve plate and the flange ring are closed, it just seals the bottom of the hopper. This utility model has fast feeding, high temperature operation, and reliable operation. Strict, to avoid material leakage, the bottom of the utility model uses the valve plate and the flange ring for airtight cooperation, but the area of ​​the valve plate is too large, the material will be affected when it falls, and the working time will be increased
