Description

Container tipper powder unloading equipment and flexible hopper mechanism thereof

Technical Field

The utility model relates to the technical field of powder pneumatic conveying, in particular to a telescopic hopper mechanism. In addition, the utility model also relates to powder unloading equipment of the container dumper, which comprises the telescopic hopper mechanism.

Background

At present, dry bulk cargo is loaded in the field of transportation and packaging, and the problems of environmental pollution and repeated transfer loading and unloading exist in common shipping and transportation, so that bulk cargo is greatly changed into whole cargo.

The situation that the powder and granular materials with the packaging bags are transported by small bags and ton bags is gradually reduced; the main problems are high packaging cost, high loading and unloading cost and long transportation period.

In the standard container bulk transportation, a sea bag is adopted, and hundreds of small bags or dozens of tons of bags are changed into a large container lining bag. Therefore, the packaging cost and the loading and unloading cost can be greatly reduced, and the water channel, the road and the railway are all penetrated.

Modern logistics container transportation is increasingly widespread. Commercial tenants and factories (factories) at two ends of a logistics chain adopt containers to feed and discharge materials, the quantity and frequency of the materials are increased or decreased, and the system is widely applied to various industries such as flour, grains, feeds, chemical industry, lithium batteries and the like.

The container dumper can meet the actual requirement of a client for 'door to door'; moreover, the container turning function is provided for unloading, so that the application of the container turning device in the field of medium and short distance powder conveying is increased day by day.

The powder is the combination of powder and granular materials. Generally speaking, most of powder and granular materials can automatically enter a receiving hole such as a pit and the like by gravity blanking under the condition that a container inclines at a certain angle; such as corn, soy, coal, and the like.

Under the condition that an underground storage bin is not available, the container dumper stops on the ground, materials cannot be conveyed to a high-level storage bin on a client site, and a material loading, unloading and conveying task can be finished only by a special unloading device.

On the other hand, the flowability of many materials in the powder materials is general, and the whole unloading work is difficult to complete only by the downward movement of gravity formed by an inclination angle; such as flour, clay, zinc oxide, etc.

However, the existing container powder unloading device has the following disadvantages: the discharging hopper, namely the sheath body, of the container powder discharging device is a rigid hopper made of stainless steel and the like, and in the initial discharging stage, particularly the intermediate discharging stage, as the frictional resistance between materials formed by the structural characteristics of the discharging hopper and the positions of the discharging hopper is gradually increased, the discharging blockage condition is often generated, and the material flow is restricted; the whole set of unloading device and the container are rigidly connected to form a whole body and are attached and hung on the container, so that the fall of gravity blanking is limited, and smooth unloading of the container is not facilitated.

In conclusion, how to improve the problems of the prior art, such as the disadvantages of the powder unloading device of the container dumper, is a problem that needs to be solved urgently by technical personnel in the field.
