Combined grab bucket with multiple storage-variable plates

Abstract

The invention relates to a combined grab bucket with multiple storage-variable plates. The combined grab bucket comprises two bucket bodies symmetrically arranged in the horizontal direction, and an on-off drive mechanism, wherein the upper ends of the two bucket bodies are hinged to each other, and the two bucket bodies are driven by the on-off drive mechanism to complete the start-up movement, the shut-down movement and the material grabbing movement. The combined grab bucket is characterized in that each bucket body comprises a bucket bottom plate and bucket side plates, the bucket bottom plate straightly extends backward from the bucket bottom cutting edge position, the rear portion of each bucket body is transparent, an installation frame is arranged at the lower end of the rear portion of each bucket body, and the movable and detachable storage-variable plates are arranged on the installation frames. The combined grab bucket is simple, compact and reasonable in structure. The detachable storage-variable plates are arranged on the bucket bodies, and therefore the large-span storage change of the grab bucket can be achieved. The combined grab bucket can be used for grabbing materials which include ore, coal and the like and are greatly different in specific gravity, the work efficiency is improved, and the device cost is reduced.

Description

technical field [0001] The invention relates to a multi-block variable capacity plate combined grab bucket, which belongs to the technical field of lifting and unloading equipment. Background technique [0002] Double flap grabs are mainly used in cargo terminals, port machinery plants, power plants, shipyards, steel mills and other industries to grab various bulk cargo. If the grab bucket does not have a variable bucket capacity structure, it cannot be used universally among materials with different specific gravity when grabbing materials. For example, when grabbing small specific gravity materials with a grab bucket that grabs large specific gravity materials such as ore, the efficiency is very low, and when grabbing large specific gravity materials with a grab bucket that grabs small specific gravity materials such as coal, it will be seriously overloaded.

If the grab bucket does not have a variable bucket capacity structure, it cannot be used universally among materials with different specific gravity when grabbing materials

For example, when grabbing small specific gravity materials with a grab bucket that grabs ore and other large specific gravity materials, the efficiency is very low, and when using a grab bucket that grabs small specific gravity materials such as coal to grab large specific gravity materials, it will be seriously overloaded.

[0003] The existing ordinary variable capacity grab structure is to cut off a section at the end of the original grab bottom plate, and then add a detachable plate to achieve the effect of variable capacity. Such a variable capacity structure has a very small span and can only To achieve the purpose of variable volume between materials with similar specific gravity, it cannot be used to grab coal, ore and other materials with widely different specific gravity at the same time, otherwise it will cause serious overload or low efficiency

Coal scuttle and ore need two types of grab buckets to grab separately, which increases the cost
