Description

Traveling shredding and dredging machine

Technical field:

The invention relates to a cleaning device for coal grates under a train coal dumper and a coal grate for an automobile coal yard, in particular to a coal calculation and dredging device.

Background technique:

In enterprises with large coal consumption in industries such as electric power and metallurgy, usually, coal transported into the plant by train or automobile must be screened for the first time through coal grates. In the past, the sundries remaining on the coal grate after screening, such as large pieces of coal, coal gangue, straw ropes, woven bags, etc., were all handled manually. With the development and progress of society, manual cleaning in such a harsh environment can no longer meet the requirements, efficiency and pace of modern production, and manual operation will be replaced by high-efficiency machinery and equipment. As a result, various types of dredgers have emerged. However, these devices are only equipped with crushing teeth, but do not have the function of crushing and cutting. They can only crush some large coal blocks, but cannot crush hard materials such as coal gangue, and cannot clean up flexible debris such as branches, straw ropes, and woven bags ( Sometimes these miscellaneous items are even the main contradiction). And crushing tooth is distributed too much (6) on a circle, and opening size is too small, still can only carry out to large stone, and equipment wearing parts service life is short, uses all not ideal enough, fails to adopt widely. The traveling mechanisms of all existing similar equipment in China rely on the rolling friction between steel wheels (including two-wheel drive or four-wheel drive) and steel rails, which is very easy to slip, especially when there is water, mud or wet on the rail surface. When the coal and the resistance to travel are slightly larger, skidding occurs. At this time, the machine can only stop on the coal grate, unable to advance or retreat, and the dumper cannot normally unload coal. None of the existing domestic equipment is equipped with a hand-operated device. When the machine is slipping or parked or the electrical appliances fail, the machine cannot be returned to the machine room, which affects the operation of the dumper.
