Description

Removing device of fallen coal using excavator

The present invention relates to a device for removing a grenade using an excavator, and more particularly, to install a grenade generated by a drop of a grenade when the belt is transported in a low coal yard, which is installed on an excavator that is moved and moves along with an excavator. The present invention relates to a device for removing a rock using an excavator capable of effectively removing the rock by operating.

Thermal power generation accounts for about 60% of Korea's electricity production, more than hydropower or nuclear power. Fuels of domestic thermal power generation include bituminous coal, anthracite coal, internal combustion, LNG-composite, diesel and bunker C oil, among which bituminous coal power plants are responsible for base loads (basically used power) and peak loads with LNG-combined thermal power. It is common to take charge of (power when using the most power).

The advantage of thermal power plant is that its structure is simpler than nuclear power plant, its construction cost and construction time are short, and its thermal efficiency is excellent because it is directly heating the boiler.

Bituminous coal, one of the fuels used in boilers, corresponds to anthracite coal, which contains a large amount of volatile components and burns with flame when burned. Examples of bituminous coal include peat, peat, lignite, bituminous coal, and the like, and are mainly used for power generation due to high calorific value.

There are many ways to transfer coal to a boiler, but the conveyor system using belts is mainly used.

Such a belt conveyor is a device for circulating a belt made of rubber, fabric, wire mesh or steel plate, and placing various transport items on the belt, and continuously transporting the belt conveyor. The belt conveyor is driven by rotating the pulley with a pulley. One belt length can be up to about 2,000m when horizontal, and a device for preventing sagging along the way is also provided.

The belt conveyor is supplied to a generator in a coal-filled low coal yard, and is installed to transport long distances while being exposed to the outdoors. Therefore, the coal loaded on the upper part of the belt conveyor is separated from the belt conveyor under the influence of self vibration and wind, accumulated on the ground, and exposed to the outdoors, and is fixed at the upper part of the belt under wet conditions such as rain and snow when the coal moves. When moving out of the supply position and moving downwards, a grenade was built up to the ground by gravity.

Such a grenade may accumulate on the lower ground where the belt conveyor is installed, and if the height exceeds a certain height, it may come into contact with the belt conveyor driving device or the belt, causing a failure of the belt conveyor, or causing an overload of the belt. Since the coal is itself made of coal material with a low ignition point, it is necessary to continuously remove the rock as it may be ignited by rising temperature or irradiated solar heat.

In general, in order to remove the grenade, during the operation of the belt conveyor, the worker enters the lower part of the belt to remove the grenade by hand, or the excavator is removed using an excavator while the belt conveyor is stopped. When the above-mentioned worker removes the grenade by hand, the work speed is slowed, and there is a problem that the injury occurs in contact with the moving belt.

In addition, when using an excavator, when the bucket of the excavator comes into contact with the belt during the deciduous operation, the belt conveyor may be damaged, so that the deciduous can be removed only in an inaccessible area. There was a problem that the efficiency of removal is reduced as it can be removed at a height below the height of the belt is prevented in the stopped state.

In recent years, a rock coal removal device has been disclosed to easily collect a rock coal generated by installing an iron plate on a lower surface of a belt conveyor or by installing a lower ash ash collecting conveyor.

However, in the prior art, the rock removing device has to be installed over the entire belt moving surface of the belt conveyor, so that the cost is increased and management is difficult.

In particular, in the case of iron plate, the worker must go through the collection work while the belt conveyor is installed over the entire moving distance, and as the moving distance of the belt conveyor becomes longer, the installation length becomes longer and the cost increases. There was an increasing problem.

In addition, when the collection conveyor is installed at the bottom, a wider conveyor than the belt conveyor should be installed to remove the falling coal from the side of the conveyor for moving coal, and the overall conveyor should be installed at the lower part over the entire moving distance of the belt conveyor. As the installation cost is increased, and the grenade on the lower collection conveyor is installed outdoors, the rocket removal efficiency is lowered due to the secondary occurrence of the grenade due to the occurrence of the grenade.

The present invention has been invented to improve the above problems, the problem to be solved by the present invention, is installed on a movable excavator while providing a hydraulic pressure is moved with the excavator while being provided with power from the excavator belt to transfer coal The present invention provides an apparatus for removing a camel using an excavator that can improve the efficiency of removing the camel by reciprocating the bottom of the conveyor.
