Special shaped surface coal leveling device and use method thereof

Abstract

The invention provides a special shaped surface coal leveling device and a use method thereof, which belongs to the field of mechanical design, in particular to the technical scheme of the device capable of making the top surface of the coal smooth and uniform through smoothly pushing the coal arranged on a train to side gaps inside a train body and the use method thereof. The invention is characterized in that the device capable of making the top surface of the coal smooth and uniform through smoothly pushing the coal arranged on the train to side gaps inside the train body mainly comprises a special shaped surface coal leveling scrapping plate, a cross beam, an upper coal blocking plate, four groups of pulley mechanisms and a rib plate. The invention uses the mathematical feature of the continuous second derivatives of a special shaped curve surface for making the scrapping plate to present a special shaped surface shape, so the scrapping plate has good fluid dynamics performance, and the forward moving action force of the train is used for smoothly pushing the coal in the middle of the train body to both sides of the train body. Thereby, the efficiency and the quality of the coal loading on the train are improved, and the defects of low speed, high cost, high work intensity and low coal leveling quality of manual auxiliary coal leveling are overcome.

Description

technical field [0001] The invention relates to a special-shaped surface coal leveling device and its use method, which belong to the field of mechanical design, and specifically relate to a device capable of smoothly pushing the coal loaded on the train to the space on the inner side of the carriage, so as to make the top surface of the coal flat and uniform and the technical scheme of the method of use thereof. Background technique [0002] Railway is the main channel for coal transportation. With the increase of train speed and the continuous improvement of energy saving and environmental protection requirements, there are high requirements for the loading quality of coal transport trains. When coal trains are loaded with coal, due to the coal loading method, the coal is piled up in the middle of the carriage and there is less coal in the edge space, so it must be leveled and enriched, that is, the coal piled in the middle of the carriage is discharged to the edge space a...

AI Technical Summary

Problems solved by technology

The effect of scraper leveling depends entirely on the shape of the scraper. The scraper used in current production practice is generally a rectangular scraper, and the scraper surface is a simple plane. This kind of scraper can only perform simple leveling. , the work efficiency is very low and the quality of flat coal is poor

The most obvious problem of this type of coal leveling device is that when the scraper is leveling the coal, the coal cannot be pushed to the two sides of the compartment in time due to the unsmooth coal discharge, so that the coal in the middle of the compartment is still piled up very high and continues to the rear end of the compartment. In the end, it is still necessary to manually fill up the two sides of the compartment; some coal levelers are slightly improved in shape, that is, a pointed protruding part is welded in the middle of the rectangle to facilitate coal discharge, although the coal separation effect has been improved. However, the problem of unsmooth coal discharge cannot be solved fundamentally. It can be seen that if one wants to obtain an ideal leveling coal effect, it is necessary to improve the shape of the scraper of the leveling coal device
