Detailed Description

The utility model will be further described with reference to the accompanying drawings and specific embodiments. It is to be understood that these examples are illustrative of the present utility model and are not intended to limit the scope of the present utility model. Further, it will be understood that various changes or modifications may be made by those skilled in the art after reading the teachings of the utility model, and such equivalents are intended to fall within the scope of the utility model as defined herein.

The embodiment provides a partition type coal material check device for a guide chute, which is mainly used for preventing massive coal materials from flowing back in the transportation process of water coal.

Referring to fig. 1 and 2, the partition type coal check device for a guide chute according to the present embodiment mainly includes a guide chute 1, wherein the guide chute 1 is used for conveying coal by an internal conveyor belt. In the specific implementation manner that this embodiment provided, the check structures set up 2 groups of the diagram altogether, and the interval of 2 groups is 1.5mm, increases according to the actual demand.

The backflow prevention of the massive coal materials is realized when the water coal is conveyed in the guide chute 1 through a plurality of groups of check structures. Specifically, in the present embodiment, the check structure mainly includes the support rod 3 and the check plate 2. Wherein bracing piece 3 adopts a metal round bar, spanes baffle box 1 setting, and bracing piece 3 both ends are fixed on the two lateral walls of baffle box 1, and non return plate 2 upper portion and bracing piece 3 normal running fit, non return plate 2 bottom and the conveyer belt contact in the baffle box 1, and non return plate 2 inclines towards coal material direction of delivery setting. The whole inclination that is of non return board 2 sets up, upper portion free rotation, lower part and conveyer belt contact, in the coal material transportation process, the coal material promotes the non return board 2 and overturns the back through non return board 2 position and carry, under non return board 2 self gravity effort, non return board 2 presses in conveyer belt coal material top, when the large lump coal material wants to flow back, the back is towards the application of force to non return board 2, because of non return board 2 slope setting, non return board 2 bottom and conveyer belt contact, so non return board 2 can not be overturned past, consequently prevented the backward flow of large lump coal material.
