Embodiment Construction

[0022] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the embodiments. Obviously, the accompanying drawings in the following description are some embodiments of the present invention. Ordinary technicians can also obtain other drawings based on these drawings on the premise of not paying creative work.

[0023] Please see Figure 3 to Figure 6 , the embodiment of the present invention provides an ore selective crushing device 10 for the middle section of the underground belt, which is used in conjunction with a down-trough belt conveyor 30, and is arranged in the middle section of the down-trough belt conveyor 30. The down-trough belt conveyor 30 includes Conveyor belt 301, used for ore selective crushing in the middle section of the underground belt. The device 10 includes a screening device 101, a crushing device 102, and a single-b...

Abstract

The invention provides an ore selective crushing device at the middle section of an underground belt, and relates to the technical field of screening and crushing equipment for underground ores. The ore selective crushing device is used in cooperation with a crossheading belt conveyor and is arranged at the middle section of the crossheading belt conveyor. The crossheading belt conveyor comprisesa transportation belt; the ore selective crushing device comprises a screening device, a crushing device and a single-belt two-position transportation device; and the single-belt two-position transportation device comprises a positive bend wheel and a reverse bend wheel. The positive bend wheel and the reverse bend wheel that are opposite in rotation direction are connected onto the transportationbelt of the crossheading belt conveyor, and the transportation belt is combined with the screening device and the crushing device by changing the twice moving directions, so that the transportation belt can not only transport mined ores to the screening device, but also carry small ores passing through the screening device and crushed large ores away at the same time, and when the screening function is added, a screening transfer machine does not need to be added, so that resource waste is relatively reduced.

Description

technical field [0001] The invention relates to the technical field of underground ore screening and crushing equipment, in particular to an ore selective crushing device for the middle section of an underground belt. Background technique [0002] Please also see figure 1 , with the continuous development of the mining industry, underground mining technology continues to be popularized, combined with the continuous advancement of science and technology in recent years, to promote the continuous update and development of underground mining technology, the underground mining face is mined by fully mechanized mining, and the ore is formed into blocks Therefore, it is necessary to add a crusher 40 at the head unloading point of the trough transfer machine 20 and above the trough belt conveyor 30 to transport the massive ore to the crusher 40 for further processing. Crushing, however, the ores collected are of different sizes, and all ores are crushed through the crusher 40, so ...
