Buffering material-receiving device for coal mine

Abstract

The invention discloses a buffering material-receiving device for a coal mine. The discharging end of a first conveyer (44) is connected with a buffering device (2), a buffering carrying roller (10) is arranged at the position, aligned to the outlet of the buffering device (2), of a second-conveyer tail portion (7), a rear stopping device is arranged at the rear end of the second-conveyer tail portion (7), a left stopping device (3) is arranged on the left side of the second-conveyer tail portion (7), a right stopping device (4) is arranged on the right side of the second-conveyer tail portion (7), a hopper-shaped structure is formed by the rear stopping device (1), the left stopping device (3) and the right stopping device (4), one surface of the hopper-shaped structure is open, and the open direction consists with the moving direction of a conveying belt. The buffering material-receiving device for the coal mine is simple in operation, practical, low in maintenance cost, long in service life, and ideal in buffering effect, and prevents material leakage; by means of combination of the buffering device, the stopping devices and the second-conveyer tail portion, materials are effectively buffered, and the problems of leakage and scattering of materials are solved.

Description

technical field [0001] The invention relates to a buffer material receiving device, in particular to a coal mine buffer material receiving device for a belt loader and a roadheader. Background technique [0002] At present, the buffer feeding device used in coal mines mainly absorbs the impact energy of falling materials through the buffer roller group. The buffer rollers include rigid rollers, buffer rollers covered with rubber rings, flexible rollers, and buffer rollers covered with air cushion rings. , flexible rollers and elastic rollers. Among them, the best performance is the buffer roller with air cushion ring, but this kind of buffer roller has high cost, high maintenance cost during use, and short life, so it is not suitable for many; the buffer roller with rubber ring can only absorb The impact energy of the falling material is very small; the cushioning effect of the elastic idler roller is good, but its winding degree is unstable, and the tape wears seriously, a...

Problems solved by technology

Among them, the best performance is the buffer roller with air cushion ring, but this kind of buffer roller has high cost, high maintenance cost during use, and short life, so it is not suitable for many; the buffer roller with rubber ring can only absorb The impact energy of the falling material is very small; the cushioning effect of the elastic idler roller is good, but its winding degree is unstable, and the tape wears seriously, and when the tape adopts mechanical joints, the tape clip is easy to get stuck between the spring rings, causing the tape to tear ; The cushioning effect of the flexible idler is better, but the service life of its radial shaft is not high, and the idler has a certain displacement along the material direction, which increases the running resistance
