Problems solved by technology

That is to say, for the dust collected by traditional methods, the authenticity of the dust dispersion degree obtained by the detection is highly variable, and cannot truly reflect the distribution law of the dust dispersion degree of the mining work, so the risk of underground operations is correspondingly increased. sex

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] like figure 1 , 2 , 3, 4, and 5, a downhole dust collection device includes a dust collection unit and a support unit, and the dust collection unit includes a box body 1, a drawing plate 2, a collection tray 3, filter paper, a mechanical timer 4, Rotary damper 5, spring damper 6 and tension spring 7; the support unit includes a support frame 14, and several trays 15 are arranged in the vertical direction of the support frame 14, and the dust collection unit corresponds to the tray 15;

[0027] The drawer plate 2 is arranged in the box body 1, and the drawer plate 2 slides and fits with the box body 1 through the slideway 11; The direction is the same as the sliding direction of the drawing plate 2, and the inner side folding fan of the collecting tray 3 is horizontally fixed on the upper surface of the drawing plate 2; the fi...

Abstract

The invention discloses an underground dust collection device and belongs to the technical field of coal mine dust sampling and collection. A withdrawing plate is positioned in a box body, and the withdrawing plate and the box body are matched with each other in a sliding mode; a collecting disc is in a folded structure and is fixedly arranged on an upper surface of the withdrawing plate; filter paper is positioned on the collecting disc; a rotating shaft in the center of the collecting disc is connected with one end of a rotary damper; the other end of the rotary damper is fixedly connected to the withdrawing plate; a first torsional spring is arranged between the center rotating shaft and the withdrawing plate; the upper end of a pressing block corresponds to the collecting disc, and the lower end of the pressing block is hinged to the withdrawing plate; a second torsional spring is arranged between the pressing block and the withdrawing plate; an ejector rod is arranged in the box body and corresponds to the pressing block; a spring damper and a tension spring are both arranged on the lower surface of the withdrawing plate; the spring damper and one end of the tension spring are fixedly connected with the withdrawing plate, and the other end of the tension spring is fixedly connected to the box body; a mechanical timer is arranged on the box body, and a lock head corresponds to a lock hole in the withdrawing plate. The influence by human factors can be reduced, a phenomenon that the filter paper sways to enable the dust to drop is avoided, and the truth of the detection result of dust dispersity is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of coal mine dust sampling and collection, and in particular relates to an underground dust collection device, which is used for collecting naturally settled dust on an underground mining face of a coal mine. Background technique [0002] As the intensity of coal mine mining increases, the amount of dust in the mining face also increases. A large amount of dust directly endangers the health of underground miners, and the risk of dust explosions also increases. Accurate control of underground mining The degree of dust dispersion in the working face is an important means to avoid the harm of underground dust. [0003] Dust dispersion is an important monitoring index parameter in downhole, and the authenticity of the detection results is very important. The main factor that can affect the detection results of dust dispersion comes from the dust collection process. The most commonly used dust collection method ...
