DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Please refer to Figures 1-6 The present application provides a technical solution:

[0027] Embodiment one:

[0028] A kind of sampling device for mine air quality detection, including chassis 1 and universal wheel 2, and the upper portion of chassis 1 is provided with sampling structure;

[0029] Sampling structure includes sampling mechanism 3 and adjusting mechanism 4;

[0030] Sampling mechanism 3 includes sampling box 301, bearing plate 302, two-way threaded rod 303, threaded plate 304, clamping plate 305, the inner wall of sampling box 301 is connected with the both ends of bearing plate 302, the inner wall of sampling box 301 is rotationally connected with one end of two-way threaded rod 303, the outer wall of two-way threaded rod 303 is screw connected with the inner wall of threaded plate 304, the top of threaded plate 304 is connected with the bottom of clamping plate 305, clamping plate 305 one side extrusion clamping has sampler 306, sampling box 301 one side is connected with wind collector 307, sampling box 301 inner wall extrusion contact has filter screen 308, sampling box 301 inner wall is fixedly installed with connecting plate 309, the inner wall of connecting plate 309 is screw connected with threaded rod 310, one end of threaded rod 310 is rotationally connected with extrusion plate 311, sampling box 301 inner wall is fixedly installed with fixed plate 312, and fixed plate 312 top is fixedly installed with air extractor 313;

[0031] In this embodiment, the number of threaded plates 304 is two, and the threaded plates 304 are symmetrically distributed on the outer wall of the bidirectional threaded rod 303, respectively. The shape of the threaded plate 304 is U-shaped, and the moving groove is formed on one side of the bearing plate 302. The outer side of the threaded plate 304 is slidably connected with the inner side of the moving groove, so that the position of the two clamping plates 305 can be quickly and conveniently adjusted, and the sampler 306 can be quickly and conveniently disassembled and assembled.

[0032] Further, the number of clamping plates 305 is two, and the clamping plates 305 are symmetrically distributed on both sides of the sampler 306, respectively.

[0034] In use, when sampling and detection work is needed, the operator moves the device to the desired position through the universal wheel 2, adjusts the height of the device by starting the adjusting mechanism 4, and then performs sampling work at different heights. When sampling work is needed, the external air is sucked into the sampling box 301 through the air collecting cover 307 by starting the air extractor 313, the external air can be better collected by installing the air collecting cover 307, and the air entering the sampling box 301 through the air collecting cover 307 can be filtered by the filter screen 308.

When the filter screen 308 needs to be disassembled and assembled, the threaded rod 310 is moved in the connecting plate 309 by rotating the threaded rod 310, the extrusion plate 311 is moved by the movement of the threaded rod 310, the limiting and fixing of the filter screen 308 are cancelled by the movement of the extrusion plate 311, and then the filter screen 308 can be taken out of the sampling box 301. When installation is needed, the above steps are repeated in reverse, so that the sampling work can be better performed, and the impurities in the air can be better filtered.

[0037] In this embodiment, the number of guide rods 404 is four, and the guide rods 404 are symmetrically distributed on the inner wall of the adjusting box 401, and the number of reinforcing plates 407 is two, and the reinforcing plates 407 are symmetrically distributed on both sides of the adjusting box 401, so that the height of the sampling box 301 can be quickly and conveniently adjusted, and different height air can be better sampled.

[0038] Further, the bottom of the chassis 1 is connected with the top of the universal wheel 2, the top of the chassis 1 is connected with the bottom of the adjusting box 401, and the bottom of the sampling box 301 is connected with the top of the mounting plate 406.

[0039] In use, when sampling work needs to be detected, the operator moves the device to the required position through the universal wheel 2, drives the adjusting plate 403 to slide on the guide rod 404 by starting the electric telescopic rod 402, so as to effectively increase the stability of the adjusting plate 403 when sliding, drives the supporting rod 405 to move by sliding the adjusting plate 403, drives the mounting plate 406 to move by moving the supporting rod 405, drives the sampling box 301 to move by moving the mounting plate 406, so as to better sample different height air, and the reinforcing plates 407 installed on both sides of the adjusting box 401 can increase the supporting strength of the adjusting box 401, so as to better perform sampling work, and further improve the working efficiency of the sampling device.

[0040] It is to be noted that, as used in this specification and the appended claims, the singular forms "a," "an" and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a component" can include a combination of two or more components. Similarly, the terms "one" and "the" do not exclude the presence of more than one item, unless the context clearly indicates otherwise. Further, the terminology "an" and "one" are used in the detailed description and claims only to mean one or more, at least one, or "at least one." Finally, the words "comprise," "comprises," and "comprising" and the like, are to be construed in their broadest, intended, and open ended form to encompass events that would otherwise prevent a process, method, article, or apparatus from being encompassed by the specification.
