Abstract

The invention discloses a coal mine quality detection device, which comprises a pulverizer, and the pulverizer comprises: a shell, which is internally equipped with a grinding bowl, and is provided with a spray head and a blast pipe on the top surface; a grinding block, which is located above the grinding bowl, and has a top face sinking downwards to form a cavity, wherein the cavity is fixedly connected with an elastic rod and provided with at least one circle of spraying holes in a penetrating mode, and a first electromagnet is arranged at the top of the side wall of the cavity; a first driving mechanism, which is arranged on the outer side of the top of the shell, drives the grinding block to rotate along the horizontal plane and vertically move up and down, and is externally equipped with a second electromagnet; a blocking piece, which comprises a plurality of hole plugs, wherein any hole plug is fixedly provided with a connecting rod, the connecting rod is connected with a sieve tray, a third electromagnet is arranged on the top surface of the sieve tray, the bottom surface of the hole plug horizontally extends to form an abutting edge, and a spring is further arranged betweenthe sieve tray and the bottom surface of the cavity. A coal mine sample can be automatically cleaned after being ground, and the influence on the detection result of a next ground coal mine sample isavoided.

Description

Technical field[0001]The present invention relates to the field of coal quality detection. More specifically, the present invention relates to a coal mine quality detection device.Background technique[0002]Coal mine quality assays generally include four links to sample, sample, injection and analysis test, that is, first take the coal mine that needs to be detected, ground the coal mine into powder coal powder, weigh the weight of the coal required. The detection in the detection instrument is placed, and the quality of the coal mine is identified according to the data obtained.[0003]At present, the machine for pulverizing the coal mine sample does not have an automatic cleaning device. Since the coal mine has viscous, the sample remaining in the machine will affect the detection result of the next sample.Inventive content[0004]It is an object of the present invention to address at least the above problem and provide at least the advantage will be described later.[0005]It is also an...
