Description
Technical Field
[0001] The utility model relates to the technical field of reducers, in particular to a reducer for coal detection. Background Art
[0002] The reducer is used to manually reduce the sample volume for preparing and analyzing coal samples. Generally, it is necessary to reduce the minimum sample volume. When using the reducer, coal particles need to be poured from the upper feed port and swung back and forth during the pouring process so that the coal sample is evenly fed into the grid of the reducer in the form of coal flow. This is more troublesome and inconvenient. Utility Model Content
[0003] The utility model provides a reducer for coal detection, which does not require manual swinging of the coal sample, and is more convenient.
[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] Through the above scheme, the coal particles can be poured into the reducer body through the lower hopper. At this time, the stepper motor can drive the threaded rod to rotate clockwise first, then counterclockwise, and repeat this cycle, so that the slider can move back and forth in the slide groove, thereby driving the mounting plate and the reducer body to move back and forth, so that the coal particles can be evenly sprinkled into the grid groove in the reducer body. There is no need to manually swing the coal sample back and forth, which is more convenient. After the coal sample is diverted, the coal particles fall into the two collection boxes under the reducer body, which will raise a certain amount of coal dust and affect the surrounding air environment. The dustproof cover can suppress the rapid diffusion of coal dust, and at the same time, the air in the dustproof cover can be blown out to the outside in conjunction with the dustproof fan, and the dustproof bag is used to filter the airflow to intercept the coal dust, thereby protecting the surrounding air environment.
[0007] Preferably, an opening is provided on one side outer wall of the dustproof shell, a vertical groove is provided on one side outer wall of the dustproof shell, a vertical block is slidably connected to the inner wall of the vertical groove, and a door panel is fixed to one side outer wall of the vertical block.
[0008] With the above solution, after one reduction is completed, the door panel can be pulled upward to expose the opening, and the two collection boxes containing coal particles under the reducer body can be taken out.
[0009] Preferably, a limit frame is fixed on the top outer wall of the reducer body.
[0010] The above solution can prevent the coal particles in the lower hopper from being scattered outside the reducer body.
[0011] Preferably, the dustproof cloth bag is fixed to the air outlet pipe by a clamp.
[0012] Through the above solution, the installation of the dust bag is completed.
[0013] Preferably, fixing holes are provided at four corners of the outer wall at the top of the base plate.
[0014] The above solution makes it easy to fix the substrate.
[0015] Preferably, an air inlet hole is opened on an outer wall of one side of the dustproof shell.
[0016] Through the above solution, the dustproof fan can blow the air in the dustproof shell out to the outside.
[0017] Preferably, the stepper motor and the dustproof fan are both connected to a control switch via a wire, and the control switch is connected to an external power supply via a power line.
[0018] Through the above solution, the stepper motor and the dust-proof electric fan can be powered on and run.
[0019] The beneficial effects of the utility model are:
[0020] The coal particles can be poured into the reducer body through the lower hopper. At this time, the threaded rod can be driven by the stepper motor to rotate repeatedly, so that the slider, the mounting plate and the reducer body can move back and forth, so that the coal particles can be evenly sprinkled into the grid grooves in the reducer body. There is no need to swing the coal sample back and forth manually, which is more convenient. After the coal sample is diverted, a certain amount of coal dust will be raised. The dustproof cover can suppress the rapid diffusion of the coal dust. At the same time, the air in the dustproof cover can be blown out to the outside with the help of a dustproof fan, and the dustproof bag is used to filter the airflow to intercept the coal dust, thereby protecting the surrounding air environment.
