[0030] By setting the mesh size of the first screening net 5 larger than that of the second screening net 6, the coal blocks can be vibrated and screened in layers, and the coal block size classification and screening effect is good. The metal screen has high-strength supporting capacity and screening capacity, which increases the practicality of the device.
[0031] Furthermore, the dust cap 7 is a semicircular cap, and the dust cap 7 is transparent;
[0032] By setting the dustproof cover cap 7 as a semicircular cover cap, it is easy to install, has a stable supporting effect, and is transparent, so the coal block screening situation can be observed intuitively, which increases the practicability of the device.
