The movable door 124 on the shielding cabinet 120 can be disassembled, assembled and moved left and right, the handle 1202 is arranged on the movable door 124, the movable door 124 can be opened or closed according to the direction a of the movable door, the lifting hole 1204 is arranged on the movable door 124, and the guide wheel 1248 is arranged at the lower end of the movable door, so that the equipment installation and the taking and placing of articles by people in and out of the shielding cabinet 120 are facilitated.
In summary, the beneficial effects according to the embodiments of the present invention are:
1. the shielding cabinet 120 can automatically intercept and clean the float coal at the tail 200 without manual cleaning, thereby reducing the labor intensity and labor cost of workers and avoiding the injury of personnel caused by manual cleaning of the float coal.
2. The shielding cabinet 120 has a receiving space 1222 for storing daily tools and small accessories, so that the maintenance of the equipment is more convenient and the maintenance efficiency of the worker is greatly improved.
