[0003] In order to make the signal receiving device receive the signal better, the signal receiving device is generally installed at a high place. The existing signal receiving device has two major defects when in use: 1. It is inconvenient to clean dust and snow. Since a large amount of dust will be generated during mining, the dust is easily accumulated on the signal receiving device, affecting the reception of the signal. In addition, when it snows, the snow covering the signal receiving device will also affect the reception of the signal; 2. The buffering performance is poor. Strong winds are prone to occur in mines, which can easily blow down the signal receiving device. Therefore, in view of the above situation, it is urgent to develop a signal receiving device for mine communication that is easy to clean dust and snow so as to maintain the performance of the signal receiver, has good buffering performance, and is not easy to tip over, so as to overcome the shortcomings in current practical applications and meet current needs.

A chassis 4 is fixed on the support frame 1, and a dust-cleaning and snow-removing mechanism 5 extending to the outside thereof for cleaning the signal receiver body 3 is installed in the chassis 4. A left-right swinging mechanism 6 for driving the dust-cleaning and snow-removing mechanism 5 to swing is installed on the top of the support frame 1. When encountering strong winds, the impact caused by the wind is absorbed by the buffer mechanism 2 to prevent tipping. When a lot of dust or snow is accumulated on the signal receiver body 3, the dust or snow accumulated on the signal receiver body 3 is blown away by the dust-cleaning and snow-removing mechanism 5.

[0021] The dust and snow removal mechanism 5 includes: a high-pressure fan 501, a spiral tube 502, an electric heating rod 503, a shunt pipe 504, a hose 505 and a blowing nozzle 506.

When removing snow, the blowing nozzle 506 blows out a high-pressure airflow to blow away the snow on the surface of the signal receiver body 3, and then the electric heating rod 503 heats the airflow passing through the spiral tube 502, and then the hot air melts the frozen snow on the signal receiver body 3. In addition, when the blowing nozzle 506 is blowing, the driving motor 601 drives the first gear 602, the second gear 603 and the transmission shaft 604 to rotate, and the rotation of the transmission shaft 604 drives the diverter pipe 504 and the blowing nozzle 506 to rotate, thereby expanding the blowing range of the blowing nozzle 506; when encountering strong winds, the support frame 1 shakes, and the shaking of the support frame 1 drives the connecting rod 202 to move, and the movement of the connecting rod 202 drives the spring 203 to deform, thereby buffering the impact brought by the wind and preventing tipping.
