The centrifugal device includes a mounting shaft 41, a rotating lever 42, a weight ball 43, a pressing surface 44, and a torsion spring 45.
With the rotation shaft 3 as an axis, a plurality of installation shafts 41 are installed in the hollow cavity 2 in an annular distribution manner, a rotatable rotation rod 42 is installed on the installation shafts 41, one end of the rotation rod 42 is provided with a counterweight ball 43, the other end of the rotation rod 42 is fixedly provided with an extrusion surface 44, a torsion spring 45 is also arranged on the installation shafts 41, one elastic end of the torsion spring 45 is connected with the installation shafts 41, and the other elastic end of the torsion spring 53 is connected with the rotation rod 42.
As shown in fig. 2, a mounting plate 6 is covered above the hollow cavity 2, the mounting plate 6 is fixedly mounted on the crusher pulley 1 through a plurality of mounting bolts 7, the rotating shaft 3 extends outwards through the mounting plate 6, a fan driving pulley 5 is fixedly mounted at the outer end of the rotating shaft 3, and the fan driving pulley 5 takes the rotating shaft 3 as an axle center.
When the driving belt pulley for the mine dust removing equipment works, the crusher belt pulley 1 is arranged on the driving end of the crusher, then the crusher belt pulley 1 is connected with the belt pulley of the power motor by utilizing the belt, further driving is realized, and then the fan driving belt pulley 5 is connected with the belt pulley of the fan by utilizing the belt.
As shown in fig. 3, when the crusher starts to work, the power motor in the crusher will be started, at this time, the power motor drives the crusher pulley 1 to rotate through the belt installed between the power motor and the crusher pulley 1, the rotation of the crusher pulley 1 will drive a plurality of centrifugal devices inside the hollow cavity 2 to move, and the installation shaft 41, the rotation rod 42 and the weight balls 43 in the centrifugal devices will rotate along with the rotation of the crusher pulley 1. When the centrifugal device rotates, the weight ball 43 in the centrifugal device generates centrifugal force due to rotation, and when the centrifugal force generated by the weight ball 43 can overcome the acting force of the torsion spring 45, the rotating rod 42 and the weight ball 43 generate force close to the crusher pulley 1, so that the pressing surface 44 is close to the wear-resistant lining 31; when the rotation speed of the crusher pulley 1 is increased to the working rotation speed, the extrusion surface 44 can be combined with the wear-resistant bushing 31, at the moment, the extrusion surface 44 drives the wear-resistant bushing 31 to drive the rotation shaft 3 to rotate, the rotation shaft 3 rotates to drive the fan driving pulley 5 to rotate, the fan driving pulley 5 rotates to drive a belt between the fan driving pulley 5 and the fan to move, so that the fan is driven to work, and the fan can carry out dust removal operation on the crusher.

When the crusher stops working, the power motor in the crusher will also stop, at which time the stopping of the power motor will reduce the rotation of the crusher pulley 1 by means of the belt mounted between the power motor and the crusher pulley 1 until the crusher pulley 1 stops. The reduced rotation speed of the crusher pulley 1 in turn reduces the movement of several centrifugal devices inside the hollow space 2, in which the mounting shaft 41 and the turning rod 42 and the counterweight balls 43 slowly stop following the rotation of the crusher pulley 1. During the slow stop of the centrifugal device, the centrifugal force generated by the weight ball 43 in the centrifugal device is reduced, and when the centrifugal force generated by the weight ball 43 cannot overcome the acting force of the torsion spring 45, the rotating rod 42 and the weight ball 43 generate a force far away from the crusher pulley 1, so that the extrusion surface 44 is far away from the wear-resistant bushing 31; when the rotation speed of the crusher pulley 1 stops, the extrusion surface 44 is separated from the wear-resistant bushing 31, at this time, the extrusion surface 44 can not drive the wear-resistant bushing 31 to drive the rotation shaft 3 to rotate, the rotation shaft 3 can not drive the fan driving pulley 5 to rotate any more, and the fan driving pulley 5 can not drive the belt between the fan driving pulley 5 and the fan to move, so that the fan is driven to stop working.
