As shown in fig. 2, the driving ring 21 includes a fixing ring 211 sleeved and fixed on the outer surface of the trommel 1 and wedge blocks 212 fixed on the outer ring surface of the fixing ring 211, the number of the wedge blocks 212 is not particularly limited, and four wedge blocks 212 in the embodiment are provided; according to the arrangement of the wedge blocks 212 in fig. 2, the rotation direction of the trommel 1 in the present embodiment is defined to be counterclockwise, and when the trommel 1 rotates, the fixing ring 211 and the wedge blocks 212 both rotate together with the trommel 1.
As shown in fig. 2, the elastic impact member 22 includes a spring expansion rod 221 radially disposed along the trommel 1, wherein an expansion shaft of the spring expansion rod 221 abuts against an outer circumferential surface of the fixed ring 211, the expansion shaft of the spring expansion rod 221 gradually contracts due to an inclined surface of the wedge block 212 during rotation of the fixed ring 211, after the expansion shaft of the spring expansion rod 221 slides over the wedge block 212, the expansion shaft of the spring expansion rod 221 instantaneously protrudes and impacts on the fixed ring 211 due to loss of support of the wedge block 212, thereby forming vibration, and materials clamped inside the screen holes of the trommel 1 are vibrated off by the vibration, specifically, the spring expansion rod 221 gradually contracts and accumulates elastic potential energy during sliding of the expansion shaft over the inclined surface of the wedge block 212, and then the elastic potential energy accumulated by the spring expansion rod 221 is released after the expansion shaft completely slides over the inclined surface of the wedge block 212, so that the expansion shaft impacts the fixed ring 211 to generate vibration.
For the spring telescopic rod 221, the telescopic shaft and the spring arranged in the telescopic shaft are matched for use, so that the spring telescopic rod 221 can achieve an elastic telescopic effect.
In the above scheme, the wedge block 212 is driven to rotate by the fixing ring 211, so that the inclined surface of the wedge block 212 drives the spring telescopic rod 221 to shorten to generate elastic potential energy, then after the telescopic shaft completely slides across the inclined surface of the wedge block 212, the elastic potential energy accumulated by the spring telescopic rod 221 is released, the telescopic shaft is pushed to quickly strike the fixing ring 211 along the radial direction of the rotary screen 1 to generate vibration, and the vibration is transmitted to the rotary screen 1 to shake down materials clamped inside the screen holes of the rotary screen 1, so that the screen holes of the rotary screen 1 are prevented from being blocked for a long time.
Further, as shown in fig. 3 and fig. 4, the telescopic shaft is fixedly connected with a straight spring 224, the straight spring 224 is arranged along the radial direction of the telescopic shaft, and an impact block 225 is installed at one end of the straight spring 224 away from the telescopic shaft, in the process that the telescopic shaft quickly impacts the fixing ring 211, the impact block 225 also quickly moves towards the drum screen 1 along with the telescopic shaft, after the telescopic shaft contacts the fixing ring 211, the impact block 225 continuously impacts the drum screen 1 under the action of inertia until impacting the surface of the drum screen 1, so that the drum screen 1 vibrates again, when the impact block 225 contacts the drum screen 1, the straight spring 224 is in a bending state, and therefore, after the impact block 225 impacts the drum screen 1, the impact block 225 gradually returns to the initial position under the action of the elasticity of the straight spring 224.
In the above scheme, through setting up with telescopic shaft fixed connection's straight spring 224 to the fixed impact piece 225 of one end that keeps away from the telescopic shaft at straight spring 224, thereby can collide solid fixed ring 211 after the telescopic shaft and make use of impact piece 225 again and collide drum sieve 1 and clash, be favorable to shaking down the material of chucking in drum sieve 1 sieve mesh inside more.
Further, in order to reduce the friction force between the telescopic shaft and the outer ring surface of the fixed ring 211 and the inclined surface of the wedge block 212, as shown in fig. 2 to 4, a roller 222 is rotatably connected to one end of the telescopic shaft, which is close to the fixed ring 211, so as to realize rolling connection between the telescopic shaft and the outer ring surface of the fixed ring 211 and the inclined surface of the wedge block 212, then, in order to reduce the friction force between the roller 222 and the outer ring surface of the fixed ring 211 and the inclined surface of the wedge block 212, a dust removing brush 223 is fixed on the roller 222, in the rotating process of the fixed ring 211, the dust removing brush 223 firstly brushes away the impurity particles on the outer ring surface of the fixed ring 211 and the inclined surface of the wedge block 212, and then the roller 222 is in rolling contact with the outer ring surface of the fixed ring 211 and the inclined surface of the wedge block 212.
