The connecting plate 20 is connected to the feeding device, the base plate 22 is fixed to the main body 1, the two ends of the movable telescopic rod 21 are respectively connected to the connecting plate 20 and the base plate 22, the bearing seat 26 is fixed to the base plate 22, the vibrating shaft 27 is connected to the bearing seat 26, one side of the vibrating shaft 27 is connected to the first drive mechanism 18, the first drive mechanism 18 is connected to the main body, the cam 25 is fixed to the middle of the vibrating shaft 27, the mounting base 28 is fixed to the connecting plate 20, and the contact wheel 29 is connected to the mounting base 28, contacting the cam 25. The main body 1 is also equipped with a power distribution cabinet 9, which is used to supply power to various electrical devices to ensure the safety of the device.

[0029] The auxiliary feeding device 15 is used to generate vibration for auxiliary feeding. Specifically, in actual use, the first drive mechanism 18 drives the vibrating shaft 27 to rotate, and the vibration rotation drives the cam 25 in the middle to rotate. During the rotation of the cam 25, it intermittently pushes the contact wheel 29 and generates vibration. The contact wheel 29 transmits the vibration to the feeding device through the mounting base 28 and the connecting plate 20, thereby effectively preventing the crushed slag material from adhering to the feeding device and reducing the risk of the crusher being blocked. It should also be noted that the bearing seat 26 is used to ensure the smooth rotation of the vibrating shaft 27. The first drive mechanism 18 can be a motor or other device. The contact wheel 29 is rotatably connected to the mounting base 28 to ensure that the contact wheel 29 can rotate. During the process of the cam 25 pushing the contact wheel 29, friction is generated between the cam 25 and the contact wheel 29. The rotating contact wheel 29 can convert some of the sliding friction into rolling friction, thereby ensuring the normal rotation of the vibrating shaft 27 and also ensuring the service life of the cam 25 and the contact wheel 29.
