[0006] Furthermore, a rubber expansion tube is fixedly installed between the two groups of mounting seats, and the rubber expansion tube is located outside the corrugated tube.

[0007] Furthermore, the mounting seat is provided with a plurality of groups of mounting holes, and the mounting holes are used for mounting the bellows expansion joint.

[0008] Furthermore, the guide assembly includes a mounting block, and the mounting block is fixedly mounted in several groups on the outside of the mounting seat. A guide column is fixedly mounted on the mounting block at the lower end, and the upper end of the guide column is movably mounted on the mounting block at the upper end.

[0009] Furthermore, a first limiting plate is fixedly mounted on the upper end of the guide column, a second limiting plate is arranged on the lower side of the first limiting plate, and the second limiting plate is fixedly mounted on the guide column.

[0010] The beneficial effects of the utility model are:

[0011] 1. The wear-resistant liner that can be removably installed on the inside of the casing prevents the casing from directly contacting the ore, thereby increasing the service life of the casing. The wear-resistant liner is installed by means of hexagon socket bolts, so when a certain wear-resistant liner is damaged, it can be replaced separately, which is convenient to operate.

[0012] 2 The bellows is protected by a rubber expansion tube arranged outside the bellows, which can prevent the bellows from being damaged by corrosion.

[0013] 3 When the bellows expansion joint is working, the two sets of mounting seats produce relative displacement. The first limit plate and the second limit plate can prevent the two sets of mounting seats from excessive displacement, which plays a certain protective role on the bellows expansion joint.
