AI Technical Summary
The chute liners in existing conveyor belt rock discharge systems have short service lives and require frequent replacement, resulting in low operating rates and high costs.
The liner structure, which combines a base plate, rubber inserts, and spacers, is fixed to the inner wall of the feed chute with bolts. The material first accumulates in the spacers, reducing direct wear, extending service life, and allowing for refurbishment by replacing the rubber inserts.
It extends the service life of the feed chute liner, improves reliability and ease of replacement, and reduces replacement frequency and cost.

Abstract
Description
Technical Field
[0001] This utility model relates to a liner plate for a conveyor belt rock discharge chute, belonging to the technical field of conveyor belt rock discharge systems in the metallurgical industry. Background Technology
[0002] Belt conveyor systems primarily use belt conveyors to transport waste rock and other materials, discharging them to designated locations. The feed chute is a crucial component of this system, with a longitudinal section that is an isosceles trapezoid, wider at the top and narrower at the bottom. It plays a key role in guiding material flow and preventing leakage. The feed chute liner's main function is to protect the chute from direct impact and friction from the materials. Commonly used liner materials are manganese steel, with an average service life of only two months, requiring frequent liner replacements and reducing overall operational efficiency. While bimetallic liners can extend service life, they are prohibitively expensive. Utility Model Content
[0003] The purpose of this utility model is to provide a liner for a conveyor belt rock discharge chute, which has a long service life, high reliability, convenient replacement, and reusability, thus solving the problems existing in the background art.
[0004] The technical solution of this utility model is:
[0005] A liner for a conveyor belt rock discharge channel includes a base plate, rubber inserts and spacers. Several parallel spacers are fixed on the base plate, and a spacer groove is formed between two adjacent spacers. Each spacer groove is provided with a rubber insert.
[0006] The rubber inserts in the spacer grooves are fixed to the substrate.
[0007] The spacer plate is arranged perpendicularly to the substrate.
[0008] The substrate, rubber insert, and spacer are combined to form a liner, which is fixed to the inner wall of the feed chute by bolts.
[0009] The base plate of the liner is provided with fixing bolt holes that cooperate with bolts.
[0010] When using this utility model, the liner is fixed to the inner wall of the guide trough with bolts. The material conveyed from the conveyor belt first accumulates and remains in the interval trough. Subsequent material impacts will directly rub against the material accumulated in the interval trough, no longer directly wearing down the guide trough liner, thereby extending the service life of the guide trough liner.
[0011] The advantages of this utility model are: long service life, high reliability, convenient replacement, and reusability. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and examples.
[0018] See attached document Figure 1-4 A liner for a conveyor belt rock discharge channel includes a base plate 1, rubber inserts 2 and spacers 3. Several parallel spacers 3 are fixed on the base plate 1. An interval groove 5 is formed between two adjacent spacers 3. Each interval groove 5 is provided with a rubber insert 2.
[0019] In this embodiment, refer to the appendix Figure 1-3 The liner includes a base plate 1, a rubber insert 2, a spacer plate 3, fixing bolt holes 4, and a spacer groove 5, wherein:
[0020] The substrate 1 is made of low-cost manganese steel, with a length, width and thickness of 600*300*40mm. The rubber insert 2 is made of rubber, with a length, width and thickness of 600*300*20mm. The spacer 3 is made of manganese steel, with a length, width and thickness of 300*20*60mm. The spacing between the spacers 3 is 80mm. Several spacers 3 are welded to the substrate 1 respectively, and a spacer groove 5 is formed between two adjacent spacers 3.
[0021] See attached document Figure 4 When in use, the liner is fixed to the inner wall of the guide trough 6 by bolts through the fixing bolt holes 4. The material 8 conveyed from the conveyor belt 7 first accumulates and remains in the interval trough 5. Subsequent material impacts will directly rub against the material accumulated in the interval trough 5, no longer directly wearing down the guide trough liner, thereby extending the service life of the guide trough liner.
[0022] Through use, it was found that the average service life of the partition plate 3 is up to 6 months, and the average service life of the rubber insert 2 is up to 5 months. When the rubber insert 2 reaches the end of its service life, the entire feed chute liner can be replaced directly. The disassembled old feed chute liner can be refurbished by replacing the rubber insert 2 and the partition plate 3, and reused. Therefore, considering cost consumption, service life, and replacement frequency, this feed chute liner is superior to other liners.
