Overview
​​
Chain conveyor is a general term for continuous conveyors with chains as flexible traction members. It includes buried scraper conveyors (such as 0939), scraper conveyors (such as 2333), zipper conveyors (such as 2705) and skirt conveyors (such as 0705, 0706), etc. Compared with other conveying machinery, this The type conveyor has the characteristics of simple structure, convenient operation, easy manufacture and maintenance, etc., so it is widely used in construction materials, metallurgy, grain processing and other industries.

Chain Features
​​
Chain conveyors all use chains as traction members. Compared with other flexible traction members, the advantages of chains are that they can bypass small diameter sprockets and pulleys, especially when using short pitch chains, it is easy to fasten on the chain. Connect working components
​​
Second, take the zipper conveyor as an example to briefly introduce the structure and common faults
​​
The currently used zipper conveyors mainly include 2705(1)(2), 2706(1)(2), 2715, 2716, 0528, 2528 grate cooler zipper machines, etc.

1. Working principle, performance and application
​​
The zipper machine is a transportation equipment that continuously transports materials by means of the movement of the chain in the closed machine groove. When the zipper machine is working, the material flows into the machine groove continuously through the feeding chute. Internal friction force is generated. Because the speed of the chain is very small (0.31m/s), the balance and stable state between the material layers are ensured, and there is no significant relative movement between the materials. Only near the two side walls of the machine slot, the material particles are There is some hysteresis, so this balance and stable state between the materials constitutes a continuous flow of materials to achieve the purpose of being transported, and the materials are discharged from the discharge port of the zipper machine. Its characteristics are: simple equipment structure, convenient installation and maintenance, flexible process selection and layout, multi-point feeding, multi-hanging point unloading, closed transportation of materials in the shell, reduced dust, and improved working environment. At present, the zipper machine is mainly used for clinker conveying.

2. Introduction to the structure:
​​
The zipper machine is mainly composed of the head transmission device, the casing, the traction chain, the idler device, the tail and the tensioning device, and the alarm device. The drive of the zipper machine is completed by the transmission device (such as 2705). The motor starts and transmits the power to the main shaft equipped with the sprocket through the reducer. Driven by the sprocket, the traction chain moves slowly, and the material is conveyed from the tail to the head. , discharged from the discharge port. The teeth and the hub of the zipper head sprocket are manufactured separately and connected together by bolts. After the teeth are worn, they can be replaced. The traction chain is an important part of the zipper machine. It bypasses the head sprocket and the tail wheel to form a closed loop. The upper branch does not convey materials, and the lower branch conveys materials. The upper branch chain is supported by the idler device, and the chain is composed of many links Connected by a chain shaft.
