The idler is hung on the pin through the tooth slot and can be moved forward and backward to adjust the position of the idler to control the belt deviation.
(4) feeding device and discharging device:
The feeding device is installed behind the receiving and unloading device, which is connected by a steering guide to the feeding section, from which the transported materials are loaded and transported to the discharging section. The discharging device is unloaded by a set of inclined rollers in the discharging section, and the unloading section is directly extreme. The machine tail is composed of a guide rail and a tail drum seat, one end of the guide rail is fixed on the middle support with bolts, and the front end of the other rail is glued with a pin to adapt to the uneven bottom plate. The structure of the tail drum is the same as that of the drum in the belt storage device, and the position of its axis can be adjusted by bolts to adjust the deviation of the conveyor belt at the tail of the machine. A coal scraper is arranged at the front end of the drum, which can scrape off the crushed coal or pulverized coal on the surface of the drum and collect the mud trough. The tail of the machine is equipped with a cushioning roller group, which can reduce the impact of lump coal on the belt and improve the life of the belt.
The telescopic belt conveyor adds a telescopic mechanism to the ordinary belt conveyor, so that the belt conveyor can stretch freely in the length direction. Users can adjust the button according to their own requirements and control the length of the conveyor at any time. On the model with automatic lifting device, the user can also control the height of the end of the conveyor at any time. Telescopic belt conveyor is mainly used in vehicle loading and unloading and material transmission system with telescopic requirements. It greatly shortens the distance of manual transportation of materials, shortens the loading and unloading time, reduces labor intensity, reduces goods damage, reduces loading and unloading costs, and improves work efficiency. The telescopic belt conveyor can transport materials in both directions. Telescopic belt conveyor can be used in conjunction with other conveying equipment and material sorting system to realize the automatic production of materials in and out of warehouse or vehicle loading and unloading, especially in the tobacco industry.
Detailed analysis of the structure and principle of telescopic belt conveyor
1. The telescopic belt conveyor is mainly composed of the following components: head frame, driving device, transmission drum, tail frame, intermediate frame, tail redirection device, unloading device, cleaning device, tensioning device, belt storage device and so on.
2. The conveyor belt is the bearing component of the belt conveyor, the material on the belt runs together with the conveyor belt, the material runs together according to the conveyor belt, and the material can be unloaded at the end or middle part of the conveyor according to the need. The conveyor belt is supported by rotating rollers, and the running resistance is small. The telescopic belt conveyor can be arranged along the horizontal or inclined line. The conveyor belt is used as the traction load bearing component. A continuous transport equipment for conveying materials through the movement of a conveyor belt that carries materials.
3. The conveyor belt forms an infinite annular belt around the transmission drum and the tail drum, and the upper and lower conveyor belt is supported by rollers to limit the deflection and sag of the conveyor belt, and the tension device provides the necessary tension for the normal operation of the conveyor belt.
4. When working, the driving device drives the transmission drum, drives the conveyor belt through the friction between the transmission drum and the conveyor belt, and the material is installed on the conveyor belt to move together with the belt conveyor.
What are the characteristics of the belt telescopic conveyor?
Belt conveyor is widely used in industrial enterprises because of its simple structure, convenient maintenance and various kinds of conveying materials. So what are the advantages? 1. A wide range of conveying materials can range from very fine powdered materials to large chunks of ore, stone, coal or pulp wood, and fine screened or fragile materials can be transported with a minimum drop. Because the rubber conveyor belt has high corrosion resistance, the maintenance cost is relatively low when conveying strong corrosive or abrasive materials. The belt conveyor can also transport alkaline materials and hot materials at a certain temperature, as well as articles. 2. the conveying capacity of the wide range of conveying capacity of the belt conveyor can meet any required conveying task. there are both light belt conveyors to complete the conveying task with small capacity, and large belt conveyors to achieve the conveying task of thousands of tons or even tens of thousands of tons per hour. 3. The adaptability of the conveying line the belt conveyor can adapt to the terrain with a slope of 30% “35%”, while for truck transportation, it can only adapt to the slope of the original natural area, which is 6% “8%. Conveyor lines can adapt to the terrain, bend in space and horizontal plane to reduce infrastructure investment, and avoid interference from railways, roads, rivers and mountains in factories or other crowded areas. The transport line of the belt conveyor is very flexible, and the length of the line can be extended according to the needs. 4. Flexible loading and unloading belt conveyor can flexibly receive materials from one or more points according to the requirements of the technological process, and can also unload materials to multiple points or several sections. 5. Strong reliability the reliability of belt conveyor has been confirmed by experience in all industrial fields, and its operation is extremely reliable. It has been widely used in many important production units that need continuous operation, such as the transportation of coal in power plants, the transportation of bulk materials in iron and steel plants and cement plants, as well as the loading and unloading of bulk materials in ports. 6. High safety belt conveyor has high safety, needs few production personnel, and has less chance of accidents compared with other modes of transportation. Accidents will not be caused by large chunks of material falling and hurting people or due to the handling failure of large, bulky vehicles. 7. Low-cost belt conveyor system requires man-hours and energy consumption per ton of bulk materials, which is usually the lowest of all means of transporting bulk materials. And it takes less time for maintenance personnel, the maintenance and replacement of smaller parts can be completed quickly on site, and the maintenance cost is low. no, no, no. I hope my answer can help you, and I hope to adopt it.
What are the categories of belt telescopic conveyors?
Belt conveyor is usually used for the transportation of loose materials or finished articles. Generally, it is divided into types and types according to the technology of conveying materials and conveyors. We have sorted out four common types of belt conveyors as follows:

1. Mobile belt conveyor
Mobile belt conveyor is a kind of continuous conveying loading and unloading equipment with high working efficiency, flexible movement and good mobility. The mobile belt conveyor can design the use length and lifting height according to the actual conditions such as the conveying requirements of users, and the general conveying height can reach 1.2-1.8m according to the difference of belt bandwidth and conveying length.
two。 Large inclination angle belt conveyor
Through the free retractable rubber waveform vertical “skirt” glued to both sides of the flat rubber transport belt, and with the help of diaphragms with certain strength and elasticity between the skirt to form a box-shaped bucket, so as to realize the continuous transportation of materials in the bucket, this is the high-angle belt conveyor. In general, high-angle belt conveyor is suitable for dispersed powder, particles and fine paste and liquid materials, such as coal, gravel, limestone, sand, clay, sand sintered powder, sawdust and so on.
3. Climbing belt conveyor
Climbing belt conveyor is a kind of belt conveyor which can lift objects at a large angle by adding strips, metallurgical tools, skirts and other ways on the belt. The climbing type can not only be used for ordinary material transportation, but also can meet the special requirements of oil resistance, anti-corrosion, anti-static and so on.
4. Retractable belt conveyor
As the name implies, the difference between the telescopic belt conveyor and other conveyors is that it can achieve free expansion to control the conveying length of the belt conveyor. Retractable belt conveyor can not only achieve efficient transportation, but also can be used with other conveying equipment, so it is widely used in automatic production. It is suitable for the transportation of materials with high temperature, large weight, large volume and wear, such as ash, cement clinker, iron slag, slag, limestone, coke, macadam and so on.
