primary cause birth mechanism was the need for irrigation farmers in ancient Egypt, Mesopotamia, China, India.We know that farmers in these countries have long had to artificially irrigate their crops.And then I found a method using primitive tools to adjust the transportation of water.They were called in different countries in different ways, but the principle had shared.Later, with the invention of the wheel, people have learned to use the power of water for the job.
In the time of ancient Greece and the Roman Empire mills, aqueducts, other mechanisms were set in motion with the help of slaves, and later - with the help of animals.
Stages improving
But proper conveyor belts, familiar and intended for industrial use, only appeared in the 18th century.First, they served as the basis for the board, on which the tape is moved from leather or canvas.In 1908, the Heimlich Goddard patented roller basis for conveyors.But the real "parent" conveyor belt-conveyor became Henry Ford, who noted that workers lose too much time in the delivery of spare parts to the workplace, and set conveyor belt on which parts move from one shop to another.This has contributed to increased productivity, reduced production costs and was the starting point in the development pipelines.
Eventually moving mechanisms became more perfect.A new round of belt conveyors gained with the development of the industrial development of different deposits (gold mining, coal, ores).
Types and scope
Today variety of striking transporters.With them we get things in the airport operate bakery, confectionery, printed papers, collect cars, pick up coal from the mines and move huge distances rock from quarries.
Application pipelines saves time, optimizes the production process and get rid of the heavy manual labor.
His device, compared with the other lifting devices, it is quite simple, it is easy to repair and operation.The main components of the conveyor is:
- support (stationary or adapted for movement);
- drive belt conveyor, which consists of an electric motor, gear (cylindrical screw with a chain or belt transmission or belt-gear type) and the drive pulley;
- supporting surface (rollers or sheet metal);
- carrying the body - the conveyor belt;
- tension mechanism (drum and screw).
to move various materials invented several types of conveyor belts:
- tape;
- plate;
- inertia;
- vibration;
- roller;
- scraper;
- load-carrying;
- pushing;
- Wagon;
- and bucket of cradle;
- screw.
Some of them have a special meaning, for example, to carry passengers (escalators).The direction of movement of goods can be anything - horizontal, inclined, vertical.
Indeed, the conveyor belt has the status of the most popular mechanism to move virtually any material.Modern electronics and automation to increase its capacity many times over.
