What are the classifications and future development of conveyors

The emergence of conveyors has laid the foundation for assembly line operations, which can greatly save labor costs and improve production efficiency.

Common conveyors are classified as rollers, belts, chain plates, mesh belts, and the third-grade components of Husou with traction ability Including traction parts, bearing members, driving devices, tensioning devices, redirecting devices and supporting parts, etc. The traction part is used to transmit the traction force, which can be a conveyor belt, a traction chain or a steel wire rope; the bearing member is used to hold the material, such as a hopper, a bracket or a spreader, etc. It is composed of a brake (stopper), etc.; the tensioning device generally has two types: screw type and heavy hammer type, which can keep the traction member in a certain tension and sag to ensure the normal operation of the conveyor; the supporting member is used to support the traction member. Or bearing members, rollers, rollers, etc. can be used.

The structural feature of a conveyor with a tractor is that the conveyed material is loaded in the bearing member connected with the tractor, or directly mounted on the tractor. On a conveyor belt (such as a loading conveyor belt), the traction members are connected end to end around each roller or sprocket, forming a closed loop including a loaded branch that transports materials and an unloaded branch that does not transport materials, and uses the continuous movement of the traction members to transport materials.

There are many kinds of such conveyors, mainly belt conveyors, slat conveyors, trolley conveyors, escalators, moving walks, scraper conveyors, buried conveyors, etc. Scraper conveyors, bucket conveyors, bucket elevators, hanging conveyors and platoon ropeways, etc.

The structure and composition of conveyors without traction parts are different, and the working components used to convey materials are also different. Their structural features are: using the rotary motion or reciprocating motion of the working member, or using the activity of the medium in the pipeline to transport the material forward. For example, the working component of the roller conveyor is a series of rollers, and the rollers rotate to transport the material; the working component of the screw loading conveyor is a screw, and the screw rotates in the trough to push the material along the trough; the work of the vibrating conveyor The component is a trough, and the trough reciprocates to transport the materials placed in it.

In the future, the conveyors will develop towards large-scale development, expanding the scope of use, automatic sorting of materials, reducing energy consumption, and reducing pollution.

Large-scale includes several aspects such as large conveying capacity, large single machine length and large conveying inclination. The length of the hydraulic conveying device has reached more than 440 kilometers, and the single length of the belt conveyor has reached nearly 15 kilometers, and several 'belt conveyors' have appeared to connect the two places. Many countries are exploring a more complete conveyor structure for continuously conveying materials with long intervals and large volumes. Expanding the scope of use of conveyors refers to the development of conveyors that can work in environments with corrosive, radioactive, and flammable substances under the premise of high temperature and low temperature, and can transport hot, explosive, agglomerate, and viscous materials. .

The future development trend of conveyors is:

①Inherit to large-scale development. Large-scale includes several aspects such as large conveying capacity, large single machine length and large conveying inclination. The length of the hydraulic conveying device has reached
440km+. The single-machine length of the belt conveyor is nearly 15 kilometers, and several 'belt conveyors' have appeared to connect the two places. Many countries are exploring a more complete conveyor structure for continuously conveying materials with long intervals and large volumes.

②Expand the scope of use of the conveyor. Develop conveyors that can work in environments with corrosive, radioactive, and flammable substances under the premise of high temperature and low temperature, and can transport hot, explosive, agglomerated, and viscous materials. ③ Make the structure of the conveyor meet the requirements of the automatic control of the material handling system for a single machine. For example, the trolley conveyor for automatic sorting of parcels used by the post office should be able to meet the requirements of sorting operations.

④Reducing energy consumption to save energy has become an important aspect of scientific research in the field of transportation technology. The energy consumed by 1 ton of material conveying 1 km has been taken as one of the important indicators for conveyor selection.

⑤Reduce dust, noise and exhaust gas generated by various conveyors when they do their homework.
