The coal industry is an important basic industries，China's coal production is the first in the world, coal producing countries，however, coal mining technology and equipment of our overall low level of，coal production is mechanized equipment, part of both mechanized and manual operation of the multi-level structure. Low level of technology and equipment, seriously affect the efficiency of coal production.To protect the supply of coal is the coal industry to strengthen macro-control of one of the key points，deep processing of coal is the most important national industrial development,coal mine production equipment is the one of the main equipment for coal equipment reliability, Special location is the key to the throat of coal equipment reliability, a direct impact on the entire production system to normal operation. Practice has proved that the existing reciprocating Feeder small production, With the development of coal industry and coal-wells continues to expand, the existing K-type reciprocating coal production capacity of the small plane, unable to meet the requirements of large-scale mine, therefore, improve and expand existing K-type reciprocating to the coal machine is totally necessary. The design of the reciprocating to the coal on the basis of the original made some improvements, it has a simple structure and a small amount of maintenance, stable performance, low noise, the installation is easy.This paper introduced：Reciprocating coal conveyor history of the development, use, composition and physics; Reciprocating to the characteristics of coal; focusing on reducer, transmission platform, crank linkage, strength check, in accordance with its common failure mode, Factors and basic design requirements, is an important component of the stress analysis, strength and stiffness of the design method.
