Description

Grain drying-machine is slow soviet layer pull rod mechanism

Technical Field

The utility model belongs to the technical field of grain cereal is dried, more specifically, relate to a grain drying-machine is slow su layer pull rod mechanism.

Background

The grain drying mechanization technology is a drying technology which takes machinery as a main means, adopts corresponding processes and technical measures, artificially controls factors such as temperature, humidity and the like, and reduces the water content in grains on the premise of not damaging the quality of the grains so as to enable the grains to reach the national safe storage standard. The grain drying mechanization technology changes the tradition that grain drying is simply dependent on natural sunlight to be tedded on a sunning ground for a long time, and advances a step towards comprehensively realizing agricultural mechanization and modernization.

The grain dryer is widely applied to drying grain, and has the characteristics of simple structure, high drying efficiency, good drying quality and the like; grain drying-machine adopts tower box structural design mostly, and cereal flows from top to bottom, vertically passes the drying chamber, combines together at drying chamber and dry hot-blast to reach the dry effect of hydrofuge. The drying process needs a tempering stage, particularly the drying of the paddy, needs a certain tempering time, and the length of the tempering time determines the design size of a tempering bin; the tempering storehouse is located the upper portion of drying chamber, is connected the box that forms by multilayer bounding wall and inside pull rod and constitutes, and tempering storehouse height is higher more, and the cereal weight that bears just is big more, and tempering storehouse bounding wall and pull rod bear pressure just also big more simultaneously, and firm tempering storehouse structural design is the prerequisite of guaranteeing drying-machine safety drying.

The traditional tempering bin structure is formed by fixedly connecting a plurality of layers of coamings through staggered section bar pull rods, the pull rod structure is designed to be used for common sections such as round pipes, square pipes or oval pipes, the sections are fixedly installed in a mode of connecting a fixing plate in a matched welding mode, the structure is designed to be used for drying machines with middle and small tonnage, and the tempering bin structure has the advantages of being low in processing cost, convenient to install and the like. The loading capacity of a tempering bin of the dryer with a larger tonnage is larger, the structural design can not meet the requirement of bearing capacity, and the risks of bending of a pull rod or deformation of a coaming and the like are easily caused; if use the section bar fixed connection of great model, the pull rod structure dead weight is obvious, and design cost is high, and the installation is inconvenient, and transversely area occupied is great, hinders the flow of cereal stoving process, influences the cereal drying degree of consistency.

Through the retrieval, the name that utility model created is: a stay bar (application number: 201720654358.5') used in the interior of the grain dryer box body. The application discloses a design method of a pull rod structure in a tempering bin of a dryer, wherein the pull rod structure mainly comprises a plurality of layers of surrounding plates which are fixedly connected through staggered section pull rods, the pull rod structure is designed to be a multipurpose common section such as a round pipe, a square pipe or an oval pipe, and the multipurpose common section is fixedly installed in a mode of being matched and welded with a fixing plate. This structural design has certain limitation, and the bearing capacity is limited, is not suitable for the drying-machine of large-tonnage, and this structure is when meetting the cereal of high humid water content, easily produces the bridging phenomenon, piles up cereal and makes local pull rod atress increase, and the bounding wall warp the bending, has the potential safety hazard.
