Abstract

The utility model discloses an arc-shaped abrasion-resistant three-head spiral body comprising a spiral main shaft, an A-typed spiral blade, a B-typed spiral blade, a C-typed spiral blade, an abrasion-resistant overlaying layer, and arc-shaped patterns. The spiral main shaft is connected with the A-typed spiral blade, the B-typed spiral blade and the C-typed spiral blade. The blades are fixed on the spiral main shaft towards the left and the right in opposite revolving directions based on radial centers in a full penetrating welding mode. The spiral blades are in butt joint at the radial base points to form a sharp-nozzle shape and to be combined into a spiral group. Outer edges of the spiral blades are inwards provided with abrasion-resistant layers along the radial direction within ranges of 180mm in an overlaying mode, the arc-shaped patterns containing hard points are overlaid on the overlaying layer, and a uniform and equidistant three-head structure is formed at fixed intervals. The spiral body has the advantages of being simple in structure, abrasion-resistant, durable, low in price, quick in material discharge, practical, safe, reliable and the like.

Description

Wear-resisting three conveyor screws of arc

Technical field

The utility model relates to wear-resisting three conveyor screws of arc, is particularly useful for the spirochetal helicallobe of the spiral car unloader of thermal powerplant fuel system.

Background technology

The thermal powerplant fuel delivery system contains the raw coal with the outside supply, is mechanically unloaded to the storage location aboard by transportation device, is carrying out next step concentrated conveying.Mechanical type in this process equipment that uses of unloading coal is multiple, comprises spiral car unloader, pick formula car unloader, chain bucket unloader, tipper etc., and spiral car unloader is normally used equipment.

This equipment belongs to a kind of efficient mechanization equipment of unloading coal, and raw coal can be unloaded rapidly from railway truck.The groundwork principle is that helicallobe is released materials in carriage rapidly to both sides by spirochetal rotation, reaches raw coal by the compartment removal.The process of unloading coal is mainly by the rotation of the helicallobe on conveyor screw, the direction of coal along flight to be unloaded the coal back-out.Because often there is the helicallobe serious wear in field working conditions, particularly the helicallobe driving surface at two ends is not durable, its principal element is because helicallobe two ends are groundwork district face, what material was not wear-resisting and thin grade helicallobe causes, this just causes the damage due to helicallobe to cause equipment normally to move, and then affects the standby coal of coal storage.

Summary of the invention
