Abstract
The utility model discloses a wearable structure of a drum rotary vane plate and an arc-shaped coal baffle plate for a coal mining machine. The wearable structure comprises structural layers in a herringbone shape, a square lattice shape, a skew lattice shape, a strip shape and a wave shape, which are arranged on the drum rotary vane plate and the arc-shaped coal baffle plate in a build-up welding way by using wearable welding rods, and wearable alloy blocks are arranged at intervals in the build-up welding way above the drum rotary vane plate and the arc-shaped coal baffle plate, on which the structural layers in the herringbone shape, the square lattice shape, the skew lattice shape, the strip shape and the wave shape are arranged in the build-up welding way. On the basis that the materials and the manufacturing processes of an original rotary vane plate and the arc-shaped coal baffle plate are not changed, wearable alloy layers in different shapes are arranged on the drum rotary vane plate and the arc-shaped coal baffle plate of the coal mining machine in the build-up welding way; the wearability of the drum rotary vane plate and the arc-shaped coal baffle plate is effectively improved; the wear of coal and a coal gangue to a drum rotary vane and the arc-shaped coal baffle plate is decreased; the service life is improved; and the wearable structure is simple in structure, low in cost and good in wearable effect.
Description
Technical field
The utility model relates to a kind of abrasion-proof structure, especially a kind of abrasion-proof structure that is applicable to coal mining machine roller vane plate and arc spillplate.
Background technology
Cylinder is the important process mechanism that the coal-winning machine coal cutting is coaling, and mechanical coal mining can alleviate manual labor, improve safety, reaches high yield, high efficiency, low consumed purpose.Flitting is suitable for using under the condition simple at little, the no horsestone of Coal Seam Thickness Change, geological structure, that top board is easy to manage.When the inclination angle is big, need the dress shoe.Flitting rides on the flexible flightconveyor and works, and comes and goes operation along work plane.The pick of arranging according to certain rules is housed on the spiral cylinder.When cylinder rotated, pick successively cut a lot of grooves in certain sequence on coal body, the coal body between the groove is declined, through cylinder vane plate and the arc spillplate conveyer of packing into.Diameter of cylinder is selected according to mining height, has 1.6,1.8, a plurality of specifications such as 2.0m.
Because coal-winning machine is that running environment is comparatively abominable, and is stressed bigger with the broken coal of rotary work mechanism, cylinder vane plate and the wear-resisting inefficacy of arc spillplate appear in regular meeting, will cause coal-winning machine to shut down maintenance, influence coal production.Along with the modernization of coal production technology, digging equipment, coal mining intensity constantly increases, and the abrasion resistance of cylinder vane plate and arc spillplate is had higher requirement.
Summary of the invention
The purpose of the utility model is to overcome weak point in the prior art, and a kind of simple in structure, cheap, effective coal mining machine roller vane plate and arc spillplate abrasion-proof structure are provided.
For realizing above-mentioned purpose; Coal mining machine roller vane plate of the utility model and arc spillplate abrasion-proof structure; Comprise herringbone with wear resistance electrode built-up welding on cylinder vane plate and arc spillplate, criss-cross, tiltedly lattice shape, strip, wavy shaped configuration layer, built-up welding have herringbone, criss-cross, tiltedly on cylinder vane plate and the arc spillplate of lattice shape, strip, wavy shaped configuration layer at interval built-up welding wear-resisting alloy block is arranged.
Described wear-resisting alloy block is square, bar shaped or circle.
Beneficial effect: the utility model is on the basis that does not change former vane plate and arc spillplate material and manufacturing process; Be employed in the wear-resistant alloy layer of built-up welding definite shape, size, size on coal mining machine roller vane plate and the arc spillplate; Effectively improved the abrasion resistance of cylinder vane plate and arc spillplate; Reduced the wearing and tearing of coal and gangue to cylinder vane and arc spillplate, thus the application life of improving coal mining machine roller vane plate and arc spillplate effectively, and it is simple in structure, cost is low; Wear-resisting effective, have practicality widely.
