Abstract
The utility model relates to a screw drum for a cutting head of a development machine. Screw blades are fixedly arranged on the outer surface of the screw drum for cutting head of development machine according to the direction of a screw line. The utility model has the advantages of simple structure, reasonable design and easy installation; the external diameter of the screw drum for cutting head of development machine is consistent with the external diameter of the back part of a cutting head, the screw angles of the screw blades are consistent with the arranged screw angles of cutting teeth on the cutting head, so the utility model extends the service life of the cutting head, ensures the material aggregating fluency and simultaneously shortens the distance between the cutting head and a shovel plate.
Description
Technical field
The utility model belongs to mining and uses plant equipment, especially relates to a kind of cutting head of roadheader helix drum.
Background technology
At present, the cutting units of development machine has two kinds: a kind of have a Telescopic, and both (development machine location) can move forward and backward during cutterhead work, and another kind does not have Telescopic.The distance that the development machine that does not have a Telescopic cutterhead and development machine when work gather materials between the shovel board is uncontrollable, and the operation of gathering materials is not smooth.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, and smooth cutting head of roadheader helix drum gathers materials.
In order to achieve the above object, the technical solution adopted in the utility model is: be fixed with helical blade by hand of helix on the cylinder outer surface.
The utility model has the advantages that:
The outside diameter of cylinder of installation simple in structure, reasonable in design, easy, helix drum is consistent with cutterhead rear portion external diameter, the lead angle that pick is arranged on the lead angle of helical blade and the cutterhead is consistent, improved the life-span of cutterhead, guarantee the smoothness of gathering materials, shortened the distance of cutterhead and shovel board simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is cutterhead and cylinder connection diagram;
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 3 as can be known, the utility model is to be fixed with helical blade 2 by hand of helix on cylinder 1 external surface.
The utility model is formed helix drum by cylinder 1, helical blade 2, helical blade 2 is welded on cylinder 1 external surface, helical blade 2 is according to two lift angle unanimities of cutterhead pick, the height of helical blade 2 will be adjusted according to the requirement of development machine, the high abrasion resistance of material requirements of helical blade 2 and cylinder 1.Helix drum is welded on the rear portion of cutterhead 3, reaches the unification of lead angle, will guarantee that simultaneously the cylinder of helix drum and the external diameter of the body of the cutting head are more or less the same, and guarantees the smooth and easy of material.
Cutting head of roadheader 3 diameters and length depend on the cut power of development machine, and its distance apart from shovel board will be considered multiple factor: cut scope, planted agent's amount, the cut arm of force etc.
Claims (1)
1. a cutting head of roadheader helix drum comprises cylinder, pick, it is characterized in that: be fixed with helical blade (2) by hand of helix on cylinder (1) external surface.
