Abstract
The utility model discloses a cannon head center cutter, which belongs to the field of cutters for a coal mining machine and relates to a damageable part of the coal mining machine. The cannon head center cutter mainly comprises a cutter body which is provided with a soldered hard alloy blocks and is characterized in that: symmetrical hard alloy blocks are soldered on the cutter body; and a wearing layer is overlaid on the surface of the cutter body, so that the cutting function of the cannon head center cutter is enhanced, the wearing performance is more durable and the service life is prolonged greatly.
Description
Technical field
The utility model belongs to coal digger cutter field, particularly a kind of improved coal digging machine gun head center cutter.
Background technology
Big gun head center cutter is a coal digger cutter, belongs to coal digger rapid wear accessory, is installed on the tool rest of coal digging machine gun head center, with the common operation of pick tooth, finishes excavation, the tunneling construction of coal.Present big gun head center cutter steel manufacturing has heat treatment hardness, but because of the soldering hard alloy blocks is not installed, does not have the build-up wear-resistant layer, and the function of its cutting coal seam, gangue can not satisfy instructions for use, and not wear-resistant, application life is short.
The innovation and creation content
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and novelty is wear-resistant, and it is extensive to adapt to coal seam conditions, and cutting coal seam, gangue function are strong, the big gun head center cutter of long service life.
Above-mentioned superiority is to realize like this
Respectively offer a symmetrical open type groove in cutter hub top and arranged on left and right sides, be used for installing the soldering hard alloy blocks; The symmetrical soldering of hard alloy blocks difference is on the open type groove on the cutter hub; And at the thicker wearing layer of cutter hub surface overlaying, make big gun head center cutter cutting coal seam, the increased functionality of cutting gangue, abrasion resistance properties is superior, and improve application life.
Description of drawings
Figure of description is a schematic diagram of the present utility model.Fig. 1 is a front view, and Fig. 2 is a vertical view, and Fig. 3 is that K is to view.Among the figure 1 is cutter hub, the 2nd, and hard alloy blocks, the 3rd, wearing layer, 4 is two open-works.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
In the bottom of cutter hub 1 two through hole 4 is arranged, big gun head center cutter is installed on the tool rest by two through hole 4 usefulness bolts.
And arranged on left and right sides on the top of cutter hub 1 is respectively offered a symmetrical open type groove, is used for installing soldering hard alloy blocks 2 respectively; The symmetrical soldering of hard alloy blocks 2 difference is on two open type grooves of cutter hub 1; At two skewed surfaces of cutter hub 1 and near the thicker wearing layer 3 of built-up welding on the back of hard alloy blocks 2.Through after the above-mentioned improvement, big gun head center cutter cutting coal seam, the increased functionality of cutting gangue, abrasion resistance properties is superior, and increase application life.
Claims (2)
1. big gun head center cutter mainly comprises the cutter hub (1) except that hard alloy blocks (2), wearing layer (3), it is characterized by: respectively offer a symmetrical open type groove in the and arranged on left and right sides of cutter hub (1), in order to soldering hard alloy blocks (2) to be installed.
2. big gun head center cutter according to claim 1 is characterized in that: build-up wear-resistant layer (3) on two skewed surfaces of cutter hub (1).
