Description

A kind of mixing cutter cutterhead
Technical field
The present invention relates to a kind of mixing cutter cutterhead, be applicable to the catalase of colliery dirt band layer, craven fault, belong to cutter cutterhead technical field.
Background technology
Along with the large scale mining of coal in China, in thick easy mining coal seam constantly reduce, in order to extend the coal mining time further and make full use of coal resources, bring into schedule in coal seam containing the difficulty exploitation such as dirt band and craven fault coal seam, and the tax storage of these coal seams in some mines accounts for 20% of its coal gross reserves, therefore exploit this kind of coal seam to raising coal utilizaton rate, realize sustainable development for mine tool and be of great significance.
At present, the installed power of coal-winning machine can reach the requirement of crushing hard dirt band layer, craven fault, but due to existing coal-winning machine spiral cutterhead being welded with helical blade, the cutter used is pick-shaped cutter, knife shape cutter teeth or dise knife, therefore when cut ragstone, because hauling speed is little, helical blade does not have too large shipment effect, and the breaking capacity of these cutters to ragstone is limited, only can broken f<6 rock and loss is serious.
Summary of the invention
The object of the invention is to overcome the shortcoming that existing coal-winning machine cutterhead rock breaking capacity is strong, cutter consumption is serious, a kind of rational in infrastructure, mixing cutter cutterhead that rock breaking capacity is strong is provided.
The present invention for achieving the above object, is achieved through the following technical solutions: the present invention includes cylindrical tube hub, is arranged on tin pick-shaped cutter of hub periphery and a hob device, and is arranged on the square adapter sleeve in a hub; On cylinder hub top, along the circumferential direction replace the pick-shaped cutter of layout three kinds of angles; In cylinder hub middle and lower part, along only arranging pick-shaped cutter or hob device with bar helix, and along the circumferential direction alternately arrange pick-shaped cutter and hob device, and each hob device is arranged between two pick-shaped cutter transversals; Hobboing cutter cutting diameter is greater than pick-shaped cutter cutting diameter.
Compared with prior art, the present invention adopts on-bladed cutterhead, by the mode of mixing cutter, mainly make use of the extremely strong attrition crushing ability of hobboing cutter and the cutting capacity of pick-shaped cutter, be applicable to the catalase of hard dirt band layer, craven fault in coal seam, the hardness of fractured rock can bring up to f<7 from f<6, the waste of cutter reduces 5%.Simple and compact for structure, fitting operation is convenient, and rock breaking capacity is strong, has practicality widely.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the present invention includes cylindrical tube hub 1, be arranged on pick-shaped cutter 2 and the hob device 3 of a hub 1 periphery, and be arranged on the square adapter sleeve 4 in a hub 1.As shown in Figure 2, on cylinder hub 1 top, along the circumferential direction replace the pick-shaped cutter 2 of layout three kinds of angles; In cylinder hub 1 middle and lower part, along only arranging pick-shaped cutter 2 or hob device 3 with bar helix, and along the circumferential direction alternately arrange pick-shaped cutter 2 and hob device 3, and each hob device 3 is arranged between two pick-shaped cutter 2 transversals.Hobboing cutter 3-1 cutting diameter is greater than pick-shaped cutter 2 cutting diameter.
As a further improvement on the present invention, as shown in Figure 3 and Figure 4, hob device 3 comprises hobbing cutter support 3-2, hobboing cutter 3-1 and skewback 3-4.Hobbing cutter support 3-2 entirety is U-shaped, and trapezoidal hole is offered in side.Hobboing cutter 3-1 comprises the fixed axis 3-1-2 be arranged in trapezoidal hole, is arranged on the taper roll bearing 3-1-3 on fixed axis 3-1-2, the cutterhead 3-1-1 being enclosed within taper roll bearing 3-1-3 outer ring and the end cap 3-1-4 be arranged on outside cutterhead 3-1-1.Skewback 3-4 is fixed on hobbing cutter support 3-2 end face by bolt 3-5, packing ring 3-3, nut 3-6 and is pressed fixed axis 3-1-2.Fixed axis 3-1-2 is pressed in the trapezoidal hole on hobbing cutter support 3-2 top by skewback 3-4, and the size of skewback 3-4 thrust regulates by nut 3-6.
Improve as of the present invention another, as shown in Figure 4, hobboing cutter 3-1 also comprises and is arranged on retainer plate 3-1-7 between cutterhead 3-1-1 and end cap 3-1-4 and cushion cover 3-1-6 by bolt 3-1-5.Retainer plate 3-1-7 offers screwed hole, and is positioned at cushion cover 3-1-6 side by check ring 3-1-10 and interstage sleeve 3-1-9.Offer seal groove in cushion cover 3-1-6, in seal groove, sealing ring 3-1-8 is installed, to realize movable sealing.
During work, cylinder hub 1 is by square adapter sleeve 4 driven rotary, the pick-shaped cutter 2 that the pick-shaped cutter 2 of three kinds of different angles that cylinder hub 1 head is along the circumferential direction arranged is arranged along helix with bottom rotates with cylinder hub 1, while hobboing cutter 3-1 rotates with cylinder hub 1, self also rotates around fixed axis 3-1-2, and reduce the wearing and tearing of hobboing cutter 3-1, the cutting diameter of hobboing cutter 3-1 is greater than pick-shaped cutter 2 cutting diameter, first with hobboing cutter 3-1 fluting during coal petrography cutting, then pick-shaped cutter 2 expands cut groove.Cutterhead does not have helical blade, and the hard mainly utilizing the cutting capacity of the extremely strong attrition crushing ability of hobboing cutter 3-1 and pick-shaped cutter 2 to come to exist in broken coal seam adds cash layer, can the dirt band layer of fractured rock hardness f<7.Cutterhead is simple and compact for structure, fitting operation is convenient, rock breaking capacity is strong.
