FIG. 1 is a schematic illustration of a cutting head and cantilever segment spline connection;
FIG. 2 is a schematic diagram of the structure of the present utility model;
in the figure, 1, a cutting head; 2. a cutting head shaft; 3. a fixing bolt; 4. a steel wire retainer ring; 5. a floating seal seat; 6. a cantilever section; 7. connecting a flat key; 8. a nut; 9. the cutting head is connected with the bolt.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
the connecting mechanism of the cutting head and the cantilever section of the heading machine comprises a cutting head 1, a cutting head shaft 2, a floating sealing seat 5 and a cantilever section 6, wherein the cutting head 1 is arranged at the top end of the cutting head shaft 2, the floating sealing seat 5 is arranged between the cutting head 1 and the cutting head shaft 2, and dust and impurities are prevented from entering between the cutting head 1 and the cutting head shaft 2 in the cutting process, so that abrasion between the cutting head and the cutting head shaft is avoided; the cantilever section 6 and the cutting head shaft 2 are supported by a bearing, and the cutting head shaft 2 can freely rotate in the cantilever section 6; nut 8 cup joints floating seal seat 5 and fixes on cutting head axle 2, through spline connection, cutting head axle 2 and floating seal seat 5 between, and cutting head axle 2 is through connecting the spline with power transmission for floating seal seat 5, and floating seal seat 5 is connected with cutting head 1 through connecting flat key 7, gives cutting head 1 with power transmission, and cutting head 1 and floating seal seat 5 use cutting head connecting bolt 9 to be fixed at the inner chamber internal connection.
When the coal seam cutting device is used, the motor of the heading machine drives the cutting head shaft 2 to rotate in the cantilever section 6, the cutting head shaft 2 drives the floating seal seat 5 to rotate through spline connection, and the floating seal seat 5 rotates to drive the cutting head 1 to rotate through parallel key connection, so that the power output of the heading machine for cutting the coal seam is realized.
While one embodiment of the present utility model has been described above by way of illustration, it will be apparent to those skilled in the art that modifications may be made to the described embodiment in various ways without departing from the spirit and scope of the utility model. The drawings and description are illustrative in nature and should not be construed as limiting the scope of the utility model as claimed.
