Description
Technical field
The utility model mining high-voltage coal mining auxiliary equipment relates to a kind of mining development machine drill bit servicing unit, belongs to mining machinery auxiliary equipment field.Be particularly related to a kind of development machine drill bit servicing unit that utilizes water under high pressure and high-pressure spiral gas.
Background technology
The development machine that present mining exploitation is used leans on the rotation of rotary head to advance, and when running into the high inclination-angle super high seam a little less than the penetrability of drill bit, and drill bit is stuck in the coal seam easily, and production efficiency is reduced.The high speed rotation of drill bit can produce heat and very big dust, the application life of having reduced drill bit.
Summary of the invention
In order to improve above-mentioned situation; It is a kind of through water under high pressure and high-pressure spiral gas that the utility model mining high-voltage coal mining auxiliary equipment provides; Improve the servicing unit of development machine drill bit to high inclination-angle super high seam penetrability; The exploitation difficult problem can be solved during to the high inclination-angle super high seam, the application life of drill bit can be effectively improved.
The utility model mining high-voltage coal mining auxiliary equipment is achieved in that the utility model mining high-voltage coal mining auxiliary equipment is made up of power linkage, sealed bearing device, sealing and connecting device and high-pressure spiral propulsion plant four parts.The power linkage is made up of power shell, taper bit, shell screw hole, last ventilating pipe, following ventilating pipe and water service pipe; Taper bit places the power shell outside; The water delivery appendix places the power enclosure, screw hole inside the shell, power shell and bearing screw hole are fixed with screw.The sealed bearing device is made up of bearing, bearing screw hole and bearing groove, and bearing groove places bearing inner.Sealing and connecting device by sealing cylinder, on seal air vent, sealing limbers, lower seal air vent, sealing circular discs and circular screw hole and form.Sealing cylinder places the circular discs top, is respectively equipped with in sealing cylinder inside to seal air vent, lower seal air vent and sealing limbers, and circular screw hole and bearing screw hole are fixed through screw.The high-pressure spiral propulsion plant is made up of screw hole, rotational shell, last spiral air duct, following spiral air duct, taper venthole and outlet conduit.The spiral air duct places conical shell inboard respectively up and down, has the taper venthole in the conical shell outside, and outlet conduit places the propulsion plant middle part and is connected with the limbers, and spiral case is connected with sealed chassis.
During use; At first the power shell is connected with the development machine rotating shaft and rotates; The power shell drives the spiral case rotation through sealed bearing simultaneously, and the high pressure gas that high-pressure pump produces is transported to helical duct through appendix, discharges through the taper air vent; Water under high pressure is transported to outlet conduit by water service pipe, the discharge water jet.Combine the penetrability of the impact force of water under high pressure and the impact raising drill bit that high pressure gas produces during rotation, reach and improve the penetrability of drill bit, increase the purpose of drilling life of bit the high inclination-angle super high seam.
Beneficial effect
One, with low cost, be easy to promote.
Two, simple in structure, the convenient use.
The thickness that three, can adapt to different coal, the vibrations of high pressure gas make coal layer loosening more be prone to exploitation, improve production efficiency.
