Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 to 3, the utility model discloses a prevent drill of sealing 1, including preventing drill pipe 12 and drill bit 11 of sealing, prevent drill pipe tail end 124 of sealing for the drilling rod link end of being connected with other drilling rods, prevent drill pipe head end 123 of sealing with the drill bit 11 tail end is connected, prevent that drill pipe head end 123 of sealing is the drill bit link end promptly, prevent to be equipped with the through-hole 122 that leads to row sediment medium on the drill pipe 12 of sealing. In order to prevent the drill covering, the outer surface of the drill covering prevention rod 12 is provided with a spiral groove 121 screwed in the direction opposite to the drilling rotation direction of the drill bit 11.
The method of determining the screwing direction of the spiral groove 121 is the same as the method of determining the screwing direction of the screw. The outer surface of the anti-covering drill rod 12 is provided with a spiral groove 121 screwed in the direction opposite to the drilling rotation direction of the drill bit 11, that is, when the drilling rotation direction of the drill bit 11 is clockwise, the spiral groove 121 is left-handed (see fig. 1), and when the drilling rotation direction of the drill bit 11 is counterclockwise, the spiral groove 121 is right-handed. Since the drilling machine drills holes in a clockwise rotation mode, the spiral groove 121 formed in the anti-jamming drill rod 12 is in a left-handed rotation mode. The number of the spiral grooves 121 can be one, and the spiral grooves 121 are three in the figure, so that slag can be discharged more quickly by three spiral grooves than by 1 spiral groove. Of course, the number of the spiral grooves 121 may be any other number.
As shown in fig. 4, the anti-trepanning clockwise rotary drill hole is taken as an example. During drilling, the slag discharging medium 14 is introduced from the anti-sealing drill rod and is discharged from a drilling hole, when large drilling slag passes through the spiral groove 121 along with the slag discharging medium 14, the reaction force applied to the drilling slag is larger due to the fact that the reaction force applied to the drilling slag is smaller than the reaction force applied to the drilling slag due to the fact that the reaction force applied to the drilling slag is larger due to the fact that the reaction force applied to the drilling slag is smaller than the reaction force applied to the spiral groove 121, and therefore large drilling cuttings generated by cutting of a drill bit cannot easily enter a slag discharging channel through the spiral groove 121 until the large drilling cuttings are crushed by the drill bit 11, slag discharging resistance is. When the drill bit rear collapses or collects more drill cuttings to cause difficulty in deslagging, the drill rod is retreated and rotated to prevent sealing, the blockage is rolled and reversely pushed by the aid of the screw, the blockage is crushed and pushed into the bottom of the hole, the drill bit is retreated to form a space, so that the drill bit and the drill rod are withdrawn, drilling is dredged, drilling accidents can be prevented from occurring, and drilling speed is guaranteed.
The anti-covering drill bit 11 and the anti-covering drill rod 12 may be of an integral structure or a split structure. Preferably, the drill bit 11 and the anti-covering drill rod 12 are of a split structure, and are detachably connected, and in the embodiment of the figure, a threaded connection is specifically adopted, but may be inserted. Adopt and to dismantle the connection, be convenient for change alone and prevent covering drilling rod or drill bit.
The outer diameter c of the spiral groove 121 gradually decreases from the head end 123 of the anti-covering drill rod to the tail end 124 of the anti-covering drill rod. So that the anti-covering drill rod 12 is similar to a cone, the resistance of the anti-covering drill rod to retreat can be reduced, and the retreat dredging drilling of the anti-covering drill rod is more convenient.
As shown in fig. 2 and 3, the spiral angle of the spiral groove 121 gradually increases from the head end 123 of the anti-casing drill rod to the tail end 124 of the anti-casing drill rod. Therefore, the downward extrusion force and the extrusion speed of the tail end of the spiral groove 121 on the drilling slag or the collapsed hole wall are both greater than the downward extrusion force and the extrusion speed of the tail end of the spiral groove 121 on the drilling slag or the collapsed hole wall, so that the drilling slag or the collapsed hole wall gathered behind the drill bit 11 can be better extruded and rolled. In the same manner, in the direction from the head end 123 of the anti-covering drill rod to the tail end 124 of the 3-preventing covering drill rod, the groove width d of the spiral groove 121 becomes gradually wider, that is, the tail end width of the spiral groove 121 is greater than the head end width. Therefore, the downward extrusion amount of the tail end of the spiral groove 121 to the drilling slag or the collapsed hole wall is larger than the downward extrusion amount of the tail end of the spiral groove 121 to the drilling slag or the collapsed hole wall, so that the drilling slag or the collapsed hole wall gathered behind the drill bit 11 can be better extruded and rolled.
The utility model discloses a prevent the drill stem of sealing and prevent the drill of sealing, the drill of sealing problem that appears during the geology drilling of fine solution to drilling rate can be improved.
