Abstract
An efficient discharge medium-soft rock diamond composite blade bit is composed of a drilling bit steel body, a diamond composite blade, a centre hole, a water tank and a water tank pore. The drilling bit steel body is the main component. The top end of the drilling bit steel body is provided with the diamond composite blade with the tilting mode. The diamond composite blade can be divided into three groups, a tilting water tank with the same rotating direction of the drilling bit is arranged between the diamond composite blades. The center of the drilling bit steel body is provided with the centre hole. The corresponding position of the water tank is provided with a big chamfer angle. The rock powder is cut down in the drilling process of the drilling bit and can be discharged upward along the rotating direction of the drilling bit and along the arc shaped water tank without being obstructed when arriving at the big chamfer angle, therefore the balling phenomenon can be avoided. The efficient discharge medium-soft rock diamond composite blade bit of the utility model has simple integrated structure and easy processing, and is especially suitable to the drilling of the medium-soft rock; the efficient discharge medium-soft rock diamond composite blade bit has high efficiency, fast drilling speed and low cost, and can widely applied to the drilling to the soft rock of coal, oilfield and all kinds of mineral resources under the well.
Description
Technical field: the utility model relates to the boring diamond compact bit of mine down hole drill, relates in particular to soft rock diamond compact bit in efficient row's powder.
Background technology: the diamond compact bit of prior art, owing to adopt straight hole formula tank, when the middle incompetent bed that creeps into about 5 grades, rock dust is discharged difficulty, takes place easily to stick with paste to bore, and causes rate of penetration to be fallen slowly, efficient reduces, to such an extent as to and occur the burning of bits easily and make drill bit phenomenon such as scrap.
The utility model content: the purpose of this utility model is, overcomes the deficiencies in the prior art part, and soft rock diamond compact bit in a kind of efficient row's powder is provided, and is applicable to creeping into of incompetent bed in the multiple rank, and rate of penetration is fast, the efficient height.Soft rock diamond compact bit in efficient row's powder described in the utility model includes drill steel body, diamond compact, centre bore, tank and tank hole and forms.Said drill steel body is the main component of soft rock diamond compact bit in efficient row's powder described in the utility model, top at the drill steel body is provided with diamond compact with the inclination form, said diamond compact divides does three groups, between each group, be provided with the tank of inclination, be divided into and make three groups of tanks, tank is circular arc on the whole, and is consistent with the direction of rotation of drill bit.The center of drill steel body is provided with centre bore, and the correspondence position of tank is provided with a big chamfering.Rock dust under drill bit cuts in drilling process can be along the circular arc tank, upwards discharges along the direction of rotation of drill bit, when arriving big chamfering owing to there is not the dead angle, so can be not interrupted.The centre of drill bit is provided with centre bore, and is unobstructed up and down, makes the middle rock dust that do not have of drill bit be detained.Respectively be provided with a tank hole in three tanks of drill bit, High-Pressure Water is by the ejection of the tank hole in three tanks, the rock dust that cuts along the discharge of taking advantage of a situation of the tank of circular arc, is made that the rock dust in the tank can not be detained, thereby avoids sticking with paste the generation of boring phenomenon.
Soft rock diamond compact bit in efficient row's powder described in the utility model, overall structure is simple, and is easy to process, be particularly suitable for creeping into of middle incompetent bed, the efficient height, rate of penetration is fast, cost is low, can be widely used in the creeping into of soft rock in all kinds of mineral reserve down-holes such as coal, oil.
Description of drawings: accompanying drawing 1 is the overall structure schematic diagram of soft rock diamond compact bit in efficient row's powder described in the utility model; Accompanying drawing 2 is the structural representations at drill bit top.1-drill steel body 2-diamond compact 3-centre bore 4-tank 5-tank hole
The specific embodiment: referring now to accompanying drawing 1 and accompanying drawing 2, be described as follows in conjunction with the embodiments: soft rock diamond compact bit in efficient row's powder described in the utility model includes drill steel body 1, diamond compact 2, centre bore 3, tank 4 and tank hole 5 and forms.Said drill steel body 1 is the main component of soft rock diamond compact bit in efficient row's powder described in the utility model, top at drill steel body 1 is provided with diamond compact 2 with the inclination form, said diamond compact was done three groups in 2 minutes, between each group diamond compact 2, be provided with the tank 4 of inclination, be divided into and make three groups of tanks 4, tank 4 is circular arc on the whole, consistent with the direction of rotation of drill bit, that is to say, between each group diamond compact 2, be provided with the inclination tank 4 consistent with the direction of rotation of drill bit.The center of drill steel body 1 is provided with centre bore 3, and the correspondence position of tank 4 is provided with a big chamfering.Rock dust under drill bit cuts in drilling process can be along the tank 4 of circular arc, upwards discharges along the direction of rotation of drill bit, can be not interrupted when arriving big chamfering.The centre of drill bit is provided with centre bore 3, and is unobstructed up and down, makes the middle rock dust that do not have of drill bit be detained.Respectively be provided with a tank hole 5 in three tanks 4 of drill bit, High-Pressure Water is by 5 ejections of three tank holes, the rock dust that cuts along the discharge of taking advantage of a situation of the tank 4 of circular arc, is made that the rock dust in the tank 4 can not be detained, thereby avoids sticking with paste the generation of boring phenomenon.Soft rock diamond compact bit in efficient row's powder described in the utility model, overall structure is simple, and is easy to process, be particularly suitable for creeping into of middle incompetent bed, the efficient height, rate of penetration is fast, cost is low, can be widely used in the creeping into of soft rock in all kinds of mineral reserve down-holes such as coal, oil.
