Abstract
The utility model discloses a plowshare drill, which mainly comprises a drill stem, a protective ring and a drill corner. The protective ring is disposed on the drill stem, the drill corner is located at the front end of the drill stem, and plowshares are disposed among the drill stem, the protecting ring and the drill corner. In order to increase penetration speed, the further scheme includes that the plowshares are divided into at least two groups and are arranged on the drill stem up and down at intervals, and each group comprises two plowshares which are symmetrically arranged on the drill stem. The optimized scheme includes that the groups of plowshares are perpendicularly arranged spatially. The plowshare drill can effectively get rid of viscosity constraint of clay during drilling, thereby being capable of effectively increasing penetration speed.
Description
Technical field
The utility model relates to a kind of drill bit, especially a kind of colter drill bit.
Background technology
Stake machine (as 10 type stake machines) drill bit general on the market is three leaf drill bits, when the construction argillic horizon, adopts the stake machine penetration rate of this drill bit slower, is generally 1 meter/hour.Find that after deliberation cause the slower main cause of penetration rate to be that structure is comparatively closely knit in the drill bit, the space in the drill bit member is less.And in drilling process, because clay viscosity is bigger, very easily be stuck between the gap, even strengthen the clear water consumption, also be difficult to make its rotation to come off, in case and reality is filled in the gap between drill bit, when continuing to creep into, because of clay can't obtain enough clear water pulping circulations, resistance increases, thereby makes rate of penetration slow down greatly.
Summary of the invention
The purpose of this utility model is a kind of colter drill bit that can effectively get rid of the stickiness constraint of unsticking soil when creeping into that provides for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the colter drill bit that the utility model is designed, it mainly comprises drilling rod, guard ring and brill angle, guard ring is arranged on the drilling rod, bores the angle and is positioned at the drilling rod front end, is provided with colter in the position on the drilling rod, between guard ring and the brill angle.
In order further to improve penetration rate, further scheme is described colter at least two groups, is up and down to be provided with at interval on drilling rod; Every group comprises two colters, and these two colters are at drilling rod and are symmetrical arranged.Preferred scheme is spatially to be vertical setting between described colter group and the group.
As preferably, the downward-sloping setting of described colter.
In order further to improve penetration rate, as preferably, described colter is made of two vertically interconnective again mutually plough sheets.
In order to reach more good drilling effect,, be welded with alloy on described colter and/or the brill angle as preferably; Described plough sheet is preferably iron plate; Described brill angle is preferably rhombus and bores the angle; Described guard ring is the steel guard ring.
The colter drill bit that the utility model obtains can effectively get rid of the stickiness constraint of unsticking soil, thereby can effectively improve penetration rate when creeping into.

The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As shown in Figure 1, the described colter drill bit of present embodiment, it mainly comprises drilling rod 1, guard ring 2 and bores angle 3, guard ring 2 is arranged on the drilling rod 1, bore angle 3 and be positioned at drilling rod 1 front end, on the drilling rod 1, guard ring 2 is provided with colter 4 with position between the brill angle 3.
As shown in Figure 2, the described colter drill bit of present embodiment, it comprises that mainly drilling rod 1, steel guard ring and rhombus bore angle 3, the steel guard ring is arranged on the drilling rod 1, drives mud when mainly being the guard ring rotation, plays the retaining wall effect, rhombus bores angle 3 and is positioned at drilling rod 1 front end, plays " pioneer " and creeps into effect.On the drilling rod 1, guard ring 2 and the position of boring between the angle 3 be provided with two groups of colters 4, described colter 4 downward-sloping settings, and two groups of colters 4 are on drilling rod 1 up and down and are provided with at interval; Every group comprises two colters 4, and these two colters 4 are at drilling rod 1 and are symmetrical arranged.Spatially be vertical setting between 4 groups on described colter and the group.
The described colter drill bit of present embodiment, spacing is bigger between the colter 4, forms active porosity, can effectively get rid of the stickiness constraint of unsticking soil when drill bit creeps into, and then keep optimum mud circulation, guarantees effective drilling depth.
As the improvement of present embodiment, colter 4 is also established and can be designed to three groups, four groups or more.
Shown in Fig. 3,4,5,6, the described colter drill bit of present embodiment, described as different from Example 2 colter 4 is made of two vertically interconnective again mutually plough sheets 5, and described plough sheet 5 is an iron plate, solid is triangle arranges, can play effective broken clay effect.
Self structure of colter 4 and the distribution on drilling rod 1 are can remain valid in the clay keys of drilling depth of the described colter drill bit of present embodiment, spacing is bigger between the colter 4, form active porosity, when creeping into, can effectively get rid of on drill bit the stickiness constraint of unsticking soil, and then keep optimum mud circulation, guarantee effective drilling depth.Through on-the-spot test, in argillic horizon, aircraft footage per bit can remain on 2 meters/hour, increases work efficiency greatly.
As shown in Figure 7, the described colter drill bit of present embodiment all is provided with alloy 6 on described as different from Example 3 colter 4 and the brill angle 3, thereby can reaches more good drilling effect.
Alloy 6 also can be only to be arranged on to bore on the angle 3 or on the colter 4.
