Abstract
This utility model belongs to rotary drilling rig equipment technical field, a kind of two-door the bottom of a pan drilling bucket.When solving the sand mold soil layer that caking property such as running into flour sand is little, mobility is the biggest, the problem that major part boring mud can spill the hole bottom drilling bucket, including drilling bucket cylinder, drilling bucket cylinder bottom connects drilling bucket base plate, described drilling bucket baseplate underside is provided with excavation pawl, on drilling bucket base plate, symmetry has two fan-shaped mouths, being hingedly connected with on the upside of drilling bucket base plate can inwardly folding and can be completely covered by the flabellum of fan-shaped mouth, described flabellum one end is articulated and connected with drilling bucket base plate by bearing pin, and another end cap of flabellum is on drilling bucket base plate.This utility model has can effectively clean out boring mud, it is ensured that drilling and forming hole, shortens the construction period, reduces construction cost, improves the feature of construction quality.
Description
Technical field
This utility model belongs to rotary drilling rig equipment technical field, a kind of two-door the bottom of a pan drilling bucket.
Background technology
The drill bit of rotary drilling rig has the bottom of a pan drilling bucket.This bottom of a pan drilling bucket range is wider, and low cost is widely used.During practice of construction, common two-door the bottom of a pan drilling bucket can normally work when running into the soil layers such as clay, but when running into the sand mold soil layer that the caking property such as flour sand are little, mobility is the biggest, major part boring mud can spill the hole bottom drilling bucket, it is retained in boring, delay the progress of creeping into, affect the pore-forming time.If again changing the drilling bucket being suitable for this sand mold soil layer, construction cost will be increased, and extend the duration.
Summary of the invention
When this utility model is in order to solve to run into the caking property such as flour sand are little, mobility is the biggest sand mold soil layer, the problem that major part boring mud can spill the hole bottom drilling bucket, it is provided that a kind of two-door the bottom of a pan drilling bucket.
This utility model takes techniques below scheme: a kind of two-door the bottom of a pan drilling bucket, including drilling bucket cylinder, drilling bucket cylinder bottom connects drilling bucket base plate, described drilling bucket baseplate underside is provided with excavation pawl,, on drilling bucket base plate, symmetry has two fan-shaped mouths, and being hingedly connected with on the upside of drilling bucket base plate can inwardly folding and can be completely covered by the flabellum of fan-shaped mouth, described flabellum one end is articulated and connected with drilling bucket base plate by bearing pin, and another end cap of flabellum is on drilling bucket base plate.
Being additionally provided with block on the upside of described drilling bucket base plate, described block is arranged on the rear side of the bearing pin that flabellum is connected with drilling bucket base plate.
Compared with prior art, this utility model solves when running into caking property is little, mobility is big sand mold soil layer in drilling process, cannot the problem of effectively normal drilling and forming hole, therefore, this utility model has can effectively clean out boring mud, it is ensured that drilling and forming hole, shortens the construction period, reduce construction cost, improve the feature of construction quality.

Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, it is described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, 2, a kind of two-door the bottom of a pan drilling bucket, including drilling bucket cylinder 1, drilling bucket cylinder 1 bottom connects drilling bucket base plate 2, being provided with excavation pawl 3 on the downside of described drilling bucket base plate 2, on drilling bucket base plate 2, symmetry has two fan-shaped mouths, and being hingedly connected with on the upside of drilling bucket base plate 2 can inwardly folding and can be completely covered by the flabellum 4 of fan-shaped mouth, described flabellum 4 one end is articulated and connected with drilling bucket base plate 2 by bearing pin, and another end cap of flabellum 4 is on drilling bucket base plate 2.Two flabellums 4 both can ensure that boring mud entered in drilling pipe smoothly, is possible to prevent again boring mud to spill.
As shown in Figure 2,3, being provided with block 5 on the upside of described drilling bucket base plate 2, block 5 is arranged on the rear side of the bearing pin that flabellum is connected with drilling bucket base plate.
The above is preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
