Description

Novel bailing device

Technical Field

The utility model relates to a drilling equipment, concretely relates to novel bailing device.

Background

In the water conservancy drilling process, when drilling into a sand layer and a broken stratum, because of poor powder carrying capacity of clear water or large stratum leakage, the drilling fluid can not normally circulate, sand and rock debris in a hole can not be discharged out of an orifice and are deposited at the bottom of the hole, once the sand setting or the rock debris at the bottom of the hole are too much, a drilling tool can not be placed at the bottom of the hole, repeated drilling work can be generated, time and labor are consumed, the drilling efficiency is reduced, and the sand setting or the rock debris at the bottom of the hole needs to be removed.

The existing method for removing the settled sand or rock debris at the bottom of the hole mainly comprises an elastic piece drill bit and a traditional bailing barrel, the elastic piece drill bit enables the settled sand to enter a rock core pipe through rotary dry drilling, and the elastic piece in the drill bit clamps the settled sand during the drilling so as to realize the bailing effect, so that the method is suitable for rock particles with larger particle size and loose particles; the traditional bailing cylinder realizes the opening and closing of a movable valve clack at the bottom of the traditional bailing cylinder by reciprocating a drill rod column up and down to realize the bailing function, and is suitable for loose sand setting with small particle size; for dense settled sand or rock debris, the two methods have low sand bailing efficiency and effect.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses a novel bailing device.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is:

the utility model provides a novel bailing device, its includes core pipe joint, storage sand pipe and the drill bit of fixed connection in proper order, is equipped with to erode the pipeline corresponding to the drill bit in this storage sand pipe, the upper end of storing up the sand pipe is equipped with the sand setting mouth.

An inner waterway pipeline is arranged through the rock core pipe joint and is fixedly connected with the upper end of the scouring pipeline, and the lower end of the scouring pipeline is fixed in the sand storage pipe through a fixing ring.

The lower end of the flushing pipe extends into the drill bit.

And a sand outlet is formed in the upper end wall surface of the drill bit.

The flushing pipeline is a PVC pipe.

The internal waterway pipeline is a steel pipe.

A filter screen is arranged in the inner waterway pipeline.

The sand setting openings are two and are symmetrically arranged relative to the center line of the sand storage pipe.

The bottom of the sand setting port is an arc-shaped curved surface.

The middle part of the fixing ring is funnel-shaped, and the scouring pipeline is fixed in the middle part of the fixing ring.

The utility model has the advantages that: the utility model discloses simple structure, it is convenient to make, and is with low costs, has solved sand bed, has leaked out and has broken stratum's bailing problem, compares with traditional bailing instrument, has improved bailing success rate and efficiency, can be applied to engineering exploration such as water conservancy, municipal administration, traffic engineering, agricultural, forestry, national soil, ocean.

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

In the embodiment, referring to fig. 1, the novel bailing device provided by this embodiment includes a core barrel joint 1, a sand storage pipe 2 and a drill bit 3 which are fixedly connected in sequence, a flushing pipeline 4 is arranged in the sand storage pipe 2 corresponding to the drill bit 3, and a sand setting port 21 is arranged at the upper end of the sand storage pipe 2.

Run through core pipe joint 1 is equipped with inside waterway pipeline 5, this inside waterway pipeline 5 with the upper end fixed connection who erodes pipeline 4, the lower extreme that should erode pipeline 4 is fixed in this sand storage pipe 2 through solid fixed ring 6.

The lower end of the flushing pipe 4 extends into the drill bit 3.

The upper end wall surface of the drill bit 3 is provided with a sand outlet 31.

The flushing pipeline 4 is a PVC pipe.

The inner waterway pipeline 5 is a steel pipe.

A filter screen is arranged in the inner waterway pipeline 5.

The sand setting openings 21 are two, and the two sand setting openings 21 are symmetrically arranged relative to the central line of the sand storage pipe 2.

The bottom of the sand setting port 21 is an arc-shaped curved surface 22.

The middle part 61 of the fixing ring 6 is funnel-shaped, and the flushing pipe 4 is fixed to the middle part 61 of the fixing ring 6.

The rotary power is transmitted to the drill bit 3 through the drill string, the loose bottom sand setting or the rock debris is drilled, meanwhile, the pump is started to transmit flushing fluid to the bottom of the hole through the flushing pipeline 4, the hole bottom sand setting or the rock debris is further flushed, sand grains or the rock debris are carried upwards from a gap between the sand bailing device and the hole wall, the drill string is lifted up and down, the sand grains or the rock debris enter the sand storage pipe 2 from sand setting ports 21 on two sides of the upper portion of the sand storage pipe 2, and the operation is repeated until the hole bottom sand setting or the rock debris is removed.

The utility model discloses simple structure, it is convenient to make, and is with low costs, has solved sand bed, has leaked out and has broken stratum's bailing problem, compares with traditional bailing instrument, has improved bailing success rate and efficiency, can be applied to engineering exploration such as water conservancy, municipal administration, traffic engineering, agricultural, forestry, national soil, ocean.
