Abstract
The utility model discloses a powdered coal coring device, which belongs to a coal exploration coring device. The powdered coal coring device comprises a core outer pipe, a reducing joint, a coring drill bit, a single-acting device and a core inner pipe, wherein the reducing joint is in rigidity connection with the inner wall of the upper end of the core outer pipe, the coring drill bit is in rigidity connection with the outer wall of the lower end of the coring outer pipe, the single-acting device is in rigidity connection with the lower end of the reducing joint, the core inner pipe is in rigidity connection with the lower end of the single-acting device, a flow guide hole is arranged inside the reducing joint, the outer wall of the lower end of the core inner pipe is in rigidity connection with a clamp spring base, a clamp spring and a clamp spring fixing ring are arranged inside the clamp spring base, the upper portion of the clamp spring fixing ring is fixed with the lower end of a transparent plastic lining, and the transparent plastic lining is arranged inside the core inner pipe. The powdered coal coring device has the following advantages that during usage, the lining containing a powdered coal core is directly dragged, thereby not only keeping original shape of the powdered coal core, but also bringing convenience for visual description, storage and transportation.
Description
Technical field
The utility model belongs to the geological exploration techniques field, relates to the special-purpose coring tool of a kind of geological prospecting aspect, particularly a kind of fine coal corer.
Background technology
The coal heart is the primary data that we are familiar with coalfield and bottom.Taking the coal heart is a very important job in coal exploration and the exploitation.For obtaining the coal heart, need use corer.At present, widely used corer mainly is made up of inside and outside basket in coal exploration.When taking the coal heart, the fine coal heart directly enters pipe inside in the rock core, can not guarantee the original stratiform of the coal heart when taking out the coal heart, is not easy to geological personnel and carries out directviewing description, more is not easy to storage and transportation.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of fine coal corer with transparent flexible plastic inner lining is provided, when core bit is taked the fine coal coal heart, the fine coal heart directly enters transparent plastic liner inside, the liner that will accommodate the fine coal heart when taking out the coal heart is directly managed hauling-out in rock core, both can keep the original stratiform of the fine coal heart, be convenient to the geological personnel directviewing description again, and be convenient to storage and transportation.
For achieving the above object, the technical solution adopted in the utility model is: it comprises the rock core outer tube, with the rigidly connected reducing joint of rock core outer tube upper end inwall, with the rigidly connected core bit of rock core outer tube lower end outer wall, manage in the rock core be rigidly connected single action device and be rigidly connected of reducing joint lower end with single action device lower end, described reducing joint inside is provided with pod apertures, pipe lower end outer wall and clip spring seat are rigidly connected in the described rock core, it is characterized in that: described clip spring seat inside is equipped with jump ring and jump ring retainer ring, described jump ring retainer ring top and transparent plastic liner lower end are fixed, and described transparent plastic liner places pipe inside in the rock core.
Described single action device is a thrust bearing.
Pipe is made up of by being threaded hollow circular tube and upper end cover in the described rock core.
The utility model compared with prior art has the following advantages: the liner that accommodates the fine coal heart directly can be hauled out during use, both keep the original stratiform of the fine coal heart, be convenient to the geological personnel directviewing description again, and be convenient to storage and transportation.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
As shown in Figure 1, the utility model comprises rock core outer tube 1, with the rigidly connected reducing joint 2 of rock core outer tube 1 upper end inwall, with the rigidly connected core bit 3 of rock core outer tube 1 lower end outer wall, with be rigidly connected single action device 5 and be rigidly connected with single action device 5 lower ends and manage 6 in the rock core of reducing joint 2 lower ends, described reducing joint 2 inside are provided with pod apertures 4, pipe 6 lower end outer walls and clip spring seat 10 are rigidly connected in the described rock core, described clip spring seat 10 inside are equipped with jump ring 9 and jump ring retainer ring 8, described jump ring retainer ring 8 tops and transparent plastic liner 7 lower ends are fixed, and described transparent plastic liner 7 places pipe 6 inside in the rock core.Described single action device 5 is a thrust bearing.Pipe 6 is made up of hollow cylinder and upper end cover in the described rock core, and hollow cylinder is threaded with upper end cover.
During use, fine coal corer upper end is linked to each other with the drilling rod lower end by screw thread, core bit is promoted to ground with the fine coal corer after taking the fine coal coal heart.Pipe does not have the transparent plastic liner in the conventional corer rock core, when core bit is taked the fine coal coal heart, the fine coal heart directly enters pipe inside in the rock core, in the time will taking out the coal heart, need the fine coal in the pipe in the rock core bit by bit be pounded out with instrument, the distribution at random of fine coal after the taking-up can not keep its original stratiform.Pipe inside is provided with the transparent plastic liner in the utility model rock core, when core bit is taked the fine coal coal heart, the fine coal heart directly enters transparent plastic liner inside, in the time will taking out the coal heart, the transparent plastic liner that accommodates the fine coal heart is directly managed hauling-out in rock core, both keep the original stratiform of the fine coal heart, be convenient to the geological personnel directviewing description again, and be convenient to storage and transportation.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
