Abstract

The utility model discloses a jump ring corer, including drill bit, drill barrel, set up in core barrel in the drill barrel, the core barrel is formed by the concatenation of core barrel one, core barrel two that are half circular, core barrel lower extreme is provided with rather than grafting complex jump ring seat, be provided with the jump ring on the jump ring seat. The utility model discloses simple structure, convenient to use. Through designing into two semi-circular mosaic structures with the core pipe, convenient and fast has made things convenient for the rock core in the core pipe to take out after getting the core from the underground. The utility model discloses the practicality is strong, has simplified the rock core and has bored the back from the underground and take out the process for the construction progress has shortened construction period, lowers construction cost.

Description

Clamp spring corer

Technical Field

The utility model relates to a core equipment technical field is got in the probing specifically indicates a jump ring corer.

Background

Core drilling is a commonly used exploration means for geological exploration of solid minerals. The cylindrical drill bit and the drilling tool crush rock at the bottom of the hole in a circular mode along the circumference, a columnar rock core is reserved in the center of the bottom of the hole, and the rock core is taken out from the hole and used for researching the geology and mineral products.

At present, in the geological core drilling and coring process, a common tool for clamping a core comprises a clamp spring, a clamp spring seat, a stop spring and a stop spring seat. However, in the coring construction process of the clamp spring or the blocking spring, the problem that the core is taken out complexly after being drilled from the underground exists, so that the construction progress is slow, the construction period is long, and the construction cost is high.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a jump ring corer, includes drill bit, a drill section of thick bamboo, set up in core barrel in the drill section of thick bamboo, the core barrel is formed by the core barrel one that is semicircle form, the concatenation of core barrel two, core barrel lower extreme is provided with rather than grafting complex jump ring seat, be provided with the jump ring on the jump ring seat.

As an improvement, the core tube is cut into a first core barrel and a second core barrel which are matched with each other along the axial direction of the core tube, the outer rings of the lower ends of the first core barrel and the second core barrel are respectively provided with a first conical surface matched with the clamp spring seat, and the inner ring of the upper end of the clamp spring seat is provided with a second conical surface matched with the first conical surface.

As an improvement, the clamp springs are multiple and sleeved on the clamp spring seat.

After the structure more than adopting, the utility model has the advantages of as follows: the utility model discloses simple structure, convenient to use. Through designing into two semi-circular mosaic structures with the core pipe, convenient and fast has made things convenient for the rock core in the core pipe to take out after getting the core from the underground. The utility model discloses the practicality is strong, has simplified the rock core and has bored the back from the underground and take out the process for the construction progress has shortened construction period, lowers construction cost.

Drawings

Fig. 1 is a schematic structural view of the jump ring coring device of the present invention.

Figure 2 is the utility model discloses a jump ring corer core tube's structural schematic.

Fig. 3 is a schematic structural view of the clamp spring seat of the clamp spring coring device of the present invention.

As shown in the figure: 1. the drill bit comprises a drill bit body 2, a drill barrel 3, a core barrel 3.1, a core barrel I, a core barrel II, a core barrel 3.2, a conical surface I, a conical surface II, a conical surface 5 and a clamp spring.

Detailed Description

Combine 1 ~ 3 of the attached drawing, a jump ring corer, including drill bit 1, drill barrel 2, set up in core barrel 3 in the drill barrel 2, core barrel 3 is formed by the core barrel 3.1, the core barrel 3.2 concatenation that is the semicircle form, 3 lower extremes of core barrel are provided with rather than grafting complex jump ring seat 4, be provided with jump ring 5 on the jump ring seat 4.

As a preferred embodiment of this embodiment, the core barrel 3 is cut along the axial direction thereof into a first core barrel 3.1 and a second core barrel 3.2, which are engaged with each other, the outer rings of the lower ends of the first core barrel 3.1 and the second core barrel 3.2 are respectively provided with a first tapered surface 3.3 engaged with the circlip seat 4, and the inner ring of the upper end of the circlip seat 4 is provided with a second tapered surface 4.1 engaged with the first tapered surface 3.3.

As a preferred embodiment of the present embodiment, the plurality of circlips 5 are sleeved on the circlip seat 4.

The utility model discloses when concrete implementation, the drill bit, bore a section of thick bamboo, the mutually supporting of jump ring seat is bored coring core to core barrel from the underground, and core barrel pull back of coming, can directly open core barrel one, core barrel two and take out the intraductal rock core of rock core, and is simple and convenient.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
