Description

Technical Field

[0001] The utility model relates to the field of geological exploration, in particular to a geological exploration coring drill. Background Art

[0002] The existing patent (Announcement No.: CN110823634A) proposes a soil sampling device, including a connecting rod; the upper end of the connecting rod is fixedly arranged on the driving mechanism, and the lower end is detachably connected to the upper end of the drill bit by bolts; a cavity is opened at the connection between the connecting rod and the drill bit; a sampling mechanism is arranged in the cavity; the sampling mechanism includes a sampling motor, a sampling reciprocating screw rod, a sampling sleeve, a sampling connecting rod, a sampling rotating rod and a rotating shaft. However, when the sampling motor of this device starts to work, it drives the sampling reciprocating screw rod to rotate. Since the sampling sleeve cannot rotate, the sampling sleeve moves back and forth up and down at this time, thereby driving the sampling connecting rod to swing back and forth up and down, thereby driving the two sampling rotating rods to swing back and forth outward, so that the soil of the depth can be excavated into the cavity. However, this sampling method cannot ensure that the soil can enter the cavity smoothly, and it is relatively cumbersome, and the entire device needs to be driven by a motor, which is not convenient to carry. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a geological exploration coring drill which ensures that samples will not fall out and is suitable for sampling peat or softer mud. The lengths of the arc connecting plates and the arc semi-closed plates can be customized into different specifications according to research needs. The device is small in size and easy to carry.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A coring drill for geological exploration comprises a lower drill bit of the drill, a lower positioning rod, an arc-shaped connecting plate, a connecting plate side limit plate, an upper connecting column, a rotating plug column, a handle, a sliding block, a positioning plug column, an upper positioning rod, and an arc-shaped semi-closing plate.

Beneficial Effects

[0008] 1. The lower positioning rod on the upper part of the lower drill bit of the drilling tool of the utility model plays a role in positioning and preventing the sampled soil from falling off. The lower drill bit of the drilling tool is connected to the upper connecting column through an arc-shaped connecting plate to form a lower drilling tool. The side limit plate of the connecting plate plays a role in preventing the drilling tool from rotating during the sampling operation after the drilling tool is lowered into the ground during geological exploration and coring. The upper positioning rod and the lower positioning rod cooperate up and down to position and prevent the sampled soil from falling off. The positioning clamping column is inserted into the U-shaped inner groove, and the U-shaped rotating plate is connected to the arc-shaped semi-clamping plate. The arc-shaped semi-clamping plate is positioned by the positioning clamping column and the U-shaped rotating plate, so that the upper inner side surface of the arc-shaped semi-clamping plate is always in contact with the upper connecting column, so as to prevent the arc-shaped semi-clamping plate from being disconnected from the upper connecting column under the pressure of the soil during geological exploration and coring.

[0009] 2. The utility model inserts the rotating plug column into the semicircular slot, and the bottom of the rotating plug column is magnetic, which prevents the rotating plug column from sliding out of the circular slot during geological exploration and coring. The sliding block is connected to the bottom of the rotating plug column.

Then the drilling tool is taken out, and the arc-shaped semi-closed plate is rotated to open to take out the sample. The inclined slider is inserted into the annular slot. The inclined slider is an inclined structure. The lower part of the semi-clamping plate is limited so that the inner side of the lower part of the arc-shaped semi-clamping plate is tightly attached to the drill bit under the drilling tool, and the arc-shaped semi-clamping plate is prevented from being disconnected from the drill bit under the pressure of the soil during geological exploration and coring. The drilling tool is manually operated. The drilling tool is first pressed into a specified depth, and then the arc-shaped semi-clamping plate is rotated in the correct direction to allow peat to enter between the arc-shaped connecting plate and the arc-shaped semi-clamping plate, ensuring that the sample will not fall out. The device is suitable for taking peat or softer soil. The lengths of the arc-shaped connecting plate and the arc-shaped semi-clamping plate can be customized into different specifications according to research needs. The device is small in size and easy to carry. BRIEF DESCRIPTION OF THE DRAWINGS
