[0037] The drill rod tube 2 is a hollow tubular structure;

[0038] The sample discharging head 6 is arranged inside the drill pipe 2;

[0039] One end of the sample discharging handle 3 is connected to the sample discharging head 6, and the other end extends outside the drill pipe 2 from the sliding groove 7;

[0040] The drill bit 9 is connected to the bottom end of the drill pipe 2.

[0041] In some embodiments, it further includes:

[0042] A grip 1, and the grip 1 is connected to the top end of the drill pipe 2.

[0043] In some embodiments, rubber anti-slip pads are sleeved outside both the grip 1 and the sample discharging handle 3.

[0044] In some embodiments, it further includes:

[0045] A slider 5, the slider 5 is arranged inside the drill pipe 2, and the sample discharging head 6 is connected to the lower end of the slider 5;

[0046] A connecting rod, one end of the connecting rod is connected to the slider 5, and the other end passes through the sliding groove 7 and is connected to the sample discharging handle 3.

[0047] Specifically, when the sample discharging handle 3 moves, the connecting rod is located inside the sliding groove 7.

[0048] In some embodiments, it further includes:

[0049] Limit grooves 4, there are at least two limit grooves 4, which are arranged inside the drill pipe 2, connected to the inner wall of the drill pipe 2, and extend along the length direction of the drill pipe 2;

[0050] Limit protrusions are arranged on the side surface of the slider 5, and the limit protrusions are coupled with the limit grooves 4.

[0051] Specifically, the slider 5 has limit protrusions with the same size as the limit grooves 4, and when the slider 5 moves, the limit protrusions are located inside the limit grooves 4.

[0052] Specifically, the slider 5 can be circular, and there can be two limit grooves 4 and limit protrusions, and the two are symmetrically arranged.

[0053] In some embodiments, it further includes:

[0054] Limit rods, there are at least two limit rods, which are arranged inside the drill pipe 2, connected to the inner wall of the drill pipe 2, and extend along the length direction of the drill pipe 2;

[0055] Through holes or grooves penetrating up and down are arranged on the slider 5, and the limit rods pass through the through holes or grooves.

[0056] In some embodiments, the sample discharging head 6 is made of rubber material;

[0057] The sample discharging head 6 is connected to the lower end of the slider 5 by a screw, or the upper end of the sample discharging head 6 and the lower end of the slider 5 are connected by a thread.

[0058] In some embodiments, the outer side surface of the sample discharging head 6 is closely attached to the inner wall of the drill pipe 2.

[0059] Specifically, it is used to scrape out all the ore powder adhering to the inner wall of the drill pipe 2.

[0060] In some embodiments, a threaded connection portion 8 is provided at the bottom end of the drill pipe 2. The threaded connection portion 8 is provided with an internal thread structure, and the outer wall of the drill bit 9 is provided with an external thread structure. The drill bit 9 and the drill pipe 2 are detachably connected through the thread structure.

[0061] The working principle of the mine sampling drill provided by the embodiment of the present application:

[0062] First, connect and fix the drill bit 9 to the threaded connection portion 8 through the thread structure. After ensuring the fixation, move the sample discharging handle 3 to the uppermost position of the sliding groove 7; hold the position of the anti-slip pad on the grip 1 with the hand, and the anti-slip pad will increase the friction between the hand and the grip 1 part, so that it will not slide. After forming a certain angle between the sampling drill and the ground, insert the drill pipe 2 into the ore pile. When reaching a certain depth, pull out the sampling drill. After aligning the drill pipe 2 with the sample receiving bucket, hold the position of the anti-slip pad on the sample discharging handle 3 and apply a downward force. At this time, the sample discharging handle 3 will drive the slider 5 and the sample discharging head 6 to move downward, and push the ore sample out of the drill pipe 2 and into the sample receiving bucket, thus completing the sampling operation of the ore sample. After the sampling is completed, the drill pipe can be immersed in clean water, hold the position of the anti-slip pad on the sample discharging handle 3, and then move it up and down repeatedly. The sample discharging head 6 can scrape and wash the inner wall of the drill pipe 2 clean, avoiding cross-contamination caused by the residual ore powder during the next sampling. Under long-term work, usually the drill bit 9 will bear a great pressure, so part of the drill bit 9 is likely to be damaged, affecting its use. At this time, the drill bit 9 can be unscrewed in a counterclockwise manner and removed for replacement. Similarly, the top end of the sample discharging head 6 and the lower part of the slider 5 are also connected by a thread. When the sample discharging head 6 is worn, the sample discharging head 6 can be unscrewed in a counterclockwise manner and removed for replacement. The replaced drill bit 9 and sample discharging head 6 will not affect their normal use, greatly increasing the service performance of the sampling drill.

[0063] In summary, compared with the prior art, the technical solution of the present application is beneficial to scraping out all the ore powder adhering to the inner wall of the drill pipe when sampling ore powder with relatively high moisture and viscosity by setting a rubber sample discharging head that is closely attached to the inner wall of the drill pipe, ensuring the integrity of the ore powder sample, and thus guaranteeing the accuracy of the inspection of the ore powder sample.

[0064] For common sampling drills, there is no cleaning tool. After use, the inner wall of the drill pipe is often not thoroughly cleaned, and the ore powder remaining on the inner wall of the drill pipe is likely to cause cross-contamination of ore samples, resulting in inaccurate inspection of ore powder samples.

[0065] The sample unloading head of the technical solution of this application can also be used as a cleaning device. After sampling, the drill pipe can be immersed in clean water, and then the sample unloading head 6 can be repeatedly moved up and down to scrape and clean the inner wall of the drill pipe 2, avoiding cross-contamination caused by the ore powder remaining during the next sampling.

[0066] For common sampling drills which are integrally formed, the drill bit of the sampling drill cannot be replaced. When sampling some ore samples with high hardness, the drill bit is often damaged. Due to the non-replaceability of the drill bit, the sampling drill cannot be used after the drill bit is damaged.

[0067] In this application, through the cooperation of the external thread and the internal thread, it is beneficial that the drill bit of the sampling drill is easily damaged due to long-term work. When damaged, the drill bit can be removed from the drill body of the sampling drill by rotating the thread, and then replaced, greatly increasing its usability and ensuring that the damage of the drill bit does not affect the entire drill body.

[0068] In addition, in this application, through the provision of an anti-slip pad, when using the sampling drill for work, it is beneficial to hold the part of the drill body provided with the anti-slip pad by hand during work, greatly increasing its friction and ensuring that the sampling will not fail due to the over-slippery drill body during the use of the sampling drill.

[0069] Note that unless otherwise directly stated, all features disclosed in this specification (including any appended claims, abstract, and drawings) can be replaced by alternative features for achieving the same, equivalent, or similar purposes. Therefore, unless otherwise clearly stated, each disclosed feature is only an example of a group of equivalent or similar features. In the case of use, further, preferably, furthermore, and more preferably are simply the starting points for elaborating another embodiment based on the foregoing embodiment. The content following the further, preferably, furthermore, or more preferably in combination with the foregoing embodiment constitutes the complete composition of another embodiment. The components that can be arbitrarily combined among several further, preferably, furthermore, or more preferably settings following the same embodiment form another embodiment.

[0070] In the implementation of functions and steps, the corresponding functions and steps in each embodiment can also occur in an order different from that shown. For example, two consecutive functions and steps can actually be executed or implemented basically in parallel, and sometimes they can also be executed or implemented in the reverse order, depending on the functions involved.
