Description

Technical Field

[0001] The utility model relates to the field of mine auxiliary equipment, in particular to a handheld mine drilling sampling device. Background Art

[0002] Mining drilling sampling belongs to core sampling, also known as core drilling sampling, which is the sampling work carried out on the core or ore core obtained by drilling. It is generally done by manual or mechanical methods, according to a certain sampling length, splitting the core into two halves or four parts along the long axis, and then taking half or one quarter of it as a sample.

[0003] At present, when manual sampling is carried out, due to the hard texture of the rock, the operator is required to stabilize the drilling equipment during the drilling and sampling process. When manually stabilizing, it is not only necessary to prevent the driving device of the drilling and sampling device from rotating during operation, but also the entry of the sampling head needs to be stabilized axially to avoid deviation.

[0004] Since the operating power of the drilling sampling device is relatively high during the drilling sampling process, the operator needs to use a lot of force to stabilize the drilling equipment during manual positioning, which not only has a poor stabilization effect, but also requires a huge amount of labor. Utility Model Content

[0005] The utility model aims to provide a handheld mining drilling sampling device to solve the problems of difficult manual stabilization and poor positioning effect of the existing handheld drilling equipment.

[0006] In order to solve the above problems, the utility model adopts the following technical means:

[0007] A handheld mining drilling sampling device, comprising:

[0008] A sampling mechanism for drilling sampling of rock walls;

[0009] A positioning mechanism, used for firmly positioning with the rock wall, and having a plurality of drilling positioning parts;

[0010] There are three drilling positioning parts, which are arranged in a triangular distribution. The drilling positioning parts are arranged on the plate body of the positioning mechanism, and the sampling end of the sampling mechanism is arranged at the center position of the triangle formed by the three drilling positioning parts;

[0011] The power end of the sampling mechanism is linearly slidably connected to the mounting portion of the positioning mechanism, and the sliding direction of the sampling mechanism is arranged parallel to the drilling direction of the drilling positioning portion.

[0012] Preferably, the sampling mechanism includes a sampling drill bit as the sampling end. One end of the sampling drill bit is coaxially connected to the rotational output end of the power end. The other end of the sampling drill bit is configured with a material channel extending axially. The outer wall of the sampling drill bit is configured with a spiral edge and a chip removal groove.

[0013] Furthermore, an exhaust channel is configured inside the sampling drill bit. One end of the exhaust channel penetrates from the end of the material channel, and the other end of the exhaust channel penetrates from the outer side wall of the sampling drill bit at a position located at the end of the spiral edge and the chip removal groove.

[0014] Furthermore, the positioning mechanism includes a positioning box as the installation part. The positioning box is installed at the central position of the plate body. Both ends of the positioning box are provided with through holes. The sampling mechanism is arranged inside the positioning box. The sampling mechanism includes a first rotating motor as the power end. The power output end of the first rotating motor is connected to the sampling end. Slide rods are respectively installed on one pair of opposite outer walls of the first rotating motor, and limiting rods are respectively installed on the other pair of opposite outer walls;

[0015] A sliding channel for the slide rod to extend out is configured on the side wall of the positioning box. The extending direction of the sliding channel is parallel to the drilling direction of the drilling positioning part. A bearing plate for holding by hand is installed at the end of the slide rod passing through the positioning box;

[0016] A limiting chute for the limiting rod to extend into is configured on the inner side wall of the positioning box. The end of the limiting rod is slidably arranged inside the limiting chute. The extending direction of the limiting chute is the same as the linear movement direction of the sampling mechanism.

[0017] Furthermore, a compression spring is provided on the side of the bearing plate facing the plate body. Both ends of the compression spring are respectively in contact with the plate body and the bearing plate. A limiting column is installed on the plate body. The limiting column is inserted into the compression spring. A through hole for the limiting column to pass through is provided on the bearing plate.

[0018] Furthermore, the drilling positioning part is installed on the plate body. The drilling positioning part includes a rotating rod rotatably installed on the plate body. A second rotating motor is provided at one end of the rotating rod. The rotating end of the second rotating motor is coaxially connected to the rotating rod. A punching head is coaxially installed at the other end of the rotating rod. The punching head is used for drilling.

[0019] Furthermore, the second rotating motor is fixedly connected to the plate body through a connecting rod. The three second rotating motors are set to start and stop synchronously.

[0020] Furthermore, a handle is installed on the side wall of the plate body.

[0021] During the use of the utility model, the following beneficial effects are achieved:

[0022] During sampling, first hold the positioning mechanism by hand, turn on the drilling and positioning part of the positioning mechanism, let the drilling and positioning part drill holes, and let the drilling end of the drilling and positioning part drill holes, and let the drilling end of the drilling and positioning part gradually penetrate into the mine wall. When all three drilling and positioning parts reach the established depth, turn off the drilling and positioning part, and use the insertion of the three drilling and positioning parts to position the entire device. After positioning, turn on the sampling mechanism, manually push the sampling mechanism, let the sampling end of the sampling mechanism travel along the drilling direction of the drilling and positioning part, and let the sampling end of the sampling mechanism contact the mine wall for sampling.

[0023] In this way, not only can the drilling and positioning parts in triangular positioning be used to stably position the power end of the sampling mechanism during the sampling process, avoiding its movement and rotation following the sampling end. At the same time, the linear sliding connection between the power end of the sampling mechanism and the installation part of the positioning mechanism can be used to make the displacement of the sampling mechanism during the sampling process more accurate, avoiding the deviation of the sampling end of the sampling mechanism during the sampling process, resulting in the fracture of the sampling end or poor sampling effect.

[0035] Please refer to Figures 1 to 4As shown in the figure, a handheld mine drilling and sampling device includes:

[0036] A sampling mechanism 1 for drilling and sampling the rock wall;

[0037] A positioning mechanism 2 for stably positioning with the rock wall, and is constructed with several drilling positioning parts 3;

[0038] There are three of the drilling positioning parts 3, which are arranged in a triangular distribution. The drilling positioning parts 3 are arranged on the plate body 22 of the positioning mechanism 2, and the sampling end of the sampling mechanism 1 is arranged at the center position of the triangle formed by the three drilling positioning parts 3;

[0039] The power end of the sampling mechanism 1 is linearly slidably connected to the installation part of the positioning mechanism 2, and the sliding direction of the sampling mechanism 1 is parallel to the drilling direction of the drilling positioning part 3.

[0040] In this way, during sampling, first hold the positioning mechanism 2 by hand, turn on the drilling positioning part 3 of the positioning mechanism 2, let the drilling positioning part 3 drill, and let the drilling end of the drilling positioning part 3 drill, and let the drilling end of the drilling positioning part 3 gradually penetrate into the mine wall. When all three drilling positioning parts 3 enter the established depth, turn off the drilling positioning part 3, and use the insertion of the three drilling positioning parts 3 to realize the positioning of the whole device. After the positioning is completed, turn on the sampling mechanism 1, manually push the sampling mechanism 1, let the sampling end of the sampling mechanism 1 travel along the drilling direction of the drilling positioning part 3, and let the sampling end of the sampling mechanism 1 contact the mine wall to perform sampling.

[0041] Thus, not only can the power end of the sampling mechanism 1 during the sampling process be stably positioned by the drilling positioning parts 3 in triangular positioning, avoiding its movement and rotation following the sampling end. At the same time, the linear sliding connection between the power end of the sampling mechanism 1 and the installation part of the positioning mechanism 2 can make the displacement of the sampling mechanism 1 during sampling more accurate, avoiding the situation that the sampling end of the sampling mechanism 1 deviates during sampling, resulting in the fracture of the sampling end or poor sampling effect.

[0042] Furthermore, for the sampling mechanism 1, the sampling mechanism 1 includes a sampling drill bit 11 as the sampling end. One end of the sampling drill bit 11 is coaxially connected to the rotational output end of the power end, the other end of the sampling drill bit 11 is constructed with a material channel 12 extending along the axial direction, and the outer wall of the sampling drill bit 11 is constructed with a spiral edge 13 and a chip removal groove 14.

[0043] In this way, as the sampling drill bit 11 penetrates during sampling, the sample material enters the material channel 12 for collection, which is convenient for the operator to collect the sample after sampling is completed.

[0044] Furthermore, an exhaust passage 4 is formed inside the sampling drill bit 11. One end of the exhaust passage 4 penetrates from the end of the material passage 12, and the other end of the exhaust passage 4 penetrates from the outer wall of the sampling drill bit 11 at a position where the spiral edge 13 and the end of the chip removal groove 14 are located.

[0045] In this way, the exhaust passage 4 is used to facilitate the sampling material to enter the material passage 12. To avoid the formation of a pressure holding cavity in the material passage 12 during the entry of the sample material.

[0046] At the same time, the arrangement of the through port of the exhaust passage 4 can also effectively reduce the risk of the exhaust passage 4 being blocked by particulate materials.

[0047] Furthermore, for the positioning mechanism 2, the positioning mechanism 2 includes a positioning box 21 as the installation part. The positioning box 21 is installed at the central position of the plate body 22. Both ends of the positioning box 21 are provided with through holes. The sampling mechanism 1 is arranged inside the positioning box 21. The sampling mechanism 1 includes a first rotating motor 5 as the power end. The power output end of the first rotating motor 5 is connected to the sampling end. A sliding rod 6 is respectively installed on one pair of opposite outer walls of the first rotating motor 5, and a limiting rod 7 is respectively installed on the other pair of opposite outer walls;

[0048] A sliding channel 8 for the sliding rod 6 to extend out is formed on the side wall of the positioning box 21. The extending direction of the sliding channel 8 is parallel to the drilling direction of the drilling positioning part 3. One end of the sliding rod 6 passing through the positioning box 21 is installed with a carrying plate 9 for holding by hand;

[0049] A limiting sliding groove 10 for the limiting rod 7 to extend into is formed on the inner side wall of the positioning box 21. The end of the limiting rod 7 is slidably arranged in the limiting sliding groove 10. The extending direction of the limiting sliding groove 10 is the same as the linear movement direction of the sampling mechanism 1.

[0050] In this way, during the sampling process after positioning, only by pushing the carrying plate 9 forcefully, the sampling drill bit 11 as the sampling end can be linearly moved. Under the dual effects of the sliding channel 8 and the limiting sliding groove 10, it is effectively avoided that the sampling drill bit 11 is deflected during the drilling sampling process.

[0051] Furthermore, during the actual operation process, when the sampling drill bit 11 penetrates deeper, the operator can apply force to the sampling mechanism 1 more easily. However, when the sampling drill bit 11 is withdrawn, only the pulling force of the operator can be used to push it out, which causes difficulties in withdrawing the sampling drill bit 11. To facilitate the withdrawal of the sampling drill bit 11, a compression spring 15 is provided on the side of the bearing plate 9 facing the plate body 22. The two ends of the compression spring 15 are respectively in contact with the plate body 22 and the bearing plate 9. A limiting post 16 is installed on the plate body 22, and the limiting post 16 is inserted into the compression spring 15. A through hole for the limiting post 16 to pass through is provided on the bearing plate 9.

[0052] In this way, with the action of the compression spring 15 and in cooperation with the outward pulling force of the operator, the sampling drill bit 11 can be withdrawn better. Utilizing the resilience of the compression spring 15 to assist the operator in withdrawing the sampling drill bit 11.

[0053] Furthermore, for the drilling positioning part 3, the drilling positioning part 3 is installed on the plate body 22. The drilling positioning part 3 includes a rotating rod 31 rotatably installed on the plate body 22. One end of the rotating rod 31 is provided with a second rotating motor 32, and the rotating end of the second rotating motor 32 is coaxially connected to the rotating rod 31. The other end of the rotating rod 31 is coaxially installed with a drilling head 33 for drilling.

[0054] In this way, driven by the second rotating motor 32, the drilling head 33 rotates, and the operator pushes the plate body 22 inward, enabling the drilling head 33 to drill holes.

[0055] Furthermore, the second rotating motor 32 is positioned and connected to the plate body 22 through a connecting rod, and the three second rotating motors 32 are set to start and stop synchronously.

[0056] At the same time, to facilitate the operator's application of force when using the drilling positioning part 3 for drilling, a handle 17 is installed on the side wall of the plate body 22.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
