Description

Technical Field

[0001] The utility model belongs to the technical field of exploration equipment, in particular to a land resource exploration equipment. Background Art

[0002] After searching, Chinese patent CN217786600U discloses a land exploration device with a movable inner rod body, so that the handle is always at the most comfortable height for the human body, which is convenient for sampling personnel to take samples and easy to store; the limit ring is movable, and the drilling depth is set before sampling. When the limit ring touches the fixed cylinder, the switch is turned off, and sampling at a specific depth can be carried out, making the sampling data more accurate.

[0003] The above-mentioned device has shortcomings: Although the above-mentioned scheme can achieve a fixed-depth drilling sampling operation, it has obvious limitations, that is, the downward drilling driving force is simply achieved by manual pressure. In the current actual work process of land resource exploration, extremely complex geological conditions are often encountered, especially rock layers with higher hardness. When facing such hard rock layers, the force generated by manual pressure to move the drill bit downward is extremely weak and insufficient. The output of human power is relatively limited, and it is difficult to break through the high-strength resistance of the rock layer and provide sufficient penetration force for the drill bit, resulting in the drill bit being unable to effectively penetrate the rock layer and continue to go deep underground. In this way, the entire drilling sampling work will inevitably stagnate and cannot operate smoothly as expected, seriously affecting the efficiency and progress of the exploration work, and greatly limiting the wide application of the device under various geological conditions. It is difficult to meet the exploration needs of comprehensive and in-depth sampling and analysis of different stratigraphic structures. Utility Model Content

[0005] The downward pressure structure includes two symmetrically distributed guide rods and a limit plate located in front of the sleeve, and a mounting plate located behind the sleeve. A servo motor is installed on the inner bottom wall of the mounting plate. The output end of the servo motor is fixedly connected to a screw rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model adopts the design of the drilling structure and the downward pressure structure, so that when drilling exploration, the abutment block slides to the required drilling depth, and then the screw and the abutment block are locked to the outside of the limit plate by the locking ring, at this time the servo motor is started to drive the screw to rotate, thereby driving the threaded block and the sliding plate to move downward, at this time the sliding plate, the extension block and the sliding block move downward synchronously until the sliding block moves to the top surface of the abutment block, at this time the drill bit and the driving motor move downward, and the drill bit is driven by the starting drive motor to rotate, thereby achieving drilling at a fixed depth and when encountering a rock layer with higher hardness, the servo motor, with its powerful torque output capacity and precise speed control function, continuously and stably provides sufficient downward force for the threaded block, the sliding plate, the driving motor and the drill bit, so that it can overcome the huge resistance of the rock layer and move downward stably, thereby ensuring that the drill bit always maintains the best drilling state in the high hardness rock layer, which not only ensures the drilling efficiency but also prolongs the service life of the drill bit.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the utility model provides a land resource exploration device, comprising a sleeve 1, a drilling structure 2 located inside the sleeve 1, and a pressing structure 3 located outside the sleeve 1;

[0022] The downward pressure structure 3 includes two symmetrically distributed guide rods 31 and a limit plate 32 located in front of the sleeve 1, and a mounting plate 33 located behind the sleeve 1. A servo motor 34 is installed on the inner bottom wall of the mounting plate 33. The output end of the servo motor 34 is fixedly connected to a screw rod 35. The outer wall of the screw rod 35 is rotatably connected to a threaded block 36. A sliding groove that slides with the threaded block 36 is opened on the outer wall of the mounting plate 33.

[0023] The above scheme is adopted: through the design of the drilling structure 2 and the pressing structure 3, when drilling exploration is carried out, the abutment block 26 is slid to the required drilling depth, and then the screw 27 and the abutment block 26 are locked to the outside of the limit plate 32 by the locking ring 28. At this time, the servo motor 34 is started to drive the screw 35 to rotate, thereby driving the threaded block 36 and the sliding disk 21 to move downward. At this time, the sliding disk 21, the extension block 24 and the sliding block 25 move downward synchronously until the sliding block 25 moves to the top surface of the abutment block 26. At this time, the drill bit 23 and the drive motor 22 move downward, and the servo motor 34 is started to drive the screw 35 to rotate, thereby driving the threaded block 36 and the sliding disk 21 to move downward. The dynamic drive motor 22 drives the drill bit 23 to rotate, thereby achieving fixed-point depth drilling and when encountering rock layers with higher hardness, the servo motor 34, with its powerful torque output capability and precise speed control function, continuously and stably provides sufficient downward force to the threaded block 36, the sliding disk 21, the drive motor 22 and the drill bit 23, so that they can overcome the huge resistance of the rock layer and move downward stably, thereby ensuring that the drill bit 23 always maintains the best drilling state in the high-hardness rock layer, which not only ensures the drilling efficiency but also extends the service life of the drill bit 23.

[0024] like Figures 1 to 5 As shown, the top of the screw rod 35 is rotatably connected to the inner top wall of the mounting plate 33, and four guide grooves 11 are provided on the outer wall of the sleeve 1. The drilling structure 2 includes a sliding disk 21 located on the inner wall of the sleeve 1 and a drive motor 22 assembled on the bottom of the sliding disk 21, and a drill bit 23 fixedly connected to the output end of the drive motor 22. The outer wall of the sliding disk 21 is fixedly connected to an extension block 24 that slides between the guide grooves 11, and a sliding block 25 outside the sliding disk 21 and located in front of the threaded block 36.

[0025] The above solution is adopted: the top of the screw rod 35 is rotatably connected to the inner top wall of the mounting plate 33. This connection method ensures the stability of the screw rod 35 during rotation, reduces errors caused by shaking or offset, and thus improves the accuracy of drilling. Moreover, through the rotation of the screw rod 35 and the movement of the threaded block 36, the position of the sliding disk 21, the drive motor 22 and the drill bit 23 can be easily adjusted to adapt to the drilling requirements of different depths. The four guide grooves 11 are slidably adapted to the extension block 24 fixed to the outer wall of the sliding disk 21, which not only limits the rotational freedom of the sliding disk 21, but also ensures its stable movement in the vertical direction, further improving the accuracy and stability of drilling.

[0026] like Figures 1 to 5 As shown, an abutment block 26 is provided below the sliding block 25, which is in contact with the sliding block 25 and is slidably connected to the inner wall of the limiting plate 32. A screw 27 is installed on the outer wall of the abutment block 26, and a locking ring 28 is connected to the external thread of the screw 27. The abutment block 26 is locked to the outside of the limiting plate 32 through the locking ring 28.

[0027] The above solution is adopted: the abutment block 26 is slid on the outside of the limit plate 32, and the abutment block 26 is slid to the required drilling depth by observing the scale marking line, and then the locking ring 28 is rotated on the outside of the screw 27 to fix the abutment block 26 on the outside of the limit plate 32.

[0028] like Figures 1 to 5 As shown, it also includes a base plate 4 located at the bottom of the sleeve 1 and a spike 5 installed at the bottom of the base plate 4. The outside of the limit plate 32 is provided with a scale marking line. The threaded block 36 is fixedly connected to the sliding disk 21, and the extension blocks 24 located on the left and right sides of the sleeve 1 are provided with through holes that are slidably adapted to the guide rod 31.

[0029] Adopting the above scheme: the spike 5 significantly enhances the contact force between the device and the ground, effectively preventing the device from sliding or offsetting due to uneven force during the drilling process, thereby greatly improving the accuracy of drilling, especially on soft or uneven ground, the spike 5 can also play a key fixing role, ensuring that the device can be firmly placed and drilling operations can be carried out. In addition, the scale marking line set on the outside of the limit plate 32 provides an intuitive and clear reference for the operator, allowing the operator to easily and accurately adjust the drilling depth, further improving the efficiency and accuracy of the drilling operation.

[0030] The working principle of this utility model:

[0031] First, place the device at the land location to be explored, so that the spikes 5 at the bottom of the bottom plate 4 penetrate the ground to ensure that the device is stable. Then, according to the drilling depth required for exploration, by observing the scale mark line on the outside of the limit plate 32, manually slide the abutment block 26 to the corresponding position on the inner wall of the limit plate 32, and then rotate the locking ring 28 on the screw 27 to firmly fix the abutment block 26 on the outside of the limit plate 32. After the preparation work is completed, start the servo motor 34 on the inner bottom wall of the mounting plate 33. The servo motor 34 drives the screw rod 35 to rotate. Since the screw rod 35 is threadedly connected to the threaded block 36, and the threaded block 36 can only slide along the slide groove on the outer wall of the mounting plate 33, the rotation of the screw rod 35 will cause the threaded block 36 to move downward, thereby driving the fixed connection therewith. The sliding disc 21 moves down. At this time, the extension block 24 on the outer wall of the sliding disc 21 slides down steadily along the guide groove 11 of the sleeve 1, and the sliding block 25 in front of the sliding disc 21 also moves down synchronously until the sliding block 25 moves to the top surface of the abutment block 26. At this time, the drill bit 23 and the drive motor 22 begin to move down, and the drive motor 22 is started. Its output end drives the drill bit 23 to rotate at high speed to start the drilling operation. During the drilling process, if a rock layer with higher hardness is encountered, the servo motor 34, with its powerful torque and precise speed control function, continuously provides sufficient downward force for the threaded block 36, sliding disc 21, drive motor 22 and drill bit 23 to overcome the rock resistance and keep the drill bit 23 in the best drilling state until the predetermined drilling depth is reached and the drilling task is completed.
