Description

Technical Field

[0001] This utility model relates to the field of geological drilling and exploration technology, and in particular to a geological drilling and exploration device for geological disaster prevention and control. Background Technology

[0002] In geological disaster prevention and control, it may be necessary to use geological drilling exploration equipment to conduct ground drilling exploration, especially when sampling the soil at a depth of about 1 meter below the surface. The soil may vary every 10-20 cm, and excavation is relatively troublesome, and soil samples from different depths are easily interfered with. Currently, traditional geological drilling exploration equipment cannot accurately control the drilling depth during daily use, thus making it impossible to accurately determine the depth for sampling and to sample at the same depth and layer simultaneously. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a geological drilling and exploration device for geological disaster prevention, which solves problems such as the inability to accurately perform layered sampling and precisely control the depth of sampling.

[0004] According to this utility model, a geological drilling and exploration equipment for geological disaster prevention includes a drilling and exploration trolley, a drilling and exploration sampling mechanism, and a controller. The drilling and exploration trolley has four rollers at its bottom, and a ground-inserting pile assembly is installed at each of the four corners of the trolley's bottom. The drilling and exploration sampling mechanism includes a positioning rotary drum, a grooving assembly, and a sampling assembly. A first bearing is fitted onto the outer wall of the positioning rotary drum near its top, and the first bearing is embedded within the drilling and exploration trolley. The bottom of the positioning rotary drum is 15-20 cm above the ground. The grooving assembly includes a grooving drill bit, a second bearing, a grooving motor, a push block, and a push motor. The second bearing is fitted onto the top of the grooving drill bit, and the shaft of the grooving motor is fixedly connected to the top of the grooving drill bit. The second bearing and the grooving motor are both mounted on the side wall of the push block via mounting plates. The positioning rotary drum... The bottom has two deep slots. Two limiting rods movably pass through both sides of the push block, and the two ends of the limiting rods are fixed to the side wall of one of the deep slots. A push screw is connected to the shaft of the push motor. The push screw spirally passes through the middle of the push block. The sampling assembly includes a sampling rod, multiple sampling components evenly spaced on the sampling rod, a fixed-depth moving motor, and a moving screw. The other deep slot has two limiting sleeves at its bottom. The sampling rod movably passes through the two limiting sleeves. The moving screw spirally inserts into the interior from the top of the sampling rod. The shaft of the fixed-depth moving motor is connected to the top of the moving screw. The drilling exploration trolley is equipped with a fine-tuning motor. A fine-tuning gear disk is fitted on the shaft of the fine-tuning motor. A gear belt is provided on the outer wall of the top wall of the positioning drum. The fine-tuning gear disk meshes with the gear belt. The controller is used to control the operation of the equipment.

[0005] In some embodiments of this utility model, the structure of the ground-inserting pile assembly is the same as that of the slotting assembly but different in size, and the structure of the ground-inserting pile drill bit in the ground-inserting pile assembly is the same as that of the slotting drill bit.

[0006] In some other embodiments of this utility model, the sampling component includes an ejector cylinder, a motor sleeve, a cutting motor, and a soil sampling cylinder. The end of the cylinder shaft of the ejector cylinder is fixed with a motor sleeve. The cutting motor is embedded in the motor sleeve. The shaft of the cutting motor is fixed on the rear side wall of the soil sampling cylinder. The soil sampling cylinder is provided with a soil cutting rod at the opening position.

[0007] In some other embodiments of this utility model, the cross-section of the sampling rod is semi-circular at both ends and square in the middle.

[0008] In some other embodiments of this utility model, the longest width of the sampling rod is less than the diameter of the slotting drill bit.

[0009] In this invention, a slotting drill bit is used to create a slot at a fixed depth. The diameter of the slot is greater than the maximum width of the sampling rod, so that the sampling rod can be inserted accurately. After insertion, multiple sampling components set at equal intervals on the sampling rod can be positioned at a precise depth. During sampling, each sampling component extends out of the sampling rod and inserts into the soil to take a sample. Samples from several layers can be taken at once, resulting in good sampling effect. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] Reference Figure 1-4A geological drilling and exploration equipment for geological disaster prevention includes a drilling and exploration trolley 1, a drilling and exploration sampling mechanism, and a controller. The drilling and exploration trolley 1 has four rollers at its bottom, and a ground stake assembly is installed at each of the four corners of the bottom of the drilling and exploration trolley. The drilling and exploration sampling mechanism includes a positioning rotary drum 4, a grooving assembly, and a sampling assembly. The positioning rotary drum 4 has a first bearing 41 fitted on its outer wall near the top, and the first bearing 41 is embedded inside the drilling and exploration trolley 1. The bottom of the positioning rotary drum 4 is 15-20 cm above the ground. The grooving assembly includes a grooving drill bit 3, a second bearing 31, a grooving motor 32, a push block 5, and a push motor 51. The grooving drill bit 3 has the second bearing 31 fitted on its top, and the shaft of the grooving motor 32 is fixedly connected to the top of the grooving drill bit 3. The second bearing 31 and the grooving motor 32 are both mounted on the side wall of the push block 5 via mounting plates. The positioning rotary drum 4 has two deep grooves cut from its bottom. The push block 5 has two limiting rods 53 that movably pass through both sides, and the two ends of the limiting rods 53 are fixed to the side wall of one of the deep grooves. The push motor 51 has a push screw 52 connected to its shaft, and the push screw 52 spirally passes through the middle of the push block 5. The sampling assembly includes a sampling rod 6, multiple sampling components 7 evenly spaced on the sampling rod 6, a fixed-depth moving motor 62, and a moving screw 621. The other deep groove has two limiting sleeves 6 at its bottom. 1. The sampling rod 6 movably passes through two limiting sleeves 61. The downward screw 621 is spirally inserted into the interior from the top of the sampling rod 6. The shaft of the fixed-depth downward motor 62 is connected to the top of the downward screw 621. The drilling exploration trolley 1 is equipped with a fine-tuning motor 8. A fine-tuning gear disk is sleeved on the shaft of the fine-tuning motor 8. A gear belt is provided on the outer wall of the top wall of the positioning rotary drum 4. The fine-tuning gear disk meshes with the gear belt. The controller is used to control the operation of the equipment.

[0019] The drilling trolley is pushed to the geological drilling exploration position. Four ground stake components are inserted into the ground to stabilize the trolley. Before sampling, the push motor is started to slowly drive the push screw 52 to rotate, thereby driving the push block to move downwards. During the downward movement of the push block, the slotting drill bit 3, the second bearing 31, and the slotting motor 32 move downwards synchronously. The slotting motor 32 drives the slotting drill bit 3 to rotate, creating a slot in the soil. After slotting, the drill bit is pulled up and the slot is lowered. At this time, the micro-rotor motor 8 rotates the positioning drum 4 half a turn, positioning the sampling rod 6 directly above the slot. The sampling rod 6 is then lowered to a fixed depth position. Multiple sampling components 7 are then activated to extend and collect samples. After sampling, the sampling rod 6 is retracted and raised. Sampling is complete.

[0020] When taking samples, the ground stake assembly is raised, and the drilling exploration trolley 1 is pushed onto the cleaning and sampling platform. There is sufficient height and space under the platform to allow the trenching assembly and sampling assembly to extend fully, and the sampling component 7 to be extended first for sampling, followed by cleaning of the trenching drill bit 3. After completion, it is raised again to await the next sampling.

[0021] A loose control wire is provided on one side of the push block 5, which can supply power to the slotting motor 32 when the push block 5 moves. The top of the sampling rod 6 is also provided with a loose long control wire. The width of the deep groove is large enough to facilitate the pulling of the control wire for control.

[0022] The structure of the ground-inserting pile assembly is the same as that of the slotting assembly, but the size is different. The ground-inserting drill bit 2 in the ground-inserting pile assembly has the same structure as the slotting drill bit 3. Similar to slotting, after insertion, it waits for sampling to be completed before being raised.

[0023] The sampling component 7 includes an ejector cylinder 71, a motor sleeve 72, a cutting motor 73, and a soil sampling cylinder 74. The end of the cylinder shaft of the ejector cylinder 71 is fixed with the motor sleeve 72. The cutting motor 73 is embedded in the motor sleeve 72. The shaft of the cutting motor 73 is fixed on the rear side wall of the soil sampling cylinder 74. The soil sampling cylinder 74 is provided with a soil cutting rod 75 at the opening position.

[0024] The cylinder 71 is pushed outward to push the motor sleeve 72 outward, the soil sampling cylinder 74 is inserted into the soil, the soil sampling cylinder 74 is rotated, the soil cutting rod 75 cuts the soil and leaves it in the soil sampling cylinder 74, and then it is retracted, and the sampling is completed.

[0025] The cross-section of the sampling rod 6 is semi-circular at both ends and square in the middle. Since the slot is circular, the sampling rod 6 cannot be circular, otherwise it will rotate within the limiting sleeve 61. However, in order to extend more of the soil sampling tube 74 for sampling, the two ends are semi-circular, which makes it easier to extend the soil sampling tube 74 further.

[0026] The longest width of the sampling rod 6 is less than the diameter of the slotting drill bit 3. Insertion is convenient and does not pull on the soil.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
