Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and more specifically, to geological drilling and sampling equipment for geological exploration. Background Technology

[0002] Geological surveying is a technical means of studying the geological structure, resource distribution and engineering geological conditions of the earth's surface and underground through field investigation, data collection and analysis. Its core objective is to provide a scientific basis for resource development, engineering construction and disaster prevention. In the process of geological surveying, geological drilling and sampling equipment is needed to drill and sample deep soil layers.

[0003] However, in actual use, traditional geological drilling and sampling equipment for geological exploration mostly requires drilling holes on the ground at the required depth using drill rods, then removing the drill rods and using sampling equipment to take samples. The sampling process is very cumbersome and cannot sample soil at different depths without removing the drill rods, which greatly reduces the applicability of drilling and sampling equipment. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a geological drilling and sampling device for geological exploration, so as to solve the problem that the sampling process in the prior art is very cumbersome and it is impossible to sample soil at different depths in segments without removing the drill rod.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a geological drilling and sampling device for geological exploration, including a mobile frame, an electric slide rail seat vertically embedded on the mobile frame, a reinforcing docking frame fixed on the electric slide rail seat, an installation frame fixed on one side of the reinforcing docking frame, a first motor fixed inside the installation frame, a bottom frame fixed to the end of the output shaft of the first motor, a drill rod for drilling holes in the ground embedded at the bottom of the bottom frame, and an automatic segmented sampling component for use with the drill rod inside the bottom frame.

[0006] The automatic segmented sampling component includes two sets of vertical plates inserted sequentially into the drill rod in the left-right direction. Each set of vertical plates has a horizontal frame fixed at its top. The front and back of the bottom frame are fixed with side frames. A second motor is embedded in one set of side frames. A U-shaped drive frame is fixed at the end of the output shaft of the second motor. Both ends of the U-shaped drive frame are inserted into the corresponding horizontal frame. A Z-shaped storage trough is opened at the bottom of each set of vertical plates.

[0007] One of the side frames is equipped with an electric push rod. The piston rod of the electric push rod is fixed to a Z-shaped positioning pressure frame whose bottom is attached to the vertical insert plate and the top of the horizontal frame. The bottom of the Z-shaped positioning pressure frame has a chamfer on the front.

[0008] The Z-shaped positioning frame has slides fixed on both sides of its top, and the bottom frame cavity has a sliding groove at its top that slides with the slides.

[0009] The bottom of the mobile frame is evenly provided with multiple sets of auxiliary positioning holes for the insertion of ground nails and external rods, and each set of auxiliary positioning holes has an inwardly inclined structure.

[0010] The bottom of one side of each set of vertical inserts is inclined.

[0011] The output shaft end of the first motor is located on the same vertical axis as the drill rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the above scheme, by setting up an automatic segmented sampling component, the Z-shaped storage trough can be alternately moved down to the bottom of the drill rod using vertical inserts that can move alternately. With the rotational power provided by the first motor, the soil below the drill rod can quickly enter the Z-shaped storage trough and fill it. The vertical inserts can then be reset to seal and preserve the soil sample at that depth. At this time, the use of multiple sets of vertical inserts makes it convenient to sample soil at different depths according to the needs of geological survey. After sampling, the soil sample can be directly sealed and preserved, which can effectively prevent soil from other depths from mixing in, thereby improving the overall sampling accuracy of the equipment. Moreover, the entire sampling process is very simple, without the need to frequently remove the drill rod, thus improving the applicability of the borehole sampling equipment.

[0015] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0016] Example: Please refer to Figures 1 to 7 This utility model provides a technical solution: a geological drilling and sampling device for geological exploration, including a mobile frame 1. A controller is embedded in the push frame on the top left side of the mobile frame 1. An electric slide rail 2 is vertically embedded in the mobile frame 1. Multiple sets of auxiliary positioning holes 18 are evenly opened at the bottom of the mobile frame 1 for inserting ground nails and external rods. The design of the auxiliary positioning holes 18 is to allow ground nails or external rods to pass through and be inserted into the ground to assist in positioning the mobile frame 1, thereby improving the overall stability of the mobile frame 1. Each set of auxiliary positioning holes 18 has an inwardly inclined structure, and the inclined design of the auxiliary positioning holes 18 allows ground nails or external rods to be directly inserted obliquely into the ground, which further improves the positioning effect of the mobile frame 1. A reinforcing docking frame 3 is fixed on the electric slide rail 2 via the slide rail. A mounting frame 4 is fixed on one side of the reinforcing docking frame 3. A first motor 5 is fixed inside the mounting frame 4. A bottom frame 6 is fixed to the end of the output shaft of the first motor 5. A drill rod 7 for drilling holes in the ground is embedded at the bottom of the bottom frame 6. The end of the output shaft of the first motor 5 and the drill rod 7 are located on the same vertical axis so that the first motor 5 can drive the drill rod 7 to rotate stably and synchronously, avoiding the vertical axis deviation, so that the drill rod 7 will revolve along the end of the output shaft of the first motor 5 as a whole, which will affect the drilling effect. An automatic segmented sampling assembly for use with the drill rod 7 is provided inside the bottom frame 6. The automatic segmented sampling assembly includes two sets of vertical plates 11 inserted into the drill rod 7 in the left and right directions. The bottom of one side of each set of vertical plates 11 is inclined so that the vertical plates 11 can be inserted into the soil without obstruction. The inclined surface can reduce the adhesion of the upper soil layer and improve the subsequent sampling accuracy. A horizontal frame 12 is fixed at the top of each set of vertical plates 11. Side frames 8 are fixed on the front and back of the bottom frame 6. A second motor 9 is embedded on one set of side frames 8. A U-shaped drive frame 10 is fixed at the end of the output shaft of the second motor 9. Both ends of the U-shaped drive frame 10 are inserted into the corresponding horizontal frame 12. A Z-shaped storage trough 17 is opened at the bottom of each set of vertical plates 11. By setting up an automatic segmented sampling component and using the second motor 9, the angle of the U-shaped drive frame 10 can be changed. With the assistance of the transverse frame 12, the vertical positions of the two sets of vertical insert plates 11 can be adjusted synchronously and in opposite directions. This allows one set of vertical insert plates 11 to be lowered and inserted into the soil below the drill rod 7, exposing the Z-shaped storage trough 17 on it. The other set is moved upward by a certain distance. At this time, the rotational force provided by the first motor 5 can drive the drill rod 7 and the vertical insert plates 11 to rotate, allowing the soil in this position to quickly enter the Z-shaped storage trough 17. The drill rod 7 is filled with soil, and with the assistance of the second motor 9, the two sets of vertical plates 11 can be reset, so that the soil at this depth can be quickly sampled and sealed for preservation. The design of multiple sets of vertical plates 11 makes it easy to sample soil at different depths according to geological survey needs. After sampling, the soil sample can be directly sealed for preservation, which can effectively prevent soil from other depths from mixing in, thereby improving the overall sampling accuracy of the equipment. The whole sampling process is very simple and does not require frequent removal of the drill rod 7, which improves the applicability of the drilling sampling equipment. Another set of side frames 8 is equipped with an electric push rod 13. The piston rod of the electric push rod 13 is fixed with a Z-shaped positioning pressure frame 14 whose bottom is attached to the top of the vertical insert plate 11 and the horizontal frame 12. The design of the electric push rod 13 allows for free control of the position of the Z-shaped positioning pressure frame 14. This allows for auxiliary positioning of the top of the vertical insert plate 11 and the horizontal frame 12 when the bottom ends of both sets of vertical insert plates 11 are housed inside the drill rod 7. This prevents the soil from continuously impacting the vertical insert plate 11 during drilling, which could easily cause the vertical insert plate 11 to shift. Consequently, it would continuously provide pushing force to the U-shaped drive frame 10, making it easier for the U-shaped drive frame to... To ensure long-term stable operation of the equipment, the Z-type positioning frame 14 is equipped with slides 15 on both sides of its top. The top of the inner cavity of the bottom frame 6 is provided with a sliding groove 16 that slides with the slides 15. The design of the slides 15 and the sliding groove 16 allows for sliding positioning of the Z-type positioning frame 14, further improving the pressing stability of the Z-type positioning frame 14 on the vertical insert plate 11 and the horizontal frame 12. The bottom of the Z-type positioning frame 14 is chamfered on the front. The chamfer design allows the Z-type positioning frame 14 to be stably engaged with the top of the vertical insert plate 11 and the horizontal frame 12, avoiding obstruction.

[0017] The working process of this utility model is as follows: In the initial state, the electric push rod 13 pushes the Z-shaped positioning clamp 14 to engage with the vertical insert plate 11 and the horizontal frame 12, limiting the position of the vertical insert plate 11 and preventing excessive stress on the U-shaped drive frame 10. At this time, the user moves the entire equipment to the location to be surveyed and activates the electric slide rail 2 and the first motor 5 through the controller. With the assistance of the bottom frame 6, the first motor 5 drives the drill rod 7 to rotate, and the electric slide rail 2 controls the reinforcing docking frame 3, the mounting frame 4, the bottom frame 6, and the drill rod 7 to move down synchronously. This allows drilling into the ground. Once the bottom of the drill rod 7 reaches the required sampling depth, the user controls the Z-shaped positioning frame 14 to move backward via the electric push rod 13, disengaging it from the vertical insert plate 11 and the horizontal frame 12, thus releasing their constraints. Simultaneously, the second motor 9 drives the U-shaped drive frame 10 to rotate. With the assistance of the horizontal frame 12, one set of vertical insert plates 11 can be driven downward and inserted into the soil below the drill rod 7, exposing the Z-shaped storage trough 17 on it. At the same time, the other set of vertical insert plates 11... Simultaneously, the drill rod 7 moves upward and backward a certain distance, while the first motor 5 continues to drive the drill rod 7 to rotate. This drives the downward-moving vertical insert 11 to rotate synchronously, allowing the soil at the bottom of the drill rod 7 to quickly enter and fill the Z-shaped storage trough 17. Subsequently, the user controls the U-shaped drive frame 10 to reset via the second motor 9, thereby controlling the two sets of vertical inserts 11 to reset. At this time, the Z-shaped storage trough 17, filled with soil samples, will move synchronously into the drill rod 7, allowing for rapid sampling and sealing of soil at that depth. Following the above method, the user drives the drill rod 7 to continue moving downward to the next sampling point to sample soil at another depth. After sampling, the soil samples can also be directly sealed and preserved, effectively preventing soil from other depths from mixing in, improving the overall sampling accuracy of the equipment. The entire sampling process is very simple, eliminating the need to frequently remove the drill rod 7, thus improving the applicability of the drilling sampling equipment. After sampling is completed, the user controls the drill rod 7 to reset and controls the two sets of vertical inserts 11 to alternately move downward via the second motor 9 to remove the soil samples.
