Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically a portable multi-functional sampling device for hydrogeological and environmental geological exploration. Background Technology

[0002] Hydrogeological and environmental geological exploration plays a crucial role in various fields such as resource development, engineering construction, and environmental protection. In this process, obtaining representative samples is decisive for accurately analyzing geological conditions, assessing environmental impacts, and ensuring project safety. Portable multi-functional sampling devices, as key tools in hydrogeological and environmental geological exploration, can collect various samples, including but not limited to soil, rock, and water samples, in diverse and complex field environments. Their portability allows exploration personnel to work in areas with different topographical features, while their multi-functionality meets the needs of collecting multiple sample types in a single exploration mission, effectively improving the efficiency and quality of exploration work and providing rich data support for subsequent geological analysis.

[0003] In actual hydrogeological and environmental geological exploration, site conditions are complex and varied, including rugged mountains, soft soil, or slippery ground. Traditional sampling drilling rigs are prone to instability such as shaking and deviation during operation. This instability not only affects the accuracy of sampling, resulting in samples that do not accurately reflect the geological conditions, but may also damage the sampling equipment, increasing maintenance costs and the risk of work delays. Therefore, this utility model provides a portable multifunctional sampling device for hydrogeological and environmental geological exploration. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a portable multi-functional sampling device for hydrogeological and environmental geological exploration. It solves the problem that in actual hydrogeological and environmental geological exploration work, where site conditions are complex and variable, traditional sampling drilling rigs are prone to instability such as shaking and deviation during operation. This instability not only affects the accuracy of sampling, but also causes the obtained samples to fail to truly reflect the geological conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable multi-functional sampling device for hydrogeological and environmental geological exploration, comprising a sampling drill, and further comprising:

[0006] A foot-operated folding frame is installed on both sides of the upper end of the sampling drill. The foot-operated folding frame includes a crossbar rotatably installed on both sides of the upper end of the sampling drill, and a hollow rod is fixed at the lower end of the crossbar. A slide rod is slidably installed in the inner cavity of the hollow rod. A foot plate is connected to the bottom end of the slide rod, and a slider is integrally formed on one side of the top end of the slide rod. A groove is provided on one side of the hollow rod for the slider to slide in a directional manner.

[0007] The rotary push unit is located at the lower end of the foot-operated folding frame and is used to drive the foot-operated folding frames on both sides of the sampling drill to rotate and unfold.

[0008] The positioning unit is located inside the foot-operated folding frame and is used to position the slide rod inside the cavity rod.

[0009] Preferably, the rotary pusher unit includes a cavity block and a base block fixedly installed on the sampling drill. A rotating shaft is rotatably installed inside the cavity block, and the top end of the rotating shaft extends to the outside of the cavity block and is fixed to the crossbar.

[0010] Preferably, a gear is fixed on the crossbar, and a rack that meshes with the gear is slidably installed inside the cavity block.

[0011] Preferably, a rotating rod is rotatably mounted on the base block, and the rear of the rotating rod is provided with an external thread. A push rod is threadedly connected to the threaded section of the rotating rod. The push rod is fixed to the rack, so that after the rotating rod rotates, it pushes the push rod to extend and retract back and forth, and drives the rotating shaft to rotate through the rack and gear.

[0012] Preferably, the positioning unit includes a guide rod that passes through and is slidably mounted on the crossbar, a locking post is fixed at the upper end of the guide rod, and a stop bar is fixed at the lower end of the guide rod, and a tension spring is connected between the guide rod and the cavity rod.

[0013] Preferably, the upper end of the sampling drill is fixed with mating columns on both sides, and the mating columns are provided with arc-shaped grooves. When the foot folding frame is unfolded to both sides of the sampling drill, the clamping column can slide against the outer arc surface of the mating column, thereby pulling the guide rod and the stop rod to move horizontally.

[0014] Beneficial effects

[0015] This invention provides a portable, multifunctional sampling device for hydrogeological and environmental geological exploration.

[0016] Compared with existing technologies, it has the following advantages:

[0017] 1. This portable multi-functional sampling device for hydrogeological and environmental geological exploration features a foot-operated folding frame. During deployment, the sliding engagement between the locking pin and the outer arc surface of the mating pin, along with the movement of the stop bar driven by the tension spring, allows the sliding rod to be in a retractable state, providing flexibility for subsequent adjustments. Once deployed, the foot-operated folding frame provides stable support and positioning for the sampling drill. Operators control the overall drilling stability by stepping on the foot pedal. The operation is intuitive and easy to control. Simultaneously, the sliding rod slides along the inner wall of the hollow rod, working in conjunction with the lower part of the drill to penetrate the ground, further enhancing the stability and convenience of the sampling process and contributing to improved quality and efficiency in hydrogeological and environmental geological exploration sampling.

[0018] 2. This portable multi-functional sampling device for hydrogeological and environmental geological exploration features a foot-operated folding frame attached to both sides of the upper end of the sampling drill in its initial state.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a portable multi-functional sampling device for hydrogeological and environmental geological exploration, specifically including the following embodiments:

[0027] Example 1: A portable multi-functional sampling device for hydrogeological and environmental geological exploration, comprising a sampling drill 1, and further comprising: a foot-operated folding frame 2, disposed on both sides of the upper end of the sampling drill 1, the foot-operated folding frame 2 comprising a crossbar 21 rotatably mounted on both sides of the upper end of the sampling drill 1, and a hollow rod 22 fixed at the lower end of the crossbar 21, a slide rod 23 slidably mounted in the cavity of the hollow rod 22, a footplate 24 connected to the bottom end of the slide rod 23, and a slider 25 integrally formed on one side of the top end of the slide rod 23, and a groove provided on one side of the hollow rod 22 for the slider 25 to slide in a directional manner; a rotary push unit 3, disposed at the lower end of the foot-operated folding frame 2, and used to drive the foot-operated folding frames 2 on both sides of the sampling drill 1 to rotate and unfold. The positioning unit 4 is located inside the foot-operated folding frame 2 and is used to position the slide rod 23 inside the cavity rod 22. By operating the rotary push unit 3, the foot-operated folding frame 2 is rotated and unfolded around the rotation connection point between the crossbar 21 and the sampling drill 1. During the unfolding process, the slide rod 23 can slide inside the cavity rod 22, and the slider 25 slides directionally along the slide groove on one side of the cavity rod 22 to ensure the sliding stability of the slide rod 23. The foot pedal 24 allows the staff to easily adjust the support state of the foot-operated folding frame 2 by stepping on it. After the foot-operated folding frame 2 is unfolded to the appropriate position, the positioning unit 4 makes the slide rod 23 change from a fixed state to a telescopic state, so as to cooperate with the lower part of the drill to drill into the ground.

[0028] Example 2: The main difference between this example and the first technical solution is that: a portable multi-functional sampling device for hydrogeological and environmental geological exploration, the rotary push unit 3 includes a cavity block 31 and a base block 36 fixedly installed on the sampling drill rig 1. A rotating shaft 32 is rotatably installed inside the cavity block 31, and the top end of the rotating shaft 32 extends to the outside of the cavity block 31 and is fixed to a crossbar 21. A gear 33 is fixed on the crossbar 21. A rack 34 that meshes with the gear 33 is slidably installed inside the cavity block 31. A rotating rod 37 is rotatably installed on the base block 36, and the rear of the rotating rod 37 is provided with an external thread. A push rod 35 is threadedly connected to the threaded section of the rotating rod 37. The push rod 35 is fixed to the rack 34, so that after the rotating rod 37 rotates, it pushes the push rod 35 to extend and retract back and forth, and through the rack 34... 4. The gear 33 drives the rotating shaft 32 to rotate. When the rotating rod 37 on the rotating base block 36 is rotated, due to the threaded structure of the rotating rod 37, the push rod 35 will move back and forth along the rotating rod 37. The push rod 35 is fixed together with the rack 34. The extension and retraction of the push rod 35 drives the rack 34 to slide in the cavity block 31. The rack 34 meshes with the gear 33 on the crossbar 21. The sliding of the rack 34 will drive the gear 33 to rotate. The gear 33 is fixed on the crossbar 21. The crossbar 21 is fixed to the rotating shaft 32. The rotating shaft 32 is rotatably installed in the cavity block 31 and its top end is connected to the crossbar 21. Therefore, the rotating rod 37 drives the rotating shaft 32 to rotate, thereby causing the crossbar 21 connected to the rotating shaft 32 to rotate, which in turn drives the foot-operated folding frame 2 to rotate and unfold.

[0029] The positioning unit 4 includes a guide rod 41 that passes through and slides on the crossbar 21. A locking post 42 is fixed to the upper end of the guide rod 41, and a stop bar 43 is fixed to the lower end of the guide rod 41. A tension spring 44 connects the guide rod 41 and the hollow rod 22. During the unfolding of the foot-operated folding frame 2, the guide rod 41 moves along with the crossbar 21 as the crossbar 21 rotates. When the foot-operated folding frame 2 is unfolded to a certain position, the locking post 42 will be subjected to corresponding resistance, the tension spring 44 will be stretched, and the guide rod 41 will slide on the crossbar 21. When the foot-operated folding frame 2 is fully unfolded, the sliding rod 23 can slide along the inner wall of the hollow rod 22 to cooperate with the lower part of the drilling rig to drill into the ground.

[0030] The upper end of the sampling drill 1 is fixed with mating columns 5 on both sides, and the mating columns 5 are provided with arc-shaped grooves. When the foot-operated folding frame 2 is unfolded to both sides of the sampling drill 1, the locking column 42 can slide against the outer arc surface of the mating column 5, thereby pulling the guide rod 41 and the stop rod 43 to move horizontally. When the foot-operated folding frame 2 is unfolded, the locking column 42 slides along the arc-shaped groove on the mating column 5. The arc-shaped groove of the mating column 5 provides a trajectory guide for the sliding of the locking column 42. The sliding of the locking column 42 drives the guide rod 41 to move horizontally, and the guide rod 41 in turn drives the stop rod 43 at the lower end to move horizontally.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the device is initially in its retracted state, with the foot-operated folding frame 2 resting against both sides of the upper end of the sampling drill 1. At this time, the slide rod 23 is partially retracted into the cavity of the hollow rod 22, the footplate 24 is in a higher position, the tension spring 44 is in its natural state, the stop rod 43 is close to the hollow rod 22, and the locking pin 42 is not in contact with the mating pin 5. By rotating the rotating rod 37 on the base block 36, since the rear of the rotating rod 37 is provided with an external thread, and the threaded section is threadedly connected to the push rod 35, the rotating rod 37... Rotation causes push rod 35 to extend and retract along rotating rod 37. Push rod 35 moves forward, driving rack 34 and gear 33 to drive each other. Gear 33 is fixed on cross rod 21. Cross rod 21 is fixed to rotating shaft 32. Rotating shaft 32 is rotatably installed inside cavity block 31 and its top extends to the outside of cavity block 31 and is connected to cross rod 21. Therefore, the rotation of gear 33 drives cross rod 21 to rotate around rotating shaft 32, thereby causing the foot folding frame 2 on both sides of sampling drill 1 to rotate and unfold to both sides.

[0033] When the foot-operated folding frame 2 unfolds to both sides of the sampling drill rig 1, the clamping post 42 slides against the outer arc surface of the mating post 5. As the clamping post 42 slides along the outer arc surface of the mating post 5, it pulls the guide rod 41 to move horizontally. The guide rod 41 passes through and slides on the crossbar 21, and a stop bar 43 is fixed at its lower end. A tension spring 44 is connected between the guide rod 41 and the cavity rod 22. As the guide rod 41 moves, the tension spring 44 is stretched, and the stop bar 43 moves horizontally in sync, disengaging from the state of originally being in contact with the slider 25 on the slide bar 23, thereby making the slide bar 23 in a vertically extendable state.

[0034] After the foot-operated folding frame 2 is unfolded and positioned, the sampling drill 1 can use the support and positioning provided by the foot-operated folding frame 2 to stably carry out sampling work for hydrogeological and environmental geological exploration. The staff can control the overall stability of the drilling rig by stepping on the foot pedal 24, which makes sampling easier. At the same time, the slide rod 23 slides along the inner wall of the cavity rod 22, which can cooperate with the lower part of the drilling rig to drill into the ground.
