Description

Technical Field

[0001] This utility model relates to the field of mine environment soil monitoring technology, specifically an adjustable depth sampler for mine environment soil monitoring. Background Technology

[0002] Mine environmental soil monitoring is a core component in assessing the ecological health of mining areas, and its technological development is directly related to the effectiveness of pollution control and ecological restoration. Currently, mining activities are causing increasingly prominent problems such as heavy metal pollution, acid-base imbalance, and loss of organic matter in the soil.

[0003] Soil sampling is fundamental to soil monitoring in mining environments, providing the material basis for such monitoring. There are many methods for soil sampling, including drilling into the ground using a spiral drill rod. However, this method can cause the upper and lower soil layers to mix, leading to inaccurate sampling, especially when deep sampling is required. Another method involves impacting the sampling tube to insert it into the soil layer and then extracting the sample through the tube. However, this method is not easy to penetrate deep soil layers, especially when the upper soil layer contains debris such as rocks. Therefore, we propose an adjustable-depth sampler for soil monitoring in mining environments to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable depth sampler for monitoring soil in mining environments, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable depth sampler for monitoring soil in a mining environment, comprising a supporting base frame, one end of a guide slide rod fixedly connected to one side of the top of the supporting base frame, the other end of the guide slide rod fixedly connected to one side of the bottom of the supporting top frame, one end of a screw rod fixedly connected to the other side of the bottom of the supporting top frame, and the other end of the screw rod fixedly connected to both sides of the top of the supporting base frame;

[0006] The lead screw and guide slide are respectively slidably sleeved on both sides of the movable plate. The middle part of the movable plate is rotatably sleeved on the top of the hollow spiral rod. The top of the hollow spiral rod is connected to the geared motor. The geared motor is fixedly installed on the movable plate and the side of the geared motor away from the hollow spiral rod is connected to the lead screw nut. The lead screw nut is rotatably connected to the movable plate and the lead screw is connected inside the lead screw nut through a threaded structure.

[0007] The top end of the hollow spiral rod is coaxially connected to a sampling tube via a threaded structure. An operating plate is fixedly connected to both sides of the top end of the sampling tube. A threaded rod is connected to one side of the top end of the hollow spiral rod via a threaded structure. A movable ring is rotatably connected to the bottom end of the threaded rod. The movable ring is slidably sleeved inside the hollow spiral rod. Multiple unfolding components are fixedly connected to the bottom end of the movable ring. A conical arc plate is fixedly connected to the bottom end of each of the multiple unfolding components. The conical arc plate is hinged to the bottom end of the hollow spiral rod.

[0008] Preferably, a support slide rod is fixedly installed on one side inside the hollow spiral rod, and the support slide rod is slidably connected to the movable ring.

[0009] Preferably, multiple conical arc-shaped plates are evenly distributed around the circumference and combined to form a conical structure.

[0010] Preferably, the bottom end of the sampling tube has a serrated structure, and the top end of the threaded rod is fixedly connected to an adjusting cap.

[0011] Preferably, the output shaft of the geared motor is fixedly connected to a drive gear, and a driven gear and an external gear ring are respectively meshed on both sides of the drive gear. The driven gear is fixedly sleeved on the outside of the lead screw nut, and the external gear ring is fixedly sleeved on the top of the hollow screw rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The hollow auger and lead screw nut are driven to rotate by a geared motor. The lead screw nut drives the movable plate to move. At the same time, the rotating hollow auger realizes the drilling operation of the environmental soil. During the movement of the movable plate, the hollow auger continues to drill downward to ensure that the sampling depth can be accurately adjusted.

[0016] 2. The threaded rod, movable ring, unfolding assembly, and conical arc plate are designed to work together. When it is necessary to take individual samples of deep soil, the threaded rod can be rotated by rotating the adjusting cap, causing the movable ring to slide down along the support slide bar. Then, the unfolding assembly pushes the conical arc plate outward, exposing the end of the hollow spiral rod. Individual sampling of deep soil can then be performed by operating the sampling tube, avoiding the problem of not being able to take deep samples due to the influence of upper stones and other debris.

[0017] 3. The bottom of the sampling tube is designed with a serrated structure, which makes it easier to cut into the soil, reduce sampling resistance, and improve sampling efficiency;

[0018] 4. The mounting blocks and fixing nails on the support base frame can firmly fix the equipment on the mining ground, preventing the sampling accuracy from being affected by the shaking of the equipment during the sampling process, and ensuring the stability and reliability of the entire sampling process.

[0019] 5. The geared motor is connected to the driven gear and the external gear ring through the meshing of the driving gear, realizing independent drive control of the lead screw nut and the hollow screw rod. It has a compact structure and high transmission efficiency. Attached Figure Description

[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] Example 1

[0027] Reference Figure 1 , 2This is the first embodiment of the present invention. This embodiment provides an adjustable depth sampler for monitoring soil in a mining environment, including a supporting base frame 1. One end of a guide slide rod 7 is fixedly connected to one side of the top of the supporting base frame 1. The other end of the guide slide rod 7 is fixedly connected to one side of the bottom of the supporting top frame 6. One end of a screw rod 4 is fixedly connected to the other side of the bottom of the supporting top frame 6. The other end of the screw rod 4 is fixedly connected to both sides of the top of the supporting base frame 1.

[0028] The lead screw 4 and the guide slide rod 7 are respectively slidably sleeved on both sides of the movable plate 8. The middle part of the movable plate 8 is rotatably sleeved on the top of the hollow spiral rod 9. The top of the hollow spiral rod 9 is connected to the geared motor 10. The geared motor 10 is fixedly installed on the movable plate 8, and the side of the geared motor 10 away from the hollow spiral rod 9 is connected to the lead screw nut 5. The lead screw nut 5 is rotatably connected to the movable plate 8, and the lead screw 4 is connected inside the lead screw nut 5 through a threaded structure.

[0029] The top end of the hollow spiral rod 9 is coaxially connected to the sampling tube 11 via a threaded structure. The top two sides of the sampling tube 11 are respectively fixedly connected to the operating plate 12. The top one side of the hollow spiral rod 9 is connected to the threaded rod 14 via a threaded structure. The bottom end of the threaded rod 14 is rotatably connected to the movable ring 15. The movable ring 15 is slidably sleeved inside the hollow spiral rod 9. The bottom end of the movable ring 15 is fixedly connected to multiple unfolding components 17. The bottom ends of the multiple unfolding components 17 are respectively fixedly connected to the conical arc plate 18. The conical arc plate 18 is respectively hinged to the bottom end of the hollow spiral rod 9.

[0030] Example 2

[0031] Reference Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, a support slide rod 16 is fixedly installed on one side inside the hollow spiral rod 9. The support slide rod 16 is slidably connected to the movable ring 15. The setting of the support slide rod 16 enables the movable ring 15 to move linearly inside the hollow spiral rod 9.

[0032] Specifically, multiple conical arc plates 18 are evenly distributed around the circumference and combined to form a conical structure. This conical structure helps to form a stable support surface when unfolded, ensuring the stability and accuracy of deep soil sampling. When unfolded, the end opening of the hollow spiral rod 9 is exposed, avoiding obstruction of the sampling operation of the sampling tube 11. At the same time, in the unfurled state, the conical arc plates 18 are tightly fitted to form a conical structure, located at the bottom end of the hollow spiral rod 9, and will not affect the normal drilling of the hollow spiral rod 9.

[0033] Specifically, the bottom end of the sampling tube 11 has a serrated structure. This design can reduce the resistance when the sampling tube 11 cuts into the soil, making the sampling process easier and more efficient. Especially in hard soil or soil containing stones, the serrated structure can cut into and bring out soil samples better. The top end of the threaded rod 14 is fixedly connected to an adjusting cap 13, and the threaded rod 14 can be rotated by operating the adjusting cap 13.

[0034] Specifically, the output shaft of the geared motor 10 is fixedly connected to a drive gear 101. The two sides of the drive gear 101 are respectively meshed with a driven gear 51 and an external gear ring 91. The driven gear 51 is fixedly sleeved on the outside of the lead screw nut 5, and the external gear ring 91 is fixedly sleeved on the top of the hollow screw rod 9.

[0035] Specifically, multiple evenly distributed mounting blocks 2 are fixedly connected to the outer perimeter of the supporting base frame 1. The bottom end of the mounting block 2 is fixedly connected to a fixing nail 3. The fixing nail 3 is inserted into the soil of the mining environment to be sampled to securely fix the equipment.

[0036] Specifically, the unfolding assembly 17 includes a movable seat 171, a connecting rod 172, and a transmission seat 173. The movable seat 171 is fixedly connected to the bottom end of the movable ring 15. The movable seat 171 is hinged to one end of the connecting rod 172, and the other end of the connecting rod 172 is hinged to the transmission seat 173. The transmission seat 173 is fixedly connected to the inner wall of the conical arc plate 18.

[0037] The working principle and process are as follows: The fixing nail 3 is inserted into the soil of the mining environment to be sampled, securing the equipment firmly. The geared motor 10, powered by an external power supply, drives the drive gear 101 to rotate. The drive gear 101 drives the driven gear 51 and the external gear ring 91. The driven gear 51 drives the screw nut 5 to rotate on the movable plate 8. Since the screw nut 5 and the screw 4 are connected by a threaded structure and the screw 4 is fixed, the rotation of the screw nut 5 causes the movable plate 8 to move downwards along the screw 4 and the guide slide 7. Simultaneously, the external gear ring 91 drives the hollow spiral rod 9 to rotate. During rotation, the hollow spiral rod 9 gradually drills into the soil. As the movable plate 8 moves, the hollow spiral rod 9 continues to drill downwards, achieving precise control at different depths. When it is necessary to target deep soil layers... During individual sampling, rotating the adjusting cap 13 causes the threaded rod 14 to rotate. The movable ring 15 at the bottom of the threaded rod 14 slides downward along the support slide rod 16. The movable ring 15 pushes the conical arc plate 18 outward through the unfolding assembly 17 (movable seat 171, connecting rod 172, transmission seat 173), exposing the end of the hollow spiral rod 9. At this time, the operating plate 12 can be manually operated to rotate the sampling tube 11. While rotating, the sampling tube 11 moves into the soil through the threaded structure. With the serrated structure at the end of the sampling tube 11, it cuts into the soil more easily, reducing sampling resistance and improving sampling efficiency. The sampling tube 11 allows for individual sampling of deep soil, avoiding the influence of upper debris. After sampling, the above steps are reversed to remove the equipment from the soil and remove the sampling tube 11 to obtain the required soil sample.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
