Description

Technical Field

[0001] This utility model belongs to the field of geological drilling technology, and in particular relates to an in-situ rapid sampler for geological drilling. Background Technology

[0002] As my country's geological exploration work extends to more complex terrains and the demand for timely geological information acquisition in mineral resource development continues to increase, it is now necessary not only to ensure that the original structure of soil or rock samples is not damaged during the sampling process and to guarantee the representativeness of the samples, but also to ensure that the equipment has good portability so that it can be moved and operated flexibly in complex terrains, while also enabling rapid sampling and shortening the exploration cycle.

[0003] A Chinese patent application with publication number CN218444529U discloses a coal mine geological drilling sampler, which is a relatively close prior art solution. This sampler includes a motor, a drill bit, and a housing. The drill bit is fixedly connected to the output end of the motor. Two fixing blocks are located on the side of the housing near the motor and are fixedly connected to it. A threaded rod is provided between the fixing blocks, and a matching nut seat is provided on the threaded rod. The nut seat is fixed to the motor by bolts. Four casters are provided at the lower end of the housing. A stabilizing component is located inside the housing to stabilize it, and the stabilizing component is linked to the casters. This technical solution aims to facilitate the movement of the equipment through the casters and ensure the stability of the housing during sampling through the stabilizing component, thereby facilitating drilling and sampling at different locations and improving work efficiency.

[0004] Existing sampling equipment meets some sampling needs to a certain extent. However, the overall size and weight of existing sampling devices are relatively large. In mountainous and hilly areas without flat roads, the equipment still needs to be transported by vehicle or carried by multiple people, resulting in poor operational flexibility and failing to meet the needs of rapid sampling in complex terrain. While traditional manual samplers are portable, their sampling efficiency is extremely low and cannot be adapted to large-scale exploration operations. The soil sampling tubes of traditional samplers are mostly of fixed length, which cannot flexibly adjust the sampling depth according to actual exploration needs. If samples from deeper strata are required, soil sampling tubes of different lengths need to be replaced, which is cumbersome and increases the cost of carrying the equipment. At the same time, some samplers lack an effective sealing and protection structure at the bottom of the soil sampling tube. During the process of removing the soil sampling tube from the ground after sampling, the soil sample is easily dropped due to vibration or gravity, resulting in sample loss and affecting the accuracy of subsequent geological analysis.

[0005] To address these issues, we provide an in-situ rapid sampler for geological drilling. Utility Model Content

[0006] The purpose of this invention is to provide an in-situ rapid sampler for geological drilling. By combining the rotating component and the first soil sampling tube, it solves the problems of insufficient portability and terrain adaptability of existing equipment, as well as the lack of an effective sealing and protection structure that leads to easy sample loss.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to an in-situ rapid sampler for geological drilling, comprising a first sampling tube, a rotating assembly at the top of the first sampling tube, and a carrying assembly on one side of the rotating assembly. The rotating assembly includes a housing, the bottom of which is located at the top of the first sampling tube. A motor (BLDC-40-24-3000) is fixedly connected to the top of the housing's inner cavity. A first pulley is fixedly connected to the motor's output end, and a second pulley is connected to one side of the first pulley via a belt. A connecting rod is fixedly connected to the bottom of the second pulley, extending through to the bottom of the housing and fixedly connected to the first sampling tube. The housing adopts a rectangular hollow sealed structure, and a fastening screw is used at the center of the top of the housing's inner cavity. The motor is fixedly installed on the bolt. The first pulley, belt, and second pulley form a smooth transmission structure. The bottom of the second pulley is coaxially fixed to the top of the connecting rod through a flexible coupling. The connecting rod adopts a solid stepped shaft structure, with a sealed bearing fitted in the middle that matches the opening at the bottom of the housing. The outer ring of the bearing is welded to the housing, and the inner ring is interference-fitted with the connecting rod. The flexible coupling can buffer the instantaneous torque impact when the motor starts, preventing the connecting rod from bending due to uneven force. The sealed bearing ensures smooth rotation of the connecting rod and further enhances the sealing performance of the housing. The bottom of the connecting rod has an integrally formed annular flange with four bolt holes evenly spaced on it. These bolts are fastened to the flange pre-set at the top of the first soil sampling pipe using high-strength bolts.

[0009] The present invention is further configured such that the carrying assembly includes a fixing plate, the fixing plates being equidistantly arranged, one side of the fixing plate being fixedly connected to the housing, and one side of the fixing plate being movably connected to a first connecting plate via a pivot. A carrying strap is fixedly connected to the bottom of the first connecting plate. The equidistantly arranged fixing plates are firmly connected to the housing, so that the carrying assembly is evenly distributed with force, avoiding local stress concentration that could cause the components to loosen during outdoor carrying. The fixing plate and the first connecting plate are movably connected via a pivot, allowing the carrying strap to rotate flexibly around the pivot to adapt to different usage needs. The bottom of the first connecting plate is fixed to the carrying strap, so that the adjustment of the rotation angle is directly transmitted to the carrying strap, ensuring that the equipment fits more closely to the back of the user during carrying, reducing the shaking amplitude of the equipment when moving on rugged terrain in the wild, reducing the physical exertion of the operator, and improving the comfort of long-distance carrying.

[0010] The present invention is further configured such that a second soil sampling tube is fitted at the bottom of the inner cavity of the first soil sampling tube, and a fixing tube is fitted on the surface of the second soil sampling tube. The top of the fixing tube is threadedly connected to the bottom of the first soil sampling tube, and a cover plate is provided at the bottom of the second soil sampling tube. The second soil sampling tube can be replaced with a second soil sampling tube of different lengths according to the actual sampling depth requirements of geological drilling, which greatly reduces the equipment carrying cost and transportation burden. The threaded connection between the top of the fixing tube and the bottom of the first soil sampling tube enables quick disassembly and assembly of the second soil sampling tube, simplifies the operation process, and improves the efficiency of field operations. The cover plate can be closed after sampling, effectively preventing soil samples from falling due to vibration, bumps, or gravity during field movement, ensuring sample integrity, and providing the original sample basis for subsequent geological component analysis.

[0011] The present invention is further configured such that a fixing strap is fixedly connected to one side of the carrying strap, a clamping plate is fixedly connected to one side of the fixing strap, and a second connecting plate is provided on one side of the clamping plate. The fixing strap provides a stable mounting carrier for the clamping plate, preventing the clamping plate from falling off due to frequent carrying in the field. The two clamping tongues form a symmetrical locking structure, and the force is balanced when they cooperate with the clamping plate, preventing the locking from loosening when carrying in the field.

[0012] The present invention is further configured such that a latch is fixedly connected to one side of the second connecting plate, and there are two latches. A first anti-slip texture is provided on one side of the latch. The first anti-slip texture on one side of the latch can increase the static friction between the latch and the plate. Even if the operator's hands are covered with mud or he is wearing gloves, it can ensure that the latch is not easy to slip after it is engaged. At the same time, when moving in the field, the anti-slip texture can prevent the latch and the plate from shifting relative to each other, maintain the fit between the equipment and the human body, and improve the carrying safety.

[0013] The present invention is further configured such that a handle is fixedly connected to the top of the box, and the surface of the handle is provided with a second anti-slip texture. The handle provides a convenient force application point for the equipment. When adjusting the position of the equipment by moving it over short distances in the field, the user can directly hold the handle to move it, which greatly improves the flexibility of operation.

[0014] The present invention is further provided that a maintenance plate is provided on one side of the housing. The maintenance plate is fixedly connected to the housing by bolts. The maintenance plate provides a convenient maintenance channel for the motor and connecting rod. When the equipment fails in the field, it can be opened for maintenance only by removing the bolts fixing the maintenance plate, which greatly shortens the maintenance time.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses a fixed plate to be fixedly connected to the box body, and a first connecting plate to be movably connected to the fixed plate via a rotating shaft, so that the carrying strap can adapt to different carrying postures according to the needs of the operator. The cooperation between the latch and the plate can achieve a close fit to the operator's body and prevent shaking during carrying. In addition, when the operator moves the equipment over a short distance or adjusts the position of the equipment in a narrow space, the equipment can be easily moved by the handle, further improving the operational flexibility of the equipment.

[0017] 2. This utility model allows for flexible adjustment of sampling depth by selecting second soil sampling tubes of different lengths according to actual exploration needs, thereby reducing equipment carrying costs and operational complexity. At the same time, the cover plate at the bottom of the second soil sampling tube can prevent soil samples from falling off due to vibration or gravity during the sampling process after sampling is completed, ensuring the integrity of the samples and providing an accurate sample basis for subsequent geological analysis.

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-6 This utility model is an in-situ rapid sampler for geological drilling, including a first soil sampling tube 1, a rotating component 2 at the top of the first soil sampling tube 1, a carrying component 3 on one side of the rotating component 2, the rotating component 2 including a housing 21, the bottom of the housing 21 being located at the top of the first soil sampling tube 1, a motor 22 fixedly connected to the top of the inner cavity of the housing 21, a first pulley 23 fixedly connected to the output end of the motor 22, a second pulley 24 connected to one side of the first pulley 23 via a belt, a connecting rod 25 fixedly connected to the bottom of the second pulley 24, the bottom of the connecting rod 25 penetrating to the bottom of the housing 21 and fixedly connected to the first soil sampling tube 1.

[0028] Specifically: The housing 21 adopts a rectangular hollow sealed structure. The motor 22 is fixedly installed in the center of the top of the inner cavity of the housing 21 by fastening bolts. The motor 22 is a BLDC-40-24-3000. The first pulley 23, the belt and the second pulley 24 form a transmission structure with smooth transmission. The bottom of the second pulley 24 is coaxially fixed to the top of the connecting rod 25 by an elastic coupling. The connecting rod 25 adopts a solid stepped shaft structure. A sealed bearing adapted to the opening at the bottom of the housing 21 is sleeved in the middle. The outer ring of the bearing is welded to the housing 21 and the inner ring is interference-fitted with the connecting rod 25. The elastic coupling can buffer the instantaneous torque impact when the motor 22 starts and prevent the connecting rod 25 from bending due to uneven force. The sealed bearing not only ensures the smooth rotation of the connecting rod 25, but also further enhances the sealing performance of the housing 21. The bottom of the connecting rod 25 has an integrally formed annular flange with four bolt holes evenly opened on the flange. It is fastened to the flange pre-set at the top of the first soil sampling pipe 1 by high-strength bolts.

[0029] The carrying assembly 3 includes a fixing plate 31, which is equidistant from each other. One side of the fixing plate 31 is fixedly connected to the housing 21. A first connecting plate 32 is movably connected to one side of the fixing plate 31 via a pivot. A carrying strap 33 is fixedly connected to the bottom of the first connecting plate 32. A second soil sampling tube 4 is fitted into the bottom of the inner cavity of the first soil sampling tube 1. A fixing tube 5 is fitted onto the surface of the second soil sampling tube 4. The top of the fixing tube 5 is threadedly connected to the bottom of the first soil sampling tube 1. A cover plate 6 is provided at the bottom of the second soil sampling tube 4. A fixing strap 7 is fixedly connected to one side of the carrying strap 33. A clamping plate 8 is fixedly connected to one side of the fixing strap 7. A second connecting plate 9 is provided on one side of the clamping plate 8. A latch 10 is fixedly connected to one side of the second connecting plate 9. There are two latches 10. A first anti-slip texture is provided on one side of the latch 10. A handle 11 is fixedly connected to the top of the housing 21. A second anti-slip texture is provided on the surface of the handle 11. An inspection plate 12 is provided on one side of the housing 21. The inspection plate 12 is fixedly connected to the housing 21 by bolts.

[0030] Specifically: the equidistant fixing plates 31 are firmly connected to the housing 21, ensuring even distribution of force on the carrying assembly 3 and preventing localized stress concentration that could cause loosening of components during field carrying. The fixing plates 31 and the first connecting plate 32 are movably connected via a pivot, allowing the carrying strap 33 to rotate flexibly around the pivot to adapt to different usage needs. The bottom of the first connecting plate 32 is fixed to the carrying strap 33, ensuring that the adjustment of the rotation angle is directly transmitted to the carrying strap 33, guaranteeing a closer fit between the equipment and the user's back during carrying, reducing the shaking amplitude of the equipment when moving on rugged terrain, reducing the physical exertion of the operator, and improving the comfort of long-distance carrying. The second soil sampling pipe 4 can be replaced with different lengths according to the actual sampling depth requirements of geological drilling, significantly reducing the cost of carrying the equipment and the burden of transportation. The top of the fixing pipe 5 is threaded to the bottom of the first soil sampling pipe 1, enabling quick assembly and disassembly of the second soil sampling pipe 4, simplifying the operation process and improving the efficiency of field operations. The cover plate 6 can be closed after sampling, effectively preventing soil from being shaken, bumped, or affected by gravity during field movement. Soil samples are prevented from falling off, ensuring sample integrity and providing a raw sample basis for subsequent geological composition analysis. The fixing strap 7 provides a stable mounting carrier for the clamping plate 8, preventing it from falling off due to frequent field transport. The two latches 10 form a symmetrical locking structure, ensuring balanced force distribution when engaged with the clamping plate 8, preventing loosening during field transport. The first anti-slip groove on one side of the latch 10 increases the static friction between the latch 10 and the clamping plate 8, ensuring that even if the operator's hands are covered in mud or they are wearing gloves, the clamping will not easily slip, and it will withstand bumpy field conditions. When the device is moved, the anti-slip texture prevents the latch 10 and the clamp plate 8 from shifting relative to each other, maintaining the fit between the device and the human body and improving carrying safety. The handle 11 provides a convenient point of force application for the device. When adjusting the position of the device by moving it over short distances in the field, the handle 11 can be directly grasped for transport, greatly improving operational flexibility. The maintenance plate 12 provides a convenient maintenance channel for the motor 22 and the connecting rod 25. When the device malfunctions in the field, it can be opened for maintenance simply by removing the bolts that fix the maintenance plate 12, greatly shortening maintenance time.

[0031] The working principle of this utility model is as follows: Before sampling, a second soil sampling tube 4 of corresponding length is selected according to the target depth requirements of geological drilling. The second soil sampling tube 4 is inserted into the bottom of the inner cavity of the first soil sampling tube 1. Then, the top of the fixing tube 5 is aligned with the threaded interface at the bottom of the first soil sampling tube 1 and tightened. The second soil sampling tube 4 is quickly fixed through the threaded connection. At this time, the cover plate 6 is in the open state, which facilitates the entry of soil samples. The operator carries the equipment to the sampling point through the carrying assembly 3. When carrying the equipment, the latch 10 is inserted into the clamping plate 8 to ensure that the carrying strap 33 fits tightly with the body, reducing the shaking of the equipment during movement. When moving short distances or adjusting in narrow areas, the handle 11 is directly held to carry the equipment, improving the convenience of operation. After arriving at the sampling point, the second soil sampling tube 4 is aligned with the sampling position, and the motor 22 is started. The machine 22 drives the first pulley 23 and the second pulley 24 to rotate in sequence. The second pulley 24 drives the connecting rod 25 with a solid stepped shaft structure to rotate through an elastic coupling. The elastic coupling effectively buffers the instantaneous torque impact when the motor 22 starts, preventing the connecting rod 25 from bending. The sealed bearing in the middle of the connecting rod 25 not only ensures the smooth rotation of the connecting rod 25, but also prevents soil and rainwater from entering the housing 21, achieving sealing protection. The connecting rod 25 is connected to the top flange of the first soil sampling pipe 1 by high-strength bolts through the bottom annular flange, accurately transmitting the rotational power to the first soil sampling pipe 1 and the second soil sampling pipe 4, driving them to rotate synchronously and drill to complete the in-situ collection of soil samples. Then, the cover plate 6 is installed at the bottom of the second soil sampling pipe 4 to prevent the samples from falling due to vibration and bumps when moving in the field.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
