[0001] The utility model relates to the technical field of samplers, in particular to a portable geological prospecting sampler. Background Art

[0002] In the field of geological exploration, sampling machines are indispensable and important tools used to obtain samples from underground or rocks for analysis.

[0003] The Chinese utility model patent with publication number CN211877407U discloses a portable geological exploration sampler. In this technology, a fixed block is movably connected to a fixed column, and a first groove and a second groove at the left end of the fixed block are spirally connected with a bolt, so that the sampler can be easily moved up and down, and it is simple and convenient to use. However, after sampling using the sampler, it is usually necessary to manually rotate the drill rod off the equipment before taking out the soil sample inside the drill rod for subsequent survey and analysis. This method is inefficient and inconvenient to operate.

[0004] Therefore, a portable geological exploration sampling machine with convenient use and high efficiency is needed to solve the above problems. Utility Model Content

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable geological exploration sampling machine, comprising a base, moving wheels symmetrically fixedly arranged on one side of the base, a bracket fixedly arranged on the base at a position above one side close to the moving wheels, a through hole opened on the side of the base corresponding to the bracket, a driving mechanism arranged on the bracket, and a sampling barrel screwed on the driving mechanism and located above the through hole; the design of the base and the moving wheels allows the user to easily move and transport the sampler between different geological exploration points, and the design of the driving mechanism enables the sampling barrel to accurately control its rotation and feed speed, thereby ensuring the accuracy and efficiency of sampling.

[0009] In order to further improve the convenience and efficiency of sampling, unlike the existing samplers, the sampler also includes a rotating disk rotatably connected to the through hole, a sampling hole provided on the rotating disk for the sampling tube to pass through for sampling, a clamping mechanism arranged on the rotating disk for clamping the sampling tube, and a rotating mechanism arranged on the base for driving the rotating disk to rotate; the combined design of the rotating disk, the clamping mechanism and the rotating mechanism, after each sampling operation is completed, the sampling tube can be clamped by the clamping mechanism, and then the rotating disk is driven by the rotating mechanism, which can automatically rotate the sampling tube from the driving mechanism after sampling, without manual rotation, thereby improving the convenience and efficiency of sampling.

[0010] Preferably, in order to facilitate sampling using the sampling barrel, the driving mechanism includes a sprocket symmetrically connected to the bracket on the side close to the sampling barrel, a transmission chain arranged between the two sprockets, a first servo motor fixedly arranged on one side of the bracket for driving one of the sprockets to rotate, a slider slidably sleeved on the bracket and fixedly connected to the transmission chain on the side close to the sampling barrel, a connecting seat fixedly connected to the slider on the side away from the bracket, a rotating shaft rotatably connected to the slider, and a second servo motor fixedly installed on the top of the connecting seat for driving the rotating shaft to rotate, the bottom of the rotating shaft is threadedly connected to the sampling barrel, and the two sprockets are connected and transmit power through the transmission chain; by using the precise control of the first servo motor and the second servo motor, precise rotation and feeding operations of the sampling barrel can be achieved, which helps to accurately obtain the required geological samples under complex geological conditions and meet the accuracy requirements of exploration.

[0011] Preferably, in order to further improve the convenience of movement of the sampler, a handle is fixedly installed on the side of the bracket away from the first servo motor; the design of the handle allows the operator to hold and move the entire sampler more conveniently, thereby improving the flexibility and efficiency of the exploration work.

[0012] Preferably, in order to facilitate the clamping of the sampling tube, the clamping mechanism includes clamping blocks symmetrically arranged on the rotating disk at positions corresponding to both sides of the sampling hole and movable closer or farther away, a mounting plate arranged on the side away from each other of the two clamping blocks and fixedly connected to the rotating disk, a servo electric cylinder fixedly mounted on the mounting plate on a side close to the clamping block and connected to the clamping block, and a telescopic rod arranged on the outside of the servo electric cylinder and fixedly connected at both ends to the clamping block and the mounting plate respectively; the clamping block can be driven by the servo electric cylinder to accurately move closer to or farther away from the sampling tube, thereby achieving accurate clamping of the sampling tube.

[0013] Preferably, in order to improve the stability of clamping, a rubber pad in contact with the sampling barrel is fixedly installed on one side of the two clamping blocks close to each other; the design of the rubber pad can enhance the friction between the clamping block and the sampling barrel, ensuring that the sampling barrel is stably clamped during the sampling process to prevent it from sliding or deflecting.

[0014] Preferably, in order to facilitate the automatic rotation of the sampling tube after clamping, the rotating mechanism includes a gear ring fixedly mounted on the rotating disk and located in the base, a gear rotatably connected in the base and meshing with the gear ring, and a third servo motor fixedly mounted on the base for driving the gear to rotate; the combined design of the gear and the gear ring can efficiently transmit the power of the third servo motor to the rotating disk, ensuring that the sampling tube can rotate quickly and stably.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides a portable geological exploration sampling machine, such as Figure 1-Figure 3 As shown, the sampler includes a base 1, a moving wheel 12 symmetrically fixedly arranged on one side of the base 1, a bracket 2 fixedly arranged at a position above one side of the base 1 close to the moving wheel 12, a through hole 11 opened on the side of the base 1 corresponding to the bracket 2, a driving mechanism 4 arranged on the bracket 2, and a sampling barrel 3 screwed on the driving mechanism 4 and located above the through hole 11; the sampler also includes a rotating disk 5 rotatably connected to the through hole 11, a sampling hole 51 opened on the rotating disk 5 for the sampling barrel 3 to pass through for sampling, a clamping mechanism 6 arranged on the rotating disk 5 for clamping the sampling barrel 3, and a rotating mechanism 7 arranged on the base 1 for driving the rotating disk 5 to rotate.

[0030] During use, through the design of the moving wheels 12, the operator can tilt and push the entire sampler so that the two moving wheels 12 are in contact with the ground, and can move the sampler to the position that needs to be surveyed, then place the base 1 flat on the surveyed ground, and then start the driving mechanism 4 to drive the sampling tube 3, so that the sampling tube 3 rotates and descends and passes through the sampling hole 51 to take soil samples. After the sampling is completed, the driving mechanism 4 is started again to drive the sampling tube 3 to rotate and rise to a position above the sampling hole 51. After that, the driving mechanism 4 is paused, and the clamping mechanism 6 is started to clamp and fix the sampling tube 3 after sampling, and then the rotating mechanism 7 is started to drive the rotating disk 5 to rotate. Since the sampling tube 3 is screwed to the driving mechanism 4, as the rotating disk 5 rotates, the sampling tube 3 clamped by the clamping mechanism 6 can automatically disengage from the connection with the driving mechanism 4, so that the sampling tube 3 can be easily removed from the driving mechanism 4 without manual rotation.

[0031] Specifically, the driving mechanism 4 includes a sprocket 41 symmetrically connected to the side of the bracket 2 close to the sampling tube 3, a transmission chain 42 arranged between the two sprockets 41, a first servo motor 43 fixedly arranged on one side of the bracket 2 for driving one of the sprockets 41 to rotate, a slider 44 slidably sleeved on the bracket 2 and fixedly connected to the side of the transmission chain 42 close to the sampling tube 3, a connecting seat 45 fixedly connected to the slider 44 away from the bracket 2, a rotating shaft 46 rotatably connected to the slider 44, and a second servo motor 47 fixedly installed on the top of the connecting seat 45 for driving the rotating shaft 46 to rotate, the bottom of the rotating shaft 46 is screwed to the sampling tube 3, and the two sprockets 41 are connected and transmit power through the transmission chain 42; when the entire sampling machine is moved to the survey point, the first servo motor 43 is started to drive the sprocket connected thereto 41 rotates. Since the two sprockets 41 are connected and transmit power through the transmission chain 42, and the slider 44 is fixedly connected to the transmission chain 42, when one of the sprockets 41 rotates, the slider 44 can slide on the bracket 2. Since the slider 44 is connected to the rotating shaft 46 through the connecting seat 45, and the sampling tube 3 is screwed to the rotating shaft 46, the sampling tube 3 can be lowered and pass through the sampling hole 51 by adjusting the position of the slider 44. Then, the second servo motor 47 is started to drive the rotating shaft 46 to rotate, and the sampling tube 3 can rotate the soil located at the sampling hole 51 and feed it into the sampling tube 3. After the sampling in the sampling tube 3 is completed, the second servo motor 47 can be paused, and then the first servo motor 43 can be started, so that the slider 44 drives the slider 44 after sampling to move up to the position above the sampling hole 51.

[0032] In order to further improve the convenience of moving the sampler, a handle 48 is fixedly installed on the side of the bracket 2 away from the first servo motor 43; through the cooperation of the moving wheel 12, the design of the handle 48 allows the operator to more conveniently hold and move the entire sampler, thereby improving the flexibility and efficiency of the exploration work.

[0033] Furthermore, the clamping mechanism 6 includes clamping blocks 61 symmetrically arranged at positions on both sides of the corresponding sampling holes 51 on the rotating disk 5 and movable closer or farther away, a mounting plate 62 arranged on the side away from each other of the two clamping blocks 61 and fixedly connected to the rotating disk 5, a servo electric cylinder 63 fixedly installed on the side of the mounting plate 62 close to the clamping block 61 and connected to the clamping block 61, and a telescopic rod 64 arranged on the outside of the servo electric cylinder 63 and fixedly connected to the clamping block 61 and the mounting plate 62 at both ends; when the soil sampling is completed in the sampling tube 3, the two servo electric cylinders 63 can be started, and at this time, the corresponding servo electric cylinders Under the telescopic guiding action of the telescopic rod 64 on one side of 63, the two clamping blocks 61 can stably move close to and contact the sampling tube 3. Under the continued driving action of the two servo electric cylinders 63, the two clamping blocks 61 can clamp and fix the two sides of the sampling tube 3. After the rotating disk 5 is driven by the rotating mechanism 7 to drive the clamped sampling tube 3 to rotate down from the rotating shaft 46, the operator manually holds the sampling tube 3, and then starts the two servo electric cylinders 63 to drive the two clamping blocks 61 to move away, so as to release the clamping of the rotating sampling tube 3, so that the operator can take out the soil from the sampling tube 3 for survey.

[0034] In addition, in order to improve the stability of clamping, rubber pads in contact with the sampling tube 3 are fixedly installed on the sides of the two clamping blocks 61 that are close to each other; the design of the rubber pads can enhance the friction between the clamping blocks 61 and the sampling tube 3, ensuring that the sampling tube 3 is stably clamped during the sampling process to prevent it from sliding or deflecting.

[0035] Furthermore, the rotating mechanism 7 includes a gear ring 71 fixedly mounted on the rotating disk 5 and located in the base 1, a gear 72 rotatably connected to the base 1 and meshing with the gear ring 71, and a third servo motor 73 fixedly mounted on the base 1 for driving the gear 72 to rotate; after the two clamping blocks 61 are driven to clamp and fix the sampling tube 3, the third servo motor 73 can be started to drive the gear 72 connected thereto to rotate. Since the gear 72 is meshed with the gear ring 71 on the rotating disk 5, when the driving gear 72 rotates, the rotating disk 5 can synchronously drive the sampling tube 3 clamped by the two clamping blocks 61 to rotate. At this time, the sampling tube 3 can be loosened at the threaded connection of the rotating shaft 46, and then the sampling tube 3 can be automatically removed from the rotating shaft 46. When the connection between the sampling tube 3 and the rotating shaft 46 is loosened, the third servo motor 73 can be paused.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
