[0020] This utility model provides an electric sampler for soil environmental testing, such as... Figures 1-4 As shown, the electric sampler for soil environmental testing includes: a base 1; two slide rods 6, both of which are detachably mounted on the top of the base 1; two sliders 7, each movably mounted on one of the slide rods 6; a gear box 8, fixed between the two sliders 7, containing two meshing gears; a motor 10, fixed to the gear box 8, with its output shaft connected to either of the gears; a threaded rod 11, rotatably mounted on the gear box 8, connected to the other gear; and a two-part drill bit 12, mounted at the bottom of the threaded rod 11, used for drilling soil samples.
[0021] In this embodiment, the base 1 serves as the supporting foundation of the entire sampler, ensuring stability during sampling and providing a stable mounting platform for other components. The design of the slide rod 6 allows the sampler to be adjusted in height in the vertical direction, while the detachable feature facilitates transportation and storage, reducing the overall volume and weight. The free sliding of the slider 7 on the slide rod 6, combined with the subsequent transmission mechanism, achieves precise feeding of the sampler in the soil, ensuring the accuracy of the sampling depth. The design of the gear box 8 cleverly converts the rotary motion of the motor 10 into the motion of the threaded rod 11, achieving lift control of the sampling drill bit. The motor 10 serves as the power source for the entire sampler, driving the sampling process. Through the cooperation of the motor 10 and the gear transmission, the two-part drill bit 12 can be rotated, thereby drilling and sampling the ground. The two-part drill bit 12 is inserted into the ground through the gravity of the slider 7 and the gear box 8.
[0022] In further preferred embodiments of the present application, the two-part drill bit 12 is composed of a first cylinder plate and a second cylinder plate. The first cylinder plate is fixed to the bottom of the threaded rod 11, and the second cylinder plate is hinged to the first cylinder plate. A metal snap ring is movably sleeved outside the first cylinder plate and the second cylinder plate, and the two ends of the metal snap ring are connected by bolts.
[0023] In this embodiment, the first cylinder plate serves as the main fixed part of the two-part drill bit 12, and it is directly fixed to the bottom of the threaded rod 11. This design ensures the stability and guidance of the drill bit during sampling, allowing the drill bit to penetrate the soil according to the predetermined path. The second cylinder plate is connected to the first cylinder plate through a hinged connection. This hinged design allows the second cylinder plate to swing or open and close relative to the first cylinder plate within a certain range during sampling, thereby adapting to different hardness and structure of the soil. The metal snap ring serves to tightly close the two-part drill bit 12 before sampling, forming a whole drill bit structure to enhance the rigidity and penetration of the drill bit. After sampling is completed, the two-part drill bit 12 can be easily opened by loosening the bolts and adjusting the position of the metal snap ring, releasing the soil sample and avoiding the problem of difficult sampling with traditional drill bits.
[0024] In further preferred embodiments of the present application, two auxiliary walking wheels 13 are rotatably installed on both sides of the base 1. Anti-skid sleeves are fixedly sleeved outside the plurality of auxiliary walking wheels 13. The top of the base 1 is provided with two folding legs for stabilizing the base 1.
[0025] In the embodiment, the auxiliary walking wheels 13 not only provide the sampler with the moving ability, but also enable the sampler to be more easily moved and positioned under different terrains and soil conditions, and each auxiliary walking wheel 13 is fixedly sleeved with an anti-skid sleeve, which increases the friction between the walking wheel and the ground, prevents the sampler from being unstable due to sliding or tilting during sampling, and improves the safety of the sampling operation.
[0026] In the further preferred embodiment of the utility model, the folding support leg is composed of a support rod 2, an adjusting rod 3, a limiting plate 4 and a plurality of fixing cones 5, the support rod 2 is fixed on the top of the base 1, the adjusting rod 3 is hinged on the support rod 2, the limiting plate 4 is hinged on the adjusting rod 3, the limiting plate 4 can be in contact with the ground, and the plurality of fixing cones 5 are all installed on the bottom of the limiting plate 4 and can be inserted into the ground.
[0027] In the embodiment, the support rod 2 serves as the main supporting part of the folding support leg, the support rod 2 is fixed on the top of the base 1, the adjusting rod 3 is connected with the support rod 2 through hinging, and is allowed to rotate or adjust within a certain range, which enables the folding support leg to adjust the length and angle according to actual needs, so as to adapt to different ground conditions and provide more stable support, the limiting plate 4 is designed to increase the contact area of the support leg with the ground and provide a stable support platform, and the fixing cones 5 play a key role during sampling, which can penetrate into the soil and increase the friction between the support leg and the ground, so as to further improve the stability of the sampler, especially on soft or uneven ground, the fixing cones 5 play a more obvious role, which can effectively prevent the sampler from being displaced or tilted due to external force.
[0028] In the further preferred embodiment of the utility model, the base 1 is provided with openings allowing the two halves of the drill bit 12, and the top of the base 1 is slidably provided with two sliding plates 14, each of which is provided with a support frame 15 on the side close to the other, and a plurality of support rollers 16 are rotatably installed in the support frame 15.
[0029] In the embodiment, the size and shape of the opening are matched with the shape of the two-part drill bit 12 in the closed state, which allows the two-part drill bit 12 to smoothly pass through the base 1 into the soil for sampling and facilitates the extraction of the drill bit from the soil and return to above the base 1 after sampling is completed. The slide plate 14 can freely slide on the base 1, the support frame 15 provides a stable mounting platform for the subsequent support rollers 16, and the support rollers 16 can support the two-part drill bit 12 during the transfer of the device to prevent direct contact with the ground due to gravity. The rotating design of the support rollers 16 also facilitates subsequent extraction work.
[0030] In further preferred embodiments of the utility model, the two slide rods 6 are each provided with a scale line, the motor 10 is provided with a battery, and the motor 10 is externally fixed with a waterproof protective shell.
[0031] In the embodiment, the scale line on the slide rod 6 provides intuitive depth indication for the user, and during sampling, the user can accurately control the sampling depth of the drill bit by observing the scale line on the slide rod 6, ensuring that each sampling meets the predetermined requirements. This not only improves the accuracy of sampling, but also facilitates data recording and comparison for the user. The design of the battery enables the sampling device to have independent power supply capability, allowing the user to perform sampling operations without relying on external power sources, greatly improving the portability and flexibility of the sampling device. The endurance of the battery also ensures that the sampling device can work continuously for a long time, meeting the needs of users in different scenarios. The design of the waterproof protective shell effectively protects the motor 10 from external environmental erosion such as water and dust, ensuring the normal operation of the motor 10 during sampling operations in outdoor or humid environments, preventing faults and damage caused by water ingress or short circuits.

The two slide rods 6 are respectively installed in the two clamping barrels 10 through fixed bolts.
[0033] In the embodiment, the design of the limiting frame 9 enhances the connection stability between the slide block 7 and the threaded rod 11, ensuring that the threaded rod 11 can remain stable during rotation and reducing deviation or shaking caused by vibration or external forces. The threaded rod 11 and the limiting frame 9 are rotationally connected, which allows the threaded rod 11 to smoothly rotate under the drive of the motor, thereby driving the drill bit to perform sampling operations. The damping pad can absorb part of the vibration energy, reducing noise and wear, and protecting the drill bit from damage. This improvement improves the stability and durability of the sampling operation.
[0034] Compared with the related art, the device can drive the threaded rod 11 to rotate by setting the motor 10 cooperating with two gear transmissions, drive the two halves of the drill bit 12 to rotate, and make the two halves of the drill bit 12 drill down to the soil sample by cooperating with the gravity of the sliding block 7 and the gear box 8, so that the two halves of the drill bit 12 can be lifted by pulling the sliding block 7, and the sampling purpose is achieved.
