Description

Technical Field

[0001] This utility model relates to the field of soil sampling, and in particular to a sensor-enabled electric columnar soil sampler. Background Technology

[0002] Soil samplers are instruments designed to meet the requirements of sampling the surface and inner layers of soil, as well as quantity and convenience. They solve the problem of accurately collecting soil samples, which is difficult to achieve in soil testing and fertilizer application, and soil monitoring and fertility work. Soil samplers usually have the characteristics of being able to sample different soil textures and being small in size and easy to carry outdoors.

[0003] For example, the announcement CN102692335A, titled "A Portable Columnar Soil Sampler," includes a handle, a sleeve, a support rod, a connector, a sampler, and a shrink tube. The handle is a round tube; the sleeve is a round tube, with the center of the handle's round tube vertically welded to the upper end of the sleeve; the support rod is a round tube, with its upper end inserted into the sleeve from the lower end. Furthermore, the outer wall of the upper end of the support rod has a rectangular convex key, and the inner wall of the sleeve also has a rectangular concave keyway. The rectangular key is placed within the rectangular concave keyway. This ensures that the soil sample will not slip, allowing sampling in loose soil where the sample is difficult to shape.

[0004] The existing technical solutions mentioned above have the following drawbacks: during the soil sampling process, since the underground soil is not visible, the user cannot accurately determine whether the required soil depth has been reached or exceeded, and the accuracy of the sampling depth is insufficient; in addition, since the sampler requires manual sampling throughout the sampling process, it is very time-consuming and labor-intensive.

[0059] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0060] Please see Figures 1 to 5 This embodiment provides a sensorable, electrically driven columnar soil sampler, including an outer cylinder 1, a control component 2, a telescopic component 3, a connecting plate 4, an inner cylinder 5, a handle 6, and an anchoring cone 7. The outer cylinder 1 includes a first upper part 11 and a first lower part 12. The first upper part 11 has a first chamber 111, a first upper end 114, and a first lower end 113. The first upper end 114 and the first lower end 113 are located at both ends of the first chamber 111. The first lower end 113 has a first opening that communicates with the first chamber 111. The first lower part 12 has a second chamber 121, a second upper part 123 and a second lower part. The second upper part 123 and the second lower part are located at both ends of the second chamber 121. The second upper part 123 has a second opening and the second lower part has a third opening 122. Both the second opening and the third opening 122 are connected to the second chamber 121. The first lower part 113 and the second upper part 123 are detachably connected. The second opening is adapted to the first opening. The first chamber 111 and the second chamber 121 can be connected to form a whole.

[0061] Control component 2 includes a display screen 21, a sensor, a control unit 22, and a first drive unit 23. Control component 2 is disposed within the first chamber 111. The display screen 21 is disposed on the upper part 11, facing away from the first opening. The sensor, control unit 22, and first drive unit 23 are disposed within the first chamber 111. The control unit 22 is electrically connected to the first drive unit 23, the sensor, and the display screen 21, respectively. Telescopic component 3 includes a first telescopic rod 31, which is drively connected to the first drive unit 23. A connecting plate 4 is provided. At the movable end of the first telescopic rod 31, the connecting plate 4 is coaxially arranged with the outer cylinder 1; the inner cylinder 5 is coaxially arranged with the connecting plate 4, and the inner cylinder 5 is placed in the second chamber 121. The inner cylinder 5 has a third chamber 52, a third upper end and a third lower end. The third upper end is detachably connected to the connecting plate 4, and the third lower end is provided with a fourth opening 51, which communicates with the third chamber 52. The third lower end has an inclined structure; the handle 6 is hinged to the outer cylinder 1, and the handle 6 can rotate relative to the outer cylinder 1; the anchoring cone 7 is arranged in the circumferential direction of the second lower end.

[0062] In this embodiment, the outer cylinder 1 and the inner cylinder 5 can be made of the same material, such as hollow steel pipe, alloy pipe, etc. The outer cylinder 1 and the inner cylinder 5 are distinguished by their positional relationship, wherein the inner cylinder 5 is placed inside the outer cylinder 1 and the inner cylinder 5 is coaxially arranged with the outer cylinder 1. During the sampling process, the outer cylinder 1 remains relatively fixed with respect to the soil, and the inner cylinder 5 can extend downward into the soil to sample the soil.

[0063] Specifically, the outer cylinder 1 is divided into a first upper part 11 and a first lower part 12, which are detachably connected. The first upper part 11 is mainly used to install the control component 2, and the first lower part 12 is mainly used to accommodate the inner cylinder 5. The detachable connection between the first upper part 11 and the first lower part 12 facilitates the collection of soil after soil sampling. Furthermore, the first upper part 11 includes a first chamber 111, a first upper end 114, and a first lower end 113. The first upper end 114 can be a closed structure or a hollow structure to facilitate the installation of the display screen 21 described later. The first upper end 114 and the first lower end 113 are defined by their vertical positional relationship when the soil sampler is used correctly. Similarly, the second upper end 123, the second lower end, the third upper end, and the third lower end described later can all be understood in the same way. The first upper end 114 and the first lower end 113 are the two ends of the first upper part 11. A first chamber 111 is provided in the first upper part 11. The first chamber 111 is used to accommodate the control component 2. A first opening is provided on the first lower end 113. The first opening communicates with the first chamber 111, which facilitates the assembly of the control component 2.

[0064] The first lower part 12 includes a second chamber 121, a second upper end 123, and a second lower end. The second upper end 123 and the second lower end are the two ends of the first lower part 12. A second opening is provided on the second upper end 123, which communicates with the second chamber 121. The inner cylinder 5 is placed inside the second chamber 121, and the second upper end 123 is detachably connected to the first lower end 113. When the first upper part 111 is connected to the first lower part 12, the first chamber 111 and the second chamber 121 communicate to form a complete cavity. The first opening and the second opening coincide. A third opening 122 is provided at the second lower end, allowing the inner cylinder 5 to extend out from the first lower part 12 for soil sampling.

[0065] The control component 2 includes a display screen 21, sensors, a control unit 22, and a first drive unit 23. The display screen 21 can be mounted on the upper part 114 for easy user access. The display screen 21 can show the current working status of the soil sampler, such as specific sampling status information, sampling depth information, and whether any abnormalities have been encountered during sampling. The sensor is a depth sensor, specifically an ultrasonic sensor, photoelectric sensor, pressure sensor, or distance sensor, etc. The sensor is electrically connected to the control unit 22. The control unit 22 can receive the depth information collected by the sensor in real time and display it on the display screen 21. The control unit 22 can be an MCU chip. The first drive unit 23 can be a servo motor. The first drive unit 23 can provide driving force to the telescopic component 3 to realize the automatic downward movement of the inner cylinder 5, eliminating the need for manual rotation of the inner cylinder 5 for downward soil sampling.

[0066] In some embodiments, the sampler further includes a sensing ring disposed at the third lower end, the sensing ring being configured to be recognizable by a sensor.

[0067] The material of the sensing ring can be selected based on the working principle of the sensor. For example, when the sensor is an ultrasonic sensor, it is preferable to choose a material that strongly reflects ultrasonic waves; similarly, when the sensor is a photoelectric sensor, it is preferable to choose a material that strongly reflects light signals, and so on. With the sensing ring located at the lower third end, during the descent of the inner cylinder 5, the control unit 22 can control the sensor to emit a detection signal at a fixed frequency and receive the corresponding reflected signal. Then, it identifies the reflected signal of the sensing ring from multiple reflected signals, performs corresponding logical calculations, and calculates the current distance between the sensing ring and the sensor, thereby detecting the insertion depth of the inner cylinder 5. By setting up the sensing ring, the influence of the soil internal environment on the sensor's detection accuracy can be effectively reduced, thus improving the accuracy of the depth information acquisition of the inner cylinder 5.

[0068] Please see Figure 3In some embodiments, the first lower end portion 113 and the second upper end portion 123 are threadedly connected; and / or, the third upper end portion and the connecting disk 4 are magnetically connected. The threaded connection ensures a stable connection between the first upper part 11 and the first lower part 12, while the magnetic connection between the third upper end portion and the connecting disk 4 facilitates the user's disassembly and assembly of the inner cylinder 5 after sampling, thereby improving sampling efficiency.

[0069] Furthermore, the telescopic assembly 3 includes a first telescopic rod 31, which is connected to the output end of the first drive unit 23. The first drive unit 23 can drive the first telescopic rod 31 to extend downward or retract upward. During soil sampling, the first drive unit 23, under the control of the control unit 22, drives the first telescopic rod 31 and the inner cylinder 5 to extend downward. After reaching the specified soil depth, the first telescopic rod 31 is driven upward to retract the inner cylinder 5 into the second chamber 121, thereby completing one soil sampling.

[0070] Specifically, the output end of the first telescopic rod 31 is equipped with a connecting plate 4, and an inner cylinder 5 is mounted on the connecting plate 4. The inner cylinder 5 is detachably connected to the connecting plate 4, which facilitates the removal of the sampled soil. For ease of description, the structure of the inner cylinder 5 is divided into a third chamber 52, a third upper end, a third lower end, and a fourth opening 51. The fourth opening 51 is located at the third lower end, and the third chamber 52 communicates with the fourth opening 51. Thus, the third chamber 52 can be used to accommodate soil entering through the fourth opening 51 during the descent of the inner cylinder 5. The third upper end is detachably connected to the connecting plate 4. Optionally, the third lower end has a sloped structure, as shown in the figure below. Figure 2 As shown, the inclined structure at the lower end of the third part makes the lower end of the inner cylinder 5 form a structure similar to the tip of a straw, which can better cut into the soil and facilitate soil sampling.

[0071] In this embodiment, a handle 6 is provided on the outer cylinder 1. The handle 6 can be formed by bending steel wire or by binding with rope. In some embodiments, the handle 6 is a leather handle. The handle 6 facilitates the user's convenient handling, moving, and placement of the sampler when sampling at multiple points, thereby improving sampling efficiency.

[0072] In this embodiment, a plurality of anchoring cones 7 are provided at the second lower end. The number of anchoring cones 7 is preferably four, which are equidistantly distributed in the circumferential direction of the second lower end. The anchoring cones 7 can fix the outer cylinder 1 relative to the soil, which facilitates unidirectional soil sampling by the inner cylinder 5 and improves sampling efficiency.

[0073] In some embodiments, the display screen 21 is a touch display screen 21, on which the user can input the soil depth information to be sampled, so that the control unit 22 can perform corresponding command control on the first drive unit 23.

[0074] Please seeFigure 3 In some embodiments, the control component 2 further includes a button 25, which is disposed on the first upper end 114, adjacent to the display screen 21, and electrically connected to the control unit 22. The number of buttons 25 can be multiple, and the mode and model of the buttons 25 can be set according to actual needs. The button 25 facilitates the user to input and modify soil depth information, so that the control unit 22 can perform corresponding command control on the first drive unit 23.

[0075] Please see Figure 3 In some embodiments, the control component 2 further includes an alarm 26, which is disposed in the first chamber 111 and electrically connected to the control unit 22. The alarm 26 may be an audible and visual alarm, a buzzer, a vibrator, etc. The alarm 26 can promptly notify the user when the soil sampler malfunctions, thereby improving sampling efficiency and avoiding repeated sampling or unnecessary waiting in abnormal areas.

[0076] Accordingly, this embodiment also provides specific steps for using the soil sampler:

[0077] Step 1: First, use the handle 6 to carry the sampler to the sampling point, and then use the anchoring cone 7 to fix the sampler on the ground;

[0078] Step 2: Start the sampler control unit 22 via the display screen 21, adjust the desired soil sampling depth on the display screen 21 and start sampling.

[0079] Step 3: Control unit 22 controls first drive unit 23 to drive first telescopic rod 31 to descend, thereby driving connecting plate 4 to descend. During the descent, connecting plate 4 pushes inner cylinder 5 to descend. At the same time as the descent, sensor determines whether the set sampling depth has been reached by sensing the change in pressure on first telescopic rod 31.

[0080] Step 4: If the inner cylinder 5 encounters a stone or other foreign object during its descent, preventing it from continuing to descend and causing sampling to stop, the pressure on the first telescopic rod 31 will increase dramatically. The sensor will then send an alarm signal to the display screen 21 and terminate sampling. The user can pick up the sampler and change the sampling point to resample. If the inner cylinder 5 reaches the set sampling depth, the sensor will send a signal to the first drive unit 23, which will drive the first telescopic rod 31 and the connecting plate 4 to rise, thereby raising the inner cylinder 5. At this point, the sampler can be opened and the soil sample taken out through the detachable connection between the first upper part 11 and the first lower part 12, and then the sampler can be restored.

[0081] This embodiment uses sensors, a display screen 21, and a control unit 22 to precisely adjust and sense the sampling depth. When encountering foreign objects such as stones during sampling, it automatically stops sampling to prevent damage to the sampler. The detachable connection between the first upper part 11 and the first lower part 12, and the detachable connection between the connecting plate 4 and the inner cylinder 5, allows for easier replacement of damaged components when one component malfunctions, eliminating the need to replace the entire sampler and saving costs. It also facilitates soil collection after sampling. The handle 6 allows for easier movement of the sampler when sampling points are close together. The anchoring cone 7, inserted into the soil, provides better fixation of the sampler.

[0082] Please see Figure 4 In some embodiments, the control component 2 further includes a second drive unit 24, which is electrically connected to the control unit 22 and is disposed on the connecting plate 4; the telescopic component 3 further includes a second telescopic rod 32, which is disposed on the connecting plate 4 and is placed in the third chamber 52, and is connected to the output end of the second drive unit 24; the sampler further includes a push plate 8, which is disposed at the output end of the second telescopic rod 32 and is movable relative to the inner cylinder 5 in the third chamber 52.

[0083] In this embodiment, the second drive unit 24 can be a servo motor, the second telescopic rod 32 is connected to the second drive unit 24, and the end of the second telescopic rod 32 is provided with a push plate 8, which is placed in the third chamber 52. After the inner cylinder 5 is sampled, the second drive unit 24 can be controlled to drive the second telescopic rod 32, so that the push plate 8 can push out the sampled soil in the inner cylinder 5 completely, thereby saving the disassembly and assembly process of the inner cylinder 5 and making the whole soil sampler easier to use.

[0084] It should be noted that the soil samples generally have stratified sampling requirements. In this embodiment, a cylindrical glass cup with a diameter similar to that of the outer cylinder 1 can be selected first, and then the fourth opening 51 can be aligned with the top of the cylindrical glass cup. After that, the display screen 21 or button 25 can be pressed to control the push plate 8 to gradually push the soil sample into the cylindrical glass cup, so as to achieve complete soil sample collection.

[0085] For further details, please refer to Figure 4In some embodiments, the control component 2 further includes a connecting harness 28 and a spring 27. The connecting harness 28 is used to connect the second drive unit 24 and the control unit 22. The spring 27 is disposed in the first chamber 111, and its end is connected to the connecting harness 28. The spring 27 is used to wind up the connecting harness 28. The connecting harness 28 is the cable required to connect the control unit 22 and the second drive unit 24. In this embodiment, the position of the spring 27 can be referenced. Figure 4 As shown, when the first telescopic rod 31 extends downward, the second drive unit 24 moves downward, the spring 27 is stretched, and the connecting harness 28 moves downward. When the first telescopic rod 31 retracts upward, the second drive unit 24 moves upward, and the connecting harness 28 is wound up and stored under the elastic potential energy of the spring 27. The entire device standardizes the storage operation of the connecting harness 28.

[0086] Please see Figure 5 In some embodiments, the handle 6 is hinged to the first upper part 11 at a first hinge point and a second hinge point, with the first hinge point and the second hinge point being opposite each other. The first upper part 11 also has a first storage groove 112, which is U-shaped. One end of the first storage groove 112 has a first hinge point, and the other end of the first storage groove 112 has a second hinge point. The handle 6 can be placed inside the first storage groove 112. Through the hinged connection, the handle 6 can rotate and adjust on the first upper part 11, thereby adapting to different usage scenarios and needs and improving the flexibility of the overall structure. Placing the handle 6 inside the U-shaped first storage groove 112 allows for convenient storage and retrieval of the handle 6. When not in use, the entire structure can be stored and carried more compactly, improving portability and storage efficiency. This avoids interference with the overall structure or space occupation when not in use. It also makes the overall appearance simpler and more aesthetically pleasing, avoiding the problem of the handle 6 being exposed and affecting the aesthetics.

[0087] The sampler in the above technical solution, through the setting of sensors, display screen 21, and control unit 22, can accurately adjust and sense the sampling depth, and automatically stop sampling when encountering foreign objects such as stones during the sampling process to prevent damage to the sampler. The sampler in the above technical solution, through the setting of control component 2 and telescopic component 3, enables the sampler to automatically complete the entire sampling process, saving time and manpower spent on soil sampling. The sampler in the above technical solution, through the detachable connection between the first upper part 11 and the first lower part 12, and the detachable connection between the connecting plate 4 and the inner cylinder 5, allows for easier removal and replacement of a damaged structure when it becomes inoperable, eliminating the need to replace the entire sampler, thus saving costs and facilitating soil collection after sampling. The sampler in the above technical solution, through the connection of handle 6, allows for easier movement of the sampler when the distance between sampling points is short. The sampler in the above technical solution, through the setting of anchor cone 7, inserts the anchor cone 7 into the soil, which better secures the sampler.

[0088] The above description is only a part of the embodiments of this utility model, and does not limit the scope of protection of this utility model. Any equivalent device or equivalent process transformation made based on the content of this utility model specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this utility model.
