Description

Technical Field

[0001] This utility model relates to the field of geological sampling technology, and in particular to a soil fertilizer nutrient detection and sampling device. Background Technology

[0002] Soil is the foundation of agricultural production, and its nutrient status directly affects crop growth and yield. Accurately understanding the nutrient content in the soil is crucial for scientifically guiding fertilization. Traditional soil nutrient testing typically requires collecting soil samples and sending them to a laboratory for analysis. However, current technologies face several challenges in soil sample collection. For example, manual sampling is not only inefficient but also struggles to ensure consistent sampling depth and verticality, leading to problems such as equipment tilting and wear, resulting in unrepresentative soil samples that affect the accuracy of subsequent nutrient testing results. Especially when large-area, multi-point sampling is required, manual operation is often labor-intensive and difficult to standardize. Furthermore, when sampling at deep depths or in heavy, sticky soils, pulling the sampling equipment out of the soil requires considerable physical strength, and operators are prone to damage during the process, causing equipment knocks or sample breakage, further reducing work efficiency and sample quality. These problems severely restrict the accuracy and efficiency of soil nutrient testing, making it difficult to meet the growing demand for precision fertilization in modern agriculture.

[0003] Therefore, this utility model proposes a soil fertilizer nutrient detection and sampling device to address the shortcomings of existing technologies. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a soil and fertilizer nutrient detection and sampling device, which aims to improve the problems of inaccurate sampling depth, easy tilting of the equipment leading to wear and tear, and laborious and easily damaged equipment and sample damage when recovering from the soil in the existing soil and fertilizer nutrient detection and sampling devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A soil and fertilizer nutrient testing and sampling device, comprising a sampling device, a support component, and a lifting component.

[0011] The U-shaped support is installed at the top of the handle, and the U-shaped support and the second connecting block are connected by two connecting shafts and two support rods on both sides. The U-shaped support, connecting shafts and handle constitute a force-saving lever structure.

[0012] The lifting component is positioned by cooperating with the second support column through the second positioning pin, and is assembled by lifting the second support column upward through a force-saving lever structure.

[0013] Preferably, the first connecting block is inserted into the groove at the top of the second support column, and the threaded holes of the first connecting block and the second support column are aligned vertically.

[0014] Preferably, the hollow drill rod is connected to the motor inside the motor housing via a motor shaft.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0026] Please refer to Figures 1 to 4 This utility model provides a soil fertilizer nutrient detection and sampling device, which aims to solve the problems of inaccurate sampling depth, power consumption and easy damage of equipment, and sample damage in the prior art.

[0027] like Figure 1 and Figure 2As shown, the soil nutrient testing and sampling device mainly includes a support component 5, a sampling device, and a lifting component 6. The support component 5 serves as the basic frame of the entire device, providing vertical guidance and stable support for the sampling device, and providing a mounting base for the lifting component 6. The sampling device is slidably and lockably connected to the support component 5 for drilling soil. The lifting component 6 is slidably and lockably mounted on the support component 5 in a lever-like manner to assist the sampling device in retrieving soil samples.

[0028] Please refer to the following carefully. Figure 1 , Figure 2 and Figure 3 The core structure will be described in detail below: The support assembly 5 includes a base 51, a first support column 52, and a second support column 53. The base 51 is placed stably on the ground at the sampling point, providing overall stability to the device. The first support column 52 is fixed to the base 51, and the second support column 53 is slidably connected to the interior of the first support column 52. Multiple perforations 57 are formed along the length of the second support column 53. These perforations 57 are used to adjust and lock the height of the second support column 53. The operator can pull out the second support column 53 to the target height according to the sampling requirements, and then insert the first positioning pin 56 into the perforation 57 closest to the first support column 52, thereby locking the height of the second support column 53 and the first support column 52, ensuring accurate sampling depth and vertical stability of the sampling process.

[0029] The sampling device includes a motor housing 1, a handle 2, a motor shaft 3, a switch 4, and a hollow drill rod 7. The motor housing 1 contains a motor, which drives the hollow drill rod 7 to rotate at high speed through the motor shaft 3. The handle 2 is for the operator to hold, and the switch 4 controls the start and stop of the motor. The bottom of the motor housing 1 is also provided with a through hole for fixing the hollow drill rod 7 to ensure that the hollow drill rod 7 is stable and reliable during high-speed rotation and drilling into the soil.

[0030] The motor housing 1 is fixed to the top of the second support column 53 by the first connecting block 55. The first connecting block 55 is inserted into the groove 58 on the top of the second support column 53 in a matching shape. The first connecting block 55 and the threaded hole 59 on the top of the second support column 53 are tightened and fixed by screws 54. This connection method makes the sampling device and the support assembly 5 firmly integrated into a whole, ensuring that the sampling device can move smoothly along the vertical trajectory of the second support column 53 during the drilling process, effectively avoiding equipment tilting and uneven wear. At the same time, the threaded hole 59 of the first connecting block 55 and the second support column 53 are aligned vertically, which greatly facilitates the installation and fixing of the screws 54.

[0031] As a preferred embodiment, in order to ensure efficient and stable operation of the drill rod, the hollow drill rod 7 is connected to the motor inside the motor housing 1 via the motor shaft 3. This transmission connection method can be a commonly used method in the prior art, such as gear transmission, belt transmission or coupling transmission. The specific method can be selected according to the motor output torque and drill rod speed requirements to achieve the best drilling performance.

[0032] As another preferred embodiment, in order to ensure the vertical stability of the sampling device, the second support column 53 slides along the inner cavity of the first support column 52 during the sampling process. This sliding fit design ensures that the sampling device always maintains a vertical trajectory when pressed down, effectively preventing the device from tilting when drilling into the soil, thereby ensuring the accuracy of the sampling depth and the quality of sample collection, and reducing the wear and tear between the hollow drill rod 7 and the soil.

[0033] In another preferred embodiment, in order to achieve precise positioning of the lifting component 6, the second positioning pin 66 is inserted into the corresponding hole on the second support column 53 so that the U-shaped support 64 is in close contact with the second positioning pin 66 and achieves positioning and locking. Specifically, when the U-shaped support 64 is adjusted to the groove 58 of the second support column 53 and the first support column 52, the second positioning pin 66 can be inserted into the preset hole of the second support column 53, and the U-shaped support 64 is firmly fixed in the designated position through its contact surface with the U-shaped support 64, providing a stable fulcrum for subsequent labor-saving lifting operations.

[0034] As another preferred embodiment, in order to facilitate the adjustment of different sampling depths, the perforations 57 are evenly arranged along the length of the second support column 53, so that the operator can finely adjust the extension length of the second support column 53, thereby achieving precise control of the sampling depth and improving the adaptability and flexibility of the device.

[0035] As another preferred embodiment, in order to enable the lifting component 6 to move flexibly and achieve a lever effect, the support rod 62 is connected to the connecting shaft 63 in a pivotal manner. This pivotal connection is usually achieved through a pin or a shaft, allowing the support rod 62 to rotate relative to the connecting shaft 63. This allows the U-shaped support 64 to swing smoothly up or down when the operator presses the grip rod 65 to complete the lifting or lowering operation.

[0036] As another preferred embodiment, the bottom of the motor housing 1 is also provided with a through hole for fixing the hollow drill rod 7. The through hole can firmly connect the hollow drill rod 7 to the motor shaft 3, preventing it from shaking during high-speed rotation and drilling, and ensuring operational safety and efficiency.

[0037] Working principle: Before soil sampling, the staff first places the base 51 of the support component 5 stably on the ground at the sampling point, ensuring that the base 51 is in contact with the ground to provide stable support. Then, according to the sampling requirements, the second support column 53 is slid out from the inside of the first support column 52 and adjusted to the target height. Using the multiple holes 57 on the second support column 53, the first positioning pin 56 is inserted into the hole 57 closest to the first support column 52 to lock the height of the second support column 53 and the first support column 52. Next, the first connecting block 55 is installed on the motor housing 1. The first connecting block 55 is aligned with the groove 58 on the top of the second support column 53 and inserted. Then, the screw 54 is aligned with the threaded hole 59 on the top of the second support column 53 and the first connecting block 55. The screw 54 is rotated until it is tightened, and the first connecting block 55 is firmly fixed in the groove 58. At this point, the installation and height locking of the sampling device and the support component 5 are completed, providing a stable and adjustable vertical guide for subsequent sampling operations. After the device is fixed, the operator pulls out the first positioning pin 56, holds the device handle 2 with both hands and presses the switch 4. The motor inside the motor box 1 starts immediately, driving the hollow drill rod 7 to rotate at high speed through the motor shaft 3. The operator presses down on the handle 2 to make the sampling device gradually drill into the soil along the vertical trajectory of the support component 5 until the hollow drill rod 7 reaches the preset sampling depth. During this period, the sampling device moves vertically along the sliding trajectory of the second support column 53 in the first support column 52. Since the second support column 53 provides precise vertical guidance in the first support column 52, it effectively avoids the tilting of the device during the sampling process, reduces the wear and tear between the hollow drill rod 7 and the soil, and ensures accurate sampling depth, greatly improving the sample collection quality. When sampling is complete and the equipment needs to be retrieved from the soil, the lifting assembly 6, which is part of the support assembly 5, enables labor-saving operation. The operator first lifts the handle 65 of the lifting assembly 6. Two U-shaped supports 64 are symmetrically installed on the top of the handle 65. Since the U-shaped supports 64 are fixed to the second connecting block 61 of the first support column 52, a sliding connection is formed between the two support rods 62 and the two connecting shafts 63 installed on both sides of the U-shaped supports 64 and the second connecting block 61. The operator can push the handle 65 to move the U-shaped supports 64, precisely adjusting them to the groove 58 near the position of the second support column 53 and the first support column 52. Then, the second positioning pin 66 is inserted, ensuring tight contact between the U-shaped supports 64 and the second positioning pin 66, thus locking the lifting assembly 6. At this point, the U-shaped supports 64, the connecting shafts 63, and the handle 65 constitute a simple, labor-saving lever structure, with the connecting shaft 63 serving as the lever fulcrum. 5 is the power end, and the contact point between the U-shaped support 64 and the second positioning pin 66 is the resistance end. When the operator presses down on the grip 65, the power arm is longer than the resistance arm due to the sliding support of the second connecting block 61 and the support rod 62 through the connecting shaft 63. Through the effort-saving lever effect, the U-shaped support 64 can easily lift the second support column 53 inserted into the second positioning pin 66 upward. During the rise of the second support column 53, the first connecting block 55, which is fixed at its top by the screw 54, simultaneously lifts the sampling device, allowing the hollow drill rod 7 to be smoothly removed from the soil. When the equipment is raised to the required height, the first positioning pin 56 is inserted into the hole 57 closest to the first support column 52 to lock the height of the second support column 53 and the first support column 52, preventing the equipment from falling back. This greatly reduces the physical exertion of the operator and avoids equipment collisions or sample damage caused by manual lifting, thereby improving work efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
