Description

Technical Field

[0001] This utility model relates to the technical field of soil sampling, specifically a sampling device for detecting soil moisture in agriculture. Background Technology

[0002] In agricultural production, soil moisture is a key factor affecting crop growth, development, and yield. Accurate soil moisture detection is crucial for rational irrigation, improved water resource utilization efficiency, and ensuring healthy crop growth. Currently, existing agricultural soil moisture sampling devices suffer from problems in practical applications, such as inaccurate sampling depth control, potential damage to soil structure during sampling, and low sampling efficiency. These issues make it difficult to meet the demands of modern agriculture for rapid, accurate, and non-destructive soil moisture detection. Therefore, there is an urgent need to develop a more efficient and accurate agricultural soil moisture sampling device.

[0003] Application number CN202222503014.8 discloses a sampling device for agricultural soil moisture detection, including a horizontal plate and a soil sampling cylinder. A moving mechanism is fixedly connected to the top left side of the horizontal plate, and a first vertical plate is fixedly connected to the right side of the horizontal plate. A water pump is fixedly connected to the bottom left side of the first vertical plate, and a water pump and a hydraulic rod are fixedly connected sequentially from top to bottom to the bottom left side of the first vertical plate. This utility model has the advantages of quick and convenient soil discharge and automatic cleaning function, solving the problem that existing soil sampling devices usually cannot discharge soil quickly and conveniently, causing time and effort for operators to take out sample soil, affecting the efficiency of soil sampling work. Moreover, it does not have an automatic cleaning function, and the residual soil in the device during previous soil sampling cannot be completely removed. During repeated soil sampling, cross-contamination of soil may occur, leading to errors in soil moisture detection and reducing the accuracy of soil moisture detection. However, it has shortcomings. After the device is fixed, it cannot be temporarily moved to different positions for adjustment. This limits the use of the device and lacks the flexibility for emergency adjustment.

The limiting slide rail 304 is fixedly mounted on the top of the mounting plate 104. The brake motor 301 of the sampling assembly 3 drives the sampling drill bit 305 to rotate, thereby achieving soil sampling.

[0032] The adjustable moving support assembly 4 includes a translation groove 401 and a fixed support plate 405. The translation groove 401 is formed on both sides of the bottom of the mounting base plate 101, and a translation mounting plate 402 is slidably installed inside the translation groove 401. A rotating locking clamp 403 is fixedly installed at the bottom of the translation mounting plate 402, and a moving wheel 404 is installed inside the rotating locking clamp 403 for limiting. The fixed support plate 405 is fixedly installed on the bottom front side of the mounting base plate 101 and is positioned in the center. The adjustable moving support assembly 4 slides in the translation groove 401 through the translation mounting plate 402, and with the help of the rotating locking clamp 403 and the moving wheel 404, the device can be moved and positioned flexibly. The fixed support plate 405 provides additional stable support during sampling. The device is placed in the sampling area, and the handle 103 is pushed. The translation mounting plate 402 slides in the translation groove 401, and with the help of the moving wheel 404 rotating in the rotating locking clamp 403, the device is moved to the appropriate position.

[0033] This agricultural soil moisture sampling device is mainly supported by a support assembly 1, with the working position of the sampling assembly 3 controlled by a distance adjustment assembly 2, and the device moved and fixed by an adjustable moving support assembly 4. Specifically, the pneumatic pump 201 in the distance adjustment assembly 2 drives the push rod 202 to adjust the position of the fixed frame 203, thereby adjusting the height of the sampling assembly 3; the brake motor 301 of the sampling assembly 3 drives the sampling drill bit 305 to rotate, achieving soil sampling; the adjustable moving support assembly 4 slides within a translation groove 401 via a translation mounting plate 402, cooperating with a rotary locking clamp 403 and moving wheels 404 to achieve flexible movement and positioning of the device; the fixed support plate 405 provides additional stable support during sampling. The device is placed in the sampling area, and the handle 103 is pushed, allowing the translation mounting plate 402 to slide within the translation groove 401, cooperating with the rotation of the moving wheels 404 within the rotary locking clamp 403 to move the device to the appropriate position. Upon reaching the designated position, the moving wheel 404 is locked by rotating the locking clamp 403, while the fixed support plate 405 supports the ground to ensure the stability of the device. The pneumatic pump 201 is started. The pneumatic pump 201 is fixed to the top of the mounting plate 104 by the bracket. The push rod 202 on its inner side pushes the fixed frame 203. According to the actual needs, the height of the sampling component 3 is adjusted along the adjustment groove 1041 in the middle of the mounting plate 104 so that the sampling drill bit 305 is aligned with the soil to be sampled. The brake motor 301 is started. The brake motor 301 is installed on the top of the mounting base 302 and drives the sampling drill bit 305 at the bottom to rotate at high speed. The limiting sliders 303 on both sides of the mounting base 302 slide in the limiting slide rail 304 to ensure the stable operation of the sampling component 3 during the sampling process. The sampling drill bit 305 drills into the soil through the drilling movable frame 1011 in the middle of the front side of the mounting base 101 to complete the soil sampling. After the sampling is completed, the brake motor 301 is turned off to stop the rotation of the sampling drill bit 305. Restart the pneumatic pump 201, which will lift the fixed frame 203 via the push rod 202, removing the sampling component 3 from the soil. Unlock the rotary locking clamp 403 and move the device to the next sampling point or storage location.
