Description

Technical Field

[0001] This utility model relates to the field of soil testing, and in particular to a depth-adjustable structure for soil compaction testing samples. Background Technology

[0002] In the field of soil compaction testing, traditional testing devices often suffer from problems such as insufficient accuracy, cumbersome operation, or limited applicability in depth adjustment. For example, some structures rely on manual adjustment, making it difficult to accurately control the insertion depth and resulting in poor repeatability of test data. Some fixed-depth designs cannot adapt to testing scenarios with different soil layers or different crop planting needs, affecting testing efficiency and data comprehensiveness. In addition, existing adjustment structures often experience jamming or displacement due to high soil resistance, further reducing testing accuracy. Therefore, developing a depth-adjustable and stable testing structure has become a key requirement for improving the accuracy and applicability of soil compaction testing.

[0003] Existing soil compaction testing sample depth-adjustable structures typically have fixed holding handles. The testing head is pressed into the soil by pressing the handles. Since the required soil depth varies, the rod needs to be extended when deeper testing is required. In actual use, the extended rod usually has the handles at the top, but the longer rod makes it difficult for workers to exert force to press the rod into the soil, causing some inconvenience. Therefore, we propose a soil compaction testing sample depth-adjustable structure. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a depth-adjustable structure for soil compaction testing. By setting a movable handrail, the connection state between the handrail and the rod can be adjusted by an adjuster, so that the position of the handrail can be freely adjusted. When using, the handrail can be adjusted to the most suitable position for pressing, which improves the convenience of the device when breaking the soil.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

The movable rod 309 is movably nested inside the movable groove 304. By tightening the threaded rod 306, the threaded rod 306 extends within the movable groove 304, thereby compressing the movable rod 309 and reducing the space between the movable piece 308 and the fixed piece 307, thus fixing the auxiliary rod 205. A movable handle 303 is provided, which can be adjusted to adjust its connection with the rod body via the adjuster 305, allowing the position of the handle 303 to be freely adjusted. During use, the handle 303 can be adjusted to the most suitable position for pressing, improving the convenience of the device when breaking ground.

[0028] Reference Figure 1-3 As shown, the detection mechanism 2 includes a main rod 201. A connector 202 is provided at the upper end of the main rod 201. An interface 203 is provided on the inner side of the upper end of the connector 202. A connecting rod 204 is movably installed on the inner side of the inner end of the main rod 201. A secondary rod 205 is fixedly connected to the lower end of the connecting rod 204. A detection head 206 is movably connected to the lower end of the secondary rod 205. The secondary rod 205 passes through the through hole 302 and is movably connected to it. The connecting rod 204 and the main rod 201 are threadedly connected. By setting the secondary rod 205, the overall length of the rod can be adjusted by increasing or decreasing the number of secondary rods 205, which improves the adaptability of the device during use.

[0029] Reference Figure 1-2 As shown, the display mechanism 1 includes a work box 101. A control button 102 is provided on the lower side of the lower end of the work box 101. A display screen 103 is provided in the middle of the front end of the work box 101. A connecting line 104 is fixedly connected to the upper end of the work box 101. A connector 105 is fixedly connected to the end of the connecting line 104. By setting the display screen 103, the detection data of the device can be displayed in real time, which is convenient for the staff to observe and record the data.

[0030] Reference Figure 2-3 As shown, the connector 105 is movably connected to the inner side of the inner end of the interface 203. By setting the connector 105 to be movably connected to the inner side of the inner end of the interface 203, the device can be easily connected and disconnected, making the device easy to collect and improving the convenience of using the device.

[0031] Specific implementation process: First, connection is established: the connector 105 is movably nested within the interface 203 of the connector 202 at the upper end of the main rod 201, and data transmission between the two is achieved through a wired connection, ensuring that the detection data can be transmitted to the work box 101 for data processing in real time. According to the detection requirements, the overall length is adjusted: the connecting rod 204 inside the main rod 201 is threadedly connected to the main rod 201, and its extension length within the main rod 201 can be adjusted by rotating the connecting rod 204; simultaneously, by increasing or decreasing the number of auxiliary rods 205, the lower ends of the auxiliary rods 205 are fixedly connected to the connecting rod 204, further precisely controlling the initial depth range of the detection head 206, achieving preliminary adjustment of the detection depth. The retainer 301 is fitted onto the auxiliary rod 205 through the through hole 302. If the current depth needs to be fixed, rotating the adjuster 306 drives the threaded rod 305 to extend threadedly within the movable groove 304, compressing the movable rod 305 nested within the movable groove 304. 9. Move the movable piece 308 closer to the fixed piece 307 to reduce the distance between them, thereby clamping the auxiliary rod 205 and fixing the detection depth to prevent deviation. At the same time, adjust the position of the handle 303: change the connection state between the handle 303 and the fixing device 301 through the adjuster 305, adjust the handle 303 to the most comfortable position for the operator and fix it, so as to facilitate subsequent force to break the soil. The operator holds the adjusted handle 303 and presses the device down: with the force fulcrum of the handle 303, the detection head 206 is driven into the soil. After the detection head 206 contacts the soil, it senses its compaction and converts the physical signal into an electrical signal. The signal of the detection head 206 is transmitted to the work box 101 through the auxiliary rod 205, connecting rod 204, main rod 201, connector 202, interface 203 and connecting line 104. After processing, the detection data is displayed in real time on the display screen 103. The operator can operate the device through the control button 102 and directly read and record the data from the display screen 103.
