Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction equipment technology, specifically to a soil sampling device for water conservancy engineering construction. Background Technology

[0002] During the construction of water conservancy projects, the quality and characteristics of the soil are crucial to the stability and safety of the project, and soil samples need to be taken and tested using a sampler.

[0003] For example, an existing Chinese authorized patent (publication number: CN211904686U) discloses a high-efficiency soil sampling device, including a base, a support, a conveying mechanism, and a collection mechanism. The collection mechanism includes a first motor, a driving gear, a driven gear, a threaded tube, a cylinder, a piston, and a cutter head. The support includes a support rod, a limiting rod, and a top plate. The conveying mechanism includes a second motor, a drive wheel, and a driven wheel. This high-efficiency soil sampling device is ingeniously designed. The motor drives the gear to rotate, and the gear drives the threaded tube to rotate, thereby allowing the threaded tube to drill into the soil for sampling. The cylinder pushes out the soil from the threaded tube, saving manpower and sampling time. The conveying mechanism moves the storage box to sample soil at different depths separately, improving sampling efficiency. This high-efficiency soil sampling device is also equipped with casters, making the device more flexible and convenient to move.

[0004] The high-efficiency soil sampling device designed above, compared with known technologies, has a sampling tube that lacks a disassembly structure, making internal cleaning inconvenient. Residual soil accumulates on the fixed tube wall. According to monitoring data from the Ministry of Water Resources, the cross-contamination rate reaches 17% after three consecutive samplings.

[0005] In view of this, a soil sampling device for water conservancy engineering construction is provided to overcome the above-mentioned defects. Utility Model Content

[0030] In this embodiment, the operator first holds the holding plate 1, with the sampling tube 6 at the bottom in contact with the ground. The motor 2 is started by an external latch, and the motor 2 rotates the brake shaft 3 and the sampling tube 6 at the bottom. The sampling tube 6 at the bottom drills into the ground to take a sample. After taking the sample, the components in the connecting mechanism 7 are released from the latch. Next, the components in the positioning mechanism 10 are adjusted, and the components in the positioning mechanism 10 are released from the latch, so that the cover plate 8 is disengaged from the sampling tube 6. Then, the ejection mechanism 11 is started by an external switch, and the ejection mechanism 11 ejects the sample from the sampling tube 6. Example

[0031] The fixing mechanism 5 includes a fixing member 12, a fixing hole 13 and a fixing bolt 14. The fixing member 12 is symmetrically arranged at the connection between the bushing 4 and the sampling tube 6. The fixing member 12, the bushing 4 and the sampling tube 6 are symmetrically provided with fixing holes 13 on one side. The fixing bolt 14 is threadedly connected to the fixing hole 13.

[0032] The connecting mechanism 7 includes a connecting block 15 and a connecting port 16. The connecting block 15 is symmetrically arranged on both sides of the cover plate 8, and the connecting port 16 is symmetrically excavated on both sides of the front surface of the sampling tube 6. The dimensions of the inner walls of the connecting block 15 and the connecting port 16 are matched.

[0033] The positioning mechanism 10 includes a return spring 17, a moving rod 18, a positioning rod 19, and a positioning port 20. The return spring 17 is symmetrically arranged at the bottom of the inner cavity of the opening 9. The moving rod 18 is provided at the top of the return spring 17, and the positioning rod 19 is provided at the bottom of the moving rod 18.

[0036] In summary, with the help of the above-mentioned technical solution of this utility model, when using this device, the operator first holds the holding plate 1, and the sampling tube 6 at the bottom contacts the ground. The motor 2 is started by the external locking mechanism. The motor 2 drives the brake shaft 3 and the sampling tube 6 at the bottom to rotate. The sampling tube 6 at the bottom drills into the ground to take a sample. After taking the sample, the moving rod 18 is pulled. The moving rod 18 transmits the pulling force to the return spring 17, causing the return spring 17 to deform and adjust the moving rod 18 with the components on it. The positioning rod 19 connected to the bottom fixing rod of the moving rod 18 is driven to release the engagement with the inner wall of the positioning port 20. Then, the connecting block 15 is driven by the cover plate 8 to release the engagement with the inner wall of the connecting port 16, so that the cover plate 8 is disengaged from the sampling tube 6. Finally, the electro-hydraulic push rod 22 is started by the external switch. The electro-hydraulic push rod 22 moves with the ejector plate 23, and the ejector plate 23 ejects the sample in the sampling tube 6.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
