Description

Technical Field

[0001] This utility model relates to the field of geological exploration equipment technology, specifically a combined whole-section soil sample box. Background Technology

[0002] With the deepening and widespread application of geological exploration, soil sample collection and preservation have become crucial tasks in geological exploration. Especially in fields such as environmental investigation, soil pollution assessment, and resource exploration, the integrity and accuracy of soil samples directly affect the reliability of analytical results. However, many existing soil sampling devices and methods still suffer from problems such as complex sampling procedures, long cycles, and the ease with which samples can break during sampling, affecting the efficiency of exploration work and sample quality.

[0003] Existing soil sampling devices mostly employ traditional manual sampling methods, requiring sampling personnel to complete a series of cumbersome procedures to collect samples. These procedures include using different types of sampling tools, digging soil layers, stratified sampling, and preliminary sample processing. While these methods can obtain soil samples of a certain quality, the cumbersome operation and high technical requirements of the personnel often lead to low sampling efficiency, and may even result in the loss or breakage of some samples, affecting subsequent analysis and evaluation.

[0004] Furthermore, a common problem with existing sampling devices is insufficient protection of samples during the sampling process. Soil samples, especially in areas with loose soil or high water content, are easily broken, lost, or contaminated due to external forces or the weight of the sample itself. In particular, the design of the sampling chamber fails to effectively prevent sample movement or damage during sampling, leading to changes in soil structure and composition, which in turn affects the accuracy of analytical results.

[0005] To address the shortcomings of existing technologies, this utility model provides a combined whole-section soil sample box, including a sample preservation box and a soil breaking module. The soil breaking module includes a base plate and a cutter. The base plate has an opening in the middle that is the same shape as the inner wall of the sample preservation box. The edge of the opening of the base plate is surrounded by a cutter for cutting the soil. The cutter includes a longitudinal cutter and a transverse cutter. The longitudinal cutter and the transverse cutter are connected end to end in sequence and are perpendicular to the base plate.

[0006] Preferably, an oblique cutter is provided between the connection point of each of the longitudinal cutter, the transverse cutter and the connection point of the base plate, the oblique cutter being used to strengthen the connection between the longitudinal cutter and the transverse cutter.

[0007] Preferably, the inner surface of each of the longitudinal and transverse cutters is provided with a triangular stabilizing plate to increase connection strength and improve torsional resistance.

[0008] Preferably, the base plate is provided with a plurality of ventilation holes evenly distributed to prevent the soil from adhering and forming negative pressure.

[0009] Preferably, the base plate is provided with a depth detection module for detecting the cutting depth.

[0010] Preferably, the depth detection module includes a cylindrical shell, a mandrel, a push plate, a spring, and a retaining ring.

[0018] Example

[0019] The following is combined with Figures 1 to 2 This application introduces a combined whole-section soil sample box, including a sample storage box 100 and a soil breaking module. The soil breaking module includes a base plate 1 and a cutter. The base plate 1 has an opening in the middle that is the same shape as the inner wall of the sample storage box 100. The edge of the opening of the base plate 1 is surrounded by a cutter for cutting the soil. The cutter includes a longitudinal cutter 2 and a transverse cutter 3. The longitudinal cutter 2 and the transverse cutter 3 are connected end to end in sequence and are perpendicular to the base plate 1.

[0020] An oblique cutter 4 is provided between the connection point of each of the longitudinal cutter 2 and the transverse cutter 3 and the connection point of the base plate 1. The oblique cutter 4 is used to strengthen the connection strength between the longitudinal cutter 2 and the transverse cutter 3.

[0021] Each of the longitudinal cutters 2 and transverse cutters 3 has a triangular stabilizing plate 5 on its inner side to increase connection strength and improve torsional resistance.

[0022] The base plate 1 is evenly provided with multiple ventilation holes 6 to prevent the soil from sticking together and forming negative pressure.

[0023] The base plate 1 is equipped with a depth detection module for detecting the depth of the cutter. The depth detection module includes a cylindrical shell 7, a spindle 8, a push plate 9, a spring 10, and a retaining ring 11. The cylindrical shell 7 is located on the side of the base plate 1 where the cutter is not installed. A spindle 8 with both ends penetrating the cylindrical shell 7 and the base plate 1 is installed in the cylindrical shell 7. The portion of the spindle 8 inside the cylindrical shell 7 is equipped with a retaining ring 11. A spring 10 with an elastic force that pushes the spindle 8 toward the cutter is installed between the retaining ring 11 and the cylindrical shell 7. A push plate 9 is provided on the end of the spindle 8 that protrudes from the base plate 1 to increase the contact area with the soil. A scale is provided on the end of the spindle 8 that protrudes from the cylindrical shell 7. The scale is used to visually view the depth of the cutter and facilitate the acquisition of standard soil samples.

[0024] The bottom plate 1 is provided with a relief concave ring 12 on the side facing the push plate 9, which is adapted to the shape of the push plate 9, thereby increasing the maximum depth of soil sample acquisition.

[0025] One method of use: Align the cutting edges of the longitudinal cutter 2 and the transverse cutter 3 with the soil sample to be obtained, press them into the soil, and check the depth through the scale at one end of the mandrel 8 that protrudes from the cylindrical outer shell 7. Use a scraper or other tools to remove excess soil along the outer walls of the longitudinal cutter 2 and the transverse cutter 3. The oblique cutter 4 acts as a punch in the forging process, maintaining the strength of the soil and preventing it from collapsing and breaking, thus ensuring the integrity of the soil sample. Then pull out the bottom plate 1 until the longitudinal cutter 2 and the transverse cutter 3 are completely detached from the soil. At this point, press the sample storage box 100 into the soil sample, and use a shovel or wire saw to cut the soil along the sample storage box 100 to obtain a complete soil sample.
