Description

Technical Field

[0001] This utility model relates to the field of soil testing and sampling technology, and in particular to a sampling device for soil testing before earthwork excavation. Background Technology

[0002] In earthwork excavation projects, soil testing is an important part of ensuring construction safety, quality and environmental protection. Soil sampling is generally required to accurately assess the physical and chemical properties of underground soil.

[0003] Soil sampling technology mainly relies on hollow cylinder samplers. The sampler inserts a hollow cylinder into the soil, uses its sharp edges to cut the soil, and preserves a certain volume of soil sample in its cavity. After sampling, the sampler is pulled out of the soil, and then the soil in the cavity is pushed out in one piece by mechanical or manual means for further analysis.

[0004] After soil sampling is completed, workers typically use a pusher or other tools to squeeze the soil column out of the cavity. If there are loose layers or fragile structures inside the soil column, these loose layers can easily disintegrate when subjected to external pressure, causing the soil column to lose its original integrity. This results in the soil samples, which were originally clearly layered, becoming mixed together, making subsequent stratification analysis extremely difficult. Soil at different depths may have different compositions, moisture content, and densities, and these differences are important bases for soil quality testing. If soil samples are mixed, it is difficult to accurately distinguish the characteristics of each soil layer, thus affecting the decision-making of the entire earthwork excavation project. Utility Model Content

[0005] In view of this, the present invention provides a sampling device for soil quality testing before earthwork excavation, which can overcome the shortcomings of soil at different depths having different compositions, moisture and density, and these differences are important basis for soil quality testing. If the soil samples are mixed, it is difficult to accurately distinguish the characteristics of each soil layer.

[0006] The technical solution is as follows: A sampling device for soil quality testing before earthwork excavation includes an installation plate, a handle, a support plate, a motor, an installation block, a fixed arc plate, a rotating arc plate, and a connecting block. The top of the installation plate is connected to a handle, and the bottom of the installation plate is connected to a support plate and a motor. The output shaft of the motor is rotatably connected to the bottom of the support plate. The installation block is connected to the output shaft of the motor. The bottom of the installation block is connected to a fixed arc plate, and the bottom of the installation block is hinged to a rotating arc plate. The rotating arc plate and the fixed arc plate are in contact to form a complete sampling tube. Connecting blocks are connected to both the installation block and the rotating arc plate. The connecting blocks on the installation block and the connecting blocks on the rotating arc plate are connected by bolts.

[0007] Optionally, it also includes arc-shaped cutting blocks, with arc-shaped cutting blocks connected to the bottom of both the fixed arc-shaped plate and the bottom of the rotating arc-shaped plate. The two arc-shaped cutting blocks contact each other to form a complete ring-shaped cutting blade.

[0008] Optionally, it also includes a guide block, with a guide groove on the rotating arc plate and a guide block connected to the fixed arc plate, the guide block being located in the guide groove.

[0009] Optionally, it also includes a magnetic block, with a magnetic block connected in the guide groove for attracting the guide block.

[0010] Optionally, it also includes a rubber block, which is connected to the rotating arc plate and contacts the fixed arc plate.

[0011] Optionally, the fixed curved plate has scale lines on both the left and right sides.

[0012] The beneficial effects are as follows: This utility model can drive the fixed arc plate and the rotating arc plate to rotate through the output shaft of the motor, so that the fixed arc plate and the rotating arc plate can be drilled into the soil. The soil will enter the fixed arc plate and the rotating arc plate to take samples. After the sampling is completed, the rotating arc plate is rotated upward to separate the rotating arc plate and the fixed arc plate. The soil is completely retained in the fixed arc plate, so as to accurately distinguish the soil layers and conduct detection and analysis on soil at different depths. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0021] Reference Figure 1 and Figure 2 A sampling device for soil quality testing before excavation includes a mounting plate 1, handles 2, a support plate 3, a motor 4, a mounting block 5, a fixed arc plate 6, a rotating arc plate 7, and connecting blocks 8. Five handles 2 are evenly spaced at the top of the mounting plate 1. The support plate 3 is bolted to the bottom of the mounting plate 1. The motor 4 is bolted to the bottom of the mounting plate 1, and its output shaft is rotatably connected to the bottom of the support plate 3. The mounting block 5 is connected to the output shaft of the motor 4. The fixed arc plate 6 is connected to the rear bottom of the mounting block 5. The fixed arc plate 6 has graduation lines on both its left and right sides. The rotating arc plate 7 is hinged to the front bottom of the mounting block 5. The rear side of the rotating arc plate 7 contacts the front side of the fixed arc plate 6, forming a complete sampling tube. Connecting blocks 8 are connected to the left and right sides of the mounting block 5 and the upper left and right sides of the rotating arc plate 7. The connecting blocks 8 on the mounting block 5 and the rotating arc plate 7 are bolted together.

[0022] Reference Figure 1 It also includes an arc-shaped cutting block 9. The bottom of the fixed arc plate 6 and the bottom of the rotating arc plate 7 are both connected to the arc-shaped cutting block 9. The two arc-shaped cutting blocks 9 are in contact with each other to form a complete ring-shaped cutting blade.

[0023] Reference Figure 3 and Figure 4 It also includes guide blocks 11. Guide grooves 10 are symmetrically opened on the left and right sides of the rear side of the rotating arc plate 7. Guide blocks 11 are symmetrically connected on the left and right sides of the front side of the fixed arc plate 6. The guide blocks 11 are located in the guide grooves 10.

[0024] Reference Figure 5 and Figure 6 It also includes magnetic blocks 12, and magnetic blocks 12 are connected in the guide grooves 10. The guide blocks 11 are made of iron.

[0025] Reference Figure 2 It also includes rubber blocks 13. Rubber blocks 13 are connected to both the left and right sides of the upper rear side of the rotating arc plate 7. The rear side of the rubber blocks 13 is in contact with the front side of the fixed arc plate 6.

[0026] The worker grasps handle 2 and brings the arc-shaped cutting block 9 into contact with the ground. Then, the motor 4 is started. The output shaft of motor 4 drives the mounting block 5 to rotate, which in turn drives the fixed arc-shaped plate 6 and the rotating arc-shaped plate 7 to rotate, drilling them into the soil. Soil enters the fixed arc-shaped plate 6 and the rotating arc-shaped plate 7 for soil sampling. The fixed arc-shaped plate 6 and the rotating arc-shaped plate 7 can also drive the arc-shaped cutting block 9 to rotate, allowing them to penetrate the soil more effectively. After sampling, the fixed arc-shaped plate 6 and the rotating arc-shaped plate 7 are pulled out of the soil. The device is then lowered with the rotating arc-shaped plate 7 facing upwards. The bolts on the connecting block 8 are removed, loosening the rotating arc-shaped plate 7. The worker then rotates the rotating arc-shaped plate 7 upwards, thus opening the hole. 7 separates from the fixed arc plate 6, and the rubber block 13 contacts the fixed arc plate 6 to avoid hard friction between the rotating arc plate 7 and the fixed arc plate 6, thus preventing wear on the rotating arc plate 7 and the fixed arc plate 6. At this time, the soil is completely retained in the fixed arc plate 6, so that each layer of soil can be accurately distinguished for testing and analysis of soil at different depths. The fixed arc plate 6 has scale lines, which can more accurately determine the soil at different depths. After the staff removes all the soil from the fixed arc plate 6, they rotate the rotating arc plate 7 downwards to close the rotating arc plate 7 and the fixed arc plate 6. The guide block 11 will be inserted into the guide groove 10, and the magnetic block 12 will hold the guide block 11. The guide block 11 can guide the rotating arc plate 7 to prevent the position of the rotating arc plate 7 from shifting and improve the stability of the rotating arc plate 7.
