Description

Technical Field

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

[0002] In the field of engineering construction, soil investigation is a key link to ensure the safe and stable progress of projects. Its core lies in obtaining soil samples at different depths to analyze key indicators such as the physical properties, chemical composition, and bearing capacity of the soil, providing important basis for foundation design, foundation construction, and subsequent engineering decisions.

[0003] Traditional sampling equipment often struggles to achieve precise and independent sampling of soil at different depths. Most devices mix soil from different depths together during the sampling process, making it impossible to accurately distinguish the characteristics of soil at each depth during subsequent analysis, thus affecting the accuracy of the survey results. Therefore, it is necessary to design a sampling device for engineering construction surveys to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a sampling device for engineering construction surveys to solve the problems mentioned in the background art.

[0006] The top of the rotating rod is connected to the output end of the servo motor, and the servo motor drives the rotating rod and the auger plate to rotate.

[0007] Preferably, the connector includes support blocks and bolts. Each pair of support blocks is circumferentially installed at the upper and lower ends of each sampling tube. Multiple sets of bolts are threaded between two sets of support blocks to connect multiple sampling tubes together.

[0008] Preferably, an external threaded block is installed at the top of the top sampling tube, and a support seat is installed at the top of the inner part of the placement groove, with the external threaded block threadedly connected to the support seat.

[0009] Preferably, a scraper is installed on the top outer side of the topmost sampling tube, which scrapes excess soil out of the placement trough as the scraper moves within the placement trough.

[0010] Preferably, four sets of triangular drill plates are installed in a ring at the bottom of the rotating rod.

[0011] Preferably, pull rods are installed at both ends of the top of the servo motor, and pulling the two sets of pull rods supports the servo motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By splicing two sets of sampling tubes together, with the support blocks installed on the outside of the sampling tubes overlapping, and threading bolts between the two overlapping support blocks, multiple sets of sampling tubes are connected together. The connected sampling tubes are then threaded into the placement groove. The servo motor is turned on, and the servo motor drives the rotating rod to rotate. The auger plate installed on the outside of the rotating rod moves the rotating rod into the soil. At the same time, the soil at the middle of the rotating rod is squeezed into the sampling tube. After sampling, the sampling tube is removed from the placement groove. By dismantling multiple sets of sampling tubes, soil at different depths can be observed individually.

[0014] 2. By connecting multiple sampling tubes together, rotating the sampling tube will thread the external threaded block installed on the top of the top sampling tube into the support seat installed on the top of the placement groove, thus fixing the sampling tube in the placement groove. Conversely, the sampling tube can be removed. The scraper installed on the top of the top sampling tube will scrape away the soil remaining in the placement groove when the sampling tube is removed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please refer to Figure 1-5 As shown, this utility model provides a sampling device for engineering construction survey, including a rotating rod 1 and a servo motor 11. A screw conveyor plate 2 is installed on the outside of the rotating rod 1, and a placement groove 4 is opened inside the rotating rod 1. Multiple sets of sampling tubes 5 are detachably connected inside the placement groove 4, and connecting parts are provided between the multiple sets of sampling tubes 5.

[0024] The top of the rotating rod 1 is connected to the output end of the servo motor 11, and the servo motor 11 drives the rotating rod 1 and the auger plate 2 to rotate.

[0025] Specifically, multiple sets of sampling tubes 5 are connected by connectors between the sampling tubes 5. The connected sampling tubes 5 are threaded into the placement groove 4. The servo motor 11 is turned on, and the servo motor 11 drives the rotating rod 1 to rotate. The auger plate 2 installed on the outside of the rotating rod 1 moves the rotating rod 1 into the soil. At the same time, the soil at the middle end of the rotating rod 1 is squeezed into the sampling tube 5. The sampling tube 5 after sampling is taken out from the placement groove 4. The multiple sets of sampling tubes 5 are removed by using connectors, so that soil at different depths can be observed individually.

[0026] The connector includes support blocks 8 and bolts 9. Each pair of support blocks 8 are installed in a ring at the upper and lower ends of each sampling tube 5. Multiple bolts 9 are threaded between two sets of support blocks 8 to connect multiple sampling tubes 5 together. By splicing two sets of sampling tubes 5 together, and with the support blocks 8 installed on the outside of the sampling tubes 5 overlapping, the bolts 9 are threaded between the two overlapping support blocks 8, so that multiple sampling tubes 5 are connected together.

[0027] Among them: the top of the top sampling tube 5 is equipped with an external threaded block 6, and the top of the inner end of the placement groove 4 is equipped with a support seat 7, and the external threaded block 6 is threadedly connected to the support seat 7. By connecting multiple sets of sampling tubes 5 together, rotating the sampling tube 5 will thread the external threaded block 6 installed on the top of the top sampling tube 5 into the support seat 7 installed on the top of the placement groove 4, so that the sampling tube 5 is fixed in the placement groove 4. Otherwise, the sampling tube 5 can be taken out.

[0028] Among them: a scraper 10 is installed on the outer side of the top of the top sampling tube 5. As the scraper 10 moves in the placement trough 4, it scrapes the excess soil out of the placement trough 4. By using the scraper 5 installed on the top of the top sampling tube 5, when the sampling tube 5 is taken out of the placement trough 4, the scraper 10 scrapes away the soil remaining in the placement trough 4.

[0029] Among them, four sets of triangular drilling plates 3 are installed in a ring at the bottom of the rotating rod 1. By installing four sets of triangular rotating plates 3 in a ring at the bottom of the rotating rod 1, the efficiency of drilling soil is improved, and it can also penetrate harder objects in the soil.

[0030] Among them: the top two ends of the servo motor 11 are respectively equipped with pull rods 12. Pulling the two sets of pull rods 12 supports the servo motor 11. By pulling the two sets of pull rods 12, the servo motor 11 is supported, and the supporting force of the rotating rod 1 and the auger plate 2 on the soil drilling is controlled at the same time.

[0031] Working Principle: This utility model provides a sampling device for engineering construction survey. In use, multiple sets of sampling tubes 5 are connected together. Rotating the sampling tube 5 threads the external threaded block 6 installed on the top of the top sampling tube 5 into the support seat 7 installed on the top of the placement groove 4, thus fixing the sampling tube 5 in the placement groove 4. The servo motor 11 is then turned on, driving the rotating rod 1 to rotate. The auger plate 2 installed on the outside of the rotating rod 1 moves the rotating rod 1 into the soil, simultaneously squeezing the soil at the middle of the rotating rod 1 into the sampling tube 5. After sampling, the sampling tube 5 is removed from the placement groove 4. By dismantling the multiple sets of sampling tubes 5, soil at different depths can be observed individually.
