Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically a soil sampling device for building construction sites. Background Technology
[0002] Construction engineering refers to engineering entities formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment, to meet people's needs for production, residence, learning, and public activities. During the construction of construction projects, sampling devices are needed to sample and test the soil in the construction site.
[0003] According to the search, Chinese patent document, publication number CN215640254U, discloses a soil sampling device for construction engineering. Its rotational design can not only save effort during sampling but also improve sampling efficiency. However, after sampling, the sampled soil gets stuck in the sampling tube and needs to be removed manually with other tools. This can easily leave soil residue on the inner wall of the sampling tube. If the residual soil is not cleaned in time, it will mix with the soil sampled later, causing contamination of the soil sampled later. Therefore, it needs to be improved. Utility Model Content

[0014] Beneficial effects:
[0015] Compared with existing technologies, this soil sampling device for construction sites has the following advantages:
[0016] I. This utility model, through the setting of a rotating rod, threaded cylinder, screw, sampling cylinder, insert teeth, limiting rod, limiting block, telescopic rod, scraper, push rod, and handle, allows the mounting frame to be fixed at the sampling location. The rotating rod can be used to rotate the screw within the threaded cylinder. Because the limiting rod is inserted into the limiting hole of the mounting frame, the sampling cylinder is pressed down without rotating simultaneously, causing the insert teeth and sampling cylinder to insert into the soil for sampling. After sampling, the sampling cylinder can be lifted out of the soil by rotating the rotating rod in the opposite direction. After lifting, the push rod can be pressed down by holding the handle or stepping on the handle, causing the movable rod of the telescopic rod to extend and drive the scraper to push the sampled soil out of the sampling cylinder for unloading. The scraper can also scrape the inner wall of the sampling cylinder, making it less likely for soil to remain on the inner wall.
[0017] II. This utility model, through the setting of connecting seat one, connecting seat two, support rod, support plate and threaded rivets, allows the support rod to be adjusted through the setting of connecting seat one and connecting seat two when soil sampling is required, so that the support plate can be placed in a suitable position. Then, by rotating the threaded rivets one by one with a power tool, they are drilled into the soil for fixation, so that the mounting frame can be stably supported and fixed.
[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] 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.
[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a soil sampling device for a construction site, including a sampling cylinder 1, an opening through the bottom surface of the sampling cylinder 1, and several insert teeth 6 fixedly installed on the outer edge of the opening, a lifting component on the top surface of the sampling cylinder 1, a limiting component on the top surface of the sampling cylinder 1, and four circular openings through the top surface of the sampling cylinder 1, with a unloading component on the inner wall of the circular openings.
[0026] The lifting assembly includes a mounting frame 2, a threaded cylinder 3, a screw 4, and a rotating rod 5. A bushing is fixedly installed on the top surface of the sampling cylinder 1, and a screw 4 is sleeved on the inner wall of the bushing. The threaded cylinder 3 is threadedly connected to the arc-shaped surface of the screw 4. The mounting frame 2 is fixedly installed on the arc-shaped surface of the threaded cylinder 3. An installation port is provided through the upper end of the arc-shaped surface of the screw 4, and a rotating rod 5 is fixedly installed on the inner wall of the installation port. A support assembly is provided on the arc-shaped surface of the mounting frame 2, and limit holes are provided through the top two ends of the mounting frame 2.
[0027] According to the overall structure of the device, adjust the support rod 15 so that the support plate 17 can be placed in a suitable position. Then, use a power tool to rotate the threaded rivets 18 one by one to drill into the soil and fix them, thus fixing the mounting frame 2. Then, rotate the rotating rod 5 to make the screw 4 rotate in the threaded cylinder 3. Since the limiting rod 7 is inserted into the limiting hole of the mounting frame 2, the sampling cylinder 1 is pressed down without rotating together, so that the insert 6 and the sampling cylinder 1 are inserted into the soil for sampling. After sampling, the sampling cylinder 1 is lifted out of the soil by rotating the rotating rod 5 in the opposite direction. After being lifted out, the push rod 12 is pressed down by holding the handle 13 or stepping on the handle 13, so that the movable rod of the telescopic rod 9 extends out, driving the scraper 11 to push the sampled soil in the sampling cylinder 1 out of the sampling cylinder 1 for unloading. The scraper 11 can also scrape the inner wall of the sampling cylinder 1, so that soil is not easily left on the inner wall of the sampling cylinder 1.
[0028] like Figure 2 As shown, the support assembly includes a first connecting seat 14, a support rod 15, a second connecting seat 16, and a support plate 17. The first connecting seat 14 is fixedly installed at three ends of the arc-shaped surface of the mounting bracket 2. A connecting shaft is fixedly installed on the inner wall of the first connecting seat 14. The second connecting seat 16 is fixedly installed on the top surface of the support plate 17, and a connecting shaft is fixedly connected to the inner wall of the second connecting seat 16. Sleeves are fixedly installed at both ends of the support rod 15. One sleeve of the support rod 15 is sleeved with the connecting shaft of the first connecting seat 14, and the other sleeve of the support rod 15 is sleeved with the connecting shaft of the second connecting seat 16. An opening is provided through the top surface of the support plate 17, and the inner wall of the opening is threaded. A threaded rivet 18 is threadedly connected to the inner wall of the opening of the support plate 17.
[0029] By using the connecting seat 14, support rod 15, connecting seat 2 16, support plate 17, and threaded rivet 18, the support rod 15 can be adjusted, allowing the support plate 17 to be placed in a suitable position. Then, by using a power tool to rotate the threaded rivet 18, it is drilled into the soil for fixation, so that the mounting frame 2 can be stably supported and fixed.
[0030] like Figure 3As shown, the limiting component includes a limiting rod 7 and a limiting block 8. The limiting rod 7 is fixedly installed at both ends of the top surface of the sampling cylinder 1. The limiting rod 7 passes through the limiting hole of the mounting frame 2, and the limiting block 8 is fixedly connected to the top surface. The limiting block 8 is larger than the limiting hole of the mounting frame 2, and the limiting rod 7 fits into the inner wall of the limiting hole of the mounting frame 2.
[0031] By setting the limiting rod 7 and the limiting block 8, the sampling cylinder 1 will not rotate with the screw 4 as the limiting rod 7 passes through the limiting hole of the mounting frame 2, and the limiting block 8 can prevent the limiting rod 7 from coming out of the limiting hole of the mounting frame 2.
[0032] like Figure 4 As shown, the unloading assembly includes a telescopic rod 9 and a scraper 11. The telescopic rod 9 is fixedly installed in the circular opening on the top surface of the sampling cylinder 1. The scraper 11 is fixedly connected to the bottom surface of the movable rod of the telescopic rod 9. The scraper 11 is in contact with the inner wall of the sampling cylinder 1. An opening is provided through the top surface of the outer cylinder of the telescopic rod 9. A drive assembly is connected to the top surface of the movable rod of the telescopic rod 9. The drive assembly includes a handle 13 and a push rod 12. The push rod 12 is fixedly installed on the top surface of the movable rod of the telescopic rod 9. A handle 13 is fixedly connected between each pair of push rods 12. The handle 13 is L-shaped.
[0033] The telescopic rod 9, scraper 11, push rod 12 and handle 13 are designed so that the push rod 12 can be pressed down by holding the handle 13 or stepping on the handle 13, so that the movable rod of the telescopic rod 9 can be extended, driving the scraper 11 to push the soil sampled in the sampling tube 1 out of the sampling tube 1 for unloading. The scraper 11 can also scrape the inner wall of the sampling tube 1, so that soil is not easily left on the inner wall of the sampling tube 1.
[0034] Working principle: By adjusting the support rod 15, the support plate 17 can be placed in a suitable position. Then, by using a power tool, the threaded rivets 18 are rotated one by one to drill into the soil and fix them, thus fixing the mounting frame 2. Then, by rotating the rotating rod 5, the screw 4 rotates in the threaded cylinder 3. Since the limiting rod 7 is inserted into the limiting hole of the mounting frame 2, the sampling cylinder 1 is pressed down without rotating together, so that the insert 6 and the sampling cylinder 1 are inserted into the soil for sampling. After sampling, the sampling cylinder 1 is lifted out of the soil by rotating the rotating rod 5 in the opposite direction. After being lifted out, the push rod 12 is pressed down by holding the handle 13 or stepping on the handle 13, so that the movable rod of the telescopic rod 9 extends, driving the scraper 11 to push the sampled soil in the sampling cylinder 1 out of the sampling cylinder 1 for unloading. The scraper 11 can also scrape the inner wall of the sampling cylinder 1.
