[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0021] Embodiment one
[0022] Please refer to Figures 1-4 The present application provides the following technical scheme: a core placing device in soil investigation process, comprising a fixed box body 1 and a placing rack 2 assembled in the fixed box body 1, a placing groove 3 is formed in the top surface of the placing rack 2, a sealing cover 4 is detachably connected to the top end of the fixed box body 1, a threaded rod 5 is connected to the inside of both ends of the fixed box body 1, a bearing 6 is connected to the end of the threaded rod 5, a threaded sleeve 7 is threadedly connected to the surface of the threaded rod 5, and a placing box 13 is connected to the front end of the fixed box body 1.
[0023] In the preferred embodiment, the outer side wall of the threaded sleeve 7 is connected to both ends of the placing rack 2, and the placing rack 2 is threadedly connected between the threaded sleeve 7 and the threaded rod 5.
[0024] In the preferred embodiment, the threaded rod 5 is rotatably connected between the bearing 6 and the fixed box body 1.
[0025] In the embodiment, first, during soil investigation process, the survey personnel uses special equipment to take out the core from the soil, and then places it in the placing groove 3 on the top of the placing rack 2. Then, the staff manually rotates the threaded rod 5 clockwise, so that it rotates along the inner ring of the bearing 6; the threaded sleeve 7 moves along the threads on the surface of the threaded rod 5, thereby driving the placing rack 2 to descend into the fixed box body 1. Conversely, if the placing rack 2 needs to be raised, it can be rotated counterclockwise. This design facilitates manual carrying of the placing device to different areas, placing the soil cores taken from different areas, facilitating flexible operation of the lifting of the placing rack 2, avoiding the inconvenience of placing in the inside of the fixed box body 1, and affecting the integrity of the core placement. Then, through the connection of the sealing cover 4 and the fixed box body 1, a sealed environment is formed, ensuring that the core is not affected by external environmental factors (such as humidity, temperature, dust, etc.), and maintaining its original purity.
[0026] It is worth noting that: the use of the placing box 13 can insert the cards recording the cores of different regions in the placing box 13, which facilitates the differentiation of the cores on the placing rack 2.
[0027] Embodiment two
[0028] Please refer to Figures 1-4The inside of the placing groove 3 is provided with a fixed plate 9, the top end of the fixed plate 9 is connected with a mounting rack 8, and the top end of the mounting rack 8 is screwedly connected with an extruding bolt 12 on one side.
[0029] Preferably, the placing rack 2 is provided with a sliding groove 10 at both ends, and the sliding groove 10 is slidably connected with a sliding block 11.
[0030] Preferably, the mounting rack 8 is detachably and fixedly connected with the placing rack 2 through the extruding bolt 12.
[0031] Preferably, the sliding block 11 is matched with the sliding groove 10 in a "convex" shape, and the top end of the sliding block 11 is connected with the mounting rack 8.
[0032] In the embodiment, according to the description of the first embodiment, after the core is properly placed in the placing groove 3 of the placing rack 2, the extruding bolt 12 is manually rotated to release the extruding and fixing of the mounting rack 8. Then, the mounting rack 8 is manually used to push the fixed plate 9 to slide in the placing groove 3, at the same time, the mounting rack 8 drives the sliding block 11 to move along the sliding groove 10, then the fixed plate 9 is close to the position of the two ends of the core to limit the core, and then the extruding bolt 12 is rotated again to extrude and fix the mounting rack 8 with the placing rack 2. Thus, the core is prevented from loosening in the placing groove 3. This step not only ensures the stability of the core, but also ensures the consistency of the length of the core.
[0033] Finally, it should be noted that the above description is only preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
