Description

Technical Field

[0001] This utility model belongs to the technical field of soil sampling devices, specifically relating to a sampling device for sandy soil in construction land. Background Technology

[0002] A construction site sandy soil sampler is a tool specifically designed for collecting samples of sandy soil within construction site areas. Its design must accommodate the characteristics of sandy soils—coarse particles, loose structure, and easy leaching—to ensure the collection of representative and complete soil samples, providing fundamental data for soil property analysis, engineering geological surveys, and other purposes.

[0003] The sandy soil sampler for construction sites has an internal movable push rod that allows for easy sample removal after sampling. However, this push rod moves upwards as the sampling depth increases. To ensure proper sampling, the sampler instinctively adjusts their posture to avoid interfering with the push rod's ascent. However, this posture adjustment makes the overall operation less convenient and comfortable. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for sandy soil in construction sites, aiming to solve the problem that during the sampling process, the push rod continuously moves upwards as the sampling depth increases. To ensure normal sampling operations, sampling personnel subconsciously adjust their posture to prevent interference with the upward movement of the push rod. However, adjusting posture makes the overall operation less convenient and comfortable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for sandy soil in construction land, comprising a sampling bucket, a connecting rod threadedly connected to the top of the sampling bucket, an inner rod movably inserted into the top of the connecting rod, and the bottom of the inner rod movably inserted into the interior of the connecting rod;

[0006] The internal connecting rods of the sampling hopper are connected. A pusher plate is movably installed inside the sampling hopper. A movable rod is fixedly installed on the top outer wall of the pusher plate. The other end of the movable rod is movably inserted into the inside of the connecting rod. One end of the connecting rod has an inner cavity, and the end of the inner rod located inside the connecting rod is movably inserted into the inner cavity.

[0007] In order to fix the part of the inner rod near the bottom in the inner cavity, as a sampling device for sandy soil in construction land according to this utility model, preferably, a positioning plate is welded to one end of the inner rod inside the inner cavity, and a movable sleeve is movably sleeved on the outer wall of the inner rod above the positioning plate, and the outer wall of the movable sleeve is provided with a threaded structure.

[0008] In order to enable the inner rod to rotate synchronously with the moving sleeve when it rotates, as a construction land sandy soil sampling device of this utility model, preferably, a threaded inner wall is provided on the inner wall above the transverse midline of the inner cavity, the threaded inner wall is adapted to the threaded structure on the moving sleeve, and a notch is provided on the outer wall on both sides of the bottom opening of the moving sleeve.

[0009] A protruding post is welded to each of the two outer walls of the inner rod below the moving sleeve, and the size of the protruding post is adapted to the size of the notch.

[0010] In order to enable the outer wall of the thread to form a fixed structure with the inner cavity, thereby giving the inner rod a double-layer fixed structure in the inner cavity and improving the firmness of the inner rod and the movable rod after they are fixed together, as a construction land sandy soil sampling device of this utility model, preferably, a fixed sleeve is fixedly installed on the inner wall of the inner cavity near the top, and the inner wall of the fixed sleeve is provided with a threaded structure.

[0011] A threaded outer wall is provided on the outer wall at the transverse midline of the inner rod, and the size of the threaded outer wall is adapted to the thread structure on the inner wall of the fixed sleeve.

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

[0013] After the sampling hopper completes sampling in the sandy soil of the construction site, the pusher plate will push the movable rod upward during the sampling process. As the movable rod moves upward, it will also cause the inner cavity to move upward. This upward movement will follow the outer wall of the inner lifting rod. During this process, the movable rod will not cause the inner lifting rod to move upward. In this way, when the sampling personnel are sampling, the inner lifting rod will not cause inconvenience to the sampling personnel due to its upward movement, thereby improving the comfort of using the device.

[0023] 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.

[0024] Please see Figure 1-7 The present invention provides the following technical solution: a sampling device for sandy soil of construction land, including a sampling bucket 1, a connecting rod 2 threadedly connected to the top of the sampling bucket 1, an inner rod 3 movably inserted into the top of the connecting rod 2, and the bottom of the inner rod 3 movably inserted into the inside of the connecting rod 2.

[0025] At the construction site, the sampling bucket 1 is inserted into the sandy soil. Then, the sampling personnel rotate and press the connecting rod 2 to move the sampling bucket 1 further into the sandy soil, thereby collecting the sandy soil into the sampling bucket 1 and completing the sampling operation of the sandy soil at the construction site.

[0026] The internal connecting rod 2 of the sampling hopper 1 is connected. The pushing plate 4 is movably installed inside the sampling hopper 1. The movable rod 5 is fixedly installed on the top outer wall of the pushing plate 4. The other end of the movable rod 5 is movably inserted into the inside of the connecting rod 2. One end of the connecting rod 2 has an inner cavity 51. The end of the inner rod 3 located inside the connecting rod 2 is movably inserted into the inner cavity 51.

[0027] Preferably, a positioning plate 6 is welded to one end of the inner rod 3 inside the inner cavity 51, and a movable sleeve 8 is movably sleeved on the outer wall of the inner rod 3 above the positioning plate 6, and the outer wall of the movable sleeve 8 is provided with a threaded structure.

[0028] The outer wall of the positioning disc 6 is in contact with the inner wall of the inner cavity 51. During use, the positioning disc 6 moves along with the inner rod 3.

[0029] Preferably, a threaded inner wall 52 is provided on the inner wall above the transverse midline of the inner cavity 51. The threaded inner wall 52 is adapted to the threaded structure on the moving sleeve 8. A notch 81 is provided on the outer wall on both sides of the bottom opening of the moving sleeve 8.

[0030] A protruding post 7 is welded to each of the two outer walls of the inner rod 3 below the moving sleeve 8. The size of the protruding post 7 is matched with the size of the notch 81.

[0031] Preferably, a fixed sleeve 53 is fixedly installed on the inner wall of the inner cavity 51 near the top, and the inner wall of the fixed sleeve 53 is provided with a threaded structure.

[0032] In practical use, when it is necessary to remove the sandy soil sample from inside the sampling hopper 1, first pull the top of the inner rod 3 upward. When the inner rod 3 moves upward, it will drive the protruding posts 7 on both sides to move upward simultaneously. When the protruding posts 7 align with the notch 81 at the bottom of the moving sleeve 8, the inner rod 3 will then drive the moving sleeve 8 to move downward simultaneously through the protruding posts 7.

[0033] When the movable sleeve 8 moves to the bottom of the threaded inner wall 52, the top of the threaded outer wall 31 also moves to the bottom of the fixed sleeve 53. Rotating the inner rod 3 causes the movable sleeve 8 to rotate via the protrusion 7, thus locking the movable sleeve 8 into contact with the threaded inner wall 52. Simultaneously, the threaded outer wall 31 also locks into the internal thread of the fixed sleeve 53. This securely connects the inner rod 3 and the movable rod 5 together.

[0034] Next, pushing the inner rod 3 will drive the movable rod 5 to move. When the movable rod 5 moves, it will drive the pusher plate 4 to move inside the sampling hopper 1, so that the sandy soil sample in the sampling hopper 1 can be taken out.

[0035] Preferably, a threaded outer wall 31 is provided on the outer wall at the transverse midline of the inner rod 3, and the size of the threaded outer wall 31 is adapted to the thread structure on the inner wall of the fixed sleeve 53.

[0036] In practical use, during the sampling operation of sandy soil in construction sites, as the sampling bucket 1 is inserted into the sandy soil, the pusher plate 4, through the horizontal pushing force and the vertical upward force, will further push the movable rod 5 to rise steadily along the predetermined track when the pusher plate 4 moves.

[0037] The movable rod 5 has an inner cavity 51, which forms a nested fit with the inner lifting rod 3. When the movable rod 5 is driven upward by the pusher plate 4, the inner cavity 51 moves upward synchronously along the outer wall of the inner lifting rod 3.

[0038] This structure ensures that the inner rod 3 remains stationary throughout the entire sampling process, preventing the top of the inner rod 3 from moving upwards above the connecting rod 2. This eliminates the need for sampling personnel to consciously avoid certain positions, thus improving the ease of use of the device.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
