[0004] The aforementioned patent provides stable support for the soil sampler by setting up a mounting frame. Since the soil sampler needs to be used in various different soil sampling locations, and some sampling areas are rugged and narrow, the existing soil sampler has a large and heavy stable structure, making it difficult to carry. Utility Model Content

[0005] The purpose of this invention is to provide a soil sampler with a stable structure to solve the problem mentioned in the background art that the stable structure of current soil samplers on the market is too large and difficult to carry.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soil sampler with a stable structure, comprising a support frame and a sampling tube, wherein the sampling tube is provided at the bottom end of the support frame, the sampling tube is provided with a locking mechanism inside, a fixing ring is welded to the inner wall of the sampling tube, and a bearing seat is welded to both sides of the bottom end of the support frame located on the sampling tube, a connecting plate is connected to the inner side of the bearing seat through a rotating shaft, and a first sliding groove is provided on the inner side of the connecting plate.

[0007] Preferably, a sliding block is provided on the inner side of the connecting plate, a fixed pile rod is welded to the bottom end of the sliding block, a second sliding groove is provided inside the fixed pile rod, and a connecting shaft passing through the second sliding groove is provided on the inner side of the first sliding groove.

[0008] Preferably, handles are welded to the top of both sides of the support frame, and a fixing frame is welded to the top of the support frame inside the two sets of handles. A motor is installed on the inner side of the fixing frame by bolts.

[0009] Preferably, the sampling tube has an engagement groove extending to the outside inside, and a scale is welded to the outer wall of the sampling tube.

[0011] Preferably, the engaging mechanism includes a connecting chamber, a fixing rod, a limiting rod, and a spring. The bottom end of the motor is located inside the sampling tube and is connected to the connecting chamber by bolts. Two sets of fixing rods are welded inside the connecting chamber. One end of each set of fixing rods is welded with a limiting rod extending to the outside of the connecting chamber. A spring is sleeved on the outer wall of the fixing rod at one end of the limiting rod.

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

[0013] 1. When using this soil sampler, the bottom end of the sampling tube is inserted into the soil. Then, the connecting plate is rotated upwards via the rotating shaft. After the fixed stake rod rotates via the connecting shaft, one end of the fixed stake rod is inserted into the ground. The fixed stake rod is fixed to the ground by striking the sliding block with a hammer. The handle, support frame, and motor drive the locking mechanism and the sampling tube to rotate and descend, allowing the sampling tube to enter the soil and sample the soil. The sampling tube takes a sample from the soil. The stable structure of the soil sampler is foldable, which is achieved through the shaft seat, connecting plate, first sliding groove, sliding block, fixed stake rod, second sliding groove, connecting shaft, and sampling tube. This allows the soil sampler to be placed stably while saving storage space, and the soil sampler is easy to carry and transport.

[0014] 2. When the soil sample in the soil sampler needs to be removed, the limiting rod is moved by pushing the push rod, so that the limiting rod cannot engage with the locking groove, and the locking mechanism cannot limit the sampling tube. The sampling tube is then removed from the outer wall of the locking mechanism, and the sample inside the sampling tube is poured out. By setting the locking groove, locking mechanism, fixing ring, baffle and shaft, the soil sample can be removed completely, and the structure of the soil sample is not easily damaged.

[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] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a soil sampler with a stable structure, including a support frame 1 and a sampling tube 2. The sampling tube 2 is provided at the bottom end of the support frame 1. The sampling tube 2 is provided with a locking mechanism 3 inside. A fixing ring 4 is welded to the inner wall of the sampling tube 2. The bottom end of the support frame 1 is located on both sides of the sampling tube 2 and a bearing 5 is welded thereon. A connecting plate 501 is connected to the inner side of the bearing 5 through a rotating shaft. A first sliding groove 502 is opened on the inner side of the connecting plate 501.

[0023] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It is known that a sliding block 503 is provided on the inner side of the connecting plate 501, and a fixed pile rod 504 is welded to the bottom end of the sliding block 503. A second sliding groove 505 is provided inside the fixed pile rod 504. A connecting shaft 506 is provided on the inner side of the first sliding groove 502, which passes through the second sliding groove 505. The outer wall of the connecting shaft 506 is slidably connected to the inner wall of the second sliding groove 505, the outer wall of the connecting shaft 506 is slidably connected to the inner wall of the first sliding groove 502, and the outer wall of the sliding block 503 is slidably connected to the inner wall of the connecting plate 501.

[0024] In practice, when the soil sampler needs to take stable samples, the soil sampler is placed vertically on the ground, the bottom end of the sampling tube 2 is inserted into the soil, and the connecting plate 501 is rotated upward by the rotating shaft. The rotation of the connecting plate 501 drives the first sliding groove 502, the sliding block 503, the fixed pile rod 504, the second sliding groove 505 and the connecting shaft 506 to move. The fixed pile rod 504 is rotated by the connecting shaft 506, and one end of the fixed pile rod 504 is inserted into the ground. The sliding block 503 is hammered with a hammer, causing the sliding block 503 to descend. The descent of the sliding block 503 fixes the fixed pile rod 504 to the ground.

[0025] The operator holds handle 101 and starts motor 103. The output of motor 103 drives the locking mechanism 3 and sampling tube 2 to rotate. The operator pushes handle 101, support frame 1, shaft seat 5, connecting plate 501 and sampling tube 2 to descend. The descent of connecting plate 501 causes the first sliding groove 502 and connecting shaft 506 to descend, allowing connecting shaft 506 to slide against the inner wall of the second sliding groove 505, so that sampling tube 2 enters the soil and samples the soil. This is achieved by setting up shaft seat 5, connecting plate 501, and first sliding groove 505. 02. The sliding block 503, the fixed pile rod 504, the second sliding groove 505, and the connecting shaft 506 enable the soil sampler to be placed stably, making the soil sampler more stable during use. At the same time, the shaft seat 5, the connecting plate 501, the first sliding groove 502, the sliding block 503, the fixed pile rod 504, the second sliding groove 505, and the connecting shaft 506 can be folded with the sampling tube 2. By setting the stable structure of the soil sampler to a foldable structure, the soil sampler can be placed stably while saving storage space, making the soil sampler easy to carry and transport.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that handles 101 are welded to the top of both sides of the support frame 1. A fixing frame 102 is welded to the top of the support frame 1 inside the two sets of handles 101. A motor 103 is installed on the inner side of the fixing frame 102 by bolts. The output end of the motor 103 is connected to the locking mechanism 3.

[0027] In practice, the motor 103 is started, and the output end of the motor 103 drives the locking mechanism 3 and the sampling tube 2 to rotate.

[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It can be seen that the sampling tube 2 has an engagement groove 201 extending to the outside, and a scale 202 is welded to the outer wall of the sampling tube 2.

[0029] In practice, the depth of soil sample taken by the soil sampler can be observed by setting a scale 202.

[0030] See Figure 2 , Figure 3 and Figure 5 It can be seen that a baffle 401 is welded to the top of the fixed ring 4, and a shaft bracket 402 is connected to the inner side of the baffle 401 through a rotating shaft. The baffle 401 and the shaft bracket 402 are connected through a rotating shaft.

[0031] In practice, when the soil sampler takes a sample, the sampling tube 2 gradually enters the soil. The soil pushes the shaft frame 402 to rotate through the baffle 401 and the rotating shaft. The sampled soil enters the interior of the sampling tube 2 through the fixing ring 4 and the shaft frame 402. When the sampling tube 2 is pulled out, the soil inside the shaft frame 402 is affected by gravity and falls, pushing the shaft frame 402. The shaft frame 402 rotates to one side of the fixing ring 4 through the baffle 401 and the rotating shaft, and the shaft frame 402 blocks the sampled soil.

[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 4 It is known that the locking mechanism 3 includes a connecting chamber 301, a fixing rod 302, a limiting rod 303, and a spring 304. The bottom end of the motor 103 is located inside the sampling tube 2 and is connected to the connecting chamber 301 by bolts. Two sets of fixing rods 302 are welded inside the connecting chamber 301. One end of each set of fixing rods 302 is welded with a limiting rod 303 extending to the outside of the connecting chamber 301. The outer wall of the fixing rod 302 is fitted with a spring 304 at one end of the limiting rod 303. The inner wall of the limiting rod 303 is slidably connected to the outer wall of the fixing rod 302. One end of the limiting rod 303 is locked and connected to the inside of the locking groove 201.

[0033] In practice, when it is necessary to remove the sample from the soil sampler, a push rod is inserted into the locking groove 201. The push rod pushes the limiting rod 303 to move. The limiting rod 303 slides on the outer wall of the fixed rod 302. The limiting rod 303 pushes the spring 304 to compress and deform. The limiting rod 303 moves, so that one end of the limiting rod 303 can no longer limit the locking groove 201. The sampling tube 2 is separated from the locking mechanism 3, and the soil sample in the sampling tube 2 is poured out. By setting the locking groove 201, locking mechanism 3, fixing ring 4, baffle 401 and shaft frame 402, the soil sample can be completely removed, which is convenient for the operator to extract the required soil sample and makes the structure of the soil sample less likely to be damaged.

[0034] In summary: When using the soil sampler, place it vertically on the ground and insert the bottom end of the sampling tube 2 into the soil. The soil sampler is stably supported by the bearing 5, connecting plate 501, first sliding groove 502, sliding block 503, fixed pile rod 504, second sliding groove 505, and connecting shaft 506. Hold the handle 101 and start the motor 103. The output end of the motor 103 drives the locking mechanism 3 and the sampling tube 2 to rotate. The operator pushes the handle 101, support frame 1, bearing 5, connecting plate 501, and sampling tube 2 to lower them, so that the sampling tube 2 enters the soil. The soil inside the sampling tube 2 is limited by the fixing ring 4, baffle 401, and bearing 402, so that the soil can be sampled completely.

[0035] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
