Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of soil sampling devices, and in particular to an environmental geological soil sampling device. Background Technology
[0002] Environmental geological surveys involve investigating regional geological conditions and environmental geological problems caused by natural geological processes and human activities. Therefore, soil sampling is necessary when conducting geological surveys of the surrounding environment, and the results are used to analyze the geological conditions of the area. Handheld sampling tubes are a commonly used tool in soil sampling; their portability and ease of use make them a preferred choice for field soil sampling. When using a handheld sampling tube, the appropriate sampling depth can be determined according to the sampling purpose and requirements. Hold the sampling tube and insert it vertically into the soil until the predetermined sampling depth is reached. After reaching the predetermined depth, gently rotate the sampling tube and then pull it vertically upwards to ensure the integrity of the soil sample. The inner wall of the sampling tube is generally smooth, resulting in minimal friction with the soil. During the rotation of the sampling tube, the soil inside rotates relative to the tube. When pulling the tube upwards, there is insufficient friction to prevent soil from falling out, affecting subsequent analysis of the soil sample. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an environmental geological soil sampling device, in which an anti-rotation rib is provided in the sampling chamber. When the sampling tube is rotated, the anti-rotation rib pushes the soil inside the sampling tube to rotate with the sampling tube, thus separating the soil inside the sampling tube from the soil outside the sampling tube. When the sampling tube is lifted upwards, the soil is not easily detached from the sampling tube.
[0004] An environmental geological soil sampling device according to an embodiment of the present invention includes:
[0005] A sampling tube has a sampling chamber with an open lower end, a handle at the top of the sampling tube, a threaded hole at the top of the sampling tube communicating with the sampling chamber, and an anti-rotation rib protruding from the inner wall of the sampling chamber, the length direction of the anti-rotation rib being consistent with the axial direction of the sampling tube.
[0006] A pusher block is slidably connected to the sampling chamber, and an avoidance notch is provided on the pusher block corresponding to the position of the anti-rotation rib;
[0007] A push rod is provided with an external thread, which is adapted to and connected to the threaded hole, and the push rod abuts against the push block.
[0008] An environmental geological soil sampling device according to an embodiment of the present invention has at least the following beneficial effects:
[0009] Rotate the push rod to adjust its depth into the sampling tube; hold the handle of the sampling tube and insert it vertically into the soil for sampling. Soil enters the sampling chamber, pushing the push block against the push rod until it contacts the rod. Rotate the sampling tube and then lift it vertically upwards. Continue rotating the push rod to increase its depth into the sampling tube. The push rod pushes the push block along the axial direction of the sampling tube, pushing the soil out of the sampling chamber. Because the sampling chamber has anti-rotation ribs, when the sampling tube is rotated, the anti-rotation ribs push the soil inside the sampling tube to rotate with the tube, separating the soil inside from the soil outside. When the sampling tube is lifted upwards, the soil is less likely to fall out.
[0010] According to some embodiments of the present invention, a first guide hole is provided at the top of the sampling cylinder, and a guide rod is connected to the push block, the guide rod slidingly passing through the first guide hole.

[0012] According to some embodiments of the present invention, one end of the guide rod protruding from the sampling tube is connected to a limiting block. When the push block is located at the bottom of the sampling tube, the limiting block abuts against the top of the sampling tube.
[0013] According to some embodiments of this utility model, a handwheel is connected to the end of the push rod that protrudes from the sampling tube, and rotating the handwheel can drive the push rod to rotate.
[0014] According to some embodiments of the present invention, the push block is provided with an arc-shaped groove for the push rod to extend into, and the end of the push rod near the push block is provided with an arc-shaped surface.
[0015] According to some embodiments of the present invention, the environmental geological soil sampling device further includes a guide component for fixing to the ground. The guide component includes a guide cylinder with a second guide hole, and the sampling cylinder slides through the second guide hole.
[0016] According to some embodiments of the present invention, the guide assembly further includes a plurality of first fixing claws, which are arranged in a circular array on the guide cylinder, and the end of the first fixing claw away from the guide cylinder is provided with a first protrusion for insertion into the ground.
[0017] According to some embodiments of the present invention, the guide assembly further includes a plurality of second fixing claws, which are arranged in a circular array on the guide cylinder. The second fixing claws have a second protrusion for insertion into the ground at the end away from the guide cylinder. The first fixing claw and the second fixing claw are respectively connected to the two ends of the guide cylinder along the axial direction of the guide cylinder.
[0018] According to some embodiments of the present invention, both the first fixing claw and the second fixing claw are hinged to the guide cylinder.
[0019] According to some embodiments of the present invention, four first fixing claws and four second fixing claws are provided.

[0035] Please see Figure 1 , Figure 2 and Figure 3An environmental geological soil sampling device according to an embodiment of this utility model includes a sampling cylinder 100, a pusher block 200, and a pusher rod 300. The sampling cylinder 100 has a sampling chamber 110, the lower end of which is open. A handle 120 with anti-slip grooves is provided on the top of the sampling cylinder 100. A threaded hole 130 is provided at the top of the sampling cylinder 100, communicating with the sampling chamber 110. An anti-rotation rib 140 protrudes from the inner wall of the sampling chamber 110, the length of which is aligned with the axial direction of the sampling cylinder 100. The pusher block 200 is slidably connected within the sampling chamber 110. (See reference...) Figure 4 The push block 200 has a clearance notch 210 at the position corresponding to the anti-rotation rib 140. The anti-rotation rib 140 can restrict the rotation of the push block 200, so that the push block 200 slides stably in the sampling chamber 110. The push rod 300 is provided with an external thread 310, which is adapted to and connected to the threaded hole 130. The push rod 300 abuts against the push block 200.
[0036] Rotate the push rod 300 to adjust the depth to which it is screwed into the sampling tube 100; hold the handle 120 of the sampling tube 100 and insert it vertically into the soil for sampling. The soil enters the sampling chamber 110. Push the push block 200 against the push rod 300 until the push block 200 abuts against the push rod 300; rotate the sampling tube 100 and then lift it vertically upward. Continue to rotate the push rod 300 to increase the depth to which the push rod 300 extends into the sampling tube 100. The push rod 300 pushes the push block 200 to move axially along the sampling tube 100, and the push block 200 pushes the soil out of the sampling chamber 110. Because the sampling chamber 110 is equipped with anti-rotation ribs 140, when the sampling tube 100 is rotated, the anti-rotation ribs 140 push the soil inside the sampling tube 100 to rotate with the sampling tube 100. The soil inside the sampling tube 100 is separated from the soil outside the sampling tube 100. When the sampling tube 100 is lifted upwards, the soil is not easy to fall out of the sampling tube 100.
[0037] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The sampling cylinder 100 has a first guide hole 150 at its top, and a guide rod 230 is connected to the push block 200. The guide rod 230 slides through the first guide hole 150. The lower end of the guide rod 230 is threadedly connected to the push block 200, making it easy to install and remove. The guide rod 230 on the push block 200 ensures that the push block 200 slides smoothly within the sampling chamber 110.
[0038] In some embodiments, see Figure 1 , Figure 2 and Figure 3The guide rod 230 is equipped with a scale. An indicator is located on the top of the sampling tube 100 near the guide rod 230. When the push block 200 is at the bottom of the sampling tube 100, the indicator points to the scale of 0; when the push block 200 is at the top of the sampling tube 100, the indicator points to the maximum value of the scale.
[0039] The sampling tube 100 is vertically inserted into the soil for sampling. The soil enters the sampling chamber 110, pushing the pusher 200 upward and pushing the guide rod 230 upward. The length of the guide rod 230 protruding from the sampling tube 100 increases. The sampling depth is obtained by the scale on the guide rod 230 corresponding to the top of the sampling tube 100.
[0040] In some embodiments, see Figure 1 , Figure 2 and Figure 3 One end of the guide rod 230 protruding from the sampling cylinder 100 is connected to a limiting block 231. A limiting block 231 is provided at the upper end of the guide rod 230. When the push block 200 is at the bottom of the sampling cylinder 100, the limiting block 231 just abuts against the top of the sampling cylinder 100. The limiting block 231 can prevent the guide rod 230 and the push block 200 from coming off the sampling cylinder 100.
[0041] In some embodiments, see Figure 1 , Figure 2 and Figure 3 A handwheel 320 is connected to the end of the push rod 300 that protrudes from the sampling tube 100. Rotating the handwheel 320 causes the push rod 300 to rotate, adjusting the length of the push rod 300 extending into the sampling tube 100. When rotating the handwheel 320 clockwise increases the length of the push rod 300 extending into the sampling tube 100, rotating the handwheel 320 counterclockwise decreases the length of the push rod 300 extending into the sampling tube 100.
[0042] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The push block 200 is provided with an arc-shaped groove 220 for the push rod 300 to extend into. The end of the push rod 300 near the push block 200 is provided with an arc-shaped surface. The arc-shaped groove 220 can position the push rod 300. The arc-shaped surface abutting against the arc-shaped groove 220 can increase the contact area between the push rod 300 and the push block 200, ensuring that the push block 200 is subjected to uniform force.
[0043] In some embodiments, see Figure 1 , Figure 3 and Figure 5The environmental geological soil sampling device also includes a guiding component 400, which is fixed to the ground. The guiding component 400 includes a guiding cylinder 410 with a second guiding hole 411. The sampling cylinder 100 slides through the second guiding hole 411. By setting the guiding component 400, it is ensured that the sampling cylinder 100 samples in a direction perpendicular to the ground, thereby improving the accuracy of soil sample detection and analysis.
[0044] In some embodiments, see Figure 1 , Figure 3 and Figure 5 The guide assembly 400 also includes a plurality of first fixing claws 420, which are arranged in a circular array on the guide cylinder 410. Each first fixing claw 420 has a first protrusion 421 at its end away from the guide cylinder 410. The first protrusion 421 is spike-shaped and can be inserted into the ground. The plurality of first fixing claws 420 fix the guide cylinder 410, ensuring its position is fixed and allowing it to better guide the sampling cylinder 100.
[0045] In some embodiments, see Figure 1 , Figure 3 and Figure 5 The guide assembly 400 also includes multiple second fixing claws 430, which are arranged in a circular array on the guide cylinder 410. Each second fixing claw 430 has a second protrusion 431 at its end away from the guide cylinder 410. The second protrusion 431 is spike-shaped and can be inserted into the ground. The first fixing claw 420 and the second fixing claw 430 are respectively connected to both ends of the guide cylinder 410 along its axial direction. The first fixing claw 420 and the second fixing claw 430 ensure the stability of the guide cylinder 410 along its axial direction, allowing the guide cylinder 410 to better guide the sampling cylinder 100.
[0046] In some embodiments, see Figure 1 , Figure 3 and Figure 5 Both the first fixing claw 420 and the second fixing claw 430 are hinged to the guide cylinder 410. The first fixing claw 420 and the second fixing claw 430 can be stored at their ends against the guide cylinder 410, reducing space occupation and improving portability.
[0047] In some embodiments, see Figure 1 , Figure 3 and Figure 5There are four first fixing claws 420 and four second fixing claws 430, and their projections on the horizontal plane are staggered. In their projections on the horizontal plane, the first fixing claws 420 and second fixing claws 430 are evenly spaced. This staggered arrangement of the first fixing claws 420 and second fixing claws 430 minimizes interference during their deployment, facilitates better gripping of the first protrusion 421 and second protrusion 431, and allows the first fixing claws 420 and second fixing claws 430 to provide stable support for the guide cylinder 410.
