This device has the advantage of enabling precise sampling of soil quantity, solving the problem that existing soil samplers are tools specifically designed for collecting soil samples. The importance of quantitative soil sampling lies in ensuring the representativeness and comparability of the samples, which is crucial for soil quality assessment and environmental monitoring. Quantitative sampling can reduce sampling errors and improve the accuracy and reliability of data. Currently, existing pattern samplers require manual separation after sampling, which is not only wasteful of manpower but also lacks precision, easily leading to reduced sampling efficiency and accuracy. Furthermore, existing soil samplers for soil environmental testing lack components for precise soil quantity sampling.

[0004] This utility model is implemented as follows: a soil environmental testing sampling device includes a soil sampling shell and a bulldozing handle. The bulldozing handle is movably connected to the inner cavity of the soil sampling shell. The top of the bulldozing handle penetrates the soil sampling shell and extends to the outer side of the inner cavity of the soil sampling shell. A device groove is opened inside the bulldozing handle. A control frame is movably connected to the inner cavity of the device groove. Both the left and right sides of the control frame penetrate the device groove and extend to the outer side of the inner cavity of the device groove. An adjustment device is provided in the inner cavity of the device groove.

[0005] In a preferred embodiment of this invention, the adjusting device includes two adjusting blocks. The two adjusting blocks have opposite sides that penetrate the device groove and extend to the outer side of the inner cavity of the device groove. Two limiting holes are formed on the surface of each adjusting block. Two limiting rods that cooperate with the limiting holes are fixedly connected to the inner cavity of the device groove. The surface of each limiting rod is movably connected to the inner cavity of the limiting hole. A spring is sleeved on the surface of each limiting rod, and both sides of the spring are fixedly connected to the surface of the adjusting block. By providing the adjusting device, when the position of the bulldozer handle needs to be adjusted according to the amount of soil sample taken, the adjusting device has an adjusting function on the position of the bulldozer handle.

[0006] As a preferred embodiment of this utility model, a movable column frame is fixedly connected to the top of the adjusting block, and two extrusion rotating frames that cooperate with the movable column frame are movably connected to the rear side of the inner cavity of the device groove via a rotating shaft. The surface of the movable column frame is movably connected to the inner cavity of the extrusion rotating frame. By setting the movable column frame and the extrusion rotating frame, when the extrusion rotating frame rotates, it can generate extrusion force on the movable column frame, and the movable column frame subjected to extrusion force can drive the movable column frame to move.

[0007] As a preferred embodiment of this utility model, a square extrusion frame is fixedly connected to the surface of the control frame for use with the extrusion rotating frame. The surface of the square extrusion frame is movably connected to the inner cavity of the extrusion rotating frame.

The cooperation of the sliding block and the sliding hole has a limiting effect on the movement position of the bulldozer handle.

[0010] As a preferred embodiment of this utility model, a scale strip is fixedly connected to the front side of the soil sampling shell. By setting the scale strip, the bulldozer handle can be moved to a precise position.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of existing soil samplers being tools specifically designed for collecting soil samples. The importance of quantitative soil sampling lies in ensuring the representativeness and comparability of the samples, which is crucial for soil quality assessment and environmental monitoring.

However, existing soil samplers used for soil environmental testing lack components for precise soil volume sampling.

[0013] 2. This utility model, by setting an adjustment device, will cause two adjustment blocks to move closer to each other when the moving column frame moves. When the adjustment blocks move, they will cause the limiting hole to move along the surface of the limiting rod. At the same time, the squeezing force generated by the movement of the adjustment blocks will cause the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will cause the adjustment block to be locked into the inner cavity of the adjustment groove. The cooperation between the adjustment block and the adjustment groove has a limiting effect on the position of the bulldozer handle, and the adjustment device has an adjusting effect on the position of the bulldozer handle.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, a soil environmental testing sampling device provided by this utility model includes a soil sampling shell 1 and a bulldozing handle 2. The bulldozing handle 2 is movably connected to the inner cavity of the soil sampling shell 1. The top of the bulldozing handle 2 penetrates the soil sampling shell 1 and extends to the outside of the inner cavity of the soil sampling shell 1. A device groove 3 is provided inside the bulldozing handle 2. A control frame 4 is movably connected to the inner cavity of the device groove 3. The left and right sides of the control frame 4 penetrate the device groove 3 and extend to the outside of the inner cavity of the device groove 3. An adjustment device 5 is provided in the inner cavity of the device groove 3.

[0022] refer to Figure 4 The adjusting device 5 includes two adjusting blocks 501. The two adjusting blocks 501 have opposite sides that pass through the device groove 3 and extend to the outside of the inner cavity of the device groove 3. Two limiting holes 502 are opened on the surface of the adjusting blocks 501. Two limiting rods 503 that cooperate with the limiting holes 502 are fixedly connected to the inner cavity of the device groove 3. The surface of the limiting rods 503 is movably connected to the inner cavity of the limiting holes 502. A spring 504 is sleeved on the surface of the limiting rods 503. The left and right sides of the spring 504 are fixedly connected to the surface of the adjusting blocks 501.

[0023] The above scheme is adopted: by setting the adjustment device 5, when the position of the bulldozer handle 2 needs to be adjusted according to the amount of soil sampling, the adjustment device 5 has the function of adjusting the position of the bulldozer handle 2.

[0024] refer to Figure 4 The top of the adjusting block 501 is fixedly connected to a movable column frame 6. The rear side of the inner cavity of the device groove 3 is movably connected by a rotating shaft to two extrusion rotating frames 7 that cooperate with the movable column frame 6. The surface of the movable column frame 6 is movably connected to the inner cavity of the extrusion rotating frame 7.

[0025] The above scheme is adopted: by setting a movable column frame 6 and a pressing rotating frame 7, when the pressing rotating frame 7 rotates, it can generate a pressing force on the movable column frame 6, and the movable column frame 6 under the pressing force can move.

[0026] refer to Figure 4 A square extrusion frame 8, which is used in conjunction with the extrusion rotating frame 7, is fixedly connected to the surface of the control frame 4. The surface of the square extrusion frame 8 is movably connected to the inner cavity of the extrusion rotating frame 7.

[0027] The above solution is adopted: by setting a square extrusion frame 8, when the control frame 4 moves, it will drive the square extrusion frame 8 to move. When the square extrusion frame 8 moves, it can generate extrusion force on the extrusion rotating frame 7 and drive the extrusion rotating frame 7 to rotate through the rotating shaft.

[0028] refer to Figure 3 The soil sampling shell 1 has adjustment grooves 9 on both the left and right sides of its inner cavity, which are used in conjunction with adjustment blocks 501. The surface of adjustment block 501 is in contact with the inner cavity of adjustment groove 9. There are several adjustment grooves 9, which are evenly distributed on the left and right sides of the inner cavity of soil sampling shell 1.

[0029] The above scheme is adopted: by setting the adjustment groove 9, when the bulldozer handle 2 moves to the appropriate position in the inner cavity of the soil sampling shell 1, the control frame 4 is released, and the restoring force generated by the spring 504 returning to its shape will drive the adjustment block 501 to be inserted into the inner cavity of the adjustment groove 9. The cooperation between the adjustment block 501 and the adjustment groove 9 has a limiting effect on the movement position of the bulldozer handle 2.

[0030] refer to Figure 2 The front and rear sides of the bulldozer handle 2 are fixedly connected with sliding blocks 10. The front and rear sides of the soil sampling shell 1 are provided with sliding holes 11 that cooperate with the sliding blocks 10. The inner cavity of the sliding hole 11 is movably connected to the surface of the sliding block 10.

[0031] The above solution is adopted: by setting the sliding block 10 and the sliding hole 11, when the bulldozer handle 2 moves, it will drive the sliding block 10 to move up or down along the inner cavity of the sliding hole 11. The cooperation of the sliding block 10 and the sliding hole 11 has a limiting effect on the movement position of the bulldozer handle 2.

[0032] refer to Figure 2 A scale strip 12 is fixedly connected to the front side of the soil sampling shell 1.

[0033] The above solution is adopted: by setting the scale bar 12, the bulldozer handle 2 can be moved to a precise position.

[0034] The working principle of this utility model:

[0035] When using the soil sampler for soil environmental testing, which requires precise soil sampling, the operator first pulls the control frame 4 upwards. As the control frame 4 moves, it causes the square extrusion frame 8 to move along the inner cavity of the extrusion rotating frame 7. The extrusion rotating frame 7, subjected to extrusion pressure, rotates along the surface of the moving column frame 6 via a rotating shaft. The extrusion pressure exerted by the extrusion rotating frame 7 on the moving column frame 6 causes the two moving column frames 6 to move closer together. When the moving column frames 6 move, they cause the two adjusting blocks 501 to move closer together. When the adjusting blocks 501 move, they cause the limiting hole 502 to move along the surface of the limiting rod 503. Simultaneously, the extrusion pressure generated by the movement of the adjusting blocks 501 causes the spring 504 to undergo elastic deformation. When fully moved into the inner cavity of the device slot 3, pull the bulldozer handle 2 to the top or bottom. At the same time, the bulldozer handle 2 will drive the sliding block 10 to move along the inner cavity of the sliding hole 11. When the bottom of the bulldozer handle 2 moves to the appropriate scale line, release the control frame 4. The restoring force generated by the spring 504 returning to its shape will drive the adjusting block 501 to be locked into the inner cavity of the adjusting slot 9. The cooperation between the adjusting block 501 and the adjusting slot 9 has a limiting effect on the position of the bulldozer handle 2. At this time, the bulldozer handle 2 makes the sampling space of the soil sampling shell 1 at a precise value. Then, the soil sampling shell 1 is inserted into the soil to be sampled. After sampling is completed, the quantitative soil sample can be pushed out by the bulldozer handle 2. At this time, the soil sampler used for soil environmental testing completes the precise sampling of soil volume.

[0036] In summary, this soil environmental testing sampling device, through the coordinated use of the adjusting device 5, adjusting block 501, limiting hole 502, limiting rod 503, and spring 504, solves the problem that existing soil samplers are tools specifically designed for collecting soil samples. The importance of quantitative soil sampling lies in ensuring the representativeness and comparability of the samples, which is crucial for soil quality assessment and environmental monitoring. Quantitative sampling can reduce sampling errors and improve the accuracy and reliability of data. Typically, existing pattern samplers require manual separation after sampling, which is not only wasteful of manpower but also lacks precision, easily leading to reduced sampling efficiency and accuracy. However, existing soil samplers used for soil environmental testing lack components for precise soil volume sampling.
