DETAILED DESCRIPTION

[0022] The utility model will be described in further detail with reference to the drawings.

[0023] The soil layer sampler of the forest ecosystem different vegetation under the specific embodiment of the utility model, please refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4 , comprising mounting seat 1, the outer side of mounting seat 1 is provided with support assembly 2, the inside of mounting seat 1 is provided with sampling assembly 3;

[0024] Support assembly 2 includes stand 201, the inside of stand 201 is movably connected with slider 202, the outer side of slider 202 is fixedly connected with limit block 203, one side of slider 202 is fixedly connected with connecting block 204, the outer side of stand 201 is fixedly connected with positioning plate 205, the bottom of stand 201 is fixedly connected with plug-in rod 206.

[0025] The number of the stand column 201 is two and symmetrically distributed on the left and right sides of the mounting seat 1, the limiting block 203 is fixedly connected on the front and back sides of the sliding block 202, and the inner wall of the stand column 201 is provided with limiting grooves on the front and back sides, which are matched with the moving track of the limiting block 203.

[0026] By designing two symmetrically distributed stand columns 201 and equipping the limiting block 203 to slide in the limiting groove in the inner wall of the stand column 201, the stability of the supporting assembly 2 and the accuracy of the sliding of the sliding block 202 are ensured. This design not only enhances the structural strength of the entire sampler, but also makes the sliding block 202 not easy to deviate or shake during movement, thereby improving the stability and reliability of the sampling operation.

[0027] The side of the connecting block 204 away from the sliding block 202 is fixedly connected with the mounting seat 1, and the side of the stand column 201 close to the mounting seat 1 is provided with an avoiding hole matched with the moving track of the connecting block 204.

[0028] The connecting block 204 is connected with the stand column 201 through the avoiding hole. This design allows the connecting block 204 to smoothly pass through the avoiding hole when the sliding block 202 slides in the stand column 201, without being hindered. This not only ensures the smooth movement of the sliding block 202, but also makes the connection between the mounting seat 1 and the supporting assembly 2 more stable, improving the overall stability of the sampler.

[0029] The plug rod 206 is designed in a conical shape, and the projection area of the positioning plate 205 in the vertical direction is greater than the projection area of the plug rod 206 in the vertical direction.

[0030] The conical design of the plug rod 206 facilitates its insertion into the soil, increasing the contact area between the sampler and the soil and improving the stability during sampling. At the same time, the projection area of the positioning plate 205 is greater than that of the plug rod 206, which can more effectively prevent the sampler from tilting or moving during sampling, thereby ensuring the accuracy and stability of the sampling.

[0031] The sampling assembly 3 includes an electric push rod 301, the inside of the mounting seat 1 is fixedly connected with a mounting cylinder 302, the inside of the mounting cylinder 302 is slidably connected with a transmission block 303, the top of the transmission block 303 is fixedly connected with a connecting rod 304, and the bottom of the transmission block 303 is fixedly connected with a sampling cylinder 305.

[0032] The electric push rod 301 drives the sampling cylinder 305 to sample the soil, achieving automation and precise control of the sampling process. This design not only improves the sampling efficiency, but also reduces the difficulty and labor intensity of manual operation.

[0033] The number of electric push rods 301 is two and they are fixedly connected at the top of the two columns 201, and the output shaft of the electric push rod 301 extends to the inside of the column 201 and is fixedly connected with the top of the sliding block 202.

[0034] The output shaft of the electric push rod 301 is fixedly connected with the top of the sliding block 202, which enables the electric push rod 301 to directly drive the sliding block 202 to slide in the column 201, and then drives the mounting seat 1 and the sampling assembly 3 to move up and down through the connecting block 204, which not only realizes the adjustment of the sampling depth, but also makes the sampling process more flexible and controllable.

[0035] The inside of the mounting seat 1 is provided with a circular through hole, and the mounting cylinder 302 is fixedly connected in the circular through hole, and the inner wall of the mounting cylinder 302 is provided with a transmission groove matched with the movement track of the transmission block 303, and the diameter of the transmission block 303 is greater than that of the sampling cylinder 305, and the top of the connecting rod 304 is fixedly connected with a disc-shaped handle, and the lower end of the sampling cylinder 305 is in a closed shape.

[0036] The transmission groove in the mounting cylinder 302 is matched with the movement track of the transmission block 303, which ensures the stability and accuracy of the transmission block 303 during sliding, and the diameter of the transmission block 303 is greater than that of the sampling cylinder 305, which can prevent the sampling cylinder 305 from falling accidentally during sampling, in addition, the disc-shaped handle at the top of the connecting rod 304 facilitates the operator to hold and control the sampler, and the lower end of the sampling cylinder 305 is in a closed shape, which not only facilitates drilling into the soil, but also helps to reduce the loss of soil samples during sampling, ensuring the integrity of the sampling.

[0037] The working principle is as follows: first, place the entire sampling device in the area of the forest where sampling is needed, then insert the insertion rod 206 downward until the insertion rod 206 is fully inserted into the soil, the bottom of the positioning plate 205 is in contact with the soil surface, the position of the entire sampling device can be fixed, then the output end of the electric push rod 301 is extended, the sliding block 202 is driven downward by the electric push rod 301, under the limitation of the limiting block 203 and the limiting groove, the sliding block 202 moves up and down linearly, under the transmission of the connecting block 204, the mounting seat 1 drives the mounting cylinder 302 to move downward, the mounting cylinder 302 is inserted into the soil, the depth of the mounting cylinder 302 inserted into the soil can be adjusted by adjusting the extension distance of the output end of the electric push rod 301, finally, the handle at the top of the connecting rod 304 is pushed to push the sampling cylinder 305 into the soil for sampling, after sampling, the output end of the electric push rod 301 is retracted, the sampling cylinder 305 and the mounting cylinder 302 are pulled out of the soil, during the pulling-out process, the soil in the sampling cylinder 305 is left in the sampling cylinder 305 due to the friction, thus the entire soil sampling process is completed.
