Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and in particular to a sampling device for soil testing. Background Technology

[0002] Soil testing refers to determining the soil environmental quality or pollution level by measuring representative values ​​of factors affecting soil environmental quality, and predicting its subsequent trends. Soil testing generally includes technical aspects such as sampling, sample preparation, analytical methods, result characterization, data statistics, and quality evaluation. Therefore, when testing the soil environment, it is necessary to first sample the soil for comparative analysis.

[0003] Currently, the following methods are used when sampling and testing soil:

[0004] 1. Digging is done using a shovel, but shovels are inconvenient to carry;

[0005] 2. When using a sampling ring to sample the soil, it is necessary to press the soil in and bring out the soil that has entered the sampling ring. When pressing down, the sampling ring is very easy to tilt or fall over, which makes sampling inconvenient. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a soil testing sampling device that can improve sampling stability, is easy to carry, and is simple and convenient.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A soil sampling device includes a support frame, a cross arm fixedly mounted on the upper end of the support frame, handles fixedly mounted on both ends of the cross arm, a support arm fixedly mounted on the lower end of the support frame, and support components mounted on both ends of the support arm.

[0009] The support arm has a protruding support base in the middle, a sampling ring is fixedly installed on the support base, a support block is fixedly installed on the bracket, and a material pushing component is installed on the support block.

[0010] In this way, during use, the sampling device is carried to the sampling position. The support assembly and sampling ring form a triangular support. Then, stepping on the support arm moves the sampling ring downwards, allowing soil to enter the ring. The sampling device is then lifted upwards, and the soil inside the ring becomes the sample. The pushing assembly then pushes the sample out of the ring for collection, allowing for subsequent testing. The support assembly design allows for better vertical downward movement of the sampling ring when the foot is on the support arm, improving stability. Furthermore, the purely mechanical structure eliminates the need for additional batteries, making it easy to carry.

[0011] The support assembly includes a support frame integrally formed with the support arm. The support frame is L-shaped and has a sliding hole. A support rod is slidably fitted in the sliding hole. A base is fixed to the lower end of the support rod, and a limit plate is fixed to the upper end of the support rod. A compression spring is sleeved on the outside of the support rod and is located between the support frame and the base.

[0012] The support frame has stiffening plates fixed on both sides, and the support rod is located between the two stiffening plates.

[0013] The sampling ring has a protruding edge at its upper end, which is fixedly connected to the support by bolts.

[0014] The material pushing assembly includes a push block that slides with the sampling ring, a push rod fixedly installed at the upper end of the push block, a through hole that slides with the push rod in the support block, an upper limit block and a lower limit block fixed on the outer side of the push rod, and the two ends of the upper limit block and the lower limit block are respectively located on both sides of the support block.

[0015] A pedal is fixedly installed at the upper end of the push rod.

[0016] In summary, this soil testing sampling device has the advantages of improving sampling stability, being easy to carry, and being simple and convenient. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0021] like Figure 1-3As shown, a soil sampling device includes a support 1, a cross arm 2 fixedly installed at the upper end of the support, handles 3 fixedly installed at both ends of the cross arm, a support arm 4 fixedly installed at the lower end of the support, and support components installed at both ends of the support arm.

[0022] The support arm has a support base 5 protruding from the middle, a sampling ring 6 is fixedly installed on the support base, a support block 7 is fixedly installed on the support, and a material pushing component is installed on the support block.

[0023] In this way, during use, the sampling device is carried to the sampling position. The support assembly and sampling ring form a triangular support. Then, stepping on the support arm moves the sampling ring downwards, allowing soil to enter the ring. The sampling device is then lifted upwards, and the soil inside the ring becomes the sample. The pushing assembly then pushes the sample out of the ring for collection, allowing for subsequent testing. The support assembly design allows for better vertical downward movement of the sampling ring when the foot is on the support arm, improving stability. Furthermore, the purely mechanical structure eliminates the need for additional batteries, making it easy to carry.

[0024] In implementation, the support assembly includes a support frame 8 integrally formed with the support arm. The support frame is L-shaped and has a sliding hole. A support rod 9 is slidably fitted within the sliding hole. A base 10 is fixed to the lower end of the support rod, and a limit plate 11 is fixed to the upper end of the support rod. A compression spring 12 is sleeved on the outer side of the support rod, located between the support frame and the base. The compression spring provides downward pressure to the support rod and facilitates its return to its original position.

[0025] During implementation, stiffening plates 13 are fixed on both sides of the support frame, and the support rod is located between the two stiffening plates. This improves the stability of the installation.

[0026] In practice, the upper end of the sampling ring has a protruding flange 14, which is fixedly connected to the support by bolts 15. This facilitates the installation of the sampling ring.

[0027] In implementation, the pushing assembly includes a push block 16 that slides with the sampling ring. A push rod 17 is fixedly installed on the upper end of the push block. The support block has a through hole that slides with the push rod. An upper limit block 18 and a lower limit block 19 are fixed to the outer side of the push rod, with the ends of the upper and lower limit blocks located on both sides of the support block. During pushing, the push rod is stepped on, causing it to move the push block and push out the soil inside the sampling ring. The upper and lower limit blocks prevent the push rod from detaching from the support block, improving overall integrity.

[0028] In practice, a pedal 20 is fixedly installed on the upper end of the push rod for easy foot use.

[0029] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
