Description

Technical Field

[0001] This utility model relates to the technical field of soil testing equipment, specifically to a soil sampling device for soil testing. Background Technology

[0002] Soil environmental monitoring determines environmental quality and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Before soil testing, it is necessary to take samples at the testing site. The sampling depth for the surface layer is 0-20 cm, the sampling depth for the middle layer is 20-60 cm, and the sampling depth for the deep layer is 60-100 cm. Existing soil sampling devices have complex structures and are prone to bringing upper soil to the lower layer during sampling, thus affecting the accuracy of middle and lower soil sampling. Utility Model Content

[0004] This utility model includes a soil sampling rod and a sleeve. The top end of the soil sampling rod is provided with a main handle, and the bottom end of the soil sampling rod is provided with a soil sampling inner cylinder. A set of soil sampling ports are arranged in a ring on the soil sampling inner cylinder, and a soil sampling plate is provided on one side of the soil sampling port. A soil breaking cone is provided at the bottom end of the soil sampling inner cylinder. A foot pedal is provided on the sleeve, and a set of soil sampling plate avoidance grooves is provided at the bottom end of the sleeve. The sleeve can be moved up and down and fitted onto the soil sampling rod.

[0006] The bottom of the soil extraction inner cylinder is open, and the soil breaking cone is threaded onto the bottom opening of the soil extraction inner cylinder.

[0007] The top diameter of the soil-breaking cone is the same as the outer diameter of the sleeve. Both sides of the bottom end of the soil-taking plate are chamfered. The working diameter of the soil-taking plate is larger than the diameter of the soil-breaking cone.

[0008] The opening direction of the soil sampling port is offset from the axis of the inner cylinder of the soil sampling port, and the soil sampling plate is set parallel to the opening direction of the soil sampling port.

[0009] The inner cylinder of the soil sampling chamber is equipped with a material sampling plate. A set of guide plates corresponding to the soil sampling port are arranged in a ring on the material sampling plate. A push-pull rod with one end penetrating the soil sampling rod is provided on the top of the material sampling plate.

[0010] A push handle is provided at one end of the push-pull rod, and a return spring is provided between the push handle and the main handle.

[0011] The advantages of this utility model are: after the inner soil sampling cylinder is inserted to the sampling depth, the sleeve is lifted upward to expose the soil sampling opening. The soil sampling rod is rotated, and the soil sampling plate pushes the soil sample located around the perimeter from the soil sampling opening into the inner soil sampling cylinder. After the sleeve is lowered, the soil sampling opening is closed. During the soil sampling process, it effectively prevents the upper soil layer from entering the inner soil sampling cylinder, thereby improving the accuracy of sampling. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] As shown in the attached figure, this utility model includes a soil sampling rod 1 and a sleeve 2. The top end of the soil sampling rod 1 is provided with a main handle 3, and the bottom end of the soil sampling rod 1 is provided with a soil sampling inner cylinder 4. A set of soil sampling ports 5 are arranged in a ring on the soil sampling inner cylinder 4, and a soil sampling plate 6 is provided on one side of the soil sampling port 5. A soil breaking cone 7 is provided at the bottom end of the soil sampling inner cylinder 4. A foot pedal 10 is provided on the sleeve 2, and a set of soil sampling plate avoidance grooves 11 are provided at the bottom end of the sleeve 2. The sleeve 2 can be moved up and down and fitted onto the soil sampling rod 1.

[0022] When using the device, insert the soil-breaking cone 7 into the sampling position. By stepping on the pedal 10, the sleeve 2 presses the soil-breaking cone 7 and the soil-taking inner cylinder 4 into the soil. Set the scale marks on the sleeve 2. According to the sampling depth, insert the soil-taking inner cylinder 4 into the designated position. Then lift the sleeve 2 upwards. At this time, the soil-taking opening 5 is exposed. Rotate the soil-taking rod 1 one turn. The soil-taking plate 6 pushes the soil located around it into the soil-taking inner cylinder 4. Then lower the sleeve 2. At this time, the soil-taking opening 5 is closed. Lift the soil-taking rod 1 upwards to pull the soil-taking inner cylinder 4 out of the ground. After removing the soil-breaking cone 7, take out the soil in the soil-taking inner cylinder 4.

[0023] Furthermore, an extension tube 12 is provided at one end of the top of the sleeve 2, and a secondary handle 13 is provided on the extension tube 12. A tensioning spring 15 is provided between the secondary handle 13 and the main handle 3.

[0024] The extension cylinder 12 and the sleeve 2 are welded together. Under the default condition, the tension spring 15 holds the sleeve 2 downward and tightens it on the soil breaking cone 7, so that the soil extraction port 5 is in a closed state. When the auxiliary handle 13 and the main handle 3 are squeezed by external force, the sleeve 2 rises a certain distance and the soil extraction port 5 is exposed. After being released, the sleeve 2 returns to its original position under the action of the tension spring 15, and the soil extraction port 5 is closed.

[0025] Preferably, the bottom of the soil-receiving inner cylinder 4 is open, and the soil-breaking cone 7 is threadedly connected to the bottom opening of the soil-receiving inner cylinder 4. The top of the soil-breaking cone 7 is provided with an internal thread, and one end of the bottom of the soil-receiving inner cylinder 4 is provided with an external thread. The two are threadedly connected, allowing for quick disassembly and installation.

[0026] Preferably, the top diameter of the soil-breaking cone 7 is the same as the outer diameter of the sleeve 2. During soil extraction, the top of the soil-breaking cone 7 and the sleeve 2 are on the same plane, facilitating quick insertion and removal. The bottom of the soil-extraction plate 6 has chamfers on both sides, giving it a blade-like structure and reducing resistance when inserted into the ground. The working diameter of the soil-extraction plate 6 is larger than the diameter of the soil-breaking cone 7. After being inserted into the ground, the soil-extraction plate 6, when rotating, can scrape soil within its working radius into the inner soil-extraction cylinder 4.

[0027] The top of the soil sampling plate 6 is inclined, and the entire soil sampling device is pulled outward, which can reduce the resistance of the soil sampling plate 6.

[0028] Preferably, the opening direction of the soil sampling port 5 is offset from the axial direction of the soil sampling inner cylinder 4, and the soil sampling plate 6 is arranged parallel to the opening direction of the soil sampling port 5.

[0029] The soil sampling plate 6 and the soil sampling inner cylinder 4 form an angle. When rotating, the soil within the working radius can quickly enter the soil sampling inner cylinder 4. The direction of rotation of the soil sampling inner cylinder 4 should be towards the soil sampling port 5.

[0030] Furthermore, the inner cylinder 4 is equipped with a material taking plate 17, and a set of guide plates 18 corresponding to the soil taking port 5 are arranged in a ring on the material taking plate 17. The top of the material taking plate 17 is equipped with a push-pull rod 19 that passes through the soil taking rod 1 at one end.

[0031] The material-removing plate 17 is used to remove the soil from the soil-removing inner cylinder 4. By pressing one end of the push-pull rod 19, the material-removing plate 17 moves downward, thereby pushing out the soil from the soil-removing inner cylinder 4.

[0032] A push-pull rod 19 has a pressing handle 20 at one end, and a return spring 21 is provided between the pressing handle 20 and the main handle 3.
