Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, and relates to a sampling device for soil improvement. Background Art

[0002] Soil improvement is a technical measure aimed at improving the physical and chemical properties of soil, increasing soil fertility, and creating a good soil environment for plant growth. Before soil improvement, it is necessary to use a soil sampling device to sample the soil, and then detect the soil in order to improve the soil targeted.

[0003] The existing sampling device has a plurality of through holes opened on the sampling cylinder. After the sampling cylinder is drilled into the soil, the soil is pressed through the through holes and enters the sampling cylinder. However, soil enters the sampling cylinder before the sampling cylinder reaches the sampling depth, and when the sampling cylinder is removed from the soil after sampling, soil also enters the sampling cylinder. This will lead to inaccurate soil sampling, and then inaccurate subsequent soil detection. Therefore, there is an urgent need for a sampling device for soil improvement to solve the above problems. Summary of the Utility Model

[0004] In view of the above technical problems existing in the prior art, a sampling device for soil improvement is provided. It can effectively prevent soil from entering the sampling cylinder before the sampling cylinder reaches the sampling depth, and when the sampling cylinder reaches the sampling depth, the through holes are opened, and the soil enters the plurality of sampling cavities in the sampling cylinder under the action of pressure, which can ensure more accurate soil sampling; the device has a simple structure and is easy to manufacture and use.

A plurality of evenly distributed partition plates are longitudinally sleeved and fixed outside the rotating rod. The outer walls of the plurality of partition plates are in contact with the inner wall of the sampling cylinder, so that the inside of the sampling cylinder is divided into a plurality of longitudinally distributed sampling cavities.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Please refer to Figures 1-4 for further description of the embodiments of the present utility model;

[0021] A soil improvement sampling device includes an auger 1, a sampling cylinder 2, and a power assembly. The auger 1 is welded to the bottom of the sampling cylinder 2, and the power assembly is installed above the sampling cylinder 2;

[0022] On both sides of the sampling cylinder 2, a number of through holes 3 are longitudinally distributed, and a first motor 4 is fixed at the top of the sampling cylinder 2. A rotating rod 5 is rotatably connected inside the sampling cylinder 2. The upper end of the rotating rod 5 penetrates out of the sampling cylinder 2 and is fixedly connected to the output end of the first motor 4. A number of uniformly distributed partition plates 8 are longitudinally sleeved and fixed on the outside of the rotating rod 5. The outer walls of the number of partition plates 8 are all in contact with the inner wall of the sampling cylinder 2, so that the inside of the sampling cylinder 2 is divided into a number of longitudinally distributed sampling chambers. The through holes 3 communicate with the adjacent sampling chambers. On both sides of the inside of each sampling chamber, a sealing plate 7 for blocking the through holes 3 is provided. A connecting rod 6 is welded between the sealing plate 7 and the rotating rod 5.

[0023] In this solution, in the initial state, the sealing plate 7 blocks the through hole 3 adjacent to it, which can prevent soil from entering the through hole 3 before the sampling cylinder 2 reaches the soil sampling depth, ensuring more accurate later soil inspection.

[0024] When it is necessary to sample the soil to be detected, the power assembly is used to drive the auger 1 and the sampling cylinder 2 into the soil to be detected. When the sampling cylinder 2 is about to enter the specified depth of the soil, the first motor 4 is externally powered. The first motor 4 will drive the rotating rod 5 to rotate, and the rotating rod 5 will drive the connecting rod 6, the sealing plate 7 and the partition plate 8 to rotate. After the first motor 4 is started for two seconds, it is turned off. At this time, the sealing plate 7 is staggered from the through hole 3. As the auger 1 and the sampling cylinder 2 continue to rotate downward, the soil at different depths will enter the multiple sampling chambers through the multiple longitudinal through holes 3 respectively, so as to realize sampling of the soil at different depths. After sampling is completed, the first motor 4 is restarted to drive the rotating rod 5 to rotate, prompting the sealing plate 7 to close the through hole 3. The first motor 4 works for two seconds and then is turned off. At this time, the sealing plate 7 completely closes the through hole 3, so as to prevent soil from continuing to enter its interior during the upward movement of the sampling cylinder 2, which can enhance the accuracy of later soil detection. Finally, the power assembly is used to drive the auger 1 and the sampling cylinder 2 to move upward, and the soil sampling work is completed.

[0025] Compared with the prior art, by using the first motor 4, the rotating rod 5, the connecting rod 6 and the sealing plate 7, the through hole 3 can be automatically opened or closed, which can effectively prevent no soil from entering the sampling cylinder 2 when the sampling cylinder 2 does not reach the sampling depth, and when the sampling cylinder 2 reaches the sampling depth, the through hole 3 is opened, and the soil enters the multiple sampling chambers in the sampling cylinder 2 under the action of pressure, which can ensure more accurate soil sampling; the device has a simple structure and is easy to manufacture and use.

[0026] A waterproof cover 9 is fixed outside the first motor 4.

[0027] In this solution, the waterproof cover 9 plays a role in waterproofing the first motor 4 and preventing soil from adhering to the first motor 4, and is used to protect the first motor 4.

[0028] The power assembly includes a second motor 11 and an electric cylinder 12. The output end of the electric cylinder 12 is fixed to the center of the top of the waterproof cover 9, and the output end of the second motor 11 is fixed to the top of the electric cylinder 12.

[0029] In this solution, when the power assembly is in use, the second motor 11 and the electric cylinder 12 are connected to an external power source. The second motor 11 will drive the electric cylinder 12 and the components below it to rotate. When the electric cylinder 12 works, it will drive the components below it to move down or up, so as to realize the auger 1 and the sampling cylinder 2 drilling into the soil or being removed from the soil.

[0030] A protective cover 10 is sleeved outside the power assembly.

[0031] In this solution, the protective cover 10 is used to protect the power assembly from being directly impacted by external objects.

[0032] A handle 13 is fixed to the top of the protective cover 10.

[0033] In this solution, when the user uses the device, they can hold the handle 13 so that the auger 1 and the sampling cylinder 2 can be stably and accurately moved to the designated place.

[0034] The sampling cylinder 2 includes a cylinder body 21 and a sealing cover 22. The auger 1 is welded to the bottom of the cylinder body 21. The sealing cover 22 is detachably connected to the top of the cylinder body 21 in a sealed manner. The upper end of the rotating rod 5 penetrates through the sealing cover 22. The first motor 4 and the waterproof cover 9 are both fixed to the top of the sealing cover 22;

[0035] In this solution, the sealing cover 22 and the cylinder body 21 can adopt detachable connection methods such as bolt connection and clamping. Since the sealing cover 22 and the cylinder body 21 are detachable, after the device is used, the user can remove the sealing cover 22 from the top of the cylinder body 21, and then remove the rotating rod 5 from the cylinder body 21, which is convenient for the user to clean the soil in the cylinder body 21 for later soil sampling.
