Description

Technical Field

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

[0002] Soil is the basic carrier of agricultural production and a core element of the ecological environment. In order to understand the soil fertility status, so as to accurately fertilize according to the needs of crops and avoid fertilizer waste and environmental pollution caused by blind fertilization, and at the same time, to take corresponding measures to improve soil structure based on the tested physical properties of the soil, it is necessary to sample and test the soil.

[0003] Traditional sampling devices mostly involve inserting an outer cylinder into the soil to facilitate soil sampling. However, existing sampling devices are prone to loosening of the outer cylinder due to the reaction force of the soil during sampling, which fails to provide effective support for the sampling cylinder to penetrate deeper into the soil, thus affecting the sampling efficiency of the device. At the same time, since the device does not screen out the surface soil, soil from different depths is easily mixed, affecting the accuracy of the test results. After searching, it was found that the technical solution provided by the utility model with application number CN202320568856.3 also has the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a soil sampling and testing device that facilitates the opening of the diversion plate after the outer cylinder is inserted into the soil, thereby increasing the support area of ​​the diversion plate on the soil, increasing the support force of the outer cylinder for the sampling cylinder to sample deeper into the soil, and improving the practicality and sampling efficiency of the device.

[0007] According to the aforementioned soil sampling and testing device, the number of diversion plates is four and arranged in a circular array. The outer surface of the diversion plates is provided with helical blades, which facilitates increasing the pressure on the soil when they are closed. The rotation of the helical blades provides downward drilling force, reducing the consumption of manpower.

[0008] According to the aforementioned soil sampling and testing device, a limiting ring is fixedly connected to the outer surface of the adjusting rod, and the outer surface of the limiting ring is slidably connected to the adjusting seat, which facilitates the restriction of the relative position between the limiting ring and the adjusting rod, and facilitates the adjustment rod to rotate while driving the adjusting seat to move up and down.

[0009] According to the aforementioned soil sampling and testing device, a limiting block is fixedly connected to the upper outer surface of the sampling tube, and a limiting groove is provided on the inner sidewall of the inner cavity.

[0010] According to the aforementioned soil sampling and testing device, the inner surface of the limiting groove is slidably connected to the limiting block, and the outer surface of the sampling rod is threadedly connected to the adjusting rod, which facilitates the rotation of the sampling rod to drive the sampling cylinder to move, guides the movement of the sampling cylinder, and prevents the sampling cylinder from rotating.

[0011] According to the aforementioned soil sampling and testing device, the outer surface of the connecting rod slides with the first connecting seat, and the outer surface of the connecting rod slides with the second connecting seat.

[0012] According to the aforementioned soil sampling and testing device, the two sides of the connecting plate slide against the outer cylinder, and the outer surface of the connecting shaft is rotatably connected to the outer cylinder.

[0013] According to the aforementioned soil sampling and testing device, the outer surface of the adjusting rod slides against the outer cylinder.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. Adjusting the connecting rod by rotating the adjusting rod facilitates the opening of the diversion plate after the outer cylinder is inserted into the soil, thereby increasing the support area of ​​the diversion plate on the soil, increasing the support force of the outer cylinder for the sampling cylinder to sample deeper into the soil, and improving the practicality and sampling efficiency of the device.

[0016] 2. The diversion plate allows the soil to separate outwards when the outer cylinder is inserted, facilitating the insertion of the outer cylinder. At the same time, the diversion plate can also pry the soil outwards after it opens, enabling the device to accurately sample the soil at the required depth and improve the accuracy of the test results.

[0027] A second fixed shaft 10 is fixedly connected to the inner surface of the end of the connecting rod 9 away from the first fixed shaft 8. A second connecting seat 11 is rotatably connected to the outer surface of the second fixed shaft 10. The outer surface of the connecting rod 9 slides against the second connecting seat 11. A flow divider 12 is fixedly connected to the side surface of the second connecting seat 11. There are four flow dividers 12 arranged in a circular array. The outer surface of the flow dividers 12 is provided with helical blades 20. When the flow dividers 12 are closed, the helical blades 20 can connect with each other, which facilitates the downward drilling force provided to the device when it rotates.

Once the desired position is reached, the adjusting rod 5 is rotated by the first turntable 18. Under the threaded connection between the adjusting rod 5 and the threaded cylinder 4, the adjusting seat 6 moves downward, causing the lower end of the connecting rod 9 to open outward. This causes the diverter plate 12 to open outward with the connecting shaft 14 as the axis, increasing the support area of ​​the diverter plate 12 on the soil while digging the soil outward. The sampling rod 17 is rotated by the second turntable 19. The rotation of the sampling rod 17 causes the sampling cylinder 16 to move downward, thus inserting it into the soil for sampling. After sampling, the device can be removed by reversing the above operation.
