[0022] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application, obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application. DETAILED DESCRIPTION

[0024] Please refer to Figures 1-4 , the present application is a kind of quick soil depth auxiliary soil taking device, including the slide 1 that can move in vertical direction, slide 1 can rotate in horizontal direction;

[0025] Further comprising support 10, support 10 is provided with electric telescopic rod 11 that can drive slide 1 to slide in vertical direction, support 10 is provided with servo motor 12 that can drive electric telescopic rod 11 to rotate in horizontal direction;

[0026] Specifically, when using the device, place it on the soil surface, then drive the telescopic end of the electric telescopic rod 11 to extend downwards, causing the slide 1 to move downwards and closer to the soil surface. Adjust the length of the telescopic end of the electric telescopic rod 11 according to the required sampling depth, and then start the servo motor 12 to drive the slide 1 to rotate, so that the slide 1 rotates in the soil to collect samples.

[0027] Specifically, the bottom surface of the support 10 is evenly distributed in a circular array with several vertically arranged stabilizing legs 13;

[0028] Specifically, before use, place the stabilizing leg 13 on the soil surface to support the device on the soil surface.

[0029] Furthermore, several vertically arranged slide plates 2 are evenly slidably arranged on the surface of the slide 1. The sides of the slide plates 2 are provided with scale lines. The scale markings are formed on the side surface of the slide plates 2 using laser etching technology and are equipped with a wear-resistant and corrosion-resistant coating to ensure the scale identification and equipment durability under complex field working conditions.

[0030] The scale lines come in two sizes: 50cm and 100cm. The dual scales are designed to meet the different soil sampling needs of different ecosystems. The 50cm increment scale line is specifically used for soil sampling depth calibration in forest ecosystems, while the 100cm increment scale line is suitable for full-depth sampling needs in grassland or farmland ecosystems. When the slide plate 2 penetrates the soil medium vertically, the operator can directly read the insertion depth of the slide plate by observing the exposed scale markings. This enables rapid identification and accurate positioning of soil sampling depths in different ecosystems, effectively improving the standardization of field sampling data.

[0031] The surface of the slide 1 is evenly distributed in a circular array with several guide grooves 6. I-shaped guide blocks 7 are slidably arranged on the inner wall of the guide grooves 6. A guide shaft 8 is fixed between the bottom surface of the I-shaped guide block 7 and the surface of the slide 2.

[0032] Specifically, the sliding I-shaped guide block 7 along the guide groove 6 drives the guide shaft 8 to move, which in turn drives the slide plate 2 to move, thereby changing the distance between the slide plate 2 and the center position of the slide frame 1. When the slide frame 1 rotates, it will drive the slide plate 2 to rotate. Therefore, by adjusting the position of the slide plate 2, the diameter of the slide plate 2 in the soil can be changed.

[0033] Furthermore, a guide ring 9 is fixed to the bottom surface of the slide 1 by fastening bolts. The guide ring 9 is set on the rotation path of the slide 2, and the guide shaft 8 is fitted into the inner wall of the guide ring 9.

[0034] Specifically, the guide ring 9 is provided with multiple groups of different specifications, including a diameter of 3 cm, a diameter of 6 cm, and a diameter of 20 cm. The soil sample is collected by the guide ring with a diameter of 3 cm, the root sample is collected by the guide ring with a diameter of 6 cm, and the soil animal sample is collected by the guide ring with a diameter of 20 cm. Different guide rings 9 are installed according to the specific sample to be collected.

[0035] When the guide ring 9 is installed, first, all the sliding plates 2 are inserted into the guide channel on the inner wall of the guide ring 9, and then the guide ring 9 is slid upward, and the guide ring 9 is fixed coaxially on the bottom surface of the sliding frame 1 by the fastening bolt, so that the distance from all the sliding plates 2 to the center position of the sliding frame 1 is the same, and the installation and disassembly are convenient.

[0036] Further, the opposite sides and the opposite sides of each sliding plate 2 are symmetrically provided with two sliding grooves 3, and the inner wall of the sliding groove 3 is horizontally slidably provided with a push plate 4;

[0037] The inner wall of the sliding groove 3 is fixed with a spring 5 which can push the push plate 4 to slide outward, and the two push plates 4 are opposite in the direction of the elastic force of the corresponding spring 5;

[0038] Specifically, first, the device is placed on the soil surface, the sliding frame 1 is driven downward by the electric telescopic rod 11, and then the sliding plate 2 is inserted into the soil inside, and the bottom of the sliding plate 2 and the bottom of the push plate 4 are chamfered, which reduces the resistance of the sliding plate 2 inserted into the soil inside;

[0039] The push plate 4 will slide outward due to the pushing force of the spring 5, so that the push plate 4 will press the soil, and then the soil located in the inner circle of each sliding plate 2 will be compressed inward, and the soil located in the outer circle of each sliding plate 2 will be pushed outward;

[0040] Then, the servo motor 12 is started to drive the sliding frame 1 to rotate, and then the sliding plate 2 is rotated, so that the soil in the corresponding circle is separated as a whole, and the push plate 4 pushes the soil, so that the soil in the inner and outer circles is separated and layered, and the soil in the inner circle is more compact, which is conducive to the overall grabbing of the soil sample.

[0041] Further, the movable displacement of the push plate 4 in the sliding groove 3 pushed by the spring 5 is less than the horizontal length of the sliding groove 3, which prevents the push plate 4 from moving excessively and sliding out of the sliding groove 3, causing the push plate 4 to fall off and affecting the subsequent sampling of the soil.

[0042] Further, the sliding plate 2 is rotatably provided with a drag plate 14 which can rotate between the horizontal direction and the vertical upward direction;

[0043] Specifically, when the carriage 1 is moved downward, the drag plate 14 is folded in a vertical upward state, when the sampling is finished and the soil is grabbed upward, the drag plate 14 is subjected to downward resistance, and then the drag plate 14 is folded downward, the maximum folding angle is 90°, that is, the drag plate 14 is folded to a horizontal state, which can provide a certain supporting force for the bottom of the sample, and is more conducive to the upward grabbing of the sample.
