Description

Technical Field

[0001] This utility model relates to the field of Panax notoginseng seedling technology, and in particular to a non-destructive testing device for the root growth status of Panax notoginseng seedlings. Background Technology

[0002] Panax notoginseng is a traditional Chinese medicine used to stop bleeding and remove blood stasis. It can help wounds heal and relieve pain caused by falls and sprains. It is often used to treat external bleeding, skin bruises and swelling, or joint pain. Its special components can quickly stop bleeding and promote the dissipation of blood stasis, achieving the effect of "stopping bleeding without leaving residual blood stasis." Panax notoginseng is mainly produced in Wenshan, Yunnan Province, where the unique natural environment results in a higher content of effective components and exceptional quality. During the cultivation of Panax notoginseng seedlings, it is necessary to monitor the growth status of the root system.

[0003] Currently, transparent seedling boxes are often used in the seedling cultivation process of Panax notoginseng. Staff can monitor the root growth of the seedlings from the outside, but it is inconvenient to monitor the root system of the seedlings inside the soil of the seedling box.

[0004] Therefore, it is necessary to provide a non-destructive testing device for the root growth status of Panax notoginseng seedlings to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem of not being able to detect the root system of Panax notoginseng seedlings inside the soil of the seedling tray during the current Panax notoginseng seedling cultivation process, this utility model provides a non-destructive testing device for the root growth status of Panax notoginseng seedlings.

[0006] The non-destructive testing device for the root growth status of Panax notoginseng seedlings provided by this utility model includes: a base; a seedling box disposed on the base; pin grooves formed on both sides of the seedling box; a top plate located at the top of the seedling box; a non-destructive testing mechanism installed on the top plate, the non-destructive testing mechanism being used to test the root growth status of Panax notoginseng seedlings; a lifting mechanism installed on the base, the lifting mechanism being used to control the lifting and lowering of the non-destructive testing mechanism; and a positioning mechanism installed on the base, the positioning mechanism being used to position the seedling box.

[0007] Preferably, the non-destructive testing mechanism includes: a plurality of discharge electrodes fixedly installed at the bottom of the top plate; a plurality of measuring electrodes fixedly installed at the bottom of the top plate; and an impedance analyzer installed at the top of the top plate and electrically connected to the plurality of discharge electrodes and the plurality of measuring electrodes.

[0009] Preferably, the base has two limiting grooves, and two vertical plates are fixedly installed on the top inner wall of the base.

[0010] Preferably, the positioning mechanism includes: a second dual-axis motor fixedly installed on the inner wall of the top of the base; two screws fixedly installed at both ends of the output shaft of the second dual-axis motor and rotatably connected to the two vertical plates respectively; two sliding plates threaded onto the two screws and slidably connected to the inner walls on both sides of the two limiting grooves respectively; and two pin blocks fixedly installed on one side of the two sliding plates and adapted to the two pin grooves respectively.

[0011] Preferably, the same limiting rod is fixedly installed on the side of the two vertical plates that are close to each other, and both limiting rods are slidably connected to the two sliding plates.

[0013] Compared with related technologies, the non-destructive testing device for the root growth status of Panax notoginseng seedlings provided by this utility model has the following beneficial effects:

[0014] This invention provides a non-destructive testing device for the root growth status of Panax notoginseng seedlings. Panax notoginseng seedlings are raised in a seedling box made of transparent acrylic material, allowing staff to directly observe the root growth of the seedlings from the outside. A non-destructive testing mechanism provides comprehensive monitoring of the seedling root growth. A lifting mechanism moves the non-destructive testing mechanism up and down, while a positioning mechanism positions the seedling box at the top of the base. An impedance analyzer controls multiple discharge electrodes to inject current, and multiple measuring electrodes measure the voltage, thus obtaining the soil impedance without plants as a background value (impedance (Z) = resistance (R) + reactance (X), including amplitude and phase information). Multiple impedance measurements are then performed at different stages of Panax notoginseng seedling growth, and the impedance data is analyzed using an impedance analyzer to determine the root growth status. The detection mainly includes low-frequency, mid-high-frequency, and high-frequency measurements. Low-frequency (<1kHz): the current mainly passes through the soil solution, reflecting the soil... Soil moisture and ion concentration; Mid-to-high frequency (1kHz~1MHz): Current partially penetrates the root cell membrane, reflecting root biomass and structure (cell membrane integrity); High frequency (>1MHz): Current penetrates the cell interior, reflecting tissue water content. The first dual-axis motor drives two rotating rods and two threaded blocks to rotate via two transmission rods and multiple bevel gears. The rotation of the two threaded blocks on the inner walls of the two threaded sleeves drives the top plate to move up and down. The top plate drives multiple discharge electrodes and multiple measuring electrodes to move up and down. Two limiting grooves guide and limit the two sliding plates. Two vertical plates connect the screw and the limiting rod. The second dual-axis motor drives two screws to rotate. The rotation of the two screws drives the two sliding plates and two pins to move closer to each other, so that the two pins are inserted into the two pin grooves, thereby positioning the seedling box on the top of the base. The limiting rod guides and limits the two sliding plates. The controller can operate and control the first and second dual-axis motors. Attached Figure Description
