Description

Technical Field

[0001] This utility model relates to the field of soilless potato cultivation technology, and in particular to a soilless potato cultivation device with water oxygen detection function. Background Technology

[0002] Soilless potato cultivation is a novel planting technology that does not rely on traditional soil but instead uses artificially created environments such as hydroponics, aeroponics, and substrate cultivation to provide potatoes with the necessary water, nutrients, and air for growth. This technology eliminates soil limitations and can be carried out in controlled environments such as greenhouses, polytunnels, and indoors, offering advantages such as water conservation, fertilizer conservation, labor saving, high yield, and environmental friendliness. Furthermore, soilless potato cultivation requires real-time monitoring of dissolved oxygen levels in the water to ensure normal aerobic respiration of the roots, preventing root rot, nutrient absorption disorders, and diseases caused by oxygen deficiency, thus guaranteeing healthy plant growth and tuber development. However, conventional water oxygen detection typically uses direct probe measurement, which has the following shortcomings in practical applications:

[0003] On the one hand, potato roots and leaves fall into the nutrient solution, and their decomposition and microbial activities consume oxygen, polluting the detection probe and forming local oxygen-consuming micro-areas. Furthermore, the initial photosynthesis of leaves and respiration of roots cause data fluctuations, leading to deviations in water oxygen detection. On the other hand, dissolved oxygen in the same water body is spatially unevenly distributed. Single-point sampling is prone to measurement errors due to differences in the location and depth of the probe, making it impossible to accurately reflect the overall dissolved oxygen level. Utility Model Content

[0004] This invention proposes a soilless potato cultivation device with water oxygen detection function. By using an inclined plate to separate the liquid storage tank and guide the discharge of organic matter, and by coaxially arranging the stirring blade and the detection probe to form a three-dimensional vortex, the device completes the treatment of nutrient solution pollution and dissolved oxygen homogenization. This solves the problems of local oxygen-consuming micro-areas and uneven dissolved oxygen in space, and eliminates detection probe pollution and point measurement deviation. It achieves the purpose of improving dissolved oxygen detection accuracy and ensuring the oxygen supply environment for the roots, thereby solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a soilless potato cultivation device with water oxygen detection function, comprising a liquid storage tank and a fixing plate fixed to the bottom of the liquid storage tank, a planting device installed on the top of the liquid storage tank, an inclined plate and a sprinkler assembly inside the liquid storage tank, a detection device and a stirring device arranged sequentially from top to bottom on the outer wall of the liquid storage tank, and a liquid replenishment pipe penetrating the tank body on the other side wall, with a solenoid valve installed at the outer end of the liquid replenishment pipe;

[0006] The liquid storage tank includes a top cover, and a discharge port connected to one end and a side cover for closing the discharge port are provided on one side of the liquid storage tank.

[0007] The planting device includes a rotatable root cutting barrel. The top of the cutting barrel is connected to a positioning ring via a trapezoidal slider, and the bottom is provided with a mesh guide frame to prevent potatoes from splashing. The positioning ring and the top cover are elastically abutted by symmetrical springs.

[0008] The inclined plate extends to the discharge port on the side wall of the storage tank, which is sealed by a removable side cover.

[0009] Preferably, the planting device further includes a positioning plate that runs horizontally through the grid guide frame, with a waterproof cover above it. A first motor is installed inside the waterproof cover. A filter plate that rotates coaxially with the output shaft of the first motor is fixedly connected to the bottom of the root cutting bucket. The irrigation assembly includes a small water pump that runs through the edge of the inclined plate. The lower end of the small water pump is connected to an inlet pipe, and the upper end is connected to an outlet pipe. The upper end of the outlet pipe is connected to a liquid storage pipe. Both ends of the liquid storage pipe are fixedly abutted against the inner wall of the liquid storage tank through a first sealing cap. A plurality of water guide pipes are connected to one side of the liquid storage pipe. A plurality of connecting water guide pipes are connected to the upper end of the water guide pipes. Atomizing sprayers are provided on the connecting water guide pipes. The water guide pipes are fixed to the inner wall of the liquid storage tank through a second sealing cap.

[0010] Preferably, the minimum installation height of the liquid storage pipe and the water guide pipe is 15cm higher than the lowest point of the grid guide frame, and the water guide pipe is arranged laterally along the grouping gap of the planting device. The detection device includes an oxygen detector handle fixed to the outer wall of the liquid storage tank. The left end of the oxygen detector handle is connected to a cable, and the right end is fixedly installed with a detection probe that penetrates and extends into the liquid storage tank.

[0011] Preferably, the stirring device includes a motor base fixed to a fixed plate, a second motor is installed above the fixed plate, the output end of the second motor is connected to a rotating shaft, and a stirring blade is fixedly installed at one end of the rotating shaft that passes through and extends into the liquid storage tank. The stirring device and the right end of the detection device are kept horizontal.

[0012] Preferably, the inlet end of the replenishment pipe is located below the inclined plate and penetrates the side wall of the storage tank. The grid guide frame is set in groups of two, for a total of four groups, with an operating gap between each group for the water guide pipe to pass through.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. The storage tank is divided into upper and lower independent spaces by an inclined plate. Its inclined structure can guide the falling potato roots and leaves to slide along the plate surface to the discharge port, effectively blocking organic matter from entering the lower nutrient solution, avoiding decomposition oxygen consumption and probe contamination, thereby eliminating local oxygen consumption micro-area interference and improving the accuracy of dissolved oxygen detection data.

[0015] 2. This utility model utilizes a coaxial horizontal layout design of the stirring blade and the detection probe to force the mixing of the nutrient solution through the three-dimensional vortex generated by the rotation of the stirring blade. This promotes rapid convection between the upper and lower water layers and ensures uniform dissolved oxygen concentration, keeping the detection probe in the core flow field region with balanced dissolved oxygen. This fundamentally eliminates the measurement deviation caused by uneven oxygen content in the water space in traditional detection methods, ensuring that the detection data accurately reflects the overall dissolved oxygen level and providing a reliable basis for the regulation of root oxygen supply.

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Please see Figure 1 , Figure 2 As shown, a soilless potato cultivation device with water oxygen detection function includes a liquid storage tank 1 and a fixing plate 2 fixed to the bottom of the liquid storage tank. A planting device 3 is installed on the top of the liquid storage tank 1. An inclined plate 4 and a sprinkler assembly 5 are provided inside the liquid storage tank 1. A detection device 6 and a stirring device 7 are arranged from top to bottom on the outer wall of the liquid storage tank 1. A liquid replenishment pipe 8 is provided on the other side wall, penetrating the tank body. A solenoid valve 9 is installed at the outer end of the liquid replenishment pipe 8.

[0028] The liquid storage tank 1 includes a top cover 11, and a discharge port connected to one end of 4 and a side cover 12 for closing the discharge port are provided on one side of the liquid storage tank 1.

[0029] It should be specifically noted that the end of the inclined plate 4 extends to the discharge port on the side wall of the storage tank, and the discharge port is sealed by the removable side cover 12; the inlet end of the replenishment pipe 8 is located below the inclined plate 4 and penetrates the side wall of the storage tank 1. The inlet of the replenishment pipe is located below the inclined plate, which can avoid disturbing the upper liquid.

[0030] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the planting device 3 includes a rotatable root cutting barrel 33. The top of the cutting barrel is connected to a positioning ring 31 via a trapezoidal slider, and the bottom is provided with a grid guide frame 34 to prevent potatoes from splashing. The positioning ring 31 and the top cover 11 are elastically abutted by symmetrical springs 32. The planting device 3 also includes a positioning plate 35 that runs horizontally through the grid guide frame 34. A waterproof cover 36 is provided above the plate. A first motor 37 is installed inside the waterproof cover 36. A filter plate 38 that rotates coaxially with the output shaft of the first motor is fixedly connected to the bottom of the root cutting barrel 33. The surface of the filter plate 38 has filter holes with a diameter of 5 mm evenly distributed.

[0031] It should be specifically noted that when the first motor 37 drives the root cutting barrel 33 to rotate at high speed to cut the root system, the elastic deformation of the spring 32 can absorb the vibration energy generated during the cutting process, reducing the mechanical impact on the top cover 11 and the liquid storage tank 1. At the same time, the slight up-and-down vibration of the cutting barrel under the action of the spring can help separate the fine roots wrapped around the grid guide frame 34, improving the thoroughness of root cutting.

[0032] Please see Figure 3 , Figure 6 As shown, the sprinkler assembly 5 includes a small water pump 51, which passes through the edge of the inclined plate 4. The lower end of the small water pump 51 is connected to an inlet pipe 52, and the upper end of the pump 51 is connected to an outlet pipe 53. The upper end of the outlet pipe 53 is connected to a storage pipe 54. Both ends of the storage pipe 54 are fixedly abutted against the inner wall of the storage tank through a first sealing cap 55. A plurality of water guide pipes 56 are connected to one side of the storage pipe 54. A plurality of connecting water guide pipes 58 are connected to the upper end of the water guide pipes 56. Atomizing sprayers 59 are provided on the connecting water guide pipes 58. The water guide pipes 56 are fixed to the inner wall of the storage tank through a second sealing cap 57.

[0033] It should be specifically noted that the water pipe 56 is arranged horizontally along the gap between the groups of planting device 3. The minimum installation height of the liquid storage pipe 54 and the water pipe 56 is 15cm higher than the lowest point of the grid guide frame 34 to prevent the potatoes cut by the high-speed rotation of 33 from scattering in all directions and damaging the water pipes. The grid guide frame 34 is set in four groups of two, with an operating gap between each group for the water pipe 56 to pass through.

[0034] Please see Figure 1 , Figure 3 and Figure 5 As shown, the detection device 6 includes an oxygen detector handle 61 fixed to the outer wall of the storage tank. The left end of the oxygen detector handle 61 is connected to a cable 62, and the right end of the handle 61 is fixedly installed with a detection probe 63 that penetrates and extends into the interior of the storage tank 1.

[0035] Please see Figure 1 , Figure 3 and Figure 4As shown, the stirring device 7 includes a motor base 71 fixed to the fixing plate 2. A second motor 72 is installed above the fixing plate 71. The output end of the second motor 72 is connected to the fixing plate with a rotating shaft 73. The rotating shaft 73 passes through and extends into the liquid storage tank 1. A stirring blade 74 is fixedly installed at one end. The stirring device 7 and the right end of the detection device 6 are kept horizontal.

[0036] It should be specifically noted that the blades of the stirring blade 74 have a spiral curved surface structure. When rotating and stirring, they form a three-dimensional vortex in the nutrient solution, which promotes full convection between the upper and lower liquid layers and promotes the rapid and uniform distribution of dissolved oxygen concentration in the water.

[0037] Please see Figures 1-8 As shown, the working principle of the entire device in actual use is as follows:

[0038] Step 1, Initialization Phase: First, inject pre-prepared nutrient solution into the storage tank 1 through the replenishment pipe 8. The liquid level should cover the area below the inclined plate 4 and reach the monitoring height of the detection probe 63. Place the potato seed tubers into the root cutting bucket 33. Start the sprinkler assembly 5. The small water pump 51 draws nutrient solution from the bottom of the storage tank 1 through the inlet pipe 52, and delivers it to the storage pipe 54 through the outlet pipe 53. Then, through the guide pipe 56 and connecting guide pipe 58, the solution is evenly sprayed around the potato roots by the atomizing sprayer 59. The minimum installation height of the storage pipe 54 and the guide pipe 56 is 15cm higher than the lowest point of the grid guide frame.

[0039] Step 2, Daily Operation Stage: Insert the stirring device 7. The second motor 72 drives the rotating shaft 73 and stirring blades 74 to rotate at a constant speed. The spiral curved surface structure of the blades forms a three-dimensional vortex in the nutrient solution, promoting full convection between the upper and lower liquid layers. After continuous stirring for 2-3 minutes, the device enters a stable detection state. At this time, insert the detection device 6. The stirring blades 74 and the probe tip of the detection probe 63 are at the same horizontal position, ensuring that the uniformly mixed water flows preferentially through the detection area. The stirring device 7 forms a circulating flow field in the nutrient solution through the rotation of the stirring blades 74, promoting the rapid and uniform distribution of dissolved oxygen concentration in the water body, effectively eliminating the difference in oxygen content in different areas. When the detection device 6 monitors the treated water body, the dissolved oxygen data collected by its probe 63 can truly reflect the overall level, avoiding the measurement deviation caused by point differences in traditional detection. This collaborative working mode significantly improves the accuracy of dissolved oxygen detection and ensures the reliability and stability of monitoring results. When the detection data is within the normal range, the sprinkler assembly 5 works in a cycle according to the preset cycle to ensure that the roots continuously receive a moist nutrient environment. The water pipe 56 is arranged laterally along the gap of the planting device 3 to ensure that the roots in each set of grid guide frames 34 can be sprayed evenly.

[0040] Step 3, Harvesting Stage: After the potatoes mature, the first motor 37 drives the root cutting barrel 33 and the filter plate 38 to rotate, and the sharp edges cut off the root system. The elasticity of the spring 32 causes the cutting barrel to vibrate slightly when rotating, which helps to separate the remaining roots. The cut potatoes fall onto the inclined plate 4 through the grid guide frame 34. The inclined plate 4 guides the potatoes to move towards the discharge port. The side cover 12 is opened to remove all the potatoes.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
