Description

Technical Field

[0001] This invention belongs to the field of potato planting technology, specifically relating to a watering device for potato planting and its usage method. Background Technology

[0002] Potato cultivation refers to the process of planting potato seeds in the soil using scientific methods and suitable environmental conditions, allowing them to grow for a period of time, and ultimately harvesting potato tubers. Potato cultivation involves several key steps and technical aspects to ensure high yield and quality.

[0003] Reasonable water demand control is one of the important indicators for the normal growth and development of potatoes. For example, during the sprouting stage, potatoes mainly rely on the nutrients and water of the seed tuber for germination, and the water demand is relatively low. During the seedling stage, growth is small, with few branches and leaves, and water transpiration is also low, so the water demand is relatively low. During the vegetative growth stage, the stems, leaves, and roots grow vigorously, water transpiration increases, and the water demand increases. During the tuber formation stage, the water demand reaches its peak, and watering should be done frequently with small amounts to keep the soil consistently moist. During the starch accumulation stage, stem and leaf growth completely stops, and tubers begin to accumulate a large amount of dry matter, so the water demand decreases. During the harvest stage, the water demand continues to decrease, making harvesting easier. However, potatoes grown in existing greenhouses are generally watered manually. Manual watering makes it difficult to control the amount of water according to soil conditions or the potato growth cycle, which easily leads to problems of insufficient or excessive watering. This not only easily affects the normal growth of potatoes but also easily wastes water resources.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a watering device for potato cultivation and its usage method.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a watering device for potato cultivation and its usage method, which can solve the problem of inefficient watering of potatoes grown in greenhouses.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution:

[0008] A watering device for potato cultivation includes a monitoring unit, an intelligent decision-making unit, and a dynamic irrigation mechanism. The monitoring unit includes multiple sensors for modularly monitoring the humidity and nutrient levels of the potato planting plot. The intelligent decision-making unit issues instructions based on the monitoring results of the monitoring unit, and the dynamic irrigation mechanism receives the instructions and executes the actions.

[0009] The dynamic irrigation mechanism includes: a pair of supports, a mobile storage mechanism, and a water replenishment mechanism;

[0010] The bracket is installed on the ridge between a pair of adjacent plots of land, and a guide rail is installed between the pair of brackets.

[0011] The mobile storage mechanism is slidably connected to the guide rail, and the mobile storage mechanism is equipped with irrigation water and water-soluble fertilizer.

[0012] The water replenishment mechanism is connected to the mobile storage mechanism and is used to spray irrigation water onto the potatoes on the plot according to the instructions made by the intelligent decision-making unit.

[0013] In one or more embodiments of the present invention, the sensor includes a soil moisture sensor and a soil nutrient sensor, wherein the soil moisture sensor is used to monitor soil moisture within a plot area, and the soil nutrient sensor is used to monitor the nitrogen, phosphorus, and potassium content of the soil within the plot area.

[0014] In one or more embodiments of the present invention, the intelligent decision-making unit includes a signal receiving unit, a processing unit, an Internet of Things (IoT) unit, and an instruction output unit. The signal receiving unit is used to receive sensor signals, the processing unit is used to generate processing instructions based on monitoring results, the IoT unit is used to assist the processing unit in generating processing instructions, and the instruction output unit is used to send processing instructions to the dynamic irrigation mechanism.

[0015] In one or more embodiments of the present invention, a first screw and a guide rod are installed between a pair of brackets, and an electric motor is installed on one of the guide rails. The output end of the electric motor is connected to the first screw. When the electric motor is running, the electric motor can drive the first screw to rotate.

[0016] The mobile storage mechanism includes a storage box, on which a connector is fixedly connected. The connector is slidably connected to a guide rail and a guide rod, and is threadedly connected to a first screw. When the first screw rotates, the connector is threadedly connected to the first screw, and therefore, the connector is able to move on the guide rail and guide rod due to the thread action, so as to move the storage box to the corresponding planting plot that needs watering or fertilizer.

[0017] In one or more embodiments of the present invention, the storage box is provided with a water storage chamber, a fertilizer storage chamber and a mixing chamber. The water storage chamber is used to store irrigation water, the fertilizer storage chamber is used to store water-soluble fertilizer, and the mixing chamber is used to mix irrigation water and water-soluble fertilizer. A liquid pump is installed in the water storage chamber to extract irrigation water from the water storage chamber.

[0018] In one or more embodiments of the present invention, a fixing post is connected to the bottom of the storage box, and the fixing post is used to connect the annular disk;

[0019] The fixed column is connected to an annular disk at the end away from the storage box. The side wall of the annular disk is equipped with several spray heads. The water-soluble fertilizer solution in the mixing chamber will enter the annular disk and be sprayed onto the potato roots through the spray heads. Compared with spraying the water-soluble fertilizer solution onto the potato leaves and stems, this can accelerate the absorption of the water-soluble fertilizer solution by the potato, avoid waste of water-soluble fertilizer, and prevent the potato leaves and stems from being burned.

[0020] The fixed column is equipped with a conveying pipe, and the inside of the annular disk is connected to the mixing chamber through the conveying pipe. A first control valve is installed on the conveying pipe. When the first control valve is opened, the water-soluble fertilizer solution in the mixing chamber enters the annular disk through the conveying pipe.

[0021] In one or more embodiments of the present invention, a connecting pipe is connected between the water storage chamber and the fertilizer storage chamber. A three-way pipe is installed on the connecting pipe. A pair of fourth control valves and a pair of electromagnetic flow meters are installed on the connecting pipe. The fourth control valves correspond to the electromagnetic flow meters, and the pair of fourth control valves are respectively located on both sides of the three-way pipe. Irrigation water in the water storage chamber and water-soluble fertilizer in the fertilizer storage chamber will flow to the mixing pipe and the mixing chamber through the connecting pipe and the three-way pipe. The electromagnetic flow meters are used to detect the flow rate of irrigation water or water-soluble fertilizer so as to accurately control the concentration of water-soluble fertilizer solution in the mixing chamber and avoid the problem of insufficient or excessive nutrient supplementation in the future.

[0022] A mixing pipe is installed on the three-way pipe, and a liquid outlet is connected to the mixing pipe. The liquid outlet is located inside the mixing chamber, and a stirring element is installed inside the mixing pipe. The stirring element is used for preliminary mixing of irrigation water and water-soluble fertilizer.

[0023] In one or more embodiments of the present invention, the water replenishment mechanism includes a first fixing ring, which is connected to the outside of the fixing column and is used to connect a pair of straight pipes;

[0024] A pair of straight pipes are symmetrically connected to the first fixing ring. Several evenly distributed atomizing nozzles are installed on the straight pipes. Irrigation water in the straight pipes is sprayed out through the atomizing nozzles for atomized watering of potato leaves and stems.

[0025] An annular pipe is also provided on the outside of the fixed column. A fixed rod and a branch pipe are connected between the annular pipe and the straight pipe. The inside of the annular pipe is connected to the inside of the straight pipe through the branch pipe. A water delivery pipe is connected between the annular pipe and the output end of the pump. A second control valve and a third control valve are respectively installed on the branch pipe and the water delivery pipe. When the pump is running, it can draw irrigation water from the water storage chamber and then deliver it to the straight pipe through the water delivery pipe, the annular pipe and the branch pipe. The flow direction of the irrigation water in the annular pipe can be controlled by the second control valve, which can inject irrigation water into one or a pair of straight pipes. The specific control is based on the monitoring results of the sensor.

[0026] In one or more embodiments of the present invention, a rack is connected to the bottom wall of the guide rail, and a linkage stirring and discharging mechanism is installed in the storage box. The linkage stirring and discharging mechanism corresponds to the rack. When the moving storage mechanism moves on the guide rail to the plot where water-soluble fertilizer needs to be sprayed, the linkage stirring and discharging mechanism can stir and compress the water-soluble fertilizer solution in the mixing chamber, and spray it directly onto the potato roots through the annular disc to accelerate the absorption rate of the water-soluble fertilizer solution by the potatoes.

[0027] A method for using a watering device for potato cultivation includes the following steps:

[0028] S1. The potato planting plots in the greenhouse are divided into modular sections, and sensors are installed in each modular planting plot to monitor the moisture and nutrient levels of the planting plot.

[0029] S2. If the sensor in one of the planting plots detects that the soil moisture content is low, the sensor will transmit the monitoring data to the intelligent decision-making unit. The intelligent decision-making unit will generate a watering instruction based on the Internet of Things and send the instruction to the dynamic irrigation agency.

[0030] S3. When the dynamic irrigation mechanism executes the command, the storage box can move on the guide rail. When the storage box moves to the vicinity of the water-deficient planting plot, the pump in the water storage chamber runs, and the second control valve on the branch pipe on the side close to the water-deficient planting plot and the third control valve on the water delivery pipe are opened. The pump draws irrigation water from the water storage chamber and delivers the irrigation water to the straight pipe through the water delivery pipe, the ring pipe and the branch pipe. Then, through several atomizing nozzles, the water is atomized and replenished to the potato leaves and stems on the water-deficient planting plot. The atomized water replenishment range is the entire water-deficient planting plot.

[0031] S4. If the sensor in one of the planting plots detects low soil nutrient levels, the intelligent decision-making unit generates a fertilization instruction based on the Internet of Things and sends the instruction to the dynamic irrigation agency.

[0032] S5. When the dynamic irrigation mechanism executes the command, the storage box will also move to the vicinity of the nutrient-deficient planting plot. At the same time, a pair of fourth control valves on the connecting pipe will open. The irrigation water in the water storage chamber and the water-soluble fertilizer in the fertilizer storage chamber will enter the mixing pipe through the connecting pipe and the tee pipe. When the irrigation water or water-soluble fertilizer flows in the connecting pipe, the electromagnetic flow meter can measure the flow rate to control the concentration of the water-soluble fertilizer solution.

[0033] S6. Irrigation water and water-soluble fertilizer in the mixing pipe are initially mixed under the action of the agitator. Finally, they enter the mixing chamber through the liquid outlet for temporary storage. The storage tank continues to move on the guide rail. The linkage stirring and discharging mechanism is linked under the action of the rack and pinion to stir the water-soluble fertilizer solution in the mixing chamber again. It can also compress the water-soluble fertilizer solution in the mixing chamber.

[0034] S7. When the first control valve on the delivery pipe is opened, the mixed water-soluble fertilizer solution in the mixing chamber enters the annular disc through the delivery pipe, and then sprays the water-soluble fertilizer solution onto the potato roots on the corresponding nutrient-deficient planting plot through several spray heads. The water-soluble fertilizer solution replenishes the entire nutrient-deficient planting plot.

[0035] Compared with the prior art, the watering device and its usage method for potato planting of the present invention can perform dynamic and intelligent watering based on the soil condition in the greenhouse and the potato growth cycle, which can not only ensure the normal growth of potatoes, but also avoid the waste of water resources.

Detailed Implementation

[0052] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0053] like Figures 1 to 13 As shown, an irrigation device for potato planting in one embodiment of the present invention includes a monitoring unit, an intelligent decision-making unit, and a dynamic irrigation mechanism.

[0054] The monitoring unit includes multiple sensors, which modularly divide the potato planting plots within the greenhouse. Each planting plot is equipped with sensors to monitor humidity and nutrient levels. This application facilitates sensor monitoring and potato planting management by dividing the greenhouse planting plots into several modular plots.

[0055] In addition, the sensors include soil moisture sensors and soil nutrient sensors. The soil moisture sensor is used to monitor soil moisture within the plot area, and the soil nutrient sensor is used to monitor the nitrogen, phosphorus, and potassium content of the soil within the plot area. Moisture and nutrient levels within the module area can be monitored using these sensors.

[0056] Specifically, the intelligent decision-making unit issues instructions based on the monitoring results from the monitoring unit. The intelligent decision-making unit includes a signal receiving unit, a processing unit, an IoT unit, and an instruction output unit. The signal receiving unit receives sensor signals, the processing unit generates processing instructions based on the monitoring results, and the IoT unit assists the processing unit in generating these instructions. When the processing unit receives sensor signals, it sends a request to the IoT unit. The IoT unit then generates corresponding data information based on the existing potato growth cycle. After receiving the data information, the processing unit sends watering or fertilizing instructions to the instruction output unit. The instruction output unit sends processing instructions to the dynamic irrigation system.

[0057] In addition, the dynamic irrigation system receives instructions from the intelligent decision-making unit and performs corresponding actions, including watering or fertilizing a specific planting plot in the greenhouse. The amount of water and fertilizer applied also needs to be determined according to the instructions, which can prevent the potatoes from having insufficient or excessive water during their growth period.

[0058] like Figures 1 to 12 As shown, the dynamic irrigation mechanism includes: a pair of supports 1, a mobile storage mechanism 2, a water replenishment mechanism 3, a linkage mixing and discharging mechanism 4, and an evaporating water vapor collection mechanism 5.

[0059] Among them, the support 1 is installed on the ridge between a pair of adjacent plots, and a guide rail 101 is installed between the pair of support 1s. The guide rail 101 is distributed along the planting plots. When the mobile storage mechanism 2 moves on the guide rail 101, it can water or fertilize the potatoes on the planting plots on both sides of the guide rail 101 according to the instructions.

[0060] Additionally, a first screw and a guide rod are installed between a pair of brackets 1, and a motor 102 is mounted on one of the guide rails 101. The output end of the motor 102 is connected to the first screw. When the motor 102 is running, it can drive the first screw to rotate.

[0061] like Figures 1 to 12 As shown, the mobile storage mechanism 2 is slidably connected to the guide rail 101, and the mobile storage mechanism 2 is equipped with irrigation water and water-soluble fertilizer.

[0062] The mobile storage mechanism 2 includes a storage box 201, on which a connector 202 is fixedly connected. The connector 202 is slidably connected to the guide rail 101 and the guide rod, and is threadedly connected to the first screw. When the first screw rotates, because the connector 202 is threadedly connected to the first screw, the connector 202 is able to move on the guide rail 101 and the guide rod due to the thread action, so as to move the storage box 201 to the corresponding planting plot that needs watering or fertilization.

[0063] In addition, the storage box 201 is equipped with a water storage chamber 203, a fertilizer storage chamber 204 and a mixing chamber 205. The water storage chamber 203 is used to store irrigation water, the fertilizer storage chamber 204 is used to store water-soluble fertilizer, and the mixing chamber 205 is used to mix irrigation water and water-soluble fertilizer.

[0064] Specifically, a pump is installed inside the water storage chamber 203. The pump is used to extract irrigation water from the water storage chamber 203 so as to irrigate the planting plots that need watering.

[0065] like Figures 1 to 7 As shown, a fixing post 206 is connected to the bottom of the storage box 201, and the fixing post 206 is used to connect the annular disk 207. A pair of limiting plates 2061 are symmetrically connected to the side wall of the fixing post 206. The limiting plates 2061 are used to guide the up and down movement of the watering mechanism 3, so as to adjust the height of the watering mechanism 3 according to the height of the potato leaves and stems, so that the watering mechanism 3 can better water the potatoes.

[0066] The fixed column 206 is equipped with a conveying pipe 2062, and the annular disk 207 is connected to the mixing chamber 205 through the conveying pipe 2062. A first control valve is installed on the conveying pipe 2062. When the first control valve is opened, the water-soluble fertilizer solution in the mixing chamber 205 enters the annular disk 207 through the conveying pipe 2062.

[0067] In addition, an annular disk 207 is connected to the end of the fixed column 206 away from the storage box 201, and several spray heads 2071 are provided on the side wall of the annular disk 207. The water-soluble fertilizer solution in the mixing chamber 205 will enter the annular disk 207 and be sprayed onto the potato roots through the spray heads 2071. Compared with spraying the water-soluble fertilizer solution onto the potato leaves and stems, this application can accelerate the absorption rate of the water-soluble fertilizer solution by the potato, while also avoiding waste of water-soluble fertilizer and preventing the potato leaves and stems from being burned.

[0068] like Figures 1 to 12 As shown, a peristaltic pump is installed in the fertilizer storage chamber 204. A connecting pipe 208 is connected between the water storage chamber 203 and the fertilizer storage chamber 204. The connecting pipe 208 is connected to the output end of the peristaltic pump. The peristaltic pump is used to extract water-soluble fertilizer from the fertilizer storage chamber 204.

[0069] The connecting pipe 208 is equipped with a three-way pipe 209, and a pair of fourth control valves and a pair of electromagnetic flow meters are installed on the connecting pipe 208. The fourth control valves correspond to the electromagnetic flow meters, and the pair of fourth control valves are respectively located on both sides of the three-way pipe 209.

[0070] Irrigation water in water storage chamber 203 and water-soluble fertilizer in fertilizer storage chamber 204 flow to mixing pipe 210 and mixing chamber 205 through connecting pipe 208 and tee pipe 209. Electromagnetic flow meter is used to detect the flow rate of irrigation water or water-soluble fertilizer so as to accurately control the concentration of water-soluble fertilizer solution in mixing chamber 205 and avoid problems of insufficient or excessive nutrient supplementation in the future.

[0071] In addition, a mixing pipe 210 is installed on the three-way pipe 209, and a liquid outlet 2101 is connected to the mixing pipe 210. The liquid outlet 2101 is located in the mixing chamber 205, and a stirring element 2102 is installed inside the mixing pipe 210. When irrigation water and water-soluble fertilizer enter the mixing pipe 210, they are initially mixed by the stirring element 2102.

[0072] like Figures 1 to 12 As shown, the water replenishment mechanism 3 is connected to the mobile storage mechanism 2. The water replenishment mechanism 3 is used to water the planting plots that need watering according to the watering instructions made by the intelligent decision-making unit.

[0073] The water supply mechanism 3 includes a first fixing ring 301, which is connected to the outside of the fixing post 206 and is used to connect a pair of straight pipes 302. A pair of straight pipes 302 are symmetrically connected to the first fixing ring 301, and several evenly distributed atomizing nozzles 303 are installed on the straight pipes 302. Irrigation water in the straight pipes 302 is sprayed out through the atomizing nozzles 303 for atomized watering of potato leaves and stems.

[0074] In addition, a pair of mounting plates 304 are installed on the outer wall of the storage box 201. A first adjusting electric cylinder 305 is installed on the mounting plate 304, and the free end of the first adjusting electric cylinder 305 is connected to the straight pipe 302. By setting the first adjusting electric cylinder 305, the height of the straight pipe 302 can be flexibly adjusted according to the height of the potato leaves and stems, so that the atomizing nozzle 303 can better water the potato leaves and stems.

[0075] Specifically, an annular pipe 306 is provided on the outside of the fixed column 206. A fixed rod 307 and a branch pipe 308 are connected between the annular pipe 306 and the straight pipe 302. The inside of the annular pipe 306 is connected to the inside of the straight pipe 302 through the branch pipe 308. A water delivery pipe 309 is connected between the annular pipe 306 and the output end of the liquid pump. A second control valve and a third control valve are respectively installed on the branch pipe 308 and the water delivery pipe 309.

[0076] When the pump is running, it draws irrigation water from the storage chamber 203 and delivers it through the water supply pipe 309, the ring pipe 306, and the branch pipe 308 to the straight pipe 302, finally discharging it through the atomizing nozzle 303. The flow direction of the irrigation water in the ring pipe 306 can be controlled by a second control valve, allowing it to flow into one straight pipe 302 or simultaneously into a pair of straight pipes 302. This control is based on sensor monitoring results, thus preventing irrigation water waste.

[0077] like Figures 1 to 12 As shown, a rack 103 is connected to the bottom wall of the guide rail 101. A linkage stirring and discharging mechanism 4 is installed inside the storage box 201. The linkage stirring and discharging mechanism 4 corresponds to the rack 103. When the moving storage mechanism 2 moves on the guide rail 101 to the plot where water-soluble fertilizer needs to be sprayed, the linkage stirring and discharging mechanism 4 can stir and compress the water-soluble fertilizer solution in the mixing chamber 205 under the action of the rack 103, and spray the water-soluble fertilizer solution directly onto the potato roots through the annular disk 207 to accelerate the absorption rate of the water-soluble fertilizer solution by the potato.

[0078] The linkage stirring and discharging mechanism 4 includes a rotating shaft 401, which is rotatably connected to the storage tank 201. A gear 402 and a first helical gear 403 are respectively connected to both ends of the rotating shaft 401, with the gear 402 corresponding to the rack 103. When the storage tank 201 moves on the guide rail 101, the gear 402 rotates under the action of the rack 103, thereby driving the first helical gear 403 to rotate via the rotating shaft 401.

[0079] Additionally, a linkage shaft 404 is rotatably connected inside the storage tank 201. The linkage shaft 404 connects the second helical gear 407, the extrusion plate 410, and the stirring plate 411. A linkage seat 405 is connected to one end of the linkage shaft 404 near the rotating shaft 401. A polygonal column 406 is slidably connected within the linkage seat 405. By sliding the polygonal column 406 within the linkage seat 405, the distance between the second helical gear 407 and the first helical gear 403 can be adjusted to control the up-and-down movement of the extrusion plate 410 and the rotation of the stirring plate 411.

[0080] Specifically, a second helical gear 407 is connected to the polygonal column 406, and the second helical gear 407 corresponds to the first helical gear 403. When the second helical gear 407 contacts the first helical gear 403, if the first helical gear 403 rotates, the first helical gear 403 can drive the second helical gear 407 to rotate, which in turn can drive the polygonal column 406, the linkage seat 405 and the linkage shaft 404 to rotate.

[0081] Furthermore, a second fixing ring 408 is connected to the side wall of the polygonal column 406, and a pair of second adjusting electric cylinders 409 are installed on the linkage seat 405. The free end of the second adjusting electric cylinder 409 is connected to the second fixing ring 408. By extending and retracting the second adjusting electric cylinder 409, the polygonal column 406 can slide within the linkage seat 405, thereby controlling the distance between the second helical gear 407 and the first helical gear 403, that is, controlling whether the first helical gear 403 contacts the second helical gear 407.

[0082] like Figures 1 to 12 As shown, one end of the linkage shaft 404 located in the mixing chamber 205 is threadedly connected to the extrusion plate 410. When the linkage shaft 404 rotates, the extrusion plate 410 is able to move in the mixing chamber 205 due to the thread action. If the extrusion plate 410 moves downward in the mixing chamber 205, it can compress the water-soluble fertilizer solution in the mixing chamber 205 so that the water-soluble fertilizer solution can enter the annular disk 207 through the delivery pipe 2062 and then be discharged through the spray head 2071.

[0083] The extrusion plate 410 is equipped with an injection port, and one end of the outlet head 2101 can be inserted into the injection port. Irrigation water and water-soluble fertilizer in the mixing pipe 210 can enter the mixing chamber 205 through the outlet head 2101 and the injection port, and are located on the lower side of the extrusion plate 410.

[0084] In addition, a pair of sliding columns 4101 are slidably connected to the extrusion plate 410. One end of each sliding column 4101 is connected to a sealing plate 4102, which is located below the extrusion plate 410 and can cover the injection port. When the extrusion plate 410 moves downward in the mixing chamber 205, the sealing plate 4102 can cover the injection port under the action of the elastic sleeve. At this time, the extrusion plate 410 can compress the water-soluble fertilizer solution in the mixing chamber 205 to facilitate the discharge of the water-soluble fertilizer solution.

[0085] Specifically, the other end of the sliding column 4101 is connected to a limiting ring 4103, which surrounds the liquid outlet head 2101. The limiting ring 4103 is used to limit the sealing plate 4102, preventing the sealing plate 4102 from detaching from the extrusion plate 410. A pair of elastic sleeves are provided between the limiting ring 4103 and the extrusion plate 410, and the pair of elastic sleeves are respectively located on the outside of the pair of sliding columns 4101. The elastic sleeves are used to apply an elastic force to the limiting ring 4103. When the sealing plate 4102 is not squeezed by the top column 2103, the sealing plate 4102 can cover the injection port, so that the water-soluble fertilizer solution in the mixing chamber 205 can be compressed by the downward extrusion plate 410.

[0086] In addition, a top column 2103 is installed inside the liquid outlet 2101, which can pass through the liquid inlet and contact the sealing plate 4102. When the liquid outlet 2101 passes through the liquid inlet, the top column 2103 can squeeze the sealing plate 4102, causing the sealing plate 4102 to detach from its cover on the liquid inlet, so that the irrigation water and water-soluble fertilizer in the mixing pipe 210 can enter the mixing chamber 205.

[0087] Furthermore, a stirring plate 411 is also connected to the side wall of the linkage shaft 404, and the stirring plate 411 is located inside the mixing chamber 205. When the linkage shaft 404 rotates, it can drive the stirring plate 411 to rotate. The rotating stirring plate 411 can stir the water-soluble fertilizer solution in the mixing chamber 205, preventing clumping in the water-soluble fertilizer solution and ensuring the subsequent fertilization effect.

[0088] like Figures 1 to 12 As shown, a transpiration water vapor collection mechanism 5 is installed on the guide rail 101. Potatoes grown in the greenhouse will undergo transpiration. During transpiration, some of the water absorbed by the potatoes will be lost to the atmosphere in the form of water vapor. The transpiration water vapor collection mechanism 5 can collect and utilize the water vapor generated during the transpiration of the potatoes for supplementary irrigation.

[0089] The evaporating water vapor collection mechanism 5 includes a base 501, on which a mounting seat 502 is fixedly connected. The mounting seat 502 is used to install a second screw 503, a slide bar 504, and a drive motor 505.

[0090] In addition, a second screw 503 is rotatably connected to the mounting base 502. The second screw 503 has opposite external threads on its outer side, and several sliding rods 504 are fixedly connected to the mounting base 502. When the second screw 503 rotates, it can drive the fixing plate 506 to move, thereby allowing the folding curtain 507 to be folded or unfolded. The sliding rods 504 can guide the movement of the fixing plate 506 and ensure the stability of the movement of the fixing plate 506.

[0091] Specifically, a drive motor 505 is mounted on the mounting base 502, and a belt connects the output end of the drive motor 505 to the second screw 503. When the drive motor 505 is running, it can drive the second screw 503 to rotate via the belt. Since the second screw 503 is threadedly connected to the fixing plate 506, the fixing plate 506 can move along the slide bar 504.

[0092] In addition, a fixing plate 506 is slidably connected between multiple sliding rods 504, and the fixing plate 506 is threadedly connected to the second screw 503. The fixing plate 506 is used to install the folding curtain 507. When the fixing plate 506 moves away from the mounting base 502, the folding curtain 507 is pulled open, i.e. Figure 9In the state shown, the unfolded folding curtain 507 is positioned above the potato. When the potato transpires, the water vapor can come into contact with the metal sheet connected to the folding curtain 507, causing the water vapor to liquefy. When the fixing plate 506 approaches the mounting base 502, the folding curtain 507 is folded, i.e. Figure 1 As shown in the diagram, the folding curtain 507 will not block sunlight, thus avoiding any impact on potato photosynthesis and ensuring normal potato production.

[0093] like Figures 1 to 12 As shown, a folding curtain 507 is connected between the base 501 and the fixing plate 506. The folding curtain 507 is used to install several metal pieces. Several metal pieces are connected to the bottom surface of the folding curtain 507. The metal pieces are divided into several blocks, so as not to affect the folding and unfolding of the folding curtain 507.

[0094] Preferably, the metal sheet can be fixed to the lower surface of the folding curtain 507 in an adhesive manner. When water vapor comes into contact with the metal sheet, it can liquefy to form droplets, which can be used to collect the water during potato transpiration and avoid water waste.

[0095] The base 501 has a collection chamber 508, which is used to collect droplets and also to mount the winding roller 509.

[0096] In addition, a pair of winding rollers 509 are rotatably connected inside the collection chamber 508. A spiral spring is connected between the winding rollers 509 and the inner wall of the collection chamber 508. When the water-blocking and breathable membrane 510 is not pulled, the collection chamber 508 can rotate and rewind the water-blocking and breathable membrane 510 under the action of the spiral spring, so as to avoid the water-blocking and breathable membrane 510 from being messy.

[0097] Specifically, a water-repellent and breathable membrane 510 is wound on the winding roller 509, and one end of the water-repellent and breathable membrane 510 is connected to the fixed plate 506, i.e. Figure 11 As shown in the diagram, the water vapor produced during potato transpiration can pass through the water-retaining and breathable membrane 510, while the droplets produced during water vapor liquefaction cannot pass through the water-retaining and breathable membrane 510 and slide along the water-retaining and breathable membrane 510 into the collection chamber 508 for collection.

[0098] In addition, a drain pipe 511 is connected to the base 501, and a temporary storage box 211 is installed on the storage box 201. The temporary storage box 211 corresponds to the drain pipe 511, and a return pipe is connected between the temporary storage box 211 and the water storage chamber 203. A fifth control valve is installed on the return pipe. The droplets collected in the collection chamber 508 can enter the temporary storage box 211 through the drain pipe 511, and then enter the water storage chamber 203 through the return pipe to replenish the irrigation water in the water storage chamber 203.

[0099] Furthermore, a sterilization lamp is installed inside the temporary storage tank 211 to sterilize and disinfect the collected water inside. A protective plate is installed on the upper side of the sterilization lamp to protect it from the influence of the collected water.

[0100] At night, the drive motor 505 can be controlled to run. The drive motor 505 drives the second screw 503 to rotate via a belt. Since the fixing plate 506 is threadedly connected to the second screw 503, controlling the pair of fixing plates 506 to move away from each other causes the folding curtain 507 to be pulled open, and the water-blocking and breathable membrane 510 is also pulled open. Figure 9 and Figure 11 The state shown.

[0101] Water vapor produced by potatoes during nighttime transpiration can pass through the water-repellent and breathable membrane 510 and come into contact with several metal sheets on the underside of the folding curtain 507. The water vapor liquefies upon contact with the metal sheets, forming droplets. These droplets fall onto the water-repellent and breathable membrane 510. Since the liquid cannot pass through the membrane, the droplets slide down along it and are collected in the collection chamber 508. The liquid collected in the collection chamber 508 flows through the drain pipe 511 into the temporary storage tank 211, and after being sterilized by the sterilizing lamp, it finally flows through the return pipe into the water storage chamber 203.

[0102] During the day, the drive motor 505 is operated, and the drive motor 505 drives the second screw 503 to rotate in the opposite direction via a belt, causing a pair of fixed plates 506 to move closer to each other. At this time, the folding curtain 507 is folded, and the collection chamber 508 can roll up the water-blocking and breathable membrane 510 under the action of the spiral spring, so that the water-blocking and breathable membrane 510 is also rolled up. Figure 1 The state shown is such that the folding curtain 507 and the water-blocking and breathable membrane 510 will not block sunlight, and therefore will not affect the photosynthesis of potato leaves and stems.

[0103] A method for using a watering device for potato cultivation includes the following steps:

[0104] S1. The potato planting plots in the greenhouse are divided into modular sections. The modular sections are recorded in the intelligent decision-making unit in the form of point coordinates. Each modular section is equipped with a soil moisture sensor and a soil nutrient sensor, and the sensors correspond to the point coordinates of the planting plot.

[0105] S2. If the soil moisture sensor of one of the planting plots detects that the soil moisture content is low, the sensor will transmit the monitoring data to the intelligent decision-making unit. The intelligent decision-making unit will generate a corresponding watering instruction based on the Internet of Things. The watering instruction includes the coordinates of the planting plot and the amount of water to be watered, and will send the instruction to the dynamic irrigation mechanism.

[0106] S3. When the dynamic irrigation mechanism executes the command, when the storage box 201 moves to the vicinity of the water-deficient planting plot according to the coordinate command, the pump in the water storage chamber 203 runs, and the second control valve on the branch pipe 308 and the third control valve on the water delivery pipe 309 on the side close to the water-deficient planting plot are opened. The pump draws irrigation water from the water storage chamber 203 and delivers the irrigation water to the straight pipe 302 through the water delivery pipe 309, the ring pipe 306 and the branch pipe 308. Then, the irrigation water is atomized and replenished to the potato leaves and stems on the water-deficient planting plot through several atomizing nozzles 303. The atomized water replenishment range is the entire water-deficient planting plot.

[0107] S4. If the soil nutrient sensor of one of the planting plots detects that the soil nutrient level is low, the intelligent decision-making unit generates a fertilization instruction based on the Internet of Things. The fertilization instruction includes the fertilization coordinates, the amount of fertilizer, and the concentration of water-soluble fertilizer solution, and sends the instruction to the dynamic irrigation agency.

[0108] S5. When the dynamic irrigation mechanism executes the command, the storage box 201 will also move to the vicinity of the nutrient-deficient planting plot according to the coordinate command. At the same time, a pair of fourth control valves on the connecting pipe 208 will open, and the irrigation water in the water storage chamber 203 and the water-soluble fertilizer in the fertilizer storage chamber 204 will enter the mixing pipe 210 through the connecting pipe 208 and the three-way pipe 209. When the irrigation water or water-soluble fertilizer flows in the connecting pipe 208, the electromagnetic flow meter can measure the flow rate to accurately control the concentration of the water-soluble fertilizer solution.

[0109] S6. Irrigation water and water-soluble fertilizer in mixing pipe 210 are initially mixed under the action of stirring component 2102. Finally, they enter the mixing chamber 205 for temporary storage through liquid outlet 2101. The second regulating electric cylinder 409 is extended, so that the second helical gear 407 contacts the first helical gear 403. When storage box 201 continues to move on guide rail 101, gear 402 rotates under the action of rack 103. Gear 402 drives the first helical gear 403 to rotate through rotating shaft 401. The first helical gear 403 drives the polygonal column 406, linkage seat 405 and linkage shaft 404 to rotate through second helical gear 407, thereby causing stirring plate 411 to rotate. The rotating stirring plate 411 is used to stir the water-soluble fertilizer solution in mixing chamber 205 again. At the same time, the extrusion plate 410 can move down in mixing chamber 205 under the action of the thread, thereby compressing the water-soluble fertilizer solution in mixing chamber 205.

[0110] S7. When the first control valve on the delivery pipe 2062 is opened, the water-soluble fertilizer solution mixed in the mixing chamber 205 enters the annular disc 207 through the delivery pipe 2062, and then sprays the water-soluble fertilizer solution onto the potato roots on the corresponding nutrient-deficient planting plot through several spray heads 2071. The water-soluble fertilizer solution replenishes the entire nutrient-deficient planting plot.
