Description

Technical Field

[0001] The present invention relates to the technical field of citrus cultivation, and particularly relates to an irrigation device for citrus cultivation and an irrigation method thereof. Background Art

[0002] Citrus belongs to the plants under the Rutaceae family, and prefers a warm and humid climate. Its cold tolerance is slightly stronger than that of pomelo, sour orange, and sweet orange. Currently, when irrigating citrus cultivation, flood irrigation is mostly used for irrigation. However, in the plantation, in order to ensure the foliage extension of citrus trees, the spacing between adjacent citrus trees usually needs to be ensured during planting, resulting in low irrigation efficiency.

[0003] Chinese Patent Document CN116724739A discloses an irrigation device for citrus cultivation and an irrigation method thereof, including a planting base. The upper surface of the planting base is fixedly connected with a planting side frame. The upper end of the planting base is rotatably installed with a planting component. The planting component includes a gear disk rotatably installed on the upper surface of the planting base and a rotating shaft fixedly connected to one end of the middle part of the gear disk. The outer surface of the rotating shaft is fixedly sleeved with a planting roller. The upper end of the planting base is installed with a conveying component. A mixed liquid feeding hopper is inserted through the top of the planting side frame. The upper end of the planting side frame is fixedly installed with a driving component. The upper part of the bottom end of the planting side frame is rotatably installed with a traction component. The upper part of the planting side frame is fixedly connected with a liquid medicine transfer component, which is beneficial to improving the absorption efficiency and dosage of the root system and the overall irrigation quality when irrigating and fertilizing, and enabling the liquid medicine to penetrate into the soil layer of the citrus root system.

[0004] However, when the device is actually used, manual mixing is required, and the ratio cannot be accurately controlled, increasing the risk of citrus root burning or insufficient drug efficacy. Moreover, it cannot control the drug ratio in different proportions according to different varieties and growth cycles, and the practicability of the device is relatively poor. Summary of the Invention

[0005] The main purpose of the present invention is to provide an irrigation device for citrus cultivation and an irrigation method thereof, which can effectively solve the problems of relatively high risks of citrus root burning or insufficient drug efficacy and relatively poor practicability.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] An irrigation device for citrus cultivation includes a crawler base. A water tank, a water pump, a medicine preparation component, and a plurality of medicine tanks are fixed on the upper end of the crawler base. The medicine preparation component is connected to the plurality of medicine tanks through a connecting pipe;

[0008] The dispensing component includes a sealing plate fixed to the upper end of the crawler base. A horizontally arranged mixing pipe is provided inside the sealing plate. A plurality of feed pipes communicating with the inside of the mixing pipe are also provided at the upper end of the sealing plate. The feed pipes are connected to the connecting pipes. A guiding groove is also provided on one side of the mixing pipe close to the water pump. A spray head is provided at one end of the sealing plate away from the water pump.

[0009] Preferably, the end of the connecting pipe away from the feed pipe is located at the lower part of the medicine box, and a plurality of air holes are also provided at the upper end of the medicine box.

[0010] Preferably, a valve and a check valve are also provided in the middle of the connecting pipe, and the check valve is located at one end of the valve close to the connecting pipe.

[0011] Preferably, a plurality of protrusions are provided on the inner surface of the guiding groove, a plurality of flow guiding plates are fixed to the inner walls of the plurality of guiding grooves, and a plurality of through holes are also provided in the upper part of the inner surface of the guiding groove.

[0012] The present invention also discloses a method for irrigating citrus using the above-mentioned irrigation device for citrus planting, and the specific steps are as follows:

[0013] S1. Preparation stage: Filling of medicine and water;

[0014] S2. Irrigation stage: Mixing of medicine and discharging of air;

[0015] S3. End and maintenance stage: Shut-down operation and daily maintenance.

[0016] Preferably, the preparation stage specifically includes the following steps:

[0017] A1. Medicine pretreatment: Filling different medicines according to different varieties of citrus;

[0018] A2. Ratio parameter adjustment: Adjusting the opening and closing angle of the valve according to the ratio of the medicine;

[0019] A3. Water source preparation: Filling the water tank with filtered clean water.

[0020] Preferably, the irrigation stage specifically includes the following steps:

[0021] B1. Device positioning and start-up;

[0022] B2. Automatic air discharge;

[0023] B3. Active mixing.

[0024] Preferably, the end and maintenance stage specifically includes the following steps:

[0025] C1. Shut-down operation: Closing the water pump and emptying all the water in the pipeline;

[0026] C2. Pipeline cleaning: Rinse the residual chemicals on the inner wall of the pipeline with clean water;

[0027] C3. Daily maintenance: Check whether the connecting pipes, valves and through holes are blocked and clean them.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Based on Bernoulli's principle, the present invention realizes the dynamic automatic adjustment of the chemical inhalation amount through the linkage of the water flow velocity and the pressure difference. The faster the water flow velocity, the more chemicals are inhaled, ensuring the real-time and accurate ratio of water and chemicals without manual intervention, solving the problem of uneven chemical concentration in traditional irrigation, and reducing the risk of citrus root burning or insufficient drug efficacy caused by misproportioning.

[0030] 2. The present invention can simultaneously fill multiple chemicals through multiple independent chemical tanks and a regulating valve, and accurately control the mixing ratio of different chemicals through the opening degree of the regulating valve, flexibly adapting to the personalized irrigation requirements of different varieties such as Wogan and Satsuma mandarin, and different growth periods such as the fruit swelling period and the flower preservation period, avoiding the problems of too strong or too dilute chemicals.

[0031] 3. The present invention is provided with a diversion plate and a through hole in the guiding groove at the front end of the mixing pipe, and automatically discharges the air entrained in the water flow by using the air density difference, avoiding the influence of air bubbles on the pressure difference and chemical proportioning. At the same time, the design of a one-way valve is adopted to prevent the water in the mixing pipe from flowing back into the chemical tank medicine box to dilute the chemicals, ensuring the stability of the chemical concentration and prolonging the effective preservation time of the chemicals.

[0041] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0042] Embodiment 1

[0043] As Figure 1 - Figure 4 shown, an irrigation device for citrus planting includes a crawler base 1, which adapts to the complex terrain of the citrus orchard to ensure the movement stability of the device. A water tank 2, a water pump 3, a chemical dosing assembly 4 and a plurality of chemical tanks 5 are fixed on the upper end of the crawler base 1. The chemical dosing assembly 4 and the plurality of chemical tanks 5 are connected by a connecting pipe 6.

[0044] As Figure 3 shown, the chemical dosing assembly 4 includes a sealing plate 41 fixed on the upper end of the crawler base 1. A horizontally arranged mixing pipe 42 is provided inside the sealing plate 41. The mixing pipe 42 is connected to the output end of the water pump 3, so that the water in the water tank 2 can be transmitted into the mixing pipe 42. A plurality of feed pipes 43 communicating with the inside of the mixing pipe 42 are also provided on the upper end of the sealing plate 41. The feed pipes 43 are connected to the connecting pipe 6. A spray head is also provided at one end of the sealing plate 41 away from the water pump 3. One end of the connecting pipe 6 away from the feed pipe 43 is located at the lower part of the chemical tank 5, so that the chemical agent in the chemical tank 5 can be transmitted into the mixing pipe 42 through the pressure difference between the feed pipe 43 and the mixing pipe 42, reducing the waste of the chemical agent. A plurality of ventilation holes are also provided on the upper end of the chemical tank 5. The ventilation holes can make the air pressure inside the connecting pipe 6 the same as the external pressure to ensure the stable operation of the device.

[0045] Furthermore, in order to stabilize the water flow in the mixing pipe 42, a guide groove 44 is also provided on one side of the mixing pipe 42 close to the water pump 3. Since the water pump 3 may transmit air into the mixing pipe 42 when transporting water, if there is air in the mixing pipe 42, it will affect the pressure difference between the mixing pipe 42 and the feed pipe 43, thus affecting the stable ratio of the chemical agent. As Figure 5 shown, the connection part between the water pump 3 and the water tank 2 is located at the lower part, so very little air is transmitted into the mixing pipe 42 when the water pump 3 transports water. Therefore, the design of the guide groove 44 can make the device more stable during use.

[0046] When the water pump 3 is working, it pumps the water in the water tank 2 into the medicine dispensing assembly 4 and transmits the water through the mixing pipe 42. When there is water flowing in the mixing pipe 42, due to the relatively fast water flow rate in the mixing pipe 42, according to Bernoulli's principle, the pressure is low where the flow rate is high. At this time, the pressure in the mixing pipe 42 will be less than the pressure in the feed pipe 43. Under the action of the pressure difference, the water in the medicine tank 5 is pushed by the atmospheric pressure towards the feed pipe 43 and then flows into the mixing pipe 42, realizing the process of water entering the mixing pipe 42 from the medicine tank 5 through the feed pipe 43. Due to the design of the medicine being contained in the medicine tank 5, the device can automatically adjust the amount of medicine according to the water flow rate, so that the ratio of water to medicine is always the same (the faster the water flow rate, the smaller the pressure in the mixing pipe 42, and the more medicine enters the mixing pipe 42; the slower the water flow rate, the greater the pressure in the mixing pipe 42, and the less medicine enters the mixing pipe 42).

[0047] As Figure 2 and Figure 4 shown, a valve 7 and a check valve 8 are also provided in the middle of the connecting pipe 6. Due to the design of the valve 7, the amount of medicine passing through the feed pipe 43 can be adjusted. Since the pressures in multiple feed pipes 43 are the same when the device is in use, the amount of medicine passing through the feed pipe 43 can be adjusted by adjusting the opening degree of the valve 7. Through the mutual cooperation between multiple valves 7, the amounts of different medicines entering the mixing pipe 42 can be adjusted, which can be applied to the cultivation of different varieties of citrus. The check valve 8 is located at one end of the valve 7 close to the connecting pipe 6, which can prevent the water in the mixing pipe 42 from flowing back into the connecting pipe 6 when the water pump 3 stops working, thereby reducing the concentration of the medicine and affecting the ratio of the medicine.

[0048] The specific implementation manner of this embodiment is as follows: When the device is in use, different medicines are first poured into different medicine tanks 5 respectively, then the valve 7 is adjusted according to the ratio of the medicines, and then the water tank 2 is filled with the water to be irrigated. The device is moved to the required position, and the crawler base 1 is controlled to move back and forth so that the device can irrigate more citrus.

[0049] When the device is moved to the position where it is to be used, the water pump 3 is started. When the water pump 3 is working, it pumps the water in the water tank 2 to the medicine dispensing assembly 4 and transmits it through the mixing pipe 42. According to Bernoulli's principle, the water flow rate in the mixing pipe 42 is fast and the pressure is low, and the pressure in the feed pipe 43 is greater than that in the mixing pipe 42. The medicine in the medicine tank 5 flows into the mixing pipe 42 through the feed pipe 43 under the action of the pressure difference, realizing the automatic adjustment of the ratio of the medicine with the water flow rate. The guiding groove 44 is used to stabilize the water flow in the mixing pipe 42. Since air may be brought in when the water pump 3 transports water, which affects the pressure difference, the design of the guiding groove 44 makes the device operate more stably. The valve 7 can adjust the amount of medicine passing through the feed pipe 43. The cooperation of multiple valves 7 can adjust the amounts of different medicines entering the mixing pipe 42 for different varieties of citrus. The check valve 8 can prevent the water in the mixing pipe 42 from flowing back into the connecting pipe 6 when the water pump 3 stops working, avoiding reducing the medicine concentration and affecting the ratio.

[0050] Example Two

[0051] This embodiment further improves the guiding groove 44 on the basis of Embodiment One, enabling the device to discharge the air in the water during use.

[0052] As Figure 5 shown, a plurality of protrusions 441 are provided on the inner surface of the guiding groove 44. The plurality of protrusions 441 can increase the friction between the water flow and the guiding groove 44, and can effectively suppress the turbulence and vortex of the water flow without significantly increasing the water flow resistance, making the water flow more stable. A plurality of flow guiding plates 442 are also fixed on the inner walls of the plurality of guiding grooves 44. The plurality of guiding grooves 44 are in a spiral rib shape, which can guide the water flow to flow in a predetermined direction, further reducing the turbulence and vortex of the water flow. A plurality of through holes 443 are also provided in the upper part of the inner surface of the guiding groove 44. The plurality of through holes 443 can timely discharge the air entrained in the water flow, avoiding the air entering the mixing pipe 42 and affecting the pressure difference and the chemical agent ratio.

[0053] In addition, since the guiding groove 44 is provided on one side of the mixing pipe 42 close to the water pump 3, and the connection between the water pump 3 and the water tank 2 is located at the lower part, this makes it very rare for air to be transmitted into the mixing pipe 42 when the water pump 3 conveys water. Even if a small amount of air enters, due to the lower density of air than water, it will gather in the upper part of the mixing pipe 42, and the position of the guiding groove 44 allows the air to pass through the through holes 443 preferentially, while the water will continue to flow along the mixing pipe 42 below due to the action of gravity and will not easily enter the through holes 443 and be discharged.

[0054] Example Three

[0055] This embodiment makes a detailed supplementary description of the irrigation method of the citrus planting irrigation device on the basis of Embodiment One and Embodiment Two, as Figure 6 shown.

[0056] S1. Preparation stage:

[0057] A1. Chemical agent pretreatment. Different chemical agents are selected according to different varieties and different periods of citrus. For example: during the fruit expansion period of Wogan oranges, the nitrogen, phosphorus and potassium compound fertilizer solution needs to be filled into the medicine box 5. During the flowering preservation period of Satsuma mandarins, the mixed solution of boron fertilizer and gibberellin needs to be filled into the medicine box 5. In addition, different insecticides need to be prepared according to different pests. This embodiment will not elaborate too much. And due to the design of a plurality of ventilation holes provided at the upper end of the medicine box 5, it cannot be filled up when filling the chemical agent to prevent the chemical agent from spilling out during the movement of the device, thus causing waste of the chemical agent;

[0058] A2. Ratio parameter adjustment: Since the medicaments are in high concentration during filling and different medicaments have different ratios with water, it is necessary to adjust the opening angle of valve 7 to adjust the ratio of different medicaments to water, preventing the citrus from being poisoned by overly concentrated medicaments and also preventing the irrigation effect from being reduced due to overly diluted medicaments.

[0059] A3. Water source preparation: Since farmers may use relatively cheap well water or river water to reduce the usage cost when irrigating farmland, and there are a large number of impurities in well water and river water, it is necessary to filter the water first when filling water into water tank 2 to prevent impurities from clogging the water pump 3, pipelines or nozzles, thus affecting the normal operation of the device.

[0060] S2. Irrigation stage:

[0061] B1. Device positioning and startup: Move the device to the position where irrigation is required. Since the crawler base 1 is designed with crawlers, it does not need to be fixed. Then move according to the citrus to be irrigated and start the water pump 3.

[0062] B2. Automatic air discharge: When water flows through the guiding groove 44, the inner wall deflector 442 guides the water flow to rotate, and the air with relatively low density floats to the top through the through holes 443 and is discharged. At the same time, due to the design of multiple protrusions 441, it can also increase the friction between the water flow and the guiding groove 44, reducing the turbulence and vortex of the water flow.

[0063] B3. Active mixing: When water flows through, use the pressure difference between the mixing pipe 42 and the feed pipe 43 to draw the medicament in the medicine tank 5 into the mixing pipe 42. At the same time, since the greater the water flow rate in the mixing pipe 42, the greater the pressure difference between the mixing pipe 42 and the feed pipe 43, the device can automatically adjust the ratio of the medicament to water according to the size of the water flow during use to ensure that the ratio of the medicament to water is always consistent, and there will be no situation of less water and more medicine or more water and less medicine, increasing the stability of the device during use.

[0064] S3. End and maintenance stage:

[0065] C1. Shutdown operation: After the citrus irrigation is completed, turn off the water pump 3, but do not turn off the nozzle, and let the water in the pipeline flow out automatically under the action of gravity to prevent the medicament from spilling randomly during the long process of device movement.

[0066] C2. Pipeline cleaning: Extract the remaining medicament in the medicine tank 5, then fill the medicine tank 5 with clean water, start the water pump 3 again, and use the flow of clean water to dilute and carry out the residual medicament on the inner wall of the pipeline, preventing the newly added medicament from reacting with the residual medicament when the device is used next time, thus affecting the usage effect of the medicament.

[0067] C3. Daily maintenance: After each use, it is necessary to check whether the connecting pipe 6, the valve 7 and the through hole 443 are blocked. If blocked, clean them in time. At the same time, it is also necessary to check the sealing performance of the check valve 8, lubricate the valve 7 weekly, and clean and disinfect the inside of the medicine box 5.

[0068] It should be noted that the specific installation methods, circuit connection methods and control methods of the crawler base 1, the water pump 3, the valve 7 and the check valve 8 in the present invention are all conventional designs, and the present invention will not elaborate in detail.
