Description

Technical Field

[0001] This utility model relates to the field of farmland irrigation technology, specifically to an integrated water, fertilizer and pesticide device. Background Technology

[0002] Strict and meticulous management of water, fertilizer, and pesticides is required throughout the growth process of crops. The needs of crops for water, fertilizer, and pesticides vary at different stages of seedling cultivation and growth. To ensure the normal growth and development of crops, water, fertilizer, and pesticides must be supplied regularly and in measured quantities according to the specific needs of crops at each growth stage.

[0003] Current agricultural irrigation methods include drip irrigation, furrow irrigation, and sprinkler irrigation. These methods typically involve irrigation after manual fertilization. Drip irrigation, however, only mixes fertilizer with water before application, allowing the water to dissolve the fertilizer and facilitate its absorption by the roots. Manual fertilization is prone to errors and cannot achieve precise application. Furthermore, pesticides cannot be sprayed simultaneously with irrigation. Therefore, current agricultural irrigation methods mostly involve separate application of water, fertilizer, and pesticides, resulting in low efficiency, time-consuming, labor-intensive processes, and significant workload, which require improvement.

[0004] With the continuous development of agricultural technology, integrated water and fertilizer equipment is emerging, but the investment is too high and it is inconvenient to popularize. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an integrated water, fertilizer and pesticide device with simple structure, low cost and convenient implementation. It successfully realizes the integrated irrigation of water, fertilizer and pesticide, and achieves precise fertilization and pesticide application. It is widely used in precision agricultural irrigation.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model includes a water pump, a fertilizer and pesticide mixing unit, and a spraying unit installed in the farmland. The farmland is connected to the water pump through an outlet pipe, the spraying unit is connected to the outlet pipe of the water pump, and the inlet pipe of the water pump is connected to a water source.

[0008] A further improvement of this utility model is that the fertilizer and pesticide mixing unit is a solution mixing tank, and the top of the solution mixing tank is provided with an opening.

[0009] A further improvement of this utility model is that the solution mixing tank is connected to the water outlet pipe through the liquid inlet pipe at the bottom, and the liquid inlet pipe is provided with a water return pipe connected to the water inlet pipe.

[0010] A further improvement of this utility model is that: the inlet pipe is provided with an inlet valve, which is located at the connection between the inlet pipe and the outlet pipe; the return pipe is provided with a return valve, which is located at the connection between the return pipe and the inlet pipe.

[0011] A further improvement of this utility model is that: both the inlet valve and the return valve are electrically controlled valves; a water level sensor is provided inside the solution mixing tank; the water level sensor is electrically connected to the input terminal of the controller; and the output terminal of the controller is connected to the inlet valve and the return valve respectively.

[0012] A further improvement of this utility model is that the spraying unit includes spray pipes evenly distributed in the farmland and spraying units evenly distributed on the spray pipes and connected to the spray pipes, and the spray pipes are connected through connecting pipes and water outlet pipes.

[0013] A further improvement of this utility model is that the spraying unit is a nozzle.

[0014] A further improvement of this utility model is that the spraying unit is a spray gun, and the spray gun is connected to the spray pipe through a branch pipe.

[0015] A further improvement of this utility model is that the branch pipe is connected to the nozzle via a tee connector.

[0016] A further improvement of this utility model is that a support rod connected to the ground is provided at the connection between the branch pipe and the spray gun.

[0017] The beneficial effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0018] This utility model features a simple structure, low cost, and ease of implementation. Based on sprinkler irrigation, this device adds a fertilizer and pesticide mixing unit, successfully realizing a modern agricultural technology of integrated water, fertilizer, and pesticide irrigation. It mixes soluble liquid pesticides and solid fertilizers into a solution, which is then used with irrigation water to supply water, fertilizer, and pesticides to crops. This not only eliminates the need for manual fertilization and spraying, greatly improving work efficiency, but also achieves scientific and precise fertilization, resulting in rapid fertilizer effect, high nutrient utilization, and environmental benefits. It effectively avoids the problems of volatilization loss, slow dissolution, and ultimately slow fertilizer effect caused by applying fertilizer to relatively dry topsoil.

[0019] This integrated water, fertilizer, and pesticide irrigation technology allows for the quantitative control of pesticide and fertilizer application, ensuring crops receive adequate nutrition at each stage of growth and development. It eliminates deficiencies in pesticides and nutrients while avoiding excessive application, thus achieving both high yields and high-quality crops. Its widespread adoption is warranted.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] An integrated water, fertilizer, and pesticide device, such as Figure 1-3 As shown, the device includes a water pump 1, a fertilizer and pesticide mixing unit, and a spraying unit installed in farmland 10. Farmland 10 is connected to water pump 1 via an outlet pipe 8, and the spraying unit is connected to the outlet pipe 8 of water pump 1. The inlet pipe 2 of water pump 1 is connected to a water source. The water pump 1 has a head of over 20 meters, with an optimal head of 32 meters, and a pressure of up to 3.2 atmospheres. The fertilizer and pesticide mixing unit and the spraying unit in farmland 10 can operate smoothly with a pressure of 2 atmospheres. Therefore, this device does not require a separate booster pump to meet the spraying needs of the spraying unit and the mixing needs of the fertilizer and pesticide mixing unit. In this way, water pump 1 delivers water from the water source through the inlet pipe 2 to the fertilizer and pesticide mixing unit and the spraying unit in farmland 10 via the outlet pipe 8. This successfully completes the irrigation of water, fertilizer, and pesticides, meeting the water, fertilizer, and pesticide needs of crops at each growth stage and ensuring a double harvest of crop yield and quality.

[0026] like Figure 1 As shown, the fertilizer and pesticide mixing unit is a solution mixing tank 5. The top of the solution mixing tank 5 is provided with an opening 5-1, through which a certain amount of fertilizer or pesticide can be added to the solution mixing tank 5 as needed.

[0027] The solution mixing tank 5 is connected to the outlet pipe 8 via an inlet pipe 7 at the bottom. The inlet pipe 7 is equipped with a return pipe 3 connected to the inlet pipe 2. An inlet valve 6 is installed on the inlet pipe 7 at the connection between the inlet pipe 7 and the outlet pipe 8. Water from the outlet pipe 8 is fed into the solution mixing tank 5 through the inlet pipe 7 to dissolve the pesticides and / or fertilizers added to the solution mixing tank 5. Once the water level reaches a set value, the inlet valve 6 is closed to stop the injection of water into the solution mixing tank 5.

[0028] A return water valve 4 is installed on the return water pipe 3, and the return water valve 4 is located at the connection between the return water pipe 3 and the inlet pipe 7. After closing the inlet valve 6, the return water valve 4 is opened to allow the prepared pesticide solution, fertilizer solution, or fertilizer-pesticide solution in the solution mixing tank 5 to be sent into the inlet pipe 2 through the return water pipe 3. Under the action of the water pump 1, the water from the water source, together with the solution in the solution mixing tank 5, is sent into the spraying unit through the outlet pipe 8, spraying the farmland 10 like rain, meeting the water, fertilizer, and pesticide requirements of the crops in the farmland 10 at each growth stage, and ensuring the healthy growth of the crops.

[0029] like Figure 3 As shown, both the inlet valve 6 and the return valve 4 are electrically controlled valves. The fertilizer and pesticide mixing unit has intelligent control capabilities. The solution mixing tank 5 is equipped with a water level sensor 17 electrically connected to the input of the controller 18. The output of the controller 18 is connected to both the inlet valve 6 and the return valve 4. The water level sensor 17 can detect the water level in the solution mixing tank 5 in real time and transmit the detected water level information to the controller 18. The controller 18 is a PLC control unit with intelligent control capabilities. The controller 18 can analyze, judge, and compare the real-time water level information transmitted by the water level sensor 17.

[0030] When water needs to be added to the solution mixing tank 5, the controller 18 commands the inlet valve 6 to open, and water from the outlet pipe 8 is continuously fed into the solution mixing tank 5 to dissolve the fertilizer and pesticides inside. When the water level in the solution mixing tank 5 reaches the set height, the controller 18 commands the inlet valve 6 to close and the return valve 4 to open. The solution in the solution mixing tank 5 is then sent to the inlet pipe 2 through the return pipe 3, and together with the water source, it is sent to the spraying unit by the water pump 1. When all the solution in the solution mixing tank 5 has flowed out, the controller 18 commands the return valve 4 to close, stopping the injection of solution into the inlet pipe 2.

[0031] The amount of fertilizer and / or pesticide added to the solution mixing tank 5, as well as the amount of water added to the solution mixing tank 5, can be set according to the needs of the crops. This achieves the requirements of precise fertilization and pesticide application, completely solving the environmental pollution caused by excessive fertilization and pesticide application. Moreover, the entire process of preparing and spraying pesticides does not require manual intervention, resulting in high work efficiency.

[0032] In summary, this device can be used alone for sprinkler irrigation when crops are short of water during their growth process; it can achieve integrated water and fertilizer irrigation when crops are short of both water and fertilizer; and it can also achieve integrated water, fertilizer, and pesticide irrigation when crops are short of water, fertilizer, and pesticides. Therefore, the implementation and promotion of this utility model are of great significance.

[0033] like Figure 1As shown, a spraying unit is installed in the farmland 10, and the spraying unit is connected to the outlet pipe 8 of the water pump 1. The spraying unit includes spray pipes 12 evenly distributed within the farmland 10 and spray units evenly distributed on and connected to the spray pipes 12. The spray pipes 12 are connected to the outlet pipe 8 via connecting pipes 9. Under the action of the water pump 1, water from the water source is sequentially delivered into the farmland 10 through the outlet pipe 8, connecting pipe 9, spray pipes 12, and spray units to irrigate the crops and meet their water and nutrient needs at various growth stages. The spray unit is a nozzle 11, through which water in the spray pipes 12 is sprayed into the farmland 10.

[0034] like Figure 3 As shown, the spraying unit is a spray gun 16, which is connected to the spray pipe 12 via a branch pipe 15. For ease of use, the height of the spray gun 16 can be adjusted according to the height of the crops. Water from the spray pipe 12 is sent into the spray gun 16 via the branch pipe 15, and then sprayed onto the farmland 10 by the spray gun 16.

[0035] The branch pipe 15 is connected to the spray pipe 12 via a tee connector 13, and a support rod 14 connected to the ground is provided at the connection between the branch pipe 15 and the spray gun 16. The support rod 14 makes the spray gun 16 more secure and reliable.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are by no means intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description; it is impossible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the protection scope of this invention.
