[0002] Fertilizer sprinkler irrigation is an agricultural irrigation and fertilization method that combines fertilization with sprinkler irrigation technology. It has advantages such as high efficiency, precision, water and fertilizer saving. The fertilizer solution is evenly sprayed onto the root zone or leaves of crops through the sprinkler irrigation system, realizing the simultaneous irrigation and fertilization.

[0003] Chinese Patent No. CN202221678340.6 discloses an integrated fertilization and irrigation device for snow pea cultivation, comprising a base plate, a mixing tank at the top of the base plate, a water pump at the top of one side of the base plate near the mixing tank, a first electric telescopic rod at the top of the base plate, a lifting plate at the top of the first electric telescopic rod, a fixed seat at the top of the lifting plate, second electric telescopic rods on both sides of the fixed seat, a movable spraying seat at the other end of the second electric telescopic rod, a spraying pipe inside the movable spraying seat, and a plurality of spray heads arranged in a linear array connected to one side of the spraying pipe.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figures 1-6 As shown, an integrated fertilization and irrigation device for growing snow peas includes a main body 1. Adjustable spraying devices 2 and automatic feeding devices 3 are arranged on both sides of the main body 1. The adjustable spraying device 2 includes a support frame 21. A water tank 24 is fixedly installed on the top of the support frame 21. An input pipe 22 is fixedly installed on the bottom of the water tank 24. A second pump 23 is fixedly installed at the other end of the input pipe 22. A conveying pipe 25 is fixedly installed on one side of the second pump 23. A pressure gauge 26 is installed through and fixedly installed on one side of the conveying pipe 25. Two limit buckles 27 are installed through and fixedly installed on one side of the conveying pipe 25. The support frame 21 is fixedly installed on the other side of the two limit buckles 27. A servo motor 33 is fixedly installed on the top of the support frame 21. A second gear 32 is fixedly installed at the output end of the servo motor 33.

[0030] During operation, the second pump 23 draws fertilizer mixture from the water tank 24 through the input pipe 22 and delivers it to the nozzle 38 through the delivery pipe 25. The pressure gauge 26 monitors the delivery pressure in real time to ensure stable spray pressure and avoid damage to crops due to excessive pressure or impact on the irrigation range due to excessively low pressure.

[0031] Furthermore, the adjusting spray device 2 also includes a first gear 31, which meshes with a second gear 32. A movable sleeve 29 is installed through and fixedly mounted on one side of the first gear 31. The movable sleeve 29 is sleeved on the outside of the fixed sleeve 28 and can rotate. A delivery pipe 25 is fixedly mounted on the bottom of the fixed sleeve 28. A spray pipe 36 is fixedly mounted on the top of the movable sleeve 29. A nozzle 38 is fixedly mounted on the other end of the spray pipe 36.

[0032] During operation, the servo motor 33 drives the second gear 32 to rotate, which in turn drives the movable sleeve 29 to rotate on the fixed sleeve 28 through the meshing first gear 31, thereby enabling the nozzle 38 to rotate horizontally and cover different areas of the snow pea planting row.

[0033] Furthermore, the adjusting spray device 2 also includes a first electric push cylinder 34, which is hinged to the top of the movable sleeve 29. A first push rod 35 is movably installed on the inner wall of the first electric push cylinder 34. The other end of the first push rod 35 is hinged to the spray pipe 36. A spring 37 is fixedly installed around the spray pipe 36.

[0034] During operation, the first electric push cylinder 34 pushes the first push rod 35, causing the spray pipe 36 to pitch around the hinge point, thereby achieving vertical pitch adjustment of the nozzle 38. The spring 37 provides buffering to prevent the spray pipe 36 from shaking violently during the adjustment process, ensuring accurate spray angle.

[0035] Furthermore, the automatic feeding device 3 includes a base 41, a second electric push cylinder 42 is hinged to the top of the base 41, a second push rod 43 is movably installed at the output end of the second electric push cylinder 42, and a storage bin 44 is hinged to one end of the second push rod 43.

[0036] During operation, the second electric push cylinder 42 drives the second push rod 43, causing the storage bin 44 to tilt around the bearing 45. The tilt angle is controlled by the stroke of the second electric push cylinder 42, which facilitates the smooth sliding of fertilizer.

[0037] Furthermore, the automatic feeding device 3 also includes two bearings 45, which are fixedly installed on the top of the base 41, and the two bearings 45 are installed through and rotatably on both sides of the storage bin 44.

[0038] During operation, the bearing 45 supports the rotation of the storage bin 44, reducing frictional resistance and ensuring a smooth tilting process of the storage bin 44, thus preventing fertilizer from accumulating and getting stuck.

[0039] Furthermore, a flow control valve 48 is fixedly installed on one side of the storage bin 44, a conveying channel 46 is opened on one side of the storage bin 44, a turbine flow meter 49 is fixedly installed on the conveying channel 46, the flow control valve 48 is electrically connected to the turbine flow meter 49, and a drop bucket 47 is fixedly installed on one side of the conveying channel 46.

[0040] During operation, the fertilizer in the storage bin 44 flows down to the hopper 47 along the conveying channel 46 under its own weight and the tilting action of the storage bin 44. The turbine flow meter 49 monitors the fertilizer flow rate through the conveying channel 46 in real time and transmits the flow signal to the flow control valve 48. The flow control valve 48 automatically adjusts its opening according to the preset fertilizer application requirements to precisely control the fertilizer delivery rate, ensuring that the amount of fertilizer entering the hopper 47 meets the needs of the snow peas at the current growth stage, and avoiding excessive or insufficient fertilizer from affecting crop growth.

[0041] Furthermore, the main body 1 includes a mixing chamber 11, a drop trough 12 is provided on the top of the mixing chamber 11, a stepper motor 13 is fixedly installed on the top of the mixing chamber 11, and a stirring blade is fixedly installed on the output end of the stepper motor 13, which is located in the inner cavity of the mixing chamber 11; a solenoid valve 14 is fixedly installed on one side of the mixing chamber 11, and the other side of the solenoid valve 14 is connected to an inlet pipe 15, which is fixedly installed at the output end of the first pump 16;

[0042] During operation, fertilizer is placed into the mixing chamber 11 through the drop trough 12. The stepper motor 13 drives the mixing blades to rotate, mixing the fertilizer and water evenly. After the solenoid valve 14 is opened, the first pump 16 draws the mixture into the inlet pipe 15. The concentration of the mixture can be adjusted by controlling the amount of fertilizer and water to meet the nutritional needs of different growth stages of snow peas.

[0043] Furthermore, a connecting pipe 17 is fixedly installed at the output end of the first pump 16, and a water tank 24 is fixedly installed at the other end of the connecting pipe 17. An inlet valve 18 is fixedly installed through and on one side of the mixing chamber 11. The inlet valve 18 is connected to an external water source and is used to control the amount of water entering the water tank 24. The flow control valve 48 is linked with the inlet valve 18, and the dynamic ratio of fertilizer and water is achieved by adjusting the opening ratio of the two.

[0044] During operation, the inlet valve 18 is opened, and external water enters the mixing chamber 11 through the inlet valve 18 to provide water for water-fertilizer mixing. The flow control valve 48 and the inlet valve 18 form a linkage mechanism. When the flow control valve 48 adjusts the fertilizer delivery amount, the inlet valve 18 will adjust the water inlet amount synchronously according to the preset ratio between the two to ensure that the ratio of fertilizer to water is always adapted to the nutritional needs of the snow peas at different growth stages. The stepper motor 13 drives the mixing blade to rotate at high speed, which fully mixes the fertilizer and water entering the mixing chamber 11 to form a uniform water-fertilizer mixture. After the mixing is completed, the solenoid valve 14 is opened, and the first pump 16 draws the mixture in the mixing chamber 11 through the inlet pipe 15 and transports it to the water tank 24 for storage through the connecting pipe 17, providing a stable source of water and fertilizer for subsequent sprinkler irrigation.

[0045] Working principle: Step 1, fertilizer is put into mixing chamber 11 through drop trough 12. Stepper motor 13 drives mixing blade to rotate, mix fertilizer and water evenly. Solenoid valve 14 is opened, and first pump 16 draws in the mixture through inlet pipe 15 and delivers it to water tank 24 for storage through connecting pipe 17.

[0046] Step two: The second pump 23 draws the mixture from the water tank 24 through the input pipe 22 and delivers it to the nozzle 38 through the delivery pipe 25. The pressure gauge 26 monitors the delivery pressure in real time to ensure stable spraying. The servo motor 33 drives the second gear 32 to rotate, which meshes with the first gear 31 to drive the movable sleeve 29 to rotate on the fixed sleeve 28, adjusting the horizontal angle of the nozzle 38. The first electric push cylinder 34 pushes the first push rod 35, causing the spray pipe 36 to pitch. The spring 37 provides cushioning, achieving precise adjustment of the vertical angle to cover different planting areas.

[0047] Step 3: The automatic feeding device 3 works in concert to complete precise feeding: the second electric push cylinder 42 drives the second push rod 43 to extend and retract, causing the storage bin 44 to rotate around the bearing 45 and adjust the tilt angle, so that the fertilizer in the storage bin 44 can smoothly enter the conveying channel 46; the turbine flow meter 49 detects the flow speed and total amount of fertilizer in the conveying channel 46 in real time and feeds the data back to the flow control valve 48. The flow control valve 48 automatically adjusts the channel opening according to the amount of fertilizer required for the growth of snow peas, and precisely controls the amount of fertilizer delivered; at the same time, the water inlet valve 18 adjusts the water inlet according to the opening signal of the flow control valve 48 according to the preset ratio, so as to ensure that the fertilizer and water ratio entering the mixing chamber 11 is appropriate. Finally, through the mixing treatment of the mixing chamber 11, a water-fertilizer mixture with a precise concentration is provided for sprinkler irrigation, realizing the efficient coordination of fertilization and sprinkler irrigation.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
