DETAILED DESCRIPTION

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] like Figure 1-Figure 6 As shown, this embodiment proposes a uniformly mixed water and fertilizer sprinkler irrigation equipment, including a body 1, the body 1 is connected to an electric telescopic leg, the bottom end of the electric telescopic leg is rotatably connected to a walking wheel 24, the electric telescopic leg can adopt a conventional structure, for example, the electric push rod can be used to push the leg to move, thereby realizing the telescopic function, and then realizing the adjustment of the height of the body 1.

[0036] The vehicle body 1 is connected with a connecting frame, and the device can be connected to equipment such as a tractor through the connecting frame, so as to realize the walking work of the entire vehicle body 1.

[0037] The vehicle body 1 is connected to a plurality of upper spray pipes 9, and the vehicle body 1 is also connected to a plurality of vertically arranged lower spray pipes 3. The fertilization methods include root soil fertilization and foliar fertilization. The lower spray pipes 3 can realize root soil fertilization, and the upper spray pipes 9 can realize foliar fertilization. Foliar fertilization, as a fertilization measure for strengthening crop nutrition and preventing certain nutrient deficiency symptoms, has been rapidly promoted and applied. Practice has proved that foliar fertilization is one of the fertilization technologies with rapid fertilizer effect, high fertilizer utilization rate and low fertilizer dosage.

[0038] The upper spray pipe 9 is rotatably connected to a rotating rod 19, and a spray head 20 is slidably sleeved outside the rotating rod 19. The spray head 20 includes a nozzle, which is arranged at the lower end of the spray head 20 for spraying water and fertilizer. The upper spray pipe 9 is provided with a reducing groove 22, and the spray head 20 is connected to a sliding shaft 21, which is slidably arranged in the reducing groove 22. When the spray head 20 rotates in a direction perpendicular to the ground, the distance between the rotating rod 19 and the nozzle becomes larger.

[0039] With the rotation point of the rotating rod 19 as the center point, the reducing groove 22 is approximately elliptical in shape rather than a conventional circle. The reducing groove 22 is set to guide the rotation of the nozzle 20. Since the nozzle 20 is slidably mounted on the rotating rod 19, when the rotating rod 19 rotates, the nozzle 20 can be driven to rotate at the same time. Because the reducing groove 22 is a reducing groove, when the nozzle 20 rotates, relative sliding between the nozzle 20 and the rotating rod 19 can be achieved, thereby adjusting the distance between the rotating rod 19 and the nozzle, and adjusting the spraying range.

[0040] The vehicle body 1 is fixedly connected with a rotating shaft 17, and the rotating shaft 17 is rotatably connected with a large gear 14. A rotating rod 19 is fixedly sleeved with a passive gear 18. The large gear 14 and the passive gear 18 are meshed with each other. When the large gear 14 rotates, the passive gear 18 can be driven to rotate, thereby driving the rotating rod 19 to rotate. The large gear 14 is connected to the upper nozzle 9 through a torsion spring 30. The elastic force of the torsion spring 30 can rotate the nozzle 20 into an inclined state.

[0041] The rotating shaft 17 is rotatably connected to a pinion 15, and the vehicle body 1 is slidably connected to a slide bar 13 that moves in the vertical direction. A rack is fixedly connected to one side of the slide bar 13, and the rack and the pinion 15 are meshed. The slide bar 13 can only slide in the vertical direction. When the slide bar 13 moves, it can drive the pinion 15 to rotate, and the pinion 15 can only rotate around the rotating shaft 17.

[0042] The large gear 14 is provided with a plurality of slots 29, and the small gear 15 is slidably connected with an insertion rod 16 that can slide into the slot 29. The insertion rod 16 is connected to the small gear 15 through a tension spring 27. One end of the tension spring 27 is connected to the insertion rod 16, and the other end is connected to the small gear 15. The number of slots 29 is set to be sufficient to facilitate the sliding of the insertion rod 16.

[0043] In the initial state, under the elastic force of the tension spring 27, the insertion rod 16 can slide into the slot 29. At this time, when the small gear 15 rotates, the large gear 14 can be driven to rotate through the insertion rod 16, thereby adjusting the angle of the nozzle 20 and deforming the torsion spring 30. When the nozzle 20 is blocked, the insertion rod 16 will slide out of the slot 29. At this time, the torsion spring 30 will drive the large gear 14 to reset, thereby driving the nozzle 20 to rotate to an inclined angle, so that the adjacent nozzle 20 sprays the position of the blocked nozzle 20, so that the spraying efficiency is not affected by the blockage, and the spraying efficiency and quality are effectively improved.

[0044] The vehicle body 1 is connected to an electric push rod 10, which includes a push rod. The sliding direction of the push rod is parallel to the ground. The push rod is provided with a plurality of inclined grooves 12. One end of a slide rod 13 is slidably arranged in the inclined groove 12. When the electric push rod 10 moves, the inclined groove 12 can be driven to move, and the inclined groove 12 can drive the slide rod 13 to rise.

[0045] The slide bar 13 can drive the small gear 15 to rotate, the small gear 15 can drive the large gear 14 to rotate, the large gear 14 can drive the rotating rod 17 to rotate, and the rotating rod 17 can drive the nozzle 20 to rotate, so that when the electric push rod 10 moves, it can drive several nozzles 20 to rotate at the same time, without complex control, simple operation, and reasonable overall structure.

[0046] The upper nozzle 9 is slidably connected with a push rod 25, which is connected to the upper nozzle 9 through a compression spring 11. The push rod 25 is arranged on one side of the insertion rod 16. The upper end of the compression spring 11 is connected to the upper nozzle 9, and the lower end is connected to the push rod 25. One side of the push rod 25 is provided with teeth.

[0047] The vehicle body 1 is rotatably connected to a plurality of transmission shafts, which are arranged between two upper nozzles 9. A water wheel gear 31 is rotatably connected inside the upper nozzle 9. The teeth of the water wheel gear 31 and the top rod 25 are meshed with each other. One end of the transmission shaft is fixedly connected to the water wheel gear 31, and the other end is fixedly connected to the water wheel 23. The water wheel 23 is arranged in an adjacent nozzle 20.

[0048] When water flows through the nozzle 20, the water wheel 23 drives the water wheel gear 31 to rotate, and the water wheel gear 31 drives the push rod 25 to rise, compressing the compression spring 11. At this time, the tension spring 27 can drive the insertion rod 16 to slide into the slot 29. When the nozzle 20 is blocked, the corresponding water wheel 23 no longer rotates. When the compression spring 11 drives the push rod 25 to descend, the push rod 25 can drive the insertion rod 16 to move out of the slot 29, so that the nozzle 20 is reset, and the adjacent nozzles 20 spray the position of the blocked nozzle 20, so as not to affect the efficiency and quality of spraying due to blockage.

[0049] The elastic force of the compression spring 11 is greater than that of the tension spring 27 , so that when the push rod 25 descends, the insertion rod 16 can be driven to move out of the slot 29 .

[0050] The vehicle body 1 is fixedly connected with a plurality of infrared receivers 28 and a plurality of infrared transmitters matched with the infrared receivers 28. The electric telescopic legs, the infrared transmitters, the infrared receivers 28 and the electric push rod 10 are connected with a controller. The infrared receivers 28 can receive the signals emitted by the infrared transmitters. When the infrared receivers 28 cannot receive the infrared signals, it indicates that crops are detected at this time, and the corresponding signals are transmitted to the controller, and the controller can judge the height of the crops.

[0051] When the crops are high, the sprinkler head 20 rotates in a direction perpendicular to the ground. At this time, the distance between the rotating rod 17 and the nozzle becomes larger, and the electric telescopic legs are extended, so as to keep the spraying range unchanged and adapt to higher crops. The spraying range can be adaptively adjusted according to the height of the crops in the farmland, so that the spraying range can be adapted to the situation of the crops, which is conducive to better sprinkler irrigation work in the farmland.

[0052] The vehicle body 1 is fixedly connected with a mixing barrel 4 and a fertilizer barrel 2, the mixing barrel 4 is connected with a water supply pipe 5 and the fertilizer barrel 2, the vehicle body 1 is connected with a water spray pipe 7, the water spray pipe 7 is connected with the lower spray pipe 3 through a connecting pipe and a corresponding nozzle 20, and also includes a spray pump 26 for transporting water in the mixing barrel 4 to the water spray pipe 7, one end of the spray pump 26 is connected with the water spray pipe 7, and the other end is connected with the discharge port of the mixing barrel 4, and a pressure pump can also be provided to increase the pressure for easy spraying.

[0053] The length of the water supply pipe 5 is long enough, and the water tank can be set on agricultural equipment such as a tractor. Water is supplied to the mixing barrel 4 through the water supply pipe 5, and fertilizer is supplied to the mixing barrel 4 through the fertilizer barrel 2. The water supply pipe 5 and the fertilizer barrel 2 are both provided with solenoid valves, and the solenoid valves are connected to the controller. By controlling the opening time of the solenoid valve, the corresponding ratio of water and fertilizer can be controlled, thereby better achieving the mixing of water and fertilizer.

[0054] A motor is fixedly connected to the outer wall of the mixing barrel 4, and a mixing shaft 6 is rotatably connected inside the mixing barrel 4. One end of the mixing shaft 6 passes through the mixing barrel 4 and is connected to the motor. The mixing shaft 6 is rotatably connected to a plurality of spoiler rods 8, and the spoiler rods 8 are fixedly connected to walking wheels 24, which can move along the inner wall of the mixing barrel 4.

[0055] The motor can drive the stirring shaft 6 to rotate, and the stirring shaft 6 can drive the walking wheel 24 to make a circular motion. When the walking wheel 24 moves, it can drive the spoiler rod 8 to rotate around the stirring shaft 6, thereby better facilitating the mixing work of the stirring barrel 4, and realizing uniform mixing of water and fertilizer, thereby facilitating the subsequent irrigation work.

[0056] The method of use includes the following steps:

[0057] S1: The spray pump 26 pumps the water in the mixing barrel 4 into the water spray pipe 7, and then sprays it out through the spray head 20. The water flow drives the water wheel 23 to rotate, and the water wheel 23 drives the water wheel gear 31 to rotate. The water wheel gear 31 drives the top rod 25 to rise, so that the compression spring 11 is compressed, and the tension spring 27 drives the insertion rod 16 to slide into the slot 29, so that the torsion spring 30 is deformed;

[0058] S2: The controller controls the infrared transmitter to work. When the infrared receiver 28 cannot receive the infrared signal, it indicates that the crop is detected at this time, and transmits the corresponding signal to the controller. The controller controls the electric push rod 10 and the electric telescopic legs to work. The electric telescopic legs adjust the height of the vehicle body 1, and the electric push rod 10 drives the push rod to move;

[0059] S3: The push rod drives the inclined slot 12 to move, the inclined slot 12 drives the slide bar 13 to move in the vertical direction, the slide bar 13 drives the small gear 15 to rotate, the small gear 15 drives the large gear 14 to rotate, the large gear 14 drives the rotating rod 17 to rotate, the rotating rod 17 drives the nozzle 20 to rotate, and at the same time, the sliding shaft 21 slides in the variable diameter groove 22 to achieve relative sliding between the nozzle 20 and the rotating rod 17, and realize the simultaneous movement of multiple nozzles 20;

[0060] S4: When one of the nozzles 20 is clogged, the water wheel 23 stops rotating, the tension spring 11 drives the push rod 25 to descend, and the push rod 25 drives the insertion rod 16 to move out of the slot 29. At this time, the torsion spring 30 drives the large gear 14 to reset, and the large gear 14 drives the rotating rod 17 to rotate, so that the distance between the rotating rod 17 and the nozzle is reduced, and the spraying range of the adjacent nozzle 20 is increased, and the adjacent nozzle 20 sprays the position of the clogged nozzle 20.
