Description

Technical Field

[0001] The invention relates to the field of agricultural sprinkler irrigation, and in particular to a continuous water supply sprinkler irrigation system and a sprinkler irrigation method. Background Art

[0002] Sprinkler irrigation is an irrigation method that uses a water pump and pipe system or the drop of a natural water source to spray water into the air and disperse it into small droplets or form mist droplets that fall on plants and the ground. Sprinkler irrigation includes fixed sprinkler irrigation, semi-fixed sprinkler irrigation and mobile sprinkler irrigation, which has the characteristics of saving water, not destroying soil structure and strong adaptability.

[0003] Mobile sprinkler irrigation is the current development trend of agricultural sprinkler irrigation, and mobile sprinklers are increasingly used in large fields. The water supply methods for large-scale mobile sprinkler irrigation include pipeline water supply and ditch water supply. Large-scale mobile sprinklers mainly include reel-type sprinklers and horizontal mobile sprinklers. Among them, the reel-type sprinkler consists of a reel car and a sprinkler car. The reel car carries the coil and provides water pressure. The front end of the coil is connected to the sprinkler car, and the rear end is connected to the water source. The sprinkler car is pulled by a tractor to pull the pipe to spray water. The moving distance of the sprinkler car is limited by the length of the coil. It is necessary to constantly transfer and change the water connection point to complete all irrigation. The process of placing the pipe and transferring the field requires tractor traction. To this end, the publication number CN109042252A adds power to the sprinkler vehicle and designs a water storage capacity change device for the sprinkler vehicle water tank, so that the sprinkler vehicle can add water and increase weight when moving forward so that it has enough grip to pull the pipe, realize self-propelled water spraying operation, and release water to reduce weight when rewinding to reduce pipe retraction resistance, thereby solving the problem of relying on external power to release the pipe, but still cannot solve the inconvenience caused by the need to carry a huge pipe tray during operation and the limitation of pipe length. Large-scale horizontal mobile sprinkler is even more of a huge machine, with a truss of hundreds of meters or even thousands of meters, and it is usually supplied with water by ditches. This type of sprinkler operates on large areas of flat land, especially on regular long plots with high irrigation efficiency, but is not suitable for small plots. The patent application with publication number CN108207581A discloses a lightweight and simplified intelligent self-propelled translational cantilever sprinkler, which is equipped with a water suction component on the walking frame and completes the sprinkler operation by sucking water from the channel. This invention solves the problem of the inflexibility of large sprinkler machines, but requires increasing the channel distribution density, which will lead to reduced land utilization and increased channel construction costs.

Specifically, the water trough 2 includes a retractable trough frame 6, a trough liner 7, a trough wheel 8, a tightening line 9 and a wire wheel 10. The left and right sides of the trough frame 6 are respectively formed by a plurality of X-shaped metal components that can be movably connected. The X-shaped metal components on the left and right sides are connected by a plurality of cross bars. The trough liner 7 is placed in the trough frame 6 to form a water storage space.

[0046] In the present invention, two pairs of wheels 101 are provided on the left and right sides of the bottom of the frame 1 of the mobile sprinkler; the outer wheel tracks of the groove wheels 8 on both sides of the water trough are smaller than the inner wheel tracks of the wheels 101 on both sides of the sprinkler, the water supply pipe 3 and the water outlet pile 4 are located between the groove wheels 8 and the wheels 101 on the same side, and the distance between the outer side of the groove wheels 8 on the side of the water supply pipe 3 and the wheels 101 of the mobile sprinkler leaves enough space for arranging the water supply pipe 3, the water outlet pile 4 and the guide rod 36, the height of the mobile water trough 2 is also smaller than the height below the sprinkler frame 1, the water outlet of the water outlet pile 4 extends above the water trough 2, and the top of the water outlet pile 4 is located below the frame 1, so that the sprinkler can pass through without hindrance.

[0047] Embodiment 1:

[0048] In this embodiment, if Figures 2 to 4 As shown, the water supply pipe 3 is laid on the ground surface, and the water outlet pile 4 is provided with a first solenoid valve 13 for controlling the water outlet. The first solenoid valve 13 is a self-holding solenoid valve, and the first solenoid valve 13 leads to wiring A13a and wiring B13b; the outer side of the wall of the water tank 2 is provided with wires A12a and wires B12b, and the two wires are connected from the positive and negative poles of the power supply equipment in the power assembly 17. The two wires are respectively provided with two electrical contacts at the front end and the rear end of the water tank 2, and the two wirings of the first solenoid valve 13 are also provided with two electrical contacts.

[0049] When the water tank 2 approaches the water outlet pile 4, the electrical contacts connecting the wiring A13a and the wiring B13b on the first electromagnetic valve 13 contact the electrical contacts of the wire A12a and the wire B12b at the front end of the water tank 2, and the first electromagnetic valve 13 is opened by a positive pulse current, and water flows out of the water outlet pile 4; when the water tank 2 moves away from the water outlet pile 4, the electrical contacts connecting the wiring A13a and the wiring B13b of the first electromagnetic valve 13 are exchanged with the electrical contacts of the wire B12b and the wire A12a at the rear end of the water tank 2, and the first electromagnetic valve 13 is closed by a reverse pulse current. Since the water outlet piles 4 are arranged at equal intervals on the water supply pipe 3, and the setting distance is equal to the length of the telescopic water tank, after the first electromagnetic valve 13 on the current water outlet pile 4 is closed, the first electromagnetic valve 13 on the next water outlet pile 4 is opened, and the water flow will not be interrupted, forming a continuous water supply.

[0050] Since the water supply pipe 3 is laid on the ground, the mobile sprinkler can use the water supply pipe 3 as a navigation route to achieve continuous self-propelled operation of the mobile sprinkler.

[0051] Specifically, the mobile sprinkler also includes a guide rod 36, which is retractably installed at the bottom of the frame 1 and located between the groove wheel 8 and the wheel 101 on the same side. A guide wheel 37 is provided at the lower end of the guide rod 36, and the guide wheel 37 is an H-shaped roller. The guide wheel 37 is placed on the water supply pipe 3 and can roll along the water supply pipe 3. Two trigger rods 38 are provided on both sides of the guide rod 36, and the two trigger rods 38 are fixedly installed at the bottom of the frame 1. The mobile sprinkler is provided with an automatic driving system, and the mobile sprinkler can also be provided with a satellite navigation system. Under normal driving conditions, there is a gap between the guide rod 36 and the trigger rod 38. When the mobile sprinkler travels to one side, the guide rod 36 will deviate and squeeze the trigger rod 38 on the side. The trigger rod 38 will send an electrical signal to the intelligent control cabinet 21, and the intelligent control cabinet 21 controls the automatic driving system to correct the driving direction, so that the mobile sprinkler always travels along the preset water supply pipe 3 to complete self-propelled sprinkler irrigation. For the convenience of driving, the middle part of the guide rod 36 is connected to the lifter 39 by a steel wire, one end of the steel wire connected to the lifter 39 is fixedly connected to the frame 1, and the other end of the steel wire connected to the lifter 39 is fixedly connected to the middle part of the guide rod 36. When the guide wheel 37 needs to be retracted, the steel wire of the steel wire connected to the lifter 39 is pulled to retract the guide wheel 37.

[0052] In this way, the water tank 2 on the mobile sprinkler is combined with the water supply pipe 4, so that the mobile sprinkler can obtain a continuous water source from the water tank 2 through the water supply pipe 4 while sprinkling, so that the mobile sprinkler can operate continuously for a long time without carrying a bulky reel or building a high-standard channel; the performance of the equipment and the convenience of operation are greatly improved, and the equipment cost is significantly reduced.

[0053] Embodiment 2:

[0054] The difference between this embodiment and the first embodiment lies in the installation position of the water supply pipe 3, the structure of the water outlet pile, the mobile power supply structure of the water tank 2 and the triggering structure of the solenoid valve.

[0055] In this embodiment, if Figures 5 to 7 As shown, the water supply pipe 3 is buried underground, and the water outlet pile 4 is a retractable water outlet pile, which is retracted underground when no water is discharged and extends out of the ground when water is discharged. A second solenoid valve 14 is provided at the bottom of the water outlet pile 4. The second solenoid valve 14 is a self-holding solenoid valve, and the second solenoid valve 14 is powered by a small solar panel 5; the second solenoid valve 14 is connected to a valve opener 16a and a valve closer 16b through a forward and reverse circuit, respectively, and the valve opener 16a and the valve closer 16b are buried on the ground. The trigger structure for opening and closing the second solenoid valve 14 is a front pressure control wheel 15a, a rear pressure control wheel 15b, a pressure control rod 160 and a pressure control spring 161, which are respectively arranged at the front end and the rear end bottom of the water tank 2.

[0056] When the front end of the water tank 2 passes through the water outlet pile 4, the front pressure-controlled wheel 15a presses the valve opener 16a that provides positive electricity, the pressure-controlled rod 160 is pressed down, the upper and lower pressure-controlled springs 161 contact, the valve opener 16a is connected, the second solenoid valve 14 receives a positive pulse current to open, and the water outlet pile 4 extends out of the ground under the action of water pressure and discharges water; when the rear end of the water tank 2 passes through the water outlet pile 4, the rear pressure-controlled wheel 15b presses the valve closing device 16b, the second solenoid valve 14 receives a reverse current to close, the water outlet pile 4 stops water, the water pressure disappears and drops back to the underground.

[0057] Since the water supply pipe 3 is buried underground, the automatic driving system and satellite navigation system provided on the mobile sprinkler can be used to realize self-propelled cruising irrigation according to the designed operation route.

[0058] Since the retractable water outlet pile 4 is retracted into the ground when not in use, the water outlet pile 4 does not affect other field operation machinery at ordinary times.

[0059] like Figure 8 As shown, two or more mobile sprinklers can work side by side. The specific method is to open the pipe covers 33 of the water spray pipes 23 of two adjacent mobile sprinklers and connect the water spray pipes 23 of the two adjacent mobile sprinklers together. In this way, only one water supply pipe 3 is required, and one sprinkler carries a mobile water tank 2. In combination with the application of a satellite navigation system and an automatic driving system, two or more mobile sprinklers can work side by side synchronously, thereby reducing the layout density of the water supply pipe 3, increasing the sprinkler spray width, and further reducing the cost of pipeline facilities.

[0060] The invention also discloses a continuous water supply sprinkler irrigation method using the continuous water supply sprinkler irrigation system.
