Description

Technical Field

[0001] The invention relates to the field of agricultural sprinkler irrigation, and in particular to a slope mobile sprinkler irrigation machine, 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 a pipe system or a natural water source to spray water with a certain pressure into the air, which then falls on plants and the ground in the form of small droplets or mist. Sprinkler irrigation includes fixed sprinkler irrigation, semi-fixed sprinkler irrigation and mobile sprinkler irrigation, which has the characteristics of saving water, not damaging soil structure and strong adaptability.

[0003] Mobile sprinkler irrigation is the current development trend of agricultural sprinkler irrigation, and the application of mobile sprinklers in large fields is becoming more and more widespread. There are two types of water supply for mobile field sprinkler irrigation: pipeline water supply and trench water supply. Mobile field sprinklers mainly include reel-type mobile 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 towed by a tractor to pull the pipe to spray water. However, 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 pipe placement and transfer process require tractor traction. For example, 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, realizes self-propelled water spraying operation, and releases 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 usually uses trenches for water supply. 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. For example, a patent application with publication number CN108207581A discloses a lightweight, simplified, intelligent, self-propelled, translational cantilever mobile sprinkler, which is provided with a suction pipe assembly and a power pump assembly on a traveling frame. The suction pipe assembly and the power pump assembly cooperate to pump water in the ditch, and the sprinkler irrigation operation is completed through the sprinkler irrigation assembly, thus overcoming the problem that large sprinkler irrigation machines are not suitable for small plots of land. However, there is no better solution to the problem that it is difficult to achieve continuous water supply in channels for irrigation on slopes. Summary of the invention

[0041] Embodiment 1:

[0042] like Figures 1 to 5 As shown, the present invention discloses a mobile sprinkler for slope land, comprising a frame 1 and an arm mounted on the frame 1, an irrigation pump 7 and a power assembly 17, wherein the arm is mounted above the frame 1, and a water spray pipe 21 is arranged on the arm, and the power assembly 17 is used to provide a power source, and the intelligent control cabinet 21 can be controlled by a mobile phone or a computer terminal through wireless signal transmission, Bluetooth signal transmission, etc. A water suction pipe 8 is arranged on the irrigation pump 7, and the lower end of the water suction pipe 8 extends into the groove 2, and a plurality of partition walls 5 are arranged in the groove 2, and the channel edge of the groove 2 is a channel edge with an obstacle-free and smooth transition, and a ramp rack 6 is installed on the channel edge, and a climbing gear 10 meshing with the ramp rack 6 is arranged at the bottom of the frame 1, and the ramp rack 6 is preferably a metal rack, and the climbing gear 10 is preferably a metal gear, which has higher strength.

[0043] In this way, the partition 4 divides the groove 2 into multiple sections of stepped water storage grooves. When the slope mobile sprinkler moves on the slope, it can absorb the stored water in the groove 2 through the irrigation pump 7 and the suction pipe 8. When climbing a steep slope, the climbing gear 10 meshes and rolls with the slope rack 6 on the groove 2 to exert force on the uphill climb.

[0044] In this solution, the climbing gear 10 is controlled to be retracted and extended by the hydraulic rod 11, and the hydraulic rod 11 is connected to the power assembly 17 through the hydraulic pipe 12. The specific solution is that when on flat ground, the climbing gear 10 is retracted, and when walking on a slope, the climbing gear 10 is pushed by the hydraulic rod 11 and meshes with the slope rack 6 on the groove 2 and rolls, and exerts force to go uphill. After the uphill is completed, the hydraulic rod 11 is retracted, and the climbing gear 10 of the mobile sprinkler leaves the slope rack 6 of the groove 2, and the mobile sprinkler resumes normal travel.

[0045] In order to make the mobile sprinkler move along the groove 2 without deviation, the mobile sprinkler also includes a guide rod 13 and a wire connection lifter 16. The upper end of the guide rod 13 is rotatably mounted on the bottom of the frame 1. The lower end of the guide rod 13 is provided with a guide wheel 14. The guide wheel 14 is an H-shaped roller. The guide wheel 14 can be stuck on the channel edge of the groove 2 and roll. The guide wheel 14 is limited to run on the channel edge of the groove 2 and plays a navigation role. The wire connection lifter 16 is controlled by the power of the power assembly 17, and the wire connection lifter 16 is driven to retract and release the guide rod 13. Specifically, the first wire wheel of the wire connection lifter 16 is controlled by the power of the power assembly 17. One end of the pull rod line of the wire connection lifter 16 is fixed on the first wire wheel, and the other end is fixed on the guide rod 13. The first wire wheel is rotated to roll the pull rod line to retract and release the guide rod 13.

[0046] Generally speaking, the mobile sprinkler is also provided with a satellite navigation receiving antenna 34 and an automatic driving controller 35, which are used to perform satellite navigation and automatic driving on the mobile sprinkler. The satellite navigation receiving antenna 34 and the automatic driving controller 35 are both connected to the intelligent control cabinet 21 and controlled by the intelligent control cabinet 21. Two trigger rods 15 are also provided at the bottom of the upper frame 1 of the mobile sprinkler. The two trigger rods 15 are respectively located on the left and right sides of the guide rod 13. The trigger rods 15 are used to provide feedback on the touch of the guide rod 13 to adjust the moving direction of the mobile sprinkler. The trigger rods 15 are connected to the intelligent control cabinet 21. Specifically, when the mobile sprinkler is driving normally, there is a gap between the trigger rod 15 and the guide rod 13; when the mobile sprinkler is driving to one side, the guide rod 13 will touch the trigger rod 15 on one side, and the trigger rod 15 will be fed back to the intelligent control cabinet 21. The intelligent control cabinet 21 controls the mobile sprinkler to automatically correct the driving direction through the automatic driving controller.

[0047] A third opening and closing plug 8b controlled by a third float 8a is provided at one end of the suction pipe 8 extending into the groove 2; the third float 8a controls the third opening and closing plug 8b to open, and the mobile sprinkler draws water from the groove 2 through the irrigation pump 7 and the suction pipe 8. When the suction pipe 8 leaves the water surface and goes over the partition wall 5, the third float 8a controls the third opening and closing plug 8b to close, thereby ensuring that the water in the suction pipe 8 is not lost in the process of going over the partition wall 5.

[0048] In this solution, the water suction pipe 8 is made of a flexible material, and the partition wall 5 is made into a smooth surface, so that the water suction pipe 8 can smoothly pass over the partition wall 5 in the groove 2.

[0049] In one embodiment, the water suction pipe 8 can be only arranged at the front side or the rear side of the frame 1; in another embodiment, the number of the water suction pipes 8 is two, and the two water suction pipes 8 are respectively arranged at the front side and the rear side of the frame 1. The third opening and closing plug 8b of one water suction pipe 8 is closed when it climbs over the partition wall 5, and the third opening and closing plug 8b of the other water suction pipe 8 is usually in an open state in the water, so the sprinkling of the mobile sprinkler will not be interrupted.

[0050] The slope mobile sprinkler also includes a frame 1 and a central axis tube 22 installed on the frame 1, a fertilizer and medicine pump 18, a fertilizer and medicine configuration box 20 and an intelligent control cabinet 21. At least two pairs of wheels 101 are installed under the frame 1. The two wheels 101 in each pair of wheels 101 are respectively installed on the left and right sides under the frame 1. The power assembly 17 can control the movement of the wheels 101. The intelligent control cabinet 21 connects and controls the irrigation pump 7 and the power assembly 17. The fertilizer and medicine pump 18 is used to draw fertilizers and medicines from the fertilizer and medicine configuration box 20. The intelligent control cabinet 21 is also connected and controls the fertilizer and medicine pump 18.

[0051] The boom of the mobile sprinkler is composed of a multi-section truss. Generally speaking, the left and right sides of the boom are respectively composed of three sections of trusses spliced ​​together by a folder 29, so that the three sections of trusses on the left and right sides of the boom can be folded and retracted.

[0052] A water spray pipe 23 and a fertilizer and drug spraying pipe 24 are arranged on the expansion arm, a plurality of small nozzles 25 are installed on the water spray pipe 23, a middle nozzle 26 is installed at each end of the water spray pipe 23, a pipe cover 33 is installed at each end of the water spray pipe 23, the middle part of the water spray pipe 23 is fixedly connected to the frame 1 through a central axis tube 22, the central axis tube 22 is connected with the water spray pipe 23, a large nozzle 27 is installed at the top of the central axis tube 22, a turntable 221 is provided in the middle part of the central axis tube 22, and the lower end of the central axis tube 22 is connected to the irrigation pump 7 through a water pump outlet pipe 9; a plurality of fertilizer and drug spraying nozzles 19 are installed on the fertilizer and drug spraying pipe 24.

[0053] The large sprinkler 27 and the two medium sprinkler 26 can realize supplementary irrigation at different distances and in different ranges; on irregular plots or plots with large elevation differences, full-circle sprinkler irrigation can be performed with the large sprinkler 27 as the center. The water control valve 28 is respectively installed on the water spray pipe 23, the fertilizer spray pipe 24, the small sprinkler 25, the large sprinkler 27 and the medium sprinkler 26. The intelligent control cabinet 21 is connected to the water control valve 28 and controls the water control valve 28. The water control valve 28 has a built-in water outlet sensor. When the water control valve 28 is opened, if the water outlet sensor cannot sense water, a water shortage signal is issued.

[0054] A support rod 30 and a nozzle pull line 31 are provided on the expansion arm to maintain the balance and stability of the expansion arm. A rotatable camera 32 is installed on the top of the support rod 30. The camera 32 is connected to the intelligent control cabinet 21 and can rotate 360°.

[0055] This embodiment also provides a slope continuous water supply sprinkler system, including a groove 2 and a slope mobile sprinkler as described above, wherein the groove 2 is continuously arranged on the slope, and the groove 2 is supplied with water by a water supply pipe 3, and the water supply pipe 3 is a fixed water pipe pre-buried underground.

That is, when the water level in the groove 2 drops to the low water level line, the first float 4a controls the first opening and closing plug 4b to open, and the first water outlet pile 4 discharges water, and the position of the first float 4a rises as the water level in the groove 2 rises, until the first float 4a rises to the high water level line, the first float 4a controls the first opening and closing plug 4b to close, and the water outlet of the first water outlet pile 4 is closed.

[0057] In the second scheme, the water supply pipe 3 can be provided with a first water outlet pile 4 only at one or more grooves 2 at high points, and a water outlet can be provided at the bottom of the partition wall 5. The water outlet of the partition wall 5 is provided with a second opening and closing plug 5b controlled by a second float 5a. When the stepped water storage groove at the low point is short of water, the second float 5a on the partition wall 5 above it moves downward under the influence of gravity, controlling the second opening and closing plug 5b to open, and the water outlet of the partition wall 5 opens, and water flows from the upper-level stepped water storage groove to the stepped water storage groove, thereby achieving a constant water level in each stepped water storage groove.

[0058] Embodiment 2:

[0059] When the slope mobile sprinkler is used on a gentle slope or flat land, a pipeline is combined with a mobile water tank to achieve continuous water supply and irrigation without building a channel, thus saving construction costs. Figures 6 to 8 As shown, the slope mobile sprinkler also includes a water trough 36, which is hung under the frame 1, and the water suction pipe 8 extends into the water trough 36 to absorb water; the water trough 36 is a retractable water trough, including a retractable trough frame 38, a trough liner 39, a trough wheel 40, a tightening line 41 and a second line wheel 42, and the left and right sides of the trough frame 38 are respectively formed by a plurality of X-shaped metal components that are movably connected, and the X-shaped metal components on the left and right sides are connected by a plurality of cross bars, and the trough liner 39 is placed in the trough frame 38 to form a water storage space. Generally speaking, the trough liner 39 is made of waterproof cloth. The connecting frame 43 is fixedly installed below the frame 1, the front part of the water tank 36 is hung on the connecting frame 43, the second wire wheel 42 is controlled by the power of the power assembly 17, one end of the tightening wire 41 is fixed to the tail of the water tank 36, and the other end is fixed to the second wire wheel 42, and the tightening wire 41 is rolled up by rotating the second wire wheel 42 to drive the water tank 36 to shrink or stretch. In this way, when driving on flat ground, the present slope mobile sprinkler can absorb water from the water tank 36 through the branch pipe of the irrigation pump 7 and the water suction pipe 8 to irrigate.

[0060] The water supply pipe 3 located on a gently sloping land or flat land is laid on the ground surface. A solenoid valve 45 for controlling water outlet is provided on the second water outlet pile 37. The solenoid valve 45 leads to wiring A45a and wiring B45b. Wires A44a and wires B44b are provided on the outer side of the wall of the water tank 36. The two wires are connected from the positive and negative poles of the power supply device in the power assembly 17. The two wires are provided with two electrical contacts at the front end and the rear end of the water tank 36 respectively. The two wirings of the solenoid valve 45 are also provided with two electrical contacts. When the water tank 36 is close to the second water outlet pile, 37, the electrical contacts connecting the wiring A45a and the wiring B45b on the solenoid valve 45 correspond to the electrical contacts of the wire A44a and the wire B44b at the front end of the water tank 36, the solenoid valve 45 obtains a positive pulse current to open, and the second water outlet pile 37 discharges water; when the water tank 36 drives away from the second water outlet pile 37, the electrical contacts connecting the wiring A45a and the wiring B45b of the solenoid valve 45 correspond to the electrical contacts of the wire B44b and the wire A44a at the rear end of the water tank 36, and the solenoid valve 45 obtains a reverse pulse current to close.

[0061] Since the second water outlet piles 37 are equidistantly arranged on the water supply pipe 3, and the distance between them is equal to the length of the telescopic water trough, when the solenoid valve 45 on the first second water outlet pile 37 is closed, the solenoid valve 45 on the second second water outlet pile 37 is opened next, and the water flow will not be interrupted, thus forming a continuous water supply.

[0062] In this way, the water tank 36 on the mobile sprinkler is combined with the water supply pipe 3, so that the mobile sprinkler can obtain a continuous water source from the water tank 36 through the water supply pipe 3 while irrigating, so that the mobile sprinkler can operate continuously for a long time and the cost of channel construction can also be saved.

[0063] At the same time, the mobile sprinkler uses the water supply pipe 3 as a navigation route, that is, the guide wheel 14 can be stuck in the water supply pipe 3 and can roll along the water supply pipe 3, combined with the automatic driving controller, to achieve continuous self-propelled operation of the mobile sprinkler.

[0064] In this embodiment, the outer wheel tracks of the groove wheels on the left and right sides of the water trough 36 are smaller than the inner wheel tracks of the wheels 101 on both sides of the sprinkler 1, the water supply pipe 3 and the second water outlet pile 37 are located between the groove wheel 10 and the wheel 101 on the same side, and the distance between the outer side of the groove wheel arranged on one side of the water supply pipe 3 and the wheel 101 of the slope mobile sprinkler vehicle leaves enough space for arranging the water supply pipe 3 and the second water outlet pile 37. The height of the water trough 36 is also smaller than the height below the frame 1 of the slope mobile sprinkler vehicle. The water outlet of the second water outlet pile 37 extends above the water trough 36, and the top of the second water outlet pile 37 is located below the frame 1. In this way, the slope mobile sprinkler can pass through and operate on flat ground without hindrance.

[0065] Generally speaking, the second water outlet piles 37 are arranged at equal intervals, and the length of the water trough 36 is equal to or slightly greater than the distance between the two second water outlet piles 37 .

[0066] When used on flat ground or gently sloping ground, the power assembly 17 drives the hydraulic rod 11 through the hydraulic pipe 12 to retract the climbing gear 10 .

[0067] In this solution, two or more mobile sprinklers can also work side by side, such as Fig. 9 As shown, the specific method is that the pipe cover 33 of the water spray pipe 23 of two adjacent mobile sprinkler irrigation machines can be opened, and the water spray pipes 23 of the two adjacent mobile sprinkler irrigation machines can be connected together through a connecting pipe. In this way, only one water supply pipe 3 is needed to realize the sprinkler irrigation of two or more mobile sprinkler irrigation machines, thereby reducing the layout density of the water supply pipe 3 and the groove 2 and increasing the sprinkler irrigation width. On flat land, only one water supply pipe 3 is needed to provide water for the main machine, and on sloped land, only one water supply pipe 3 and the groove 2 are needed to provide water for the main machine. Sprinkler irrigation machines other than the main machine no longer need to lay pipes and grooves, thereby reducing the layout density of the water supply pipe 3 and the groove 2, increasing the sprinkler irrigation width, and further reducing the cost of pipeline facilities and grooves.

[0068] The present solution also discloses a sprinkler irrigation method of the continuous water supply sprinkler irrigation system as described above.
