[0004] Existing alternating irrigation equipment uses irrigation pipes of different diameters and depths for irrigation.

The spirally arranged pipes will make the pipes longer when irrigating the surface of the plant roots, and the area occupied by the ground soil layer will also increase. The number and cost of valves arranged on the surface will also increase accordingly, which is not conducive to the comprehensive control of irrigation costs. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to perform cost-controlled alternating irrigation treatment on different root zones of plant roots without affecting the normal growth of the root system under the soil layer.

[0009] As a further improvement of the present application, the surface of the shield is provided with symmetrically arranged arc-shaped notches, and the height of the arc-shaped notches is not less than the sum of the thicknesses of the upper rack and the lower rack. The upper rack and the lower rack are of equal length and are connected to the upper rack and the bracket.

[0010] As a further improvement of the present application, the upper rack is located above the lower rack, and the line connecting the positions where the two brackets are connected to the water pipe passes through the center of the circle where the water pipe is located.

[0011] As a further improvement of the present application, the height of the magnetic plug block is greater than the depth of the lower slide groove and less than the depth of the upper slide groove, and the electromagnetic block is not powered in the initial state.

[0012] As a further improvement of the present application, the center of the driving gear is located on one side of the center of the water pipe, and two water outlet nozzles on the same axis in the water pipe are opened at the same time.

[0013] As a further improvement of the present application, it also includes an alternatingly controlled irrigation system, which includes a driving module, an irrigation module and a variable module.

The variable module is connected to the electromagnetic block signal to avoid the change of the variable rack.

Before a rainstorm comes, the interception cover can be clamped to prevent the soil on the field surface from being washed away by the water flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1-2The present invention shows a root zone alternating irrigation device for melon planting, comprising a plurality of water pipes 1 arranged equidistantly and laid on the surface of a field, the surfaces of two adjacent water pipes 1 are connected through a connecting hose, a water inlet pipe is installed through the surface of the leftmost water pipe 1, four water outlet nozzles 2 are installed equidistantly on the inner surface of each water pipe 1, an adjustment unit is installed on the inner side of each water pipe 1, the adjustment unit comprises a support column 4 inserted in the field, a protective cover 3 is installed on the top of the support column 4, a driving motor 5 is installed inside the protective cover 3, an output end of the driving motor 5 is connected to a driving gear 7, both sides of the driving gear 7 are respectively meshed and connected with variable racks 6, and the tail ends of the two variable racks 6 are respectively fixedly connected to the top surface of the water pipe 1 through brackets;

[0037] Figure 5-7 As shown, the variable rack 6 includes an upper rack 61 and a lower rack 62 arranged up and down, and there is an overlapping area at the ends of the upper rack 61 and the lower rack 62 that are close to each other, and a self-resetting damping shaft 63 is installed through the overlapping area, and an upper slide groove and a lower slide groove are respectively provided inside the upper rack 61 and the lower rack 62 in the overlapping area, and an electromagnetic block 64 is fixedly installed on the top wall of the upper slide groove, and a magnetic plug block 65 that attracts the electromagnetic block 64 is installed on the inner wall of the upper slide groove, and the magnetic plug block 65 is slidably connected to the inside of the lower slide groove.

[0038] The center of the driving gear 7 is located on one side of the center of the water pipe 1, and the two water outlet nozzles 2 on the same axis in the water pipe 1 are opened at the same time.

[0039] Specifically, when using the present application to perform alternating root zone irrigation of melons, the melon plants need to be planted on the field ridges first, and then the water pipe 1 is put on the outside of each melon plant one by one, and then the end of the water inlet pipe that is not connected to the water pipe 1 is connected to the water source or the fertilizer end, in preparation for subsequent root irrigation or fertilization treatment.

[0040] When performing root zone irrigation, the driving motor 5 is used to drive the driving gear 7 to rotate, and drive the variable racks 6 to move away from each other, so that the water pipe 1, which is initially circular, becomes an ellipse (the long axis of the ellipse is parallel to the width direction of the field, such as Figure 3 As shown in the figure, at this time, the two water outlet nozzles 2 at both ends of the long axis of the elliptical water pipe 1 are far away from the main root of the plant, and the two water outlet nozzles 2 on the short axis are close to the main root of the plant. At this time, the two water outlet nozzles 2 at both ends of the long axis or the two water outlet nozzles 2 on the short axis or four water outlet nozzles 2 can be selected to be turned on to form different irrigation areas. Then the driving motor 5 rotates in the opposite direction, driving the driving gear 7 to rotate, driving the variable racks 6 to approach each other, so that the water pipe 1 is deformed into an ellipse again (the long axis of the ellipse is parallel to the length direction of the field, as shown in the figure). Figure 4As shown), at this time, the two water outlet nozzles 2 at both ends of the long axis of the elliptical water pipe 1 are far away from the main root of the plant, and the two water outlet nozzles 2 on the short axis are close to the main root of the plant, and then corresponding supplementary adjustments are made to form staggered irrigation in different root zones.

[0041] Compared with the prior art, the present application avoids the operation of deep burying of pipes, which can ensure the normal growth of plant roots in the lower soil. In addition, for the water pipe 1 with a spiral winding design, the water pipe 1 is deformed by changing the movement of the rack 6 to adjust the changes in each irrigation area, thereby realizing alternating irrigation of root zones and reducing the installation cost of valves and water pipes 1.

[0042] The upper rack 61 is located above the lower rack 62 , and the line connecting the positions where the two brackets are connected to the water pipe 1 passes through the center of the circle where the water pipe 1 is located.

[0043] Specifically, the connecting line between the ends of the two brackets coincides with the diameter of the center of the water pipe 1 in the vertical direction, so that when the variable rack 6 moves, it can drive the water pipe 1 to perform a more regular elliptical change, thereby achieving a more uniform irrigation operation.

[0044] The height of the magnetic plug 65 is greater than the depth of the lower slide groove and less than the depth of the upper slide groove. In the initial state, the electromagnetic block 64 is not powered.

[0045] It also includes an alternating control irrigation system, which includes a driving module, an irrigation module and a variable module. The driving module is connected to the driving motor 5 by signal, and is used to control the movement state of the two variable racks 6 and adjust the irrigation area of ​​the water outlet nozzle 2. The irrigation module is connected to the water outlet nozzle 2 by signal, and controls the number of water outlet nozzles 2 on the same water pipe 1 that are opened. The variable module is connected to the electromagnetic block 64 by signal, and is used to avoid the change of the variable rack 6.

[0046] The change rack 6 change avoidance operation includes the following steps:

[0047] S1. When a tiller is used to loosen the soil along a field ridge in a straight line, the driving module is used to control the water pipe 1 to deform into an ellipse, and the long axis of the ellipse is parallel to the direction of the field ridge;

[0048] S2, start the electromagnetic block 64, drive the magnetic plug 65 to move up and disengage from the slide groove, when the ripper passes the lower rack 62, due to the pushing effect of the ripper, the lower rack 62 is driven to deflect and avoid, so that the ripper can move normally, and then the lower rack 62 is reset on the self-resetting damping shaft 63;

[0049] S3, the electromagnetic block 64 is powered off, and the magnetic plug block 65 moves down to the lower sliding groove to constrain the upper rack 61 and the lower rack 62.

[0050] The surface of the shield 3 is provided with symmetrically arranged arc-shaped notches, and the height of the arc-shaped notches is not less than the sum of the thicknesses of the upper rack 61 and the lower rack 62. The upper rack 61 and the lower rack 62 are of equal length and are connected to the bracket with the upper rack 61.

[0051] Specifically, during irrigation, in order to prevent the soil in the field from becoming compacted, which may cause subsequent water absorption or fertilizer absorption to be poor, a tiller (which is a prior art and will not be elaborated on) will be used to loosen the soil on both sides of the plants on the field. During this process, in order to prevent the circular water pipe 1 from affecting the movement of the tiller (that is, part of the circular water pipe 1 is exposed to the moving path of the tiller), it is necessary to first deform the water pipe 1 into an ellipse (the long axis of the ellipse is parallel to the length direction of the field), so that part of the water pipe 1 retracts to avoid overlapping with the subsequent moving path of the tiller.

[0052] When moving, the ripper will come into contact with the lower rack 62 and intercept. At this time, the electromagnetic block 64 needs to be started to drive the magnetic plug block 65 to move upward, so that the upper rack 61 and the lower rack 62 can be non-fixedly constrained by the self-resetting damping shaft 63. When the ripper moves through the lower rack 62, it can push the lower rack 62, so that the lower rack 62 is deflected, which has an avoidance effect, so that the ripper can perform the mobile loosening operation normally (such as Figure 8 shown).

[0053] Subsequently, the electromagnetic block 64 is powered off, causing the magnetic plug block 65 to move downward, thereby inserting the magnetic plug block 65 into the lower slide groove and part of the upper slide groove, and cooperating with the self-resetting damping shaft 63 to form a constrained connection, so that the upper rack 61 and the lower rack 62 can form a stable straight bar design.

[0054] The second implementation method:

[0055] Fig. 9 It is shown that several adjustment units are replaced by one adjustment unit, and the adjustment unit is arranged on one side of all water pipes 1, the top surfaces of several water pipes 1 are connected by a cross bar 8, and one end of the top surface of the cross bar 8 is connected to the end of the variable rack 6 by a connecting rod.

[0056] An interception cover 9 is inserted into the top of the cross bar 8 through a snap-in groove, and both ends of the interception cover 9 are connected to sealing plates with built-in drainage outlets.

[0057] Different from the first embodiment, in this embodiment, a driving motor is used to drive multiple water pipes 1 connected to the cross bar 8 to move synchronously, so as to achieve the same deformation effect of the water pipe 1 as in the first embodiment, reduce the use of the driving motor 5, further reduce the cost, and reduce the space occupied near the plant.

[0058] Specifically, the horizontal bar 8 can be used to drive multiple water pipes 1 on a field to deform as a whole, so as to perform corresponding root zone alternating irrigation treatment (such as Fig.10 shown).

[0059] During the growth of plants, if there is sudden rainfall, if the plants in the field are in the seedling stage, if the rainfall is heavy and sudden, the soil on the field will be washed away, affecting the subsequent growth of the plants. It will take manpower to fill the washed away soil back to the field, which is not conducive to the normal growth of the plants.

[0060] Therefore, before rainfall, the water pipe 1 is transformed into an elliptical shape (the major axis of the ellipse is parallel to the width direction of the field ridge), so that the end of the variable rack 6 is as close to the edge of the field ridge as possible, and then the interception cover 9 is clamped on the surface of the cross bar 8, and the other end of the interception cover 9 is inserted into the soil layer of the field ridge near the ditch. After that, even if soil erosion occurs, the washed away soil will be intercepted by the interception cover 9, and the internal water will be discharged through the drain. After the rainfall is over, the soil in the interception cover 9 can be regularized into the field ridge. Compared with collecting disorderly scattered soil after scouring, fixing and regularizing the soil in the interception cover 9 is more convenient and labor-saving (such as Fig.11 shown).

[0061] In summary, the present application utilizes the movement of the variable rack 6 to drive the water pipe 1 to deform to different degrees to control the drip irrigation area of ​​the water outlet nozzle 2, thereby achieving the purpose of alternating irrigation of the root zones of melons planted inside the water pipe 1. In addition, when a tiller is used to loosen the soil in a field planted with melons, the water pipe 1 is deformed and the variable rack 6 is effectively avoided, so that the tiller can effectively loosen the soil in the field. After that, the cooperation of the cross bar 8 and the interception cover 9 can reduce the use of the drive motor 5, and two cross bars 8 can be used to achieve bidirectional deformation of the water pipe 1 on the entire field surface, and before a rainstorm comes, the interception cover 9 can be clamped to prevent the soil on the field surface from being washed away by the water flow.

[0062] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
