[0002] Irrigation is a technical measure to supply crops with water. In order to ensure normal growth of crops and obtain high and stable yield, sufficient water must be supplied to crops. Under natural conditions, the demand of crops for water cannot be met due to insufficient rainfall or uneven distribution. Therefore, artificial irrigation is necessary to make up for the deficiency of natural rainfall.

[0003] There are many types of irrigation, among which drip irrigation is a method of directly delivering water to the roots of crops through pipes and drippers, which is suitable for arid regions and crops with high economic value. A drip irrigation system usually consists of five parts: water source, filtration, water delivery pipe, dripper or drip irrigation tape, and control equipment.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Please refer to Figures 1-11 The present application provides a technical solution: an adjustable agricultural planting drip irrigation device, comprising a water tank 1 and a main water pipe 2, the water tank 1 is used for storing irrigation water, the main water pipe 2 is connected with the water outlet end of the water tank 1, a plurality of groups of oppositely distributed branch water pipes 3 are arranged on the main water pipe 2 at intervals, and a plurality of drippers 4 are arranged on the branch water pipes 3. ​

[0035] The dripper 4 includes a fixing plate 41 and a shell 42. The fixing plate 41 is sleeved on the outside of the shell 42 and is used to fix the shell 42 at the corresponding position of the branch water pipe 3. The shell 42 is a hollow structure. A water inlet 421 is provided at the upper end of the shell 42 and extends into the interior of the branch water pipe 3, which is used to introduce water flow into the branch water pipe 3. A bottom plate 422 is provided at the lower end of the shell 42, and a water outlet 423 is opened on the bottom plate 422. The water outlet 423 is connected to the dripper 424.

[0036] A drive shell 43 is fixed to the lower side of the bottom plate 422. A cleaning component is rotatably arranged inside the drive shell 43. A pipe 44 is connected between the drive shell 43 and the shell 42. A valve 441 is provided at the connection between the pipe 44 and the shell 42. A plurality of circular holes 431 are opened at the bottom of the drive shell 43.

[0037] In actual operation, the irrigation water in the water tank 1 is led out to the main water pipe 2, and the main water pipe 2 is divided into each branch water pipe 3. After the irrigation water enters each dripper 4, the dripper 4 drips the water into the soil near the roots of the crops at a small flow rate and evenly, thereby achieving precise irrigation; when the water outlet 423 or the dripper 424 is blocked and the valve 1 441 is opened, the water in the shell 42 will flow from the pipe 1 44 into the drive shell 43, and then flow out from the circular hole 431, replacing the irrigation function of the dripper 424; at the same time, the water flowing into the drive shell 43 will serve as the driving force of the cleaning component, causing the cleaning component to rotate relative to the drive shell 43.

[0038] like Figures 3-5 As shown, the cleaning assembly includes a rotating ring 45, with a plurality of blades 46 fixed to the circumference of the upper end of the rotating ring 45, and a plurality of brush heads 47 connected to the circumference of the lower end of the rotating ring 45. A force sensing module 471 is provided at the connection between each brush head 47 and the rotating ring 45. Preferably, the force sensing module 471 is provided with an annular frame, the outer side of the annular frame is fixedly connected to the inner diameter of the rotating ring 45, and a plurality of force-sensitive units are provided on the inner circumference of the annular frame, and the connection between the brush head 47 and the annular frame corresponds to each force-sensitive unit.

[0039] Supplementary explanations based on the above structure are as follows: the drive shell 43 cooperates with the rotating ring 45 to form an annular groove 432, and the blade 46 is located in the drive shell 43 and is set at a certain inclination angle. When water flows into the drive shell 43, it pushes the blade 46 to drive the rotating ring 45 to rotate; the brush head 47 is made of a harder material, such as PP polypropylene bristles, which has excellent acid and alkali corrosion resistance and chemical stability, low water absorption, and a relatively low price; the inward end of the brush head 47 extends into the water outlet range of the drip head 424. When the drip head 424 is in a normal drip irrigation state, the falling water droplets bring a downward impact force to the brush head 47, and are detected by the force sensing module 471. The blockage is determined based on the presence or absence of a force signal, and the water flow is adjusted based on the frequency of the force signal.

[0040] In one embodiment, the shell 42 is provided with an elastic diaphragm 48, the elastic diaphragm 48 is provided with a water flow passage towards one side of the pipeline I 44, the other side of the elastic diaphragm 48 is provided with a pipeline II 49, both ends of the pipeline II 49 are located on the upper side and the lower side of the elastic diaphragm 48 respectively, and the connection part of the pipeline II 49 located on the upper side of the elastic diaphragm 48 is provided with a valve II 491.

[0041] It needs to be explained that, as shown in Figure 4 , the elastic diaphragm 48 deforms according to the pressure state in the shell 42. When the water flow enters the shell 42, the water flow pressure will cause the elastic diaphragm 48 to deform. When the water pressure is high, the pressure on the elastic diaphragm 48 increases, which will shrink inward, that is, bend towards the water outlet 423, reduce the cross-sectional area of the water flow passage, and thus reduce the flow rate; on the contrary, when the water pressure is low, the elastic diaphragm 48 returns to its original state, increases the water flow passage area, and ensures sufficient water output. The pipeline II 49 is used to balance the pressure on the upper and lower sides of the elastic diaphragm 48, that is, if there is a large drip irrigation demand, in the case of ensuring high flow rate, by opening the valve II 491, the water flow is directly introduced from the upper side of the elastic diaphragm 48 to the lower side of the elastic diaphragm 48, which reduces the pressure difference between the upper and lower sides of the elastic diaphragm 48, so that the deformation amount of the elastic diaphragm 48 is reduced, the water flow passage area is increased, and at this time the water flow rate maintains a high flow rate, so that the water output is increased.

[0042] Further, as shown in Figure 6 , the shell 42 is provided with a simple flow detection assembly 5 for detecting the pressure in the shell 42, the flow detection assembly 5 includes a connecting plate 51, a plurality of springs 52 are fixed on the connecting plate 51, the other end of the spring 52 is connected with a pressure cover 53, the pressure cover 53 is in sliding fit with the connecting plate 51, and the connecting plate 51 is provided with a pressure sensing module at the connecting part of the spring 52.

[0043] In actual operation, when the water flow is introduced into the shell 42, a certain water pressure is generated, when the water pressure intensity increases, the water flow size also increases, when the water pressure is high, the fixed spring 52 at one end will generate an axial compression force, so that the pressure cover 53 moves downward relative to the connecting plate 51, the pressure sensing module detects the corresponding pressure signal, the stronger the water pressure, the greater the pressure. Preferably, the connecting plate 51 is provided with a sealing plate on both sides of the pressure cover 53, so that the inside of the pressure cover 53 is relatively closed, avoiding the water flow from both sides to invade the compression spring 52 to bring a reverse thrust, offsetting part of the downward pressure of the flowing water on the pressure cover 53, and improving the accuracy of pressure detection.

[0044] As shown in Figures 8-9 , the junction of the main water pipe 2 and the branch water pipe 3 is respectively provided with a flow guide plate 6, the flow guide plate 6 is vertically arranged on both sides and is provided with an arc at the connecting part, one side of the flow guide plate 6 is towards the corresponding branch water pipe 3, and the other side of the flow guide plate 6 is towards the fluid flow direction in the main water pipe 2.

[0045] Further, the branch water pipe 3 is rotatably arranged with a rotating shaft 31 on one side of the flow guide plate 6, the rotating shaft 31 is circumferentially arranged with a plurality of blades 32, the other end of the blade 32 is inclined towards the main water pipe 2, one end of the rotating shaft 31 extends out of the branch water pipe 3 and is arranged with a pointing mark 33, and the main water pipe 2 is arranged with a visual detection module 21 between each group of branch water pipes 3 for monitoring the rotating state of the pointing mark 33.

[0046] It should be noted that: when the water flows through the flow guide plate 6, part of the fluid flows from one side of the flow guide plate 6 to the branch water pipe 3, and the other part of the fluid flows from the other side of the flow guide plate 6 to the next group of branch water pipes 3. When the fluid flowing to the branch water pipe 3 passes through the blade 32, the blade 32 is pushed to drive the rotating shaft 31 to rotate, so that the pointing mark 33 rotates and is detected by the visual detection module 21. The blade 32 is used to assist in monitoring the flow state of the fluid on the water inlet side of the branch water pipe 3, to determine whether a blockage occurs.

[0047] As shown in Figure 1 , the water tank 1 is arranged with a water pump 7 at the connection with the main water pipe 2 for providing power.

[0048] As shown in Figures 10-11 , the water tank 1 is arranged with a water inlet pipe 11 on the upper side, and a filter assembly is arranged in the water tank 1, the filter assembly includes a boss 81, the boss 81 includes a table surface 811 and a flat surface 812, a plurality of filter holes 82 are formed in the flat surface 812 for filtering irrigation water, the table surface 811 is rotatably arranged with a rotating shaft 83, one end of the rotating shaft 83 is connected with a motor 84, and the rotating shaft 83 is connected with a paddle 85.

[0049] Further, the paddle 85 is arranged in cooperation with the shapes of the table surface 811 and the flat surface 812, and one end of the paddle 85 located on the flat surface 812 is arranged with a scraper 86.

[0050] In actual operation, after the irrigation water is introduced into the water tank 1 through the water inlet pipe 11, the water body is sieved through the filter holes 82 of the flat surface 812 to screen out impurities that may cause pipeline blockage. When the motor 84 is started, the rotating shaft 83 is driven to rotate, so that the scraper 86 rotates along the surface of the flat surface 812, thereby achieving the effect of dredging the filter holes 82.

[0051] It should be noted that: the filter assembly is used to eliminate the blockage of the irrigation water introduced into the water tank 1, the pointing mark 33 is used to troubleshoot the blockage of the connection between the branch water pipe 3 and the main water pipe 2, and the cleaning assembly is used to troubleshoot the blockage of the dripper 4. The three-stage blockage troubleshooting improves the overall quality of the drip irrigation device.

[0052] The specific implementation method is as follows:

[0053] Step 1: filtering, irrigation water is introduced into the water tank 1 and temporarily stored after being filtered by the filter assembly.

[0054] Step two: water delivery, water pump 7 pumps the irrigation water in water tank 1 to main water pipe 2.

[0055] Step three: water distribution, irrigation water in main water pipe 2 is distributed to each branch water pipe 3 through guide plate 6.

[0056] Step four: drip irrigation, irrigation water in branch water pipe 3 enters each dripper 4 to complete drip irrigation.

[0057] Specifically, in step three, visual detection module 21 determines whether the corresponding branch water pipe 3 is blocked according to the rotation state of each pointer 33, that is, if the connection between a branch water pipe 3 and main water pipe 2 is blocked, the internal waterway is not open, vane two 32 cannot rotate, and the corresponding pointer 33 remains stationary.

[0058] Further, the complete rotation of pointer 33 is taken as the judgment limit, that is, if pointer 33 can rotate a full circle, there is no obstruction in the rotation range of vane two 32, and the connection between branch water pipe 3 and main water pipe 2 is not blocked. If pointer 33 cannot rotate a full circle, the rotation amplitude of pointer 33 is taken as the judgment standard of the degree of blockage, the more the blockage, the more difficult it is to rotate pointer 33. When the connection between branch water pipe 3 and main water pipe 2 is completely blocked, vane two 32 cannot rotate, and pointer 33 remains stationary.

[0059] Further, according to the rotation speed of pointer 33, the flow rate of fluid in branch water pipe 3 is determined. That is, the faster the rotation speed of the corresponding pointer 33, the faster the internal flow rate of branch water pipe 3.

[0060] In step four, the detection method for the blockage of dripper 4 is as follows: before determining that dripper 4 is blocked, the pointer 33 of the corresponding branch water pipe 3 is detected to determine whether the branch water pipe 3 is blocked, and if the branch water pipe 3 is not blocked, the dripper 4 is detected. When dripper 4 is working normally, the falling water droplets fall through brush head 47, force sensing module 471 detects the corresponding falling force, and the frequency of the force signal is equal to the frequency of the falling water droplets. If dripper 4 is blocked, there are no water droplets or the water droplets fall too slowly, force sensing module 471 cannot detect the downward force signal or the detected force signal interval is too long, and the judgment standard is set by man.

[0061] Under normal circumstances, force sensing module 471 can detect a number of force signals consistent with the number of brush heads 47 at a time, and if the number of force signals is less than the number of brush heads 47, it indicates that the internal water flow passage area of dripper 4 is small, so that the volume of each falling water droplet cannot completely cover all brush heads 47. Or the dripper head 424 is partially blocked, so that a number of brush heads 47 are wrapped by the blockage and cannot detect the falling force of the water droplets. At this time, the pressure signal detected by pressure sensing module should be compared, a critical pressure value P is set, and the real-time pressure signal detected is p.

[0062] When p≥P, the internal pressure of the dripper 4 is higher than the ideal range, the deformation of the elastic diaphragm 48 is large, and the water flow passage area is small. At this time, the volume of each water droplet that falls cannot cover all the brush heads 47;

[0063] When p<P, the internal pressure of the dripper 4 is in the ideal range, the deformation of the elastic diaphragm 48 does not have too much influence on the water flow passage area. At this time, the volume of each water droplet that falls can cover all the brush heads 47.

[0064] On the basis of the above, if p<P and the force sensing module 471 detects a number of force signals less than the number of brush heads 47 at one time, it indicates that the surface dripper head 424 is partially blocked. The degree of blockage is inversely proportional to the number of force signals, that is, the more the brush heads 47 wrapped by the blocked object, the fewer the force signals that can be detected.

[0065] If p≥P, then whether a water droplet falls within a unit of time is used as a basis for judging blockage.

[0066] For the case of blockage of the dripper 4, the following method is used to try to unblock: If the flow detection assembly 5 detects that the flow in the dripper 4 is too large, so that the pressure on the upper side of the elastic diaphragm 48 is too large, so that the water flow passage area is too small, corresponding to p≥P and no water droplet is detected to fall. At this time, valve two 491 is opened, the pressure difference between the upper and lower sides of the elastic diaphragm 48 is reduced, the deformation of the elastic diaphragm 48 is reduced, the water flow passage area is increased, the flow is increased, and the effect of unblocking is achieved by using high-flow irrigation water to break through the blockage of the dripper 4.

[0067] If the above operation does not work, valve one 441 is opened, and the water flow in the dripper 4 is introduced into the drive shell 43. The water flow flows out through the circular hole 431, temporarily replacing the irrigation function of the dripper head 424. At the same time, the water flow drives the blade one 46 to rotate the rotating ring 45, so that the brush head 47 starts to rotate, thereby removing the wrapped state of the blockage, loosening the whole blockage, and cleaning the dripper head 424. Further, part of the water droplets flowing out of the circular hole 431 fall on the brush head 47, spread along the surface of the brush head 47 to the blockage, and play a role of wetting. If the dripper head 424 is blocked by dry soil, wetting can reduce the difficulty of unblocking.
