Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural irrigation, and particularly relates to an irrigation spraying device and a using method for agricultural breeding. Background Art

[0002] Fertigation machine: Set irrigation and fertilization parameters through a controller, such as irrigation time, fertilization amount, fertilizer concentration, etc.; the water pump pumps water from the water source to the main pipeline. At the same time, the fertilizer applicator extracts fertilizer from the fertilizer tank according to the set fertilization amount and mixes it fully with water in the mixer to form a fertilizer-water mixture. Finally, the mixture is transported through the pipeline to the field sprinkler and evenly sprayed onto the soil around the crop roots in the set manner and flow rate;

[0003] Improper use, that is, during use, it collides with sharp objects (such as contact with metal edges, stones or gravel, etc.), and the user moves, drags or transports the pipeline during the specific implementation process;

[0004] Pressure change: Internal pressure. When the fertigation machine is working, the pressure inside the system is unstable, fluctuates frequently or is impacted by instantaneous high pressure. The hose bears a large pressure change, resulting in local depressions on the outer wall of the hose. Over time, wrinkles will form;

[0005] External pressure. Dust, soil and other impurities accumulate on the outer wall of the hose for a long time. The aforementioned substances absorb moisture in the external environment, and finally, under the action of gravity, they continuously accumulate on the outer wall of the pipeline until wrinkles or depressions appear on the outer wall of the pipeline;

[0006] When wrinkles or depressions appear on the distal hose, the normal flow boundary layer of the fluid inside the hose is damaged, and at the same time, the internal flow cross-sectional area will change; that is, under normal circumstances, the fluid inside the hose is close to the laminar flow state and flows smoothly; however, when wrinkles or depressions appear, eddies and irregular flows continuously occur in the aforementioned concave or wrinkled areas of the fluid. The eddies interact with the mainstream fluid, and the flow direction and speed of the fluid change violently in the local area, resulting in an increase in fluid energy loss, causing the fluid flow state to change, and at the same time triggering turbulence, thereby affecting the spraying uniformity;

[0007] When wrinkles and depressions appear on the outer wall of the pipeline under the same driving pressure, the same fluid equivalent and within the same unit time, an instantaneous pressure difference phenomenon occurs. Specifically, the instantaneous pressure difference causes changes in the water outlet speed and flow rate of the sprinkler, resulting in a concentration difference in the spraying before and after the sprinkler.

[0043] Preferably, water distribution pipes are evenly inserted and distributed at one end of the water tank close to the water and fertilizer tank, and the ends of the water distribution pipes close to the water and fertilizer tank are snap-fitted and installed with the water pipes. A pipe orifice frame that is snap-fitted and slidably connected to the hanging plate is snap-fitted and installed on the outer wall of the end of the water distribution pipe close to the water and fertilizer tank. A spray gun head is inserted and installed at one end of the water pipe away from the pipe orifice frame.

[0044] Preferably, water holes communicating with flexible brushes are evenly distributed on the inner wall of the cleaning ring, and there is an intersection between one end of the flexible brush close to the axis of the water and fertilizer tank and the water pipe. The axial length of the water and fertilizer tank is greater than the vertical distance between the two pipe joints. The inner diameter of the crescent ring is equal to the outer diameter of the water pipe. The inner diameter of the conical ring is tangent to the outer diameter of the water pipe. The vertical distance between the semi-sphere and the axis of the water and fertilizer tank is greater than the vertical distance between the ear seat or the support seat and the axis of the water and fertilizer tank.

[0045] A method for shaping the outer end hose of a water and fertilizer integration machine, using the above-mentioned irrigation and spraying device for agricultural breeding to provide shaping. The specific steps are as follows:

[0046] S1: First, close the communication channel between the water distribution pipe and the water pipe through the ball valve, and make there be a specified equivalent of fluid inside the water pipe. Thereafter, use the electric clamping jaws moving towards each other to limit the position of one end pipe joint, and control the movement of the other end pipe joint through the pipe orifice frame to drag and straighten the water pipe;

[0047] S2: Then rotate the wall ring control panel by a specified angle or number of turns. During this process, a certain degree of relative movement occurs between the panel and the semi-sphere until the corner post contacts the outer wall of the water pipe under the extrusion of the panel, and a local area of the outer wall of the water pipe sinks towards the axis by a specified distance. Thereafter, synchronously control the corner post through the corner ring to drive the corner ball to move towards the end close to the spray gun head until the corner ball close to one end of the barrel ring contacts the pipe joint (spray gun head end);

[0048] Prior to this, through the relative movement between the cleaning ring and the water pipe, during the movement of the cleaning ring, the impurities existing on the outer wall of the water pipe are scraped, rinsed and cleaned by the interaction between the flexible brush and the outer wall of the water pipe. At the same time, the conical ring is used to increase the space margin between the flexible brush and the corner ring, reducing the phenomenon that impurities splash to the outer wall of the water pipe on the corner ring side under the action of running water flushing, thus avoiding secondary pollution.

[0049] S3: Finally, through the rigid contact between the corner ball and the water pipe, a reverse acting force is applied to the crescent ring by the fluid near the cylinder ring end inside the water pipe, causing the outer wall of the water pipe to contact the inner wall of the crescent ring. At the same time, water mist is filled between the crescent ring and the filter plate through the angle valve. On the one hand, pre-wetting is provided to the outer wall of the water pipe, cooling the outer wall of the water pipe to a certain extent to form a temperature difference, enhancing the maintenance of the shaping of the outer wall of the water pipe. On the other hand, by filling the water mist between the crescent ring and the outer wall of the water pipe, a water film is formed between the two, filling the unevenness between the contact surfaces of the two, increasing the actual contact area, and improving the contact strength.

[0050] Finally, the gas existing between the crescent ring and the outer wall of the water pipe is instantaneously directed to the outside through the air valve, forming a low-pressure area between the crescent ring and the outer wall of the water pipe, ensuring the contact state between the outer wall of the water pipe and the inner wall of the crescent ring, which helps to improve the repair effect on the concave or wrinkled areas of the outer wall of the water pipe.

[0051] The present invention has the following beneficial effects:

[0052] 1. Through the contact between the positive electrode ring and the touch pressure sensor, the present invention realizes the positive feedback of the interaction degree between the corner column and the panel. That is, through the interaction between the panel and the semi-moon ball, under the linkage guiding action of the corner ring and the orifice ring, the corner ball drives different degrees of extrusion on the outer wall of the water pipe, until under the extrusion action of the corner ball on the water pipe, the fluid inside the water pipe is controlled to apply a reverse acting force to the outer wall of the water pipe in the area far from the corner ring end. And through the contact state between the positive electrode ring and the touch pressure sensor, the rotation angle or number of turns of the wall ring is judged, and the interaction degree between the closed-loop semi-moon ball and the outer wall of the water pipe is determined, avoiding excessive contact between the panel and the semi-moon ball, and improving the service life of the water pipe.

[0053] During this process, through the alternating operation between the air valve and the angle valve, the gas between the crescent ring and the outer wall of the water pipe is discharged, the "tiny" gap existing between the crescent ring and the outer wall of the water pipe is filled, the contact rigidity between the inner wall of the crescent and the outer wall of the water pipe is improved, and the outer wall of the water pipe is pre-wetted to form a temperature difference, enhancing the shaping effect. First, the shape of the outer wall of the water pipe is "destroyed" to break the non-linear state of the concave or wrinkled areas on the traditional outer wall of the water pipe, that is, the concave and wrinkled areas on the outer wall of the water pipe are linearly unified. Then, the concave areas on the outer wall of the water pipe are regularly "repaired", reducing the repair difficulty of the concave and wrinkled areas on the outer wall of the water pipe, improving the repair effect, improving the instantaneous pressure difference phenomenon existing during the process of the water pipe transporting fluid, preventing the retention of the water and fertilizer mixture, reducing the local accumulation of the water and fertilizer mixture, enhancing the concentration uniformity of the water and fertilizer mixture inside the water pipe under the same driving pressure and the same fluid equivalent per unit time, and to a certain extent, reducing the uneven spraying of the water and fertilizer mixture by the nozzle.

[0077] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0078] It should be noted that the terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation.

[0079] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0080] Refer to Figure 1 、 Figure 2 and Figure 7 It can be known that an irrigation spraying device and a using method for agricultural breeding include a water and fertilizer bin 1. One end inside the water and fertilizer bin 1 is provided with a pressure unit 2. One end of the pressure unit 2 is provided with a shaping unit 3. A peripheral unit 4 is arranged in the space on one side outside the water and fertilizer bin 1;

[0081] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 It can be known that the peripheral unit 4 includes: an electric gripper 41, which is clamped and installed on the outer wall of the water and fertilizer bin 1 near one end of the cleaning ring 221 through an electric telescopic rod, and the number of electric grippers 41 is two, which are symmetrically distributed; a water pipe 42, which is coaxially arranged at the axis of the water and fertilizer bin 1; pipe connectors 43, which are symmetrically clamped and installed at both ends of the water pipe 42 through flange plates; in addition, the electric gripper 41 is clamped and installed in cooperation with the outer wall of the pipe connector 43; a ball valve 44, which is rotatably installed inside the pipe connector 43; brackets 45, the number of which is two, and which are symmetrically clamped and installed on the outer wall of the water and fertilizer bin 1; a hanging plate 46, which is clamped and installed at the middle position of the end face on the side of the two brackets 45 away from the water and fertilizer bin 1; a wall plate 47, which is clamped and installed at the end of the hanging plate 46 away from the water and fertilizer bin 1; a water fertilizer machine 48, which is arranged near one end of the water and fertilizer bin 1 close to the wall plate 47, and the outer wall of the housing of the water fertilizer machine 48 is clamped and installed in cooperation with the wall plate 47; a water tank 49, which is built inside the water fertilizer machine 48;

[0082] Refer to Figure 1 It can be known that the water tank 49 is evenly inserted and distributed with water distribution pipes 411 near one end of the water and fertilizer bin 1, and the ends of the water distribution pipes 411 near the water and fertilizer bin 1 are clamped and installed in cooperation with the water pipe 42. A pipe orifice frame 412 that is slidably clamped and installed in cooperation with the hanging plate 46 is clamped and installed on the outer wall of the end of the water distribution pipe 411 near the water and fertilizer bin 1. A spray gun head 413 is inserted and installed at one end of the water pipe 42 away from the pipe orifice frame 412.

[0083] Before the shaping unit 3 shapes the outer wall of the water pipe 42, the adjustment process of the horizontal state of the water pipe 42:

[0084] First, through the opposite movement between the electric grippers 41 (refer to the telescopic principle of the electric telescopic rod. In specific implementation, for the oppositely distributed electric grippers 41, the telescopic end gripper can move towards the pipe joint 43), the pipe joint 43 (the end of the spray gun head 413) is clamped and limited. Then, the electric gripper 41 controls the pipe joint 43 to move a specified distance towards the spray gun head 413 (in specific implementation, the current state of the hose can be calculated externally to serve as the single-displacement parameter of the electric gripper 41). Specifically, the electric gripper 41 can be driven by the electric telescopic rod to move along the axis direction of the water and fertilizer tank 1;

[0085] Next, the pipe orifice holder 412 drives the other end pipe joint 43. Under the supporting and guiding action of the hanging plate 46, it cooperates with the aforementioned electric gripper 41 to traction and drag the water pipe 42 until the water pipe 42 inside the water and fertilizer tank 1 is in a horizontal state (with the gravity direction as the reference). In specific implementation, the electric slider can be used to drive the pipe orifice holder 412 to move;

[0086] Finally, when the traction of the water pipe 42 to the horizontal state is completed, the ball valve 44 blocks the communication channel between the water and fertilizer mixture inside the water pipe 42 in the area covered by the water and fertilizer tank 1 and the water tank 49 (and in specific implementation, the equivalent independent variable of the water and fertilizer mixture flowing through the unit cross-section per unit time into the water pipe 42 between the two ball valves 44 can be controlled to avoid the inconsistency of the equivalent before and after the water and fertilizer mixture inside the water pipe 42 in the area covered by the water and fertilizer tank 1, that is, to reduce the influence of the unnecessary external independent variable on the dependent variable (the extrusion between the unit volume of the water and fertilizer mixture and the inner wall of the water pipe 42));

[0087] Simple process of the water and fertilizer mixture flowing to the spray gun head 413:

[0088] The water and fertilizer mixture inside the water tank 49 is quantitatively transported to the water pipe 42 through the built-in water pump via the sub-water pipe 411. After that, the water and fertilizer mixture is evenly guided to the spray gun head 413 through the water pipe 42. Finally, the evenly mixed water and fertilizer mixture is sprayed onto the area of the seedlings or seeds to be irrigated through the spray gun head 413 (in specific implementation, the fertilizer inside the fertilizer tank can be quantitatively transported to the mixer through the fertilizer applicator, and then the quantitative water source is pumped into the mixer by the water pump. After being mixed by the mixer and filtered by the filtration system, the water and fertilizer mixture is pumped into the specified spray gun head 413 by the water pump);

[0089] Bracket 45, hanging plate 46 and wall panel 47: The wall panel 47 provides a stable installation environment for the hanging plate 46. At the same time, through the rigid connection between the hanging plate 46 and the bracket 45, the operation stability and safety of the aforementioned pressure unit 2 and shaping unit 3 are strengthened (in specific implementation, the relative positions of the hanging plate 46 and the bracket 45 can be adjusted accordingly according to the actual operation area of the water pipe 42, that is, there is installation flexibility between the hanging plate 46 and the bracket 45 and the water and fertilizer tank 1).

[0090] Referring to Figure 5 、 Figure 7 and Figure 9 it can be seen that the pressure unit 2 includes: an angle ring 21, coaxially arranged at the middle position inside the water and fertilizer bin 1; a mouth ring 22, coaxially arranged outside the angle ring 21; at least one fascia plate 23, which is snap-fitted between the angle ring 21 and the mouth ring 22; angle columns 24, three in a group, at least four groups, and circumferentially slidably snap-fitted between the angle ring 21 and the mouth ring 22 in the form of groups; an angle ball 25, snap-fitted at one end of the angle column 24 close to the axis of the water and fertilizer bin 1;

[0091] a half moon ball 26, snap-fitted at one end of the angle column 24 away from the angle ball 25; an interface valve 27, inserted and installed at the middle position of the outer wall of the angle ring 21; gaskets 28, symmetrically arranged on the outer wall of the angle column 24; in addition, the gasket 28 at one end away from the axis of the water and fertilizer bin 1 is snap-fitted and installed with the outer wall of the angle column 24, and the other gasket 28 is snap-fitted and installed with the end face on the side away from the axis of the water and fertilizer bin 1 of the mouth ring 22; a return spring 29, snap-fitted between the two gaskets 28;

[0092] Referring to Figure 5 、 Figure 6 and Figure 14 it can be seen that a wall ring 211 is rotatably fitted and installed at the middle position of the inner wall of the water and fertilizer bin 1. The inner wall of the wall ring 211 is circumferentially and evenly snap-fitted with panels 212, and the cross-sectional shape of the panel 212 is wavy. The outer wall of the angle ring 21 is symmetrically snap-fitted with ear seats 213. A strip bar 214 is slidably snap-fitted at the middle position of one end of the ear seat 213 away from the angle ring 21. The two ends of the strip bar 214 are snap-fitted and installed with a position ring 215 that is rotatably fitted and installed with the axial inner wall of the water and fertilizer bin 1. The middle one of the angle balls 25 in the same group of angle balls 25 has a heating ring 216 snap-fitted inside its inner wall;

[0093] Referring to Figure 6 、 Figure 7 and Figure 8 it can be seen that a cleaning ring 221 is rotatably fitted and installed at one end of the angle ring 21. A flexible brush 222 is snap-fitted at one end of the inner wall of the cleaning ring 221 away from the angle ring 21. A ring track 223 is rotatably fitted and installed on the outer wall of the angle ring 21 close to the cleaning ring 221. A support rod 224 that is snap-fitted with the ring track 223 is snap-fitted at the middle position of one side outer wall of the cleaning ring 221. A conical ring 225 is snap-fitted at one end of the inner wall of the cleaning ring 221 close to the angle ring 21. A water valve 226 is snap-fitted at the middle position of the end face on the side of the cleaning ring 221 away from the angle ring 21;

[0094] The inner wall of the cleaning ring 221 is evenly distributed with water holes communicating with the flexible brush 222, and there is an intersection between one end of the flexible brush 222 close to the axis of the water and fertilizer tank 1 and the water pipe 42. The axial length of the water and fertilizer tank 1 is greater than the vertical distance between the two pipe joints 43, and the inner diameter of the conical ring 225 is tangent to the outer diameter of the water pipe 42.

[0095] The cleaning process of the outer wall impurities of the water pipe 42 by the flexible brush 222:

[0096] First, the angle ring 21 controls the cleaning ring 221 to move along the axis of the water and fertilizer tank 1, driving the flexible brush 222 to move towards the spray gun head 413.

[0097] Next, the water valve 226 and the external water source storage are connected through an external hose, and then, the clean water source stored in the external water source storage is pumped into the cleaning ring 221 by an external water pump.

[0098] During this process, the fluid continuously penetrates and interacts with the water holes on the inner wall of the cleaning ring 221 under the action of gravity until the fluid is fully in contact with and wets the flexible brush 222 (the flexible bristles have a certain toughness and can better fit the irregular surface of the outer wall of the water pipe 42 during actual use, increasing the contact area with impurities and improving the cleaning effect; in addition, the fluid can reduce the adhesion between the impurities and the outer wall of the water pipe 42, ensuring the cleaning ability of the flexible brush 222). After that, the wetted flexible brush 222 continuously makes a horizontal relative movement with the outer wall of the water pipe 42 under the control of the angle ring 21.

[0099] Finally, the ring rail 223 controls the support rod 224 to drive the cleaning ring 221 to continuously rotate under the support of the angle ring 21. In this way, a circumferential relative movement occurs between the flexible brush 222 and the outer wall of the water pipe 42, creating a new relative movement state and enhancing the interaction degree between the flexible brush 222 and the impurities on the outer wall of the water pipe 42 (reducing the time adaptability generated by a single relative movement form, changing the movement form of the impurities between the flexible brush 222 and the outer wall of the water pipe 42, and enhancing the cleaning effect). During specific implementation, the support rod 224 can be driven to rotate by an electric slider.

[0100] At the same time, the conical ring 225 increases the space margin between the flexible brush 222 and the angle ring 21, reducing the sputtering phenomenon of impurities towards the outer wall of the water pipe 42 on the side of the angle ring 21 under the action of flowing water flushing and causing secondary pollution.

[0101] The "destructive" unified regularization process of the non-linear, discontinuous depressions and folds on the outer wall of the water pipe 42 by the corner ball 25:

[0102] The fluid equivalent in the water pipe 42 between the two ball valves 44 in the closed state is certain:

[0103] First, the wall ring 211 controls the panel 212 to rotate a specified angle or number of circles (in specific implementation, the wall ring 211 can be driven by an electric slider to stably rotate along the inner wall of the water and fertilizer bin 1). During this process, the degree of interaction between the panel 212 and the half moon 26 gradually deepens, until the corner column 24 drives the corner ball 25 to move toward the axis of the water and fertilizer bin 1 under the joint support and guidance of the corner ring 21 and the mouth ring 22 (the fascia plate 23 provides an installation environment for the mouth ring 22 and the corner ring 21 to enhance the movement stability of the corner column 24), and the corner ball 25 squeezes the outer wall of the water pipe 42 to a certain extent;

[0104] Next, under the guidance and support of the bar 214, the ear seat 213 synchronously controls the corner ring 21 to drive the corner ball 25 to move a specified displacement along the axis direction of the water-fertilizer bin 1. During the movement, the corner balls 25 in different areas perform extrusion shaping on the non-continuous, nonlinear concave and wrinkled areas on the outer wall of the water pipe 42, and the front end (current movement direction) corner ball 25 performs pre-extrusion "opening" on the outer wall of the water pipe 42, and the middle corner ball 25 and the rear end corner ball 25 perform supplementary extrusion shaping on the outer wall of the water pipe 42 (at the current angle, a uniform semicircular groove is squeezed out on the outer wall of the water pipe 42). In specific implementation, the ear seat 213 can be driven to move by an electric slider;

[0105] Finally, the heating ring 216 located inside the corner ball 25 in the middle area (in specific implementation, the heating ring 216 can be electrically connected to the external heating device through an electric wire) provides heat to the corner ball 25, and the corner ball 25 transfers heat to the outer wall of the water pipe 42, thereby achieving extrusion and shaping of the outer wall of the water pipe 42 while changing the local temperature difference of the outer wall of the water pipe 42, reducing the difficulty of extrusion and shaping between the corner ball 25 and the outer wall of the water pipe 42, and creating a local temperature difference environment for the outer wall of the water pipe 42;

[0106] At the same time, when the corner ball 25 interacts with the outer wall of the water pipe 42, the fluid inside the water pipe 42 flows to other areas of the water pipe 42 under the Pascal principle (according to the continuity principle, in the stable flow of incompressible fluid, the flow rate of the fluid through any cross section remains unchanged. In order to keep the flow rate unchanged, the flow velocity of the fluid in the current squeezed area increases, thereby forming a flow from the squeezed area to other areas), until the outer wall of the water pipe 42 conflicts with the shaping unit 3 component, and the outer wall of the water pipe 42 is tangent to the inner wall of the cone ring 225 (the closed-loop flexible brush 222 cleans the outer wall of the water pipe 42, that is, further avoids secondary coverage and pollution of the aforementioned cleaned area by sewage during the cleaning process of the flexible brush 222);

[0107] Purpose of keeping the outer wall of the water pipe 42 clean: Reduce the rigid contact between the corner ball 25 and the impurities on the outer wall of the water pipe 42, avoid the damage of the material of the water pipe 42 caused by the rigid contact, and improve the service life of the water pipe 42; At the same time, avoid the influence of external rigid impurities on the movement stability of the corner ball 25 (affecting the connection accuracy between the corner post 24, the port ring 22 and the corner ring 21);

[0108] How to achieve the "destructive" unified regular shaping of the outer walls of different regions of the water pipe 42:

[0109] By controlling the rotation of the bar 214 through the position ring 215, it is urged that the ear seat 213, under the carrying action of the corner ring 21, synchronously drives the corner ring 21 to rotate a certain angle (ensuring that the corner ball 25 can perform "destructive" shaping of uniform specifications on the discontinuous, non-linear concave and folded areas existing on the outer wall of the water pipe 42). And in this process, to avoid the rigid contact between the corner ball 25 and the outer wall of the water pipe 42, resulting in the limitation of the rotation of the corner ring 21 due to the contact between the two, specifically in implementation, the wall ring 211 can be synchronously controlled to rotate the same angle (in the same direction);

[0110] Interface valve 27: Connect the external air pump through the interface valve 27 and the external hose to ensure that there is a certain amount of gas in the area covered by the corner ring 21 during the movement of the corner ring 21, and further reduce the existence of impurities on the outer wall of the water pipe 42 in the area covered by the corner ring 21.

[0111] Refer to Figure 7 、 Figure 10 、 Figure 11 and Figure 12 It can be known that the shaping unit 3 includes: a cylinder ring 31, coaxially arranged at one end of the corner ring 21 away from the cleaning ring 221; a ring 32, snap-fitted on the end face of the cylinder ring 31 away from the corner ring 21; a layer ring 33, snap-fitted on the end face of the cylinder ring 31 away from the corner ring 21, and the diameter of the layer ring 33 is smaller than the diameter of the ring 32; two supports 34 as a group, symmetrically snap-fitted at the middle position of the outer wall of the cylinder ring 31; in addition, the support 34 and the bar 214 are slidingly snap-fitted;

[0112] At least four columns 35, circumferentially slidingly snap-fitted between the ring 32 and the layer ring 33; a base 36, snap-fitted on the inner wall of the cylinder ring 31, and the position and quantity of the base 36 correspond to those of the columns 35 one by one; a positive electrode ring 37, snap-fitted at one end of the column 35 away from the axis of the cylinder ring 31; a touch sensor 38, snap-fitted at the middle position of the base 36 close to the column 35; a telescopic spring 39, sleeved on the outer wall of the column 35, and the telescopic spring 39 is located between the ring 32 and the layer ring 33;

[0113] Refer to Figure 10 、 Figure 11 and Figure 12It can be seen that a crescent ring 311 is snap-fitted and installed at one end of the column 35 away from the base 36. A filter plate 312 having the same cross-sectional shape as the crescent ring 311 is snap-fitted and installed at one end of the crescent ring 311 away from the column 35. The surface of the filter plate 312 is evenly distributed with filter holes. An air valve 313 is inserted and installed at the middle position of one end of the end face of the crescent ring 311 close to the column 35. A corner valve 314 is inserted and installed at the middle position of the other end of the end face of the crescent ring 311 close to the column 35. Pressure sensors 315 are snap-fitted and installed at both ends of the crescent ring 311. A rubber pad 316 is sleeved and fitted on the end face of the pressure sensor 315 on the side away from the axis of the column 35;

[0114] Referring to Figure 7 , Figure 11 and Figure 13 It can be seen that a sealing chamber 321 is rotatably fitted and installed at one end of the cylindrical ring 31 away from the corner ring 21. A double-sided ring 322 is snap-fitted and installed on the end face of the sealing chamber 321 away from the corner ring 21. At least four spring rods 323 are slidably snap-fitted between the double-sided rings 322. An electrode plate 324 is snap-fitted and installed at one end of the spring rod 323 away from the axis of the sealing chamber 321. Electrode rings 325 corresponding to the electrode plates 324 one by one are snap-fitted and installed on the inner wall of the sealing chamber 321. An electric circular rail 326 is rotatably fitted and installed on the outer wall of the cylindrical ring 31 at one end away from the corner ring 21. A guiding column 327 snap-fitted with the electric circular rail 326 is snap-fitted and installed at the middle position of one outer wall of the sealing chamber 321. A detection ball 328 is snap-fitted and installed at one end of the spring rod 323 close to the axis of the sealing chamber 321.

[0115] The positive feedback closed-loop process between the state of the crescent ring 311 in contact with the outer wall of the water pipe 42 and the state of the corner ball 25 pressing against the outer wall of the water pipe 42:

[0116] Or the repair process of the area where the crescent ring 311 presses the aforementioned corner ball 25:

[0117] When the corner ball 25 maintains a certain mutual extrusion with the outer wall of the water pipe 42:

[0118] First of all, under the reverse acting force of the crescent ring 311 on the column 35 (the fluid inside the water pipe 42 at one end away from the cleaning ring 221 exerts a reverse acting force on the outer wall of the water pipe 42 under the extrusion of the corner ball 25. The outer wall of the current area of the water pipe 42 is in contact with the inner wall of the crescent ring 311 and maintains a certain mutual acting force, and at this time the outer wall of the water pipe 42 is in a relatively "expanded" state), the positive electrode ring 37 is controlled to move in a direction away from the axis of the cylindrical ring 31 until the positive electrode ring 37 comes into contact with the touch pressure sensor 38. In specific implementation, the layer ring 33 and the ring 32 can provide stable support for the moving column 35, which helps to improve the contact accuracy between the positive electrode ring 37 and the touch pressure sensor 38;

[0119] Next, connect an external water source storage through the angle valve 314 and an external hose, and gradually fill the space between the crescent ring 311 and the filter plate 312 with the external water source until the external water source penetrates through the filter holes on the surface of the filter plate 312 to the outer wall of the water pipe 42 in contact therewith. On the one hand, provide pre-wetting to the outer wall of the water pipe 42, cool the outer wall of the water pipe 42 to a certain extent, and form a temperature difference (corresponding to the temperature difference environment created by the heating ball mentioned above), so as to improve the maintenance of the shaping of the outer wall of the water pipe 42. On the other hand, fill the space between the crescent ring 311 and the outer wall of the water pipe 42 with water mist to form a water film between the two, fill the unevenness between the contact surfaces of the two, increase the actual contact area, improve the contact strength, ensure the fitting degree between the outer wall of the water pipe 42 and the inner wall of the crescent ring 311, and improve the final forming effect of the outer wall of the water pipe 42;

[0120] After that, referring to the above-mentioned filling of water mist into the intersection of the crescent ring 311 and the water pipe 42, similarly, the gas in the aforementioned intersection area can be instantaneously evacuated through the external hose and the air pump to form a low-pressure area in the aforementioned area, further improving the contact state between the crescent ring 311 and the outer wall of the water pipe 42;

[0121] Finally, under the action of the restoring force of the telescopic spring 39 of the column 35 (when the fluid inside the water pipe 42 tends to be stable, the outer wall of the water pipe 42 in the aforementioned "expanded" state gradually tends to be stable, that is, compared with the normal state), synchronously control the positive electrode ring 37 to move towards the direction close to the axis of the cylinder ring 31 until the positive electrode ring 37 is separated from the touch pressure sensor 38. At this time, the rubber pads 316 at the adjacent ends of the four circumferentially distributed crescent rings 311 are in contact (in specific implementation, the limit movement state of the circumferentially distributed crescent rings 311 can be judged through the feedback of the pressure sensor 315). At the same time, through the disconnection between the positive electrode ring 37 and the touch pressure sensor 38, it is used as the signal for the rotation stop of the wall ring 211 to avoid excessive contact between the panel 212 and the semi-sphere 26;

[0122] The detection process of the flatness of the outer wall of the water pipe 42 in the shaping state by the detection ball 328:

[0123] Judge the contact state between the detection ball 328 and the outer wall of the water pipe 42 under the same axis through the contact state between all the area electrode plates 324 and the electrode ring 325 (release the freedom degree of the detection ball 328 through the elastic variable of the spring rod 323 itself, and at the same time provide stable moving support for the spring rod 323 through the double-sided ring 322), so as to judge the smoothness of the outer wall of the water pipe 42. And in specific implementation, the rotation of the electric circular rail 326 can be used to control the guiding column 327 to drive the sealing chamber 321 to rotate, so as to adjust the contact detection between the detection ball 328 and different area end faces of the water pipe 42.

[0124] An irrigation spraying device for agricultural breeding provided by the present invention and its usage method are as follows: First step: Firstly, close the communication channel between the sub-water pipe 411 and the water pipe 42 through the ball valve 44, and make there be a specified equivalent amount of fluid inside the water pipe 42. Thereafter, limit the position of one end pipe joint 43 through the oppositely moving electric clamping jaws 41, and control the movement of the other end pipe joint 43 through the pipe orifice bracket 412 to drag and straighten the water pipe 42;

[0125] Second step: Then rotate the control panel 212 of the wall ring 211 by a specified angle or number of turns. During this process, a certain degree of relative movement occurs between the panel 212 and the semi-moon ball 26 until the corner post 24 contacts the outer wall of the water pipe 42 under the extrusion of the panel 212, and a local area of the outer wall of the water pipe 42 sinks towards the axis direction by a specified distance. After that, synchronously control the corner post 24 through the corner ring 21 to drive the corner ball 25 to move towards the end close to the spray gun head 413 until the corner ball 25 at the end close to the barrel ring 31 contacts the pipe joint 43 (the spray gun head 413 end);

[0126] Before this, through the relative movement between the cleaning ring 221 and the water pipe 42, during the movement of the cleaning ring 221, through the interaction between the flexible brush 222 and the outer wall of the water pipe 42, scrape, wash and clean the impurities existing on the outer wall of the water pipe 42. At the same time, increase the space margin between the flexible brush 222 and the corner ring 21 through the tapered ring 225 to reduce the phenomenon that impurities splash towards the outer wall of the water pipe 42 on the side of the corner ring 21 under the action of flowing water flushing, causing secondary pollution;

[0127] Third step: Finally, through the rigid contact between the corner ball 25 and the water pipe 42, cause the fluid at the end close to the barrel ring 31 inside the water pipe 42 to exert a reverse force on the crescent ring 311, so that the outer wall of the water pipe 42 abuts against the inner wall of the crescent ring 311. At the same time, fill the crescent ring 311 and the filter plate 312 with water mist through the angle valve 314. On the one hand, provide pre-wetting for the outer wall of the water pipe 42, cool the outer wall of the water pipe 42 to a certain extent to form a temperature difference, and improve the maintenance of the shaping of the outer wall of the water pipe 42; On the other hand, fill the crescent ring 311 and the outer wall of the water pipe 42 with water mist to form a water film between the two, fill the unevenness between the contact surfaces of the two, increase the actual contact area, and improve the contact strength;

[0128] Finally, instantaneously guide the gas existing between the crescent ring 311 and the outer wall of the water pipe 42 to the outside through the air valve 313 to form a low-pressure area between the crescent ring 311 and the outer wall of the water pipe 42, ensuring the abutting state between the outer wall of the water pipe 42 and the inner wall of the crescent ring 311, which helps to improve the repair effect on the concave or wrinkled areas of the outer wall of the water pipe 42.
