[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. A combined self-adjusting component is provided. The lifting screw rod drives the double-hole socket block to move along the positioning special-shaped frame, and cooperates with the sliding positioning sleeve, the support spring and the T-shaped clamping sleeve to adjust the heights of the bidirectional special-shaped pipe and the double-drawing special-shaped pipe. Then, the protective hose serves as a relay for water inlet and outlet between the branch diversion pipe and the bidirectional special-shaped pipe, realizing the adjustment and correction of the pipeline position according to the type and growth cycle of plants, ensuring the accuracy of water outlet alignment, and keeping the water outlet holes away from the ground to avoid soil blocking the pipeline, ensuring the stability of equipment use. By the external water pressure pushing the float push block, the float push block drives the conical pressing frame and the guiding support rod to move, so that the conical pressing frame is separated from the fitting sealing ring, and cooperates with the water depth detector, the extraction fixed pipe and the bidirectional pump, and at the same time cooperates with the dripping holes on the side end of the bidirectional special-shaped pipe, realizing the extraction of accumulated water in the field and controlling the water volume in the field to avoid the influence of accumulated water on plant growth;

[0033] The downward pressure spring drives the three-round sliding frame to be sleeved and clamped with the blocking sliding ring, and the upward spring drives the conical clamping block and the T-shaped circular plate frame to be separated from the clamping annular block and the closing limit ring, realizing that drip irrigation operation can be carried out at low water pressure, and using the water pressure to push the conical clamping block to move to the clamping annular block, adjusting the water outlet speed according to the water pressure, balancing the water outlet speeds at positions far from and close to the water supply position, ensuring uniform water outlet. Then, by the water pressure pushing the three-round sliding frame to be separated from the blocking sliding ring and the conical clamping block to move to the clamping annular block for clamping, and cooperating with the threaded fixed pipe and the high-pressure spray water at the top of the fixed nozzle frame, using the water pressure to change the water outlet position inside the pipeline, thus realizing the switching of different fertilization and watering states, realizing the adjustment of the equipment according to the growth state and type of plants, improving the applicable range of the equipment, and ensuring the accuracy of fertilization and watering;

[0034] Multiple groups of adjustment devices are used to change the position of the pipeline and the height of the sprinkler head according to the type and growth cycle of plants, and in combination with the water pressure, change the water outlet position of the pipeline and the water inlet direction of the pipeline, effectively solving the problems in the prior art that the pipeline position and the water outlet position cannot be adjusted and the pipeline is easily blocked, thereby realizing targeted fertilization and watering, and can be self-adjusted by using internal facilities without excessive operation intervention by staff, improving the automation of the equipment, reducing the cumbersome operation of the staff, and improving the work efficiency.

[0035] 2. A blocking and circulating component is provided. The backflow injection pipe, the connecting and fixing pipe, the liquid discharge fixing pipe and the slag discharge fixing pipe are controlled by a processing valve to achieve the control of water inlet and outlet. The storage cage is fixed to the inner side of the mixing and processing tank by clamping the storage cage and the threaded closing ring through threads. It is injected into the inner net closing cover and the side end of the storage cage through a reflux pump, a reflux injection pipe, a connecting and fixing pipe and a limit pipe support. The water-soluble fertilizer in the storage cage is continuously flushed and dissolved by high-pressure water flow to achieve full mixing of water and fertilizer. And the cage is used for scouring and mixing to increase the contact area, accelerate the mixing speed while reducing the residue of particulate matter, ensure the uniformity of mixing, and reduce the waiting time for operation;

[0036] The rainwater flowing back through the extraction and fixing pipe is filtered and intercepted by a filter plate to realize the recycling of rainwater. In combination with the slag discharge fixing pipe, the accumulated impurities are flushed by high-pressure water flow to realize self-cleaning of slag, ensuring the stability of the recovery and purification treatment of rainwater, improving the service life of the equipment, and reducing the maintenance complexity. The impurities contained in the water and fertilizer are combined and intercepted by an intercepting sinking cylinder and a multi-ring blocking cylinder to realize the filtering treatment of water and fertilizer, reducing the entry of impurities into the pipeline to block the pipeline and ensuring the stable operation. Through the mutual cooperation of a reflux intercepting component, a flushing and dissolving component and a multi-stage intercepting component, the recycling of rainwater is realized, and the dissolution speed of the fertilizer can be effectively accelerated, reducing the entry of impurities into the pipeline and affecting the normal operation of the equipment, effectively improving the stability of the equipment, extending the service life of the equipment, and reducing the waste of resources.

[0037] In summary, through the mutual cooperation of the combined self-adjusting component and the blocking and circulating component, multiple groups of intercepting mechanisms are used to intercept and process the impurities in the water and fertilizer, avoiding pipeline blockage and affecting the service life. And through the two-way water inlet and outlet operation, the water exchange between multiple devices and the recycling of rainwater are realized, improving the linkage of the equipment. Through the mutual cooperation of multiple components, the service life of the equipment is extended and the waste of resources is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] The working principle and usage process of the present invention: When laying the water and fertilizer integration device, the staff place the storage fixed box 205, the centralized fixed box 208, and the mixing treatment box 301 at the set positions, then fix the overall fixed pipe 1 to the ground according to the actual positions and spacings in the field, and then adjust the spacing of the branch diversion pipes 201 according to the spacing of the planted plants. After the fixation is completed, the protective hose 202 is sleeved on the side end of the branch diversion pipe 201. After the fixation is completed, the positioning special-shaped frame 215 is fixed to the field, and then according to the number of double-drawing special-shaped pipes 213 and double-way special-shaped pipes 211, the T-shaped clamping sleeve 219 is fixed to the field. After the fixation is completed, the double-hole socket block 214 is sleeved on the side end of the double-way special-shaped pipe 211. Multiple groups of double-way special-shaped pipes 211 are fixedly connected through multiple adapters, and the double-way special-shaped pipe 211 is fixedly connected to the protective hose 202 by using an adapter. Then, the double-drawing special-shaped pipe 213 and the double-way special-shaped pipe 211 are connected to each other through the threaded tee 212, so as to realize the connection and fixation of multiple groups of pipes. After the pipe fixation is completed, the double-hole socket block 214 is driven by the lifting screw 216 to slide along the positioning special-shaped frame 215, so as to drive the sliding positioning sleeve 217 to move up and down along the T-shaped clamping sleeve 219 in cooperation with the support spring 218. It is beneficial for the lifting screw 216 to drive the double-hole socket block 214 and the support spring 218 to drive the sliding positioning sleeve 217 to drive the double-way special-shaped pipe 211 and the double-drawing special-shaped pipe 213 to adjust the pipe position and pipe height according to the actual plants and terrain, so as to effectively change the device position in different fields, be applicable to a variety of different fields and plants. After the pipe installation is completed, the threaded fixed pipe 240 is fixedly connected to the fixed sprinkler head frame 241. After the fixation is completed, it drives the clamping sliding block 242 to rotate and displace along the porous circular frame 239. After moving to the required position, the lifting spring 243 drives the lifting insertion block 244 to slide up along the clamping sliding block 242, and the clamping connection between the clamping sliding block 242 and the porous circular frame 239 is realized by using the lifting insertion block 244, so as to realize the positioning restriction of the fixed sprinkler head frame 241, thereby changing the spraying state according to the height of the plants, the position of the leaf surface, and the state of the leaf surface, realizing targeted treatment, reducing the waste of water and fertilizer, and fixedly clamping the interception fixed barrel 221 by using the threaded tee 212;

[0074] After the pipeline is fixedly installed, open the water inlet storage pipe 315 through the treatment valve 318, inject water into the inner sides of the storage fixing box 205 and the centralized fixing box 208, place the water-soluble fertilizer inside the storage wire cage 303, insert the storage wire cage 303 into the inner side of the threaded closing ring 302, and fixedly connect the storage wire cage 303 and the threaded closing ring 302 by using threads. Fix and seal the threaded closing ring 302 through the inner network closing cover 304, fix the limit pipe support 305 to the top end of the inner network closing cover 304 through the adapter. After the fixation is completed, extract the water located in the centralized fixing box 208 through the reflux pump 307 and the reflux injection pipe 306. At this time, close the treatment valve 318 located at the position of the reflux injection pipe 306, open the treatment valve 318 located at the position of the connection fixing pipe 308, and inject the water along the reflux injection pipe 306, the connection fixing pipe 308 and the limit pipe support 305 to the positions of the inner network closing cover 304 and the storage wire cage 303. Continuously wash and dissolve the water-soluble fertilizer in the storage wire cage 303 through the high-pressure water flow. When mixing the water and fertilizer, test the concentration of the fertilizer through the concentration detector 310, understand the actual fertilizer concentration in real time, and thus adjust the fertilizer output speed according to the fertilizer concentration to ensure the stability of the mixing and improve the uniformity and accuracy of the fertilizer supply;

[0075] After the fertilizer mixing is completed and the water in the storage fixing tank 205 and the centralized fixing tank 208 is stored to the required amount, the water at the position of the storage fixing tank 205 is pumped by the booster pump 207 and the water inlet fixing pipe 203. While pumping water, the control linkage valve 210 is opened to open the liquid injection mixing pipe 206, and the opening degree of the control linkage valve 210 is adjusted according to the concentration of the water fertilizer and the fertilizer supply speed. The water fertilizer flows into the inner sides of the double-sided special-shaped pipe 211 and the double-pumping special-shaped pipe 213 along the overall fixing pipe 1, the branch diversion pipe 201 and the protective hose 202. When the water supply is at low water pressure, at this time, the downward pressure spring 236 in the double-sided special-shaped pipe 211 drives the three-round smooth fitting frame 237 to move downward along the blocking sliding ring 238, and the three-round smooth fitting frame 237 is sleeved on the side end of the blocking sliding ring 238, realizing the multi-position fitting of the three-round smooth fitting frame 237 and the blocking sliding ring 238, and realizing the sealing treatment of the water outlet position at the top end of the double-sided special-shaped pipe 211. At the same time, the water pressure pushes the T-shaped circular plate frame 233 and the conical clamping block 231 to move downward. At this time, the upward spring 230 is slightly stretched, and the water flows through the clamping annular block 232 and the closing limit ring 234 to the position of the T-shaped circular plate frame 233 at the inner bottom of the double-sided special-shaped pipe 211. At this time, the water flow discharges along the intercepting net plate 228 and the dripping holes 235, forming slow drip irrigation, so that when directly fertilizing and watering the roots, it can be quickly operated. And when discharging water, by changing the positions of the conical clamping block 231 and the T-shaped circular plate frame 233 through the upward spring 230, the distance between the conical clamping block 231 and the clamping annular block 232 is adjusted, realizing the control of the drip irrigation speed, avoiding large drip irrigation differences in the pipes near and far from the water supply position, and balancing the flow rate and uniformity of the overall drip irrigation;

[0076] When top spraying is required, at this time, the water pressure increases, and the high-pressure water flow pushes the T-shaped circular plate frame 233 and the conical clamping block 231 to move downward. At this time, the upward spring 230 is stretched, and the conical clamping block 231 is clamped inside the clamping annular block 232, and the T-shaped circular plate frame 233 is attached to the side end of the closing limit ring 234 to seal the bottom end of the double-sided special-shaped pipe 211. At the same time, the high-pressure water flow pushes the three-round smooth fitting frame 237 to move along the blocking sliding ring 238, and the three-round smooth fitting frame 237 is separated from the blocking sliding ring 238. At this time, the downward pressure spring 236 is stretched, and the water flow flows upward along the double-sided special-shaped pipe 211. The water fertilizer is injected into the position of the fixed nozzle frame 241 through the double-sided special-shaped pipe 211 and the threaded fixing pipe 240, and is discharged outward through the fixed nozzle frame 241 to fertilize and water the leaves of the plant. The equipment inside the pipeline is controlled by the water pressure to adjust the water outlet state, so as to directly adjust the irrigation requirements of the plant, which is convenient for applying to different plants;

[0077] When supplying water at low and high pressures, the conical pressing frame 224 inside the double-drawing special-shaped pipe 213 is driven by the pressing spring 223 and is guided and supported by the guiding support rod 226. The conical pressing frame 224 is inserted and sleeved onto the side end of the fitting sealing ring 225. When there is a large amount of accumulated water in the field due to external rain, the water depth detector 220 measures the water depth. When the water storage reaches the height that endangers the plants, at this time, the water pressure pushes the floating block 227 upward. The floating block 227 drives the guiding support rod 226 to move along the double-drawing special-shaped pipe 213. At this time, the pressing spring 223 is compressed, and the conical pressing frame 224 moves along the limit fixed sliding ring 222, separating the conical pressing frame 224 from the fitting sealing ring 225. At the same time, the three-round fitting frame 237 at the position of the double-direction special-shaped pipe 211 is reset under the drive of the downward pressing spring 236, and the conical engaging block 231 is reset by the upward spring 230. The accumulated water in the field is pumped through the double-direction pump 209, the extraction fixed pipe 204, the overall fixed pipe 1, the branch diversion pipe 201, the protective hose 202, the double-direction special-shaped pipe 211, and the double-drawing special-shaped pipe 213. The external impurities are intercepted by the intercepting net plate 228. The accumulated water will enter the inside of the intercepting fixed barrel 221 along the double-direction special-shaped pipe 211 and the double-drawing special-shaped pipe 213. At this time, the large-particle impurities will be restricted inside the intercepting fixed barrel 221 under the action of the concave limit, realizing the collection and interception of impurities, reducing the impact of impurity accumulation inside the pipeline on the normal operation of the pipeline, and finally pumping the accumulated water into the inside of the centralized fixed box 208, realizing the drainage treatment of the field, facilitating pressure-controlled drip irrigation, spraying, and pumping, enabling the plants to use this equipment for independent operation in different growth periods and growth environments, reducing the required equipment quantity, improving the automation degree of the equipment, and reducing the operation complexity;

[0078] The accumulated water is discharged into the inner side of the centralized fixing box 208 along the extraction fixing pipe 204. At this time, the accumulated water is discharged to the position of the filter screen plate 316 along the extraction fixing pipe 204. The two groups of filter screen plates 316 are used to filter and intercept the accumulated water to realize the recycling of the accumulated water. When the accumulated water accumulates to the highest position of the centralized fixing box 208, the slag discharge fixing pipe 317 is opened through the treatment valve 318, and the rainwater and the impurities on the filter screen plate 316 are discharged by the water flow, realizing self-cleaning of slag, ensuring the stability of the rainwater recycling and purification treatment. The impurities in the water fertilizer are intercepted by the intercepting sinking cylinder 312, and the water fertilizer in the mixing treatment box 301 is discharged into the inner side of the multi-ring blocking cylinder 313 through the liquid discharge fixing pipe 311. The water fertilizer is intercepted and limited by the multi-ring blocking cylinder 313 and finally enters the inner side of the discharge installation barrel 314, realizing the filtering treatment of the water fertilizer, reducing the entry of impurities into the pipeline to block the pipeline, and ensuring the stable operation. The rainwater in the centralized fixing box 208 is discharged into the inner side of the storage fixing box 205 through the reflux pump 307 and the reflux injection pipe 306, realizing the recycling of the rainwater. The two-way pump 209 and the treatment valve 318 cooperate with the extraction fixing pipe 204 and the bottom extraction pipe 309 to perform the water inlet and outlet operations, realizing the treatment in different environments.
