Its main function is to accurately apply irrigation water and fertilizer solution according to the characteristics of sandy soil and crop growth needs, so as to improve the utilization efficiency of water and nutrients, reduce waste and loss. The water and fertilizer control equipment for sandy soil is a device specially used in sandy soil environment, which can accurately control the supply of water and fertilizer. Its main function is to accurately apply irrigation water and fertilizer solution according to the characteristics of sandy soil and crop growth needs, so as to improve the utilization efficiency of water and nutrients, reduce waste and loss. Long-term use of water and fertilizer control equipment can improve the structure of sandy soil to a certain extent. Through reasonable irrigation and fertilization, the organic matter content in the soil can be increased and the formation of soil aggregates can be promoted.

[0003] When water and fertilizer are mixed in the water-fertilizer equipment, the water is forced into the connecting pipe by the pressure provided by the water pump or the natural water head to mix the water. However, since natural water often contains some impurities, it is necessary to filter the natural water through a filter plate when mixing the natural water and fertilizer. However, when the filtration is performed for a long time, the impurities in the natural water will clog the filter plate, thereby affecting the normal water inlet mixing work. Summary of the invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is: a water and fertilizer regulating device for sandy soil using a water and fertilizer retaining product according to the present invention comprises:

[0006] A filter component, which is used to filter the water flow entering the connecting pipe for water-fertilizer mixing, and the side of the filter component is fixedly connected to an end of the connecting pipe away from the discharge component;

[0007] The filter component comprises a filter housing, a side of the filter housing is fixedly connected to the connecting pipe, a filter screen plate is fixedly connected to the inner side of the filter housing, both sides of the filter screen plate are fixedly connected to telescopic rods, one end of the telescopic rod away from the filter screen plate is fixedly connected to a grid frame, a first spring is sleeved on the telescopic rod, one end of the first spring is fixedly connected to the filter screen plate, the other end of the first spring is fixedly connected to the grid frame, a side of the grid frame close to the filter screen plate is fixedly connected to an ejection mechanism, and the ejection mechanism is concentrically arranged with the mesh of the filter screen plate; when the water pump is connected to the filter housing through an external pipeline, By turning on the water pump, water flows through the filter housing to flow into the connecting pipe, so that the filter plate filters impurities in the water. When the water flows through the filter housing, the impact force of the water flow causes the grid frame to drive the ejection mechanism to move to the side away from the filter plate. At the same time, when the filter plate filters the water and the mesh holes in the filter plate are blocked, when the impact force of the water flowing through the filter plate is less than the tensile force of the first spring, the first spring drives the ejection mechanism to move toward the mesh holes of the filter plate through the grid frame, so that the ejection mechanism ejects the impurities blocked in the mesh holes of the filter plate.

[0008] Preferably, the ejection mechanism includes an ejection rod, the side of the ejection rod is evenly provided with notches, the inner side of the notch is slidably connected with a slider, the side of the slider is fixedly connected with a slide rod, the side of the slide rod is slidably connected to the inner side of the ejection rod, the end of the slide rod away from the slide rod is fixedly connected with an ejector pin, a second spring is sleeved on the slide rod, one end of the second spring is fixedly connected to the ejector pin, and the other end of the second spring is fixedly connected to the ejection rod; when the impact force of water flowing through the filter screen is less than the tensile force of the first spring, the first spring drives the ejection rod to move toward the mesh of the filter screen through the mesh frame , so that the ejector rod can eject the impurities blocked in the mesh of the filter plate through the ejector pin. At the same time, when the impurities blocked in the mesh of the filter plate are tightly stuck to the inner side of the mesh, the extrusion force between the ejector pin and the impurities is greater than the tensile force of the second spring. The ejector pin drives the slider to move in the notch through the slide bar, so as to perform extrusion buffering between the ejector pin and the impurities stuck in the mesh, thereby avoiding excessive extrusion force between the ejector pin and the impurities stuck in the inner side of the mesh, which will cause extrusion damage to the ejector pin, and also avoiding excessive extrusion friction between the impurities and the inner side of the mesh, which will cause the mesh diameter of the filter plate to become larger;

[0009] Preferably, the mixing component comprises a mixing shell, both sides of the top of the mixing shell are fixedly connected with discharge ports, the bottom of the mixing shell is fixedly connected with a bottom plate, both sides of the top of the bottom plate are provided with limit grooves, both sides of the bottom plate away from the mixing shell are fixedly connected with a one-way water outlet valve, the side of the bottom plate is slidably connected with a connecting shaft, and the top of the connecting shaft is fixedly connected with a connecting mechanism; before the water and fertilizer regulation work is carried out, a large amount of fertilizer liquid is added to the mixing shell through the discharge port, so that when the water flows into the connecting pipe through the filter component, the water flows through the filter component. The continuous impact drives the rotating blades to rotate inside the connecting pipe, so that the rotating blades and the connecting mechanism are squeezed, so that the fertilizer liquid in the mixing shell flows into the connecting pipe through the one-way water outlet valve. At the same time, the water flow continues to pass through the connecting pipe, driving the rotating blades to rotate in the connecting pipe. The rotating blades fully mix the fertilizer liquid and the water flow entering the connecting pipe. When the impact force of the water flow through the connecting pipe is greater, more fertilizer liquid flows out of the mixing shell, so that the fertilizer can be evenly mixed in the water flow passing through the connecting pipe.

[0010] Preferably, the connecting mechanism includes a connecting plate, the side surface of the connecting plate is fixedly connected to the top of the connecting shaft, both sides of the bottom of the connecting plate are fixedly connected to connecting blocks, the side surface of the connecting block is slidably connected to the inner side of the bottom plate, the middle part of the side surface of the connecting plate is fixedly connected to an extrusion rod, the side surface of the extrusion rod is slidably connected to the inner side of the bottom plate, the bottom of the extrusion rod is fixedly connected to the extrusion plate, a fourth spring is sleeved on the extrusion rod, the top of the fourth spring is fixedly connected to the connecting plate, the bottom of the fourth spring is fixedly connected to the top of the bottom plate, the side surface of the connecting plate is rotatably connected to the connecting plate, and the side of the connecting plate away from the connecting plate is rotatably connected to Contact assembly; when the water flow continues to pass through the connecting pipe, the water flow drives the rotating blade to rotate in the connecting pipe, and at the same time, the rotating blade continuously squeezes the extrusion plate when rotating, so that the extrusion plate is subjected to the extrusion force through the extrusion rod, driving the connecting plate to move upward in the inner cavity of the mixing shell, so that the connecting plate drives the connecting block to separate from the inner side of the bottom plate, so that the fertilizer liquid in the mixing shell flows into the connecting pipe through the one-way water outlet valve, and then the rotating blade drives the fertilizer liquid and the water flow to be fully mixed and stirred, and at the same time, when the connecting plate moves upward in the inner cavity of the mixing shell, the connecting plate drives the contact mechanism to slide in the limit groove through the connecting plate;

[0011] Preferably, the contact assembly includes a contact frame, the side surface of the contact frame is rotatably connected to an end of the connecting plate away from the connecting plate, the side surface of the contact frame is fixedly connected to a bent plate, the bottom of the bent plate is slidably connected to the inner side of the limiting groove through a limiting block, the side of the contact frame away from the bent plate is fixedly connected to a contact plate, and the side surface of the contact plate is evenly provided with clearance holes; when the connecting plate is driven to move upward in the inner cavity of the mixing shell by the extrusion plate and the extrusion rod, the connecting plate pulls the contact frame to move through the connecting plate, so that the bent plate slides in the limiting groove through the limiting block, so that when the connecting plate moves upward in the mixing shell, the contact frame drives the bent plate and the contact plate to push the fertilizer liquid gathered around the bottom plate to the middle of the bottom plate, Therefore, the fertilizer liquid around the bottom plate can be gathered to the middle of the bottom plate, and the material can be discharged through the one-way water outlet valve, so as to avoid that when the fertilizer liquid in the inner cavity of the mixing shell is not much, it is difficult to flow out the small amount of fertilizer liquid stored in the inner cavity of the mixing shell. At the same time, the contact plate is evenly provided with clearance holes, so that when the contact frame and the connecting plate are reset by the reset pull of the fourth spring, the connecting plate can drive the contact frame to move to the two sides of the bottom plate through the connecting plate, so as to avoid the fertilizer liquid gathered on both sides of the contact plate and the bottom plate from being squeezed, causing the contact frame to be squeezed and slipped, and then causing the connecting plate to drive the connecting block to separate from the inner side of the bottom plate, causing the one-way water outlet valve to drip, thereby interfering with the mixing work;

[0012] Preferably, the discharging component comprises a discharging shell, the side surface of the discharging shell is fixedly connected to an end of the connecting pipe away from the filtering shell, the inner side of the discharging shell is fixedly connected to a fixing frame, the side surface of the fixing frame is fixedly connected to a guide rod, the other end of the guide rod is fixedly connected to the inner side of the discharging shell, the side of the discharging shell away from the fixing frame is fixedly connected to the discharging pipe, the fixing frame is fixedly connected to a third spring, and the end of the third spring away from the fixing frame is fixedly connected to a scraper mechanism; when the water flow continues to pass through the connecting pipe, the rotating blade is driven to fully mix the water flow and fertilizer liquid in the connecting pipe, and the mixed fertilizer solution flows through the discharging shell, flows out from the discharging pipe, and is connected to the discharging pipe through an external irrigation water pipe, so as to irrigate the sandy soil, and at the same time, the impact force when the mixed fertilizer solution passes through the discharging shell causes the scraper mechanism to pull the third spring to slide on the guide rod, so that the scraper mechanism contacts and cleans the inner side of the discharging shell;

[0013] The scraper mechanism includes a connecting frame, a through hole is provided on the side of the connecting frame, the inner side of the through hole is slidably connected to the side of the guide rod, and scrapers are fixedly connected to both sides of the connecting frame, the side of the scraper away from the connecting frame is in contact with the inner wall of the discharge shell, and the side of the connecting frame is fixedly connected to the end of the third spring away from the fixed frame; the impact force when the mixed fertilizer solution passes through the discharge shell causes the connecting frame to move on the guide rod through the through hole, so that the connecting frame drives the scraper to clean and scratch the inner wall of the discharge shell, thereby preventing the fertilizer solution from passing through for a long time, and part of the fertilizer solution fails to completely merge with the water flow, so that it will accumulate on the inner side of the discharge shell, causing corrosion to the inner wall of the discharge shell.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention provides a filter component. When the water pump is connected to the filter housing through an external pipe, the water pump is turned on to allow water to flow through the filter housing into the connecting pipe, so that the filter plate filters impurities in the water. When the water flows through the filter housing, the impact force of the water flow causes the grid to drive the ejection mechanism to move to a side away from the filter plate. At the same time, when the filter plate filters the water and the mesh holes in the filter plate are blocked, when the impact force of water flowing through the filter plate is less than the tensile force of the first spring, the first spring drives the ejection mechanism to move toward the mesh holes of the filter plate through the grid, so that the ejection mechanism ejects the impurities blocked in the mesh holes of the filter plate.

[0016] 2. The present invention provides an ejection mechanism. When the impact force of water flowing through the filter screen is less than the tensile force of the first spring, the first spring drives the ejection rod to move toward the mesh holes of the filter screen through the grid frame, so that the ejection rod ejects the impurities blocked in the mesh holes of the filter screen through the ejector pin. At the same time, when the impurities blocked in the mesh holes of the filter screen are tightly stuck to the inner side of the mesh holes, the extrusion force between the ejector pin and the impurities is greater than the tensile force of the second spring, the ejector pin drives the slider to move in the notch through the slide rod, so as to perform extrusion and buffering between the ejector pin and the impurities stuck in the mesh holes, thereby avoiding excessive extrusion force between the ejector pin and the impurities stuck in the inner side of the mesh holes, which would cause extrusion damage to the ejector pin, and also avoiding excessive extrusion friction between the impurities and the inner side of the mesh holes, which would cause the mesh hole diameter of the filter screen to become larger.

[0017] 3. The present invention provides a water outlet component. When the water flows continuously through the connecting pipe, the rotating blades are driven to fully mix the water flow and the fertilizer liquid in the connecting pipe. The mixed fertilizer solution flows through the discharge shell and flows out from the discharge pipe. The discharge pipe is connected to the discharge pipe through an external irrigation water pipe, so as to irrigate sandy soil. At the same time, the impact force of the mixed fertilizer solution when passing through the discharge shell causes the scraper mechanism to pull the third spring to slide on the guide rod, so that the scraper mechanism contacts and cleans the inner side of the discharge shell.

[0018] 4. The present invention provides a mixing component. Before water and fertilizer regulation, a large amount of fertilizer liquid is added to the mixing shell through the discharge port. When the water flows into the connecting pipe through the filter component, the continuous impact of the water flow drives the rotating blades to rotate inside the connecting pipe, so that the rotating blades and the connecting mechanism are squeezed, so that the fertilizer liquid in the mixing shell flows into the connecting pipe through the one-way water outlet valve. At the same time, the water flows continuously through the connecting pipe, driving the rotating blades to rotate in the connecting pipe. The rotating blades fully mix the fertilizer liquid and water flowing into the connecting pipe. When the impact force of the water flowing through the connecting pipe is greater, more fertilizer liquid flows out of the mixing shell, so that the fertilizer can be evenly mixed in the water flowing through the connecting pipe.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0031] Example 1, using Figure 1-Figure 5 A water and fertilizer control device for sandy soil using a water and fertilizer retention product according to one embodiment of the present invention is described as follows;

[0032] like Figure 1-Figure 5 The present invention shows a water and fertilizer control device for sandy soil using a water and fertilizer retention product, comprising:

[0033] A connecting pipe 1, a support frame 2 is fixedly connected to the side of the connecting pipe 1, a mixing component 4 is fixedly connected to the side of the connecting pipe 1 away from the support frame 2, a discharging component 5 is fixedly connected to one end of the connecting pipe 1, and brackets 7 are fixedly connected to both sides of the inner cavity of the connecting pipe 1, and rotating blades 6 are rotatably connected to the side of the bracket 7;

[0034] A filter component 3, which is used to filter the water flow entering the connecting pipe 1 for water-fertilizer mixing, and a side surface of the filter component 3 is fixedly connected to an end of the connecting pipe 1 away from the discharge component 5;

[0035] The filter component 3 includes a filter housing 31, the side of the filter housing 31 is fixedly connected to the connecting pipe 1, the inner side of the filter housing 31 is fixedly connected to a filter plate 32, both sides of the filter plate 32 are fixedly connected to telescopic rods 33, one end of the telescopic rod 33 away from the filter plate 32 is fixedly connected to a grid frame 34, a first spring 36 is sleeved on the telescopic rod 33, one end of the first spring 36 is fixedly connected to the filter plate 32, the other end of the first spring 36 is fixedly connected to the grid frame 34, and a side of the grid frame 34 close to the filter plate 32 is fixedly connected to an ejection mechanism 37, and the ejection mechanism 37 is concentrically arranged with the mesh of the filter plate 32; when the water pump is connected to the filter housing 31 through an external pipeline, by opening The water pump allows the water to flow through the filter housing 31 into the connecting pipe 1, so that the filter plate 32 filters the impurities in the water. When the water flows through the filter housing 31, the impact force of the water flow causes the rack 34 to drive the ejection mechanism 37 to move to the side away from the filter plate 32. At the same time, when the filter plate 32 filters the water, when the mesh holes in the filter plate 32 are blocked, when the impact force of the water flowing through the filter plate 32 is less than the tensile force of the first spring 36, the first spring 36 drives the ejection mechanism 37 to move to the mesh holes of the filter plate 32 through the rack 34, so that the ejection mechanism 37 ejects the impurities blocked in the mesh holes of the filter plate 32.

[0036] The ejection mechanism 37 includes an ejection rod 371, and slots 372 are evenly provided on the side of the ejection rod 371. A slider 373 is slidably connected to the inner side of the slot 372. A slide bar 374 is fixedly connected to the side of the slide bar 373. The side of the slide bar 374 is slidably connected to the inner side of the ejection rod 371. An ejector pin 375 is fixedly connected to one end of the slide bar 374 away from the slide bar 373.

One end of the second spring 376 is fixedly connected to the ejector pin 375, and the other end of the second spring 376 is fixedly connected to the ejection rod 371. When the impact force of water flowing through the filter screen plate 32 is less than the tensile force of the first spring 36, the first spring 36 drives the ejection rod 371 to the mesh of the filter screen plate 32 through the mesh frame 34. The ejector rod 371 is moved so that the impurities blocked in the mesh of the filter plate 32 are ejected through the ejector pin 375. At the same time, when the impurities blocked in the mesh of the filter plate 32 are tightly stuck to the inner side of the mesh, the extrusion force between the ejector pin 375 and the impurities is greater than the tensile force of the second spring 376. The ejector pin 375 drives the slider 373 to move in the notch 372 through the slide bar 374, so that the ejector pin 375 and the impurities stuck in the mesh are squeezed and buffered, thereby avoiding excessive extrusion force between the ejector pin 375 and the impurities stuck in the mesh, which would cause extrusion damage to the ejector pin 375, and also avoiding excessive extrusion friction between the impurities and the inner side of the mesh, which would cause the mesh aperture of the filter plate 32 to become larger.

The external irrigation water pipe is connected to the discharge pipe 52, so as to irrigate the sandy soil. At the same time, the impact force of the mixed fertilizer solution passing through the discharge housing 51 causes the scraper mechanism 56 to pull the third spring 55 to slide on the guide rod 54, so that the scraper mechanism 56 contacts and cleans the inner side of the discharge housing 51.

[0045] The scraper mechanism 56 includes a connecting frame 561, a through hole 562 is provided on the side of the connecting frame 561, the inner side of the through hole 562 is slidably connected to the side of the guide rod 54, and scrapers 563 are fixedly connected to both sides of the connecting frame 561. The side of the scraper 563 away from the connecting frame 561 contacts the inner wall of the discharge housing 51, and the side of the connecting frame 561 is fixedly connected to the end of the third spring 55 away from the fixed frame 53; the impact force when the mixed fertilizer solution passes through the discharge housing 51 causes the connecting frame 561 to move on the guide rod 54 through the through hole 562, so that the connecting frame 561 drives the scraper 563 to clean and scratch the inner wall of the discharge housing 51, thereby preventing the fertilizer solution from passing for a long time, and part of the fertilizer solution fails to completely merge with the water flow, so that it will accumulate on the inner side of the discharge housing 51, causing corrosion to the inner wall of the discharge housing 51;

[0046] The specific workflow is as follows:

[0047] First, in the water and fertilizer control equipment for retaining water and fertilizer in sandy soil, the mixing component can ensure that fertilizer and water are evenly mixed. In sandy soil, uneven water and fertilizer distribution may lead to excessive or low local nutrient concentrations. The evenly mixed water and fertilizer can be more evenly distributed to the soil during irrigation to avoid "root burn" of plants due to excessive local nutrient concentrations, or poor growth due to insufficient local nutrients. The fertilizer storage device is used to store various fertilizers, such as compound fertilizers, organic fertilizers, etc. During the mixing process, the fertilization component needs to transport the fertilizer to the mixing component in a certain proportion. The beam transport speed must match the output speed of the mixing component. The mixing component is connected to the control system through a signal line or a wireless communication module. The mixing component receives the control instructions issued by the control system so that the control system can coordinate and manage the whole.

[0048] Based on soil nutrient monitoring data and crop fertilization models, the amount, time and type of fertilizers can be precisely controlled, and the irrigation system and fertilization device can be organically combined to achieve integrated water and fertilizer management. Irrigation and fertilization can be carried out simultaneously through the same set of pipe systems, so that fertilizers can quickly penetrate into the roots of crops along with water, thereby improving fertilizer utilization and reducing nutrient loss. With the help of Internet of Things technology and mobile Internet, users can remotely monitor the operating status of water and fertilizer control equipment, soil and crop information, etc. through mobile phone APP or computer terminals, and can adjust parameters and issue control instructions anytime and anywhere, thereby improving management efficiency and flexibility.

[0049] During operation, water is passed through the filter component 3 through the pressure provided by the water pump or the natural water head, and then enters the connecting pipe 1 after being filtered. The impact force of the water flow entering the connecting pipe 1 causes the rotating blade 6 to rotate in the inner cavity of the connecting pipe 1, so that the mixing component 4 can evenly feed the material according to the size of the water flow, and then connect with the discharge component 5 through the external irrigation water pipe. The dripper on the irrigation water pipe slowly drips into the soil in a drip manner, and the fertilizer solution enters the drip irrigation together with the irrigation water pipe, so as to realize the precise water and fertilizer supply. For fertilizer, sandy soil has a high demand for fertilizer. The adsorption capacity of fertilizer is weak, and fertilizer is easily leached with water. Therefore, on the one hand, fertilizer preservation products such as coated controlled-release fertilizers should be used to gradually release fertilizer nutrients according to the plant growth stage and environmental conditions (such as temperature and humidity). On the other hand, the mixing component 4 is combined with an external irrigation system to dissolve the fertilizer and inject it into the irrigation water to achieve synchronous supply of water and fertilizer, accurately control the amount of fertilizer and fertilization time, so that the fertilizer can maintain a suitable concentration around the plant root system for plant absorption, while reducing fertilizer leaching losses, and formulating a fertilization plan according to the nutrient requirements of crops at different growth stages;

[0050] When the water pump is connected to the filter housing 31 through the external pipe, the water pump is turned on so that the water flows through the filter housing 31 to flow into the connecting pipe 1, so that the filter plate 32 filters the impurities in the water. When the water flows through the filter housing 31, the impact force of the water flow causes the rack 34 to drive the ejection mechanism 37 to move to the side away from the filter plate 32. At the same time, when the filter plate 32 filters the water, when the mesh holes in the filter plate 32 are blocked, when the impact force of the water flowing through the filter plate 32 is less than the tensile force of the first spring 36, the first spring 36 drives the ejection mechanism 37 to move to the mesh holes of the filter plate 32 through the rack 34, so that the ejection mechanism 37 ejects the impurities blocked in the mesh holes of the filter plate 32.

[0051] When the impact force of water flowing through the filter screen 32 is less than the tensile force of the first spring 36, the first spring 36 drives the ejection rod 371 to move toward the mesh of the filter screen 32 through the mesh frame 34, so that the ejection rod 371 ejects the impurities blocked in the mesh of the filter screen 32 through the ejector pin 375. At the same time, when the impurities blocked in the mesh of the filter screen 32 are tightly stuck to the inner side of the mesh, the extrusion force between the ejector pin 375 and the impurities is greater than the tensile force of the second spring 376, the ejector pin 375 drives the slider 373 to move in the notch 372 through the slide rod 374, so as to perform extrusion buffering between the ejector pin 375 and the impurities stuck in the mesh, thereby avoiding excessive extrusion force between the ejector pin 375 and the impurities stuck in the inner side of the mesh, which would cause extrusion damage to the ejector pin 375, and also avoiding excessive extrusion friction between the impurities and the inner side of the mesh, which would cause the mesh aperture of the filter screen 32 to become larger.

[0052] Before water and fertilizer regulation, a large amount of fertilizer liquid is added to the mixing housing 41 through the discharge port 42, so that when the water flows through the filter component 3 and enters the connecting pipe 1, the continuous impact of the water flow drives the rotating blades 6 to rotate inside the connecting pipe 1, so that the rotating blades 6 and the connecting mechanism 47 are squeezed, so that the fertilizer liquid in the mixing housing 41 flows into the connecting pipe 1 through the one-way water outlet valve 46. At the same time, the water flows continuously through the connecting pipe 1, driving the rotating blades 6 to rotate in the connecting pipe 1. The rotating blades 6 fully mix the fertilizer liquid and the water flow entering the connecting pipe 1. When the impact force of the water flow through the connecting pipe 1 is greater, more fertilizer liquid flows out of the mixing housing 41, so that the fertilizer can be evenly mixed in the water flow passing through the connecting pipe 1.

[0053] When the water flow continues to pass through the connecting pipe 1, the rotating blade 6 is driven by the water flow to rotate in the connecting pipe 1. At the same time, the rotating blade 6 continuously squeezes the squeezing plate 474 when it rotates, so that the squeezing plate 474 is subjected to the squeezing force through the squeezing rod 473, driving the connecting plate 471 to move upward in the inner cavity of the mixing shell 41, so that the connecting plate 471 drives the connecting block 472 to separate from the inner side of the bottom plate 43, so that the fertilizer liquid in the mixing shell 41 flows into the connecting pipe 1 through the one-way water outlet valve 46, and then the rotating blade 6 drives the fertilizer liquid and the water flow to be fully mixed and stirred. At the same time, when the connecting plate 471 moves upward in the inner cavity of the mixing shell 41, the connecting plate 471 drives the contact mechanism to slide in the limiting groove 44 through the connecting plate 476;

[0054] When the connecting plate 471 is driven by the squeezing plate 474 and the squeezing rod 473 to move upward in the inner cavity of the mixing shell 41, the connecting plate 471 pulls the contact frame 4771 to move through the connecting plate 476, so that the bent plate 4772 slides in the limiting groove 44 through the limiting block, so that when the connecting plate 471 moves upward in the mixing shell 41, the contact frame 4771 drives the bent plate 4772 and the contact plate 4773 to push the fertilizer liquid gathered around the bottom plate 43 to the middle part of the bottom plate 43, so that the fertilizer liquid around the bottom plate 43 can be gathered to the middle part of the bottom plate 43, and the discharge work is performed through the one-way water outlet valve 46, so as to avoid the fertilizer liquid in the inner cavity of the mixing shell 41 from being stored. When there is too much fertilizer, it is difficult to let out the small amount of fertilizer liquid stored in the inner cavity of the mixing shell 41. At the same time, the contact plate 4773 is evenly provided with the clearance holes 4774, so that when the contact frame 4771 and the connecting plate 471 are reset by the reset pull of the fourth spring 475, the connecting plate 471 can drive the contact frame 4771 to move to the two sides of the bottom plate 43 through the connecting plate 476, so as to avoid the fertilizer liquid gathered on both sides of the contact plate 4773 and the bottom plate 43 from being squeezed, causing the contact frame 4771 to be squeezed and slipped, and then causing the connecting plate 471 to drive the connecting block 472 to separate from the inner side of the bottom plate 43, causing the one-way water outlet valve 46 to drip, thereby interfering with the mixing work;

[0055] When the water flow continues to pass through the connecting pipe 1, the rotating blades 6 are driven to fully mix the water flow and the fertilizer solution in the connecting pipe 1. The mixed fertilizer solution flows through the discharge housing 51 and flows out from the discharge pipe 52. The external irrigation water pipe is connected to the discharge pipe 52, so as to irrigate the sandy soil. At the same time, the impact force of the mixed fertilizer solution passing through the discharge housing 51 causes the scraper mechanism 56 to pull the third spring 55 to slide on the guide rod 54, so that the scraper mechanism 56 contacts and cleans the inner side of the discharge housing 51.

[0056] The impact force of the mixed fertilizer solution when passing through the discharge shell 51 causes the connecting frame 561 to move on the guide rod 54 through the through hole 562, so that the connecting frame 561 drives the scraper 563 to clean and scratch the inner wall of the discharge shell 51, thereby preventing the fertilizer solution from passing for a long time and part of the fertilizer solution from failing to completely merge with the water flow, thereby accumulating on the inner side of the discharge shell 51 and causing corrosion to the inner wall of the discharge shell 51.
