Description

Technical Field

[0001] The invention belongs to the technical field of water and fertilizer machines, and in particular relates to an integrated irrigation and fertilization machine for gardening and a method for irrigation and fertilization. Background Art

[0002] As an outstanding product of modern agricultural technology, the integrated fertilization and irrigation machine integrates the dual functions of irrigation and fertilization. The integrated fertilization and irrigation machine is usually composed of a cloud platform, a data acquisition terminal, a fertilizer machine, a filtration system, a valve controller, a solenoid valve, and field pipelines. It can monitor the moisture and nutrient status of the soil in real time, and at the same time, combined with the fertilizer requirements of the crop types, according to the irrigation and fertilization schemes pre-set by the user, intelligently adjust the irrigation amount, fertilizer absorption, fertilizer concentration, pH and other key parameters, so that the integrated fertilization and irrigation machine can achieve accurate, timed, and quantitative control of the irrigation and fertilization process, greatly improve the efficiency of water and fertilizer use, and achieve the goal of saving water and fertilizer. At the same time, it helps to improve the soil environment and improve the overall quality of crops. In addition, the integrated fertilization and irrigation machine is widely used in various planting scenarios such as fields, greenhouses and gardens, and has multiple advantages such as saving labor, fertilizer, water, environmental protection and soil protection.

[0003] Based on the above, although the integrated fertilization and irrigation machine has become an indispensable tool in modern agriculture with its high efficiency and intelligence, there are still other problems that need to be solved. For example, the integrated fertilization and irrigation machine may not be able to effectively remove impurities in the water source when pumping water, such as suspended particles, organic matter and microorganisms. Due to insufficient filtration accuracy, impurities in the water cannot be completely removed, which may have a negative impact on the irrigation water quality, and thus fail to meet high standards of irrigation quality requirements, reducing the expected effect of irrigation and fertilization.

[0011] In a preferred embodiment, a water stop plate is provided at the position where the primary filter pipe is connected to the lower tube. The water stop plate is located below the lower tube and extends along the inclination direction of the lower tube. A vertical water cut-off plate is provided at the top of the water stop plate corresponding to the lower tube. The water cut-off plate is adapted to be inserted into the lower tube.

[0012] In a preferred embodiment, an upper water outlet is provided on the circumferential side of the primary filter pipe at a position corresponding to the secondary filter detour pipe, and a lower water outlet is also provided on the primary filter pipe below the upper water outlet.

This process mainly intercepts some long, light-weight debris such as waterweed and withered grass. The water body enters the secondary filtration bypass pipe by inertia or overflows from the lower water inlet into the main channel. Finally, the water flow that has been filtered twice in the secondary filtration bypass pipe finally converges into the main channel and flows to the tertiary filtration pipeline.

[0025] In the present invention, when the water flows into the interior of the secondary filtering detour, it will first enter the annular filter screen, which can intercept sand, gravel, stone particles or other solid impurities in the water body, and can effectively capture those fine particles and impurities that cannot be intercepted by the primary filtration. Such a secondary filtering mechanism ensures that the water quality reaches a high degree of cleanliness before mixing fertilizer, avoiding the burden of blocking the dropper. The combination of the secondary filtering detour and the annular filter screen not only improves the filtration quality, but also ensures the smoothness of the water flow and reduces the resistance of the water flow. In addition, the inclination and bending design of the secondary filtering detour enables the water flow to generate a certain centrifugal force when passing through, which helps to throw impurities such as sand, gravel and stone particles to the pipe wall, further improving the filtration effect.

[0026] In the present invention, although the water that overflows directly from the lower water outlet into the main channel bypasses the fine filtration of the secondary filter detour, all the water that passes through the secondary filter detour or directly comes from the lower water outlet, after converging into the main channel, will flow to the tertiary filter pipe for final fine processing, ensuring that the water quality output by the irrigation and fertilization integrated machine meets the requirements of landscaping, and the water filtration interlayer helps to adsorb suspended matter floating in the water, such as small particle impurities and some soluble organic matter, to further improve the clarity of the water quality. The synergistic effect of the primary filter pipe, the secondary filter detour and the tertiary filter pipe not only enhances the filtering effect, but also ensures that the water flow is unobstructed, avoids the occurrence of blockage, and greatly improves the purity of the water quality.

The water source flows out from the water outlet after multi-stage filtration through the multi-stage filter assembly 1. The multi-stage filter assembly 1 is connected to the fertilizer barrel 3 through the connecting pipe 2. The water source enters the interior of the fertilizer barrel 3 after multi-stage filtration. One port of the industrial water pump 4 is connected to the fertilizer barrel 3, and the other port is installed with a ball valve 5 through a straight pipe. The ball valve 5 is connected to the ball valve 5. Drip irrigation system, when the industrial water pump 4 is in operation, the water and fertilizer in the fertilizer barrel 3 are pumped out, the ball valve is opened, and the landscaping is drip-irrigated through the drip irrigation system, wherein the drip irrigation system includes a water supply and distribution network, a dripper or a drip irrigation belt, etc., and the water and fertilizer are slowly delivered to the roots of crops in a drip manner through tiny pores. The drip irrigation system is composed of the current prior art and will not be described in detail here. The fertilizer suction pipe 6 is provided with at least two routes, one end of the fertilizer suction pipe 6 is connected to the fertilizer barrel 3, and the other end is connected to the water fertilizer barrel. The fertilizer suction pipe 6 is used to pump the fertilizer liquid in the water fertilizer barrel into the interior of the fertilizer barrel 3; the fertilizer liquid in the fertilizer barrel 3 is mixed with clean water after proportioning, and then the fertilizer liquid in the fertilizer barrel 3 is pumped out through the industrial water pump 4, and the control end 7 is arranged on one side of the fertilizer barrel 3.

[0047] Among them, the amount of fertilizer entering the fertilizer suction pipe 6, the water intake of the multi-stage filter assembly 1, and the water discharge time of the industrial water pump 4 are controlled. It is worth mentioning that the control terminal 7 is programmed by a program to control each component. In this application, the control terminal 7 still has control authority over unmentioned components, and the above-mentioned components and control steps are given priority.

[0048] Please refer again Figure 3-4The multi-stage filtering assembly 1 includes a primary filtering pipe 102, the primary filtering pipe 102 is provided with a main channel 109 extending vertically downward, and also includes a secondary filtering bypass pipe 103, the secondary filtering bypass pipe 103 is divided into an upper pipe 1031 and a lower pipe 1032 which are opposite to each other, the upper pipe 1031 and the lower pipe 1032 are both threadedly connected to the peripheral side of the primary filtering pipe 102, and the upper pipe 1031 and the lower pipe 1032 have a spacing for water flow to pass through, and are communicated with the primary filtering pipe 102, wherein, during installation, the lower pipe 1032 and the upper pipe 1031 are firstly sleeved on the outside of the primary filtering pipe 102 in sequence and threadedly connected thereto, so that the lower pipe 1 032 is smoothly connected with the upper and lower threads of the upper tube 1031, and the table protrudes outward at the position where the primary filter pipe 102 and the lower tube 1032 are threadedly connected, so that the lower thread diameter of the primary filter pipe 102 is larger than the upper thread diameter, so that the upper tube 1031 and the lower tube 1032 can be smoothly threadedly sleeved on the primary filter pipe 102, and also includes a tertiary filter pipe 113, the tertiary filter pipe 113 is arranged below the primary filter pipe 102 and is fixed to the connecting pipe 2. The water source passes through the primary filter pipe 102, the secondary filter detour pipe 103, and the tertiary filter pipe 113 for step-by-step filtration and finally flows into the interior of the tertiary filter pipe 113.

[0049] Please refer again Figure 4-5 The bottom port position of the first-level filter pipe 102 extends outward to form a boss 1021, and a groove 1022 is provided on the top of the boss 1021. The upper tube 1031 is adapted to the boss 1021 and is provided with a notch 1033. A sealing strip 1034 is installed in the notch 1033. The sealing strip 1034 is provided with a protruding strip 1035 on the side facing the groove 1022. The sealing strip 1034 and the strip 1035 cooperate to seal and stop water.

[0050] Based on the above, the lower tube 1032 is connected to the upper tube 1031 by double threads, and water-stopping components are provided at the connection joints. The groove 1022 is used to accommodate the pressure strip 1035 of the sealing strip 1034 to ensure that the sealing strip 1034 can fit tightly. The pressure strip 1035 cooperates with the groove 1022 to form a sealed and water-stopping structure, and the upper tube 1031 is tightly connected to the primary filter pipe 102 by mechanical compression or bolt fixing, so as to achieve a sealed and water-stopping effect.

[0051] Please refer again Figure 6-7 A water stop plate 8 is provided at the position where the primary filter pipe 102 is connected to the lower tube 1032. The water stop plate 8 is located below the lower tube 1032 and extends along the inclined direction of the lower tube 1032. A vertical water cut-off plate 9 is provided at the top of the water stop plate 8 corresponding to the lower tube 1032. The water cut-off plate 9 is adapted to be inserted into the lower tube 1032.

[0052] Specifically, the water stop plate 8 extends obliquely and is fixed to the detour channel 107, and the water cut-off plate 9 is adapted to be inserted into the lower tube 1032, which further achieves a water stop effect and avoids leakage due to excessive water pressure.

[0053] More specifically, through the coordinated design of the sealing strip 1034, the pressure strip 1035, the water stop plate 8 and the water cut-off plate 9, the connection between the primary filter pipe 102 and the upper tube 1031 and the lower tube 1032 achieves an efficient closed water-stopping effect. This design structure can effectively prevent water leakage.

[0054] Please refer again Figure 7-8 An upper water inlet 104 is provided on the circumferential side of the primary filter pipe 102 at a position corresponding to the secondary filter detour pipe 103, and a lower water inlet 105 is provided on the primary filter pipe 102 below the upper water inlet 104. A fixing plate 110 is provided at a physical position between the upper water inlet 104 and the lower water inlet 105. The middle portion of the fixing plate 110 is concave, and a spring 111 is fixed at the concave position. A valve plate 112 is fixed to the top of the spring 111, and the valve plate 112 moves up and down in the primary filter pipe 102.

[0055] Under normal circumstances, the valve plate 112 is supported by the spring 111 and is pressed against the neck of the primary filter pipe 102. The interior of the primary filter pipe 102 is in a temporarily closed state. When water flows impact the valve plate 112, the valve plate 112 is compressed by the spring 111 and contracts. The upper water port 104 and the lower water port 105 are opened, and the water flows through the upper water port 104 into the interior of the secondary filter detour 103.

[0056] Based on the above structure, when the water flow hits the valve plate 112 and enters the upper water outlet 104, it is primary filtration. This process mainly intercepts some long, light debris such as aquatic plants and dead grass. The water body enters the secondary filter detour 103 by inertia or overflows from the lower water outlet 105 into the main channel 109. Finally, the water flow that has passed the secondary filtration in the secondary filter detour 103 eventually converges into the main channel 109 and flows to the tertiary filtration pipe 113.

[0057] Please refer again Figure 7-8 The secondary filter bypass pipe 103 tilts outward and then bends toward the primary filter pipe 102, and is connected with the primary filter pipe 102 to form a detour channel 107. An annular filter screen 106 is arranged at the bending portion 108 in the secondary filter bypass pipe 103, and the annular filter screen 106 is used to filter sand and gravel.

[0058] Specifically, when water flows into the secondary filter detour 103, it will first enter the annular filter 106. The annular filter 103 can intercept sand, gravel, stones or other solid impurities in the water body, and can effectively capture those fine particles and impurities that cannot be intercepted by the primary filtration. Such a secondary filtration mechanism ensures that the water quality reaches a higher level of cleanliness before mixing with fertilizer, avoiding blocking burden on the dropper. The combination of the secondary filter detour 103 and the annular filter 106 not only improves the filtration quality, but also ensures the smoothness of the water flow and reduces the resistance of the water flow. In addition, the inclined and bent design of the secondary filter detour 103 enables the water flow to generate a certain centrifugal force when passing through, which helps to throw impurities such as sand, gravel and stones to the pipe wall, further improving the filtration effect.

[0059] Please refer again Fig. 9 A protruding ring platform 119 is provided at a position inside the bending portion 108 and connected to the annular filter screen 106 for supporting the annular filter screen 106 .

[0060] Please refer again Fig.10 A fixing ring 114 is installed in the third-stage filtering pipe 113, an inner filter screen 115 is installed at the bottom of the fixing ring 114, an outer filter screen 116 is installed at the bottom of the fixing ring 114 and outside the inner filter screen 115, and a water filtering interlayer 117 is provided between the inner filter screen 115 and the outer filter screen 116.

[0061] Specifically, although the water that overflows directly from the lower water outlet 105 into the main channel 109 bypasses the fine filtration of the secondary filter detour 103, all the water that passes through the secondary filter detour 103 or directly comes from the lower water outlet 105, after converging into the main channel 109, will flow to the tertiary filter pipe 113 for final fine processing, ensuring that the water quality output by the irrigation and fertilization machine meets the requirements of landscaping, and the water filtration interlayer 117 helps to adsorb suspended matter floating in the water, such as small particle impurities and some soluble organic matter, to further improve the clarity of the water quality. The synergistic effect of the primary filter pipe 102, the secondary filter detour 103 and the tertiary filter pipe 113 not only enhances the filtration effect, but also ensures unimpeded water flow, avoids the occurrence of blockage, and greatly improves the purity of the water quality.

[0062] Please refer again Fig.10 A water permeable hole 118 is provided at the bottom of the inner filter screen 115, and the bottom of the outer filter screen 116 is closed.

[0063] More specifically, the closed design of the bottom of the outer filter 116 ensures that during the final filtration process, if there are solid particles in the water, they will settle at the bottom of the outer filter 116, and the water will pass through the water filter interlayer 117 to reach the fertilizer barrel 3, further ensuring the degree of impurity removal of the water flow and avoiding clogging of the dripper at the later stage. Based on the above structure, the multi-stage filtration system can effectively remove various pollutants in the water, including organic matter, inorganic matter, particles dispersed in the water, etc., thereby improving the safety and purity of the water quality.

[0064] Based on the above structure, the present application also provides an irrigation and fertilization method, which is described in detail in the following steps:

[0065] Step 1: Check the equipment: make sure that all components are connected properly, and check whether the drip irrigation system is intact, without blockage or leakage. Based on the inspection results, prepare the fertilizer solution and enter the fertilization parameters;

[0066] Specifically, the control terminal 7 inputs the fertilization parameters, including the amount of fertilizer, the time of fertilization, the concentration of fertilizer solution, etc., and the fertilizer is added to the water-fertilizer bucket to ensure that the fertilizer is evenly dissolved. The amount of fertilizer, the time of fertilization, and other parameters are determined according to the needs of the crops.

[0067] Step 2: The control terminal 7 sends a remote command to the water pump to pump the fertilizer liquid in the water fertilizer barrel into the fertilizer mixing barrel 3 through the fertilizer suction pipe 6;

[0068] Step 3: Introduce the water source into the multi-stage filtering assembly 1, perform multi-stage filtering, and then drain it into the fertilizer tank 3;

[0069] Multi-stage filtration process:

[0070] Primary filtration: Water enters the primary filtration pipe 102, the valve plate 112 is opened by the impact of the water flow, and the water flows into the secondary filtration bypass pipe 103 through the upper water inlet 104, or directly into the main channel 109 through the lower water inlet 105. The primary filtration mainly intercepts long debris such as waterweed and dead grass;

[0071] Secondary filtration: Water flows into the secondary filtration bypass pipe 103 and filters solid impurities such as sand and stone particles through the annular filter screen 106. The tilting and bending design of the secondary filtration bypass pipe 103 generates centrifugal force to further improve the filtration effect;

[0072] Three-stage filtration: The water flows into the three-stage filtration pipe 113, and is finally finely filtered through the inner filter 115 and the outer filter 116. The water filter interlayer 117 absorbs suspended matter to ensure the purity of water quality;

[0073] Step 4: The control terminal 7 automatically adjusts the mixing ratio of the fertilizer liquid and the clean water according to the input fertilization parameters, then opens the ball valve 5, and draws the fertilizer liquid to the drip irrigation system through the industrial water pump 4. The fertilizer liquid is transported to the dripper or drip irrigation belt through the water distribution network, and is slowly transported to the roots of the crops in a drip manner;

[0074] Step 5: The control terminal 7 monitors the fertilizer and water flow in the pipeline in real time through the sensor, and automatically stops fertilizing when the set fertilizer amount is reached.

[0075] The working principle of the present invention is as follows: water from a water pump is pumped into a multi-stage filter assembly 1 for multi-stage filtration. The synergistic effect of the primary filter pipe 102, the secondary filter pipe 103 and the tertiary filter pipe 113 in the multi-stage filter assembly 1 not only enhances the filtration effect, but also ensures that the water flows smoothly and avoids the occurrence of blockage, thereby greatly improving the purity of the water quality. At the same time, the three-way fertilizer suction pipe 6 on the fertilizer distribution barrel 3 inputs water and fertilizer into the fertilizer distribution barrel 3 in proportion, and after mixing with the clean water flowing in from the connecting pipe 2, flows into the drip irrigation system from the water outlet of the ball valve 5 to act on the roots of the crops.

[0076] In order to improve the quality of irrigation water and ensure the working effect of the fertigation machine, this application improves the fertigation machine to improve its filtering accuracy. Specifically, a multi-stage filtering device can be added at the water inlet of the fertigation machine. Each stage of the filtering device adopts a different filtering structure to gradually remove impurities such as suspended particles, organic matter and microorganisms in the water. This ensures that the fertigation machine can always provide high-quality irrigation water to meet the needs of crop growth and further improve the yield and quality of crops.

[0077] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
