Description

Technical Field

[0001] This invention relates to the field of irrigation and fertilization technology, specifically to a highly efficient integrated water and fertilizer irrigation and fertilization system. Background Technology

[0002] Integrated water and fertilizer management is a new model of agricultural irrigation that involves pre-dissolving fertilizer in water before irrigation. This technology applies fertilizer through the irrigation system, allowing crops to absorb nutrients while absorbing water. Typically, fertilization, performed simultaneously with irrigation, is achieved by injecting the fertilizer solution into the irrigation pipes under pressure. The fertilizer-containing irrigation water is then sprayed onto the crops or dripped into the root zone through irrigation devices (sprinklers, micro-sprinklers, and drippers). In a broader sense, it refers to the application of fertilizer after dissolving it, encompassing methods such as drenching, watering, spraying, and pipe application; it represents a new agricultural technology that integrates irrigation and fertilization. Fertilizer and water integration is an agricultural technology that utilizes a pressure system (or natural terrain gradient) to deliver soluble solid or liquid fertilizers, formulated according to soil nutrient content and the specific nutrient requirements of different crops, along with irrigation water. This solution is supplied through a controlled pipeline system, ensuring the fertilizer and water are well mixed. The resulting solution, delivered via pipes and drip emitters, forms sprinkler or drip irrigation, evenly, regularly, and quantitatively irrigating the root zone of the crops. This maintains the soil around the main root system in a loose and appropriately moist environment. Furthermore, based on the specific nutrient requirements of different crops, soil conditions, nutrient content, and the water and nutrient needs at different growth stages, the system designs different growth stages to provide water and nutrients directly to the crops in a timely, quantitative, and proportional manner. Fertilizer and water integration is a new agricultural technology that integrates irrigation and fertilization. It uses a pressure irrigation system to accurately deliver soluble solid or liquid fertilizers, formulated according to soil nutrient content and the specific nutrient requirements of the planted crops, along with irrigation water, to the root zone of the crops to meet their growth needs. In layman's terms, fertigation technology is an irrigation and fertilization technique that designs for the entire growth cycle of crops according to their needs, providing water and nutrients directly to the crops in a quantitative, timed, and proportional manner. Implementing fertigation technology requires a fixed water source with good water quality that meets the requirements of micro-irrigation, such as rivers, reservoirs, or wells, and a complete pressure irrigation system, such as drip irrigation or sprinkler irrigation. In addition to motors, pumps, filters, protectors, and water distribution pipelines, the irrigation system should also have fertilizer applicators and control and measurement equipment. Currently, fertigation technology is mainly used in greenhouses, orchards, open-field vegetables, and other crops with high economic benefits. The process of fertilizer entering the field along with irrigation water is called irrigation fertilization. That is, drip irrigation, subsurface drip irrigation, etc., simultaneously apply fertilizer accurately and evenly near the root system according to the crop's nutrient needs at each growth stage and climatic conditions, allowing it to be directly absorbed and utilized by the roots. Intelligent integrated water and fertilizer irrigation system can automatically detect, allocate and supply water and fertilizer according to the water and fertilizer requirements of different crops, as well as the soil environment and nutrient content. While improving the efficiency of irrigation water use, it also realizes the timed and quantitative control of irrigation and fertilization. It can not only save water, fertilizer and electricity, but also reduce labor input and lower labor costs.

[0003] Existing irrigation and fertilization systems typically combine main pipelines and branch pipelines to achieve large-area irrigation and fertilization operations for crops. However, the flow rate of water and fertilizer decreases as it flows further down the pipeline, making it difficult to ensure that all crops receive the same level of irrigation and fertilization treatment. This results in uneven and inefficient irrigation. To address these issues, existing equipment needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide an efficient integrated water and fertilizer irrigation and fertilization system to solve the problem mentioned in the background art. Existing irrigation and fertilization systems generally combine main pipelines and branch pipelines to realize irrigation and fertilization operations for large-area crops. However, the flow rate of water and fertilizer decreases as it flows further, making it difficult to ensure that all crops receive the same level of irrigation and fertilization treatment. This leads to uneven and inefficient irrigation effects.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency integrated water and fertilizer irrigation and fertilization system, comprising a water storage tank, a top plug threadedly connected to the top of the water storage tank, an auxiliary tumbling mechanism fixed to the bottom of the water storage tank, a squeezing mechanism rotatably connected inside the water storage tank, a water pump fixed to the bottom of the water storage tank, a pumping pipe fixed to one side of the water pump, the pumping pipe passing through one side of the water storage tank and connected to the irrigation mechanism.

[0006] Preferably, the auxiliary tumbling mechanism includes a support block, which is fixed to the inner bottom of the water storage tank. The inner side of the support block is connected to the movable rod via a first compression spring, and the first compression spring wraps around the outer side of the movable rod. The movable rod passes through the support block and is connected to the movable frame. A pressure-drawing frame is fixed to the outer side of the movable frame. A rotary valve is rotatably connected to the inner wall of the pressure-drawing frame via a spiral spring. A fixed pipe is fixed to the inner bottom of the water storage tank, and the pressure-drawing frame is slidably connected inside the fixed pipe.

[0007] Preferably, a motor is fixed to the top of the water storage tank, the extrusion mechanism includes a stirring column, and the stirring column is connected to the bottom of the motor, and an extrusion block is fixed to the outside of the stirring column.

[0008] Preferably, the irrigation mechanism includes an irrigation channel, which is connected to one side of a pumping pipe via a first connecting pipe. The first connecting pipes are evenly distributed on the water storage tank, and a post is fixed at the bottom of the irrigation channel.

[0009] Preferably, an electric telescopic column is fixed at the bottom of the irrigation channel, and the electric telescopic column passes through the bottom of the irrigation channel and is connected to the top pressure plate, which is slidably connected inside the irrigation channel.

[0010] Preferably, a first airtight channel is fixed on one side of the irrigation channel, and a first piston is slidably connected inside the first airtight channel. One side of the first piston is connected to a push plate through a connecting rod, and a slot is provided at the bottom of the connecting rod.

[0011] Preferably, a second airtight channel is fixed at the bottom of the irrigation channel, and the second airtight channel is connected to the first airtight channel through a second connecting pipe. A second piston is slidably connected inside the second airtight channel, and the second piston is connected to the inner top of the second airtight channel through a second compression spring. A pull rod is fixed at the top of the second piston, and the pull rod passes through the top of the second airtight channel and the top pressure plate. The second compression spring is wrapped around the outside of the pull rod.

[0012] Preferably, a groove is provided on one inner wall of the irrigation channel, and a limiting post is fixed in the groove. A slider is slidably connected in the groove, and the limiting post passes through the slider.

[0013] Preferably, the bottom of the slider is connected to the locking block via a connecting rope, and the locking block is engaged in the locking groove. The locking block is connected to the inner bottom of the first airtight channel via a third compression spring.

[0014] Preferably, a watering pipe is fixed on the other side of the irrigation channel, and the watering pipes are evenly distributed on the irrigation channel. A support plate is fixed inside the first end of the watering pipe, and one side of the support plate is connected to the pipe plug through a fourth compression spring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This highly efficient integrated water and fertilizer irrigation and fertilization system can achieve thorough and efficient mixing. After the water and fertilizer are fed into the storage tank, the stirring column can be used to fully mix them together. When the extrusion block rotates with the stirring column, it will squeeze the movable rod, the moving frame and the pressure frame to move as a whole. After the extrusion block leaves the movable rod, the movable rod, the moving frame and the pressure frame will automatically spring back. The pressure frame moves back and forth in the fixed pipe, and the rotary valve opens and closes repeatedly. The four fixed pipes take turns pumping water and fertilizer. The water and fertilizer tumble up and down in the storage tank, making the mixing effect more efficient and thorough.

[0017] 2. The high-efficiency integrated water and fertilizer irrigation and fertilization system can achieve uniform and efficient irrigation and fertilization. During the process of pumping water and fertilizer into the irrigation channel, the pipe plug seals the water pipe. After all the irrigation channels are filled with water and fertilizer, the top pressure plate moves up to facilitate automatic upward water pressure. Under the action of water pressure, the pipe plug moves and opens the water pipe, and water and fertilizer flow out through the water pipe, which is convenient for irrigating and fertilizing crops. This device can ensure that the amount of water and fertilizer sprayed from all water pipes is the same, making the irrigation effect more uniform and efficient.

[0018] 3. This efficient integrated water and fertilizer irrigation and fertilization system can achieve automatic water pressure. When the top pressure plate moves up and pushes the pull rod upward, the second piston moves up to extract the gas in the first airtight channel. At this time, the locking block locks the connecting rod, and the first piston does not move. When the top pressure plate pushes the slider upward, the locking block moves downward under the pulling action of the connecting rope to facilitate unlocking the connecting rod. The first piston, connecting rod and push plate move to the right as a whole to facilitate the automatic ejection of the remaining water and fertilizer in the irrigation channel.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 8 The present invention provides a technical solution: a high-efficiency water and fertilizer integrated irrigation and fertilization system, wherein a top plug 2 is threadedly connected to the top of the water storage tank 1, an auxiliary rolling mechanism 3 is fixed to the bottom of the water storage tank 1, a squeezing mechanism 5 is rotatably connected inside the water storage tank 1, a water pump 6 is fixed to the bottom of the water storage tank 1, a water pump pipe 7 is fixed to one side of the water pump 6, the water pump pipe 7 passes through one side of the water storage tank 1 and is connected to the irrigation mechanism 8.

[0030] In this embodiment, as Figure 2 , Figure 5 , Figure 7 and Figure 8As shown, the auxiliary tumbling mechanism 3 includes a support block 301, which is fixed to the inner bottom of the water storage tank 1. The inner side of the support block 301 is connected to the movable rod 303 via a first compression spring 302, and the first compression spring 302 wraps around the outer side of the movable rod 303. The movable rod 303 passes through the support block 301 and is connected to the movable frame 304. A pressure-drawing frame 305 is fixed to the outer side of the movable frame 304. A rotary valve 306 is rotatably connected to the inner wall of the pressure-drawing frame 305 via a spiral spring. A fixed pipe 307 is fixed to the inner bottom of the water storage tank 1. The pressure-drawing frame 305 is slidably connected to... When the extrusion mechanism 5 rotates and extrudes the movable rod 303 within the fixed pipe 307, the movable frame 304 and the pressure-drawing frame 305 move accordingly. At this time, the rotary valve 306 automatically closes. When the extrusion mechanism 5 leaves the movable rod 303, the movable rod 303, the movable frame 304, and the pressure-drawing frame 305 automatically spring back under the action of the first compression spring 302. The rotary valve 306 automatically opens, and the pressure-drawing frame 305 moves back and forth within the fixed pipe 307. The rotary valve 306 repeatedly opens and closes, and the fixed pipe 307 repeatedly pumps and presses the water and fertilizer, allowing the water and fertilizer to tumble up and down, making the mixing effect more efficient and thorough.

[0031] In this embodiment, as Figure 2 and Figure 7 As shown, a motor 4 is fixed to the top of the water storage tank 1, and the extrusion mechanism 5 includes a stirring column 501, which is connected to the bottom of the motor 4. An extrusion block 502 is fixed to the outside of the stirring column 501. After the water and fertilizer are fed into the water storage tank 1, the stirring column 501 can rotate under the action of the motor 4, which facilitates the thorough mixing of water and fertilizer. The extrusion block 502 extrudes the movable rod 303.

[0032] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the irrigation mechanism 8 includes an irrigation channel 801, which is connected to one side of the pumping pipe 7 via a first connecting pipe 802. The first connecting pipes 802 are evenly distributed on the water storage tank 1. A post 803 is fixed at the bottom of the irrigation channel 801. Inserting the post 803 into the soil can fix the irrigation channel 801. The water pump 6 can pump water and fertilizer from the water storage tank 1 into the irrigation channel 801. The water and fertilizer enter the irrigation channel 801 through the first connecting pipe 802, which facilitates irrigation and fertilization of crops. The evenly distributed irrigation channels 801 can make the irrigation and fertilization effect more comprehensive and uniform.

[0033] In this embodiment, as Figure 2 and Figure 3As shown, an electric telescopic column 804 is fixed at the bottom of the irrigation channel 801, and the electric telescopic column 804 passes through the bottom of the irrigation channel 801 and is connected to the top pressure plate 805. The top pressure plate 805 is slidably connected inside the irrigation channel 801. The top pressure plate 805 can move up and down under the telescopic action of the electric telescopic column 804. When the top pressure plate 805 moves up, it can push out the water and fertilizer inside the irrigation channel 801.

[0034] In this embodiment, as Figure 3 and Figure 6 As shown, a first airtight channel 806 is fixed to one side of the irrigation channel 801, and a first piston 807 is slidably connected inside the first airtight channel 806. One side of the first piston 807 is connected to the push plate 810 through a connecting rod 808. A slot 809 is provided at the bottom of the connecting rod 808. When the gas in the first airtight channel 806 is drawn out while the connecting rod 808 is locked, the air pressure in the first airtight channel 806 decreases. After the connecting rod 808 is unlocked, the connecting rod 808 and the first piston 807 will automatically move to the right, thereby driving the push plate 810 to move to the right, so as to facilitate the automatic ejection of water and fertilizer in the irrigation channel 801.

[0035] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, a second airtight channel 812 is fixed at the bottom of the irrigation channel 801, and the second airtight channel 812 is connected to the first airtight channel 806 through a second connecting pipe 811. A second piston 814 is slidably connected inside the second airtight channel 812, and the second piston 814 is connected to the inner top of the second airtight channel 812 through a second compression spring 813. A pull rod 815 is fixed at the top of the second piston 814, and the pull rod 815 passes through the top of the second airtight channel 812 and the top pressure plate 805. The second compression spring 813 is wrapped around the outside of the pull rod 815. The second connecting pipe 811 serves to connect the second airtight channel 812 and the first airtight channel 806. When the top pressure plate 805 moves upward and pushes the pull rod 815 upward, the second piston 814 moves upward, thereby drawing away the gas in the first airtight channel 806. The second compression spring 813 can assist the second piston 814 in resetting.

[0036] In this embodiment, as Figure 3 and Figure 6 As shown, a groove 816 is provided on an inner wall of the irrigation channel 801, and a limiting post 817 is fixed in the groove 816. A slider 818 is slidably connected in the groove 816. The limiting post 817 passes through the slider 818. When the top pressure plate 805 moves upward and pushes the slider 818 upward, the groove 816 and the limiting post 817 limit the slider 818.

[0037] In this embodiment, as Figure 3 and Figure 6 As shown, the bottom of the slider 818 is connected to the locking block 820 via a connecting rope 819, and the locking block 820 is engaged in the slot 809. The locking block 820 is connected to the bottom of the first airtight channel 806 via a third compression spring 821. When the top pressure plate 805 moves upward and pushes the slider 818 upward, the locking block 820 will move downward and leave the slot 809 under the pulling action of the connecting rope 819, making it easy to unlock the connecting rod 808. The first piston 807, the connecting rod 808 and the push plate 810 will move automatically to the right as a whole. When air is compressed into the first airtight channel 806, the first piston 807, the connecting rod 808 and the push plate 810 will move to the left as a whole. The locking block 820 will finally spring into the slot 809 under the supporting action of the third compression spring 821, making it easy to relock the connecting rod 808.

[0038] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a watering pipe 822 is fixed on the other side of the irrigation channel 801, and the watering pipes 822 are evenly distributed on the irrigation channel 801. A support plate 823 is fixed inside the first end of the watering pipe 822, and one side of the support plate 823 is connected to the pipe plug 825 through a fourth compression spring 824. When the water and fertilizer in the water storage tank 1 are pumped into the irrigation channel 801, the pipe plug 825 is pushed by the fourth compression spring 824, and the watering pipe 822 is in a closed state. After the entire watering pipe 822 is filled with water, the watering pipe 822 is opened. When the top pressure plate 805 pushes the water upward, the pipe plug 825 moves under the action of water pressure, the watering pipe 822 is opened, and the water and fertilizer can flow onto the crops along the watering pipe 822.

[0039] The method of use and advantages of this invention: The working process of this high-efficiency integrated water and fertilizer irrigation and fertilization system is as follows:

[0040] like Figures 1 to 8As shown: First, insert the insertion post 803 into the soil, and then introduce water and fertilizer into the water storage tank 1. The mixing post 501 and the extrusion block 502 rotate as a whole. The mixing post 501 thoroughly mixes the water and fertilizer together. When the extrusion block 502 presses against the movable rod 303, the moving frame 304, and the pressure-drawing frame 305, the rotary valve 306 automatically closes. After the extrusion block 502 leaves the movable rod 303, the movable rod 303, the moving frame 304, and the pressure-drawing frame 305 automatically spring back, and the rotary valve 306 automatically opens. As the mixing post 501 and the extrusion block 502 rotate continuously, the pressure-drawing frame 305 moves back and forth within the fixed pipe 307. The rotary valve 306 repeatedly opens and closes, and the four fixed pipes 307 alternately pump water and fertilizer, allowing the water and fertilizer to tumble up and down, facilitating efficient and thorough mixing. After the water pump 6 pumps the water and fertilizer into the pumping pipe 7, the water and fertilizer flow into the irrigation channel 801 through the first connecting pipe 802, and the pipe plug 825 is located at... In the closed state, after all irrigation channels 801 are filled with water and fertilizer, the top pressure plate 805 moves upward, thereby pushing out the water and fertilizer in the irrigation channels 801. The pipe plug 825 moves to the right and opens under the action of water pressure, and the water and fertilizer flow out through the irrigation pipe 822 to irrigate and fertilize the crops. When the top pressure plate 805 pushes the pull rod 815 upward, the second piston 814 moves upward, thereby drawing out the gas in the first airtight channel 806. The connecting rod 808 is temporarily locked, and the first piston 807 does not move. When the top pressure plate 805 continues to move upward and pushes the slider 818 upward, the locking block 820 moves downward under the pulling action of the connecting rope 819, thereby unlocking the connecting rod 808. The first piston 807, the connecting rod 808 and the push plate 810 move to the right as a whole. The push plate 810 pushes out the remaining water and fertilizer in the irrigation channel 801. When the top pressure plate 805 moves to the bottom, the locking block 820 can lock the connecting rod 808 again.

[0041] In summary, this efficient integrated water and fertilizer irrigation and fertilization system achieves the goals of thorough and efficient mixing, uniform and efficient irrigation and fertilization, and automatic water pressure, thus meeting people's usage needs.
