[0043] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0044] The present invention provides a fertilizer dissolving and storage container, a fertilizer dissolving system, and a fertilizer application system. The fertilizer dissolving and storage container can be used in the fertilizer dissolving system and the fertilizer application system, which will be described in detail below.

[0045] refer to Figures 1 to 3 The fertilizer storage container includes a flexible bag 1, a support structure 2 and a fertilizer spraying pipe 3. The support structure 2 and the flexible bag 1 are detachably connected. The support structure 2 supports the flexible bag 1 to form a receiving cavity 10 with a top opening. The fertilizer spraying pipe 3 is located at the bottom of the flexible bag 1 and is provided with spray holes 30.

[0046] The flexible bag 1 of this embodiment is provided with a fertilizer spraying pipe 3 at its bottom. Fertilizer liquid can be sprayed out through the spraying pipe 3. The fertilizer liquid in the spraying pipe 3 has a certain pressure, which can make the fertilizer liquid in the containing cavity 10 spray out from the spray hole 30 to accelerate the dissolution of solid fertilizer. No additional stirring mechanism is required, which helps to reduce the overall weight of the container. Moreover, since the flexible bag 1 is supported by the support structure 2, after use, the support structure 2 can be separated from the flexible bag 1, and then the flexible bag 1 can be folded. The folded flexible bag 1 is small in size, which is convenient for carrying, transporting and storing. When it is needed for reuse, the support structure 2 can be connected to the flexible bag 1 and the flexible bag 1 can be opened again using the support structure 2. In addition, the flexible bag 1 integrates the functions of dissolving fertilizer and storing fertilizer. After the fertilizer is dissolved, the fertilizer liquid can be directly stored in the containing cavity 10, thereby reducing the number of containers. A single container is convenient for transportation and installation.

[0047] The fertilizer spraying pipe 3 can be located at the bottom of the flexible bag 1 or at the side of the flexible bag 1. When the fertilizer spraying pipe 3 is located at the bottom of the flexible bag 1, it can ensure that the solid fertilizer at the bottom of the receiving cavity 10 can move under the action of the fertilizer liquid sprayed from the spray hole 30, thereby achieving a better fertilizer dissolving effect. Taking the fertilizer spraying pipe 3 located at the bottom of the flexible bag 1 as an example, the bottom of the flexible bag 1 is provided with multiple restraining members 31, and the fertilizer spraying pipe 3 is fixed to the bottom of the flexible bag 1 by the restraining members 31.

[0048] Optionally, the restraint member 31 is a flexible restraint strap, with both ends connected to the bottom of the flexible bag 1 and forming restraint openings. The fertilizer spraying pipe 3 passes through the restraint openings, thus fixing the fertilizer spraying pipe 3 to the bottom of the flexible bag 1. Of course, the restraint member 31 can also be a buckle, which is fixed to the bottom of the flexible bag 1 by heat fusion or adhesive. Here, the form of the restraint member 31 is not limited.

[0049] The fertilizer spraying tube 3 can be either a flexible tube or a rigid tube. When the fertilizer spraying tube 3 is a flexible tube, it can be made of plastic or polymer materials. The fertilizer spraying tube 3 can be integrally molded with the flexible bag 1, or the fertilizer spraying tube 3 can be heat-fused to the bottom of the flexible bag 1. In this case, the fertilizer spraying tube 3 and the flexible bag 1 can be folded and stored at the same time without having to remove the fertilizer spraying tube 3 from the flexible bag 1, reducing the number of operation steps during use and making it more convenient to use, carry, and transport. When the flexible tube is filled with liquid, it will expand. The flexible restraint band can limit the flexible tube and prevent it from deforming.

[0050] When the fertilizer spraying pipe 3 is a rigid pipe, it can be a metal pipe or a rigid plastic pipe. The rigid pipe and the flexible bag 1 can be detachably connected or fixedly connected. For example, when the rigid pipe and the flexible bag 1 are detachably connected, the rigid pipe can be removed from the constraint port of the constraint member 31. When it is used again, the rigid pipe can be inserted into the constraint port. The flexible constraint band can limit the rigid pipe and keep the position of the rigid pipe stable.

[0051] The flexible bag 1 is made of a flexible material, such as plastic or polymer. The flexible bag 1 must be leak-proof and have good corrosion resistance and abrasion resistance. The flexible bag 1 can be supported and unfolded by the support structure 2 to form a receiving cavity 10. The shape of the receiving cavity 10 is changed by the form of the support structure 2; the receiving cavity 10 can be a cylindrical cavity, a regular polygonal cavity, or an irregularly shaped cavity. In this embodiment, the following description uses a cylindrical cavity 10 as an example.

[0052] The flexible bag 1 has a circulation inlet 12 and a circulation outlet 13 on its side wall, which are connected to the containing cavity 10. Both the circulation outlet 13 and the circulation inlet 12 are connected to the circulation pipe 4 outside the containing cavity 10. One end of the circulation inlet 12 is also connected to the fertilizer spraying pipe 3, and the fertilizer in the containing cavity 10 can be circulated and dissolved through the circulation pipe 4.

[0053] The fertilizer spraying pipe 3 can be fixedly connected to the side wall of the flexible bag 1 or integrally formed, or it can be located inside the receiving cavity 10. A first connector 121 can be installed at the circulation inlet 12 of the flexible bag 1. The first connector 121 can be a straight connector. The first end of the first connector 121 is located in the receiving cavity 10 and connected to the end of the fertilizer spraying pipe 3. The second end of the first connector 121 is located outside the flexible bag 1. The second end of the first connector 121 can serve as the circulation inlet 12 and communicate with the circulation pipe 4. Similarly, a pipe connector can also be provided at the circulation outlet 13. The first end of the pipe connector communicates with the inside of the receiving cavity 10, and the second end of the pipe connector is located outside the flexible bag 1 and connected to the circulation pipe 4.

[0054] The circulation pipeline 4 includes a fertilizer outlet pipe 40 and a fertilizer inlet pipe 41. One end of the fertilizer inlet pipe 41 is connected to the first connector 121 or the circulation inlet 12, and the other end of the fertilizer inlet pipe 41 is connected to the liquid outlet end of the circulation pump 5. One end of the fertilizer outlet pipe 40 is connected to the circulation outlet 13 or the pipe connector at the circulation outlet 13, and the other end of the fertilizer outlet pipe 40 is connected to the liquid inlet end of the circulation pump 5. The fertilizer solution is pressurized and pumped into the fertilizer spraying pipe 3 by the circulation pump 5, and then sprayed back into the accommodating cavity 10 through the spray hole 30 to agitate the fertilizer solution in the accommodating cavity 10 and achieve accelerated dissolution of the fertilizer.

[0055] Since there are undissolved fertilizers or impurities in the fertilizer solution, in order to avoid clogging the fertilizer spraying pipe 3 or the circulation pipe 4, a first filter device 131 is provided inside the circulation outlet 13 to filter out solid fertilizers or impurities.

[0056] Optionally, refer to Figure 4 The first filtration device 131 includes a filter screen 1311, a filter 1312, and a filter screen mounting base 1313. The filter 1312 is installed on the filter screen 1311. The filter screen mounting base 1313 is a pipe connected to the circulation outlet 13. The filter 1312 is connected to and fixed to the filter screen mounting base 1313. The filter screen is set outside the filter 1312 and is used to filter large-diameter fertilizer particles or impurities. The filter 1312 is at a certain height from the bottom wall of the receiving cavity 10, which can reduce the probability of fertilizer entering the filter 1312 during stirring. The fertilizer solution in the receiving cavity 10 enters the circulation fertilizer outlet pipe 40 from the filter 1312 through the filter screen mounting base 1313.

[0057] To facilitate the injection of external water into the receiving cavity 10, the side wall of the flexible bag 1 is also provided with a water inlet 11 communicating with the receiving cavity 10. The water inlet 11 is used to inject water into the receiving cavity 10. Water can be directly injected through the water inlet 11, or a second connector 111 can be installed at the water inlet 11. The second connector 111 can be a straight connector, with its first end located in the receiving cavity 10 and its second end located outside the flexible bag 1. The second end of the second connector 111 can serve as the water inlet 11, connecting to an external water supply pipe to inject water into the receiving cavity 10. Optionally, water can also be injected directly from the top opening of the flexible bag 1. Compared to injecting water from the side opening of the flexible bag 1, injecting water from the top opening requires pumping the water to a higher position, which consumes more electricity.

[0058] Optionally, considering that a larger flow rate is required during the fertilizer solution circulation and dissolution process to improve the fertilizer dissolution efficiency, the second diameter of the second connector 111 can be set to be smaller than the first diameter of the first connector 121.

[0059] In this embodiment of the invention, the water inlet 11 is located on the side wall of the flexible bag 1 and near the bottom. It can both impact the fertilizer solution in the containing cavity 10, accelerating the dissolution rate, and also serve as a fertilizer suction port, allowing the stirred fertilizer solution to be drawn out for application. When the water inlet 11 is also used as a fertilizer suction port, a second filter device 112 can be installed inside the water inlet 11 to filter out any fertilizer particles, crystals, or impurities that may be present in the fertilizer solution, preventing them from entering the water-fertilizing pipeline 60 and causing blockage of the fertilizer applicator 7 and control valve 61 on the pipeline 60. The structure of the second filter device 112 can be the same as the first filter device 131, and the second filter device 112 is connected to the second connector 111. Optionally, the fertilizer suction port can also be a different orifice from the water inlet 11.

[0060] Optionally, the first end of the second connector 111 is an elbow structure. The elbow structure causes the first end port of the second connector 111 to be set along the tangential direction of the side wall of the flexible bag 1. When external water is sprayed out from the second connector 111 along the tangential direction of the side wall of the flexible bag 1, it can apply an initial momentum along the tangential direction to the liquid in the accommodating cavity 10, so that the water flow can accelerate along the circumferential wall of the flexible bag 1, causing the fertilizer solution in the accommodating cavity 10 to form a vortex, thereby accelerating the dissolution efficiency of the fertilizer.

[0061] The number of fertilizer spraying pipes 3 can be one or more. When there is one fertilizer spraying pipe 3, it can be arranged along the diameter of the flexible bag 1 or distributed in a circle around the circumference of the flexible bag 1. When there are multiple fertilizer spraying pipes 3, each fertilizer spraying pipe 3 includes a first fertilizer spraying branch pipe 32 and at least one second fertilizer spraying branch pipe 33. One end of the first fertilizer spraying branch pipe 32 is connected to the circulation inlet 12, and the other end of the first fertilizer spraying branch pipe 32 is connected to one end of the second fertilizer spraying branch pipe 33. The other end of the second fertilizer spraying branch pipe 33 extends to the outside of the flexible bag 1, and the end of the second fertilizer spraying branch pipe 33 extending to the outside of the flexible bag 1 can serve as a drain outlet 34.

[0062] Because fertilizer may settle inside the spray pipe 3 during the circulating fertilizer dissolution process, a drain port 34 is provided to prevent clogging of the spray pipe 3. The drain port 34 is sealed with a plug most of the time to prevent fertilizer solution from leaking out of the drain port 34. When it is necessary to inspect or flush the spray pipe 3, the plug can be removed from the drain port 34 to check whether there is fertilizer crystal blockage in the spray pipe 3, or the spray pipe 3 can be flushed with clean water. After inspection or flushing, the drain port 34 is plugged again with the plug.

[0063] Optionally, when the ends of the fertilizer spraying pipe 3 are all located inside the accommodating cavity 10, a detachable connector can be used to connect to the ends of the fertilizer spraying pipe 3, and one end of the detachable connector can be connected to the fertilizer spraying pipe 3, while the other end of the detachable connector is located outside the flexible bag 1. The end of the detachable connector located outside the flexible bag 1 can be used as a drain outlet 34. In this way, the detachable connector can also be removed from the flexible bag 1 to replace or disassemble the fertilizer spraying pipe 3.

[0064] When there are multiple fertilizer spraying pipes 3, there can be multiple ways to arrange the fertilizer spraying pipes 3. For example, multiple fertilizer spraying pipes 3 can be distributed radially along the accommodating cavity 10, so that one end of each fertilizer spraying pipe 3 is located in the middle of the flexible bag 1, and the other end faces the side wall of the flexible bag 1.

[0065] A multi-port connector 35 is provided in the central area of ​​the accommodating cavity 10. Multiple fertilizer spraying pipes 3 are connected through the multi-port connector 35. The multiple fertilizer spraying pipes 3 are distributed around the multi-port connector 35 as the center, so that spray holes 30 are distributed in various positions in the accommodating cavity 10, which can make the solid fertilizer in various positions in the accommodating cavity 10 dissolve evenly.

[0066] Multiple spray holes 30 are provided on multiple fertilizer spraying pipes 3. The multiple spray holes 30 are located on the side wall of the fertilizer spraying pipe 3 and are perpendicular to the fertilizer spraying pipe 3, so that the fertilizer liquid is sprayed out from the spray holes 30 in the tangential direction. The tangential direction refers to the tangential direction of the circle with the center of the multi-port connector 35 as the center. In this way, the circulating fertilizer liquid sprayed out from the spray holes 30 can stir the fertilizer liquid in the accommodating cavity 10 to move in a vortex, thereby accelerating the dissolution speed of solid fertilizer and improving fertilizer dissolution efficiency.

[0067] Furthermore, the diameter of the multiple nozzles 30 on each fertilizer spraying pipe 3 gradually increases from the first end to the second end. The first end is the end of the fertilizer spraying pipe 3 closest to the multi-port connector 35, and the second end is the end of the fertilizer spraying pipe 3 furthest from the multi-port connector 35. On the one hand, the second end is closer to the inner wall edge of the fertilizer storage container's cavity 10. The nozzles 30 near the center of the cavity 10 are set to be smaller, while the nozzles 30 near the inner wall edge of the cavity 10 are set to be larger. Since the distance between the fertilizer spraying pipes 3 near the center of the cavity 10 is close, and the distance between the fertilizer spraying pipes 3 near the inner wall edge of the cavity 10 is far, by setting different nozzle sizes, the water flow rate at different positions in the cavity 10 can be adjusted to ensure a uniform water flow rate in the fertilizer storage container. On the other hand, users usually pour solid fertilizer into the edge of the fertilizer storage container. Increasing the size of the nozzles 30 at the inner wall edge of the cavity 10 can ensure the overall uniformity of fertilizer dissolution.

[0068] The flexible bag 1 needs to be expanded by the support structure 2 to form the receiving cavity 10. The support structure 2 can take many forms. It can be an existing frame on the market or a frame that can be designed by oneself.

[0069] As an example, refer to Figure 5 In this embodiment, the support structure 2 includes pipe fittings 20, connecting joints 21, and feet 22. Pipe fittings 20 further include horizontal pipes 201 and vertical pipes 202. Horizontal pipes 201 are arranged horizontally along the accommodating cavity 10, and vertical pipes 202 are arranged vertically along the accommodating cavity 10. There are multiple horizontal pipes 201, vertical pipes 202, connecting joints 21, and feet 22. Multiple tubular straps 14 are provided along the top edge of the flexible bag 1. Some horizontal pipes 201 are inserted between the multiple tubular straps 14. Adjacent horizontal pipes 201 are connected by connecting joints 21 to open the top of the flexible bag 1. Vertical pipes 202 are arranged vertically along the accommodating cavity 10. Multiple pipe fitting restraint straps 15 are provided on the sidewall of the flexible bag 1. The two ends of the multiple pipe fitting restraint straps 15 are connected to the flexible bag 1 and form perforations. At least some vertical pipes 202 are inserted through the perforations of the pipe fitting restraint straps 15, thereby supporting the flexible bag 1 in the vertical direction. The horizontal tube 201 and the vertical tube 202 are connected as a whole by a connecting joint 21. The connecting joint 21 can be a tee joint, with the two horizontal tubes 201 inserted into the two ends of the tee joint and the vertical tube 202 inserted into the other end of the tee joint. Optionally, tubing straps 14 can also be provided on the side walls and bottom edges of the flexible bag 1 to facilitate the connection of the fittings 20.

The water pump delivers water to the main water pipe 6, and then, with the control valve 61 open, delivers the liquid through the water injection and fertilizer application pipe 60 to the receiving cavity 10. The control valve 61 can control the opening and closing of the main water pipe 6 and the receiving cavity 10, so that when the control valve 61 is open, water from the main water pipe 6 can be injected into the receiving cavity 10.

[0075] To dissolve solid fertilizer, control valve 61 can be opened to deliver water from the main water pipe 6 through the water injection and fertilizer application pipe 60 to the accommodating cavity 10, so as to dissolve the solid fertilizer in the fertilizer dissolving and storage container.

[0076] To improve fertilizer dissolving efficiency, the circulation pump 5 can be turned on to pump the fertilizer solution in the fertilizer storage container to the fertilizer outlet pipe 40, and then transport it to the fertilizer spraying pipe 3 through the fertilizer inlet pipe 41. The fertilizer solution in the fertilizer spraying pipe 3 has a certain pressure and can be sprayed out from the spray hole 30. The sprayed fertilizer solution has a force on the fertilizer solution in the fertilizer storage container, causing the fertilizer solution to flow in the fertilizer storage container, thereby improving fertilizer dissolving efficiency. No additional stirring device is required.

[0077] Once the solid fertilizer has dissolved, the fertilizer solution in the fertilizer storage container can be used for fertilization.

[0078] refer to Figure 7 The present invention also provides a fertilization system, including a fertilizer applicator 7 and the above-mentioned fertilizer dissolving system. A water injection and fertilizer application pipe 60 is provided between the main water pipe 6 and the water inlet 11 of the accommodating cavity 10. A control valve 61 and the fertilizer applicator 7 are located in the water injection and fertilizer application pipe 60, and the fertilizer applicator 7 is located between the control valve 61 and the main water pipe 6. The fertilizer applicator 7 is used to transport the dissolved fertilizer solution from the accommodating cavity 10 to the main water pipe 6, and then transport the fertilizer solution to the farmland area that needs to be irrigated and fertilized through the main water pipe 6.

[0079] When fertilization is needed, the control valve 61 and the fertilizer applicator 7 can be opened to fertilize. By setting up the water injection and fertilization pipeline 60, water can be injected into the fertilizer storage container and fertilizer solution can be drawn from the fertilizer storage container for fertilization. The system has a simple structure and can save costs.

[0080] Alternatively, a separate fertilizer suction port can be provided on the flexible bag 1, which is connected to the fertilizer suction pipe. The fertilizer applicator 7 is installed on the fertilizer suction pipe. In this case, fertilizer suction and water injection do not use the same pipe.
