Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilization and irrigation technology, and in particular to a water-saving integrated water and fertilizer device. Background Technology

[0002] The fertigation system is an intelligent agricultural system that combines irrigation and fertilization. It precisely delivers soluble fertilizer to the roots of crops through pressurized pipelines, enabling simultaneous water and fertilizer management and precise control. Compared to traditional methods, it saves 30-50% of water and 20-30% of fertilizer, significantly improving resource utilization. It is suitable for various planting scenarios such as open fields, greenhouses, and orchards.

[0003] A search revealed a water and fertilizer integration device disclosed in announcement number CN222396189U, which includes multiple mixing tanks arranged in parallel. Although the device can perform fertilization and irrigation, the granular fertilizer needs to be dissolved before it can be used. The mixing is done by the mixing blades alone, which are difficult to break down quickly, resulting in low efficiency. Therefore, a water-saving water and fertilizer integration device is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where granular fertilizers need to be dissolved before use and the stirring process using a stirring blade is inefficient. Therefore, this invention proposes a water-saving integrated water and fertilizer device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water-saving fertigation device includes a frame, multiple identical mixing tanks and irrigation pipes. The top of the mixing tank is rotatably connected to a through mixing shaft, and the bottom of the mixing shaft is fixedly connected to an installation block. Multiple evenly distributed crushing mechanisms are fixedly installed around the circumference of the installation block to crush the fertilizer.

[0007] The compaction mechanism includes a mounting shaft, which is rotatably connected to one side of the mounting block. One end of the mounting shaft is fixedly connected to an inclined pressure plate. The fixing point between the mounting shaft and the pressure plate is located above one side of the pressure plate, so that the bottom end of the pressure plate remains in contact with the bottom inner wall of the mixing tank under its own weight. An inclined guide plate is fixedly connected to one side of the bottom of the pressure plate to guide the fertilizer into the bottom of the pressure plate.

[0008] As a further embodiment of this invention, a motor is fixedly connected to the top of the mixing tank, and one end of the motor output shaft is connected to the mixing shaft.

[0009] As a further embodiment of this utility model, a feed pipe and a water injection pipe are fixedly connected to the top of the mixing tank, and the feed pipe and the water injection pipe are in communication with the internal space of the mixing tank.

[0010] As a further embodiment of this utility model, a through filter cylinder is fixedly connected to one side of the mixing tank. The filter cylinder is inclined and its top is fixedly connected to the water injection pipe. Multiple through holes are opened around the circumference of the filter cylinder, and all the through holes are located inside the mixing tank. An end cap is threadedly connected to one end of the filter cylinder.

[0011] As a further embodiment of this invention, a filter screen is fixedly connected to the inner wall of the filter cartridge.

[0012] As a further embodiment of this invention, a top cover is connected to the top of the feed pipe.

[0013] As a further embodiment of this utility model, a water pump is fixedly connected to the bottom of the frame, the outlet end of the water pump is connected to the irrigation pipe through a pipe, the inlet end of the water pump is fixedly connected to a connecting pipe, and the mixing tank and the connecting pipe are both connected through pipes, and each connecting pipe is equipped with a solenoid valve and a flow meter.

[0014] As a further embodiment of this utility model, a control box is fixedly installed at the bottom of the frame, and a controller is installed inside the control box. The motor, water pump, solenoid valve and flow meter are all electrically connected to the controller.

[0015] As a further improvement of this utility model, the bottom inner wall of the mixing tank is provided with multiple extrusion grooves that work in conjunction with the pressure plate.

[0016] In this application, fertilizer is fed into the mixing tank through the feed pipe, and mixed water enters the mixing tank through the water injection pipe. During mixing, the motor is started, and the motor drives the mixing shaft to rotate, thereby dissolving the fertilizer and mixing it with the water. When the fertilizer is added, it settles to the bottom of the mixing tank. During mixing, the mixing shaft drives the mounting block to rotate, and the mounting block drives the pressure plate to rotate through the mounting shaft. The surface of the pressure plate faces the water. At the same time, since the mounting shaft is located slightly above the side of the pressure plate, the water pressure can keep the bottom of the pressure plate in contact with the bottom of the mixing tank during rotation. Under the action of the guide plate, the fertilizer enters below the pressure plate, thereby crushing the granular fertilizer, improving the dissolution and mixing efficiency, and facilitating use. At the same time, the extrusion groove set on the inner wall of the bottom of the mixing tank cooperates with the pressure plate to improve the crushing effect of the fertilizer. During irrigation, irrigation water is directly delivered to the soil and field through the irrigation pipe. At the same time, the water pump is started, which delivers the dissolved fertilizer in the mixing tank to the field. With the multiple water outlets of the irrigation pipe, precise fertilization and irrigation can be achieved.

[0017] Beneficial effects: In this utility model, the water-saving fertigation device, by installing a pressure plate inside the mixing tank, uses water pressure to keep the bottom of the pressure plate in contact with the bottom of the mixing tank, and under the action of the guide plate, the fertilizer enters under the pressure plate, thereby crushing the granular fertilizer, improving the dissolution and mixing efficiency, and making it convenient to use;

[0018] In this utility model, the water-saving integrated water and fertilizer device has a filter cartridge installed at the bottom of the water injection pipe. This allows the water source to be filtered through the filter cartridge and filter screen when water is added, preventing foreign objects from entering the mixing tank and damaging the electrical equipment, thus improving the safety of use.

[0019] In this invention, water pressure is used to keep the bottom of the pressure plate in contact with the bottom of the mixing tank, and the fertilizer is allowed to enter under the pressure plate under the action of the guide plate, thereby crushing the granular fertilizer, improving the dissolution and mixing efficiency, and making it convenient to use. At the same time, the water source can be filtered through the filter cartridge and filter screen to prevent foreign objects from entering the mixing tank and damaging the electrical equipment, thereby improving the safety of use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In one embodiment: Refer to Figures 1-4A water and fertilizer integration device includes: a frame 1, multiple identical mixing tanks 3 and irrigation pipes 4. Brake-operated casters can be installed at the bottom of the frame 1 for easy movement. The irrigation pipes 4 extend to the field and can be used in conjunction with drip irrigation for precise irrigation. A through mixing shaft 13 is rotatably connected to the top of the mixing tank 3. An installation block 14 is fixedly connected to the bottom of the mixing shaft 13. Multiple evenly distributed crushing mechanisms are fixedly installed on the circumference of the installation block 14 to crush the fertilizer.

[0027] The compaction mechanism includes a mounting shaft 18, which is rotatably connected to one side of the mounting block 14. One end of the mounting shaft 18 is fixedly connected to an inclined pressure plate 19. The fixing point between the mounting shaft 18 and the pressure plate 19 is located above one side of the pressure plate 19, so that the bottom end of the pressure plate 19 remains in contact with the bottom inner wall of the mixing tank 3 under its own weight. An inclined guide plate 20 is fixedly connected to one side of the bottom of the pressure plate 19 to guide the fertilizer into the bottom of the pressure plate 19.

[0028] like Figure 3 As shown, during stirring, the stirring shaft 13 drives the mounting block 14 to rotate counterclockwise. The mounting block 14 drives the pressure plate 19 to rotate counterclockwise via the mounting shaft 18. When the pressure plate 19 rotates counterclockwise, the upper surface of the pressure plate 19 faces the water. The water resistance is applied to the upper surface of the pressure plate 19, thereby generating a downward force, so that the bottom of the pressure plate 19 contacts the bottom inner wall of the mixing tank 3, so that the material is crushed when it passes through the bottom of the pressure plate 19.

[0029] like Figure 4 As shown, in order to ensure that the bottom of the pressure plate 19 is always subjected to a downward force during counterclockwise rotation, the mounting shaft 18 is positioned on the upper side of the end of the pressure plate 19. This allows the pressure plate 19 to also tend to rotate downwards under gravity and press against the bottom inner wall of the mixing tank 3. During rotation, water pressure can maintain the bottom of the pressure plate 19 in contact with the bottom of the mixing tank 3. An upwardly curved guide plate 20 is provided on the side of the pressure plate 19 facing the rotation direction. When the pressure plate 19 contacts the bottom of the mixing tank 3, the guide plate 20 forms an opening with the bottom inner wall of the mixing tank 3, allowing the material to enter between the guide plate 20 and the bottom inner wall of the mixing tank 3. Under the action of the guide plate 20, the fertilizer enters below the pressure plate 19, thereby crushing the granular fertilizer and improving the dissolution and mixing efficiency.

[0030] This application can be used in the field of agricultural fertilization and irrigation, as well as in other fields applicable to this application.

[0031] In another embodiment: Reference Figures 1-4 A water-saving integrated water and fertilizer device is applied to the field of agricultural fertilization and irrigation.

[0032] In this invention, a motor 21 is fixedly connected to the top of the mixing tank 3. One end of the output shaft of the motor 21 is connected to the mixing shaft 13. When the motor 21 is started, the motor 21 drives the mixing shaft 13 to rotate, thereby dissolving the fertilizer and mixing it with water.

[0033] In particular, the top of the mixing tank 3 is fixedly connected to a feed pipe 7 and a water injection pipe 8. The feed pipe 7 and the water injection pipe 8 are used to add water and fertilizer, respectively. One end of the feed pipe 7 is connected to the internal space of the mixing tank 3, and the other end is connected to a material tank containing fertilizer. The material in the material tank is pumped into the mixing tank 3 through the feed pipe 7 by a pumping mechanism. One end of the water injection pipe 8 is connected to the internal space of the mixing tank 3, and the other end is connected to a water source. Water from the water source can be injected into the mixing tank 3 through the water injection pipe 8 by gravity, or the water source can be introduced into the mixing tank 3 through the water injection pipe 8 by a pumping component.

[0034] Furthermore, in order to measure the injected water and fertilizer, a valve and a flow meter (not shown in the figure) are installed on the feed pipe 7, and a valve and a flow meter (not shown in the figure) are installed on the water injection pipe 8 near the mixing tank 3. The mixing ratio is controlled by controlling the amount of water and fertilizer fed into the mixing tank 3.

[0035] It should be noted that a through filter cylinder 9 is fixedly connected to one side of the mixing tank 3. The filter cylinder 9 is inclined and its top is fixedly connected to the water injection pipe 8. Multiple through holes 10 are opened around the circumference of the filter cylinder 9. All the through holes 10 are located inside the mixing tank 3. One end of the filter cylinder 9 is threadedly connected to an end cap 12. A filter screen 11 is fixedly connected to the inner wall of the filter cylinder 9. The water source can be filtered through the filter cylinder 9 and the filter screen 11 to prevent foreign objects from entering the mixing tank 3 and damaging the electrical equipment, thereby improving the safety of use. The foreign objects can be discharged by opening the end cap 12.

[0036] In actual use, the water input from the water inlet pipe 8 is first sent into the filter cylinder 9. When water needs to be released into the mixing tank 3, the end of the filter cylinder 9 is sealed by the end cap 12. The water entering the filter cylinder 9 flows into the mixing tank 3 after passing through the filter screen 11, and foreign objects in the water source are filtered out by the filter screen 11. When there are many foreign objects in the filter cylinder 9, the foreign objects can be cleaned by opening the end cap 12.

[0037] In this invention, the top of the feed pipe 7 is threaded with a top cover. After feeding, the top cover is reset to keep the inside of the mixing tank 3 clean.

[0038] In particular, a water pump 6 is fixedly connected to the bottom of the frame 1. The outlet of the water pump 6 is connected to the irrigation pipe 4 through a pipe. The inlet of the water pump 6 is fixedly connected to a connecting pipe 5. The mixing tank 3 and the connecting pipe 5 are connected through pipes, and each connecting pipe is equipped with a solenoid valve 16 and a flow meter 17. During irrigation, the irrigation water is directly delivered to the soil and field through the irrigation pipe 4. At the same time, the water pump 6 is started, which in turn delivers the dissolved fertilizer in the mixing tank 3 to the field. With the help of multiple water outlets of the irrigation pipe 4, precise fertilization and irrigation can be achieved.

[0039] It should be noted that a control box 2 is fixedly installed at the bottom of the frame 1. The control box 2 contains a controller. The motor 21, water pump 6, solenoid valve 16, and flow meter 17 are all electrically connected to the controller. The motor 21, water pump 6, solenoid valve 16, and flow meter 17 are connected to an external power supply. When using the machine, the operator inputs preset parameters into the controller to automate the fertilization process. For example, by inputting a preset amount of fertilizer into the controller, the controller controls the motor 21 and water pump 6 to power on and open the solenoid valve 16. At this time, the flow meter 17 counts the flow rate and feeds the flow data back to the controller. When the flow rate data of the flow meter 17 reaches the preset value, the controller controls the motor 21 and water pump 6 to stop and controls the solenoid valve 16 to close, thus completing the fertilization action. It should be noted that the controller's inherent functions are to receive preset data from the operator, receive flow data from the flow meter 17, and start and stop the motor 21 and water pump 6 based on the flow data and preset data.

[0040] like Figure 3 As shown in the figure, in this utility model, the bottom inner wall of the mixing tank 3 is provided with multiple extrusion grooves 15 that work in conjunction with the pressure plate 19. The extrusion grooves 15 and the pressure plate 19 on the bottom inner wall of the mixing tank 3 can improve the crushing effect of fertilizer. Specifically, the extrusion grooves 15 are strip-shaped grooves, and the extension direction of the strip-shaped grooves is radially arranged from the center of the bottom inner wall of the mixing tank 3 to the circumference. The cross-sectional size of the extrusion grooves 15 is smaller than the size of the fertilizer. On the one hand, it can allow a portion of a single fertilizer particle to enter the extrusion groove 15, thereby limiting the fertilizer. When the pressure plate 19 crushes it, it prevents the fertilizer from flying out, thereby improving the crushing effect of fertilizer.

[0041] It should be noted that those skilled in the art should understand that the composition, working principle, and electrical connection method of the control box 2, motor 21, solenoid valve 16, and flow meter 17 are all conventional technical means in this field. The specific implementation of these standard components can be reasonably selected and configured according to the needs of the actual application scenario, and their specific implementation methods are common knowledge to those skilled in the art. Therefore, this specification will not repeat the description of this part of the technical features.

[0042] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
