Description

Technical Field

[0001] This application relates to the field of agricultural equipment technology, specifically a multifunctional integrated water and fertilizer device. Background Technology

[0002] The fertigation system is a modern agricultural device that integrates irrigation and fertilization. It uses a pressure system (or natural terrain drop) to deliver soluble solid or liquid fertilizers, mixed with irrigation water according to the soil nutrient content and the fertilizer requirements and characteristics of the crop, evenly and accurately to the root zone of the crop through a pipeline system.

[0003] Currently, integrated water and fertilizer systems typically use an external pipe to input external water into the system and mix it with fertilizer. However, the external water may contain impurities, and the existing external pipes are not designed with a filtration structure. After the impurities enter the water and fertilizer machine and are mixed, they can easily lead to uneven water output from the irrigation device, affecting the crop's absorption of water and fertilizer. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and propose a multifunctional integrated water and fertilizer device to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a multifunctional integrated water and fertilizer device, including a water and fertilizer machine. An external pipe is fixedly connected to the water and fertilizer machine. An annular groove is formed at the end of the external pipe away from the water and fertilizer machine. A filter tube is detachably installed at the end of the external pipe near the annular groove through a fastening and holding mechanism. An annular plate is provided at the end of the filter tube near the annular groove, and the annular plate is movably inserted into the annular groove. A filter screen is provided inside the filter tube. A corrugated pipe is fixedly connected to the end of the filter tube away from the external pipe. A connector head is fixedly connected to the end of the corrugated pipe away from the filter tube. An angle lifting mechanism is provided outside the connector head.

[0006] Preferably, the fastening and holding mechanism includes a support platform fixedly connected to the outer surface of the water and fertilizer machine. A platform shaft is fixedly inserted through the inner side of the support platform, and a bracket is slidably connected to the outer surface of the platform shaft. A rubber pad is provided on the arc-shaped inner side of the bracket. The fastening mechanism allows for flexible disassembly and assembly of the filter tube, thereby quickly cleaning the impurities accumulated on the filter screen and reinstalling it.

[0007] Preferably, the top of the card holder is movably provided with a threaded rod, and both ends of the threaded rod are threaded with nuts.

[0008] Preferably, the angle lifting mechanism includes a fixed shaft fixedly connected to the outer surface of the support platform, an electric actuator rotatably connected to the outer surface of the fixed shaft, and a concave plate fixedly connected to the output end of the electric actuator.

[0009] Preferably, a plate shaft is fixedly inserted through the inner side of the concave plate, and a drive plate is rotatably connected to the outer surface of the plate shaft. A guide shaft is rotatably connected to the drive plate away from the plate shaft. The angle of the pipe head can be adjusted by the angle lifting mechanism. The flexibly adjustable pipe head can better adapt to stress changes at the pipe connection.

[0010] Preferably, a swing plate is rotatably connected to the outer surface of the guide shaft, and a rotating shaft is rotatably connected to the inner surface of the support platform. One end of the rotating shaft is fixedly connected to the end of the swing plate away from the guide shaft. A sleeve is provided on the rotating shaft, wherein the connecting pipe head passes through the sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This multi-functional integrated water and fertilizer device filters out most impurities in the water during the process of water flowing into the water and fertilizer machine. This prevents impurities from entering the machine and ensures the purity of the liquid during the water and fertilizer mixing process. It also prevents impurities from interfering with fertilizer dissolution or clogging the mixing system. The liquid flowing through the drippers, sprinklers, and other irrigation devices is cleaner. With improved water uniformity from the irrigation devices, the distribution of water and fertilizer in the crop root zone is more balanced, significantly reducing the risk of clogging.

[0012] 2. This multi-functional integrated water and fertilizer device can indirectly adjust the external connection angle of the external pipe through the angle lifting mechanism. The corrugated pipe can connect the water source and the water and fertilizer machine more smoothly, avoiding pipe bending or twisting caused by improper angle. This flexible adjustable connector can better adapt to stress changes at the pipe connection, reduce joint loosening or leakage caused by mismatched angles, and ensure the stability and safety of water and fertilizer delivery.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-4 A multifunctional integrated water and fertilizer device includes a water and fertilizer machine 1. An external pipe 2 is fixedly connected to the water and fertilizer machine 1. An annular groove 3 is opened at the end of the external pipe 2 away from the water and fertilizer machine 1. A filter tube 4 is detachably installed at the end of the external pipe 2 near the annular groove 3 through a fastening and holding mechanism. An annular piece 5 is provided at the end of the filter tube 4 near the annular groove 3, and the annular piece 5 is movably inserted into the annular groove 3. A filter screen 6 is provided inside the filter tube 4. A corrugated pipe 13 is fixedly connected to the end of the filter tube 4 away from the external pipe 2. The corrugated pipe 13 can be flexibly bent to a certain extent while ensuring good connection sealing. A connector head 14 is fixedly connected to the end of the corrugated pipe 13 away from the filter tube 4. An angle lifting mechanism is provided on the outside of the connector head 14.

[0017] Through the above technical solution, during the use of the device, external water is transported to the corrugated pipe 13 through the connector 14, and then to the water fertilizer machine 1 through the filter pipe 4 and the external connector 2. During this period, the filter screen 6 in the filter pipe 4 can filter impurities in the water source, and the filter pipe 4 can be flexibly disassembled and assembled through the fastening and holding mechanism so as to clean the impurities remaining on the filter screen 6.

[0018] Specifically, the fastening and holding mechanism includes a support platform 7 fixedly connected to the outer surface of the water and fertilizer machine 1, a platform shaft 8 fixedly passing through the inner side of the support platform 7, a card holder 9 slidably connected to the outer surface of the platform shaft 8, and a rubber pad 10 provided on the arc-shaped inner side of the card holder 9.

[0019] Through the above technical solution, the rubber pad 10 is designed so that the two sets of clamps 9 can clamp the filter tube 4 more stably and safely during the process of the two sets of clamps approaching each other, and reduce the clamping damage to the surface of the filter tube 4.

[0020] Specifically, the top of the card holder 9 is movably fitted with a threaded rod 11, and both ends of the threaded rod 11 are threaded with nuts 12.

[0021] With the above technical solution, both ends of the end threaded rod 11 are designed with threads. When the nut 12 is tightened, it can be moved axially along the end threaded rod 11, thereby gradually moving closer to the two brackets 9.

[0022] Specifically, the angle lifting mechanism includes a fixed shaft 15 fixedly connected to the outer surface of the support platform 7, an electric actuator 16 rotatably connected to the outer surface of the fixed shaft 15, and a concave plate 17 fixedly connected to the output end of the electric actuator 16.

[0023] Through the above technical solution, the design of the fixed shaft 15 is to cooperate with the electric push rod 16, because the electric push rod 16 will have a certain angle deflection during the process of pushing and pulling the drive plate 19 through the concave plate 17 and the plate shaft 18.

[0024] Specifically, a plate shaft 18 is fixedly inserted through the inner side of the concave plate 17, a drive plate 19 is rotatably connected to the outer surface of the plate shaft 18, and a guide shaft 20 is rotatably connected to the drive plate 19 away from the plate shaft 18.

[0025] Through the above technical solution, during the process of being pushed and pulled, the two ends of the drive plate 19 will rotate along the plate shaft 18 and the guide shaft 20 respectively, and will deflect itself.

[0026] Specifically, a swing plate 21 is rotatably connected to the outer surface of the guide shaft 20, and a rotating shaft 22 is rotatably connected to the inner surface of the support platform 7. One end of the rotating shaft 22 is fixedly connected to the end of the swing plate 21 away from the guide shaft 20, and a sleeve 23 is provided on the rotating shaft 22.

[0027] Through the above technical solution, the drive plate 19 will drive the swing plate 21 through the guide shaft 20 during the deflection process, so that the swing plate 21 will make a certain angle of circular motion around the rotating shaft 22 as the center. During this period, the rotating shaft 22 will rotate synchronously, and the sleeve 23 is sleeved on the outside of the connector head 14.

[0028] Working Principle: During use, external water is introduced into the corrugated pipe 13 through the connector 14, then filtered by the filter screen 6 inside the filter pipe 4 (removing most impurities), and finally enters the water-fertilizer 1 through the external connector 2. Soluble solid or liquid fertilizers, prepared according to soil nutrient content and crop nutrient requirements, are mixed with irrigation water and delivered evenly and accurately to the crop root zone through the pipeline system. The fertilizer solution is then filtered continuously by the filter screen 6. During the process, more and more impurities will accumulate on the surface of the filter screen 6. At this time, the two sets of nuts 12 can be screwed on to gradually move away from the threaded rod 11 at the end, so that they no longer limit the position of the bracket 9. Then, the two sets of brackets 9 can be slid along the table shaft 8 to make the two sets of brackets 9 move away from each other. With the flexibility of the bellows 13, the filter tube 4 can be easily pulled out from the end of the outer tube 2. After rinsing the filter screen 6 inside the filter tube 4, it can be reinstalled. When installing the filter tube 4, the annular piece 5 at its end needs to be embedded into the annular groove 3 of the outer tube 2 (to ensure safety). (After ensuring accurate positioning), tighten the nut 12 again, allowing it to move axially along the end threaded rod 11 and firmly abut against the clamp 9 until the two clamps 9, together with the rubber pad 10, tightly and stably hold and limit the filter tube 4. Then, the filter tube 4 can be easily installed. To reduce conveying resistance and leakage risk, the electric push rod 16 can be activated to push and pull the concave plate 17. During this process, the drive plate 19 will rotate along the plate shaft 18 while deflecting, and the other end of the drive plate 19 will swing through the guide shaft 20. The plate 21 is driven to make the plate 21 move in a circle around the rotating shaft 22 at a certain angle. During this time, the rotating shaft 22 will rotate synchronously. The rotation of the rotating shaft 22 will drive the sleeve 23 to rise in angle. The connecting head 14 passing through the sleeve 23 will then "raise" or "lower" (raise or lower in angle), thereby indirectly adjusting the external angle. This allows the corrugated pipe 13 to connect the water source and the water fertilizer machine 1 more smoothly, avoiding pipe bending or twisting caused by improper angle, thereby reducing the water flow resistance and improving the conveying efficiency.

[0029] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
