Description

Technical Field

[0001] This utility model relates to the technical field of fertilization and irrigation auxiliary devices, specifically an automated water and fertilizer machine based on the Internet of Things. Background Technology

[0002] A fully automatic fertigation machine is an agricultural machinery device that integrates irrigation and fertilization. Through an automated control system, it precisely delivers the required water and fertilizer to the roots or leaves of crops according to a set ratio and time, achieving the goal of scientific irrigation and fertilization. Existing fertigation machines use well water, river water, or tap water as their water source. The water is filtered through a centrifugal filter and a disc filter before being injected into the main pipeline. Liquid fertilizer is injected into the main pipeline via a fertilizer pump, and then the water and fertilizer are transported to the areas requiring irrigation. This type of machine has a relatively complex structure and high manufacturing costs.

[0003] The relevant reference CN212910781U discloses an IoT-based integrated water and fertilizer machine, which includes a support frame, a control cabinet, water and fertilizer transmission pipes, and a vertical centrifugal pump. The control cabinet is fixed on the support frame and also includes a movable bracket, which is hinged to the back of the control cabinet. The water and fertilizer transmission pipes and the vertical centrifugal pump are movably fixed on the movable bracket. The movable bracket is equipped with a suction block, and the support frame is equipped with a position-adjustable limiting block. The suction block can be attached to the back of the control cabinet or the limiting block. The rotation of the movable bracket drives the water and fertilizer transmission pipes and the vertical centrifugal pump to rotate. However, the fertilizer tank is relatively easy to clog, and the irrigation efficiency is relatively low. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automated water and fertilizer machine based on the Internet of Things that prevents the fertilizer tank from getting clogged and improves irrigation efficiency.

[0005] To address the above technical issues, this utility model provides an automated water and fertilizer machine based on the Internet of Things, including a controller, a transfer pump, and a spray pump. The transfer pump is installed on the inlet of one side wall of the water and fertilizer tank, and the outlet is provided on the other side wall of the water and fertilizer tank. The transfer pump is connected to a water source. An end cap is provided on the top surface of the water and fertilizer tank, and a fertilizer pipe is provided on the end cap. A stainless steel filter plate is provided inside the water and fertilizer tank. One side of the stainless steel filter plate is installed on the bottom surface of the end cap, and the other side of the stainless steel filter plate is clipped to the bottom edge of the water and fertilizer tank. A stirring device is also provided on the end cap.

[0006] By adopting the above technical solution, a filter plate is installed inside the water and fertilizer tank, and a stirring device is installed on the water and fertilizer tank. Impurity filtration and water and fertilizer stirring are integrated into one water and fertilizer tank, which simplifies the structure, reduces manufacturing costs, and prevents the water and fertilizer tank from clogging, resulting in higher irrigation efficiency.

[0007] Preferably, the stainless steel filter plate is mounted on the bottom surface of the end cap via a hinge on one side.

[0008] By adopting the above technical solution, when installing the stainless steel filter plate into the water and fertilizer tank, you only need to first align the hinged side of the stainless steel filter plate with the corresponding position on the bottom surface of the end cap and fix the hinge, then clip the other side of the stainless steel filter plate into the inner bottom edge of the water and fertilizer tank, and finally put the end cap on the water and fertilizer tank to complete the installation of the stainless steel filter plate. Compared with other complicated connection methods, this greatly simplifies the installation process of the filter device and saves installation time and labor costs.

[0009] Preferably, the fertilizer pipe and the mixing device are located on both sides of the stainless steel filter plate, with the fertilizer pipe near the inlet and the mixing device near the outlet.

[0010] By adopting the above technical solution, the fertilizer pipe is close to the inlet, and the continuous inflow of water will keep the fertilizer solution in a dynamic flow state. The stirring device is close to the outlet, and the kinetic energy of the natural flow of water is used to assist the mixing, reducing the motor load and reducing energy consumption.

[0011] Preferably, the output port is connected to the spray pump via a pipe.

[0012] By adopting the above technical solution, the spray pump generates strong suction and pressure, which draws out the uniform water and fertilizer solution that has been dissolved, stirred and filtered in the water and fertilizer tank from the outlet and delivers it to the irrigation area.

[0013] Preferably, a slot is provided on the inner side wall of the output port.

[0014] By adopting the above technical solution, it is easy to install ceramic filter plates.

[0015] Preferably, a sealing ring is provided in the groove, and the ceramic filter plate is installed in the groove through the sealing ring.

[0016] By adopting the above technical solution, the sealing ring firmly fixes the ceramic filter plate in the groove, preventing the ceramic filter plate from shaking or shifting under the impact of the water and fertilizer solution, thus further improving the filtration effect.

[0017] Preferably, the stirring device includes a stirring motor, a stirring shaft mounted on the stirring motor, and a stirring paddle mounted on the stirring shaft.

[0018] By adopting the above technical solution, the stirring motor can stably transmit power to the stirring paddle through the stirring shaft. This direct power transmission method reduces energy loss and the probability of transmission failure.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model has a filter plate inside the water and fertilizer tank and a stirring device on the water and fertilizer tank, which integrates impurity filtration and water and fertilizer stirring into one water and fertilizer tank, simplifying the structure, reducing manufacturing costs, and preventing the water and fertilizer tank from clogging, thus achieving higher irrigation efficiency.

[0021] 2. When installing the stainless steel filter plate into the water and fertilizer tank, this utility model only requires aligning the hinged side of the stainless steel filter plate with the corresponding position on the bottom surface of the end cap and fixing the hinge. The other side of the stainless steel filter plate is then secured to the inner bottom edge of the water and fertilizer tank. Finally, the end cap is placed on the water and fertilizer tank to complete the installation of the stainless steel filter plate. This greatly simplifies the installation process of the filtration device and saves installation time and labor costs.

[0022] 3. The fertilizer pipe of this utility model is located near the inlet, and the continuous inflow of water will keep the water-fertilizer solution in a dynamic flow state. The stirring device is located near the outlet, and the kinetic energy of the natural flow of water is used to assist mixing, reduce the motor load, and reduce energy consumption.

The transfer pump 2 is installed on the inlet 5 on one side wall of the water and fertilizer tank 4, and the other side wall of the water and fertilizer tank 4 has an outlet 6. The inner side wall of the outlet 6 has a slot 12 for easy installation of a ceramic filter plate 14. The transfer pump 2 is connected to a water source. The top surface of the water and fertilizer tank 4 has an end cap 7, and a fertilizer pipe 8 is installed on the end cap 7. A stainless steel filter plate 9 is installed inside the water and fertilizer tank 4. One side of the stainless steel filter plate 9 is installed on the bottom surface of the end cap 7, and the other side of the stainless steel filter plate 9 is clipped to the bottom edge of the water and fertilizer tank 4. A stirring device 10 is also installed on the end cap 7. This application integrates impurity filtration and water and fertilizer stirring into a single water and fertilizer tank 4 by installing a filter plate 9 inside the water and fertilizer tank 4 and a stirring device on the water and fertilizer tank 4. This simplifies the structure, reduces manufacturing costs, and prevents the water and fertilizer tank 4 from clogging, resulting in higher irrigation efficiency.

[0030] like Figure 3 As shown, one side of the stainless steel filter plate 9 is mounted on the bottom surface of the end cover 7 via a hinge 11. Using the hinge 11, when installing the stainless steel filter plate 9 into the water-fertilizer tank 4, simply align the side of the stainless steel filter plate 9 with the corresponding position on the bottom surface of the end cover 7 and secure the hinge 11. The other side of the stainless steel filter plate 9 is then secured to the inner bottom edge of the water-fertilizer tank 4. Finally, the end cover 7 is placed on the water-fertilizer tank 4, completing the installation of the stainless steel filter plate 9. Compared to other complex connection methods, this greatly simplifies the installation process of the filtration device, saving installation time and labor costs.

[0031] The fertilizer pipe 8 and the stirring device 10 are located on both sides of the stainless steel filter plate 9, with the fertilizer pipe 8 near the inlet 5 and the stirring device 10 near the outlet 6. The fertilizer pipe 8 is near the inlet 5, and the continuous inflow of water keeps the fertilizer solution in a dynamic flow state. The stirring device is near the outlet 6, and the kinetic energy of the natural flow of water is used to assist mixing, reduce the motor load, and lower energy consumption.

[0032] The outlet 6 is connected to the sprinkler pump 3 through a pipe. The sprinkler pump 3 generates strong suction and pressure, which draws out the uniform water and fertilizer solution, which has been dissolved, stirred and filtered in the water and fertilizer tank 4, from the outlet 6 and delivers it to the irrigation area.

[0033] like Figure 4 As shown, a sealing ring 13 is provided in the groove 12, and the ceramic filter plate 14 is installed in the groove 12 through the sealing ring 13.

[0034] like Figure 5As shown, the stirring device 10 includes a stirring motor 15, a stirring shaft 16 mounted on the stirring motor 15, and a stirring paddle 17 mounted on the stirring shaft 16. The stirring motor 15 stably transmits power to the stirring paddle 17 through the stirring shaft 16. This direct power transmission method reduces energy loss and the probability of transmission failure.

[0035] The controller 1 is electrically connected to the transfer pump 2, the spray pump 3, and the stirring motor 15. During operation, the controller 1 turns on the transfer pump 2 and the stirring motor 15. Fertilizer is fed into the water-fertilizer tank 4 through the fertilizer pipe 8, and water is pumped into the water-fertilizer tank 4 through the inlet 5. After the water and fertilizer are initially mixed, they are filtered through the stainless steel filter plate 9 hinged to the bottom of the end cover 7 and stirred by the stirring paddle 17. The spray pump 3 is turned on, and after stirring, the water-fertilizer mixture is filtered again through the ceramic filter plate 14 and then pumped out by the spray pump 3.
