Description

Technical Field

[0001] This utility model relates to the field of agricultural drip irrigation technology, and in particular to an open-type drip irrigation fertilization device suitable for drip irrigation systems using surface water as the water source in open fields. Background Technology

[0002] Currently, the technology of applying fertilizer with drip irrigation water in agricultural water-saving drip irrigation has been widely used. The fertilizer application device commonly used in drip irrigation systems is the open-type fertilizer box. When pouring fertilizer into this type of fertilizer box, too much fertilizer should not be poured in at once. It should be poured in multiple times. Moreover, the operation and management personnel should use tools to stir the fertilizer continuously in time to speed up the dissolution of the fertilizer. In particular, some types of fertilizers are prone to clump together when they come into contact with water if they are not stirred in time, which slows down the dissolution rate and affects the normal fertilization. Summary of the Invention

[0003] The purpose of this invention is to provide an open-type drip irrigation fertilization device that utilizes the pressure of the water flow in the main water supply pipe of the drip irrigation head to fully agitate and dissolve the fertilizer poured into the bottom of the fertilizer tank through the high-pressure water flow sprayed from the universal direct-shoot nozzle on the inlet pipe, thereby reducing the workload of manually stirring the fertilizer and ensuring that the dissolved fertilizer is evenly delivered into the drip irrigation system pipeline for drip application.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] An open-type drip irrigation fertilization device includes a water pump, a bottom valve, a suction pipe, a water inlet, a main water supply pipe, an inlet pipe, a fertilizer solution outlet pipe, valves, a fertilizer tank, a filter screen, and a drain valve. It also includes an extension steel pipe and universal direct-fire nozzles. The fertilizer tank is open-type with a drain outlet at the bottom. The fertilizer tank inlet pipe is equipped with regulating valves at both ends. One end is connected to the main water supply pipe at the outlet of the water pump, and the other end is connected to the valve interface near the bottom of the fertilizer tank. The inlet pipe is equipped with an extension steel pipe that extends into the fertilizer tank. Universal direct-fire nozzles are evenly distributed on the extension steel pipe. One end of the fertilizer solution outlet pipe is connected to the suction pipe, and the other end is connected to the fertilizer tank. Regulating valves are installed at both ends of the fertilizer solution outlet pipe.

[0006] In the aforementioned open-type drip irrigation fertilization device, the inlet pipe extends to a distance of 15cm from the inner wall of the other side of the fertilizer box.

[0007] In the aforementioned open-type drip irrigation fertilization device, the extended steel pipe is parallel to the bottom of the fertilizer box and 10cm away from the bottom of the fertilizer box.

[0008] The aforementioned open-type drip irrigation fertilization device has a universal direct-fire nozzle installation spacing of 15cm.

[0009] The aforementioned open-type drip irrigation fertilization device has an internal threaded connector on the extended steel pipe and an external threaded universal direct-fire nozzle. The nozzle and the connector are connected by a thread, and the nozzle is installed parallel to the bottom of the fertilizer box. This nozzle can achieve a maximum vertical spray angle adjustment of 15° through a ball joint, so that the high-pressure water jet from the nozzle can impact the fertilizer at the bottom of the fertilizer box, resulting in more complete fertilizer dissolution.

[0010] The above-mentioned open-type drip irrigation fertilization device has a fertilizer liquid output pipe inside the fertilizer box made of steel pipe, which extends horizontally from the top of the fertilizer box to the center position, and extends vertically downward through a welded elbow. The fertilizer suction port is 20cm away from the bottom of the fertilizer box, and a filter screen is installed at the fertilizer suction port to prevent impurities or undissolved fertilizer particles from entering the pipe.

[0011] Beneficial effects:

[0012] This utility model provides an open-type drip irrigation fertilization device that utilizes the pressure of the water flow in the main water supply pipe of the drip irrigation head to fully agitate and dissolve the fertilizer poured into the bottom of the fertilizer tank through the high-pressure water flow sprayed from the universal direct-shoot nozzle on the water inlet pipe, reducing the workload of manually stirring the fertilizer and allowing the dissolved fertilizer to be evenly delivered into the drip irrigation system pipeline for drip application.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the device of this utility model will be described in detail below with reference to examples and accompanying drawings.

[0020] Example:

[0021] Reference Figure 1-4 This utility model provides a technical solution for an open-type drip irrigation fertilization device applied to a field surface water drip irrigation system using a post-pump filter. The device includes a water pump 10, a bottom valve 2, a suction pipe 3, a water inlet 4, a main water supply pipe 8, an inlet pipe 11, a fertilizer liquid output pipe 6, a valve 7, a fertilizer box 12, an extension steel pipe 14, a filter screen 15, a universal direct-fire nozzle 16, a drain valve 17, and a valve 18.

[0022] The fertilizer tank 12 is open-top, with a drain valve 17 at the bottom. The fertilizer tank inlet pipe 11 is made of transparent plastic steel wire hose, with regulating valves at both ends. One end connects to the main water supply pipe 8 after the water pump, and the other end connects to the valve 13 interface near the bottom of the fertilizer tank 12. The inlet end of the water pump 10 is connected to the suction pipe 3, which extends into the sedimentation tank 1. The outlet end of the water pump is connected to the main water supply pipe 8, which connects to the head filter. The fertilizer tank inlet pipe extends into the fertilizer tank, 15cm from the inner wall on the other side. The extended inlet pipe is made of steel pipe, parallel to the bottom of the fertilizer tank, and 10cm from the bottom. The extended steel pipe 14 is equipped with an internal threaded connector, and a universal direct-spray nozzle 16 is connected to... The connector is provided with an external thread, and the nozzle and the connecting seat are connected by a thread. Universal direct-shot nozzles 16 are evenly distributed on both sides of the extended steel pipe 14, with an installation spacing of 15cm. The nozzle installation direction is parallel to the bottom surface of the fertilizer box. This type of nozzle can achieve a maximum vertical spray angle adjustment of 15° through a ball joint. The fertilizer liquid output pipe 6 is connected to the water suction pipe 3, and adjustment valves are set at both ends. Transparent plastic steel wire hoses are used to facilitate observation of the fertilizer liquid output. The fertilizer liquid output pipe inside the fertilizer box is made of steel pipe, which extends horizontally from the top of the fertilizer box to the center position, and extends vertically downward through a welded elbow. The fertilizer suction port is 20cm away from the bottom of the fertilizer box. A filter screen is set at the fertilizer suction port to prevent impurities or undissolved fertilizer particles from entering the pipe.

[0023] Before starting the drip irrigation system pump, first inject water into the water inlet 4 to expel the air in the suction pipe 3. The bottom valve 2 is used to prevent water backflow. When the air in the suction pipe is expelled, close the outlet valve 7, start the pump, and then gradually open the valve 7 until it is running normally and smoothly.

[0024] The working pressure range of omnidirectional direct-fire sprinklers is typically 0.05–0.35 MPa, while the pressure of the main water supply pipe during drip irrigation is typically 0.20–0.35 MPa, which meets the working pressure requirements of the sprinklers.

[0025] When fertilizing, first fill the fertilizer tank with a certain amount of clean water through the inlet pipe, then pour in a portion of the fertilizer to be dripped. Next, open the inlet valve wider and continue pouring in the fertilizer. Utilizing the pressure of the main water supply pipe at the drip irrigation head, the high-pressure water jet from the universal direct-jet nozzle on the extended steel pipe of the inlet pipe thoroughly agitates and dissolves the fertilizer at the bottom of the fertilizer tank. The spray angle of the universal direct-jet nozzle can be adjusted to ensure complete fertilizer dissolution and reduce the workload of manual fertilizer stirring. When the liquid level is close to the top of the fertilizer tank, close the inlet valve and open the valve on the fertilizer outlet pipe. The dissolved fertilizer will then flow evenly into the water supply pipe and into the drip irrigation system for drip application. To ensure sufficient fertilizer enters the system, when the fertilizer level drops to near the suction port, add clean water and continue fertilizing until the fertilizer solution becomes clear. After fertilization, open the drain valve to remove impurities and excess water from the bottom of the fertilizer tank, preparing for the next fertilization.
