Description

Technical Field

[0001] This solution belongs to the field of agricultural machinery technology, specifically involving an integrated irrigation device that combines fertilizer applicator and filter. Background Technology

[0002] Irrigation refers to watering the land with water or fertilizer, mainly including flood irrigation, sprinkler irrigation, micro-sprinkler irrigation, drip irrigation, seepage irrigation, and deficit irrigation, and is divided into pre-sowing irrigation, seedling irrigation, growing season irrigation, and winter irrigation. Traditionally, sprinkler irrigation is used to irrigate crops. In areas where crops are grown in large quantities, to ensure sufficient water supply, they are usually located in places with rivers or lakes. However, drawing water from rivers or lakes presents a problem: river water or lake water contains a lot of silt and impurities. Without effective filtration, silt and impurities can easily clog the water pipes and sprinklers.

[0003] Therefore, an existing publication (announcement) number CN105210534A discloses an irrigation and fertilization system, comprising: a sedimentation tank; a forebay located within the sedimentation tank; irrigation water treated by the sedimentation tank placed in the forebay; a water pump, a filter element, and a micro-irrigation network sequentially connected to the forebay; a fertilizer tank connected between the water pump and the filter element; and an outlet pipe of the fertilizer tank connected to the forebay. The water pump and the filter element are connected via a main pipeline; the fertilizer tank is connected to the main pipeline via an inlet pipe, and the diameter of the main pipeline is larger than the diameter of the inlet pipe. A three-way valve for controlling the liquid flow rate is also provided between the main pipeline and the inlet pipe.

[0004] The aforementioned irrigation and fertilization system uses sedimentation tanks to remove impurities and silt from the water. However, this system requires water to be introduced into the sedimentation tanks beforehand to remove impurities and silt. Since the sedimentation process takes a long time, water cannot be drawn from rivers immediately for irrigation. This results in the inability to draw water in time when irrigation is urgently needed, causing the best irrigation opportunity for crops to be missed. Utility Model Content

[0005] The purpose of this solution is to provide an integrated irrigation device that combines fertilizer applicator and filtration to address the problem that existing irrigation and fertilization systems cannot quickly extract and filter water.

[0006] To achieve the above objectives, this solution provides an integrated irrigation device combining a fertilizer applicator and a filter, including a frame and a water storage tank mounted on the frame, and a filter assembly disposed within the water storage tank, the filter assembly comprising:

[0007] A filter chamber is fixedly installed at the bottom of the water storage tank;

[0008] A water inlet is provided on the side wall of the filter chamber and communicates with the filter chamber.

[0009] A drain pipe is provided in the filter chamber, and one end of the drain pipe is rotatably connected to the filter chamber.

[0010] A drain hole is provided on the side wall of the drain pipe and is connected to the drain pipe;

[0011] A stirring blade is disposed on the outer wall of the drain pipe;

[0012] A pumping unit, which is used to pump water from the drain pipe.

[0013] The principle and effect of this solution are as follows: When the pumping unit is activated, river water in the storage tank flows into the filtration chamber through the inlet. The water flow impacts the agitator blades, causing the drain pipe to rotate. During the rotation, impurities and dust are drawn to the inner wall of the filtration chamber by centrifugal force. Water near the drain pipe, being at the center of rotation, has a relatively lower impurity content. This cleaner water enters the drain pipe through the drain hole and is ultimately pumped out by the pumping unit for irrigation. With this equipment, this solution eliminates the need for pre-sedimentation of river water, allowing for direct intake and immediate filtration of water from rivers, shortening preparation time and enabling rapid operation when irrigation is urgently needed.

[0014] Furthermore, the central axis of the drain pipe coincides with the central axis of the filter chamber.

[0015] The principle and effect of this solution are as follows: By aligning the central axis of the drain pipe with the central axis of the filter chamber, when the pumping unit draws water from the drain pipe, the river water flows into the filter chamber through the inlet and is evenly distributed along the circumference of the filter chamber. As the water flow drives the agitator blades to rotate the drain pipe, a more stable vortex is formed. This allows impurities and dust in the river water to be more evenly dispersed towards the inner wall of the filter chamber under centrifugal force, enhancing the aggregation effect of impurities and further improving the filtration efficiency. Simultaneously, because the drain pipe is located in the center of the filter chamber, the water flow near the drain pipe is in the central region of the vortex, resulting in a relatively lower impurity content, thus ensuring that the water entering the drain pipe from the drain hole and being pumped out is cleaner.

[0016] Furthermore, the pumping unit includes a pumping pipe and a pumping pump. The inlet end of the pumping pipe is connected to the outlet pipe via a rotary joint, the outlet end of the pumping pipe is connected to the inlet end of the pumping pump, and the outlet end of the pumping pump is connected to an irrigation component.

[0017] The principle and effect of this scheme are as follows: the water pump is used to draw water from the drain pipe, so that the water entering the filter chamber has a large impact, which is enough to drive the stirring blades to rotate, thereby filtering impurities. Finally, the water is transported to the farmland by the irrigation components after passing through the water pump and the water pipe.

[0018] Furthermore, the number of stirring blades is multiple sets, and the multiple sets of stirring blades are spaced apart along the length direction of the drain pipe; the number of water inlet holes and drain holes is multiple, and they are spaced apart along the length direction of the filter chamber and the drain pipe, respectively.

[0019] The principle and effect of this scheme are as follows: through the above settings, after the water flows into the filter chamber from multiple inlet holes, it can more fully impact multiple sets of stirring blades, drive the drain pipe to rotate, and form a stronger swirling effect.

[0020] Furthermore, both the water inlet and the drain are equipped with a sealing ball and a spring. The sealing ball is used to seal the water inlet and the drain. One end of the spring is fixedly connected to the sealing ball, and the other end is fixedly connected to the water inlet or the drain.

[0021] The principle and effect of this solution are as follows: when water needs to enter the filter chamber through the inlet or the drain pipe through the drain hole, the water pressure will overcome the spring force and push the sealing ball to move, so that the inlet or drain hole opens and the water flows smoothly; when the water flow stops or the pressure decreases, the spring force will push the sealing ball back to its original position and reseal the hole, thereby preventing impurities from flowing back or water from leaking.

[0022] Furthermore, both the water inlet and the drain outlet have a frustum-shaped cross-section.

[0023] The principle and effect of this design are as follows: the frustum-shaped perforation structure allows water to flow through in a gradually changing channel. When water enters the inlet, the constricted section of the frustum-shaped perforation accelerates the flow velocity and enhances the impact force of the water on the agitator blades. Simultaneously, the frustum-shaped perforation structure, combined with the sealing ball and spring, results in a better sealing effect.

[0024] Furthermore, a filter screen is provided inside the water inlet, and the filter screen is located outside the sealing ball; the sealing ball is a magnetic sealing ball, and the end of the stirring blade near the sealing ball is provided with a magnetic surface with the same magnetism as the sealing ball.

[0025] The principle and effect of this solution are as follows: The filter screen is used to intercept larger impurities and grass roots in the river water, preventing them from entering the filtration chamber. When the stirring blades rotate, they drive the magnetic surface to rotate synchronously. Since the magnetic surface and the sealing ball have the same magnetism, a repulsive force is generated when the magnetic surfaces approach each other, intermittently pushing the sealing ball away from the filter screen. Subsequently, the sealing ball rebounds under the action of a spring, periodically impacting the filter screen and generating vibration. This vibration shakes off the impurities adhering to the filter screen, preventing clogging and ensuring the unobstructed flow of water into the inlet.

[0026] Furthermore, both the water inlet and the drain are provided with grooves for guiding the sealing ball, and the sealing ball is slidably connected to the grooves.

[0027] The principle and effect of this solution are as follows: the groove is used to provide positioning and guidance for the movement of the sealing ball, so as to prevent it from dislodging.

[0028] Furthermore, it also includes a feeding assembly, which includes a fertilizer storage tank, a press pump, and a feeding pipe. One end of the feeding pipe is fixedly connected to a drain pipe, and the feeding pipe communicates with the drain pipe. The outer wall of the feeding pipe is provided with a turntable, and the turntable is provided with a protrusion. The water inlet of the press pump is connected to the fertilizer storage tank, and the water outlet of the press pump is connected to the feeding pipe through a rotary joint. The pressing head of the press pump is configured to cooperate with the protrusion.

[0029] The principle and effect of this solution are as follows: when the drain pipe rotates, the turntable rotates accordingly, and the protrusion intermittently pushes the pressing head of the pump, causing the pump to draw fertilizer solution (liquid fertilizer) from the fertilizer storage tank and transport it through the supply pipe to the drain pipe, where it mixes with the filtered river water, thus achieving simultaneous irrigation and fertilization. This solution achieves automatic fertilizer addition through a simple mechanical structure, requiring no additional power.

[0030] Furthermore, the irrigation assembly includes a blower and a sprinkler head. The blower is mounted on a frame and connected to a drive source. The sprinkler head has the back side of the blower blades and is connected to the outlet of a water pump.

[0031] The principle and effect of this solution are as follows: the drive source drives the fan to rotate, the fan blades rotate to generate airflow, and at the same time the water pump delivers filtered water mixed with fertilizer to the nozzle. When the water flows through the nozzle, it is atomized by the airflow generated by the fan and sprayed evenly on the surface of the crops, thereby expanding the irrigation coverage and improving the irrigation and fertilization effect.

Detailed Implementation

[0040] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model.

[0041] Example:

[0042] Please see Figures 1-3 The fertilizer applicator and filter integrated irrigation device provided in this embodiment includes a frame 1 and a water storage tank 2 and an irrigation component 5 fixedly installed on the frame 1. The irrigation component 5 includes a blower 51 and a nozzle 52. The blower 51 is mounted on the frame 1 and is connected to a drive source. The drive source comes from a micro-tiller (not shown) connected to the frame 1. A drive shaft 56 is rotatably connected to the frame 1 and is connected to the output end of the diesel engine of the micro-tiller, thereby driving the drive shaft 56 to rotate. A drive wheel 54 and a first pulley 53 are coaxially fixedly connected to the drive shaft 56. The drive wheel 54 is connected to a second pulley 55 via a belt drive. The first pulley 53 is connected to a third pulley 57 via a belt drive. The third pulley 57 is coaxially fixedly connected to the rotating shaft of the blower 51. The nozzle 52 is provided with the back of the fan blades of the blower 51. The nozzle 52 is connected to the outlet end of the water pump 37. The input end of the water pump 37 is coaxially and fixedly connected to the second pulley 55 to provide a power source for the water pump 37.

[0043] Please see Figures 4-7The system also includes a filter assembly 3 located within the water storage tank 2. The filter assembly 3 comprises a filter chamber 31 and a drain pipe 32. The filter chamber 31 is fixed to the center of the bottom of the water storage tank 2 by welding. Its side wall has three frustum-shaped water inlets 311 evenly spaced along the length of the filter chamber 31 and connected to the filter chamber 31. The drain pipe 32 is located within the filter chamber 31 and is rotatably connected to the bottom of the filter chamber 31 via a rotary joint. The central axis of the drain pipe 32 coincides with the central axis of the filter chamber 31, placing the water flow near the drain pipe 32 in the central region of the swirling flow, resulting in a relatively lower impurity content. This ensures that the water entering the drain pipe 32 from the drain holes 321 and being drawn out is cleaner. The side wall of the drain pipe 32 has three sets of drain holes 321 spaced along the length of the drain pipe 32 and the cross-section of the drain holes 321 is frustum-shaped and connected to the drain pipe 32. The outer wall of the drain pipe 32 is welded with three sets of stirring blades 33 arranged axially, and the three sets of stirring blades 33 are spaced apart along the length of the drain pipe 32. Magnetic sheets are embedded on the surface of the stirring blades 33 near the water inlet 311. The system also includes a pumping unit, which consists of a pumping pipe 36 and a pumping pump 37. The inlet end of the pumping pipe 36 is connected to the drain pipe 32 via a rotary joint, and the outlet end is connected to the inlet of the pumping pump 37.

[0044] Both the inlet hole 311 and the drain hole 321 are equipped with a sealing ball 34 and a spring 35. The sealing ball 34 is used to seal the inlet hole 311 and the drain hole 321. Both the inlet hole 311 and the drain hole 321 are equipped with a sliding groove (not shown) for guiding the sealing ball 34. The sealing ball 34 is slidably connected to the sliding groove. One end of the spring 35 is fixedly connected to the sealing ball 34, and the other end is fixedly connected to either the inlet hole 311 or the drain hole 321. A filter screen 38 is provided in the inlet hole 311, and the filter screen 38 is located outside the sealing ball 34. The sealing ball 34 is a magnetic sealing ball 34, and the stirring blade 33 has a magnetic surface with the same magnetism as the sealing ball 34 at one end near the sealing ball.

[0045] During operation, the water pump 37 starts, and the river water in the storage tank 2, after being initially filtered by the filter screen 38, flows at high speed into the filter chamber 31 through the inlet hole 311. The water flow impacts the stirring blades 33, causing the drain pipe 32 to rotate and forming a centrifugal flow field. Impurities are deposited on the inner wall of the filter chamber 31 under the action of centrifugal force. The purified water enters the drain pipe 32 through the drain hole 321 and is finally delivered to the nozzle 52 by the water pump 37. The airflow generated by the rotating fan 51 atomizes and diffuses the water sprayed from the nozzle 52, achieving uniform irrigation over a large area. At the same time, during the rotation of the stirring blades 33, their magnetic metal plates periodically generate magnetic repulsion with the sealing ball 34, causing the sealing ball 34 to compress the spring 35 and disengage from the orifice. Subsequently, under the action of the spring's restoring force, it strikes the filter screen 38 at high frequency, generating vibration to clear blockages.

[0046] Please see Figure 5The system also includes a feeding assembly 4, which comprises a fertilizer storage tank (not shown), a pump 41, and a feeding pipe 42. The fertilizer storage tank stores liquid fertilizer. One end of the feeding pipe 42 is welded to the top of the drain pipe 32 and communicates with its interior; the other end is connected to the outlet of the pump 41 via a rotary joint. The outer wall of the feeding pipe 42 is equipped with a turntable 43, on which protrusions 44 are provided. The inlet of the pump 41 is connected to the fertilizer storage tank, and the outlet of the pump 41 is connected to the feeding pipe 42 via a rotary joint. The pump head of the pump 41 is configured to cooperate with the protrusions 44 for intermittently pressing the pump head. When the drain pipe 32 rotates, it drives the feeding pipe 42 to rotate, causing the turntable 43 to rotate with the feeding pipe 42. The protrusions 44 periodically press the pump 41, quantitatively injecting fertilizer from the fertilizer storage tank into the drain pipe 32, achieving simultaneous liquid and fertilizer application.
