Description

Technical Field

[0001] This utility model belongs to the field of irrigation and fertilization technology, and specifically relates to a miniaturized integrated irrigation, filtration and fertilization machine. Background Technology

[0002] After the fertilizer is dissolved, it is injected into the irrigation system and drip irrigation is formed through pipes and drippers. It is applied directly, evenly and quantitatively to the root layer of crops, so that the soil of the main root system is always loose and has a suitable moisture content, truly achieving simultaneous water and fertilizer application. However, the existing irrigation water is not effectively filtered after being pumped out, which can easily lead to blockage of the irrigation pipes.

[0003] A search revealed a Venturi integrated water and fertilizer irrigation and fertilization device (CN219803053U), comprising a centrifugal pump, a Venturi water jet injector, a water-fertilizer mixture output pipe, an inlet pipe, and a fertilizer suction pipe. The inlet of the Venturi water jet injector is connected to the inlet pipe and two fertilizer suction pipes. The inlet pipe is equipped with a vent valve and a pressure gauge. The outlet of the Venturi water jet injector is connected to the inlet of the centrifugal pump, and the outlet of the centrifugal pump is connected to the water-fertilizer mixture output pipe. The fertilizer suction pipe includes a fertilizer suction port, a visual float flow meter, a needle valve, a solenoid valve, and a check valve connected in sequence. The check valve is connected to the Venturi water jet injector. However, this device has the following drawbacks: no filter is installed at the water-fertilizer mixture output pipe or the fertilizer suction port, making it impossible to filter impurities in the water-fertilizer mixture. This leads to nozzle blockage during irrigation and fertilization, affecting irrigation and fertilization efficiency.

[0004] A search revealed an integrated irrigation and fertilization fertilizer applicator with the existing technology announcement number CN222283961U. This applicator includes a fixed base with casters at all four corners of its lower end. A push handle is fixedly installed on the left end of the fixed base. An irrigation tank is located in the middle of the upper end of the fixed base, and an irrigation mechanism is located at the lower right end of the irrigation tank. A storage box is fixedly installed on the left end of the irrigation tank, and a motor is fixedly installed in the middle of the right end of the irrigation tank. A rotating rod is fixedly installed at the output end of the motor. Four stirring rods are located on the upper and outer surfaces of the rotating rod, and a bearing is located on the left side of the outer surface of the rotating rod. A feed hopper is located at the upper end of the irrigation tank. However, this applicator has the following drawbacks: the irrigation water is not filtered, which can easily lead to impurities entering the irrigation pipe during irrigation, thus clogging the nozzles. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a miniaturized integrated irrigation, filtration, and fertilization machine. The inlet tee, outlet tee, filtration mechanism, and fertilization mechanism are mounted on a base, allowing for manual transport to the irrigation and fertilization area. This embodies the characteristics of a miniaturized integrated machine. Furthermore, the filter in the filtration mechanism filters the irrigation water. When the filter needs cleaning, the filter inlet control valve and the main outlet control valve are closed, while the backwash control valve and the filter outlet control valve are opened. The irrigation water flowing to the outlet tee reverses its flow, passing through the filter outlet pipe and entering the filter to clean it. The water is then discharged through the backwash control valve and backwash pipe. The fertilization mechanism is connected to the inlet tee, allowing liquid fertilizer to mix with the irrigation water, further integrating irrigation and fertilization. A float flow meter determines the fertilizer input, and the flow regulating valve controls the fertilizer application rate.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A miniaturized integrated irrigation, filtration, and fertilization machine includes a base, an inlet tee pipe, an outlet tee pipe, a filtration mechanism, and a fertilization mechanism. Both the filtration and fertilization mechanisms are fixed to the base. The inlet and outlet tee pipes are connected to opposite ends of the filtration mechanism. One end of the inlet tee pipe is equipped with an inlet control valve, and the other end of the outlet tee pipe is equipped with an outlet control valve. One end of the fertilization mechanism is connected to the inlet tee pipe. Irrigation water enters the filtration mechanism through the inlet tee pipe, is filtered, and then discharged from the outlet tee pipe to irrigate crops. Simultaneously, liquid fertilizer enters the inlet tee pipe through the fertilization mechanism and mixes with the irrigation water, thus achieving integrated irrigation and fertilization.

[0008] The filtration mechanism has two sets, which are respectively connected to the outlet end of the inlet tee pipe and the inlet end of the outlet tee pipe. The filtration mechanism includes a filter inlet pipe, a filter, a filter outlet pipe, and a backwash pipe. One end of the filter inlet pipe is connected to the outlet end of the inlet tee pipe, and the filter outlet pipe is connected to the inlet end of the outlet tee pipe. A filter inlet control valve is provided on the filter inlet pipe. A filter outlet control valve is provided on the filter outlet pipe. The filter is connected between the filter inlet control valve and the filter outlet control valve. A backwash pipe is provided between the filter inlet control valve and the filter. A backwash control valve is provided on the backwash pipe. Irrigation water enters the filter inlet pipes of the two sets of filtration mechanisms through the inlet tee pipes, and then enters the filter through the filter inlet pipes for filtration. The filtered irrigation water flows through the filter outlet pipe to the outlet tee pipe for discharge and irrigation.

[0009] When the filter needs cleaning, close the filter inlet control valve and the main outlet control valve in one set of filter mechanisms, and open the backwash control valve and the filter outlet control valve in the same set of filter mechanisms. The irrigation water that flows to the outlet tee pipe through another set of filter mechanisms flows backward through the filter outlet pipe with the filter outlet control valve opened and enters the filter to clean the filter. Then it is discharged through the opened backwash control valve and backwash pipe.

[0010] The fertilization mechanism includes a fertilizer inlet pipe, a float flow meter, connecting pipe I, a Y-type filter, connecting pipe II, a fertilizer pump, a fertilizer discharge pipe, and a pipeline. One end of the fertilizer inlet pipe is connected to the float flow meter, and connecting pipe I is connected to the other end of the float flow meter. A flow regulating valve is installed on connecting pipe I. A Y-type filter is installed between connecting pipe I and connecting pipe II. The fertilizer pump is fixed on the base, and both ends of the fertilizer pump are connected to connecting pipe II and the fertilizer discharge pipe, respectively. The end of the fertilizer discharge pipe away from the fertilizer pump is connected to the pipeline between the inlet tee and the main inlet control valve. A [further details about the fertilizer discharge pipe are needed for accurate translation]. The check valve, a one-way valve, prevents irrigation water in the inlet tee from flowing into the fertilizer discharge pipe. Liquid fertilizer enters the Y-type filter through the fertilizer inlet pipe, float flow meter, and connecting pipe I. The Y-type filter filters out impurities, and the filtered liquid fertilizer then enters the inlet tee through connecting pipe II, fertilizer pump, and fertilizer discharge pipe, thus mixing the liquid fertilizer with the irrigation water and achieving integrated irrigation and fertilization. The amount of fertilizer inlet is first determined by the float flow meter, and then the amount of fertilizer is controlled by adjusting the flow regulating valve.

[0011] The filter includes a housing, an end cap, and a columnar filter screen. The housing has an inlet and an outlet; the inlet is connected to a filter inlet pipe, and the outlet is connected to a filter outlet pipe. The end cap is threaded onto the housing. One end of the columnar filter screen rests against the end cap, and the other end is connected to the outlet inside the housing. When the filter needs cleaning, the filter inlet control valve and filter outlet control valve in one set of filter mechanisms are closed, allowing irrigation water to pass through another set for filtration and irrigation. Then, the end cap of the filter with the filter inlet control valve closed is removed, and the columnar filter screen is disassembled and cleaned. This allows for simultaneous cleaning of the filter and irrigation, improving irrigation efficiency.

[0012] A pressure gauge is installed between the main water outlet control valve and the water outlet tee; the pressure gauge can monitor the water flow rate, thereby controlling the irrigation.

[0013] The fertilizer inlet pipe is equipped with an exhaust valve; the exhaust valve can prevent excessive pressure inside the fertilizer inlet pipe, thus preventing liquid fertilizer from entering the fertilizer inlet pipe.

[0014] The fertilizer inlet pipe is connected to a fertilizer inlet hose by a thread at one end. The fertilizer inlet hose is provided with a fertilizer inlet head at the end away from the fertilizer inlet pipe, and a filter screen is provided on the fertilizer inlet head.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1) Irrigation water enters the filter inlet pipes of the two filter units through the inlet tee pipes, and then enters the filter for filtration. The filtered irrigation water flows through the filter outlet pipe to the outlet tee pipe for discharge and irrigation. When the filter needs to be cleaned, the filter inlet control valve and the main outlet control valve in one filter unit are closed, and the backwash control valve and the filter outlet control valve in the same filter unit are opened. The irrigation water flowing to the outlet tee pipe of the other filter unit flows backward through the filter outlet pipe with the filter outlet control valve opened and enters the filter to clean the filter. Then it is discharged through the opened backwash control valve and backwash pipe.

[0017] 2) Liquid fertilizer enters the Y-type filter through the fertilizer inlet pipe, float flow meter, and connecting pipe I. The Y-type filter filters out impurities. The filtered liquid fertilizer then enters the inlet tee pipe through connecting pipe II, fertilizer pump, and fertilizer discharge pipe, thus mixing the liquid fertilizer with the irrigation water and achieving integrated irrigation and fertilization. The amount of fertilizer is first determined by the float flow meter, and then the amount of fertilizer is controlled by adjusting the flow regulating valve. Attached Figure Description

Detailed Implementation

[0024] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-5 The technical solution of this utility model will be further described in detail below.

[0025] A miniaturized integrated irrigation, filtration, and fertilization machine includes a base 1, an inlet tee pipe 2, an outlet tee pipe 3, a filtration mechanism 4, and a fertilization mechanism 5. The filtration mechanism 4 and the fertilization mechanism 5 are both fixed to the base 1. The inlet tee pipe 2 and the outlet tee pipe 3 are respectively connected to both ends of the filtration mechanism 4. One end of the inlet tee pipe 2 is equipped with an inlet control valve 201, and one end of the outlet tee pipe 3 is equipped with an outlet control valve 301. One end of the fertilization mechanism 5 is connected to the inlet tee pipe 2. Irrigation water enters the filtration mechanism 4 through the inlet tee pipe, is filtered by the filtration mechanism 4, and is then discharged from the outlet tee pipe 3 to irrigate crops. Simultaneously, liquid fertilizer enters the inlet tee pipe 2 through the fertilization mechanism 5 and mixes with the irrigation water, thereby achieving an integrated irrigation and fertilization effect.

[0026] The filtration mechanism 4 has two sets, which are respectively connected to the outlet end of the inlet tee pipe 2 and the inlet end of the outlet tee pipe 3; the filtration mechanism 4 includes a filter inlet pipe 401, a filter 402, a filter outlet pipe 403, and a backwash pipe 404; one end of the filter inlet pipe 401 is connected to the outlet end of the inlet tee pipe 2, and the filter outlet pipe 403 is connected to the inlet end of the outlet tee pipe 3; a filter inlet control valve 4011 is provided on the filter inlet pipe 401; a filter outlet control valve 4031 is provided on the filter outlet pipe 403, and the filter... 402 is connected between the filter inlet control valve 4011 and the filter outlet control valve 4031. A backwash pipe 404 is provided between the filter inlet control valve 4011 and the filter 402. A backwash control valve 4041 is provided on the backwash pipe 404. Irrigation water enters the filter inlet pipes 401 of the two sets of filter mechanisms 4 through the inlet tee pipe 2, and then enters the filter 402 through the filter inlet pipe 401 for filtration. The filtered irrigation water flows through the filter outlet pipe 403 to the outlet tee pipe 3 for discharge and irrigation.

[0027] When filter 402 needs to be cleaned, close the filter inlet control valve 4011 and the main outlet control valve 301 in one set of filter mechanisms 4, and open the backwash control valve 4041 and the filter outlet control valve 4031 in the same set of filter mechanisms 4. The irrigation water flowing to the outlet tee pipe 3 through another set of filter mechanisms 4 flows backward through the filter outlet pipe 403 with the filter outlet control valve open and enters the filter 402 to clean the filter 402. Then it is discharged through the open backwash control valve 4041 and the backwash pipe 404.

[0028] The fertilization mechanism 5 includes a fertilizer inlet pipe 501, a float flowmeter 502, a connecting pipe I 503, a Y-type filter 504, a connecting pipe II 505, a fertilizer pump 506, a fertilizer discharge pipe 507, and a pipeline. One end of the fertilizer inlet pipe 501 is connected to the float flowmeter 502, and the connecting pipe I 503 is connected to the other end of the float flowmeter 502. A flow regulating valve 5031 is provided on the connecting pipe I 503. A connection is provided between the connecting pipe I 503 and the connecting pipe II 505. There is a Y-type filter 504; the fertilizer pump 506 is fixed on the base 1. The two ends of the fertilizer pump 506 are connected to the connecting pipe II 505 and the fertilizer discharge pipe 507 respectively. The end of the fertilizer discharge pipe 507 away from the fertilizer pump 506 is connected to the pipeline between the water inlet tee pipe 2 and the water inlet control valve 201; the fertilizer discharge pipe 507 is equipped with a check valve 5071. The check valve 5071 is a one-way valve that can prevent irrigation water in the water inlet tee pipe 2 from flowing into the fertilizer discharge pipe 507.

[0029] Liquid fertilizer enters the Y-type filter 504 through the fertilizer inlet pipe 501, float flow meter 502, and connecting pipe I 503. The Y-type filter 504 filters out impurities. The filtered liquid fertilizer then enters the water inlet tee pipe 2 through the connecting pipe II 505, fertilizer pump 506, and fertilizer discharge pipe 507, thus mixing the liquid fertilizer with the irrigation water and achieving integrated irrigation and fertilization. The amount of fertilizer inlet is first determined by the float flow meter 502, and then the amount of fertilizer is controlled by adjusting the flow regulating valve 5031.

[0030] The filter 402 includes a housing 4021, an end cap 4022, and a columnar filter screen 4023. The housing 4021 has an inlet and an outlet. The inlet is connected to the filter inlet pipe 401, and the outlet is connected to the filter outlet pipe 403. The end cap 4022 is threaded onto the housing 4021. One end of the columnar filter screen 4023 abuts against the end cap 4022, and the other end is connected to the outlet inside the housing 4021. When the filter 402 needs cleaning, the filter inlet control valve 4011 and the filter outlet control valve 4031 in one set of filter mechanisms 4 are closed, allowing irrigation water to be filtered and irrigated through another set. Then, the end cap of the filter 402 with the filter inlet control valve 4011 closed is removed, and the columnar filter screen 4023 is disassembled and cleaned. This allows the cleaning of the filter 402 and irrigation to be carried out simultaneously, improving irrigation efficiency.

[0031] A pressure gauge 302 is installed between the main water outlet control valve 301 and the water outlet tee pipe 3; the pressure gauge 302 can monitor the water flow rate, thereby controlling the irrigation.

[0032] The fertilizer inlet pipe 501 is equipped with an exhaust valve 5011; the exhaust valve 5011 can prevent the pressure inside the fertilizer inlet pipe 501 from being too high, so that liquid fertilizer cannot enter the fertilizer inlet pipe 501.

[0033] The fertilizer inlet pipe 501 is connected to a fertilizer inlet hose 5012 by a thread. The end of the fertilizer inlet hose 5012 away from the fertilizer inlet pipe 501 is provided with a fertilizer inlet head 5013, and a filter screen is provided on the fertilizer inlet head 5013. The fertilizer inlet hose 5012 and the fertilizer inlet head 5013 are placed into the fertilizer cylinder to draw in fertilizer.

[0034] A miniaturized irrigation, filtration, and fertilization integrated machine operates as follows: Irrigation water enters the filter inlet pipes 401 of two sets of filter mechanisms 4 through the inlet tee pipe 2, and then enters the filter 402 for filtration through the filter inlet pipe 401. The filtered irrigation water flows through the filter outlet pipe 403 to the outlet tee pipe 3 for discharge and irrigation. At the same time, liquid fertilizer enters the Y-type filter 504 through the fertilizer inlet pipe 501, float flow meter 502, and connecting pipe I 503. The Y-type filter 504 filters impurities, and then the filtered liquid fertilizer enters the inlet tee pipe 2 through the connecting pipe II 505, fertilizer pump 506, and fertilizer discharge pipe 507, thereby mixing the liquid fertilizer with the irrigation water and further achieving integrated irrigation and fertilization.

[0035] First, the amount of fertilizer is determined by the float flowmeter 502, and then the amount of fertilizer is controlled by adjusting the flow regulating valve 5031. When the filter 402 needs to be cleaned, the filter inlet control valve 4011 and the main outlet control valve 301 are closed, and the backwash control valve 4041 and the filter outlet control valve 4031 are opened. The irrigation water flowing to the outlet tee pipe 3 flows backward through the filter outlet pipe 403 and into the filter 402 to clean the filter 402. Then, it is discharged through the backwash control valve 4041 and the backwash pipe 404.

[0036] In summary, the following valves, including but not limited to the main inlet control valve, main outlet control valve, filter inlet control valve, filter outlet control valve, backwash control valve, air vent valve, flow regulating valve, and check valve, are standard valves in the prior art, obtained through private customization or purchase; the float flow meter is a flow meter in the prior art, obtained through private customization or purchase; and the Y-type filter is a filter in the prior art, obtained through private customization or purchase.
