Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of irrigation equipment, and particularly relates to a water and fertilizer integrated irrigation system. BACKGROUND

[0002] Water and fertilizer integration technology refers to a new agricultural technology integrating irrigation and fertilization. The water and fertilizer integrated drip irrigation equipment, with the aid of a pressure system (or natural terrain difference), dissolves solid or liquid fertilizer into fertilizer solution according to the soil nutrient content and crop fertilizer requirement rule, and uniformly drips the fertilizer solution into the soil near the crop roots through the pipe laid in the field along with irrigation water. The water and fertilizer integration technology can meet the water and nutrient requirements of crops in the key growth period through artificial quantitative control, greatly improves the water and fertilizer utilization efficiency, and saves manpower and material resources.

[0003] The water and fertilizer integrated device supplied in the market has the following shortcomings, which leads to very limited use in actual production, high device price, requirement of flat farmland and open terrain, unsuitability for mountainous areas with large terrain undulation and irregular terrain, requirement of fixed power supply, and inconvenience of power supply in large field planting. The irrigation device is blocked due to insufficient dissolution of fertilizer, unreasonable design of the filtering device or deposition of fertilizer in the conveying pipeline. SUMMARY

[0004] Based on the problems mentioned in the above background technology, the application provides a water and fertilizer integrated irrigation system for solving the problems of great terrain limitation of the existing irrigation and easy blockage of the pipeline.

[0005] The technical scheme adopted by the application is as follows:

[0006] A water and fertilizer integrated irrigation system comprises a mounting vehicle, a traction frame connected to the mounting vehicle, a water pump, a controller and a storage battery installed on the mounting vehicle, a water inlet pipe connected to the water inlet end of the water pump, a first filter connected to the water outlet end of the water pump, a second filter connected to the water outlet end of the first filter, a drainage main pipe connected to the water outlet end of the second filter, an irrigation pipe connected to the drainage main pipe, a water tank frame provided on the mounting vehicle, a mixing tank and a water and fertilizer tank installed in the water tank frame from top to bottom, a stirrer installed in the mixing tank, a drain pipe with a valve connected between the mixing tank and the water and fertilizer tank, a three-way valve connected to the drainage main pipe, a water inlet auxiliary pipe connected to the drainage main pipe through the three-way valve, a drainage auxiliary pipe connected between the water and fertilizer tank and the water inlet pipe, and an electromagnetic valve installed on the drainage auxiliary pipe.

[0007] On the basis of the above technical scheme, the application also has the following improvements:

[0008] Further, the first filter is a centrifugal filter. The sand, suspended matter and other solid particles in the water can be separated, avoiding the solid particles in the water from entering the mixing box and affecting the water and fertilizer mixing.

[0009] Further, the second filter is a hand-operated filter, and the hand-operated filter is connected with a first blowdown pipe. The second filter can be cleaned at any time, which is beneficial to maintaining the filtering capacity of the second filter.

[0010] Further, a third filter is installed on the water drainage auxiliary pipe. The third filter can filter the fertilizer that is not completely dissolved in the water discharged from the water and fertilizer tank.

[0011] Further, a carport is installed on the mounting vehicle, and a solar panel connected with the storage battery is installed on the top of the carport. The storage battery can be charged by the solar panel, which is beneficial to better outdoor use of the irrigation system.

Under the action of the water pump, the water flows into the tank body from the water inlet interface, penetrates through the filter layer for filtering, and then flows out of the drainage interface. The water flowing through the cleaning groove body sweeps the cleaning groove body and penetrates through the filter layer, so that too much water does not directly flow into the cleaning groove body. The water penetrating through the filter layer can be introduced into the backwashing groove body under the action of the water diversion groove body, so as to locally flush the filter layer. Since the opening of the backwashing groove body corresponds to the opening of the cleaning groove body, and the water flow in the cleaning groove body is small, the sewage produced by the backwashing of the filter layer in the backwashing groove body can be discharged through the residue discharge pipe. The water flow can flush the paddle wheel, so as to drive the rotating shaft and the residue discharge pipe to rotate, thereby driving the backwashing groove body and the cleaning groove body to rotate, and the filter screen can be more comprehensively cleaned.

[0013] Further, the filter layer comprises an inner ring body and an outer ring body, a filter screen is installed between the inner ring body and the outer ring body, a reinforcing rod is arranged in the filter screen, and the reinforcing rod is arranged in the inner ring body and the outer ring body at two ends respectively. The two ends of the filter screen are in contact with the opening ends of the backwashing groove body and the cleaning groove body. The high strength of the filter layer makes the filter screen not easy to deform, so that the backwashing groove body and the cleaning groove body can better contact the filter screen, which is beneficial to improving the cleaning effect.

[0014] Further, the cleaning groove is provided with a mounting groove, a cleaning brush roller in contact with the filter screen is mounted in the mounting groove, the cleaning brush roller is coaxially connected with a gear, and the inner ring body is provided with a gear ring, and the gear is engaged with the gear ring. Under the cooperation of the gear ring and the gear, when the cleaning groove rotates around the center of the filter screen, the cleaning brush roller can be driven to rotate to sweep the sundries attached to the filter screen into the cleaning groove, so that the weeds, fibers, large particles and other large impurities can be cleaned, the filtering effect is good, and the irrigation system is suitable for outdoor water sources such as rivers, lakes and ponds.

[0015] Further, the tank body includes a first half tank and a second half tank, the water outlet is arranged on the first half tank, the water inlet is arranged on the second half tank, sealing snap rings are arranged on the first half tank and the second half tank, the outer ring body is located between the two sealing snap rings, and the threaded connection between the rotating shaft and the residue discharge pipe is opposite to the rotating direction of the paddle wheel. The tank body is convenient to disassemble, and the internal components of the tank body are convenient to maintain and replace.

[0016] The beneficial effects of the present application are as follows:

[0017] The irrigation system is convenient to move, compact in structure, beneficial to the volume of the irrigation system, convenient to use in different outdoor areas, and less limited by terrain. The irrigation system can be used for irrigation by pumping water alone, can be used for water and fertilizer integrated irrigation by introducing a water and fertilizer system in the irrigation process, and can better meet the use requirements.
