Description

Technical Field

[0001] This invention belongs to the technical field of integrated water and fertilizer machines, and relates to an integrated water and fertilizer machine that is easy to maintain. Background Technology

[0002] my country is a major producer of agricultural products and also a major consumer of water and fertilizer. However, the effective utilization rate of water and fertilizer is not entirely satisfactory. Traditional natural irrigation achieves a water utilization rate of only about 40%. Large amounts of unused water carry away applied fertilizer, resulting in serious waste of resources and energy, and also causing pollution to the agricultural ecological environment.

[0003] The integrated water and fertilizer machine uses a pressure system to mix soluble solid or liquid fertilizers with irrigation water according to soil nutrient content and crop nutrient requirements. The mixture is then supplied through a controllable pipeline system, ensuring the water and fertilizer are well combined. The solution is then sprayed evenly, at set times, and in measured quantities onto the crop's growth area via pipes, spray guns, or nozzles. This keeps the soil in the main growth area loose and at a suitable moisture content. Furthermore, the machine is designed to meet the different nutrient requirements of various crops, soil conditions, nutrient content, and growth stages, providing water and nutrients directly to the crops at set times and in measured quantities, in precise proportions.

[0004] In the operation of integrated water and fertilizer machines, water is generally drawn from rivers. River water contains silt and other debris. To prevent the debris from clogging the drip irrigation network, filtration is usually used to remove the debris. Existing filtration devices mostly use replaceable filter cartridges, which need to be replaced regularly. This frequent replacement results in high filter cartridge costs. Moreover, the pumping device must be stopped during replacement, and the filter cartridge must be disassembled and replaced, which is inconvenient for the maintenance of the water storage tank and the integrated water and fertilizer machine. Furthermore, the integrated water and fertilizer machine must be turned off when the filter cartridge is replaced, which affects fertilization efficiency. Therefore, we propose an integrated water and fertilizer machine that is easy to maintain. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an easy-to-maintain integrated water and fertilizer machine. The technical problem this device aims to solve is: how to extend the replacement cycle of the filter element in the integrated water and fertilizer machine, reduce the number of maintenance operations, and improve fertilization efficiency.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] An easy-to-maintain integrated water and fertilizer machine includes a base plate and a filter assembly. The filter assembly includes a filter cylinder with several legs fixed below it and above the base plate. The bottom of the filter cylinder is inverted conical. A lifting cylinder is fixed above the filter cylinder, with a feed inlet at its bottom. A rotating shaft is rotatably mounted inside the lifting cylinder, and an auger is mounted on the rotating shaft. A second cover plate is mounted above the filter cylinder, and an auger motor is fixed above the second cover plate. The output shaft of the auger motor is connected to the rotating shaft via a coupling. An inverted plate is fixed on the lifting cylinder, and a water inlet pipe is fixed to the side of the inverted plate. The filter cylinder is filled with quartz sand. A cleaning assembly is mounted above the lifting cylinder, and a return filter assembly and a stirring assembly are mounted above the base plate.

[0008] The working principle of this invention is as follows: The inlet pipe transports river water into the interior of the inverted plate, which buffers the river water. The river water flows upward through the quartz sand, which filters the water, leaving impurities in the sand. After the filtered water accumulates to a certain height, it flows into the return filter assembly, which performs secondary filtration. The cleaning assembly pumps the secondary filtered water into the interior of the lifting cylinder. The output shaft of the auger motor is connected to the rotating shaft via a coupling. The rotating shaft lifts the bottom quartz sand to the top of the lifting cylinder, where the cleaning assembly cleans the quartz sand inside. The cleaned quartz sand then falls back into the filter cylinder, allowing for repeated filtration. The secondary filtered water is then transported to the mixing assembly, which mixes the river water and fertilizer. After mixing, the water and fertilizer are transported to the planting area for irrigation.

[0009] The filter return assembly includes a filter box with two support plates fixed at the bottom. The two support plates are fixed above the base plate. A filter element is installed inside the filter box. A drain pipe is connected to the bottom of the filter element. A second control valve is installed on the drain pipe. A water outlet pipe is installed above the filter box. The end of the water outlet pipe is connected to the filter cylinder. A third cover plate is installed above the filter box. A third control valve is installed inside the filter element.

[0010] With the above structure, the filtered river water flows into the interior of the filter element through the outlet pipe. The filter element performs secondary filtration on the river water. After filtration, the river water flows into the interior of the stirring assembly. The connection between the filter box and the stirring assembly is closed, the third control valve is closed, and the second control valve is opened. The filtered river water flows into the interior of the filter element through the outlet pipe. The river water is blocked by the third control valve and flows out through the upper end of the filter element. Then it flows into the interior of the filter element through the lower end to rinse the dirt inside the filter element. The rinsing wastewater is discharged through the drain pipe.

[0011] The cleaning assembly includes a water pump and two conical cylinders. The water pump is fixed inside the filter box, and the outlet end of the water pump is connected to a water suction pipe. The end of the water suction pipe is connected to the lifting cylinder. Both conical cylinders are fixed inside the filter box and are connected to the lifting cylinder through pipes. A sand discharge pipe is fixed below the conical cylinders, and a fourth control valve is installed on the sand discharge pipe. A connecting pipe is fixed above the two conical cylinders, and a U-shaped pipe is fixed to the end of the two connecting pipes. A sewage discharge pipe is connected below the U-shaped pipe.

[0012] Using the above structure, the water pump draws the secondary filtered river water into the inside of the lifting cylinder. The river water flows the quartz sand inside the lifting cylinder into the conical cylinder. The conical cylinder causes the quartz sand and water flow inside to rotate and mix, thereby washing the quartz sand. Finally, the quartz sand will fall to the bottom of the conical cylinder. The washing wastewater flows into the U-shaped pipe through the connecting pipe, and then is discharged through the sewage pipe. When the fourth control valve is opened, the washed quartz sand falls into the filter cylinder through the sand drop pipe.

[0013] The mixing assembly includes a mixing cylinder, which is fixed above the base plate. A stirring shaft is rotatably installed inside the mixing cylinder, and several stirring blades are installed on the stirring shaft. A first cover plate is installed above the mixing cylinder, and a stirring motor is fixed above the first cover plate. The output shaft of the stirring motor is connected to the stirring shaft through a coupling. Two feed boxes are installed above the first cover plate.

[0014] Using the above structure, fertilizer is placed into the feed box, which then transports the fertilizer into the mixing drum. The stirring motor drives the stirring shaft to rotate via the output shaft, which in turn drives several stirring blades to rotate, mixing the river water and fertilizer.

[0015] The mixing assembly also includes a water and fertilizer pipe and a connecting pipe. The two ends of the connecting pipe are connected to a filter box and a mixing cylinder, respectively. A first control valve is installed on the connecting pipe. The water and fertilizer pipe is fixed on the mixing cylinder. A pressure pump is fixed on the water and fertilizer pipe. The end of the water and fertilizer pipe is connected to a drip irrigation network.

[0016] With the above structure, the mixed water and fertilizer flow into the water and fertilizer pipe, and the pressure pump pressurizes the water and fertilizer inside the water and fertilizer pipe and delivers it to the drip irrigation network, which then drip irrigates the crops.

[0017] Compared with existing technologies, this easy-to-maintain integrated water and fertilizer machine has the following advantages:

[0018] Through the coordinated use of filtration, recirculation, and cleaning components, a water pump draws secondary-filtered river water into the lifting cylinder. The river water carries the quartz sand inside the lifting cylinder into the conical cylinder. The conical cylinder causes the quartz sand and water to rotate and mix, thus cleaning the quartz sand. Finally, the quartz sand falls to the bottom of the conical cylinder, and the cleaning wastewater is discharged through a connecting pipe. Opening the fourth control valve allows the cleaned quartz sand to fall into the filter cylinder through the sand drop pipe, enabling the quartz sand to repeatedly filter the river water. Closing the first and third control valves and opening the second control valve allows the filtered river water to flow into the filter element through the outlet pipe. The river water is blocked by the third control valve and flows out through the top of the filter element, then flows back into the filter element through the bottom, rinsing the dirt inside the filter element. The rinsing wastewater is discharged through the drain pipe, allowing the filter element and quartz sand to be reused, extending the replacement cycle, facilitating maintenance, reducing costs, and improving fertilization efficiency.
