[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] like Figures 1-6 As shown, a mobile pressurized water and fertilizer integrated device includes a tractor 2 and a water and fertilizer integrated machine 1. The water and fertilizer integrated machine 1 is mounted on the tractor 2 and is driven by the tractor 2 to move.

[0019] The integrated water and fertilizer machine 1 includes a fertilizer tank 11, a centrifugal filter 12, a mesh filter 13, a fertilizer pump 14, a booster pump 15, and a control mechanism 16. The centrifugal filter 12 adopts the existing centrifugal dust and sand filter. The centrifugal filter 12 is installed on the frame 21 of the tractor 2. The water inlet of the centrifugal filter 12 is equipped with a water inlet valve. The water inlet of the centrifugal filter 12 is connected to the water inlet pipe 17 through the water inlet valve. The water inlet pipe 17 is used to connect to the water source. The water from the water source can flow into the centrifugal filter 12 through the water inlet pipe 17 for centrifugal filtration treatment.

[0020] A purification pipe 18 is also connected to the inlet pipe 17. A purification valve is installed on the purification pipe 18. The inlet valve and the purification valve can be ordinary ball valves, which can be manually adjusted to open or close. Alternatively, solenoid valves can be used. When using solenoid valves, the inlet valve and the purification valve can be connected to the control mechanism 16, which allows for remote control of the opening and closing of each valve. When supplying water to the centrifugal filter 12, the purification valve is first opened and the inlet valve is closed. Water from the source is discharged from the purification valve. After the initial water containing more impurities flows out, the purification valve is closed and the inlet valve is opened, allowing cleaner water to flow into the centrifugal filter 12 and then into the integrated water and fertilizer machine 1 for use.

[0021] In order to meet the pressure requirements of the pipeline system during normal use of the water and fertilizer integrated machine 1, a pressure relief valve is also installed on the water inlet pipe 17, and a pressure gauge is installed at the pressure relief valve.

[0022] The centrifugal filter 12 has a water supply pipe 19 connected to its outlet. A tee fitting is located at the end of the water supply pipe 19, connecting the water supply pipe 19 to the inlet of the tee fitting. One outlet of the tee fitting is equipped with a drip irrigation valve, which is connected to a mesh filter 13 via a pipe. The other outlet of the tee fitting is equipped with a sprinkler valve, which is connected to the inlet of a booster pump 15 via a pipe. Water entering the centrifugal filter 12 flows into the water supply pipe 19 after centrifugal filtration. When the drip irrigation valve is open and the sprinkler valve is closed, the water in the water supply pipe 19 flows to the mesh filter 13, where it is filtered again before being used for drip irrigation. When the sprinkler valve is open and the drip irrigation valve is closed, the water in the water supply pipe 19 flows to the booster pump 15, where it is pressurized for sprinkler irrigation.

[0023] The mesh filter 13 employs existing mesh filtration equipment for water treatment, preferably a mesh filter 13 with a backwashing function. The mesh filter 13 is mounted on the frame 21 of the tractor 2. In a preferred embodiment, there are at least two, and preferably three, mesh filters 13 arranged side-by-side. The inlet of each mesh filter 13 is connected to the same inlet manifold 113, which is connected to the outlet of a three-way fitting via a drip valve. The outlet of each mesh filter 13 is connected to the same outlet manifold, which is equipped with a drip connection suitable for connection to a drip irrigation component. The drain of each mesh filter 13 is connected to the same drain manifold, which has a drain outlet. When the drip irrigation valve is open and the sprinkler irrigation valve is closed, the water in the water supply pipe 19 can be distributed to each mesh filter through the inlet manifold 113 for treatment. The water treated by each mesh filter flows into an outlet manifold and into the external drip irrigation component connected to the drip irrigation connection. The dirt accumulated in each mesh filter 13 can be discharged centrally through the drain outlet.

[0024] The booster pump 15 is a prior art booster pump 15 device. The water outlet of the booster pump 15 is connected to a sprinkler pipe. The sprinkler pipe is provided with a sprinkler connection part, which is an interface suitable for connection with sprinkler equipment. When the sprinkler valve is open and the drip valve is closed, the water in the water supply pipe 19 is sent to the external sprinkler component for sprinkler irrigation through the booster pump 15.

[0025] The fertilizer tank 11 is mounted on the frame 21 of the tractor 2. To secure the fertilizer tank 11 and facilitate disassembly and replacement, a pressure plate with at least two screws is installed on the frame 21 of the tractor 2. The fertilizer tank 11 is positioned behind the tractor 2, with the pressure plate positioned on top of the fertilizer tank 11. The screws are connected to the frame 21 of the tractor 2, thus securing the fertilizer tank 11 to the tractor 2. The fertilizer tank 11 contains a stirring mechanism, a conventional stirring structure including a stirring motor, a stirring rod, and stirring blades distributed on the stirring rod. The stirring motor is mounted on the top of the fertilizer tank 11. The stirring rod extends into the fertilizer tank 11 and is driven to rotate by the stirring motor. The rotation of the stirring rod causes the stirring blades to rotate, thereby thoroughly mixing water and fertilizer within the fertilizer tank 11. The fertilizer tank 11 also has a fertilizer inlet.

[0026] Fertilizer pump 14 is mounted on tractor 2 and is connected to water supply pipe 19 and fertilizer tank 11. Driven by fertilizer pump 14, the stirred water and fertilizer in fertilizer tank 11 are introduced into water supply pipe 19, thus achieving fertilization simultaneously with drip irrigation / sprinkler irrigation. For details, please refer to [link to details]. Figure 4The water supply pipe 19 is connected to a fertilizer inlet pipe 110 and a fertilizer return pipe 111. Following the direction of water flow within the water supply pipe 19, the water supply pipe 19 should first be connected to the fertilizer inlet pipe 110, and then to the fertilizer return pipe 111. The fertilizer inlet pipe 110 is connected to the inlet of the fertilizer pump 14, and the fertilizer return pipe 111 is connected to the outlet of the fertilizer pump 14. The fertilizer tank 11 is equipped with a fertilizer outlet pipe 112, which is connected to the fertilizer inlet pipe 110 via a diaphragm valve. When the fertilizer pump 14 is working, it draws water from the water supply pipe 19 through the fertilizer inlet pipe 110, and simultaneously draws the prepared fertilizer from the fertilizer tank 11 through the fertilizer inlet pipe 110 and the fertilizer outlet pipe 112. Then, the fertilizer and water are pumped into the water supply pipe 19 through the fertilizer return pipe 111. The water supply pipe 19 delivers the fertilizer-containing water to the tee fitting, and irrigation or drip irrigation is carried out as needed. The fertilizer outlet pipe 112 is connected to the fertilizer inlet pipe 110 through a diaphragm valve, which allows fertilizer to flow out of the fertilizer inlet pipe 110 while water flows back to the fertilizer tank 11.

[0027] As a further implementation, to facilitate the mixing of water and fertilizer in the fertilizer tank 11, the fertilizer inlet pipe 110 is also connected to the fertilizer tank 11. A switch valve is installed on both sides of the fertilizer inlet pipe 110 where it connects to the water supply pipe 19. The switch valve can be a common manually adjustable ball valve or a solenoid valve. When adding water to the fertilizer tank 11, the switch valve between the water supply pipe 19 and the fertilizer tank 11 is opened, and the other switch valve is closed. Water in the water supply pipe 19 can flow into the fertilizer tank 11. After sufficient water is added to the fertilizer tank 11, the switch valve between the water supply pipe 19 and the fertilizer tank 11 is closed, and the other switch valve is opened. The integrated water and fertilizer machine 1 can then operate normally.

[0028] A tee structure can also be installed at the connection between the water supply pipe 19 and the fertilizer inlet pipe 110. In this case, the fertilizer inlet pipe 110 is a two-section pipe. One section connects the fertilizer tank 11 to the tee structure, and the other section connects the fertilizer pump 14 to the tee structure.

[0029] As a further embodiment, the fertilizer tank 11 is provided with an upper connecting part at the top position, and the fertilizer inlet pipe 110 is connected to the upper connecting part to connect to the fertilizer tank 11. The fertilizer tank 11 is provided with a lower connecting part at the bottom or lower part of the side wall, and the fertilizer return pipe 111 is connected to the lower connecting part to connect to the fertilizer tank 11.

[0030] The control mechanism 16 includes a control cabinet and a controller installed in the control cabinet. The controller adopts a microcontroller-based control panel of existing technology. The controller is connected to the centrifugal filter 12, the mesh filter 13, the fertilizer pump 14, the booster pump 15, and the stirring mechanism installed in the fertilizer tank 11. The controller can control the working status of the centrifugal filter 12, the mesh filter 13, the fertilizer pump 14, the booster pump 15, and the stirring mechanism. The control panel is also equipped with conventional safety components such as an emergency stop button and working indicator lights.

[0031] Please see Figures 1-6 The tractor 2 includes a frame 21, on which a body 22 is mounted. The water and fertilizer integrated machine 1 is mounted on the frame 21 and located inside the body 22. The body 22 is equipped with a door, through which the water and fertilizer integrated machine 1 can be inspected and maintained. The body 22 is also provided with several mesh holes for the water and fertilizer integrated machine 1 to dissipate heat and exhaust.

[0032] The bottom of the frame 21 is equipped with a front axle mechanism 23 and a rear axle mechanism 24. The rear axle mechanism 24 includes a rear axle frame and a rear wheel. The rear axle frame is connected to the frame 21, and a rear travel wheel is installed on the rear axle frame. The front axle mechanism 23 includes a front axle frame and a front travel wheel. The front axle frame is connected to the frame 21, and a front travel wheel is installed on the front axle frame. Both the front travel wheel and the rear travel wheel are rotatable, which facilitates the movement of the integrated water and fertilizer machine 1. A traction connection part is provided on the front axle frame or the frame 21. Through the traction connection part, it can be connected to vehicles such as tractors, and the machine can be driven by the vehicle.

[0033] The front axle is equipped with bearings, which are connected to the frame 21. The front axle can rotate relative to the frame 21 to achieve reversing.

[0034] As a further embodiment, a braking mechanism 25 is also provided on the front axle frame. The braking mechanism 25 cooperates with the front travel wheel to realize braking.
