DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-4 The utility model is described in further detail.

[0025] The utility model embodiment discloses a multifunctional municipal green belt irrigation device, referring to Figure 1-2 , including an irrigation mechanism, which includes a water source connecting pipe 1, a diverter 11, several irrigation branches 12 and several sprinklers 13. This irrigation device is suitable for automatic irrigation of urban green belts, especially when there is no rainfall for a long time or the greening area is large and regular and uniform irrigation is required.

[0026] Reference Figure 1The water source connecting pipe 1 is responsible for connecting to the municipal water source. A control valve 16 for controlling the flow of water is fixedly installed in the water source connecting pipe 1. The control valve 16 can control the flow or closure of the water source connecting pipe 1.

[0027] Reference Figure 1-2 The diverter 11 is fixed at one end of the water source connecting pipe 1, and the irrigation branch pipe 12 is fixed at one side of the diverter 11. The diverter 11 is connected downstream of the water source connecting pipe 1 to evenly distribute the water flow to each irrigation branch pipe 12.

[0028] Reference Figure 1-2 A number of nozzles 13 are fixedly installed on the outside of the irrigation branch pipe 12. A number of nozzles 13 are evenly distributed on the irrigation branch pipe 12 to achieve multi-directional uniform irrigation. The nozzles 13 can be rotary nozzles and atomizing nozzles to meet different irrigation needs.

[0029] Reference Figure 1-2 At the bottom of the nozzle 13, there are several soil moisture sensors 15 buried in the ground for real-time monitoring of soil moisture. A regulating valve 14 for adjusting the flow of irrigation water is fixedly installed in the irrigation branch pipe 12. The soil moisture sensor 15 monitors the humidity in the soil in real time, which makes it convenient for users to use the regulating valve 14 to control the irrigation amount of different vegetation according to the soil moisture, avoiding waste of resources or damage to vegetation due to excessive irrigation. The regulating valve 14 can be a flow regulating valve or an electronic regulating valve. The electronic regulating valve can realize remote automatic control of flow, which is a public technology.

[0030] First, open the water source connecting pipe 1 through the control valve 16 to allow water to flow into the diverter 11. Then, according to the vegetation type and water demand of each greening area, adjust the regulating valve 14 on each irrigation branch pipe 12 to control the flow of irrigation water. Finally, start the sprinkler 13 for irrigation.

[0031] Reference Figure 1 and Figure 3 A fertilizer mixer 2 for adding fertilizer to the irrigation water is fixedly provided between the water source connecting pipe 1 and the diverter 11. A filter screen 21 for blocking water-soluble fertilizers that are not fully dissolved is fixedly installed in the fertilizer mixer 2. The filter screen 21 can block water-soluble fertilizers that are not fully dissolved, thereby preventing undissolved water-soluble fertilizers from entering the irrigation branch pipe 12 and other pipelines and causing blockage.

[0032] Reference Figure 1 and Figure 3A feed pipe is fixedly provided at the top inner side of the fertilizer mixer 2, and a valve for controlling the on-off of the bottom end of the fertilizer mixer 2 is provided in the fertilizer mixer 2. The user can add water-soluble fertilizer and water into the fertilizer mixer 2 through the feed pipe. The valve can control the unblocking or closing of the bottom end of the fertilizer mixer 2, so that the bottom end of the fertilizer mixer 2 can be in a closed state during stirring, which is convenient for the fertilizer water to be fully stirred and mixed. The user can also connect the water pipe from the feed pipe and use the water pressure in the water pipe to press the mixed fertilizer water from the fertilizer mixer 2 into the irrigation branch pipe 12, so that the irrigation device can supplement fertilizer to the vegetation in the municipal green belt.

[0033] Reference Figure 1 and Figure 3 The fertilizer mixer 2 is provided with a stirring mechanism, which includes a motor 22 fixed at the top center of the fertilizer mixer 2, a rotating rod 23 fixed at the output end of the motor 22 and coaxial with the fertilizer mixer 2, and a stirring blade 24 fixed on the outer wall of the rotating rod 23 for stirring and mixing the water and fertilizer in the fertilizer mixer 2. After the motor 22 is running, the stirring blade 24 will be driven to rotate through the rotating rod 23, thereby stirring and mixing the water-soluble fertilizer and water in the fertilizer mixer 2 to form fertilizer water.

[0034] Reference Figure 1 、 Figure 3 and Figure 4 A crushing mechanism is provided at the bottom of the stirring mechanism for crushing the agglomerated fertilizer blocked by the filter screen 21. The crushing mechanism includes a push rod 25 fixed to the outer wall of the bottom end of the rotating rod 23 and cooperating with the top of the filter screen 21, and a fixed rod 26 fixed in the fertilizer mixer 2 and staggered with the push rod 25. The fixed rod 26 is located above the push rod 25. A plurality of cone blocks 27 are fixed on one side of the push rod 25 for crushing the agglomerated fertilizer blocked by the fixed rod 26 when the push rod 25 rotates.

[0035] After the rotating rod 23 rotates, it will drive the push rod 25 to rotate. The rotated push rod 25 can push the fertilizer that has agglomerated and settled on the top of the filter 21 toward the fixed rod 26. At this time, the fixed rod 26 will block the fertilizer. As the push rod 25 continues to rotate and cooperates with the top pressure of several cone blocks 27, the agglomerated fertilizer can be broken up to accelerate the dissolution of the fertilizer.

[0036] Reference Figure 1A booster pump 3 for pressurizing when the water source pressure is insufficient is fixedly installed in the water source connecting pipe 1. A solar panel 31 is provided on the outside of the booster pump 3. A battery box 32 is provided at the bottom of the solar panel 31. A battery for powering the booster pump 3 is fixedly installed in the battery box 32. The solar panel 31 can convert solar energy into electrical energy and store it in the battery. The battery can power the booster pump 3. Therefore, when the water source pressure is insufficient, the booster pump 3 can be used to increase the pressure, thereby ensuring the normal operation of the irrigation device and enhancing the independence of the irrigation device and the ability to respond to emergencies.

[0037] The implementation principle of a multifunctional municipal green belt irrigation device according to an embodiment of the utility model is as follows:

[0038] When in use, first open the water source connection pipe 1 through the control valve 16 to allow water to flow into the diverter 11. Then, the water demand of the vegetation in each greening area is determined according to the vegetation type and the soil moisture detected by the soil moisture sensor 15. Then, adjust the regulating valve 14 on each irrigation branch pipe 12 to control the flow of irrigation water. Finally, start the sprinkler 13 for irrigation.

[0039] When it is necessary to add fertilizer to the irrigation water, the user can add the water-soluble fertilizer and water into the fertilizer mixer 2, and control the valve at the bottom of the fertilizer mixer 2 to close the bottom of the fertilizer mixer 2, and then turn on the motor 22. After the motor 22 is running, it will drive the rotating rod 23, the stirring blade 24 and the push rod 25 to rotate. After the stirring blade 24 rotates, it can stir and mix the water-soluble fertilizer and water to form fertilizer water;

[0040] The rotating push rod 25 can push the fertilizer that has agglomerated and settled to the top of the filter screen 21 toward the fixed rod 26. At this time, the fixed rod 26 will block the fertilizer. As the push rod 25 continues to rotate and cooperates with the top pressure of several cone blocks 27, the agglomerated fertilizer can be broken up to accelerate the dissolution of the fertilizer. The fertilizer water can be mixed into the irrigation water by the fertilizer mixer 2, thereby realizing the irrigation and fertilization of the vegetation in the municipal green belt.
