Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] Please refer to Figures 1-5 The utility model provides the following technical scheme: a kind of control terminal for agricultural intelligent irrigation, including metal box 1 and the controller 3 of metal box 1 inside assembly, the surface of metal box 1 front end sealing door is equipped with display screen 5, the surface of metal box 1 front end sealing door is equipped with control button 4, the lateral wall of metal box 1 is connected with heat dissipation side plate 2, the outside wall of metal box 1 is installed with hollow protective box 6, filter screen 7 is inserted in the inside of protective box 6, the outside wall of one end of filter screen 7 is connected with first magnetic block 8, the surface of the corner mounting lug of protective box 6 is connected with first bolt 9 through screw thread, through hole 10 is set on the surface of protective box 6, the outside wall of protective box 6 is connected with knob 14, and second magnetic block 15 is installed at the end of knob 14.

[0023] Preferably, the size of the protective box 6 is greater than the size of the heat dissipation side plate 2, and the protective box 6 is made of metal.

[0024] Preferably, the protective box 6 is detachably connected with the metal box 1 through the first bolt 9.

[0025] Preferably, the filter screen 7 is detachably connected with the protective box 6 through the first magnetic block 8 and the second magnetic block 15, the filter screen 7 is in the shape of "T", and the end of the filter screen 7 connected with the first magnetic block 8 is made of metal material, and the connection part of the filter screen 7 with the protective box 6 is provided with a sealing gasket.

[0026] Preferably, the metal box 1 is provided with a fixing block 11 at the back end of the four corners, and the fixing block 11 is welded with the metal box 1.

[0027] Preferably, the surface of the end of the fixing block 11 away from the metal box 1 is connected with a rubber pad 12, and the four corners of the rubber pad 12 are threadedly connected with second bolts 13.

[0028] Preferably, the rubber pad 12 is detachably connected with the fixing block 11 through the second bolts 13.

[0029] Working principle: First, the control terminal is composed of the controller 3, the control button 4 and the display screen 5. The model of the controller 3 is Siemens S7-200 controller, the mounting ears integrally connected on the metal box 1 are stably mounted on the mounting plate near the intelligent irrigation system through screws, and the setting of the fixing block 11 and the rubber pad 12 ensures that the metal box 1 maintains a certain gap with the mounting plate. Such design enables the natural wind to smoothly blow the back of the metal box 1, effectively taking away the heat and further improving the heat dissipation efficiency, ensuring the stable operation of the equipment. As the core, the controller 3 is connected with the water pump and the water valve in the agricultural intelligent irrigation system, and through the operation of the control button 4, the water pump can be easily started and the water valve can be opened to guide the water flow to accurately irrigate the farmland.

[0030] It should be particularly pointed out that the rubber pad 12 is elastically deformed when being connected with the mounting plate through the screws, effectively preventing the metal box 1 from shaking when being blown by the natural wind. In addition, the rubber pad 12 is made of wear-resistant and corrosion-resistant material.

[0031] When using the control terminal, the dust in the air first enters the inside of the protective box 6 through the through hole 10, and then is effectively intercepted by the filter screen 7. The filtered clean air then flows to the heat dissipation side plate 2 through the through hole 10. In this process, the filter screen 7 plays a key filtering role, preventing dust from entering through the heat dissipation side plate 2 and threatening the circuit of the controller 3, thereby significantly enhancing the dustproof performance of the control terminal.

[0032] The protective box 6 is conveniently and detachably fixed with the metal box 1 through the first bolt 9, and a sealing gasket is additionally arranged at the back end of the protective box 6 to ensure good sealing between the protective box 6 and the metal box 1. This makes dust only enter the protective box 6 through the through hole 10, and then flow through the heat dissipation side plate 2. During this period, the filter screen 7 filters the dust in the air inside the protective box 6, ensuring that the gas entering the metal box 1 is harmless to the controller 3.

[0033] In addition, the filter screen 7 is connected with the protection box 6, and is also provided with a sealing gasket to keep the sealing state. The first bolt 9 is designed to facilitate the easy removal of the protection box 6 from the outer wall of the metal box 1, and the second magnetic block 15 is separated from the rotation of the first magnetic block 8 through the rotation knob 14, facilitating the quick disassembly and replacement when the filter screen 7 is blocked, ensuring the continuous and efficient operation of the control terminal. At the same time, the filter screen 7 needs to be replaced regularly to avoid the influence of blockage on the filtering and heat dissipation effect. The filter screen 7 and the heat dissipation side plate 2 are intentionally left with a gap to ensure smooth air flow.

[0034] Finally, after the filter screen 7 is inserted into the protection box 6, the second magnetic block 15 is magnetically connected with the first magnetic block 8 by rotating the knob 14, so as to fix the filter screen 7. When disassembling, the second magnetic block 15 is rotated to be separated from the first magnetic block 8, so as to avoid the second magnetic block 15 blocking the filter screen 7.

[0035] Finally, it should be pointed out that: the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
