This invention discloses an unloading valve for agricultural machinery and the agricultural machinery itself. The unloading valve includes a valve body and an unloading assembly. The valve body has an installation cavity and an unloading oil passage, with the inlet and outlet of the unloading oil passage connected to the installation cavity. The unloading assembly includes a valve stem and a sliding drive component. The valve stem is slidably disposed within the installation cavity, and the sliding drive component is disposed on the valve body and drivenly connected to the valve stem. The sliding drive component drives the valve stem to slide to open or close the inlet. A clearance gap is provided between the valve stem and the cavity wall of the installation cavity. This clearance gap allows impurities to enter and pass through, enabling them to be flushed along the installation cavity into the unloading oil passage and discharged during the process of oil scouring the clearance gap. This effectively prevents valve stem slippage and jamming caused by impurity accumulation, providing strong anti-pollution and impurity removal capabilities. It is suitable for agricultural operations involving a wide variety and large quantity of impurities, with continuous impurity intrusion.

The application discloses a kind of coating based on metal organic framework and its preparation method and application, the raw material of the coating includes hydrophilic modified metal organic framework and polymer matrix;The channel of the hydrophilic modified metal organic framework is decorated with at least one hydrophilic functional group in sulfonic acid group, carboxyl, amino and quaternary ammonium group;The polymer matrix includes at least one of polyvinylidene fluoride-hexafluoropropylene copolymer, fluorinated polyurethane, acrylic resin.The coating is preferentially adsorbed by internal functional metal organic framework nanoparticles Environment water vapor, prevent surface condensation from physically occur, to realize efficient, durable, stable anti-fog effect, and have high light transmittance and excellent mechanical durability.
