The utility model relates to rice planting technical field discloses a rice planting fertilizer even scattering equipment, including installation base, the rear side fixedly connected with backplate of installation base, the front side of backplate is equipped with the mounting groove, the inside wall of mounting groove is detachably connected with the storage box, the front side bottom end fixedly connected with the fixed base of storage box outer wall, the inside wall left and right sides of fixed base all are connected with the clamping plate of sliding, the front end of clamping plate similar side is connected through the tension spring, the inside wall middle end sliding of fixed base is connected with the push -plate, the clamping plate is connected with installation base through the connecting component. In the utility model, through mounting groove and the detachable storage box and clamping plate, tension spring linkage structure, realized storage box quick replacement, even broadcast, shorten the stop time of continuing material, and utilize the flow limiting plate locating groove and the cooperation of positioning block, form the standardization flow gear position and even scattered scattering, promote efficiency and uniformity.

This application provides a light-emitting diode (LED) and a light-emitting device. A first electrode is formed on one side of the first semiconductor layer of the LED. The first electrode has multiple body portions distributed on opposite sides of the LED and multiple extension portions electrically connected to the body portions. The multiple extension portions include main extension portions and secondary extension portions distributed in a first direction and a second direction. This design increases the number of body portions of the first electrode and adaptively increases the number and distribution of the extension portions, thus shortening the current conduction distance, improving current spreadability, and making the current distribution of the LED more uniform. Simultaneously, the increased number of body portions correspondingly increases the number of leads between the LED and external circuits, thereby reducing the equivalent resistance of the LED and ultimately lowering the voltage of the LED package, reducing input power, and thus improving the photoelectric conversion efficiency of the LED.
