The application discloses a front light guide plate for a reflective display device and a manufacturing method thereof, comprising a light guide plate body with an incident light surface and an exit light surface oppositely arranged; a plurality of light guide dots formed on the exit light surface for guiding light from the incident light surface to a display surface of the reflective display device; wherein the light guide dots are conical or pyramidal; when the light guide dots are conical, the ratio of the bottom width A to the depth B is less than 0.1; when the light guide dots are pyramidal, the included angle between the inclined surface and the bottom surface is between 55 degrees and 70 degrees. The application optimizes the shape parameters of the dots, so that the light is more efficiently guided to the display surface, thereby significantly improving the overall display brightness under the same light source conditions.

This utility model discloses a coal mine transportation and pushing device, specifically relating to the field of coal mine transportation technology. It includes a conveyor platform, with a support and adjustment device fixedly connected to the lower end of the conveyor platform. A base plate is fixedly connected to the lower end of the support and adjustment device. A fixed frame is fixedly connected to the upper right side of the conveyor platform, and a dust collection and filtering device is fixedly connected to the upper end of the fixed frame. The coal mine transportation and pushing device of this utility model can be flexibly adjusted by tilt angle, enabling the coal mine transportation equipment to combine high efficiency, safety, and economy. Coal mine roadways have varying slopes; the adjustable tilt angle allows the equipment to quickly match the roadway undulations, avoiding material accumulation or slippage due to incompatible slopes. The same equipment can adapt to different transportation needs through angle adjustment, reducing equipment model dependence. An appropriate tilt angle can accelerate the descent of materials using their own weight, reducing conveyor belt drive power and saving energy consumption. The tilt angle also helps materials flow smoothly, improving transportation continuity.
