This utility model relates to the field of pet freeze-dried material screening technology, and more particularly to a pet freeze-dried material screening device. Its technical solution includes: a housing; a feeding mechanism is provided on the top surface of one side of the housing; a screening mechanism is provided on the right side of the housing; a support component is provided at the bottom of the housing; a material control component is provided on the top surface of the feeding disc; an adjustment component is provided on one side of each screen plate; and a vibration motor is provided on the bottom surface of the housing's base plate. This utility model, through the combined use of the feeding mechanism and the material control component, achieves uniform material feeding and even material dispersion, avoiding material congestion, ensuring smooth conveying, reducing material impact on the equipment, extending service life, providing a uniform feeding basis for subsequent screening, and improving screening efficiency. By setting up the adjustment component and the guide component, the equipment can adapt to pet freeze-dried materials of different densities or forms, improving the equipment's versatility, optimizing the material residence time on the screen plate, improving screening accuracy, and working in conjunction with the guide component to ensure the stability of the screen plate adjustment.

The present disclosure relates to a Luneberg lens antenna with a position-electrically adjustable feed, which includes: a reflecting plate, a feed, a Luneberg lens, and a position adjusting mechanism. The position adjusting mechanism includes a mounting plate, a motor, a guide rail, a sliding block, a connecting base, a screw and a moving base. A position of the mounting plate is relatively fixed to a position of the Luneberg lens. The guide rail is mounted on the mounting plate. Both ends of the screw are rotationally mounted on the mounting plate. The motor is fixed on the mounting plate and configured for driving the screw to rotate. The moving base is provided with a screw hole, and the screw hole of the moving base is in threaded connection with the screw. The reflecting plate is arranged between the Luneberg lens and the guide rail. The sliding block is mounted on the reflecting plate and in sliding fit connection with the guide rail. One end of the connecting base is connected with the moving base, and the other end of the connecting base is connected with the reflecting plate. The feed is mounted on a surface, facing the Luneberg lens, of the reflecting plate. The present disclosure has characteristics of good stability in adjusting a feed position, convenient assembly and low production cost. The present disclosure further relates to a Luneberg lens antenna group.
