The utility model discloses a material receiving mechanism for automatic production of materials. The material receiving mechanism comprises a material receiving roller way, a buffer baffle assembly and a driving assembly. The receiving roller way is provided with a receiving end and a discharging end and is used for conveying materials; the buffering baffle assembly is arranged near the discharging end of the material receiving roller way in a lifting mode and used for blocking materials and reducing the speed of the materials. The driving assembly is connected with the buffering baffle assembly and used for driving the buffering baffle assembly to move up and down to be higher or lower than the upper surface of the receiving roller way. The buffer baffle assembly comprises a lifting frame, a buffer plate and an elastic piece. The lifting frame is arranged near the discharging end of the material receiving roller way and connected with the driving assembly. The buffer plate is connected to the lifting frame and can ascend and descend together with the lifting frame. A gap is formed between the buffer plate and the lifting frame; the elastic piece is arranged between the lifting frame and the buffer plate, and the two ends of the elastic piece abut against the lifting frame and the buffer plate respectively. The material receiving mechanism for automatic production of the materials can slow down the material speed, and damage to the materials and a production line is avoided.

The utility model discloses a mounting structure of an integrated front end frame, and relates to the field of automobile accessories. According to the scheme, the device comprises a front-end frame, and a connecting piece is integrally fixed to the outer surface of the front-end frame; a connecting mechanism is fixed on the surface of the anti-collision beam, and the connecting piece is in sliding connection with the anti-collision beam through the connecting mechanism; the connecting mechanism comprises a fixed part, a movable part, a guide rod and a spring, the fixed part is fixedly connected with the anti-collision beam, the movable part is connected with the fixed part in a sliding mode, the connecting part is fixedly connected with the movable part, the guide rod sequentially penetrates through the fixed part and the movable part and is connected with the fixed part and the movable part in a sliding mode, the guide rod is sleeved with the spring, and the spring is fixedly connected with the connecting part. The two ends of the spring abut against the fixed part and the movable part respectively. The connecting piece and the front end frame are integrally formed through injection molding, the overall weight of the automobile is reduced, sheet metal parts do not need to be connected, and installation is more convenient.

The application discloses a safety protection device and method for highway construction, which comprises a protection frame, a first protection plate fixedly arranged on the right side of the protection frame, an air bag fixedly arranged on the right side of the first protection plate, a silica gel buffer pad fixedly arranged in the air bag, a plurality of mounting plates arranged in the air bag, a plurality of connecting screws for connecting the mounting plates with the first protection plate, a collapse box fixedly arranged on the right side of the mounting plate, a guide column fixedly arranged on the right side in the collapse box, and the right end of the guide column connected with the silica gel buffer pad. The protection frame, the protection plate, the air bag and the collapse box are arranged, which can effectively prevent vehicles from accidentally hitting the construction area, and on the other hand, the air bag and the silica gel buffer pad can effectively protect the vehicles, prevent the casualties in the vehicles, and when the device is hit, the gas in the gas cylinder is sprayed backward to form a reaction force, which can offset a part of the impact force of the vehicle and prevent the device from being hit open by the vehicle.
