The utility model discloses a convenient bed guardrail, through being formed with independent guardrail opening between two vertical columns of each guardrail main part, equivalent to setting the passable passageway on the left, right, front (or rear) three sides of bed body, and user can choose the guardrail opening direction freely according to the actual scene, and thoroughly get rid of the path limitation of "single -sided opening", simultaneously, three -sided guardrail frame covers the main activity area (such as left and right sides prevent rolling, front end prevent turning over and falling) of bed body, and the protection range is more comprehensive, to satisfy the double demand of user to security and use convenience.

The present disclosure relates to a scraper machine for rock wool collection, belonging to the technical field of industrial material conveying equipment, comprising a rack and a transmission mechanism arranged on the rack, the transmission mechanism comprising a driving sprocket arranged at the tail of the rack and a driven sprocket arranged at the head of the rack, the driving sprocket and the driven sprocket being provided with a transmission chain, and the middle part of the rack being provided with a bottom plate arranged horizontally with the rack, and a certain gap being maintained between the bottom plate and the transmission chain; the axial baffle arranged on the transmission chain enables the chain to only bend along the rotation of the sprocket, avoiding the central droop caused by the self-weight of the chain, and the sagging gravity is converted into the tension of the upper chain, so that the chain remains straight, thereby ensuring the constant gap between the scraper rod and the bottom plate and avoiding friction loss; the driving sprocket and the driven sprocket are arranged in a lower position, cooperating with the adjustable tensioning sleeve structure, and eliminating the energy loss caused by the friction of the traditional drag chain plate.
