Preferably, the length of the second bed board is 2 times of the length of the first bed board, and the height of the bed frame is smaller than the length of the second bed board.
Preferably, the first bed board, the second bed board and the bed frame are hinged through hinges and can be movably turned over.
Preferably, the bottom plate is provided with air holes for allowing air to enter.
Preferably, a cushion block is further arranged below the bottom plate, and the cushion block and the bottom plate are fixed through expansion screws, so that ventilation of the bottom plate is facilitated.
Preferably, the guide rail is a triangular guide rail, and a triangular ring groove corresponding to the triangular guide rail is arranged on the outer peripheral surface of the roller, so that the roller cannot deviate during rolling.
Preferably, the middle of the moving frame is provided with two cross beams, the cross beams are welded with motor plates, and the speed reducer is mounted on the motor plates and is convenient to mount.
Preferably, the number of the rollers is two, and the rollers are respectively arranged on two sides of the movable frame.
Preferably, the bearing box is in an inverted U shape, and the bearing box is welded on two sides of the movable frame.
Preferably, the first bed board and the second bed board are prepared from the following raw materials in parts by weight: 20-30 parts of straw, 20-30 parts of China fir powder, 10-15 parts of nitrile rubber, 10-15 parts of cement, 10-12 parts of polyvinyl chloride, 5-7 parts of epoxy resin, 6-8 parts of glass fiber, 3-5 parts of perlite, 1-3 parts of sodium silicate, 1-3 parts of basalt fiber, 4-6 parts of dibutyltin maleate, 1-3 parts of antimony trioxide, 2-4 parts of ceramsite, 1-2 parts of neodymium oxide, 2-3 parts of tea tree essential oil, 3-5 parts of a high-efficiency water reducing agent, 3-5 parts of borax and 60-80 parts of water.
Another technical problem to be solved by the present invention is to provide a method for preparing a first bed board and a second bed board, comprising the following steps:
