The utility model provides a kind of rehabilitation nursing vibration recuperation bed, including chassis, a layer of rubber pad is laid above the chassis, multiple independent bed boards are laid above the rubber pad;The space for installing vibration plate is equipped in the chassis, vibrator is installed in the central position above vibration plate, there is a side plate in each side above vibration plate, there is an arc plate for supporting cross bar above side plate;Through hole for transmission plate is passed through is formed in one side of cross bar, embedding slot for transmission plate is embedded in the other side of cross bar, opening for transmission plate is also formed in the inside of each bed board, and is passed through bed board inside opening to be connected by transmission plate to pass into the through hole and embedding slot of cross bar.This structure design makes it possible to selectively connect certain bed board with vibration plate, so as to accurately transmit vibration to specific bed board.

This utility model discloses a railway sleeper production pouring and vibrating device in the field of pouring and vibrating device technology. It includes a railway sleeper pouring mold, a movable vehicle on top of the mold, and a pouring and vibrating assembly inside the movable vehicle. The pouring and vibrating assembly includes a lifting base plate, limit slots on both sides of the lifting base plate, a pouring vibrator at the bottom of the lifting base plate, and a pouring vibrator rod at the bottom of the vibrator. Connecting seats are installed at the four inner corners of the lifting base plate and the vibrator. In this railway sleeper pouring and vibrating device, when the lifting base plate lowers the pouring vibrator rod into the railway sleeper pouring mold, the vibration generated by the electrically powered pouring vibrator rod can fully compact the concrete inside the mold. With the help of the horizontal displacement function of the movable vehicle, the pouring vibrator rod can uniformly compact the concrete at different locations within the mold, effectively improving the uniformity of concrete density and enabling mass production of railway sleepers.

The utility model discloses a food processing machine with a good damping effect, which relates to the field of life electric appliances and comprises a machine base internally provided with a motor and a smashing cup detachably arranged on the machine base, a smashing device in transmission connection with the motor is arranged in the smashing cup, and a water tank communicated with the smashing cup is further arranged on the machine base. The machine base comprises a machine shell, a mounting part is arranged on the inner wall of the machine shell, the water pump is further sleeved with a flexible part, and the water pump is fixed to the mounting part through the flexible part, so that vibration generated in the working process of the water pump is effectively absorbed, transmission of the vibration to the mounting part is effectively reduced, and then vibration of the whole machine shell is reduced; the resonance phenomenon in the working process is avoided, the stability of machine operation is improved, meanwhile, flexible isolation of the water pump and the machine shell is achieved through the flexible piece, and therefore the situation that the water pump directly collides with the installation part to generate collision noise when working is effectively avoided, noise reduction is achieved, and the noise reduction effect is improved.

This invention belongs to the field of power equipment technology, and particularly relates to a towable mobile protective assembly, comprising: a base with lifting lugs on its side walls and a set of wheels on its bottom; a protective box mounted on the base; and an internal circulation mechanism housed within the protective box for internal air circulation and heat dissipation of the high and low voltage switchgear. The base has a hollow structure, and a lightweight support unit is installed inside. This internal circulation heat dissipation mode prevents external air from directly entering the equipment, effectively preventing contamination from dust, moisture, and other impurities. The lightweight support unit of the base effectively reduces the burden of movement.
