Vibration box of brick making machine

Abstract

The invention discloses a vibration box of a brick making machine, which comprises a vibration box body fixed on a vibration platform, wherein two main shafts and two transmission shafts are arranged in the box body; one end of the two main shafts passes through the box body; belt pulleys are arranged at end parts of the main shafts; the main shafts and the transmission shafts are provided with asynchromesh gear respectively, and the synchromesh gears are meshed mutually; the rear ends of the two main shafts are provided with a flange plate respectively; and eccentric blocks are fixed on thesynchromesh gears on the main shafts and end faces of both sides of the flange plates. When the vibration box operates, two main shafts of the vibration box are driven by a motor or a hydraulic motorthrough the belt pulleys to make synchronous reverse rotation, so that the vertical directional vibration of the vibration platform of the brick making machine and a casting box is realized. The vibration box has the advantages of large excentricity, small starting drag torque, quick vibration starting, short time of vibration starting and vibration stop and large exciting force.

Description

technical field [0001] The invention belongs to the technical field of block forming machines, and in particular relates to an upper vibration device of a block forming machine. Background technique [0002] The vibration device is an important part of the block forming machine, which makes the materials in the mold box compact and form through vibration. The vibrating device of the existing block forming machine includes a box body, two eccentric shafts and eccentric blocks of the same weight respectively arranged on the two eccentric shafts are housed in the box body, a synchronous gear is connected between the two eccentric shafts, The eccentric shaft, eccentric block and synchronous gear are all placed in a box fixed on the lower side of the vibrating table. One end of the two eccentric shafts passes through the box respectively. There are pulleys on the two shaft ends, and the motor drives the two shafts through the pulleys. The eccentric block on the root eccentric sh...
