A kind of vibration box of brick making machine
Technical field
The invention belongs to the block machine technical field, relate in particular to a kind of last vibrating device of block machine.
Background technology
Vibrating device is a vitals on the block machine, makes material compacting moulding in the moulding box by vibration.The vibrating device of existing block machine comprises a casing, two eccentric shafts are housed in the casing and are located at the eccentric block of the identical weight on two eccentric shafts respectively, be connected with synchromesh gear between two eccentric shafts, eccentric shaft, eccentric block and synchromesh gear all place one to be fixed in the casing of shake table downside, one end of two eccentric shafts passes this casing respectively, be respectively equipped with belt pulley on two axle heads, motor is done the synchronous backward rotation by the eccentric block that belt pulley drives on two eccentric shafts, thereby produces vibration.The problem that this eccentric shaft type vibrating bin exists is: eccentric throw is little, the use rotating speed is low, and starting reactance is apart from big, and starting of oscillation is slow, and the starting of oscillation time is long.
Summary of the invention
The purpose of this invention is to provide a kind of improved vibration box of brick making machine, it is little that this improved vibration box of brick making machine preferably resolves eccentric shaft type vibrating bin eccentric throw, uses rotating speed low, and starting reactance is apart from big, and starting of oscillation is slow, the problem that the starting of oscillation time is long.
The objective of the invention is to be achieved through the following technical solutions, this vibration box of brick making machine comprises that being fixed in one on the shaking platform vibrates casing, two main shafts and two power transmission shafts are housed in the described casing, one end of described two main shafts passes casing, be provided with belt pulley in its end, described two power transmission shafts be positioned at two main shafts the inboard, a synchromesh gear respectively is housed on described main shaft and the power transmission shaft, and it is meshing mutually, rotate with the synchronous backward of realizing two main shafts, a ring flange respectively is equipped with in the rear end of two main shafts, is fixing eccentric block on the both sides end face of synchromesh gear on described main shaft and ring flange.
Fixing 2 eccentric blocks with the M16 socket cap screw respectively on the both sides end face of described each synchromesh gear and ring flange.
The end of described main shaft and power transmission shaft is provided with bearing with vibration casing junction.
The cabinet exterior of described main shaft, power transmission shaft and bearing junction is provided with oil sealing.
Drive two vibrating bin main shaft synchronous backwards by motor or hydraulic motor by belt pulley during work and rotate, thereby the vertical orientation of realizing moulding machine vibration platform and moulding box vibrates.
Beneficial effect of the present invention:
1, increased eccentric throw, starting reactance is apart from little, and starting of oscillation is fast, and starting of oscillation, failure of oscillation time weak point only have 0.2 second, and moment can meet the requirements of vibration rotating speed and frequency, has shortened the block forming cycle, can enhance productivity.
2, can use high rotational speed, more than 5500r/min, thereby realize dither and bigger exciting force, exciting force satisfies building block high pressure, highly dense solidity production requirement up to 150kN.
3, shaking platform and vibrating bin split manufacturing assembling, easy for assembly, disassembly and maintenance.

Among the figure: 1, belt pulley 2, oil sealing 3, bearing 4, synchromesh gear 5, main shaft 6, ring flange 7, eccentric block 8, power transmission shaft 9, shaking platform 10, vibration casing
The specific embodiment
As Fig. 1, shown in Figure 2, this vibration box of brick making machine comprises that being fixed in one on the shaking platform 9 vibrates casing 10, two main shafts 5 and two power transmission shafts 8 are housed in the casing 10, one end of two main shafts 5 passes casing, be provided with belt pulley 1 in its end, two power transmission shafts 8 be positioned at two main shafts 5 the inboard, a synchromesh gear 4 respectively is housed on main shaft 5 and power transmission shaft 8, and it is meshing mutually, rotate with the synchronous backward of realizing two main shafts, a ring flange 6 respectively is equipped with in the rear end of two main shafts 5, is fixing 2 eccentric blocks 7 with the M16 socket cap screw respectively on the both sides end face of each synchromesh gear 4 and ring flange 6.End at main shaft 5 and power transmission shaft 8 is provided with bearing 3 with vibration casing 10 junctions, is provided with oil sealing 2 on the cabinet exterior of main shaft 5, power transmission shaft 8 and bearing 3 junctions.
Drive two vibrating bin main shaft 5 synchronous backwards by motor or hydraulic motor by belt pulley 1 during work and rotate, thereby the vertical orientation of realizing moulding machine vibration platform and moulding box vibrates.
