Description

A kind of vibration exciter
Technical field
The present invention relates to a kind of vibratory equipment, particularly a kind of vibration exciter.
Background technique
At present, vibratory equipment extensive use in industries such as the energy, metallurgy, pottery, building materials, chemical industry.Away from resonance, such vibratory equipment will pass through resonance region when start or shutdown when most of vibratory equipments were worked, and amplitude at this moment is the several times of working amplitude, and this phenomenon is very big to the effect on service life of vibratory equipment, and is big to the impact force of ground; Secondly, during the vibratory equipment start, because the quality and the throw of eccentric of eccentric mass are big, causes motor starts difficulty.Variable wheels vibration exciter is to utilize the acting in conjunction of pressure fluid and spring to change the position of eccentric mass, the excitation force of realizing vibration exciter from zero to peaked adjustment.The structure of existing variable wheels vibration exciter needs pressure fluid to get into from the both sides of vibration exciter respectively, so can only be applied on the common vibrating motor, can not on common vibration exciter, use.
Summary of the invention
The present invention has remedied the deficiency of existing technology, and a kind of vibration exciter is provided, and this vibration exciter makes vibratory equipment amplitude when start or shutdown little; Prolonged the life-span of equipment; Protected ground, reduced the startup load of motor simultaneously, and can on common vibration exciter, use.
Device of the present invention is; It comprises vibration exciter seat, bearing, main shaft, removable eccentric mass, eccentric mass cylinder, spring and land, and in the vibration exciter seat, land is arranged in the two ends of main shaft to main shaft through Bearing Installation; The eccentric mass cylinder is arranged on the land; Removable eccentric mass is assembled in the eccentric mass cylinder, and spring is installed between removable eccentric mass and the eccentric mass cylinder, and main shaft is provided with the passage of pressure fluid.Removable eccentric mass is provided with piston.Land is provided with fixed eccentric block.
Vibratory equipment when start, regulate pressure fluid and make removable eccentric mass move to the opposite of fixed eccentric block, starting electrical machinery afterwards; When treating that vibration exciter reaches desired speed; Regulate the position that pressure fluid changes removable eccentric mass again, thus the amplitude of adjustment vibratory equipment, during the vibratory equipment shutdown; Regulate pressure fluid and make removable eccentric mass move to the opposite of fixed eccentric block, turn off motor afterwards.
Compared with prior art, the present invention has following beneficial effect:
1, excitation force of the present invention is prone to regulate;
2, applied range of the present invention;
3, the present invention is prone to realize maximizing.
