Abstract
The invention relates to a variable force wheel applied to vibrating screen equipment. The variable force wheel is arranged on shock excitation blocks at two ends of a vibration motor of the vibrating screen, comprises a shell, a cylinder component and an air pipe component, and is characterized in that the shell is a rigid shell of the variable force wheel; the cylinder component consists of a spring, a piston and a cylinder; one end of a spring is fixed in the shell, and the other end of the spring is connected with the piston; the piston and the cylinder form a closed space; the piston freely slides in the cylinder body along the moving direction of the spring; the air pipe component is positioned on the outer side of the shell and consists of air pipes, a support and a rotary joint; the support is vertically fixed to the position of the center of a circle of the shell; one end of the air pipe is fixed on the support, and the other end of the air pipe is fixed on the cylinder; and the rotary joint is arranged on the support through a bearing and is connected with another air pipe. According to the device, the amplitude of the vibrating screen can be adjusted through inflation and deflation, the operation is easy and convenient, and the working efficiency of the vibrating screen is improved; and moreover, the vibrating screen is stable in the start and stop process, and the service life of the vibrating screen is prolonged.
Description
Technical field
The present invention relates to a kind of mechanical device, particularly be applied in the mechanical device of the adjustment amplitude on the vibratory sieve equipment.
Background technology
In the graded operation of industrial departments such as mine, building materials, chemical industry, shaker operation personnel need constantly adjustment vibratory sieve amplitude, make vibratory sieve keep optimum Working.Tradition vibratory sieve equipment does not have a kind of device of adjusting amplitude variations in working order down; So in operation process, can not adjust amplitude; Must shut down and could adjust the vibratory sieve amplitude, each shutdown can only be carried out an amplitude adjustment, and needs repeatedly to shut down and adjust amplitude repeatedly and just can reach the best effort effect; Such mode of operation has not only increased labor intensity of operating personnel, also causes operating efficiency significantly to reduce.
Secondly, when vibratory sieve during through resonance zone, when the amplitude of vibratory sieve is operate as normal 4 to 7 times, service life of vibratory sieve has been shortened in vibratory sieve excessive easy damage because exciting force is loaded greatly.
Summary of the invention
Lack a kind of device of adjusting amplitude variations in working order down in order to solve vibratory sieve equipment; Labor intensity of operating staff is big, operating efficiency low and the technological deficiency of vibratory sieve shortening in service life thereby cause, and proposes a kind of variable wheels of vibratory sieve that is applied to vibratory sieve.
The variable wheels of vibratory sieve of the present invention is installed in bolt on the exciting piece at shaker vibration motor two ends, comprises housing, cylinder assembly, tracheae assembly, it is characterized in that:
Housing is the rigid cylindrical shell of the variable wheels of vibratory sieve, built-in cylinder assembly;
Cylinder assembly is by spring, piston, and cylinder body is formed, and spring one end is fixed in the housing, and the other end is connected with piston, and piston and cylinder body constitute enclosure space, and piston is free to slide along the spring direction of motion in cylinder body;
The tracheae assembly is positioned at hull outside, is made up of tracheae, bearing and swivel joint, and the bearing vertical fixing is in the home position of housing; Tracheae one end is fixed on the bearing, and the other end is fixed on the cylinder body, and swivel joint is installed on the bearing through bearing; When the variable wheels of vibratory sieve rotated with vibrating motor, swivel joint was fixed, and swivel joint connects another tracheae; Cylinder body, swivel joint and bearing have passage, make air form airtight path at the gentle pipe of cylinder body.
The variable wheels of vibratory sieve of the present invention can be realized the adjustment to the vibratory sieve amplitude through charging and discharging gas, and is simple to operation, improved the vibratory sieve operating efficiency, alleviated labor intensity of operating personnel.In addition, use the vibratory sieve startup-shutdown process of the variable wheels of vibratory sieve more steady, and greatly reduce the destruction dynamics of resonance to vibratory sieve, the service life of having improved vibratory sieve.

The specific embodiment
Embodiment 1: the variable wheels of vibratory sieve comprises housing 1, cylinder assembly, tracheae assembly, and housing 1 is the rigid cylindrical shell of the variable wheels of vibratory sieve, built-in cylinder assembly; Cylinder assembly is by spring 2, piston 3, and cylinder body 4 is formed, and spring 2 one ends are fixed in the housing 1, and the other end is connected with piston 3, and piston 3 faces of cylinder are equipped with seal, is free to slide along spring 2 directions of motion in the cylinder body 4, constitutes enclosure space with cylinder block 4; The tracheae assembly is positioned at housing 1 outside, is made up of tracheae 5, bearing 6 and swivel joint 7, and bearing 6 vertical fixing are in the home position of housing 1; Tracheae 5 one ends are fixed on the bearing 6; The other end is fixed on the cylinder body 4, and swivel joint 7 is installed on the bearing 6 through bearing, when the variable wheels of vibratory sieve rotates with vibrating motor; Swivel joint 7 is fixed; Swivel joint 7 connects another tracheae 5, and cylinder body 4, swivel joint 7 and bearing 6 have passage, makes air form airtight path at cylinder body 4 and tracheae 5.Swivel joint 7 external electrical control gears during use charge and discharge the whole cylinder internal gas pressure of controlled atmosphere through control, reach the purpose of control amplitude.
When the variable wheels of vibratory sieve was installed, the eccentric position of its piston 3 positions and vibrating motor exciting piece was consistent, promptly the eccentric position of vibrating motor exciting piece down, the piston 3 of the variable wheels of vibratory sieve is also down.When inflating for through electrical control gear the variable wheels of vibratory sieve, inner pressure of air cylinder increases, and gas promotes piston 3 compression springs 2 and moves toward the opposite direction of the eccentric position of vibrating motor exciting piece, and amplitude reduces; Otherwise when exitting for through electrical control gear the variable wheels of vibratory sieve, inner pressure of air cylinder reduces, and spring 2 promotes the direction motion of pistons 3 toward the eccentric position of vibrating motor exciting pieces, and amplitude increases.Feed cylinder pressure between 0～0.5 MPa, the amplitude that different gas pressures is corresponding different.When feeding gas pressure when being zero, the equipment amplitude is maximum, and when feeding gas pressure when being 0.5 MPa, the equipment amplitude is minimum.
