Detailed description of the invention
An embodiment of a kind of energy saving vibrating sieve of the utility model is as shown in Fig. 1 ~ Fig. 7, upper sieve nest 4, lower sieve nest 5 that involving vibrations sieves base 1, is supported on the frame 3 on vibratory sieve base 1 and is disposed on up and down in frame 3 by shock-absorbing spring 2, vibratory sieve base 1, shock-absorbing spring 2 and frame 3 are configured for the bracing or strutting arrangement supporting sieve nest.
Upper sieve nest 4 and lower sieve nest 5 are rectangle, and be inclined relative to horizontal layout, respective corner location is respectively arranged with ball-frame carriage 7.Ball-frame carriage 7 comprises sieve nest bearing 8, supporting seat 10 and the rolling support ball 9 between described sieve nest bearing 8 and supporting seat 10.Sieve nest bearing 8 is the trench structure that Open Side Down and top is provided with hinged seat, and sieve nest can be bolted on hinged seat.Supporting seat 10 is provided with opening up V-shaped groove, for supporting and detent ball 9.Ball 9 is point cantact with the sidewall of V-shaped groove and the bottom surface of sieve nest bearing 8.By ball-frame carriage 7, upper sieve nest 4 and lower sieve nest 5 can guiding movements in the horizontal direction.In the horizontal direction in guiding movement process, sieve nest bearing 8 and supporting seat 10 all in linear point cantact, reduce the loss between contact position, long service life with ball 9 significantly, and V-shaped groove can ensure the stability of ball 9, ensure the accuracy of guiding.
As shown in Figure 1, Figure 2 and Figure 3, the middle part of the side that upper sieve nest 4 is vertical with horizontal direction with lower sieve nest 5 has been connected respectively upper vibrator and lower vibrator, and upper vibrator and lower vibrator are separately positioned on the both sides in rack level direction.Due to visual angle relation, the vibrator shown in Fig. 2 is not connected on corresponding sieve nest, but it will be appreciated by those skilled in the art that each vibrator should be connect with corresponding sieve nest.Lower vibrator is supported and fixed on ground lower vibrator bearing 24, and upper vibrator is supported and fixed on the upper exciter support 23 of Plate Welding, and upper exciter support 23 is fixed in the frame 3 of energy saving vibrating sieve.Upper vibrator and lower vibrator include transmission rod 18, for the directional support 12 that leads in the horizontal direction to transmission rod 18 with for driving the eccentric wheel 17 of transmission rod 18 guiding movement.Directional support 12 is ball-type directional support 12, comprise directional support base 11, supply the jack that transmission rod 18 plugs and the directional support ball 13 be arranged in jack, strictly can limit the radial displacement of transmission rod 18, the direction of transfer of fixing horizontal dynamic load well, and the contact that can reduce significantly between transmission rod 18 and bearing, and then reduce friction, save energy consumption.The end face of described eccentric wheel 17 is provided with annular groove 21, and described transmission rod 18 is provided with the drive bearing 22 for embedding in described annular groove 21, and the cell wall of described driving member and described annular groove 21 is rotatably assorted and is slidably matched.During work, eccentric wheel 17 and motor shaft 16 are spin-ended fixing and driven by motor 15, and motor 15 is controlled by frequency converter 14, drives transmission rod 18 pairs of sieve nests to apply horizontal loads.Transmission rod 18 is vibrator output towards one end of sieve nest, this end end is provided with helical spring baffle plate 19, one end as the helical spring 20 of elastic device to be set on transmission rod 18 and to fix with helical spring baffle plate 19, the other end and the sieve nest of helical spring 20 are fixed, thus realize being in transmission connection between vibrator output and sieve nest.
During use, motor 15 is switched on power, and adjust frequency converter 14 as required to regulate the operating frequency of motor 15.In screening operation process, material drops into from feed hopper 6, and each motor 15 is with movable eccentric wheel 17 to rotate, and is made to go up sieve nest 4 accordingly by the impact load of different frequency or lower sieve nest 5 produces periodic horizontal displacement by transmission rod 18 and helical spring 20.When reaching the limit of setting towards the displacement of a direction, due to the stretching action of helical spring 20, the pulling force that sieve nest is subject to helical spring 20 will be got back to initial position along opposite direction and continue mobile extrusion spiral spring 20, and at this moment transmission rod 18 will transmit again new impact load by helical spring 20 and then drive sieve nest to form new displacement.
The amplitude of the horizontal vibration load of system input realizes adjustment by following two kinds of methods: one is the eccentric throw by adjusting eccentric wheel 17, and eccentric throw is larger, and transmission rod 18 stroke is larger, and load amplitude is larger; Eccentric throw is less, and the stroke of transmission rod 18 is less, and load amplitude is less.Two is that stiffness coefficient is larger, and load amplitude is larger, and stiffness coefficient is less, and load amplitude is less by changing helical spring stiffness coefficient to realize.
