Summary of the invention
The purpose of this utility model is to provide a kind of vibratory sieve, can realize when vibratory sieve is worked fixing secondary vibration damping, during maintenance along the function of rail moving.
To achieve these goals, the utility model has adopted following structure: a kind of vibratory sieve, include vibratory sieve lower support beam and the bracket for vibrating screen of shaker body, support shaker body, wherein, between described bracket for vibrating screen and vibratory sieve lower support beam, be removably provided with secondary vibration absorber or vibratory sieve mobile device.
Further, described secondary vibration absorber includes secondary shock-absorbing spring bearing, secondary shock-absorbing spring, and secondary shock-absorbing spring top connecting plate, described secondary shock-absorbing spring bearing is removable installed on vibratory sieve lower support beam by connecting bolt, described secondary shock-absorbing spring is arranged on described secondary shock-absorbing spring bearing, and described secondary shock-absorbing spring top connecting plate is removably connected in secondary vibration absorber the bottom of bracket for vibrating screen.
Further, described vibratory sieve mobile device includes movable rail, bracket for vibrating screen roller, described bracket for vibrating screen roller is removable installed in bracket for vibrating screen below by bolt, described movable rail is removable installed on vibratory sieve lower support beam by connecting bolt and pressing plate, thereby realize vibratory sieve, by support roller, along movable rail, trapped orbit, moves.
Adopt the vibratory sieve of said structure, during work, adopted secondary vibration damping only to do a vibration damping compared with original vibratory sieve and can reduce vibratory sieve and be delivered to the power of scratching on brace summer, solved the Cable Power Computation problem of many support vibratory sieve frameworks; Meanwhile, when maintenance, the function moving while adopting track to realize vibratory sieve maintenance, has facilitated the maintenance of vibratory sieve greatly.

The specific embodiment
In order better to understand the purpose of this utility model, below in conjunction with background of the present utility model, accompanying drawing and actual condition, structure and function to vibratory sieve described in the utility model are described in detail.
When the utility model is worked at vibratory sieve, by its bearing bottom roller and dismantling of track, secondary vibration damping holder and secondary shock-absorbing spring are installed, the secondary vibration damping while realizing vibratory sieve work, the transmission of oscillating load while more effectively reducing vibratory sieve work; When vibratory sieve overhauls, the secondary vibration damping holder of installing and secondary shock-absorbing spring are removed, be replaced by original bearing roller and track, realize vibratory sieve and move maintenance.
From Fig. 1 to Fig. 5, described vibratory sieve described in the utility model includes vibratory sieve 7, supports vibratory sieve lower support beam 1 and the bracket for vibrating screen 5 of vibratory sieve 7, between described bracket for vibrating screen 5 and vibratory sieve 7, be provided with one time shock-absorbing spring 6, between described bracket for vibrating screen 5 and vibratory sieve lower support beam 1, be removably provided with secondary vibration absorber or vibratory sieve mobile device.From Fig. 1 to Fig. 3, described removably secondary vibration absorber includes secondary shock-absorbing spring bearing 9, secondary shock-absorbing spring 10, and secondary shock-absorbing spring top connecting plate 11, described secondary shock-absorbing spring bearing 9 is arranged on vibratory sieve lower support beam 1 by connecting bolt 8, described secondary shock-absorbing spring 10 is arranged on described secondary shock-absorbing spring bearing 9, and described secondary shock-absorbing spring top connecting plate 11 is connected in secondary vibration absorber the bottom of bracket for vibrating screen 5; From Fig. 4 and Fig. 5, described vibratory sieve mobile device includes movable rail 3, bracket for vibrating screen roller 4, described bracket for vibrating screen roller is arranged at bracket for vibrating screen 5 belows by bolt 8, described movable rail 3 is fixed on vibratory sieve lower support beam by connecting bolt and pressing plate, thereby realize vibratory sieve, by support roller 4, along movable rail 3, trapped orbit 2, moves.
During the work of the utility model vibratory sieve, secondary shock-absorbing spring bearing 9 is connected with vibratory sieve lower support beam 1 by connecting bolt 8, form entirety, again secondary shock-absorbing spring 10 is installed on secondary shock-absorbing spring fastening 9, finally by secondary shock-absorbing spring top connecting plate 11, be connected with the bracket for vibrating screen 5 of vibratory sieve superstructure, secondary shock-absorbing spring 10 and a shock-absorbing spring 6 are jointly worked when vibratory sieve is worked, realize twice damping.
In vibratory sieve installation in place, when maintenance,, remove secondary shock-absorbing spring fastening 9 by vibratory sieve jack-up with jack, are replaced by movable rail 3 and roller 4, make the vibratory sieve 7 can be along rail moving.Specific practice is that secondary shock-absorbing spring fastening 9, secondary shock-absorbing spring 10, secondary shock-absorbing spring top connecting plate 11 are disassembled, movable rail 3 is fixed on vibratory sieve lower support beam 1 by pressing plate with connecting bolt 8, then bracket for vibrating screen roller 4 use bolts are installed on to bracket for vibrating screen 5, so, vibratory sieve can move along movable rail 3, trapped orbit 2 by support roller 4.
Adopted the vibratory sieve of above-mentioned changeable type structure, only done the situation of a vibration damping than original vibratory sieve, secondary vibration damping has reduced vibratory sieve and has been delivered to the power of scratching on brace summer, has solved the Cable Power Computation problem of many support vibratory sieve frameworks.Reduce the cross section of brace summer, reduced the cost of support frame, saved lower section frame space; When the vibratory sieve of this structure overhauls, can move freely, greatly facilitate maintenance process; Can secondary vibration during the work of this vibratory sieve, during maintenance, can move, solved the two problem that can not take into account of existing vibratory sieve.It is convenient that the utility model vibratory sieve transportable bearing when when work secondary vibration damping, maintenance transforms.
The advantage of vibratory sieve described in the utility model: 1, when work adopts secondary vibration damping only to do a vibration damping compared with original vibratory sieve can to reduce vibratory sieve and be delivered to the power of scratching on brace summer, solve the Cable Power Computation problem of many support vibratory sieve frameworks; Reduce the cross section of brace summer simultaneously, reduced the cost of support frame, saved lower section frame space.
When 2, the utility model vibratory sieve overhauls, the function having moved while using track to realize vibratory sieve maintenance, has facilitated the maintenance of vibratory sieve greatly;
3, the utility model realized vibratory sieve when work can secondary vibration damping, transportable function during maintenance, both problems that can not take into account that therefore solved existing vibratory sieve.
4, the conversion of the utility model from secondary vibration damping duty to mobile inspecting state is convenient, easy to operate.
The above is only a kind of specific embodiment of vibratory sieve described in the utility model; it should be pointed out that for those skilled in the relevant art, under the premise without departing from the principles of the invention; trickle modification and the improvement made, also should be considered as belonging to protection domain of the present utility model.
