Abstract
The utility model relates to an amplitude variable sieving machine used for mines, which is composed of a motor, a vibrator, a sieve frame, a vibration spring and a machine frame. The utility model is characterized in that the machine is not provided with an eccentric balance-weight block on a belt pulley and a fly wheel of the vibrator and additionally provided two sets of independent eccentric balance-weight mechanisms which are respectively arranged on shaft journals arranged on both ends of a shaft of the vibrator. Because the eccentric balance-weight block adopts the elastic connection, the eccentric distance, the amplitude and the exciting force of the eccentric balance-weight block can be changed along with the size of centrifugal force. The utility model has the characteristics that the resonance phenomenon can not occur in the processes of starting and stopping; the operation is stable; the equipment is not easy to damage; sieve and screen mesh clogging phenomena can not appear, and the operation is stable, and furthermore, the utility model has multiple purposes. The machine can be used for the mines and can be used for other fields.
Description
Technical field
The utility model relates to oscillatory type screening machine new varieties.
Background technology
The existing oscillatory type screening machine that is used for the mine, be equipped with fixing eccentrically mounted weight piece on the belt pulley of its vibrator and the flywheel end face, during rotation, driving riddler by eccentrically mounted weight piece exciting force does, because of the eccentric throw of eccentrically mounted weight piece is changeless, so there is following drawback: the one, produce strong covibration in starting and the stopped process, it is more not steady to work, and easily causes device damage; The 2nd, easily produce and stop up sieve and screen cloth phenomenon, functional reliability is relatively poor.
Summary of the invention
The purpose of this utility model is to provide a kind of variable amplitude formula screening machine that can not produce resonance and stop up sieve and screen cloth phenomenon.
The utility model adopts following manner to achieve the goal: this machine is by motor, vibrator, screen frame, vibrating spring and frame are formed, on vibrator belt pulley and flywheel, do not establish the eccentrically mounted weight piece, set up two and overlap independently eccentrically mounted weight mechanism, be installed in respectively on the axle journal at vibrator shaft two ends, eccentrically mounted weight mechanism is by eccentric block, eccentric block, eccentric frame, pull bar, spring, nut and spring bearer plate are formed, it is hinged with the nut U-shaped end in the spring that eccentric frame side opening upper end is injected on pull bar top, use screw, nut is pressed in spring bearer plate on the spring upper surface, eccentric block is positioned on the eccentric block, eccentric block bight and eccentric frame lower hinge, the middle part is hinged with the pull bar lower end, because of eccentric block is that elasticity connects, so eccentric throw, amplitude, exciting force can change with the centrifugal force size, this machine of making is in starting, can not produce resonance in the stopped process and stop up sieve and screen cloth phenomenon, stable working, reliably.
Characteristics of the present utility model: the one, can not produce covibration in starting and the stopped process, stable working makes equipment not fragile; The 2nd, can not produce and stop up sieve and screen cloth phenomenon, reliable operation; The 3rd, multipurpose, this machine also can be used for other field except that being used for the mine.
