Abstract
The utility model belongs to improvement of a self-centering inertia vibrating screen structure, and in particular relates to an eccentric distance adjustable vibration exciter for a self-centering inertia vibrating screen. According to the eccentric distance adjustable vibration exciter, a vibration exciter is arranged on a main shaft of the inertia vibrating screen; according to a structure of the vibration exciter, two regulating grooves which are parallel to each other are formed on a spoke plate of a disc-shaped vibration excitation wheel with an annular boss on the outer edge and are positioned on two sides of the central line of the vibration excitation wheel; two mounting holes are formed in a vibration excitation block, and space between the two mounting holes is equal to space between the two regulating grooves; the vibration excitation block is arranged on the spoke plate of the vibration excitation wheel by fixed bolts; a cylindrical countersink screw hole is formed in the cylindrical surface of the annular boss of the vibration excitation wheel in the radial direction; and a cylindrical head inner hexagonal screw arranged in the cylindrical countersink screw hole is matched with a regulating screw hole which is opposite to the vibration excitation block. The eccentric distance adjustable vibration exciter is reasonable and simple in structure, reliable in connection, low in manufacturing cost and long in service life, and the eccentric distance of the vibration excitation block on the vibration excitation wheel is convenient to regulate and large in regulating range and can meet the requirements of production.
Description
Technical field
The utility model belongs to the improvement of self centering inertial oscillation sieve structure, particularly a kind of vibration exciter of self centering inertia vibrating screen adjustable eccentric distance.
Background technology
The self centering inertia vibrating screen is compared with centrifugal sieving machine, has the output height, and screening efficiency is high, energy savings, and the advantage of long service life is widely used in the production of sandstone material, also is used for the screening of railroad ballast and the processing of mine ore.The self-centering inertia vibrating screen adjustment power of using at present that impulses adopts frequency modulation motor and attached control panel thereof to change rotating speed of motor and realizes that with high content of technology, cost is high.Also have through the position of adjustment eccentric block and realize adjusting the power that impulses; But eccentric block adopts relatively-stationary adjustment connecting hole to be connected through bolt with the wheel that impulses; The eccentric throw of adjustment eccentric block is very inconvenient, and being limited in scope of adjustment, and can not meet the needs of production.
Summary of the invention
The purpose of the utility model is to provide a kind of vibration exciter of self centering inertia vibrating screen adjustable eccentric distance, and it is rational in infrastructure, connects reliable; Adjusting impulse piece impulse the wheel on eccentric throw easy to adjust; Adjustable range is big, can meet the needs of production, and also simple in structure; Low cost of manufacture, long service life.
The purpose of the utility model is achieved in that a kind of vibration exciter of self centering inertia vibrating screen adjustable eccentric distance; On the main shaft of inertia vibrating screen, vibration exciter is installed; The structure of vibration exciter is for being provided with the two parallel regulating tank on the discoid wheel former that impulses that has the annulus boss in outer rim; Article two, regulating tank is positioned at the wheel center line both sides that impulse; The spacing that two installing holes are being set on the piece that impulses equates with the spacing of two regulating tanks; Through set bolt will impulse piece be installed in impulse the wheel the wheel former on, impulse the wheel the annulus boss face of cylinder on cylinder countersunk head screw radially is being set, the hexagonal screw rod matches with the adjusting screw of the piece opposite position that impulses in the socket cap of in cylinder countersunk head screw, installing.
When the utility model adjustment impulses the eccentric throw of piece; Only need unclamp and being installed in fixedly impulse two set bolts of piece of the wheel former that impulses; Adjusting impulses and takes turns hexagonal screw rod in the socket cap of installing in the screw of the annulus boss face of cylinder; The piece that impulses is moved along regulating tank, and after adjusting to the right place, fastening set bolt gets final product.The adjusting distance that piece moves that impulses, the scope of regulating the power that impulses is big.The utility model has been realized impulsing piece at the eccentric position that impulses on taking turns according to the quality of screening material and Flow-rate adjustment, makes the power of impulsing of vibratory sieve adapt to various material screening work.The utility model is rational in infrastructure, connects reliably, and it is easy to adjust in the eccentric throw that impulses on taking turns to regulate the piece that impulses, and adjustable range is big, has satisfied the needs of producing, and simple in structure, low cost of manufacture, long service life.

The specific embodiment
A kind of vibration exciter of self centering inertia vibrating screen adjustable eccentric distance; Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6; On the main shaft of inertia vibrating screen, vibration exciter is installed; The structure of vibration exciter is for being provided with two parallel regulating tank 7 on discoid wheel 1 former that impulses that has annulus boss 4 in outer rim; Article two, regulating tank 7 is positioned at the wheel 1 center line both sides that impulse, and the spacing that two installing holes 9 are being set on the piece 2 that impulses equates with the spacing of two regulating tanks 7, is installed in to impulse and takes turns on 1 the wheel former through set bolt 3 piece 2 that will impulse; On annulus boss 4 faces of cylinder of wheel 1 that impulse, cylinder countersunk head screw 6 is being set radially, hexagonal screw rod 5 matches with the adjusting screw 8 of piece 2 opposite positions that impulse in the socket cap of in cylinder countersunk head screw 6, installing.What impulse piece 2 is shaped as tabular of oval shape.The piece 2 that impulses of the utility model can manufacture that shape is identical, and weight differs, and plurality of specifications realizes seriation, and standardization is to satisfy the screening of various materials.
