The utility model passes through to adopt the sieve nest underframe of unsettled design with the unsettled setting of whole sieve ship assembly, cooperate eccentric shaft and flexible supporting frames that inertia link and sieve ship assembly are sieved, the vibration source that on sieve ship assembly, is provided with, make material in sieve ship assembly, produce up-down vibration simultaneously, thereby realize before and after material is in the sieve ship, up and down, side-to-side movement, make material be not easy to make screen cloth to stop up, can reach the purpose of accurate screening by separating after the accurate classification of fineness requirement simultaneously.Adopt shock preventing device and inertia link to adopt flexible supporting frames to be connected between sieve ship assembly and the inertia link to have guaranteed that the sieve boatman does acutely and frame is steady with eccentric shaft, the vibration that plane transmission inertia force can be seesawed simultaneously, eccentric shaft mechanical force, vibrating motor produces passes to the sieve ship in the sieve ship assembly, guarantee the optimally sized of material in the screen cloth of sieve ship, can make particle by thickness grading, by finished product and impurity classification, grade by weight.The utility model can be used for powder classification in feed, food, chemical industry, the pharmaceuticals industry.
As improvement of the present utility model, described sieve ship assembly comprises the sieve ship and drops down plate, drops down plate and fixedlys connected with the inertia link, drops down between plate and the sieve ship to be tightly connected by the envelope band that is flexible coupling.Dropping down plate can make material descend along dropping down plate, flow to discharging opening, because stopping of the envelope band that is flexible coupling arranged, material can airborne dust, can be sealed in sieve ship and dropping down between the plate, in addition, the sieve ship in the sieve ship assembly with drop down plate split combination and solved original sieve ship under the effect of vibrating motor, resonance and noise that the large-area metal board plane that causes brings.
Described vibration source can be arranged on 1/3～1/5 place and close material inlet one end of the sieve ship length overall in the described sieve ship assembly; The sieve ship left and right sides is located or be arranged on to vibration source in the middle of also can being arranged on the sieve boat bottom.Can obtain to vibrate preferably separating effect, sieve aperture is difficult for stopping up.
For making the sieve ship assembly can excellent support, between inertia link and sieve nest underframe, balance can be set and prop up thick stick, described balance is propped up thick stick and is arranged on eccentric shaft one side, and two ends are hinged with inertia link and sieve nest underframe respectively up and down for it.
For avoiding the sieve pore blockade on the screen cloth, two-layer screen cloth up and down is set in the described sieve ship, be divided into some grids between the described two-layer screen cloth, be provided with cleaning piece or cleaning ball in the grid.When sieve ship when vibration, cleaning piece or cleaning ball roll, vibrate the cleaning sieve aperture back and forth, push and sieve being blocked in material on the sieve aperture, or break away from sieve aperture, and vibration screening makes sieve aperture clear and coherent again.
Described flexible supporting frames can be eccentric connecting axle, active link, cylinder column link or board-like column link.Above-mentioned several structure all has advantage simple in structure, easily manufactured.
