Description
Technical field
The present invention relates to industrial reciprocating sieve, make the field especially for the large-scale linear vibrating screen of ore dressing industry.
Background technology
In the ore dressing industry, reciprocating sieve is a kind of common equipment, and its classification has: the straight line reciprocating sieve (as, CN2540235Y); Banana screen; High frequency sieve etc., it all exists: 1, noise is big; 2, power is big; 3, manufacturing cost height; 4, large-scale sieve manufacture craft requires high and can't reach desirable amount.
Can at present, make large-scale sieve, become the embodiment in the sector technical strength, in order to reach perfect performance, a lot of producers all select import equipment and importing technology equipment for use. but screen width since technical difficulty not yet above 4 meters.
Chinese patent literature discloses " a kind of large-scale vibrating screen of redundancy meshwork beams excitation " (CN1446642A), between the sieve plate of screen box both sides, the static-indeterminant mesh boom device is set, this device is distributed on the super quiet support plate by the requirement of many beams according to exciting force, form an inclusion body by many girders, connect into the exciting carrier with indeterminate support plate, the exciting power transmission shaft connects synchronous exciter unit, and the function of big exciting unit is substituted by synchronous exciting cell, constitutes net beam type excitor.It has proposed the design of a kind of large scale industry with sieve.But, still have the problem that structure is complicated, manufacturing cost is high.
Summary of the invention
The purpose of this invention is to provide that a kind of power is little, noise is little, can maximize, can modular novel vibrating screen.
The object of the present invention is achieved like this: a kind of novel vibrating screen, comprise screen frame, sieve plate, sieve plate is arranged in the screen frame versatilely: sieve plate is made up of by the row splicing by row a plurality of unit sieve plate, sieve plate all is fixed with support strip along bottom surface, left and right edge on delegation's length direction, rubber strip is installed down below the support strip, and following rubber strip contacts with screen frame; Also have sieve plate oscillating rectilinear motion driving mechanism: connecting rod one end is connected with bent axle, and crankshaft installed is on motor, and the connecting rod other end promotes slide block through drive link with the straight line of each row sieve plate and is connected;
Each left and right edge of unit sieve plate is equipped with lever transmission mechanism: lever connects a batten by U-shaped plate bottom and forms; Balance pivot is arranged on U-shaped plate the inner, is fixed with connecting pin on the balance pivot, and connecting pin is fixed on the block bearing inner ring, and block bearing is arranged on U-shaped plate the inner, and pedestal bearing outer race fixes through rest pad and screen frame; The gravity arm of lever end is arranged on U-shaped plate outer end, and another connecting pin is fixed on U-shaped plate outer end, and another bearing is installed on another connecting pin, and another bearing outer ring and support strip connect firmly; The lever arm of force end is arranged on the batten outer end, is fixedly connected with a pin on the bearing inner race, and batten outer end and pin connect firmly, and straight line promotes slide block and is fixed on the bearing outer ring;
Straight line promotes slide block and is slidingly matched with the line slideway that is fixed on the screen frame.
The principle of the invention is as follows: all there is the metal support bar at sieve plate length direction edge, to guarantee the uniformity of whole sieve plate motion, on two support strip, rubber strip is installed, utilize the elasticity of rubber strip to guarantee that the motion of sieve plate and screen frame have nothing to do, utilize the lever rotating mechanism to produce the power of the required direction of sieve plate, what promote the lever rotating mechanism is a straight line slide block, and linear slider is reciprocating under the crank mechanism of sieve afterbody drives, and reaches the purpose of sieve dehydration de-mediated.Because sieve plate is made up of the unit sieve plate, sieve plate can be assemblied to form, and does not have the restriction of width and length direction.
The purposes of reciprocating sieve is to be used for dehydration, de-mediated, and it is to make the oversize material throw and mouthful move to sieve to reach dehydration; Therefore the de-mediated purpose must make sieve plate produce and reach the discharging opening horizontal direction power of pointing to vertically upward.Existing sieve all is that the whole screen frame of vibrations achieves the goal, and so just brings aforesaid drawbacks.
In order to reach dehydration, de-mediated purpose, shake whole screen frame just for vibrating sieve plate, if can accomplish a vibrating sieve plate and the stressed relation that is equal to is arranged, also just solved the problems referred to above.
Reciprocating sieve of the present invention has upgraded the idea of existing reciprocating sieve fully, thereby has following characteristics and advantage:
1, noise is little;
2, power is little;
3, low cost of manufacture;
4, can maximize, but modularization, and convenient transportation.
