Description
Technical field
The utility model belongs to screening plant technical field, particularly a kind of strong vibrating screen.
Background technology
The shaking device of vibratory sieve of the prior art is all be installed on sieve plate bottom, and the vibratory sieve of this kind of structure when mounted, is especially positioned at sieve plate bottom when changing vibrator, power transmission shaft or shaft coupling because of it, and in the middle of screen frame (unit), dismounting is inconvenience very.And be subject to washing away of long-time material due to the screen box base plate of vibratory sieve, easily occur heavy wear, maintenance process is loaded down with trivial details, improves production cost.Meanwhile, sieve-plate structure of the prior art mostly is netted sieve plate, and sieving time is long, inefficiency.
Utility model content
The purpose of this utility model is to provide a kind of strong vibrating screen, and the utility model structure is simple, and shaking device is installed simple, and screen box base plate is wear-resisting, and screening effect is good, and efficiency is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of strong vibrating screen, comprise support body, screen box and sieve plate, screen box is connected with support body by cushioning members, screen box inwall is connected with sieve plate by liner plate, be provided with vibrator in screen box above sieve plate, vibrator is connected with the motor outside screen box with shaft coupling by power transmission shaft, and described sieve plate is comb shape sieve plate, comb shape sieve plate is staggered by long grating and short grating and forms, and the cross section of grating is upside-down trapezoid; Screen box plate inner wall bottom sieve plate is provided with several quarter butt, and quarter butt end is sphere; Described liner plate comprises wearing plate and the substrate of one connection up and down, and substrate bottom surface is provided with reinforcement.
Preferably, described cushioning members is rubber spring.
Preferably, the sieve plate of several step arrangement is provided with in described screen box.
Preferably, described motor is arranged on motor frame.
Preferably, described substrate is steel plate.
The utility model is by shaking device of the prior art: motor, shaft coupling, power transmission shaft and vibrator are arranged on sieve plate top.When keeping in repair or install shaking device, the step of dismounting sieve plate can be saved, and operating space is large, consumes during shortening, overcomes the defect being inconvenient to when vibratory sieve of the prior art changes vibrator, power transmission shaft or shaft coupling dismantle.Adopt the liner plate of new structure: liner plate upper strata is wearing plate, lower floor is substrate simultaneously.Substrate is general steel plate, such layer structure design is that the wearing plate making way for upper strata directly contacts with material, because its wearability is high, therefore not easy to wear, long service life, but easily rupture due to it, quality is more crisp, so coordinate the substrate adopting general steel plate to make in lower floor, increase the pliability of liner plate entirety, substantially prolongs the service life of liner plate.
The utility model adopts rubber spring as cushioning members, and the noise produced when effectively reducing vibratory sieve work, optimizes production environment, simultaneously compared with in prior art as the long service life of the metal spring of cushioning members.
In order to improve the operating efficiency of vibratory sieve, the utility model uses the castor shape sieve plate of several step arrangement, and the grating of sieve plate is different in size, in " long-short-long-... .-is long " ordered state.First, long grating is different with the amplitude of short grating, improves the vibrating effect of screening materials carrying on sieve plate; Secondly, several sieve plate step arrangement, carries out several grades to material and repeatedly sieves, further increase screening effect.And the cross section of grating is upside-down trapezoid, make the shape that " sieve aperture " is little in upper shed, under shed is large that sieve plate is made up of two adjacent gratings, material is not easily blocked between grating.
In order to improve the abrasion resistant effect of screen box base plate, the utility model is novel is provided with several quarter butt on screen box base plate, quarter butt end is sphere: the stop being subject to the adjacent sphere of horizontal direction and quarter butt through the material of sieve plate when gliding along screen box base plate, part solid accumulation in the space be made up of sphere and screen box base plate, and is supplemented by the material continuing to glide; Another part material forms domatic continuation along above-mentioned stacking material and glides, and this makes the friction of material and screen box base plate change friction between material and material into, greatly reduces the wearing and tearing that flowable materials causes screen box base plate.When downslide material quantity reduces, the material be deposited in the space that is made up of sphere and screen box base plate supplements due to the continuation of the material that do not glide, and under self gravitation effect, glides from the space between sphere and screen box base plate.
Compared with prior art, tool has the following advantages the utility model: reasonable in design, and shaking device is installed, dismounting is simple, and screen box base plate abrasion resistant effect is good, and sieve plate carries out multi-stage, efficient screening to material and not easily by feed blocking.
