Detailed description of the invention:
Below in conjunction with the accompanying drawings this utility model is done and further explain.
As shown in Figures 1 to 4, a kind of modular of the present utility model becomes span and becomes amplitude large-scale vibrating screen, including screen box 1, described screen box 1 includes the two pieces of sieve box side plate 1-1 being oppositely arranged, compass screen surface 7 is fixed in case side plate 1-1 lower end, constituted the agent structure of screen box 1 by sieve box side plate 1-1 and compass screen surface 7, one end of screen box 1 is feeding end 6, and the other end of screen box 1 is exhaust end 8.
Case side plate 1-1 is provided with horizontal draw-in groove 11, is provided with two excitation beam of vibrations 3 between two pieces of sieve box side plate 1-1, and the wherein feeding end 6 near screen box 1 of two excitation beam of vibrations 3, another root is near the exhaust end 8 of screen box 1.Excitation beam of vibration 3 two ends are provided with vertical draw-in groove 12, are penetrated in horizontal draw-in groove 11 and vertical draw-in groove 12 by regulation bolt 9, make excitation beam of vibration 3 fix with case side plate 1-1, install shock electric machine 2 on excitation beam of vibration 3.In order to ensure screen box 1 bulk strength, the feeding end 6 of described screen box 1 and exhaust end 8 are equipped with buttress brace 4, and buttress brace 4 two ends are fixed with case side plate 1-1 by clamping screw.
Screen box 1 bottom arranges two pack supports 5, and one of which support 5 is positioned at the feeding end 6 of screen box 1, and another pack support 5 is positioned at the exhaust end 8 of screen box 1.Support 5 is provided with support height adjustment structure, is provided with support span governor motion between two adjacent groups support 5.Described support height adjustment structure includes on support regulating block 13 under regulating block 14 and support, under support, on regulating block 13 end face and support, regulating block 14 bottom surface is equipped with vertical screwed hole, support 5 is provided with the external screw thread matched with vertical screwed hole, and support about 5 two ends screw in vertical screwed hole.Described support span governor motion includes adjusting screw rod 10, and under support, regulating block 13 side is provided with the lateral threaded holes matched with adjusting screw rod 10, and adjusting screw rod 10 two ends screw in lateral threaded holes.By swinging mounting 5, by rotating adjusting screw rod 10, the spacing of two pack supports 5 can be regulated with support 5 oneself height.In order to improve the self stability of screen box 1, between described screen box 1 and support 5, it is provided with shock-absorbing spring 15.
During vibrosieve work, screen box 1 vibrates under the drive of shock electric machine 2, and material is fed coarse-grained material after compass screen surface 7 sieve classification by feeding end 6 and discharges through exhaust end 8, and fine enters under sieve through compass screen surface 7, becomes fine particle product.The shock electric machine 2 being fixed on excitation beam of vibration 3 is the key that material bores gap layering, can be as desired to regulation eccentric block angle inside the shock electric machine 2 of feeding end 6 and exhaust end 8 realizes the size variation of exciting force.Excitation beam of vibration 3 steps up to be fixed on sieve box side plate 1-1 by regulation bolt 9.Slidable adjustment bolt 9 in horizontal draw-in groove 11, makes the span between two shock electric machines 2 realize change within the specific limits.Slip clamp stud in vertical draw-in groove 12, it is achieved two shock electric machines height change in vertical direction, and then make exciting force with screen box 1 barycenter relative to change in location, meet the requirement of uneven exciting force.Compass screen surface 7 usually requires that certain angle between horizontal plane, is regulated the height of two pack supports 5 respectively by the support height adjustment structure on the support 5 of feeding end and discharge end, it is achieved different inclination angles.During regulation compass screen surface 7 inclination angle, need to adjust support span governor motion simultaneously, make two pack supports 5 reach static equilibrium.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
