The invention discloses an amplitude-adjustable bridge-type vibrating sieve device, which belongs to a vibrating sieve device serving as mining equipment. The vibrating sieve device has a bridge type frame consisting of an upper longitudinal beam, upper cross beams, pull rods, a lower longitudinal beam, and lower cross beams, wherein the lower cross beams are provided with screen nuts and fastened rubber sleeves, screen pieces are sequentially spread on the rubber sleeves according to an ascending order of the specifications of holes; two sides inside the frame are fixedly connected with baffle plates; bearings are fixedly connected with the inside of bearing bushings; the bearing bushings are arranged in and fixedly connected with the inside of bearing outer bushings; two ends of each shaft barrel are inserted into and fixedly connected with the centre bores of the bearing outer bushings; eccentric shafts are arranged in the in the shaft barrels; the parts, close to the two ends, of each eccentric shaft are arranged in the inner holes of the bearings; the upper and lower beams between the bridge type frame are fixedly connected together by the bearing outer housings, upper connecting plates and connecting plates; and two ends of each eccentric shaft are fixedly connected with belt wheels and counterweights. Compared with the products of the same class, the vibrating sieve device saves maintenance labor cost and improves the working efficiency by 15 to 25 percent.
Description
1. Technical field: [0001] The adjustable amplitude bridge type vibrating screen device belongs to the vibrating screen device in mining equipment. 2. Background technology: [0002] It is known that the vibration amplitude of the vibrating screen currently used in mining equipment is adjusted through the increase or decrease of the number of counterweight irons to adjust the amplitude of the vibrating screen. Since the determination of the increase and decrease in the number of counterweight irons is done through It is determined by repeated exchanges and vibration experiments, which increases operational difficulties in adjusting the amplitude of the vibrating screen. Reduce the output of finished goods. At present, the vibrating screens used in mines are multi-layer vibrating screens. During maintenance, disassembly and assembly are complicated, which increases maintenance time, affects the working efficiency of vibrating screens, and wastes labor costs. 3. Contents of...
