The bottom of screening case 1 is connected through the boss rotation at pivot and base 12 top for screening case 1 can be for base 12 horizontal hunting. The coarse flask 6 and the fine flask 14 are fixedly mounted on the base 12, respectively.
As shown in fig. 1 and 2, the vibration generating device includes a mount 19, a motor 11, a transmission belt, a crankshaft 9, and a rolling bearing 8.
The mounting seat 19 is made of steel or iron casting and is mounted on the base 12 through a fixing bolt 20.
The motor 11 is mounted on a mounting seat 19, and the crankshaft 9 is mounted on the mounting seat 19 through two bearing seats 10. The bearing seat 10 is internally provided with a sliding bearing consisting of an upper bearing bush and a lower bearing bush. The motor 11 drives the crankshaft 9 to rotate through a transmission belt. The rolling bearing 8 is arranged on the eccentric part of the crankshaft 9, two sides of the rolling bearing are respectively provided with a shaft retainer ring for axial limiting, and the outer ring is contacted with the bottom of the screening box 1.
During operation, motor 11 passes through the drive belt and drives bent axle 9 and rotate, and antifriction bearing 8 does eccentric rotation, incessantly promotes screening case 1 and swings around the rotation junction of bottom to realize the vibration of whole screening case 1.
Further, as shown in fig. 2, a through groove which is through up and down is further formed in the mounting seat 19, and the direction of the through groove is perpendicular to the axis of the crankshaft 9; the mounting 19 is secured to the base 12 by fixing bolts 20 passing through the through slots. After loosening the fixing bolt 20, the entire vibration generating device can be moved. As shown in fig. 1, the reciprocating range of the rolling bearing 8 in the vertical direction is fixed, and as the distance between the rolling bearing and the rotary joint changes, the amplitude of the swing angle of the screening box 1 also changes, so that the adjustment of the vibration amplitude of the screening box 1 is realized.
The top of the screening box 1 is provided with more than two feeding ports 2 for adding tailings. The screening box 1 is internally provided with a first screening plate 3 and a second screening plate 18 from top to bottom in sequence. The first sieve plate 3 and the second sieve plate 18 are both V-shaped or conical. The lowest part of the first sieve plate 3 is provided with a first opening, the first opening is connected with a tubular first discharging channel 4, and the outer end of the first discharging channel 4 is communicated with the coarse sand box 6 through a first hose 5; the lowest part of the second sieve plate 18 is provided with a second opening, the second opening is connected with a second tubular discharge channel 17, and the outer end of the second discharge channel 17 is communicated with the fine sand box 14 through a second hose 16.
