Abstract

The utility model discloses a horizontal double-shaft high-efficiency vibrating screen comprising four bearing cavities arranged on a screen box, a main drive eccentric shaft and a driven eccentric shaft arranged at central positions of the four bearing cavities; wherein eccentricities of the two eccentric shafts are consistent; two ends of the main drive eccentric shaft are respectively provided with a drive gear and an idle gear, two ends of the driven eccentric shaft are respectively provided with a driven gear and an idle gear; the drive gear, the driven gear and the idle gears are all provided with screwed holes and locating pinholes used for installing eccentric blocks, the numbers of the two sets of eccentric blocks can be consistent or inconsistent according to needs; the eccentric blocks are respectively fixed on the drive gear, the driven gear and the idle gears through screws and locating pins; the screen box is supported on springs; and a drive component drives a main shaft wheel to rotate through a V-belt, then a vibration exciter works to realize vibration of equipment.

Description

Horizontal twin shaft high-efficiency vibration sieve

Technical field

The utility model relates to a kind of horizontal twin shaft high-efficiency vibration sieve, especially can convert the screening operation that the horizontal ellipse vibratory sieve is applicable to various materials into; Also can also be adjusted into simultaneously operations such as dehydration that straight line shaker is applicable to various materials, desliming.

Background technology

Employed three axle horizontal elliptically vibrating screens are on the basis of comprehensive circular shale shaker and linear vibrating screen at present, a kind of reasonable vibratory sieve that grows up, but its complex structure adjustment is loaded down with trivial details, occurs mistake easily, and maintenance difficulties is big.Reduced operating efficiency.

Summary of the invention

The purpose of the utility model is directed against the deficiency of above-mentioned prior art and a kind of horizontal twin shaft high-efficiency vibration sieve is provided.

For realizing above-mentioned purpose, the utility model can be taked following technical proposals:

The described horizontal twin shaft high-efficiency vibration sieve of the utility model, it comprises four bearing cavitys that are positioned on the screen box, and is positioned at a transmission eccentric shaft and a driven eccentric shaft of four bearing cavity middle positions; The offset homogeneous of two eccentric shafts extremely; Two ends at the transmission eccentric shaft are equipped with travelling gear and idle pulley respectively, at the two ends of driven eccentric shaft driven gear and idle pulley are housed respectively, on travelling gear, driven gear gear and idle pulley, all are processed with the screwed hole and the dowel hole of setting-up eccentricity piece; The quantity of two groups of eccentric blocks as required can be consistent or inconsistent; Eccentric block is separately fixed on travelling gear, driven gear and the idle pulley through screw and alignment pin, and screen box is bearing on the spring, is rotated through V-belt driving main shaft wheel by drive disk assembly; Vibrator work realizes the vibration of equipment.

Described adjustment eccentric block is on travelling gear, driven gear and the idle pulley.

Described trunnion axis has two: transmission eccentric shaft and driven eccentric shaft.

The positive progressive effect of the utility model is; The utility model high-efficiency vibration sieves the simple and reasonable of vibrator; In conjunction with eccentric shaft and the eccentric two-fold advantage of piece, make the bigger more effective vibrator of vibrator, improved the disposal ability and the screening efficiency of sieve; Can adjust simultaneously eccentric block and make horizontal linear sieve and horizontal ellipse sieve on this machine, realize conversion, realize the multiple use of sieve.

The specific embodiment

Like Fig. 3 and shown in Figure 4; The described horizontal twin shaft high-efficiency vibration sieve of the utility model, it comprises four bearing cavitys 6 that are positioned on the screen box 1, and is positioned at a transmission eccentric shaft 5 and a driven eccentric shaft 12 of four bearing cavity 6 middle positions; The offset homogeneous of two eccentric shafts extremely; Travelling gear 10 and idle pulley 4 are housed respectively at the two ends of transmission eccentric shaft 5, driven gear 11 and idle pulley 4 are housed respectively at the two ends of driven eccentric shaft 12, all be processed with the screwed hole and the dowel hole of setting-up eccentricity piece 9 on travelling gear 10, driven gear 11 and the idle pulley 4; The quantity of two groups of eccentric blocks 9 as required can be consistent or inconsistent; Eccentric block is separately fixed on travelling gear 10, driven gear 11 and the idle pulley 4 through screw 8 and alignment pin, and screen box 1 is bearing on the spring, is rotated through V-belt driving main shaft wheel 3 by drive disk assembly 2; Vibrator work realizes the vibration of equipment.

Described adjustment eccentric block 9 is travelling gears 10 on, moving gear 11 and idle pulley 4.

Described trunnion axis has two: transmission eccentric shaft 5 and driven eccentric shaft 12.

As shown in Figure 5; Two independent movement locus of eccentric shaft are round, because the eccentric block that two eccentric shafts are joined is different, its synthetic movement locus is oval; The gears engaged starting phase angle of two eccentric shaft end of adjustment; Can adjust the vibrating direction angle (major axis of movement locus and the angle of horizontal direction) of sieve easily, illustrated deflection is 45 °, and this is that utility model horizontal vibration sieve is an oval sieve; If just the same the eccentric block that two eccentric shafts are joined, its synthetic movement locus will be a straight line, and this is that to remain the gears engaged of two eccentric shaft end of adjustment initial.

Claims

1. a horizontal twin shaft high-efficiency vibration sieves; It comprises four bearing cavitys that are positioned on the screen box; And being positioned at a transmission eccentric shaft and a driven eccentric shaft of four bearing cavity middle positions, the offset of two eccentric shafts is all consistent, at the two ends of transmission eccentric shaft travelling gear and idle pulley is housed respectively; Two ends at driven eccentric shaft are equipped with driven gear and idle pulley respectively; It is characterized in that: all be processed with the screwed hole and the dowel hole of setting-up eccentricity piece on travelling gear, driven gear and the idle pulley, the quantity of two groups of eccentric blocks is adjusted as required, and eccentric block is separately fixed on travelling gear, driven gear and the idle pulley through screw and alignment pin.
