Abstract

The utility model belongs to a material crushing and screening device, which comprises a machine frame, a crushing roller, a transmission shaft, and a crushing chamber; the vibration roller type screen crusher is characterized in that the transmission shaft connecting with a vibration exciter is connected with a concentric crushing roller through a bearing, the crushing roller and the transmission shaft can be freely rotated, and the crushing roller, inner concave engaging plates fixed with both sides of the crushing roller and an inner concave camber screen plate on the lower part of the crushing roller form a crushing chamber. The structure design of the vibration roller type screen crusher can be used for improving the crushing efficiency and prolonging the service life of the crushing roller, and the down time of the vibration roller type screen crusher can be reduced; the vibration roller type screen crusher can use the crushing principle to accelerate the material crushing efficiency and the material screening.

Description

Vibration roller type screen crusher

The utility model belongs to the material crushing and screening equipment, mainly proposes a kind of vibration roll-type screening crusher.

The revolution kibbler roll of prior art is mainly by frame, breaker roll, eccentric shaft, fixedly concave surface is nibbled compositions such as plate, the eccentric part and the breaker roll of eccentric shaft are concentric, therefore also there is an offset in the centre of gyration of breaker roll and eccentric shaft, fixedly inner concave nibble plate and frame connects firmly, fixedly inner concave nibbles that plate and breaker roll are common forms a crusher chamber, when eccentric shaft turns round, make breaker roll make turning motion in certain limit, generation is to the crushing force of material, the material of coming in by top breaker roll and fixedly indent nibble in the crusher chamber that plate forms and be broken, then by breaker roll and fixedly indent nibble the underclearance that plate forms and discharge; In use because there is inhomogeneities (it is big, middle tiny to be generally two) in the wearing and tearing of roller, cause roller after use a period of time, marker size is demarcated granularity considerably beyond it, has to change consumable accessory too early and satisfies production requirement.

The purpose of this utility model promptly is this, proposes a kind of vibration roll-type screening crusher, improves crushing effect and prolongs service life of breaker roll, thereby solve the problem that above-mentioned prior art exists.

The technical scheme that the utility model is taked is: the power transmission shaft that is connected with vibrator connects a concentric breaker roll by bearing, rotate freely between breaker roll and the power transmission shaft, the inner sunken face sieve plate that the fixedly indent of breaker roll and its both sides is nibbled plate and its underpart constitutes crusher chamber jointly, breaker roll links to each other with frame by bearing and flexible member, and fixedly indent is nibbled plate and inner sunken face sieve plate and frame and connected firmly.

The utility model is provided with the indent fixed screen deck in the breaker roll bottom, the size of marker size is only relevant with the size of screen size, the particle that does not reach release mesh can't be discharged in crusher chamber, so breaker roll is as not wearing and tearing fully, can not influence marker size, do not need to change too early breaker roll, the increase breaker roll life-span can reach 3～5 times, has significantly reduced downtime; Utilize the swing crushing principle, can accelerate the crushing efficiency and the screening of material.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is Figure 1A-A profile.

Shown in accompanying

drawing

1,2, breaker roll 3 and do not have eccentric power transmission shaft 2 arranged concentric, both link by bearing 9, can turn round relatively between the two, breaker roll 3 links with frame 1 by bearing 8 and flexible member 7, frame 1 and fixedly indent is nibbled plate 5, inner sunken face sieve plate 4 connects firmly, breaker roll 3 has the crusher chamber B that progressively dwindles from top to bottom and can control marker size with inner sunken face sieve plate 4 one of the common formation that the fixedly indent of its both sides is nibbled plate 5 and bottom, and power transmission shaft 2 two ends and vibrator 6 connect firmly.

Inner sunken face sieve plate 4 is nibbled plate 5 with indent and be can be an overall structure, and also can nibble plate 5 and form integrative-structure by inner sunken face sieve plate 4 two ends connection indent,

The utility model operation principle: vibrator 6 work that motor drives power transmission shaft 2 by transmission device and connects firmly with it, produce unbalanced exciting force, drive breaker roll 3 and produce the periodic change in location of nibbling plate 5 and inner sunken face sieve plate 4 with respect to fixing indent, material in the crusher chamber 8 is dashed, hit, compression, the periodicity active force of roll extrusion, material is progressively weakened, after being broken, material discharges by the sieve aperture on the inner sunken face sieve plate 4, the size of adjusting sieve aperture can be selected the granule size that requires arbitrarily, and it doesn't matter with the shape of breaker roll and wear extent size.

Claims

1, a kind of vibration roll-type screening crusher includes frame (1), breaker roll (3), power transmission shaft and crusher chamber; Feature of the present utility model is that the power transmission shaft (2) that is connected with vibrator (6) connects a concentric breaker roll (3) by bearing (8), can rotate freely between breaker roll (3) and the power transmission shaft (2), breaker roll (3) both sides for fixing indent nibble plate (5), bottom be inner sunken face sieve plate (4) and with they common formation crusher chamber.

2,, it is characterized in that indent is nibbled plate (5) and inner sunken face sieve plate (4) can be an overall structure according to the described vibration roll-type of claim 1 screening crusher.

3,, it is characterized in that inner sunken face sieve plate (4) two ends connect indent and nibble plate (5) formation integrative-structure according to the described vibration roll-type of claim 1 screening crusher.
