Abstract

The utility model relates to the improvement of the general-purpose double toggle jaw crusher in the prior art, which is characterized in that one end of a moving jaw body contacting with a knee plate is a back cut feed opening of a crushing chamber, and the hinge point between the moving jaw body and a crank shaft is an undercut discharge opening of the crushing chamber; a moving toothed plate of the moving jaw body corresponding to a pull rod is included at more than twelve DEG, the yield of the crusher can be increased, and abrasion and energy consumption of the crusher can be reduced. The included angle between moving and fixed toothed plates on the lower part of one fifth to one third of the crushing chamber degree is less than 4 DEG, and the inverted jaw crusher with the reciprocating member is provided with the functions of a roll grinder.

Description

Inverted jaw crusher with reciprocating member

The utility model relates to a kind of improved single toggle jaw crusher, is the machine of the various ores of a kind of fragmentation.

Present single toggle jaw crusher basic structure is crank and rocker mechanism, and varies in size by charging aperture and to make the specification that varies in size.Its basic structure is seen accompanying drawing 1, and operation principle is seen accompanying drawing 2.In this structure, motor drives main shaft (2) motion after slowing down by big belt pulley (1).Main shaft (2) is a bent axle, and main shaft and moving gnathosoma (3) are equivalent to crank (4) and the connecting rod (5) in the crank and rocker mechanism respectively.Reach top swing tooth plate (6) with respect to the next broken building stones of the motion of fixed tooth plate (7) by moving jaw (3) during work.Space between swing tooth plate (6) and fixed tooth plate (7) is up big and down small, puts into the building stones of bulk from top charging aperture (8) and discharges from discharge gate (9) at last through being broken several times.The movement locus of swing tooth plate (6) upper, middle and lower portion each any is seen accompanying drawing 2(10), (11), (12).In, the angle (14) of the direction of motion (13) and fixed tooth plate (7) normal for tooth surface is 67 ° during the material extrusion of lower point, upwards slides easily when causing building stones crushed, forms idle running.And often on the flank of tooth, produce very large frictional force.This situation had both increased friction power loss, had also aggravated the wearing and tearing of tooth plate in a large number.The obstruction that slide, idle running has caused broken material process has again greatly influenced machine production.Now broken motor-driven decided flank of tooth angle and is no more than 23 °.Because easier slip when building stones were broken when angle was big, so advance, the ratio of marker size is less relatively, adopts the two-stage fragmentation to obtain than small grain size now usually.

Find that when patent searching and document notification number is 89207347 for the 2052684(application number) patent building stones sliding problem when proposing bracket and solving the single toggle jaw crusher broken material for the negative method that supports.But because moving gnathosoma is subjected to a reaction force that makes progress when pressing material, moving gnathosoma again by main shaft with this to power, affact on the bearing cap of body.Bolt of bearing cap is difficult to bear this impulsive force for a long time, so this structure is difficult for realizing in actual applications.

The purpose of this utility model is that present complexity pendulum jaw crusher is transformed, and makes it improve output, cuts down the consumption of energy and weares and teares, and reduces to discharge material granularity.

The utility model is inverted the moving jaw in the present single toggle jaw crusher and is used, and like this can be reasonably the movement locus of moving tooth plate be used for brokenly the material process.

Below with reference to accompanying drawing structure working principle of the present utility model is elaborated.

Fig. 3 is the front view that the utility model is cut open from center line.

Fig. 4 is the vertical view of the utility model partial cutaway.

Fig. 5 is a fundamental diagram of the present utility model.

Mechanism of the present utility model when broken material, by connecting rod in the mechanism (5) and top moving tooth plate (6) with respect to the motion of fixed tooth plate (7) building stones of crushing.Building stones enter crusher chamber from the support of connecting rod (15) under gravity.Along with the building stones face that constantly is broken diminishes and descending gradually, discharge from connecting rod (5) and crank (4) hinge joint at last.In structure of the present utility model, the angle that the direction of motion of moving tooth plate and the moving tooth plate flank of tooth are found is 42 °, with the angle of the normal for tooth surface of deciding tooth plate be 15 °.Moving tooth plate in this mechanism on the moving gnathosoma has angle more than 12 ° for pull bar.The going up of (structure shown in the accompanying drawing is 25 °) crusher chamber, middle part two flank of tooth angles account for the crusher chamber degree of depth 1/5th to 1/3rd after (structure shown in the accompanying drawing is 32 °) more than 26 ° is through a changeover portion bottom, two flank of tooth angles are less than 5 °.The adjustment of discharge gate (9) is adjusted along moving up and down of tooth plate bottom surface by swing tooth plate (6) and fixed tooth plate (7) that different size thickness is installed.Moving tooth plate two-end thickness specification difference also can be adjusted discharge gate (9) by changing the head use.The side plate (18) (because side plate does not also work the tooth plate effect that is fixed except protection body left and right sides wall is not worn) of extracting the crusher chamber both sides when swing tooth plate is adjusted out increases or reduce backing plate group (17) both can be finished.

The utility model has following advantage than present single toggle jaw crusher:

1, the maximum angle of the direction of motion of swing tooth plate and two tooth plate plate face normals is reduced to 42 ° by 67 °.Eliminated the phenomenon that building stones skid when broken.Reduced choking phenomenon in the wearing and tearing of machine energy consumption tooth plate and the broken material process.The same model machine production can improve nearly one times.

2, swing tooth plate (6) and connecting rod (5) have the angle more than 12 °, make the horizontal throw upper, middle and lower portion of swing tooth plate on average increase by 60% when angle is 25 °.Make the descending amount of each reciprocal building stones of moving jaw of the present utility model increase by 54%.Output is obviously increased.

3, in the utility model moving when deciding flank of tooth angle and being 32 ° building stones can not slide yet.So account for the whole disintegrating machine chamber degree of depth 1/3rd to 1/5th (complying with different disintegrating machine specifications and difference) in the bottom of crusher chamber one section is moved and decides flank of tooth angle less than 5 °.Make this section have function in small, broken bits as discharge gate.Machine of the design can be equivalent to a primary breaker and the fine crusher in the present machine series.

Because the utility model structure is unlike present machine construction complexity, jaw crusher manufacturer all can produce now.

Claims

1, a kind of inversion type single toggle jaw crusher is characterized in that the end that gnathosoma is supported by elbow is that the charging of crusher chamber is suitable for reading when using crank and rocker mechanism, and the hinged end of gnathosoma and main shaft is the discharge end opening of crusher chamber.

2, it is characterized in that on the moving gnathosoma by the line in the middle of the bracket strong point and the moving gnathosoma main shaft and the angle that props up tooth plate above 12 ° at the described disintegrating machine of claim 1.

3, the angle of it is characterized in that on the crusher chamber at right 1 described disintegrating machine, the middle part is moving, deciding two tooth plates accounts for the bottom of the crusher chamber degree of depth 1/5th to 1/3rd above 26 °, and two flank of tooth angles are less than 5 °.
