Description
Technical field
The present invention relates to a kind of disintegrating machine of comminuting matter mechanical field, is a kind of impact breaker specifically.
Background technology
The raw material fragmentation of industrial circles such as impact breaker is widely used in that metallurgy, mine, building materials, road are built, chemical industry and cement.As shown in Figure 4, it mainly partly is made up of housing, rotor block, first counterpunch board, second counterpunch board and the grain size regulating plate etc.It utilizes the beater plate of high speed rotary to come the broken material piece, becomes the finished product materials granularity after the fragmentation of material through crusher chamber and expansion chamber and discharges disintegrating machine.As everyone knows, impact breaker is the broken passage of a path, all engagement positions can only be controlled and the rotor block radial distance, and axially be one with the disintegrating machine cavity with wide crushed zone, the material that the architectural characteristic of impact breaker not only causes its discharging-material size that can not control material fully promptly not meet the discharging-material size size also may be discharged disintegrating machine, and the material of discharging can have very big kinetic energy, and disintegrating machine body, foundation of civil work and belt conveyor are caused serious damage.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, provide a kind of and can improve crushing efficiency, reduce the impact breaker of material disintegrating machine body, foundation of civil work impact damage.
The present invention realizes that the technical scheme of above-mentioned purpose is: impact breaker comprises the expansion chamber that rotor block, the grain size regulating plate and rotor block and the grain size regulating plate constitute; It is characterized in that: on expansion chamber discharging opening material is dished out the direction line, be provided with the impact baffle plate device.The setting of impact baffle plate device can effectively reduce material to disintegrating machine body, foundation of civil work impact damage, and simultaneously, material impacting impact baffle plate device can produce crushing effect once more.
Described impact baffle plate device comprises grillage, tooth plate; Tooth plate is arranged on the grillage, the tooth plate face of tooth plate and the expansion chamber discharging opening material angle that the direction line keep to be set of dishing out; For crushing efficiency that improves this device and the kinetic energy that at utmost reduces material, this set angle optimal selection is 90 °.
The top/bottom latitude that described tooth plate blocks is expansion chamber discharging opening material direction line each the 30 ° of formed sector region up and down of dishing out.This zone is the discharge zone (zone that material is dished out) of material, and most material can collide and impact retaining device.
Described impact baffle plate device is provided with the structure of barb in the bottom of grillage, the oblique angle groove that is mated also is set in the tooth plate bottom, and L type briquetting compresses tooth plate and is anchored on the grillage with bolt adjutant L type briquetting, and tooth plate can be by wedge extremely on grillage.Like this, the tooth plate dismounting and change of rapid wear is very convenient.
Another technical scheme that realizes above-mentioned purpose is: the impact baffle plate device also can be designed as monoblock type, and grillage and tooth plate are made the weldment or the foundry goods of an integral body, and briquetting and connector just can save.
Beneficial effect of the present invention is:
Impact breaker of the present invention, the setting of impact baffle plate device can effectively avoid material to the impact of disintegrating machine body, foundation of civil work and cause the generation of damage accident.Simultaneously can improve crusher in crushing efficient, effectively reduce discharging-material size and improve the material product qualified rate.Characteristics such as that this impact baffle plate device has is simple in structure, installation and maintenance convenient and safe and reliable to operation.

The specific embodiment
For this programme is better understood, with reference to the accompanying drawings the present invention is further detailed.
Embodiment 1: as shown in Figure 1, impact breaker comprises the expansion chamber 4 that rotor block 1, the grain size regulating plate 3 and rotor block and the grain size regulating plate constitute; On dishing out direction line 5, expansion chamber discharging opening material is provided with impact baffle plate device 2.
As shown in Figure 2, the impact baffle plate device is made up of grillage 6, tooth plate 7, L type briquetting 8.Grillage 6 is the steel frame construction of a welding, and design has two hinged axis holes 10 at the back, can use connecting axle that grillage 6 and disintegrating machine lower body are fixed up.Designed the structure of a barb in the bottom of grillage 6, also be provided with an oblique angle groove that is mated use in tooth plate 7 bottoms, use L type briquetting 8 that tooth plate 7 is compressed, and with bolt pair 9 L type briquetting 8 is anchored on the grillage 6, tooth plate 7 can be by wedge extremely on grillage 6.In order farthest to improve the crushing efficiency of tooth plate, the working surface of tooth plate 7 is designed to the shape of sawtooth.The impact baffle plate device is installed on the disintegrating machine body, and downstream at disintegrating machine discharge gate (whole chamber discharging opening), think roughly on the rotor block cylindrical that tangential direction from whole chamber discharging opening closest approach is the theoretical discharge direction (be expansion chamber discharging opening material dish out direction line direction) of material, with this point of contact is the downstream area that the zone of initial point and tangent line ± 30 ° is the disintegrating machine discharging opening, and the impact baffle plate device should block this zone comprehensively.From at utmost utilizing material kinetic energy and the most effective minimizing material kinetic energy to the purpose of the impact of disintegrating machine body, foundation of civil work (be subject to impact damaged zone as the mark Fig. 1 11), the working surface of this device should with vertical installation of theoretical discharge direction.
Can realize the another kind of example of the object of the invention: as shown in Figure 3, as a whole casting of impact baffle plate device or Welding Structure are designed to one with tooth plate and grillage, therefore can save briquetting and section connecting element.Its installation site should be identical with last example.
In addition to the implementation, patent of the present invention can also have other embodiment.Those skilled in the art should be realized that above embodiment only illustrates the present invention, and is not limitation of the invention.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of patent requirement of the present invention.
