Type of the present invention comprises: the moving jaw liner plate of jaw crusher and decide the jaw liner plate, its structural feature are the middle and upper part of every block of liner plate to be originally that the liner plate of triangle bar shaped tooth is cast become independently conical one by one profile of tooth.When moving jaw liner plate when deciding that the jaw liner plate is relative to be meshed, these circular cone teeth will have indenting shape.The circular cone tooth of just persuading the jaw liner plate and decide the jaw liner plate mutually correspondence the opposite groove.The middle and lower part of liner plate does not change original bar shaped odontoid.That is to say that the conical tooth that utilizes the liner plate middle and upper part helps broken bulk stone, reduce the drag of bulk stone eccentric shaft.Utilize the middle and lower part bar shaped tooth of liner plate be beneficial in the processing fragmentation of finger stone.

The advantage of this invention type is: owing to adopted the profile of tooth of cone shape in the middle and upper part of liner plate, make jaw crusher when work, the lifting surface area when having reduced the extruding stone.So both increased the pressure of liner plate circular cone tooth, and can reduce the drag of stone greatly again, and so just can reduce the generation of drag to greatest extent eccentric shaft and bearing and the various structural damage power of jaw crusher to liner plate to stone.For safety in production, carry out production strictly in line with rules and regulations, created condition.Can be the life cycle of prolongation equipment,, provide reliable assurance for improving the productivity effect of enterprise.Because the enterprises that great majority utilize jaw crusher are when utilizing this equipment, the overwhelming majority all interrelates with the whole production streamline, in case this equipment generation mechanical breakdown, the neck that must cause whole piece production line card, and have to stop production.The performance of utilizing this technology to change thus and improving jaw crusher has very significant meaning.

Be described in further detail below in conjunction with the specific embodiment of accompanying drawing type of the present invention:

Fig. 1 is one of type coupling part structure chart of the present invention;

Fig. 2 is along the B-B cutaway view among Fig. 1;

Fig. 3 is along the A-A cutaway view among Fig. 1;

Fig. 4 is along the F-F cutaway view among Fig. 1;

Fig. 5 is two of type coupling part structure chart of the present invention;

Fig. 6 is along the D-D cutaway view among Fig. 5;

Fig. 7 is along the C-C cutaway view among Fig. 5;

Fig. 8 is the view of taking along Fig. 5.

Among the figure 1, liner plate 2, circular cone tooth 3, bar shaped tooth 4, triangular groove 5, groove 6, inclination angle 7, circular cone tooth angle degree 8, inclination angles 9, bar shaped tooth section angle

Be and liner plate (1) profile of tooth of cone shape independently one by one cast in block that the height of each circular cone tooth (2) is all consistent with the height of the bar shaped tooth (3) of same block of liner plate (1) middle and lower part as Fig. 1, Fig. 2, Fig. 3, circular cone tooth shown in Figure 4 (2).Want equidistant branch between every row's circular cone tooth (2), the spacing between every row's circular cone tooth (2) all with bar shaped tooth (3) between distance consistent.Every row's bar shaped tooth (3) above every row's circular cone tooth (2) and the liner plate (1) is all on same straight line.The bottom surface diameter of each circular cone tooth (2) can be wide consistent with the bottom surface of bar shaped tooth (3).After the lip-deep bar shaped tooth in the liner plate middle and upper part original jaw crusher (3) is changed into the shape of circular cone tooth (2), can be when not influencing this machine production efficiency, also can make the working environment of this machine obtain the improvement of a matter.Because every block of moving jaw liner plate (1) and the tooth of circular cone tooth (2) of deciding the middle and upper part on jaw liner plate (1) surface are separate components one by one, when circular cone tooth (2) is worked, because the contact area the when contact area the during extruding of circular cone tooth (2) and stone is significantly smaller than bar shaped tooth (3) with the stone extruding, thus circular cone tooth (2) to the pressure of stone just from far away greater than the pressure of bar shaped tooth (3) to stone.So just can make the suffered drag of eccentric shaft on the jaw crusher be subtracted greatly.The power that jaw crusher is born when work is better distributed, anatomize as can be seen, the place that jaw crusher is the most stressed, still in the position, middle and upper part of liner plate, reason is that stone is big, quantity is many, very near again apart from eccentric shaft, corresponding lever force is just little, and the suffered drag of eccentric shaft must be big, so the chance that causes each one of jaw crusher to damage is just inevitable many, after liner plate is changed into the circular cone tooth.Liner plate (1) middle and upper part circular cone tooth (2) can only stung bulk stone, the stone of middle fritter can't be stung, so just can make the stressed degree at liner plate (1) each position, upper, middle and lower obtain the rational and effective distribution, both stones of the broken bulk in the top of liner plate (1), the broken medium size stone in middle part, the broken again fritter stone in bottom.

During jaw crusher work, moving jaw liner plate (1) and decide each circular cone tooth (2) above the liner plate of jaw liner plate (1) middle and upper part corresponding mutually the groove (5) above the other side's liner plate, moving equally jaw liner plate (1) and decide triangle bar shaped tooth (3) above the liner plate of jaw liner plate (1) middle and lower part also be mutual correspondence the triangular groove (4) above the other side's liner plate.That utilizes that such liner plate can make the disintegrating machine liner plate whole stressedly obtains more rational distribution, from Fig. 5, Fig. 6, Fig. 7, Fig. 8 as can be known, the angle of inclination (8) at said inclination angle (6) can be selected within (30-60 degree), and the effect of inclination angle (6) is to concentrate for the stress that reduces foundry goods.The domatic angle (7) of said circular cone tooth (2) can be selected within (30-60 degree).Generally speaking can be consistent with the section angle of bar shaped tooth (3), the section angle (9) of said bar shaped tooth (3) can be selected between (60-120 degree), and the section angle (9) of the bar shaped tooth of liner plate is all about 90 degree generally speaking.Because the circular cone tooth (2) above the liner plate (1) and the material of bar shaped tooth (3) all are to make with the very strong potassium steel of solderability, use so can take the method for built-up welding to repair when circular cone tooth (2) and bar shaped tooth (3) may wear to a certain degree, the liner plate (1) that preferably in time more renews is more favourable to equipment certainly.

In sum as can be known, the liner plate (1) that the enforcement of this technology can make jaw crusher can make when work after the stressed degree at each position, upper, middle and lower of every block of liner plate (1) more becomes rationally to greatest extent, the utilization rate of jaw crusher is improved to greatest extent, the accident rate of equipment also can reduce accordingly greatly, and production efficiency must more effectively improve.
