Abstract
A kind of grinder hammerhead connecting pin, comprise shank, groove, plunger and snap ring, the two ends of shank are provided with plunger, between shank and plunger, be provided with groove.Described shank, plunger are cylindrical, and the cross-sectional diameter of shank is greater than the cross-sectional diameter of plunger, and the length of shank is greater than the length of plunger, and the width of described groove is less than the length of plunger.Described snap ring is the ring bodies with 1-2cm breach, and the width of its inner surface is less than the width of outer surface, consistent with the width of groove, and its cross section is wedge shape, can be stuck on groove tightly.The beneficial effects of the utility model are: structure is simple, easy to manufacture, low cost of manufacture, and installation, convenient disassembly, can prevent material to the wearing and tearing of self, extend the service life of grinder hammerhead, reduce the number of times changing tup.
Description
Technical field:
The utility model relates to a kind of grinder hammerhead connecting pin, is a vitals of grinder hammerhead.
Background technology:
Impact breaker is a kind of crushing mechanism utilizing impact energy to carry out broken material, material impact several times and broken between the tup and counterpunch board of high-speed rotation, percentage of damage is high, it can be done, wet two kinds of fragmentations, is applicable to the departments such as mine, cement, coal, metallurgy, building materials, highway, burning, carries out in small, broken bits to medium hardness and brittle material, adjustment castor interspace can be required according to user, changing discharging-material size, with satisfied different demand, is a kind of comparatively common tradition machinery.Impact crusher hammer head is a vitals of impact breaker, and the quality of its performance decides the height of the percentage of damage of disintegrating machine.The impact crusher hammer head of current use is with bolts, and bolt is easily subject to the wearing and tearing of material, makes the service life of impact crusher hammer head short, and the number of times changing tup is frequent, and impact is produced normally.
Summary of the invention:
The purpose of this utility model is to provide a kind of grinder hammerhead connecting pin, and this kind of grinder hammerhead connecting pin can prevent the wearing and tearing of material, extends the service life of grinder hammerhead.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of grinder hammerhead connecting pin, comprise shank, groove, plunger and snap ring, the two ends of shank are provided with plunger, between shank and plunger, be provided with groove.Described shank, plunger are cylindrical, and the cross-sectional diameter of shank is greater than the cross-sectional diameter of plunger, and the length degree of shank is greater than the length of plunger, and the width of described groove is less than the length of plunger.Described snap ring is the ring bodies with 1-2cm breach, and the width of its inner surface is less than the width of outer surface, consistent with the width of groove, and its cross section is wedge shape, can be stuck on groove tightly.
The beneficial effects of the utility model are: structure is simple, easy to manufacture, low cost of manufacture, and installation, convenient disassembly, can prevent material to the wearing and tearing of self, extend the service life of grinder hammerhead, reduce the number of times changing tup.
Accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of snap ring in the utility model.
In figure: 1 shank, 2 grooves, 3 plungers, 4 snap rings.
