Abstract
The utility model provides a split type crushing hammer on a shale crushing machine. The split type crushing hammer on the shale crushing machine comprises an impacting hammer head and a hammer arm which are fixedly connected through bolts and nuts; the nuts are connected with the bolts through stopping gaskets; the hammer arm is provided with an octagonal platform at the part on which each nut is arranged; and the stopping gaskets are conveniently fixed through the octagonal platform. According to the split type crushing hammer on a shale crushing machine provided by the utility model, the octagonal platform convenient for installing the stopping gaskets is arranged on the hammer arm, therefore, both the problem that a bolt-nut connecting pair is to be prevented from loosing under impacting and vibrating condition and the problem that the bolts cannot be revolved on related axis during being locked or working or disassembling can be solved, and moreover, the shortcoming that stress concentration easily occurred at the closed angle of a rectangular pyramid platform of a casting manufactured via wearable and fragile material can be avoided.
Description
Technical field
The utility model relates to the split type pulverizing hammer on a kind of shale pulverizer.
Background technology
Along with integrating lightweight, high-strength, energy-conservation, solved materials for wall production and use in the propelling of Green High Performance novel wall material of resource, the energy, harmonious development problem, the utilization day of the pulverizing hammer on the shale pulverizer is with extensively.Pulverizing on shale pulverizer hammer has monoblock type and split type two kinds, and split type pulverizing hammer can be saved the wear resisting steel iron material resource effectively.Split type pulverizing hammer on the shale pulverizer is to adopt bearing pin to connect mostly at present, bearing pin connects the gap that can not effectively eliminate hammerhead jib and hit tup on the one hand, hit on the other hand tup and belong to tower structure, the fragility cause owing to wear-resistant cast iron material under impact force action is very easily crashed through broken; Also have and adopt circular cone or rectangular pyramid conical surface bolt to connect, but these connect and not to solve bolt and nut and connect secondary easily loosening and make the problem of hitting the tup fragmentation under the impact shock operating mode, although rotation can not occur in rectangular pyramid conical surface bolt-locking or work or the dismounting, wear-resisting fragile material foundry goods tetragonous cone table sharp corner easily produces stress and concentrates and make the fragmentation in impact work of strike tup.
The utility model content
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of effectively eliminate hammerhead jib and the gap of hitting tup, wearability strong, prevent that the split type pulverizing that bolt and nut connects on the secondary shale pulverizer that becomes flexible, prevents to occur in bolt-locking or work or the dismounting rotation under the impact shock operating mode from hammering into shape.
Split type pulverizing hammer on a kind of shale pulverizer, comprise and hit tup and hammerhead jib, described strike tup and described hammerhead jib are connected and fixed by screw bolt and nut, described nut is connected with described bolt by stop washer, and described hammerhead jib is provided with eight terrace with edges of convenient fixing described stop washer at the described nut of installation position.
In the utility model, the end of described bolt is that homalocephalus is conical, the end of described bolt is installed in the draw-in groove that described strike tup and described bolt homalocephalus conical end shape be complementary, and the other end of described bolt passes described hammerhead jib upper bolt hole and is fixed on the described hammerhead jib by nut.
Adopt such scheme, utilization hammerhead jib be convenient to eight terrace with edges that stop washer installs not only solved bolt and nut connect secondary under the impact shock operating mode anti-loosening problem but also solved bolt-locking or work or dismounting in the problem of rotation does not appear, and avoided wear-resisting fragile material foundry goods tetragonous cone table sharp corner easily to produce the defective that stress is concentrated.

The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the split type pulverizing hammer on a kind of shale pulverizer in detail.
As shown in Figures 1 to 3, split type pulverizing hammer on the shale pulverizer, comprise and hit tup 2 and hammerhead jib 1, main shaft is flexibly connected on described hammerhead jib 1 and the pulverizer, described strike tup 2 be connected hammerhead jib 1 and connect by main shaft power transmission rotation work on the pulverizer by bolt 3, the end of described bolt 3 is that homalocephalus is conical, the end of described bolt 3 is installed in the draw-in groove that described strike tup 2 and described bolt 3 homalocephalus conical end shapes are complementary, the other end of described bolt 3 passes described hammerhead jib 1 upper bolt hole and is fixed on the described hammerhead jib 1 by nut 4, described nut 4 is connected with described bolt 3 by stop washer 5, and described hammerhead jib 1 is provided with eight terrace with edges 6 of convenient fixing described stop washer 5 at the described nut of installation 4 positions.
Claims (2)
1. the split type pulverizing hammer on the shale pulverizer, comprise and hit tup and hammerhead jib, described strike tup and described hammerhead jib are connected and fixed by screw bolt and nut, described nut is connected with described bolt by stop washer, it is characterized in that: described hammerhead jib is provided with eight terrace with edges of convenient fixing described stop washer at the described nut of installation position.
2. the split type pulverizing on the shale pulverizer according to claim 1 is hammered into shape, it is characterized in that: the end of described bolt is that homalocephalus is conical, the end of described bolt is installed in the draw-in groove that described strike tup and described bolt homalocephalus conical end shape be complementary, and the other end of described bolt passes described hammerhead jib upper bolt hole and is fixed on the described hammerhead jib by nut.
