Outer spokes 3 are connected by both ends locking nut 14 with main shaft 4；
Outer spokes 3 are connected by bolt with spacer sleeve 7；
Hammer leaf guide rod 2 is provided in the interior spoke mounting hole and outer spokes mounting hole；
The hammer leaf guide rod 2 is connected with hammer leaf 1；
1 tip inside of hammer leaf is provided with connecting hole；
The hammer leaf 1 is connected by connecting hole with hammer leaf guide rod 2；The hammer leaf 1 is sleeved on 2 outer circumference surface of hammer leaf guide rod
On；
The interior spoke location hole and outer spokes positioning hole are provided with limited block bar 6；
Limited block 5 is sleeved on limited block bar 6 by limited block pole perforating hole；
6 both ends of limited block bar are welded in outer spokes 3；
The outside of limited block 5 and main-shaft axis vertical direction are provided with limited block locating slot 13；
Hammer leaf guide rod and main-shaft axis vertical direction are provided with hammer leaf guide rod locating slot 15；
The position corresponding with limited block locating slot 13 of hammer leaf guide rod 2 is provided with hammer leaf guide rod locating slot 15；
The top of positioning pin 16 is arranged in hammer leaf guide rod locating slot 15；
The lower part of positioning pin 16 is arranged in limited block locating slot 13；
Hammer leaf guide rod 2 is connected by positioning pin 16 with limited block 5；
Hammer leaf guide rod 2 is positioned by positioning pin 16 in axis direction.
Limited block locating slot 13 is arc groove, and limited block locating slot cross section is arc-shaped；
Hammer leaf guide rod locating slot 15 is arc groove, and hammer leaf guide rod locating slot cross section is arc-shaped.
The positioning pin 16 is split pin.
Hammer leaf guide rod locating slot is arranged in the middle part of hammer leaf guide rod axis.
Hammer leaf 1 is uniformly arranged along axis.
There are four limited blocks for setting on the same cross section of main shaft；Limited block is radially symmetrical arranged along main shaft；Limited block
It is uniformly arranged along main shaft circumferencial direction；Limited block includes upper limit position block 51, lower position block 52, left limit block and right limit block；On
Limited block is identical with the position of the limiting slot 17 of lower position block；Left limit block is identical with the position of the limiting slot of right limit block；On
The limiting slot of limited block and lower position block and the position of left limit block and the limiting slot of right limit block are staggered in axis direction；
Hammer leaf inner end is arranged in limiting slot.It is more preferable to the crushing effect of material.It is equivalent to and reduces hammer leaf and hammer leaf on axis
Distance；Arrangement more crypto set of the hammer leaf in axis direction.
The utility model feed grinder rotor high rigidity hammer leaf bar position limiting structure, hammer leaf guide rod can neither circumferencial direction
Rotation can not move axially；Simplifying structure simultaneously keeps operation simpler time saving；Customer using cost is reduced, is had high
Use value；Equipment failure rate is reduced, is improved work efficiency, the service life of feed grinder is extended.
Interior spoke 8, outer spokes 3, spacer sleeve 7 are sleeved on main shaft 4, are realized each spoke axially spaced-apart by spacer sleeve and are determined
Position, then it is fastened on both ends locknut the appropriate location of axis；With common between the spacer sleeve and axis and interior spoke at axis and both ends
Flat key 9 connects；Limited block is fixed on each spoke by limited block bar, and limited block bar both ends are welded in outer spokes,
Limited block is thoroughly fixed on rotor in this way.
Structure is complicated for existing hammer leaf bar axially stop block, processing difficulties, due to abrasion, causes hammer leaf bar axial
Limit is difficult to realize.
The corresponding site of bar is processed to the arc-shaped locating slot vertical with its axis of corresponding size.
The corresponding site of middle part limited block cast out or process corresponding size, shape locating slot.
The limited block for being provided with arc-shaped locating slot arranges 1-2 block in each hammer leaf bar length direction.
Limiting slot on limited block is more reasonable in order to obtain hammer leaf in axis direction and circumferential directions.
Split pin is inserted into groove after rotor overall package and the open end of split pin is rived, is bent.
This split pin is equivalent to the round key perpendicular to bar axis direction, and bar and limited block C is relatively fixed, by
It either works or stops working all very littles of axial force suffered by its bar in pulverizer, so bar can neither circumference side at this time
It can not be moved axially to rotation, by bar defined position.
Working principle:
1, during wearing hammer leaf, bar, which is struck, to be gradually moved to the left, and after hammer leaf has been worn, bar in place, and is arrived
Its groove direction is adjusted before position, then split pin is inserted into groove and the open end of split pin is rived, is bent.It wears at this time
Bar can neither circumferencial direction rotation can not move axially, by bar defined position.
If 2, bar in long-term use a direction by long-term motion hammer leaf abrasion there is circumferencial direction trace (trace
Mark length accounts for about a quarter of whole circumference) and the hammer leaf of pulverizer may hit sieve when trace reaches certain depth
It is bad, only bar diametrical direction need to be rotated 180 degree at this time.
With the corresponding arc-shaped groove of angular grinding machining, that is, reusable (because of the small-sized institute of arc-shaped trench cross section
Not influence its intensity)；Hammer leaf and bar contact position are smooth, cylindrical peripheral surfaces at this time.
Existing rotor some limits the structure of bar axial movement with two split pins, because high rigidity bar
Hardness is too high so the very difficult and cost that drills is too high.
Existing rotor some fixes the structure of bar in outer spokes outer end bolt, baffle, because this structure is in powder
Bolt, baffle are easy to be worn and lose its function when broken light material.
