The utility model also provides a kind of hammer mill that is provided with described hammer mill damping device, and described hammer mill damping device is bolted between described housing and described broken kerve.
The flexible member of hammer mill damping device of the present utility model has the effect of buffering, absorbing; reduce the vibration transmission between broken kerve and housing; motor in effective protection hammer mill and hydraulic system etc.; prevent from making to connect because of huge vibration the bolt looseness of housing and broken kerve; thereby realize steady operation, improve the service life of this hammer mill.
A kind of hammer mill that is provided with above-mentioned hammer mill damping device that the utility model provides, because above-mentioned hammer mill damping device has above-mentioned technique effect, therefore the hammer mill that, is provided with this hammer mill damping device also has corresponding technique effect.
Accompanying drawing explanation
The accompanying drawing that forms a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Figure 1 shows that the perspective view of the utility model hammer mill.
Figure 2 shows that the perspective view of the utility model hammer mill damping device.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the utility model provides a kind of hammer mill damping device, and this hammer mill damping device is arranged in hammer mill, the damage causing because of high vibration to reduce hammer mill.
This hammer mill damping device 1 is arranged between the housing 2 and broken kerve 3 of hammer mill, to reduce the vibration between housing 2 and broken kerve 3.This hammer mill damping device 1 comprises steel cushion block 11 and flexible member 12, and this steel cushion block 11 arranges with these flexible member 12 intervals.At least each of the quantity of this steel cushion block 11 and flexible member 12.
Take this hammer mill damping device 1 is below arranged on hammer mill as example is illustrated.
The broken kerve 3 of this hammer mill is for carrying this housing 2, this hammer mill damping device 1 and coal stone.Particularly, this fragmentation kerve 3 comprises two ledges that are oppositely arranged 31 and connects the base plate 32 of two ledge 31 bottoms and the middle plate 33 at two ledge 31 middle parts of connection.This ledge 31 is for carrying this hammer mill damping device 1 and this housing 2.In this, plate 33 is for carrying coal stone.
This hammer mill damping device 1 is arranged on this ledge 31.This hammer mill damping device 1 is for reducing the vibration between housing 2 and broken kerve 3.In the present embodiment, this flexible member 12 is rubber blanket, and it has the effect of buffering, damping.This rubber blanket is preferably by polyurethane to be made.On this hammer mill damping device 1, offer through hole, this through hole comprises and is opened in the first through hole 111 on this steel cushion block 11 and is opened in the second through hole 121 on this rubber blanket, corresponding with this first through hole 111.This first through hole 111 and this second through hole 121, for construction bolt 9, are fixed between this housing 2 and this fragmentation kerve 3 this hammer mill damping device 1.In order to prevent relatively moving between this steel cushion block 11 and this rubber blanket, on this steel cushion block 11, offer the first via hole 112, on this rubber blanket, offer second via hole 122 corresponding with this first via hole 112, bearing pin 8 is installed in this first via hole 112 and this second via hole 122.Like this, can reduce the probability that relatively moves between this steel cushion block 11 and this rubber blanket, can prevent from producing because relatively moving between this steel cushion block 11 and this rubber blanket excessive shearing force this bolt 9 is damaged.
This hammer mill is connected with this hammer mill damping device 1, this fragmentation kerve 3 by bolt 9.The motor 22 that is provided with broken hammer body 21 in the housing 2 of this hammer mill and drives this fragmentation hammer body 21 to rotate.This fragmentation hammer body 21 can carry out fragmentation to the coal stone on plate in this 33 under the driving of this motor 22.
This hammer mill damping device 1 not only has the effect that reduces the vibration between housing 2 and broken kerve 3, and by adjusting that the quantity of this steel cushion block 11 and flexible member 12 can regulate this fragmentation hammer body 21 and the distance between plate 33 in this, thereby realize the regulatory function of this hammer mill to coal stone particle diameter.Particularly, when the quantity of this steel cushion block 11 and flexible member 12 increases, can make this fragmentation hammer body 21 and the increase of the distance between plate 33 in this, thereby the particle diameter of pulverized coal stone is increased.When the quantity of this steel cushion block 11 and flexible member 12 reduces, can make this fragmentation hammer body 21 and in this distance between plate 33 reduce, thereby the particle diameter of pulverized coal stone is reduced.Therefore, this hammer mill can increase or reduce according to the size of required coal stone particle diameter the quantity of steel cushion block 11 and flexible member 12.
While having the hammer mill work of this hammer mill damping device 1, this motor 22 drives this fragmentation hammer body 21 to rotate and roll the coal stone on plate 33 in this, produces huge vibration simultaneously.In the process rolling; this fragmentation kerve 3 passes to this hammer mill damping device 1 by vibration; flexible member 12 bufferings, absorbing; reduce the vibration transmission of 2 of this fragmentation kerve 3 and housings; motor in effective protection hammer mill and hydraulic system etc.; prevent from because of huge vibration, making to connect the bolt looseness of this housing 2 and this fragmentation kerve 3, thereby realize steady operation, improve the service life of this hammer mill.
Being appreciated that this flexible member 12 is except above-mentioned rubber blanket, can also be spring, and this spring and this steel cushion block 11 intervals arrange.The position that this spring arranges is corresponding with the first through hole 111 on this steel cushion block 11, and this bolt 9 penetrates in this spring and the first through hole 111 so that this hammer mill damping device 1 is connected between this fragmentation kerve 3 and this housing 2.
The utility model embodiment also provides a kind of hammer mill, and this hammer mill is provided with above-mentioned hammer mill damping device.
Because above-mentioned hammer mill damping device has above-mentioned technique effect, therefore, the hammer mill with this hammer mill damping device also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not hereby repeat.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
