Embodiment
For the ease of understanding the utility model, the utility model is more fully retouched below with reference to relevant drawings
State.Preferred embodiment of the present utility model is given in accompanying drawing.But, the utility model can come real in many different forms
It is existing, however it is not limited to embodiment described herein.On the contrary, the purpose for providing these embodiments is made to public affairs of the present utility model
The understanding for opening content is more thorough comprehensive.
It should be noted that when element is referred to as " being fixed on " another element, it can be directly on another element
Or can also have element placed in the middle.When an element is considered as " connection " another element, it can be directly connected to
To another element or it may be simultaneously present centering elements.
As depicted in figs. 1 and 2, it is the breaker bar of the preferred embodiment of the utility model one, including with outer circumference surface
11 blade 10, some cutting bodies 20 and some cutting grooves 30 on outer circumference surface 11 on outer circumference surface 11, cut
Cut body 20 and cutting groove 30 is staggered, cutting groove 30 has the first blade 31, for aiding in cutting body 20 to cut paper.
The center of blade 10 is provided with hexagonal mounting hole 12, for being passed through for knife rod, and installs breaker bar
In on knife rod.By setting mounting hole 12 hexagonal so that breaker bar is difficult relative knife in the case of high-speed rotation
Rod rotates, it is ensured that breaker bar can smoothly cut paper.
As shown in Fig. 2 the surface of blade 10, cutting body 20, cutting groove 30 is poly- to be provided with wear-resisting composite coating, wear-resisting compound painting
The thickness of layer is 1mm-3mm.In the present embodiment, the thickness of wear-resisting composite coating is preferably 2mm.
Wear-resisting composite coating includes the titanium carbide coating 40 and aluminum oxide coating layer 50 set gradually from inside to outside.Titanium carbide is applied
The setting of layer 40 and aluminum oxide coating layer 50 so that blade 10, cutting body 20 and cutting groove 30 are respectively provided with preferably wearability, is improved
The service life of breaker bar.
In the present embodiment, the thickness of titanium carbide coating 40 and aluminum oxide coating layer 50 is equal.
Cutting body 20 includes the tip 22 of one end of cutting body body 21 and connection cutting body body 21；Tip 22 is remote to be cut
It is the second linear blade 23 to cut one end of body body 21, and side of the tip 22 away from cutting body body 21 caves inward
Arcwall face, so that the second blade 23 is sharp, can be rapidly cut paper.
In the present embodiment, blade 10 and cutting body 20 are all made of Hardmetal materials, to increase crusher knife
The hardness of piece.
In the present embodiment, cutting body 20 is wholely set with blade 10, certainly, the cutting body 20 and blade 10 of this programme
Connected mode is not limited only to this, in other embodiments, and cutting body 20 is set with the split of blade 10, and cutting body 20 is connected by screw
Blade 10 is connect, this realizes being detachably connected for cutting body 20 and blade 10, need to change when abrasion occurs for some cutting body 20
When, without entirely broken blade is replaced, the cutting body 20 of the abrasion only need to be replaced, maintenance cost is reduced.
Cutting groove 30 has the bottom surface 33 of two relative side walls 32 and each side wall 32 of connection, each side wall 32 and outer circumference surface 11
Intersection be respectively formed the first linear blade 31；Each side wall 32 is bent away from the center position of cutting groove 30, with
Make the first blade 31 sharp, paper can be rapidly cut；The vertical range of first blade 31 to outer circumference surface 11 is less than the second blade
23 to outer circumference surface 11 vertical range, this causes the paper that the paper slip that the first blade 31 is cut out can be cut out than the second blade 23
Bar is thin.After paper is cut into rag paper bar by the second blade 23 on cutting body 20, the second blade 23 of cutting groove 30 can aid in cutting
Cut the rag paper bar that the first blade 31 of body 20 will go between adjacent cutting body 20 to chop up, so that the paper after cutting can be more preferable
Ground is recycled.
As shown in figure 3, the sectional view of the breaker bar for another embodiment of the utility model, the embodiment and above-mentioned reality
The distinctive points for applying example are：Breaker bar also includes the metal installation set 60 in mounting hole 12, and metal installation set 60 is led to
The connection blade 10 of trip bolt 70 is crossed, the screw head of trip bolt 70 is located in the counterbore that metal installation set 60 is set.In disintegrating machine
During blade carries out multiple dismounting with knife rod, the madial wall 32 of mounting hole 12 can wear and tear, very tight when wearing and tearing
During weight, breaker bar will be caused can not to be successfully installed on knife rod, it is necessary to be changed to whole breaker bar, led to
Cross and metal installation set 60 is set in the mounting hole 12, in the dismounting of breaker bar and knife rod so that knife rod can only wear and tear peace
Encapsulation, during replacing, only need to replace installation set, without whole breaker bar is replaced, reduce maintenance cost.
Above-mentioned breaker bar, by setting the cutting body 20 with the second blade 23, and is set with the first knife
The cutting groove 30 of sword 31, because the vertical range of the first blade 31 to outer circumference surface 11 is less than the second blade 23 to outer circumference surface 11
Vertical range, after the second blade 23 slits the paper into rag paper bar, the first blade 31 can aid in the second blade 23 to cut rag paper bar
Carefully, this not only enables paper to be chopped up and preferably recycled, and also causes blade to be difficult to be worn, improves crusher knife
The service life of piece.
Embodiment described above only expresses several embodiments of the present utility model, and it describes more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that for the common skill of this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
Protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
