Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the present invention is described further:
A kind of cutter structure of single-shaft shredder as shown in figs. 1-7 including hollow cutter shaft 10, moving knife 20 and is determined
Knife is formed with waterway 13 in the inside of cutter shaft 10;Multiple first mounting grooves 15 are offered in the outer surface of cutter shaft 10 simultaneously, it should
It is corresponded in first mounting groove 15 and the moving knife 20 is installed, moving knife 20 is detachably arranged in the first mounting groove 15.Separately
Outside, above-mentioned stationary knife is arranged at intervals with cutter shaft 10, and forms cutting gap between stationary knife and cutter shaft 10.Specific moving knife 20 includes knife
Seat 21 and blade 22, tool apron 21 are installed in first mounting groove 15;Blade 22 is connected on tool apron 21, on blade 22
With the first cutting line 221, the second cutting line 222 and discharge groove 223, the first cutting line 221 and the second cutting line 222 are distinguished
The both sides of blade 22 are formed in, and before first cutting line 221 is located at the second cutting line 222 in the rotation direction of cutter shaft 10
Side.Above-mentioned discharge groove 223 is set between the first cutting line 221 and the second cutting line 222, and the both ends of discharge groove 223 connect respectively
Pass to the both sides of the face of blade 22.
When on the basis of the said structure, using the cutter structure of the present invention, which can be mounted on shredder
Intracavitary is torn up, it is specific now to install the tool apron 21 of moving knife 20 in first mounting groove 15, while the both ends of cutter shaft 10 are articulated in and are torn
The both ends of broken chamber, above-mentioned stationary knife are fixed on the both sides for tearing up chamber, and stationary knife is made to be located at the side of cutter shaft 10 and between cutter shaft 10
It is arranged at intervals, is rotated by motor band 20 axis 10 of moving knife on shredder, moving knife 20 can be formed between stationary knife on cutter shaft 10
Dissection cuts the material in the cutting gap.And due to first of the rotation direction upper knife edge 22 in blade
Cutting line 221 is the front positioned at the second cutting line 222, therefore during cutter shaft 10 rotates, the of 20 blade 22 of moving knife
One cutting line 221 and the second cutting line 222 successively can be contacted and be cut with material, and when such 10 per revolution of cutter shaft is same
The blade 22 of one moving knife 20 can carry out cutting twice, cutting force bigger, the material of easily broken hardness bigger, the blade of moving knife 20
22 abrasion is smaller, and consumes energy and reduce in the case of equal material.Meanwhile material is after the first cutting line 221 is cut
It can be discharged along discharge groove 223, and the dissection again through the second cutting line 222 is further cut so that material is cut
It is more tiny, while avoid material remain in cutting cutter hub on, cutting process is more smooth.
Certainly, coolant can be imported in the cooling chamber in above-mentioned cutter shaft 10, so as to reduce the temperature of cutter shaft 10, dropped simultaneously
The low temperature mounted on moving knife 20 on cutter shaft 10 reduces the abrasion of moving knife 20, improves working efficiency.In addition, moving knife 20 is detachable
The first mounting groove 15 being mounted on cutter shaft 10 in so that mounting structure of the moving knife 20 on cutter shaft 10 is stablized, and convenient for tearing open
Dress.
Preferably, cutter shaft 10 includes hollow 11 and two spindle nose 12 of axis body, and specific above-mentioned waterway 13 can be formed in axis
Inside body 11, and 13 both ends open of waterway, above-mentioned two spindle nose 12 are divided into the both ends of axis body 11 and for closing the opening,
Facilitate the processing of entire cutter shaft 10.In the present embodiment, above-mentioned spindle nose 12 can be fixed on axis body 11 in a welding manner
Both ends.
Further, it can be worn in an above-mentioned wherein spindle nose 12 and connect a water cooling tube 14, one end of the water cooling tube 14 is connected to
In waterway 13, the other end of water cooling tube 14 is connected with external water supply installation, for coolant is passed through in cutter shaft 10, convenient for water
Coolant in cold chamber 13 imports or export, can be replaced in time after the coolant temperature raising of waterway 13.
Preferably, also multiple air cooled lamps can be additionally provided in the side of cutter shaft 10, the outlet of each air cooled lamp is made to be right against institute
The surface of cutter shaft 10 is stated, specific each air cooled lamp can be mounted on shredder, cold air is so passed through in air cooled lamp, cold air is blown in knife
10 surface of axis reduces the temperature of cutter shaft 10 and moving knife 20, further improves the cutting-tool's used life and working efficiency.

And across moving knife 20 blade 22, if another plane Y70 perpendicular to the plane X60 and by cutter shaft 10 central axis, such as
This does the blade 22 of moving knife 20 section along the plane X60, and the intersection point of the first cutting line 221 and plane X60 is cut for first
Cutpoint 224, the intersection point of same second cutting line 222 and plane X60 are the second cut point 225, make the first cut point 224 and the
The line of two cut points 225 is 2 degree to 3 degree with angle formed by plane Y70, on the architecture basics, 221 He of the first cutting line
The distributing position of second cutting line 222 is not much different, conducive to gradually being cut to material.
Preferably, above-mentioned first cutting line, 221 and second cutting line 222 can be circular arc line, due to the characteristic of circular arc,
Multiple the first cut points 224 around blade rotation directional spreding can be formed on first cutting line 221, similarly in the second cutting line
Also the first cut point 224 that multiple rotation directions around cutter shaft 10 are distributed can be formed on 222, i other words in blade rotation first
Multiple first cut points 224 can successively cut material, and then material is again by the second cutting line 222 on cutting line 221
Multiple second cut points 225 successively cut so that only being cut to material there are one cut point when cutter shaft 10 rotates
It cuts, reduces the abrasion of the blade 22 of moving knife 20, while improve cutting force, further reduce energy consumption.
Preferably, the inner wall mask body of above-mentioned discharge groove 223 is alternatively arc surface, convenient for the discharge of material.
Preferably, helically line is distributed on cutter shaft 10 the multiple first mounting groove 15, is so corresponded and is mounted on
Moving knife 20 in first mounting groove 15 be also helically line be distributed in 10 surface of cutter shaft, further the cutter is being rotated in rotor
Continuous shear stress on direction.
Preferably, in the present embodiment, the second mounting groove 23 and mounting hole can be offered on the tool apron 21 of moving knife 20
24, mounting hole 24 is through the bottom wall of the second mounting groove 23;It is worn in mounting hole 24 and is connected to a bolt 40, the head storage of bolt 40
In in the second mounting groove 23, the tail portion of bolt 40 is screw-coupled to the bottom wall of the first mounting groove 15, is so spirally connected in mounting hole 24
The head of bolt 40 can be wrapped in the second mounting groove 23, during moving knife 20 is cut, even if the tool apron of moving knife 20
21 are impacted by material, and the side wall of mounting groove can also give one, the head reaction force of bolt 40, avoid bolt 40 be hit and
It loosens, the mounting structure of such moving knife 20 is more stablized.
Preferably, referring to Fig. 3 and Fig. 4, multiple grooves 16 are offered on cutter shaft 10, each groove 16 is made to be installed with each first
