Description
Technical Field
The utility model relates to a novel cutting blade for smashing type grid sewage removing machine belongs to and smashes grid sewage removing machine technical field.
Background
The cutting blade in the crushing type grid sewage removing machine is a key point of the whole equipment and directly determines the crushing effect of the equipment. The cutting blade used by the prior crushing type grid sewage removing machine is not divided into a main blade and an auxiliary blade, and the shearing torque of the blade is not high. Install multiunit cutting blade on the arbor, can form great cutting gap at tooth portion during rotatory cutting for particulate matter volume after the breakage is great, and softer debris rubbish twines the parcel easily at cutting blade tooth portion, greatly reduced the broken cutting effect of blade, also shortened the life of blade.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: in view of the drawbacks of the prior art, a new cutting blade for a crushing type grid sewage treatment machine is proposed to solve the above technical problems.
The utility model adopts the technical proposal that: a novel cutting blade for a crushing type grid sewage removing machine comprises a main blade and an auxiliary blade, wherein the main blade and the auxiliary blade are both processed by 3Cr13 steel, the main blade and the auxiliary blade are meshed with each other, a first cutter tooth is distributed on the circumference of the main blade, and a first through hole is formed in the center of the main blade; the circumference of the auxiliary blade is distributed with a second blade tooth, and the center of the auxiliary blade is provided with a second through hole.
The utility model discloses in: the first cutter teeth are uniformly distributed on the circumference of the main blade and are in a gear-shaped structure, and the number of the first cutter teeth is 11.
The utility model discloses in: the second cutter teeth are uniformly distributed on the circumference of the auxiliary blade and are in a ratchet-shaped structure, and the number of the second cutter teeth is 7.
The utility model discloses in: the first through hole and the second through hole are regular hexagonal holes.
The utility model discloses in: and the first cutter teeth and the second cutter teeth are both provided with cutting edges.
After the technical scheme is adopted, the beneficial effects of the utility model are that: the utility model discloses simple structure, reasonable in design has the branch of main blade and vice blade, and the blade moment of torsion that shears is high, can guarantee that the blade has good mechanical properties and longer life, and debris rubbish is difficult for twining the jam, and whole broken cutting effect is outstanding.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1. a main blade; 2. a secondary blade; 3. a cutter tooth I; 4. a cutter tooth II; 5. a first through hole; 6. and a second through hole.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As can be seen from figure 1, the novel cutting blade for the crushing type grid sewage removing machine comprises a main blade 1 and an auxiliary blade 2, wherein the main blade 1 and the auxiliary blade 2 are both made of 3Cr13 steel, the main blade 1 is meshed with the auxiliary blade 2, cutter teeth I3 are distributed on the circumference of the main blade 1, and a through hole I5 is formed in the center of the main blade 1; the circumference of the auxiliary blade 2 is distributed with a second blade tooth 4, and the center of the auxiliary blade 2 is provided with a second through hole 6; the first through hole 5 and the second through hole 6 are regular hexagonal holes. The radius from the central point of the regular hexagonal hole in the primary blade 1 to the most extensive extent thereof is the same as the radius from the central point of the regular hexagonal hole in the secondary blade 2 to the most extensive extent thereof. The cutter teeth I3 are uniformly distributed on the circumference of the main blade 1 and are in a gear-shaped structure, and the number of the cutter teeth I is 11. The second cutter teeth 4 are uniformly distributed on the circumference of the auxiliary blade 2 and are in a ratchet-shaped structure, and the number of the second cutter teeth is 7. And the knife teeth I3 and the knife teeth II 4 are both provided with knife edges.
Because the number of teeth of the main blade 1 is more, the cutter teeth which are distributed finely are formed, and after the cutter teeth are assembled with the auxiliary blade 2, the cutting and crushing efficiency of the blades can not be weakened, and a larger cutting gap can not be formed, so that the volume of cut particles can be well controlled.
Additionally, the utility model discloses when equipment moves, main blade 1 is the spiral cutting of rotating in opposite directions with vice blade 2 in the space, has avoided the cutting atress inhomogeneous, has effectively improved the life of blade.
The utility model discloses because main blade 1 adopts different number of teeth and shape structure with vice blade 2, and has changed the drive ratio through gear drive, forms two blade differential operation for the blade has self-cleaning function, can improve the situation of softer debris rubbish winding parcel at blade tooth portion greatly. Meanwhile, after the surface of the blade is subjected to heat treatment, the hardness of the cutting blade teeth can reach HRC 45-50, and the central hole part of the blade can also keep enough toughness.
The above description is directed to the specific embodiments of the present invention, but the present invention is not limited to the above description. Any equivalent modifications and substitutions to the present embodiments are within the scope of the present invention for those skilled in the art. Accordingly, variations and modifications in equivalents may be made without departing from the spirit and scope of the invention, which is intended to be covered by the following claims.
