Description

Moving cutter disc of crusher

Technical Field

The utility model belongs to the technical field of crushers, and particularly relates to a movable cutter disc of a crusher.

Background

With the development of science and technology, agriculture and industry are more and more biased towards mechanical automation, rice is one of staple food used in daily life, the rice can be processed into various other foods for use, and the rice needs to be smashed in the rice processing process. Traditionally, the grinding and crushing are carried out by using a stone mill or a grinding wheel mill, the crushing fineness is poor, and after crushing, malignant impurities such as gravel can be doped, so that the quality is influenced. At present, the rubbing crusher is adopted to smash rice more, is equipped with pivoted blade disc in the rubbing crusher, and the rice is smashed at the in-process through the blade disc, and current rubbing crusher's crushing fineness is poor, and the reason lies in the time of rice when leading to the blade disc short, and kibbling time is short, and kibbling effect is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing the movable cutter disc of the grinder, which has high grinding fineness and good grinding effect.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

the utility model provides a cutter head of rubbing crusher, includes the disk body, the preceding terminal surface of disk body be equipped with the crushing circle that the multichannel is concentric circles form and distributes, every way is smashed the circle and is all contained a plurality of sword teeth along circumference evenly distributed, is equipped with the sword groove between two adjacent sword teeth, the tank bottom surface in sword groove does not meet with the preceding terminal surface of disk body, two adjacent sword teeth of smashing the circle are not on same straight line, terminal surface center department is equipped with convex frustum forward before the disk body, the axle center department of frustum is equipped with the through-hole that runs through.

Furthermore, the front end faces of the cutter teeth are all positioned on a plane parallel to the end face of the movable cutter head.

Furthermore, a plurality of crushing rings are distributed at equal intervals along the radial direction of the disc body.

Furthermore, an acute included angle is formed between the center line of the cutter groove and the diameter line of the disc body.

Furthermore, the thickness of the cutter teeth in the radial direction decreases progressively from back to front along the front-back direction of the disk body.

Furthermore, the number of the crushing rings is three.

Furthermore, a key groove is formed in the inner wall of the through hole.

Further, the inner diameter of the innermost crushing ring is larger than the maximum outer diameter of the frustum.

The utility model has the beneficial effects that: by adopting the scheme, the method has the advantages that,

the cutter grooves form a labyrinth type discharging channel, the movement path of materials is changed, the crushing time is prolonged, the crushing fineness is improved, and the crushing effect is greatly improved.

Drawings

The foregoing and other objects, features, and advantages of the utility model will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

FIG. 1 is a schematic diagram of an embodiment of the present invention.

Fig. 2 is a side view of one embodiment of the present invention.

FIG. 3 is a top view of an embodiment of the present invention.

Fig. 4 is a schematic diagram of another embodiment of the present invention.

Wherein: 1 is a disk body, 11 is a frustum, 12 is a through hole, 2 is a crushing ring, 21 is a cutter tooth, and 22 is a cutter groove.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

Example 1: referring to fig. 1-3, a movable cutter head of a grinder comprises a disk body 1, three grinding rings 2 distributed concentrically are arranged on the front end surface of the disk body 1 with the circumferential direction of the disk body 1 as the front-back direction, each grinding ring 2 comprises a plurality of cutter teeth 21 uniformly distributed along the circumferential direction, a cutter groove 22 is arranged between every two adjacent cutter teeth 21, the cutter teeth 21 of the two adjacent grinding rings 2 are not on the same straight line, an acute included angle is formed between the central line of the cutter groove 22 and the diameter line of the disk body 1, namely, the central line of the cutter groove 22 is not parallel to the radial direction, a frustum 11 protruding forwards is arranged at the center of the front end surface of the disk body 1, a through hole 12 is arranged at the axis of the frustum 11, a key groove is arranged at the inner wall of the through hole 12, the through hole 12 is used for installing the movable cutter head, after installation, the movable cutter head is matched with the stationary cutter head, the cutter teeth of the movable cutter head are matched with the cutter teeth of the stationary cutter head, the inner diameter of the innermost grinding ring 2 is larger than the maximum outer diameter of the frustum 1, frustum 11 forms the material chamber that temporarily holds the material with the crushing circle 2 of the innermost side, the outer wall of frustum 11 can make the material faster, more smooth and easy to smash 2 movements of circle, the sword groove 22 of circle 2 forms the discharging channel of labyrinth is smashed to the third track, the material is the S type along labyrinth discharging channel and moves out, at the in-process that moves out, grind by the broach tooth, cut, smash, the structure of movable cutter head makes the route change of material motion, crushing time has been increased, the material is smashed many times, kibbling fineness is higher, kibbling quality obtains very big improvement.

Specifically, the tank bottom surface of sword groove 22 does not meet with the preceding terminal surface of disk body 1, this kind of structure makes disk body 1 have fine support nature to sword tooth 21, the connectivity of sword tooth with the disk body has been strengthened, the structural strength of sword tooth has been improved, make the difficult fracture of sword tooth, the time of using has been prolonged, three crushing circles 2 distribute along disk body 1's radial equidistance, the preceding terminal surface of sword tooth 21 all is in on the plane parallel with the moving cutter head terminal surface, this kind of structure is convenient for cooperate with quiet cutter head, the improvement is smashed the fineness.

Example 2: the present embodiment is different from embodiment 1 in that, in the present embodiment, referring to fig. 4, the cutter teeth 21 are tapered teeth or trapezoidal teeth, and the thickness of the cutter teeth 21 in the radial direction decreases from back to front along the front-back direction of the tray body 1.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiment according to the present invention are within the scope of the present invention.
