Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The high-shear-performance double-shaft crusher shown in the attached drawings 1 to 5 comprises a crusher body 1, wherein a crushing cavity 2 is arranged in the crusher body 1, two crushing shafts 3 are transversely arranged in the crushing cavity 2, and the two crushing shafts 3 are adjacent in parallel and driven by a motor to rotate. A feeding hole is arranged above the crushing cavity 2. A plurality of groups of crushing blades 4 are arranged on the crushing shaft 3 along the axial direction, and the group of crushing blades 4 comprise a plurality of crushing blades 4 which are arranged along the circumferential direction of the crushing shaft 3 at equal angles. The schematic diagram of the internal structure of the crushing cavity is shown in fig. 2, and the crushing blades 4 on the two crushing shafts 3 are matched with the comb plate 7 to crush materials.

One side of broken blade 4 is provided with inclined plane 5, and broken blade 4 applys the component of circumference to the material through inclined plane 5, and the inclined plane place side of broken blade 4 with the group is the same, and the inclined plane place side of broken blade 4 of adjacent group is different mutually, and the axial component direction that broken blade 4 of adjacent group was applyed to the material is opposite, and then produces axial tearing and shearing action to the material, compares in traditional double-shaft crusher, the utility model discloses can produce extra axial component to the material, it is better to the shearing crushing effect of material.

As shown in fig. 3, the two crushing shafts 3 rotate in different directions, and both rotate in directions toward the sides close to each other. Two the inclined plane place side of the two sets of crushing blades 4 that correspond each other on broken axle 3 is different, and the direction of the axial force of applying is opposite, produces the axial shearing action of tearing, further promotes the utility model discloses the broken effect of cuting the material.

As shown in fig. 5, the inclined surface 5 is arranged along a partial edge of one side of the rotation direction of the crushing blade 4, so that the inclined surface 5 contacts with the material along with the rotation of the crushing shaft 3 and shears and crushes the material. The inclined plane 5 is in an inwards concave arc shape. The radius of the arc-shaped inclined surface 5 tends to become gradually larger from the bottom end to the top end of the crushing blade 4, and the radius of the arc-shaped inclined surface 5 tends to become gradually larger from one side to the other side of the rotating direction of the crushing blade 4. The inclined plane 5 that the arc set up to and the radius change of inclined plane 5, make crushing blade 4 sharper with the one side that the material meets, and also make crushing blade 4 have a process that increases gradually to the axial effort of material, and the degree that increases also increases gradually. Crushing blade 4 increases axial effort through arc inclined plane 5 after passing the material gradually, and the process of applying of axial effort is more reasonable, if inclined plane 5 is straight inclined plane, then inclined plane 5 can receive great axial effort at the beginning, leads to crushing blade 4 to break easily, shortens crushing blade 4's life.

A plurality of strip-shaped shearing teeth 6 are arranged on the inclined surface 5 at intervals, and the shearing teeth 6 extend from the bottom end of one side of the rotation direction of the crushing blade 4 to the top end of the other side of the rotation direction of the crushing blade 4. The arrangement of the shearing teeth 6 can increase the twisting effect of the inclined plane 5 on the material, so that the inclined plane 5 can apply axial acting force on the material.

The shearing teeth 6 are integrally towards the arc shape sunken in the bottom end of the crushing blade 4, and the shearing teeth 6 can gradually engage with the material along with the rotation of the crushing shaft 3 and tear the material for crushing. The radius of the arc-shaped shearing teeth 6 is gradually increased from one side of the rotation direction of the crushing blade 4 to the other side, and the tooth height of the shearing teeth 6 is gradually increased from the top end to the bottom end of the crushing blade 4, so that the meshing effect of the shearing teeth 6 on materials is from shallow to deep.

The space between a plurality of the shearing teeth 6 is gradually widened from one side to the other side of the rotating direction of the crushing blade 4, along with the rotation of the crushing shaft 3, the space between the adjacent shearing teeth 6 is changed, and the materials meshed between the adjacent shearing teeth 6 are further torn and crushed.

As shown in fig. 3, the crushing blades 4 are arranged along the radial direction of the crushing shaft 3, the crushing blades 4 of the same group are arranged at equal angles along the circumferential direction of the crushing shaft 3, and the crushing blades 4 of adjacent groups are arranged at intervals.

The crushing blades 4 are integrally in a square column shape, the top ends of the crushing blades 4 are arc-shaped, and the arc-shaped top ends of the crushing blades 4 on the same crushing shaft 3 are positioned on the same circle; the top of crushing blade 4 with follow be provided with the arc angle of indent between the both sides terminal surface of 3 circumference of broken axle, the setting of arc angle does benefit to the top of crushing blade 4 and bites the material.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
