Abstract
The utility model discloses a crescent crushing blade, and belongs to the technical field of crushers. The crescent crushing blade comprises a blade main body, wherein a mounting hole is formed at one end of the blade main body, and a bending which forms a certain angle with the panel part of the blade main body is arranged at the other end of the blade main body to form a bending part. A sawtooth is arranged on the side of the blade main body. The bending part can form a contact surface with a large area when the blade rotates at high speed, and can be directly and fully ground with crushed materials, so that the crushing space is effectively utilized, the crushing effect can be enhanced, and the crushing efficiency can be improved. At the same time, by combining the sawtooth on the side of the blade, the powdery products with fine particles can be produced.
Description
Technical field
The utility model relates to a kind of Disintegrating knife, belongs to the pulverizer technical field.
Background technology
Pulverizer is the cutting action by moving knife blade and stationary knife, reaches blade the impact of broken thing and collision are realized crushing function, and the moving knife blade is arranged on cutterhead, rotates with cutterhead.And existing moving knife blade is the straight plate of strip, although this shape can be carried out effective fragmentation to broken thing, but straight plate can only be pulverized in the space of its thickness range in rotary course, gap between two blades can not directly contact with crushed material, affect efficient, restricted the crushing effect of pulverizer.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of crescent Disintegrating knife, forms contact-making surface in a big way, effectively utilizes comminuting space, can strengthen crushing effect, improves crush efficiency.
The utility model is achieved by the following technical solution: a kind of crescent Disintegrating knife, it comprises vane body, one end of vane body is manufactured with installing hole, and the other end of vane body has the bending angled with the flat part of vane body, forms bending part.
Be manufactured with sawtooth on the side of described vane body.
Described sawtooth is take described bending part as starting point, and the development length of sawtooth is not less than half of side edge length of vane body.
Be manufactured with chamfering on the side of described vane body.
Angle between the flat part of described bending part and described vane body is 15～45 degree.
The beneficial effects of the utility model are: the utility model vane body has bending part, can form the larger area contact-making surface when the blade High Rotation Speed, become " line cutting " and be " face cutting ", can be directly and crushed material fully grind, cut, impact, and enhancing swirling eddy, effectively utilize comminuting space, can strengthen crushing effect, improve crush efficiency.Simultaneously, in conjunction with the sawtooth of blade side, can carry out to crushed material the grinding of refinement more, contact-making surface and the angle of increase cutting, impacting and grinding can be produced the more tiny powder product of particle.

Fig. 5 is a kind of mounting means schematic diagram of the utility model.
In figure, 1, sawtooth; 2, chamfering; 3, vane body; 4, installing hole; 5, bending.
The specific embodiment
A kind of crescent Disintegrating knife as shown in drawings, it comprises vane body 3, and an end of vane body 3 is manufactured with installing hole 4, and the other end of vane body 3 has the bending 5 angled with the flat part of vane body 3, forms bending part.This bending can be arc, also with the bending of corner angle.
Be manufactured with sawtooth 1 on the side of described vane body 3, can carry out to crushed material the grinding of refinement more, contact-making surface and the angle of increase cutting, impacting and grinding strengthen crushing effect, can produce the more tiny powder product of particle.This embodiment can be called " zigzag crescent moon sickle ".
Described sawtooth 1 is take described bending part as starting point, and the development length of sawtooth 1 is not less than half of side edge length of vane body 3.
Be manufactured with chamfering 2 on the side of described vane body 3.Make the blade sidepiece form blade, the pulverizing that is more suitable for becoming more meticulous.Described sawtooth 1 can be produced on the hypotenuse of chamfering 2 formation, and to increase the angle of saw cut, the profile of chamfering and sawtooth can be with reference to figure 3 and two kinds of embodiment of Fig. 4.
Angle between the flat part of described bending part and described vane body 3 is 15～45 degree.
During use, the utility model is arranged on cutterhead by installing hole, during with the cutterhead High Rotation Speed, can form the larger area contact-making surface when the blade High Rotation Speed, become " line cutting " and be " face cutting ", can be directly and crushed material fully grind, cut, impact, and enhancing swirling eddy, effectively utilize comminuting space, strengthen crushing effect, improve crush efficiency.Simultaneously, in conjunction with the sawtooth of blade side, can produce the more tiny powder product of particle.The utility model can be arranged on according to the mode of Fig. 5 on the cutter shaft of cutterhead, also can use with the blade unit of straight plate shape.
