It should be noted that, if the number of cutter teeth 503 of the single tooth plate 502 is smaller than 6-8, the biting force of the hob 5 is increased, so that the driving force of a driving member (such as a motor, etc.) for driving the hob 5 to rotate is increased, and the energy consumption of the driving member is further increased; if the number of cutter teeth 503 of a single tooth 502 is greater than 6-8, the cutter teeth 503 on the tooth 502 are denser, and massive materials with larger sizes are difficult to be engaged. Specifically, if the number of cutter teeth 503 is greater than 6-8, the number of cutter teeth 503 which are in contact with the bulk material at the same time increases, so that the bulk material is difficult to be brought into the first crushing area between the cutter teeth 503 of the two sets of hob 5, and thus the material cannot be crushed effectively.

According to an embodiment of the present application, the smaller the distance between adjacent tooth plates 502 on the same rotating shaft 501, the larger the friction force between the adjacent tooth plates 502 and another set of tooth plates 502, so that the driving force of a driving member (such as a motor, etc.) for driving the hob 5 to rotate is increased, and the energy consumption of the driving member is further increased. Therefore, the interval between the adjacent tooth plates 502 on the same rotating shaft 501 is set to be 1.5mm-2.5mm, so that the particle size of the crushed materials can be ensured to meet the requirement, and simultaneously, the additional friction force generated in the operation process can be reduced, and the energy consumption of a driving piece is further reduced.

According to an embodiment of the present application, as shown in fig. 5 and fig. 7, the cutter teeth 503 of a plurality of tooth plates 502 on the same rotating shaft 501 form a cutter tooth group along the axial direction, when the tooth plates 502 are provided with a plurality of cutter teeth 503, corresponding cutter tooth groups formed by the cutter teeth are also multiple groups, in each cutter tooth group of the cutter teeth group, the cutter teeth 503 are mutually staggered so that a rotation displacement is formed between the cutter teeth 503 of every two adjacent tooth plates 502, i.e. the two adjacent tooth plates 502 have a certain deflection angle relative to the rotating shaft 501 so that the cutter teeth 503 are mutually rotationally dislocated, wherein the deflection directions of the tooth plates 502 can be clockwise or both anticlockwise, i.e. deflect along the same rotation direction, the deflection directions of the tooth plates 502 can also be partially clockwise, and the other part anticlockwise, i.e. deflect along different rotation directions, and can be correspondingly adjusted according to actual crushing conditions. The rotary potential difference is set through cutter teeth 503, so that the tooth plates 502 of the two groups of hob 5 can be guaranteed to be fully meshed with materials, and the crushing effect is improved.

In the related art, the orthographic projections of the cutter teeth 503 of the plurality of tooth plates 502 on the rotating shaft 501 of the hob 5 along the axial direction are generally overlapped, so that the pressure applied to the hob 5 is concentrated on the cutter teeth 503 along the axial direction, and after the massive materials or hard materials are crushed for a long time, the hob 5 is easily damaged. This application sets up rotatory potential difference through cutter tooth 503, can make the pressure that hob 5 received carry out corresponding distribution along rotatory potential difference, and the global dispersion of pivot 501 is followed to the pressure promptly, therefore, this application through this setting, can disperse the pressure of hob 5 cutter body, avoids the pressure too concentrated, is favorable to protecting hob 5, and then prolongs reducing mechanism's life.

According to one embodiment of the present application, the angle of the rotational head of the cutter teeth 503 of adjacent two teeth plates 502 is set to 4 ° -6 °.

The rotary potential difference angle is set to be 4-6 degrees, so that the manufacturability of the hob 5 body is met on the premise of meeting the engagement performance. On the other hand, just because of this cutter body structure, can realize smashing large-size bulk material or hard thing under the circumstances of low-speed operation to because of low rotational speed operation, make the reducing mechanism of this application embodiment can realize low noise work.

According to one embodiment of the present application, as shown in fig. 5 and 7, the cutter teeth 503 of the plurality of tooth plates 502 on the same rotating shaft 501 are gradually offset from each other along the axial direction by a certain deflection angle to form the rotating position difference of the above embodiment. Specifically, the rotary position difference between the cutter teeth 503 and 503 is 4 ° -6 ° (e.g. 5 °), and so on, so that a certain angle rotary position difference is formed between the adjacent cutter teeth 503 along the same deflection direction, thus ensuring that the hob 5 fully engages with the material, and simultaneously maximizing the pressure dispersion effect of the hob 5, and further protecting the hob 5.

According to an embodiment of the application, a driving member (not shown in the figure) is connected to the rotating shaft of the hob 5, the driving member drives the rotating shaft 501 to rotate so as to enable the hob 5 to rotate, the driving member is generally a motor, a motor and other devices, the hob 5 can be driven to be in a low-noise running state below 47 minutes, noise is prevented from being generated, and the use experience of the crushing device is improved. Specifically, the input voltage of the driving element is adjusted to reduce the rotation speed of the driving element, and the constant voltage is set to be 100V-120V (220V at full load), so that the driving element can output a constant low rotation speed, for example, 90RPM-120RPM, and noise can be greatly reduced under the condition of low voltage and low rotation speed compared with the full load state. In addition, if the material which is difficult to crush and has higher hardness is encountered, the input voltage of the driving piece can be increased in real time so as to meet the instantaneous high-torque requirement. When the crushing is successful, the input voltage of the driving member is restored to a low voltage state, so that the user always feels the low noise state in the whole process.
