Continuing with combining referring to Fig. 2 and Fig. 4, in the present embodiment, moving knife component 400 further includes being arranged in the first knife rest
421 and the second intermediate slide 441 between knife rest 431, intermediate slide 441 is substantially plate-like, is fixedly connected by welding
On main shaft 410, and it is coaxially disposed with main shaft 410.Along intermediate slide 441 circumferential uniform intervals setting there are three third connect it is convex
Rise 442 and three the 4th connection bumps 443, third connection bump 442 be arranged alternately with the 4th connection bump 443, and third company
It connects protrusion 442 to be substantially oppositely arranged with the first connection bump 422, the one end of the first moving knife 426 far from the first knife rest 421 is fixed to be connected
It connects in third connection bump 442.4th connection bump 443 is substantially oppositely arranged with the second connection bump 432, the second moving knife
433 one end far from the second knife rest 431 are fixedly connected in the 4th connection bump 443, so that the structure of moving knife component 400
More compact, save the cost.And by setting intermediate slide 441, thus in the crushing device of same model, the first moving knife
426 and second the length of moving knife 433 be increased, to increase cutting area under the premise of meeting reduces energy consumption, improve life
Produce efficiency.
The crushing device 010 provided in the embodiment of the present invention, when work, driving motor 210 drives moving knife by belt
The main shaft 410 of component 400 rotates, and then drives 433 turns of the first moving knife 426 and the second moving knife being fixedly connected on main shaft 410
Dynamic, the first moving knife 426 and the second moving knife 433 are alternately cut with two stationary knifes cooperations, while by by the first moving knife 426 and second
Moving knife 433 axially offsets setting along main shaft 410, can reduce the transient current of motor when cut, to reduce energy consumption, passes through
Experiments have shown that crushing device 010 provided in this embodiment is compared to existing along the broken of axial five moving knife of setting of main shaft 410
The energy consumption of device 010 is lower.Meanwhile, it is capable to noise when reducing broken.
The above is only a specific embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
