Summary of the invention:
The purpose of this invention is to provide a kind of two groups of blade all-in-one-pieces three bites of formula that stagger dorsad, be convenient to Chinese caterpillar fungus and pulverize, cutter is realized the preliminary pulverizing of Chinese caterpillar fungus, and bottom knife is realized the meticulous pulverizing of Chinese caterpillar fungus.
Above-mentioned purpose realizes by following technical scheme:
A kind of two groups of blade all-in-one-pieces three bites of formula that stagger dorsad, its composition comprises: cutter shaft, described cutter shaft inside has centre bore, the upper end of described centre bore is screwed hole, described screwed hole is connected with motor shaft, the two ends of described cutter shaft have last bite group respectively, following bite group, the described bite group that goes up, described bite group down and described cutter shaft are one, the described bite group that goes up has 3 upward cutting tips, described bite group down has 3 following cutting tips, and described upward cutting tip and described cutting tip down are for staggering dorsad.
Described two groups of blade all-in-one-pieces three bites of formula that stagger are dorsad describedly gone up cutting tip, described cutting tip down has 2 blades respectively, and the described length that goes up cutting tip is less than the length of cutting tip down.
Described two groups of blade all-in-one-pieces three bites of formula that stagger dorsad, it is described that to go up cutting tip be 45 °, the described cutting edge angle of cutting tip down is 40 °, describedly goes up cutting tip, the described ridge angle of elevation of cutting tip down is 30 °.
Beneficial effect:
Cutter shaft of the present invention and cutting tip are made one, and cutting tip is twolip, three-chip type design, are divided into two groups up and down, last bottom knife rotates in the cutting chamber simultaneously can form stable smoothness, be convenient to Chinese caterpillar fungus and pulverize, cutter is realized the preliminary pulverizing of Chinese caterpillar fungus, and bottom knife is realized the meticulous pulverizing of Chinese caterpillar fungus.
The present invention is two groups of blade one up and down, and the interstitial hole top end is attacked the M1.6 screw thread, directly do with motor shaft to be connected cooperation.The thread rotary orientation of screwed hole is corresponding with the motor direction of rotation, makes the threaded engagement place more change more tight playing with the motor rotation and loosens effect.
Two blades up and down of the present invention are that the back-to-back formula that staggers is arranged, in the course of work, can form the flow field of circulating up and down, are beneficial to raising and beat powder efficient, guarantee to beat the opaque amount

The specific embodiment:
Embodiment 1:
A kind of two groups of blade all-in-one-pieces three bites of formula that stagger dorsad, its composition comprises: cutter shaft 1, described cutter shaft inside has centre bore 2, the upper end of described centre bore is screwed hole 3, described screwed hole is connected with motor shaft, the two ends of described cutter shaft have last bite group 4 respectively, following bite group 5, the described bite group that goes up, described bite group down and described cutter shaft are one, the described bite group that goes up has 3 upward cutting tips 6, described bite group down has 3 following cutting tips 7, and described upward cutting tip and described cutting tip down are for staggering dorsad.
Embodiment 2:
According to embodiment 1 described two groups of blade all-in-one-pieces three bites of formula that stagger dorsad, describedly go up cutting tip, described cutting tip down has 2 blades respectively, the described length that goes up cutting tip is less than the length of cutting tip down.
Embodiment 3:
According to embodiment 1 or 2 described two groups of blade all-in-one-pieces three bites of formula that stagger dorsad, described upward cutting tip is 45 °, the described cutting edge angle of cutting tip down is 40 °, and described upward cutting tip, the described ridge angle of elevation of cutting tip down are 30 °.
