The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described.

Embodiment 1, and shown in Fig. 1～6, a kind of reducing mechanism of present embodiment comprises the main shaft 1 that is rotated by motor-driven; Be fixed with rolling disc 2 on the main shaft 1, rolling disc 2 is provided with connecting hole 3, is provided with crushing knife tool 4 through connecting hole 3, and motor-driven main shaft 1 rotates; Main shaft 1 drives rolling disc 2 and rotates, and rolling disc 2 and then drive crushing knife tool 4 rotate, and the windage of present embodiment is little, reduces noise; Stationarity is good, and the inertia of rolling disc 2 is big, removes the design of hammer slice axis simultaneously, has alleviated the load of present embodiment; Compare with the reducing mechanism of same power, crushing knife tool 4 is more, and crushing effect is better; The production efficiency of present embodiment is high, can reduce the power consumption of pulverizer significantly, reduces the operating cost of pulverizer simultaneously significantly.

Present embodiment rolling disc 2 surfaces are circular, and it is on the concentric circles in the center of circle that rolling disc 2 is provided with the center that 3,4 connecting holes 3 of 4 connecting holes are uniformly distributed in rolling disc 2, and each rolling disc 2 of present embodiment is provided with the structure of 4 connecting holes 3 simultaneously; A hammer slice axis of prior art wears a lot of cutters, all cutters all one on the axis of hammer slice axis, and the cutter that drives of hammer slice axis is the arrangement of 3 row; When hammer slice axis drove the cutter rotation, power was concentrated, and the power that needs is big; Drive crushing knife tool 4 with rolling disc 2 now, when crushing knife tool 4 rotated at a high speed under main shaft 1 drives, crushing knife tool 4 was not less than 6 row and arranges; The arrangement of staggering of the crushing knife tool 4 of present embodiment, power decentralized, dynamics balance; Further cut down the consumption of energy, make the noise of present embodiment little simultaneously, balance is very good; Energy consumption is little, and increases row's number of crushing knife tool 4, and material is pulverized more tiny.

The rolling disc 2 that present embodiment is arranged on the main shaft 1 is 8, and each rolling disc 2 both sides is respectively arranged with 4 crushing knife tools 4, constitutes 64 crushing knife tools 4 altogether; The motor of 11KW, prior art are provided with 4 hammer slice axis and drive crushing knife tool 4, can only drive 48 crushing knife tools 4; This moment, the rotating speed of rolling disc 4 was 2000 rev/mins ~ 3900 rev/mins; And when using present embodiment, the rotating speed of 11KW motor rolling disc 4 can reach more than 4500 rev/mins, and 64 crushing knife tool 4 crushing effects are better; It is more tiny to pulverize the product that comes out, and energy-conservation.

The crushing knife tool 4 of present embodiment comprises cutter body 41, and cutter body 41 is circular rack saw sheet, and the outer rim of cutter body 41 is provided with cutter tooth 42; Cutter body 41 offers installing hole 43 in non-home position, and crushing knife tool 4 is arranged at rolling disc 2 through installing hole 43, the crushing knife tool 4 of sawtooth sheet; Can effectively smash high fiber, high humility materials such as husk, wheat husk fast; Increase substantially crush efficiency, and crushing knife tool 4 is difficult for being worn, also is difficult for being damaged.

The connecting hole 3 that present embodiment passes rolling disc 2 is provided with a pair of crushing knife tool 4 composition set of knives 5; The crushing knife tool 4 of forming set of knives 5 is arranged at the both sides of rolling disc 2 respectively; This design can rationally utilize the useful space of pulverizing chamber; In the useful space more crushing knife tool 4 is set, helps improving the operating efficiency of present embodiment.

Cutter body 41 surfaces of present embodiment are rounded, and crushing knife tool 4 is provided with 4 installing holes 43, and the center that installing hole 43 is uniformly distributed in cutter body 41 is on the concentric circles in the center of circle; In the process of when crushing knife tool 4 is being worked, rotating at a high speed, the centrifugal force of rotation during owing to work, installing hole 43 easy deformation; Further cause whole crushing knife tool 4 distortion, crushing effect is poor, and crushing knife tool 4 has only a side that material is pulverized in the course of the work simultaneously; This side is an active side, and long-time the use can be worn and torn, and an other side does not play pulverization; A plurality of installing holes 43 are set, can be therein crushing knife tool 4 because service time is long distortion the time, change installing hole 43 is fixing; One side that will not play pulverization makes active side into, increases the service efficiency of crushing knife tool 4, and the center with cutter body 41 is that the center of circle is provided with a through hole simultaneously; Can reduce the weight of crushing knife tool 4, reduce the load of reducing mechanism, further realize energy-conservation.

Present embodiment also includes screw rod 6, is arranged with nut on the screw rod 6, is connected through screw rod 6 and nut between crushing knife tool 4 and the rolling disc 2; Screw rod 6 is equipped with the location slightly; Spacing slightly on screw rod 6 through the location between crushing knife tool 4 and the rolling disc 2, the crushing knife tool 4 of present embodiment is the center rotation with screw rod 6, when rotating at a high speed under the drive at motor; The arrangement of staggering automatically of different crushing knife tools 4; Certainly crushing knife tool 4 of the present invention can be completely fixed on the rolling disc 2, and crushing knife tool 4 is not limited to screw rod 6 with connected mode between the rolling disc 2 and is connected, and can also connect through other modes; Such as welding, only otherwise paying the connected mode that the method for creative work obtains all falls into protection scope of the present invention.

Embodiment 2; Like Fig. 7; Be that with embodiment 1 difference a connecting hole 3 that passes rolling disc 2 is provided with a crushing knife tool 4, crushing knife tool 4 is arranged at the same side of rolling disc 2, and crushing knife tool 4 is arranged at rolling disc 2 the same sides also can reach good crushing effect.

Embodiment 3, like Fig. 8, are that with embodiment 1 difference crushing knife tool 4 is the both sides that are distributed in rolling disc 2, and to each connecting hole 3, crushing knife tool 4 is single settings, are not provided with in pairs.

Embodiment 4; Like Fig. 9, be that with embodiment 1 difference crushing knife tool 4 is distributed in rolling disc 2 both sides; To each connecting hole 3; Have crushing knife tool 4 single settings and two kinds of situation are set in pairs, the crushing knife tool 4 of the set of knives 5 that is provided with in pairs is distributed in the both sides of rolling disc 2, and two crushing knife tools 4 of set of knives 5 of the present invention can be distributed in the same side of rolling disc 2.

The present invention can adjust the quantity of installing hole 43 of quantity and crushing knife tool 4 of quantity, the connecting hole 3 of rolling disc 2 as required, if only be that the change of these quantity all falls into protection scope of the present invention through performing creative labour.

Should be noted that at last; Above embodiment is only in order to explain technical scheme of the present invention; But not to the restriction of protection domain of the present invention, although with reference to preferred embodiment the present invention has been done explanation at length, those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the essence and the scope of technical scheme of the present invention.
