18 with rotated forward under the action of thread bush 21 so that the silicon material in inner cylinder 23 rotates, compared to silicon material under static condition
It crushes, crushing effect is more preferable.Since thread bush 21 and turntable 32 are rotatablely connected, and turntable 32 and inner cylinder 23 are rotatablely connected, therefore interior
Turntable 32 not can rotate when cylinder 23 rotates, and will not impact to gear set.In addition, knife rest 13 is able to drive knife when moving down
Protection cylinder 22 on frame 13 moves down, and protection cylinder 22 is inserted into inner cylinder 23 sieve pore 11 blocked on inner cylinder 23, and thus, it is possible to keep away
Exempt from silicon material when inner cylinder 23 rotates forward in it to throw away from sieve pore 11.
When knife rest 13 moves up, protection cylinder 22 is extracted out of inner cylinder 23, and the sieve pore 11 on inner cylinder 23 exposes, while the
One lead screw 18 is extracted from thread bush 21, and inner cylinder 23 rotates backward under the action of the first lead screw 18 and thread bush 21, to make
The silicon material obtained in inner cylinder 23 rotates again.The lesser silicon material of partial size is thrown out of from sieve pore 11 to outer cylinder by centrifugal force in inner cylinder 23
In 1, the biggish silicon material of partial size is then trapped in inner cylinder 23, is achieved in the screening of silicon material.In addition, energy when knife rest 13 moves up
Enough coarse fodder crushing knife 15 is driven to move up, coarse fodder crushing knife 15 is not left in inner cylinder 23, therefore when silicon material is thrown away not will receive
The resistance of coarse fodder crushing knife 15 will not influence the screening effect of silicon material.
It after the completion of silicon material screening, is moved right using cylinder drive rack 20, to pass through driven wheel of differential 16 and second
Band movable knife rack 13 moves down lead screw 17 again.It controls the mobile distance of this rack gear 20 and is greater than the silicon material screening movement of hour rack 20
Distance, until the second lead screw 17 on knife rest 13 is disconnected with driven wheel of differential 16, the protrusion 12 on knife rest 13 is from rack
On sliding slot in fall off after close cylinder.Since protrusion 12 is with flexible, therefore protrusion 12 can be issued in the extruding force of knife rest 13
Raw deformation out of sliding slot to fall off.At the same time, as shown in Fig. 2, the coarse fodder crushing knife 15 on knife rest 13 is inserted into turntable 32

Sieve pore 11 on inner cylinder 23.
After coarse fodder crushing knife 15 is connect with spline housing 31, starting motor drives the positive and negative rotation of gear wheel 28, and gear wheel 28 is logical
It crosses shaft 30 and drives the positive and negative rotation of turntable 32.Since coarse fodder crushing knife 15 passes through spline housing 31 at this time and turntable 32 connects, thus it is thick
Expect the also positive and negative rotation under the drive of turntable 32 of crushing knife 15, to carry out separating twice to the silicon material in inner cylinder 23, crushes effect
Fruit is more preferable.
Coarse fodder crushing knife 15 is able to drive knife rest 13 and rotates forward when rotating forward, it should be noted that when practical operation
Need to guarantee that knife rest 13 will not offset with inner cylinder 23, i.e. guarantee knife rest 13 there are enough spatial rotationals.Knife rest 13 drives first
Thick stick 18 rotates in thread bush 21, can not move since thread bush 21 is welded on inner cylinder 23, therefore energy when the rotation of the first lead screw 18
Enough band movable knife racks 13 move up.Knife rest 13 then drives coarse fodder crushing knife 15 to move up, since 15 spline of coarse fodder crushing knife connects
It connects in spline housing 31, therefore will not influence it and move in the vertical direction.Auxiliary blade 14 on coarse fodder crushing knife 15 is by inner cylinder
Silicon material in 23 pushes up, and silicon material is avoided to be deposited in 23 bottom of inner cylinder, so that silicon material crushing is more uniform.Similarly, canine tooth
Wheel 28 is able to drive the first lead screw 18 when rotating backward and rotates backward, so that coarse fodder crushing knife 15 moves down, it is so anti-
It is multiple, enable to the silicon material in inner cylinder 23 by the shearing force on vertical direction, so that silicon material crushing effect is more preferable, while can also
So that silicon material is rolled above and below in inner cylinder 23, further improves the crushing effect of silicon material.
The circle number of the rotation of knife rest 13 is controlled by the circle number of the control rotation of gear wheel 28, thus 18 turns of the first lead screw of control
Dynamic circle number, and then control the length extracted from thread bush 21 of the first lead screw 18 so that knife rest 13 move up away from
From the length for being less than spline housing 31, therefore knife rest 13 moves upwardly without so that coarse fodder crushing knife 15 is detached from from spline housing 31.
Gear wheel 28 is able to drive the pinion gear 25 engaged and rotates when rotating, pinion gear 25 drives 35 turns of crushing shaft
It is dynamic, so that the fines crushing knife 36 on crushing shaft 35 be driven to rotate, thus the silicon material in outer cylinder 1 is crushed.Pinion gear 25
Revolving speed be greater than the revolving speed of gear wheel 28, therefore the crush force that the silicon material in fines crushing chamber 24 is subject in the same time be greater than it is interior
The crush force that silicon material in cylinder 23 is subject to, to meet the fines crushing requirement different with coarse fodder.
The present invention drives crushing shaft 35 quick using the rotational speed difference between gear wheel 28 and pinion gear 25, using pinion gear 25
Rotation, increase the shearing force that is subject to of fines, to prepare coarse fodder and fines simultaneously；With difference is respectively adopted in the prior art
Device prepare coarse fodder and fines, or change the degree of grinding of device and successively prepare coarse fodder and compared with fines, system of the invention
It is standby more efficient.
