Second spring is provided on bottom end, the second spring is connected to the upper surface of elastic stripper, and second spring, which is in, stretches shape
State.
In the prior art, fall between two rollers of double-roll crusher that carry out broken silicon material amount unevenly and continuous.
It leads to the problem of there are many reason of this, for example, feeding amount is simultaneously uneven and connects when conveyer conveys silicon material to double-roll crusher
It is continuous；In feed hopper, there are gap between larger-size silicon material, the size in gap is uncontrollable and not it is contemplated that therefore
It is possible that there is aerial phenomenon, i.e., a certain silicon material is used as fulcrum, in the presence of the silicon material, most of silicon material stacking above it without
Method continuously falls, and when the silicon material removes, the silicon material of stacked on top may fall rapidly in a short time, cause two rollers
Silicon material amount between son is uneven, discontinuous.It is finally generating the result is that the granularity of broken silicon material is uneven, after being unfavorable for
Continuous separation and smelting technology, meanwhile, the silicon material largely passed through in the short time is not only crushed not exclusively, but also can be made to roller
At serious abrasion, improves the maintenance cost of equipment, reduces the service life of equipment.
In order to solve the problems, such as the silicon material amount being crushed between two rollers fluctuation, the present invention provides a kind of modified double rollers
Formula crusher.The crusher is like the prior art: including shell and positioned at the feed hopper of housing tip, by conveyer

Actual demand adjusts the elastic stripper elastic force to be overcome, and then adjusts the weight for the silicon material born on elastic stripper
Power, so that operating flexibility is higher.
The present invention has passive and active two kinds of elastic stripper on-off modes.
Specifically, passive on-off mode are as follows: after silicon material enters enclosure interior, first in the upper of elastic stripper
Side stack, when the gravity of the silicon material of stacking be greater than the first spring, second spring elastic force when, elastic stripper moves straight down
It is dynamic, silicon material dropped down onto from the opening of elastic stripper and feed hopper bottom end below elastic stripper and eventually by roller gap into
Row is broken.When silicon material weight reduces, on elastic stripper the gravity of silicon material less than the first spring, second spring elastic force when,
Feed hopper bottom end is closed again, is dropped down onto below elastic stripper without silicon material at this time, and silicon material is accumulated again on elastic stripper.
Although passive on-off mode energy conservation, during discharge, with the silicon material weight on elastic stripper
It reduces, elastic stripper progressively closes off, and during the shutdown process, some larger-size silicon material may be sandwiched in feed hopper and bullet
Property stripper between, cause feeding funnel bottom part can not normal switching-off, the silicon material that the size is less than on elastic stripper then can be continuous
It is dropped down on positive stripper by opening, causes " failure collects " in a period of time.In order to solve this problem, the present invention mentions
Active on-off mode is supplied.
Active on-off mode are as follows: drive the piston rod of hydraulic cylinder to move up and down vertically by controlling hydraulic oil pump, in turn
It is moved up and down vertically by second spring band dynamic elasticity stripper, to switch feeding funnel bottom part.In switching process, the first bullet
Spring and second spring avoid elastic stripper and supporting table or feed hopper from generating fierce collision, effectively as buffer function
Protect elastic stripper.Active on-off mode can be independently operated, to preset and be opened or closed by controlling hydraulic oil pump
The time of elastic stripper opens or closes so that feed hopper is regular.Active on-off mode can also with it is passive
On-off mode is used cooperatively, and after appearance " failure collects ", is moved down unlatching feed hopper by controlling piston rod, is exhausted size
Feed hopper is closed after biggish silicon material.
By the combination of passive and active elastic stripper on-off mode, though the conveying capacity of conveyer it is discontinuous,
Unevenly, but it can collect and stack in the vertical section of feed hopper first into the intracorporal silicon material of shell, when gravity overcomes elasticity
The lower section of elastic stripper is fallen by the opening opened between elastic stripper and feed hopper just now after power, thus eliminate into
