Abstract
The utility model relates to a charging device for a single crystal furnace. A fixing support of the device is mounted on a cylinder body, a left half cone and a right half cone are positioned at the lower part of the cylinder body and respectively connected with one end of a left telescopic rod and one end of a right telescopic rod, the left telescopic rod and the right telescopic rod are movably arranged on the fixing support, and a moving track is arranged on the fixing support; a screw rod is arranged at the other end of the right telescopic rod, and the screw rod can be engaged with the left telescopic rod; or the screw rod is arranged at the other end of the left telescopic rod, and the screw rod can be engaged with the right telescopic rod. By adopting the charging device provided by the utility model, a new channel can be increased for charging, and the telescopic rods can be prevented from being eccentric and stuck by automatically adjusting the gravity, so that the blockage phenomenon can be avoided.
Description
Technical field
The utility model relates to a kind of single crystal growing furnace feeding device.
Background technology
The single crystal growing furnace feeding device using at present, by being located at the expansion link on the fixed support on cylindrical shell top, open after the cone of bottom, just start to add from space between cone and cylindrical shell silicon material, this device is in reinforced process, because easily causing expansion link bias, center of gravity imbalance blocks blockage phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of single crystal growing furnace feeding device that can prevent that latch up phenomenon from occurring.
The technical scheme that the utility model is taked is: a kind of single crystal growing furnace feeding device, fixed support is arranged on cylindrical shell, left hemicone is positioned at cylindrical shell bottom and is connected with one end of left expansion link and right expansion link respectively with right hemicone, left expansion link and right expansion link are movably arranged on fixed support, it is characterized in that being provided with moving track on fixed support; On the right expansion link the other end, being provided with screw rod and screw rod can be connected mutually with left expansion link, or on the left expansion link the other end, is provided with screw rod and screw rod can be connected mutually with right expansion link.
Adopt the utility model, can increase new passage reinforced, by automatic adjustment gravity, prevent that expansion link bias from blocking, thereby avoid latch up phenomenon to occur.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure, sequence number represents: cylindrical shell 1, fixed support 2, moving track 3, left expansion link 4, right expansion link 5, right hemicone 6, screw rod 7 and left hemicone 8.
Embodiment
Below the utility model is described in further detail.
With reference to Fig. 1, this single crystal growing furnace is arranged on cylindrical shell 1 with the fixed support 2 of feeding device, left hemicone 8 is positioned at cylindrical shell 1 bottom and is connected with one end of right expansion link 5 with left expansion link 4 respectively with right hemicone 6, left expansion link 4 and right expansion link 5 are movably arranged on fixed support 2, on fixed support 2, be provided with moving track 3, on the other end of right expansion link 5, be provided with bent bright screw rod 7 and the screw rod 7 of band and can be connected mutually with left expansion link 4 (also can on the other end of left expansion link 4, be provided with bent bright screw rod 7 and the screw rod 7 of band can be connected mutually with right expansion link 5).During use, when simultaneously movable downwards by left expansion link 4 and right expansion link 5, left hemicone 8 and right hemicone 6 are separated and produce gap with cylindrical shell 1, hand screw 7 simultaneously, left expansion link 4 and right expansion link 5 are in the mutual reversing motion of moving track 3, and left hemicone 8 and right hemicone 6 are separated, the interval producing between left hemicone 8 and right hemicone 6 is new reinforced passage, because this new reinforced passage is rectilinear, generally can not stop up, even if being separated with cylindrical shell 1 and producing gap location, left hemicone 8 and right hemicone 6 there is reinforced latch up phenomenon, cause left expansion link 4 and right expansion link 5 bias to block, and along with gravity constantly alleviates, left expansion link 4 and right expansion link 5 can reset by nature, thereby avoid latch up phenomenon to occur.After reinforced, as long as upwards pack up left expansion link 4 and right expansion link 5, and reverse hand screw 7, left hemicone 8 and right hemicone 6 are closed up again, restore to the original state.
