Abstract
The utility model relates to a charging cylinder for a single crystal furnace. A fixing support of the charging cylinder 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 are 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 connected on a position-limiting part and movably arranged on the fixing support, a support track is arranged on the fixing support, a position-limiting part track is arranged on the position-limiting part, a left bolt and a right bolt are arranged on the position-limiting part, and the left bolt and the right bolt are respectively connected with the left telescopic rod and the right telescopic rod. By adopting the charging cylinder 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 casing drum for single crystal growing furnace.
Background technology
The single crystal growing furnace casing drum 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 casing drum for single crystal growing furnace that can prevent that latch up phenomenon from occurring.
The technical scheme that the utility model is taked is: a kind of casing drum for single crystal growing furnace, 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 connected on locating part and are movably arranged on fixed support, it is characterized in that being provided with bracket track on fixed support, on locating part, be provided with locating part track, left bolt and right bolt are arranged on locating part, and left bolt is connected with right expansion link with left expansion link respectively with right bolt.
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, left bolt 3, bracket track 4, locating part track 5, right bolt 6, right expansion link 7, right hemicone 8, left hemicone 9, left expansion link 10 and locating part 11.
Embodiment
Below the utility model is described in further detail.
With reference to Fig. 1, this fixed support 2 for the casing drum of single crystal growing furnace is arranged on cylindrical shell 1, left hemicone 9 is positioned at cylindrical shell 1 bottom and is connected with one end of right expansion link 7 with left expansion link 10 respectively with right hemicone 8, left expansion link 10 and right expansion link 7 are connected on locating part 11 and are movably arranged on fixed support 2, on fixed support 2, be provided with bracket track 4, on locating part 11, be provided with locating part track 5, left bolt 3 and right bolt 6 are arranged on locating part 11, and left screw rod 3 is connected with right expansion link 7 with left expansion link 10 respectively with right screw rod 6.
During use, when passing through locating part 11 by left expansion link 10 and right expansion link 7 activity downwards simultaneously, interval between left hemicone 9 and right hemicone 8 and cylindrical shell 1 starts to feed in raw material, when left expansion link 10 and right expansion link 7 are when coming downwards to a certain degree, by nut, screw rod is moved respectively to both sides left bolt 3 and right bolt 6, left expansion link 10 and right expansion link 7 are along separating in bracket track 4 and locating part track 5 simultaneously, like this, the interval producing between left hemicone 9 and right hemicone 8 is new reinforced passage, because this new reinforced passage is rectilinear, generally can not stop up, even if there is reinforced latch up phenomenon in the gap location that left hemicone 9 and right hemicone 8 produce after being separated with cylindrical shell 1, cause left expansion link 10 and right expansion link 7 bias to block, and along with gravity constantly alleviates, left expansion link 10 and right expansion link 7 can reset by nature, thereby avoid latch up phenomenon to occur.
