Tray assembly and feeding device

Abstract

The utility model provides a tray assembly and a feeding device, and relates to the technical field of monocrystalline silicon preparation equipment. The tray assembly comprises a quartz cone, a connecting piece and a fixing piece; the quartz cone comprises a first cone and a second cone; the first cone is arranged at one end of the second cone; a first accommodating cavity is formed in the first cone, and a second accommodating cavity communicated with the first accommodating cavity is formed in the second cone; the connecting piece comprises a connecting part and a fixing part which are connected; the fixing part is fixed in the second containing cavity, one part of the connecting part is arranged in the second containing cavity, and the other part of the connecting part is arranged in the first containing cavity; the connecting part is used for being connected with a lifting rod arranged in the first containing cavity in a penetrating mode. The fixing piece abuts against the end, away from the second cone, of the first cone. The fixing piece is used for connecting the lifting rod. The feeding device comprises a tray assembly. According to the tray assembly, the use cost can be reduced, and the quartz cone is prevented from falling off from the lifting rod.
