Description
CERTIFICATE OF VERIFICATION 1I, ZHANG, Qunfeng Of China Patent Agent (H.K.) Ltd. state that the attached document is a true and complete translation to the best of my knowledge of International Patent Application No, PCT/CN2007/001932. Dated this day of e 2008 Signature of Translator FPME07140034P Quickly Replaceable Chain Wheel Structure Technical Field The present utility model relates to a driving chain wheel of a chute conveyor as a conveying apparatus adapted to convey bulk solid material at a high temperature and heavy load, particularly to an easily replaceable chain wheel structure of a chute conveyor Background Art A chute conveyor is an apparatus for conveying alumina clinker in a burning workshop in an alumina factory. Because of deterioration of working environment due to dust contamination, a wheel tooth portion of a driving chain wheel in a transmission system of the apparatus wears seriously. Fig. I is a schematic view of a transmission system of a prior art chute conveyor. When the wheel tooth of the driving unitary chain wheel 7 wears to a certain degree, the apparatus will not operation normally, whereupon a chain wheel must be changed. The driving chain wheel of a conventional chute conveyor is a unitary structure, as shown in Fig.2. the unitary chain wheel 7 needs to be detached upon replacement. The first thing to do in detaching the chain wheel is to detach parts related to the chain wheel, such as a transmission chain, a coupling, a bearing seat and a bearing 8, and then the chain wheel can be detached from a transmission shaft 6. The whole repair process requires intensive labor, high costs and a long repair cycle. Summary of the Utility Model A technical problem the present utility model intends to solve is to provide a novel quickly replaceable chain wheel structure, to solve the technical problem such as intensive labor, high costs and a long repair cycle during the whole repair process caused by, first of all, detaching parts related to the chain wheel such as a 1 transmission chain, a coupling, a bearing seat and a bearing during the repair of the chain wheel of the chute conveyor. To solve the aforesaid technical problem, the present utility model is fulfilled as follows: a quickly replaceable chain wheel structure, comprising a wheel tooth and a hub, characterized in that the wheel tooth and the hub are separate and the wheel tooth is embedded on the hub. Said wheel tooth is embedded on the hub via a pressing ring and a fixing bolt. Said wheel tooth is a plurality of individual teeth embedded on the hub. Said wheel tooth is multiple teeth embedded on the hub in groups. Said wheel tooth comprises two or more groups of parts. The advantages and effects of the present utility model are as follows: According to the present utility model, since the wheel tooth and the hub are designed as separate parts and the wheel tooth is embedded on the hub, the wheel tooth can be very easily replaced by only detaching the bolt and the nut, needless to replace the hub portion, when the wheel tooth on the hub wears. This not only reduces labor intensity of repairers but also cuts the manufacturing costs of the accessories, substantially shortens the repair cycle and meanwhile improves the operation rate of the apparatus. The wheel tooth is symmetrical in the longitudinal cross section. When one side thereof wears seriously, a force receiving surface of the wheel tooth 3 is changed by different mounting modes to increase the working life of the wheel tooth by one time. The present utility model thoroughly alters the mode of replacing the whole of the chain wheel when the chain wheel wears in the past. Brief Description of Drawings Fig. I is a schematic view of a transmission system of a prior art chute conveyor; Fig.2 is a schematic view of a unitarily constructed chain wheel in the prior art, and Fig.3 is a schematic view of a separately constructed chain wheel according to the present utility model. In the figures, the reference numeral 1 denotes bolt, 2 nut, 3 wheel tooth, 4 pressing ring, 5 hub, 6 transmission shaft, 7 unitary chain wheel, and 8 bearing. 2 Modes of Carrying out the Utility Model The present utility model will be further described in detail with reference to Fig.3 and the scope of protection of the present utility model is not limited to the embodiments. As shown in Fig.3, a chain wheel of the chute conveyor is a structure formed by combining separate parts. The chain wheel is specifically constructed as follows: it comprises a wheel tooth 3 and a hub 5 which are separate parts, wherein the wheel tooth 3 is embedded on the hub 5 via a pressing ring 4, a bolt 1 and a nut 2 for fixation. The wheel tooth 3 can be a plurality of individual teeth embedded on the hub 5 or multiple teeth embedded on the hub 5 in groups. Said wheel tooth 3 can comprise two or more groups of parts. When the wheel tooth 3 needs repairing and replacing, the parts of the wheel tooth 3 can be very easily detached only by detaching the bolt I and the nut 2. The wheel tooth 3 is symmetrical in the longitudinal cross section. When one side thereof wears seriously, a force receiving surface of the wheel tooth 3 is changed by different mounting modes to increase the working life of the wheel tooth by one time. 3
