The equipment causes the working environment to be bad due to dust pollution, so that the gear sprocket part of the transmission system is seriously worn. As shown in Fig. 1, the transmission system structure diagram of the existing trough conveyor is shown as the wheel of the active overall sprocket 7. When the tooth wears to a certain extent, the device will not work properly and the sprocket must be replaced. The conventional sprocket of the trough conveyor has a unitary structure, as shown in Fig. 2, and the entire sprocket 7 is required to be removed when replacing. In order to remove the sprocket, the associated part, that is, the drive chain, the coupling, the bearing housing, the bearing 8, etc., must be removed first, and the sprocket can be removed from the transmission shaft 6. The entire overhaul process is labor intensive, costly, and has a long maintenance cycle. Utility model content

为了解决上述技术问题， 本实用新型是这样实现的： 可快速更换 的链轮结构， 它包括轮齿和轮 ， 其中轮齿与轮毂为分体结构， 轮齿 镶嵌在轮毂上。  In order to solve the above technical problems, the present invention is realized as follows: a quick-changeable sprocket structure comprising gear teeth and wheels, wherein the gear teeth and the hub are in a split structure, and the gear teeth are mounted on the hub.

所述的轮齿是通过压紧环、 固定螺栓镶嵌在轮毂上。  The teeth are mounted on the hub by a compression ring and a fixing bolt.

所述的轮齿是多个单齿镶嵌在轮毂上。  The teeth are a plurality of single teeth mounted on the hub.

所述的轮齿是多齿分组镶嵌在轮毂上。  The teeth are multi-toothed inlaid on the hub.

所述的轮齿由两组或两组以上部件组成。  The teeth are composed of two or more sets of components.

本实用新型的优点和效果如下：  The advantages and effects of the utility model are as follows:

本实用新型由于将轮齿与轮毂设计成分体结构， 轮齿镶嵌在轮毂 上， 当轮齿磨损后只需拆开螺栓、 螺母， 而无需更换轮 部分， 便可 很容易的更换轮齿。 这不仅减少了维修工人的劳动强度、 降低了配件 的制造成本， 也大大缩短维修周期， 同时提高了设备的运转率。 轮齿 在纵向截面上具有对称性， 当一侧磨损严重后， 可通过不同的安装方 式改变轮齿的受力面， 增加轮齿一倍的使用寿命。 本实用新型彻底改 变了过去链轮磨损后整体更换的方式。 附图说明 The utility model designs the component body structure of the gear teeth and the wheel hub, and the gear teeth are embedded in the wheel hub On the other hand, when the gear teeth are worn, it is only necessary to disassemble the bolts and nuts, and the gear teeth can be easily replaced without replacing the wheel portion. This not only reduces the labor intensity of the maintenance workers, reduces the manufacturing cost of the accessories, but also greatly shortens the maintenance cycle and increases the operating rate of the equipment. The gear teeth have symmetry in the longitudinal section. When the wear on one side is severe, the force receiving surface of the gear teeth can be changed by different installation methods, and the service life of the gear teeth is doubled. The utility model completely changes the way of overall replacement after the sprocket wears in the past. DRAWINGS
