A Z type bucket conveyor mainly consists of motors, reducers, couplings, hydraulic couplers, triangular belts and pulleys, chains and sprockets, inverters and so on. These components are grouped together to form the transmission mechanism of the Z type bucket conveyor. According to the traction form it mainly has belt, chain type 2 kinds, according to the transmission form, it has the belt type, the chain type and the direct connection, etc., it is widely used in the grain, the food, the mine and the chemical industry and so on. So far, through the combination of dynamic calculation simulation and test, it can accurately control the unloading trajectory of materials and realize non-reflux transportation, and through the application of sensor and automatic control technology, the reliability, stability and energy saving effect of transmission mechanism and traction mechanism are also greatly improved.



Z type bucket conveyor adopts the transmission mechanism of the coupling, the transmission frame of the fixing reducer is installed on the tower platform through many foot feet. This multi-pivot mounting type is particularly difficult for the field adjustment of the output shaft of the reducer and the coaxial degree of the spindle of the Z type bucket conveyor. Moreover, excessive balance caused by the bumps of the transmission parts will cause vibration of the support platform, and then affect the nose and barrel, seriously affecting the safe and smooth operation of the hoist. When the coaxial gear motor is used to drive, due to the need to give the coupling position, resulting in the Z type bucket conveyor spindle direction of the installation space. To install a single 18.5 kw transmission mechanism in a cross-section 2.5 mx2.5 M Well frame will need to make a maintenance platform that extends about 1.2 m. Axial reducer refers to its output shaft as a hollow shaft form, and the advantages of using this model are: The absolute coaxial of the spindle of the reducer and bucket elevator greatly reduces the large amount of installation and propagation done to ensure the coaxial degree, saves a lot of space along the direction of the spindle of the lifting head, and avoids the transmission maintenance platform of making the extension. Large-scale equipment using right-angled shaft hollow drive mechanism, can completely solve the problem of excessive foot pivot. The influence of direct connection drive on the speed of lifting head wheel depends entirely on the matching of motor speed and reducer transmission ratio, unlike belt type and chain drive, the transmission ratio can be adjusted by the change of sprocket and pulley. Therefore, in the design stage, it should be for the conveyor volume, belt speed and other conveyor process requirements, select the appropriate reducer speed ratio, in order to avoid future replacement.

Because most of Z type bucket conveyor’s transmission mechanism are arranged in high altitude, compact structure, small footprint, easy installation and maintenance is the most basic requirements, When designing the z type bucket conveyor the selection of reducer, whether it is small gear motor, or large gearbox, hollow shaft output is a selection trend. The transmission of large lifting equipment is generally equipped with hydraulic coupler. In recent years, with the development of electrical and electronic technology, soft Starter, inverter and other electromagnetic control and protection equipment is maturing, they are favored by some projects with the advantages of high efficiency and energy saving, and gradually become a new trend to improve the startup capacity of the motor and prevent equipment overload.
