The utility model relates to a Z type bucket elevator used for lifting and feeding, which can automatically complete feeding, lifting and controlling actions without personnel assistance and has the advantages of safety and hygiene, simplicity, convenience and high efficiency. It is mainly composed of feeding motor, body, elevator bucket, main drive wheel, slave wheel, steering wheel and material bucket. The machine body of the hoist is z shaped, the feeding port is located at the upper end of the machine body, the upper end of the rear end of the machine body is provided with a material hopper and the lower end of the material hopper is provided with a vibrating feeder. A lift bucket on a transfer chain connecting the outlet of a machine hopper. The upper and lower ends of the frame are provided with the main driving wheel driven by the feeding motor and the frame parallel to the main driving wheel is provided with the regulating wheel tightness adjusting device. The slave and steering wheel are located at the corner of the rack and the main and slave wheels drives the transmission chain. The regulating wheel elastic regulating device is composed of regulating wheel, regulating bolt,slide and shaft. The slide is equipped with the corresponding body sliding. The regulating wheel is connected with the slide through the shaft and the body and the slide are moved of fixed through the regulating bolt. When it is necessary to adjust the tightness of the transmission chain, we can simply adjust the control wheel on the end transfer chain. While adjusting, screw the adjusting bolt and adjust the distance between the slide and the corresponding body. The middle of both ends of the elevator bucket is provided with the shaft hole of the elevator bucket and connected with the fixed pin shaft of the elevator bucket on the transmission chain. A bucket balance pin is arranged on the transmission chain at the front end of the bucket fixing pin and is located on the end of the last two sides of the corresponding bucket whose slide section is semicircle or triangle.

In operation, the materials to be packed are put into the material bucket at the upper end of the vibrating feeder of Z type bucket elevator at the same time, the feeder motor drives the main drive wheel to drive the slave wheel, regulating wheel and steering wheel, so that the transmission chain on it runs counterclockwise and upward, driving the hoisting bucket between the two transmission chains to move from bottom to up. When the conveyor chain moves horizontally, the upper plane of the each elevator bucket in this segment is parallel to the conveyor chain and the elevator bucket balance pin card is held at both ends of the rear side of the corresponding elevator bucket. The front and rear edges of the adjacent elevator bucket are staggered to form a plane that passes through the lower end of the outlet of the material bucket. The vibrating feeder vibrates to automatically drop the material from the outlet to each elevator bucket on the transmission chain. Each elevator bucket carries the material forward, when the transmission chain moves vertically upward, the bottom center moves downward under the action of gravity and the upper plane is perpendicular to the transmission chain. The bucket balance pin card is held both sides of the lower end of the corresponding bucket. The top of the lifting and turning pin card is on the corresponding lifting bucket turning and turning position, so that the lifting bucket reverses with the moving wheel to pour materials from the lifting bucket into the feeding port, complete the material transportation, repeat the operation in turn and complete the whole material transportation process of Z type bucket elevator.
