The uneven distribution causes deviations in the force applied to the chains at both ends. This will not only affect the overall operation of the elevator, but also affect the service life of the chain. [Contents of the utility model]

[0034] Working process of this utility model:

[0035] The utility model discloses an adjustable uniform feeding hoist tail mechanism. During the working process, during the operation of the hoist, the material enters the feed casing 1 through the feed port 2, and the material is accumulated in the distribution chamber 19 at the upper part of the feed casing 1. Then the motor 61 drives the shaft 4 to rotate through the coupling 63, and the material in the distribution chamber 19 is evenly transported to the lower space of the feed casing 1, and finally output from the discharge port 3. The material flows out through the guide inclined plate 16, and then flows into the hopper, so that the material is evenly distributed inside the hopper. At the same time, the feed amount at the tail of the hoist can be dynamically adjusted by changing the motor speed.

[0036] When the material distribution chamber 19 needs to be cleaned, the electromagnet 73 works to attract the attracted body 74 to move backward, and the attracted body 74 drives the transmission shaft 71 to move backward while stretching the spring 72. The transmission shaft 71 drives the rapping head 76 to move counterclockwise through the cooperation of the limit groove 77 and the rotating arm 75. Then the electromagnet 73 is powered off, and the attracted body 74 quickly drives the transmission shaft 71 to move forward under the action of the spring 72. The transmission shaft 71 drives the rapping head 76 to move clockwise through the cooperation of the limit groove 77 and the rotating arm 75 and knocks the rapping transmission plate 111. The rapping transmission plate 111 drives the rapping base plate 18 to vibrate, thereby cleaning the material attached to the rapping base plate 18.
