Working principle and using method

The material carrying mechanism in the feeding device of the stirrer realizes vertical ascending and descending actions along the frame under the driving of the driving mechanism, and the positive rotation of the starting motor drives the hopper and the hopper frame to vertically move upwards; in the vertical ascending stage of the hopper and the hopper frame, when the hopper ascends to a preset position, a hopper extending plate of the hopper is contacted with a cylindrical roller of a first hopper limiting mechanism fixedly arranged on a support, at the moment, the hopper frame continues to ascend, the cylindrical roller of the first hopper limiting mechanism forces the hopper to turn over on the hopper frame, an air spring arranged between the hopper and the hopper frame contracts and then stretches, and when the air spring stretches, the hopper is forced to turn over; when the hopper frame continues to ascend, the first travel switch arranged at the upper end of the frame is touched, the first travel switch sends a signal, the motor is stopped by holding the shaft, and the material carrying mechanism hovers; the outlet end of the hopper is contacted with the second hopper limiting mechanism, and stirred materials in the hopper are poured out from the hopper; stirring materials enter the stirrer through the material receiving mechanism arranged on the support to be stirred.

When the hopper is in a turnover state, the projection on the horizontal plane of the hopper can be lengthened, so that the hopper extension plate can contact the cylindrical roller of the first hopper limiting mechanism; after the stirred materials are poured, the motor rotates reversely to drive the hopper and the hopper frame to move downwards; in the vertical descending process of the hopper and the hopper frame, the cylindrical roller of the second hopper limiting mechanism acts on the hopper extension plate and forces the hopper to reset under the action of the air spring; in the process, the gas spring is shortened and then stretched, when the gas spring is stretched, the reset of the feeding hopper can be promoted, and when the hopper is reset, the gas spring can enable the hopper to be more stable; when the hopper frame just falls above the bearing platform, the second travel switch in the rubber pad is touched, the motor is turned off, and the feeding is completed.
