[0047] The working process of the present utility model:

[0048] During work, the mixing hopper is sleeved on the lifting fork. The oil pump motor is started. After the hopper is lifted to the set height position by the lifting mechanism, the oil pump motor stops working. The lifted hopper automatically rotates above the feeding equipment through the control of the reducer and the angle encoder. The cylinder is started to automatically open the hopper butterfly valve. After the hopper discharges materials, the cylinder automatically closes the butterfly valve. Then the equipment automatically rotates the hopper to the initial position and descends to the ground. After the operator replaces the hopper with materials, it is ready for the next automatic lifting and feeding process.

[0049] The specific rotation process is as follows: When the hopper reaches the set height, the reducer starts to work, driving the small gear. The small gear meshes with the large gear fixed on the slewing bearing, and the large gear then drives the column, the fork, and the hopper to rotate. It can rotate to any angle. After rotating to the relevant position, the locking cylinder locks the column to complete the automatic rotation action.

[0050] The automatic discharging process: When the hopper reaches the designated position, the cylinder installed on the fork starts to work. The cylinder shaft drives the butterfly valve switch on the hopper to open. After the butterfly valve is opened, the materials fall by gravity from the discharging port to complete the discharging. After the discharging is completed, the cylinder shaft drives the butterfly valve switch on the hopper to close. After the butterfly valve is closed, the hopper rotates to the initial position when rising and descends to the ground. The operator replaces the hopper and prepares for the next lifting and feeding.

The utility model can be widely used in industries such as pharmaceuticals, chemicals, and food.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.
