(3) on-spot operative employee can forget sometimes and carry out the pressure release and directly dock head tank and equipment to the head tank in the operation process, opens the back when the butterfly valve, and the raw materials can be discharged fast under the effect of jar internal pressure and is full of equipment and cause the incident.

The significance of solving the technical problems is as follows: the technical problem is solved, the production pin rate and the reliability of the metering filling machine for the neodymium iron boron rare earth permanent magnet material can be improved, meanwhile, the manual labor intensity is conveniently and quickly reduced when the charging bucket is in butt joint with equipment, and the safety problems that the raw material is discharged due to the fact that the rubber tube is broken and the raw material tank is not decompressed are solved.

Disclosure of Invention

The invention is realized in this way, a metering and filling method for Nd-Fe-B rare earth permanent magnet material, which comprises the following steps:

step one, feeding: after the raw material tank is installed on the field rack, a field operator operates the floating connecting device to be in fast-assembly connection with the raw material tank through a second clamp, and in the process of fast-assembly connection, an interface of the floating connecting device can move in three spatial directions; after the connection is finished, opening a pneumatic butterfly valve, normally adding the raw material in the raw material tank into a transition material tank of the weighing type material level detection device, and closing the butterfly valve when the preset weight range is reached through comparing the pressure value of the sensor with the set parameters in the first weighing instrument by the transition material tank;

step two, weighing: in the coarse feeding process of the first stage, the vibrating feeder swinging device is driven by a driving cylinder, rotates by taking a roller bearing as a rotation center to increase the inclination angle of a trough and the distance between the vibrating feeder swinging device and an outlet at the lower part of the material level detection device, and simultaneously works in a coarse feeding voltage state, the feeding amount of the vibrating feeder swinging device is maximum at the moment, so that the coarse feeding requirement of the stage is met;
