The screw shaft of the spiral feeder is embedded with the tongue type, which is connected with the hanging bearing, the head and the tail shaft.
The installation and dismantling do not need the axial movement, and the maintenance is convenient. The core axis is long,
the hanger is few, and the fault point is few.
The spiral feeder adopts the variable diameter structure to increase the volume of the hanging bearing and avoid contact with the material of the bearing.
The life of the hanging bearing can be over two years. The head and tail bearing seats are all in the shell, and all bearings are sealed
with multi-layer sealing and sealing technology, and the bearing life is long.
All parts of the screw feeder are connected by floating connection, and the hanging bearing is a universal joint structure, so that the spiral body,
the hanging bearing and the tail assembly form an integral floating body. Within a certain range,
it can move freely with the transportation resistance and avoid sticking and blocking.
Compared with other conveying equipments, the screw feeder has the advantages of small section size, good sealing performance,
smooth and reliable operation, multiple loading and unloading in the middle, safe operation and simple maintenance.
