The auger feeder usually consists of the drive unit, the head section, the intermediate section, the tail section, the head and tail bearings, the inlet and outlet, etc. If the conditions permit, the drive unit is placed at the discharge end, because of the drive unit and the output. When the material is installed in the head section (with the thrust bearing assembly), it is reasonable to make the screw in the pulled state. Each part of the head section, the middle section, and the tail section has several different lengths.

Screw shaft and sling bearing, head, tail shaft

The screw shaft and the suspension bearing, the head and the tail shaft are all connected by the tongue type, and the installation and disassembly do not require axial movement, and the maintenance is convenient. The mandrel is long, has less hanging, and has fewer failure points.

In the overall arrangement of the screw feeder, care should be taken not to place the base and the discharge port at the flange of the casing joint, and the feed port should not be placed above the suspension bearing.

Drive end bearing, tail shaft

The driving end bearing and the tail bearing of the screw feeder are placed outside the trough housing to reduce the influence of dust on the bearing and improve the applicable life of the key parts of the screw feeder.

Sliding bearing

The bearing bush of the spiral feeder sliding bearing has powder metallurgy, nylon and babbitt alloy, which can be selected according to different needs. The flexible arrangement of the inlet and outlet of the screw feeder makes it more adaptable and approved by users.

Hanging bearings

The intermediate suspension bearing of the rotary feeder adopts sliding bearing and has dustproof sealing device. The screw feeder seal is made of nylon or plastic, so the sealing performance is good, the wear resistance is strong, the resistance is small, and the service life is long.

Using a variable diameter structure

The variable diameter structure is adopted to increase the volume of the hanging bearing to avoid contact between the hanging bearing and the material, and the life of the hanging bearing is more than two years.

Using a floating connection

Each transmission part adopts floating connection mode, and the suspension bearing is a universal joint structure, so that the spiral body, the suspension bearing and the tail assembly form an integral spiral floating body, which can freely rotate and avoid with the conveying resistance within a certain range, without jamming or blocking. material.

Head and tail bearing

The head and tail bearing housings are all outside the housing. All bearings are multi-layered and fitted with sealing technology for long bearing life.

The whole machine section

Compared with other conveying equipment, the screw feeder has the advantages of small cross-section size, good sealing performance, stable and reliable operation, medium multi-point loading and unloading, safe operation and easy maintenance.

The arrangement order of the spiral segments of the spiral conveyor is in good accordance with the principle of arranging the spiral segments in the same order according to the length of the spiral segments, and starting from the head in the order of installation.
