Description

Conveyer

Technical field:

The utility model relates to a kind of industrial feedway, specifically a kind of conveyer.

Background technology:

The at present suitable conveying powdered and graininess of conveyer, little lump material are as coal dust, carbon black, soda ash, ground rubber, zinc oxide, calcium carbonate, cement, chemical fertilizer, paper pulp, cereal, flour, feed and nut coal etc.But simple in structure, sealing property is bad, the phenomenon that stirs up a cloud of dust often occurs, efficient is not high, maintenance is inconvenient.

Summary of the invention:

Goal of the invention of the present utility model is to overcome the prior art deficiency, provides a kind of employing that head, tail bearing are moved to outside the housing, and is provided with the exclusion seal device, and sealing property is reasonable, the conveyer of stopping to stir up a cloud of dust.

The purpose of this utility model is finished by the following technical solutions:

A kind of conveyer, comprise motor, motor base, the helicallobe axle, casing, the exclusion seal device, middle part bearing suspension device, described motor and motor base are affixed, also comprise head bearings sealing arrangement and tail bearing sealing arrangement, described head bearings sealing arrangement comprises the head shaft bearing, the head axis of guide, in the described head shaft bearing head bearings is housed, this head bearings inner ring is socketed on head axis of guide front end, this head axis of guide front end is connected with the mouth of motor, the head bearings gland is equipped with at the two ends of described head shaft bearing respectively, and the head bearings gland front end that is positioned at left end is provided with the head circular nut; Described tail bearing sealing arrangement comprises tail bearing seat, the afterbody axis of guide, in the described tail bearing seat tail bearing is housed, this tail bearing inner ring is socketed on afterbody axis of guide rear end, the front end of this afterbody axis of guide is connected with the helicallobe axle, the afterbody circular nut is equipped with in its rear end, and the right-hand member of described tail bearing seat is provided with the tail bearing gland.

Adopt technique scheme, compared with prior art, the utility model has the advantages that:

This conveyer moves to head, tail bearing sealing arrangement outside the housing, and its bearing adopts and rolls, and pulley bearings exchanges structure, and the dirt sealing arrangement of setting up defences, sealing member is with the nylon plastics, thereby its good airproof performance, and resistance to abrasion is strong, and resistance is little, total noise of centrifuge is low, and operating maintenance is convenient, long service life.
