Description

A kind of screw conveyor

Technical field

The utility model belongs to material transfer equipment technical field, and in particular to a kind of screw conveyor.

Background technology

Screw conveyor is mainly for delivery of powdery, graininess and small lump material.In use, screw conveyor passes through rotation Material from the feed inlet of lower to the discharge port passage positioned at higher position, and is finally made material from higher by the helical blade turned The discharge port at place enters in load wagon.

At present, existing screw conveyor has the following disadvantages：

(1) material less than conveyer screw pitch itself can only be conveyed, can not be conveyed for bulk materials, the volume mistake of material Conference is stuck by spiral, it is impossible to run well；

(2) since relatively long distance conveying intermediate demand installation drop-hanger bearing is so as to easily cause obstruction, transfer efficiency is caused Lowly, it is poor to adapt to material；

(3) material leakage accident easily occurs in transmission process, end bearing blocks before causing conveyer, easily damages It is bad.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without creative efforts All other embodiments obtained shall fall within the protection scope of the present invention.

In the description of the utility model, it is to be understood that term " on ", " under ", "front", "rear", "left", "right", The orientation or position relationship of the instructions such as " vertical ", " level ", " top ", " bottom ", " interior ", " outer " be based on orientation shown in the drawings or Position relationship is for only for ease of description the utility model and simplifies description rather than instruction or imply signified device or member Part must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model. In the description of the utility model, unless otherwise indicated, " multiple " are meant that two or more.

Refering to Fig. 1 and Fig. 2, the screw conveyor in one embodiment of the utility model including filling pocket 1, feed hopper 2, twists Imperial main shaft 3, packing auger blade 4, casing 7 and dump skip 8.Wherein, packing auger blade 4 is arranged on auger main shaft 3, and auger main shaft 3 On the bottom plate at 7 both ends of casing.The front end of casing 7 is equipped with feed hopper 2, and 2 left side of feed hopper is equipped with filling pocket 1, casing 7 Rear end is equipped with dump skip 8.Hopper slot 6 is equipped between casing 7 and auger main shaft 3, the hopper slot 6 is fixed on casing 7, so Bulk materials can be conveyed in the top of spiral by the frictional force between packing auger blade 4.

Refering to Fig. 1 and Fig. 3, as another preferred embodiment of the utility model, drop-hanger bearing is removed, and will be traditional Auger main shaft is changed to overstriking type auger main shaft 3, and auger main shaft 3 is made to form a complete conveyor screw, and centre is not spaced, carries High transfer efficiency.

On the basis of above-described embodiment several feed well support plates 5, feed well support plate 5 are equipped in 6 bottom of hopper slot It is mutually ratcheting with hopper slot 6, casing 7 respectively；2 rear end of feed hopper be equipped with feed hopper support plate, feed hopper support plate respectively with hopper Slot 6, charging bottom sheet are mutually ratcheting, ensure that screw conveyor to the enabling capabilities of bulk materials, alleviates the support of auger main shaft 3 Burden extends the service life of screw conveyor.

Refering to Fig. 1 and Fig. 4, the rear end of auger main shaft 3 is mounted on by bearing 11 in the bearings plate of dump skip 8, preceding End is mounted on by wearing plate 9 on the bottom plate of feed hopper 2, which is fixed by 10 spiral of limiting plate.Wherein, this is wear-resisting Plate 9 is preferably the nose circle face of static friction.Auger main shaft 3 is all fixed in traditional screw conveyor rear and front end by bearing, due to Material leakage accident can occur often for the material of conveying, be deposited on the bearing of screw conveyor front end, made due to gravity It is easily blocked into preceding end bearing, it is difficult to clear up and be easily damaged.The utility model replaces preceding end bearing using wearing plate 9, Without worrying blocking accident, solve sealing problem, decrease the failure rate of equipment.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modifications, equivalent replacements and improvements are made should be included in the utility model Protection domain within.
