Abstract
The utility model belongs to the technical field of conveyors, and discloses a belt conveyor. The belt conveyor is mainly characterized by comprising a power mechanism, a speed reducing mechanism, a roller, a conveying belt, a carrier roller and a frame body, the carrier roller comprises a carrier roller shaft and a carrier roller shell connected with the carrier roller shaft through a bearing, the carrier roller shell comprises blocking off faces located at the two ends and a roller body side face, the side face of the carrier roller shell is a curved surface obtained by rotating the axial symmetry curve of the carrier roller shaft along the straight line where the carrier roller is located by a round, and the carrier roller shaft is fixed to the frame body. Thus, in the material conveying process, the cross section of the conveying belt is lower in the middle and higher on the two sides, material is prevented from falling off, the diameter of the carrier roller shaft further can be increased, overall strength of the carrier roller is improved, the rotating number of the bearing is reduced, the service life of the bearing is prolonged, conveying amount of materials is increased, work efficiency is improved, no edge exists on the surface of the carrier roller, abrasion to the belt is small, and the service life of the belt is prolonged.
Description
Technical field
The utility model belongs to the conveyer technical field, relates to concretely band conveyor.
Background technology
In mine, the occasion such as harbour, factory, mostly by material conveyor, carry out convey materials, the life-span length of conveyer is not only determining the mass transport cost, but also is determining the efficiency of mass transport.The conveyer used at present comprises actuating unit, speed reduction gearing, cylinder, load-transfer device, carrying roller and support body, its carrying roller comprises the oblique carrying roller that is positioned at both sides and is positioned at middle flat idler, support body is to be positioned at the edge column support body of both sides and to be positioned at middle central post support body, there is following defect in this conveyer: one, there are corner angle in oblique carrying roller and flat idler junction, in the belt operational process, to the belt serious wear, greatly reduce the life-span of belt; Its two, support body quantity is many, maintenance and safeguard inconvenient; Its three, idler diameter is little, rotates the number of turns many, bearing life is low; Its four, the carrying roller withstanding corrosion is poor, service life is low.
The utility model content
The technical matters that the utility model solves just is to provide a kind of belt and bearing long service life, maintenance maintenance band conveyor easily.
For solving the problems of the technologies described above, the technical scheme the utility model proposes is: comprise actuating unit, speed reduction gearing, cylinder, load-transfer device, carrying roller and support body, described carrying roller comprises roller carrier shaft and the carrying roller housing be connected with this roller carrier shaft by bearing, described carrying roller housing comprises that the shutoff face and the roll body side that are positioned at two ends form, the side of described carrying roller housing is for the curve about the axial symmetry of described roller carrier shaft around the described roller carrier shaft place straight line gained curved surface that rotates a circle, and described roller carrier shaft is fixed on described support body.
Its additional technical feature is:
Described curve is hyperbola;
Described curve is parabola;
On the roll body side of described carrying roller housing, be arranged at intervals with along the axial dashpot of carrying roller.
The band conveyor that the utility model provides, compared with the existing technology have the following advantages: one, owing to comprising actuating unit, speed reduction gearing, cylinder, load-transfer device, carrying roller and support body, described carrying roller comprises roller carrier shaft and the carrying roller housing be connected with this roller carrier shaft by bearing, described carrying roller housing comprises that the shutoff face and the roll body side that are positioned at two ends form, the side of described carrying roller housing for the curve about the axial symmetry of described roller carrier shaft around the described roller carrier shaft place straight line gained curved surface that rotates a circle, described roller carrier shaft is fixed on described support body, like this, both guaranteed that the load-transfer device cross section presented middle low both sides high, prevent that material from coming off, and can also improve the diameter of roller carrier shaft, thereby improve the bulk strength of carrying roller, reduced the rotation number of turns of bearing, extended the service life of bearing, increased the upwards of movement of material, improved work efficiency, and there are not corner angle in the carrying roller surface, little to the belt wearing and tearing, extended belt life, its two, because described curve is hyperbola or parabola, not only be convenient to processing, and each point is stressed evenly, has further extended its service life, its three, owing to being arranged at intervals with along the axial dashpot of carrying roller on the roll body side at described carrying roller housing, when material drops on load-transfer device, play buffer action.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model band conveyor;
The section-drawing that Fig. 2 is carrying roller;
Fig. 3 is the structural representation with the carrying roller of dashpot.
The specific embodiment
The structure of band conveyor the utility model proposed below in conjunction with accompanying drawing is described further.
As shown in Figure 1, Figure 2 and Figure 3, be the structural representation of band conveyor.Its structure comprises actuating unit 1, speed reduction gearing 2, cylinder 3, load-transfer device 4, carrying roller 5 and support body 6, carrying roller 5 comprises roller carrier shaft 7 and the carrying roller housing 8 be connected with this roller carrier shaft 7 by bearing 9, carrying roller housing 8 comprises that the shutoff face 81 and the roll body side 82 that are positioned at two ends form, the curve 83 that the roll body side 82 of carrying roller housing 8 is the axial symmetry about roller carrier shaft 7 is around the roller carrier shaft 7 place straight lines gained curved surface that rotates a circle, and roller carrier shaft 7 is fixed on support body 6.
Like this, both guaranteed that the load-transfer device cross section presented middle low both sides high, prevented that material from coming off, and can also improve the diameter of roller carrier shaft 7, thereby improve the bulk strength of carrying roller, reduced the rotation number of turns of bearing 9, extended the service life of bearing 9; Increased the upwards of movement of material, improved work efficiency, and there are not corner angle in the carrying roller surface, little to the belt wearing and tearing, extended belt life.
Be arranged at intervals with on the roll body side 82 of carrying roller housing 8 along the axial dashpot 10 of carrying roller, when material drops on load-transfer device, play buffer action.
Protection domain of the present utility model not only is confined to above-described embodiment, as long as structure is identical with the utility model band conveyor structure, just drops on the scope of the utility model protection.
