Under certain mine scenes, particularly in large-scale mines in Australia and south America, for large-size, large-specific gravity and sharp-edged copper ores, iron ores and rubber conveying belts made of conventional natural rubber materials, the service life of the conventional rubber conveying belts can only be met after the rubber conveying belts are worn by less than or equal to 90mm3 even if the strength reaches 26mpa, and all the well-known enterprises can not break through the performance limit of the conventional rubber conveying belts all the time, and the development of the ultra-high-strength and ultra-wear-resistant rubber conveying belts is imperative in the face of the increasingly-improved requirements of high-end customers.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a wear-resisting conveyer belt aims at solving among the prior art problem that the conveyer belt wearability is poor, life is low.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a wear-resisting conveyer belt, includes outer polyurethane rubber layer, cohesion polyurethane rubber layer and sets up at least one deck fibrous layer between outer polyurethane rubber layer and the cohesion polyurethane rubber layer which characterized in that: an upper transition layer is arranged between the fiber layer and the outer polyurethane rubber layer, and a lower transition layer is arranged between the fiber layer and the inner polyurethane rubber layer.
The utility model discloses a further technical scheme does, go up the transition layer and be polyurethane and natural gum blend transition layer.
The utility model discloses a further technical scheme does, lower transition layer is polyurethane and natural gum blend transition layer.
The further technical proposal of the utility model is that the fiber layer is a canvas layer.
The further technical scheme of the utility model does, the canvas layer sets up the three-layer.
The further technical scheme of the utility model does, adjacent two-layer all be equipped with the core between the canvas layer, between canvas layer and the last transition layer and between canvas layer and the lower transition layer and glue the layer.
The beneficial effects of the utility model are that:
the utility model discloses promote present conventional rubber conveyer belt rubber strength and wear resistance more than doubly, make the conveyer belt can bear the big proportion iron ore of jumbo size, copper mine lump material conveyer belt, great improvement the wearability and the intensity of conveyer belt, prolonged the life of conveyer belt.

In the figure: 1. an outer polyurethane rubber layer; 2. an upper transition layer; 3. a fibrous layer; 4. a core glue layer; 5. a lower transition layer; 6. an inner polyurethane rubber layer.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1, the working surface of the wear-resistant conveyor belt adopts a mixing type outer polyurethane rubber layer 1, the non-working surface adopts a mixing type inner polyurethane rubber layer 6, and at least one fiber layer 3 is arranged between the outer polyurethane rubber layer 1 and the inner polyurethane rubber layer 6, an upper transition layer 2 is arranged between the fiber layer 3 and the outer polyurethane rubber layer 1, and a lower transition layer 5 is arranged between the fiber layer 3 and the inner polyurethane rubber layer 6.
In the specific embodiment, the rubber strength of the conveyer belt is more than 35Mpa, the DIN abrasion is less than or equal to 50mm, the rubber strength and the wear resistance of the conventional rubber conveyer belt are improved by more than 1 time, the conveyer belt can bear large-size large-specific-gravity iron ore and copper ore lump material conveyer belts, the wear resistance and the strength of the conveyer belt are greatly improved, and the service life of the conveyer belt is prolonged.
In another embodiment of the utility model, the upper transition layer 2 is a polyurethane and natural rubber blending transition layer, which improves the adhesive force between the upper transition layer and the outer polyurethane rubber layer 1, and the adhesive force reaches 15N/mm.
Specifically, the lower transition layer 5 is a polyurethane and natural rubber blended transition layer, and the adhesive force of the lower transition layer 5 and the inner polyurethane rubber layer 6 is improved.
Specifically, the fiber layer 3 is a canvas layer, and the number of layers of the canvas layer can be adjusted according to the actually required strength of the conveying belt.
In this embodiment, the canvas layers are provided in three layers.
Specifically, core rubber layers 4 are arranged between two adjacent canvas layers, between the canvas layers and the upper transition layer 2, and between the canvas layers and the lower transition layer 5.
