This invention refers to a rubber conveyer belt, especially a heat resistant conveyer belt with side walls.
Conventionally, a heat resistant conveyer belt with side walls includes a base belt, cleats positioned on the base belt and skirt-boards positioned at two sides of the cleats. The cleats comprise a base and an incline board on the base. Because this kind of conveyer belt is made of rubber, its rigidity is lower. Its cleats and skirt-boards are only fixed on the base belt by means of secondary sulfuration, so that the belt is lack of heat resistant and aging resistant and so on. It results that they often get loose from the base belt, which decreases the life time of the conveyer belt and increases its cost.
This invention aims at solving such a prior technical problem that cleats and skirt-boards easily get loose from a base belt and discloses a heat resistant conveyer belt with side walls whose cleats and skirt-boards fixed on the base belt firmly.
In order to solve the technical problem said above, the heat resistant conveyer belt with side walls according to the invention comprises a base belt and cleats positioned on the base belt, wherein metal frameworks are embedded in said cleats and the cleats are fixed on said base belt through fasteners.
Furthermore, according to this invention, the conveyor belt also comprises skirt-boards positioned at two sides of said cleats and fixed on said base belt through fasteners, and metal sheet is embedded in the base of said skirt-boards.
Still further, for preventing the cleats from breaking, according to this invention, the cross sectioned shape of the metal frameworks fits that one of the cleats.
Still further, according to this invention, the fasteners are bolts.
This invention has following advantages:
The cleats and the skirt-boards are respectively embedded with metal frameworks and sheet within, so that they can be fixed on the base belt through fasteners, thereby preventing themselves from getting loose from the base belt under high temperature, increasing the life time of the conveyor belt and decreasing its cost.
