Description
Technical field
The invention belongs to bituminous mixture and stir equipment technology field of transport, be specifically related to the component that bituminous mixture stirs haulage device.
Technical background
The bituminous mixture mixed first through fixing malaxation device mix, then will be transported to construction plant with delivery vehicle and use by pavement construction bituminous mixture used usually.During transportation, the temperature of bituminous mixture can decline, uneven, and also there will be segregation phenomenon, these all can affect asphalt roads construction quality simultaneously.For the bituminous mixture that mobility is larger, as casting type asphaltic mixture, this point can show very serious.Therefore, usually to stir it in casting type asphaltic mixture transportation, prevent segregation; To heat, to ensure that bituminous mixture has normal serviceability temperature simultaneously.
The patent No. is 200320115371.1, utility model name is called the Chinese utility model patent of " pouring asphalt concrete agitator ", disclose a kind of casting type asphaltic mixture and stir haulage device, this equipment can stir the bituminous mixture of large fluidity and heat in transportation.
In order to prevent larger material from entering damage equipment in agitated kettle, usually screen pack is set at the charging aperture place of feed arrangement.Existing casting type asphaltic mixture mixing plant charging aperture screen pack adopts bolt to be connected and fixed simply at the wall of charging aperture.This connecting mode is simple, but in use pitch inevitably enters the gap between screen pack and charging aperture, also can penetrate into the gap of thread connector, when the component in agitated kettle break down, cool after keep in repair time, due to the adhesion of the pitch after solidifying, bolt is caused to be difficult to turn, screen pack almost cannot be dismantled, and can only adopt and screen pack cutting be removed, on again being welded by screen pack after having overhauled again, wasting manpower and material resources, improves maintenance cost.
The patent No. is 200320115371.1, utility model name is called the Chinese utility model patent of " pouring asphalt concrete agitator ", this stirring haulage device covers the smoke vent opening arranging heater, but the wind that this smoke vent opening heads on when only preventing equipment to run enters combustion chamber from smoke vent opening, do not prevent the wind that other direction is come.In use often occur that wind blows into combustion chamber from smoke vent opening, causes fray-out of flame.When loading bituminous mixture, inevitably some asphalt materials are spread across charging aperture surrounding.This stirring haulage device does not control the asphalt material being spread across surrounding, and in use these asphalt materials are difficult to collect, and cause waste, and affect the outward appearance of equipment.
Summary of the invention
Technical problem to be solved by this invention is the shortcoming overcoming above-mentioned patent, provide a kind of reasonable in design, maintenance cost is low, the large fluidity bituminous mixture that works well stirs haulage device upper cover.
Solving the problems of the technologies described above adopted technical scheme is: be processed with charging aperture at the middle part of upper cover plate, filter screen is provided with above charging aperture, charging aperture door leaf is provided with above filter screen, smoke vent opening is processed with on front side of upper cover plate, smoke vent opening is provided with connected with smoke vent opening left plate by the side of smoke vent opening front side board and smoke vent opening back side panel, opposite side connects with smoke vent opening right plate the smoke exhaust pipe formed, smoke exhaust pipe upper end is provided with exhaust hood, is processed with surrounding not confined bed chute at the edge of upper cover plate upper surface; The surrounding of filter screen is at least provided with 3 locating pieces connected with upper cover plate with connector; The rear wall of exhaust hood of the present invention, left side wall, right side wall are respectively lower than the upper end of smoke vent opening back side panel, smoke vent opening left plate, smoke vent opening right plate, and front side wall and the smoke vent opening front side board upper end of exhaust hood combine as a whole.
Connector of the present invention is: gripper shoe is welded on upper cover plate, and each locating piece pressing plate and Bolt Connection fixed installation are on the supporting plate.
Connector of the present invention is: locating piece, on upper cover plate, is fixed on the supporting plate with U bolt by gripper shoe weld connection.
Distance d between the lower end of the rear wall of exhaust hood of the present invention, left side wall, right side wall and smoke exhaust pipe upper end is 10 ~ 50mm.
The present invention adopt the coupling head pressing plate of screen pack surrounding or U bolt fixing on cover, when device interior component break down, be easy to screen pack to remove, overhaul in maintainer's access arrangement; Left and right, the back side panel of smoke exhaust pipe upper cover of the present invention extend to below smoke exhaust pipe upper end, efficiently solve large fluidity bituminous mixture and stir haulage device external wind-fall filling in the process of moving by the technical problem of the flame blow-off of burner; Be processed with guiding gutter at the edge of upper cover, solve when loading bituminous mixture the technical problem that upper cover pollutes.The present invention have reasonable in design, work well, the advantage such as maintenance cost is low, can stir on haulage device at large fluidity bituminous mixture and use.
