Detailed Description
In order to better understand the purpose, structure and function of the present invention, a dual-tuyere cab air supply structure of the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the dual-tuyere cab air supply structure of the present invention is installed above a cab, extends in two directions in the cab, is provided with a tuyere above a main and auxiliary cab seat, and can be simultaneously and individually adjusted, and comprises a cab air duct 4, a transition air duct 3, a cab air supply unit 1, a cab air duct 2 and an adjustable tuyere 5, wherein both sides of the cab air duct 4, the cab air supply unit 1 and the cab air duct 2 are provided with mounting brackets 6 for being fixedly connected with a vehicle roof.
Referring to fig. 3 to 6, the passenger compartment air duct 4 supplies air in a manner of side air supply at the end of the passenger compartment, the passenger compartment air duct 4 adopts a bottomless air duct, the lower side is fixedly connected with the built-in top plate and is sealed by the bottom sealing strip 7, the structure ensures that the bottomless air duct of the passenger compartment can be conveniently communicated with the cab air supply unit 1 in a limited space, and the effects of light weight and space saving are achieved while the functions are ensured. The passenger room air duct 4 is L-shaped at both sides of the passenger room end, one end is arranged along both sides of the passenger room, and the other end is arranged transversely along the end and merges at the middle of the passenger room. The middle part of the air duct end plate of the passenger room at the junction is provided with a passenger room air supply opening, the air duct end plate of the passenger room is at a distance from the partition wall of the passenger room, the transition air duct 3 enters the passenger room from the upper part of the partition wall 10 of the passenger room and is connected with the air duct of the passenger room to supply air to the passenger room, and the top of the junction is sealed with the roof of the vehicle body through a sealing strip 8.
Referring to fig. 4, the transition duct 3 includes a soft duct 301, square ducts 302 fixed at both ends of the soft duct, and a mounting plate 303 welded to the ends thereof, and sealing cotton is provided at the outer side of the mounting plate. One end of the air duct connector is connected with the cabin air supply opening in an integrated sealing riveting mode, and the other end of the air duct connector is connected with the cabin air supply unit by bolts.
Referring to fig. 6, the cab air duct 2 is of a Y-shape, one end of the air duct is connected with the cab air supply unit 1 by bolts, the other end of the air duct is divided into two branches, the branches extend to the area above the main and auxiliary driver seats 9 respectively, and a plurality of adjustable air ports 5, generally 3, are connected below the air ports, the number of the adjustable air ports can be increased as required, and the adjustable air ports can be adjusted by 360 degrees respectively as required. The cab air duct 2 is gradually expanded towards the inner cavity of the direction of the vehicle head at the end connected with the cab air supply unit 1, two sides are respectively and hermetically connected with the outer sides of the two branches, the inner sides of the two branches are mutually and hermetically connected, so that a large buffer zone is formed in the middle of the cab air duct, the air from the cab air supply unit 1 is blown into the buffer zone instead of directly blowing into the position of the adjustable air port 5, the diameter of the air duct in the zone is expanded, the air speed is reduced, the air speed steadily flows to the two branches after buffering, the air flow is stable, and the air supply stability is better. The cab air duct 2 is manufactured in a pasting mode, an end mounting plate and the air duct are pasted together, and nuts are embedded in the end mounting plate and are used for bolting.
When the cab air supply structure is assembled, due to errors in manufacturing and assembling, the positions of the cab air supply unit 1 and the cab air supply opening may deviate from the design, an assembly interface between the cab air supply unit 1 and the cab air supply opening cannot completely correspond, a transition air duct is connected between the cab air supply unit 1 and the cab air supply opening, and due to the fact that the transition air duct is a soft air duct, the cab air supply structure is well compatible with the assembly error, the assembly is more flexible, meanwhile, the design precision requirement of the cab air duct is reduced, and more choices can be provided.
