Embodiment Construction
[0015] Such as Figure 4 with 5 The connecting structure design of the three-line centered arc transition type hopper cabin inclined bottom plate and inner bottom plate of the present invention mainly includes the connection of the longitudinal inclined bottom plate 1 and the inner bottom plate 2 in the form of a curved arc to make the inner bottom plate 2 and the inclined The intersection of the extension lines of the thickness center line of the bottom plate 1 is located on the arc surface. The inner bottom side longitudinal truss 3 is arranged at the intersection of the inclined bottom plate and the extension line of the inner bottom plate, that is, below the kink line 7 where the inclined bottom plate 1 and the extension surface of the inner bottom plate 2 intersect. And the center line of the inclined bottom plate 1, the inner bottom plate 2, and the inner bottom side stringer 3 are centered by three lines. In a preferred manner, the radius dimension of the arc connecting ...
