They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the protection content of the present invention.
[0024] like Figure 1-Figure 5 As shown, a carriage of a push dump semi-trailer includes a frame 1 and a silo 2. The silo 2 is fixedly connected to the frame 1. The frame 1 includes a left beam 3 and a right beam 4. The left beam 3 and the right beam 4 are variable-section beams with a lower front and a higher rear. The left and right beams each include an upper wing plate 5, a middle vertical plate 7, and a lower wing plate 6. A plurality of cross beams 8 are fixed in the middle and on both sides of the left beam 3 and the right beam 4 to form a skeleton structure.
[0025] The cross-section of the silo 2 is U-shaped, with the material inlet at the top and the material outlet at the rear. The bottom of the silo 2 is a frame structure 9, on which a rubber conveyor belt 10 for unloading can be placed. The left and right sides of the silo 2 are provided with side wall panels 11, and an oblique side panel 12 is provided above the side wall panel 11 to prevent the material from piling up at the edge when loaded. A plurality of vertical support ribs 13 and horizontal support ribs 14 are provided in the middle of the side wall panel 11 to improve the overall structural strength.
[0026] In some embodiments, as Figure 4 、 Figure 5As shown, the frame structure 9 includes a left beam 15 and a right beam 16. The middle of the left beam 15 and the right beam 16 are connected by a plurality of horizontal scales 17. The horizontal scales 17 are provided with a plurality of vertical scales 18. The left beam 15 and the right beam 16 of the frame structure 9 are respectively fixedly connected to the cross beam 8 on the frame 1. Figure 2 As shown, there is no support between the frame 1 and the silo 2, which is used for the operation of the rubber conveyor belt 10.
[0027] In some embodiments, the longitudinal scale 18 can be made of a rectangular tube, which is more convenient to process.
[0028] In some embodiments, as Figure 5 As shown, the left beam 15 and the right beam 16 are bent plates, and a plurality of vertical reinforcing ribs 20 are provided along their length direction. The reinforcing ribs 20 are connected to the horizontal beam 17, and the overall structural strength is high.
[0029] In some embodiments, as Figure 3 As shown, lining plates 19 are welded to the bottom of the lower wing plate 6 at the front end of the frame 1 and the side of the middle vertical plate 7 to further improve the strength of the structure.
[0030] In some embodiments, as Figure 2 As shown, the side wall panel 11 comprises two bent plates, upper and lower, with the middle seam being crimped. This bending and crimping process not only improves the side wall panel 11's resistance to deformation, preventing deformation and flashing at the seam, which could lead to leakage of fine powder, but also reduces weld seams. The lower side wall panel 11 should be tilted at an angle of no less than 75° to the horizontal. Setting the angle to 80° facilitates material flow.
[0031] In some embodiments, the outer side of the side wall panel 11 can be filled with insulation material so that the carriage has better insulation capacity and is suitable for transportation conditions of hot asphalt mixture.
[0032] Finally, the utility model also provides a dump semi-trailer, on which the carriage of the flat-push dump semi-trailer is installed.
[0033] The carriage of the flat-push dump semi-trailer of the present invention has a wider silo bottom and a relatively lower center of gravity, which is conducive to transporting special road engineering materials such as water-stabilized materials and milled materials, and the unloading time is shortened.
