[0028] The asphalt mixture on-site transport and loading equipment in this embodiment includes a traveling chassis 1, a belt conveyor 2 and a hopper flap mechanism 3. The hopper flap mechanism 3 is fixed on the traveling chassis 1. The belt conveyor 2 is rotatably installed on the traveling chassis 1 through a rotating mechanism 4. The hopper flap mechanism 3 cooperates with the belt conveyor 2.

[0029] The hopper flap mechanism 3 in this embodiment includes a hopper body 31, a discharge port 32, a feed screw 33 and a discharge door 34. The hopper body 31 is fixed on the walking chassis 1, the discharge port 32 is arranged at the bottom of the hopper body 31, the discharge door 34 cooperates with the discharge port 32, the discharge port 32 is located above the rotating conveyor frame 21, the feed screw 33 is installed in the hopper body 31, the discharge door 34 is driven by the discharge cylinder 37 to control the opening and closing of the discharge port 32, a flap 35 is rotatably installed on the side of the hopper body 31, the flap 35 is driven by the flap cylinder 38, and a baffle 36 is rotatably installed on the side of the flap 35, and the baffle 36 is driven by the baffle cylinder 39.

[0030] The belt conveyor 2 in this embodiment includes a rotating conveyor frame 21 and a belt conveyor body 22. The rotating conveyor frame 21 is rotatably mounted on the walking chassis 1, and the belt conveyor body 22 is rotatably mounted on the rotating conveyor frame 21. The belt conveyor body 22 is driven by a flip cylinder 23. The belt conveyor body 22 includes an input section and an output section. The output section is foldably connected to the input section, and the output section is driven by a folding cylinder 24. Conveyor belts are provided on the rotating conveyor frame 21 and the belt conveyor body 22.

[0031] The rotating mechanism 4 in this embodiment includes a ring gear 41, a gear 42, a motor 43, a rotating frame 44, a slewing support 45, a limiting frame 46 and a limiting wheel 47. The ring gear 41 is fixed on the hopper body 31, the gear 42 is installed on the motor shaft of the motor 43, and the ring gear 41 is meshed with the gear 42. The motor 43 is installed on the rotating frame 44, the rotating frame 44 is fixed on the rotating conveying frame 21, and the rotating conveying frame 21 is installed on the walking chassis 1 through the slewing support 45. One end of the limiting frame 46 is fixed on the rotating frame 44, and the limiting wheel 47 is installed on the other end of the limiting frame 46, and the limiting wheel 47 contacts the inner wall of the ring gear 41.

[0032] Specifically, when the asphalt mixture on-site transfer and loading equipment is working, the motor 43 drives the gear 42 to rotate according to the position of the trolley. Since the gear 42 is meshed with the ring gear 41, the ring gear 41 is fixed to the hopper body 31, and the motor 43 is installed on the rotating frame 44. The rotating frame 44 is fixed to the rotating conveyor frame 21. The rotating conveyor frame 21 is rotatably connected to the walking chassis 1 through the slewing support 45, thereby realizing the angle adjustment of the belt conveyor 2, so that the discharge end of the belt conveyor body 22 is located above the trolley.

[0033] The semi-trailer insulated material truck for asphalt mixture reverses to the hopper body 31 to unload the material. The asphalt mixture in the hopper body 31 is transported to the discharge port 32 through the feeding screw 33. The discharge door 34 is opened and the asphalt mixture falls onto the belt conveyor 2. The belt conveyor 2 lifts the asphalt mixture to a height of 2.5 meters to complete the loading of the trolley. When the trolley is full, the feeding screw 33 and the discharge door 34 are closed until the asphalt mixture on the belt conveyor 2 is exhausted, which can avoid a small amount of material left on the belt conveyor 2 from quickly cooling and solidifying. The material is then transported to a narrow construction site by the trolley.

[0034] As the temperature of asphalt mixture is about 170°, the temperature requirement during paving construction shall not be lower than 140°. The hopper body 31 can be set to a double-layer hopper wall, and insulation materials can be filled in the middle, and the discharge door 34 can be equipped with built-in electric heating and constant temperature heating. Due to the high viscosity of the asphalt mixture, the belt conveyor 2 can use anti-sticking isolation agent to spray and brush the conveyor belt and scraper device at regular intervals to prevent the conveyor belt from sticking. The belt conveyor 2 adopts local anti-packing and introduces the exhaust gas of the power generation internal combustion engine to preheat and insulate the conveyor belt before the belt conveyor 2 works.

[0035] The asphalt mixture on-site transfer and loading equipment is powered by its own 20KW generator set, and all components are electrically or hydraulically driven. If there is commercial electricity access at the transfer and loading site, it can directly draw electricity to work, making the equipment both oil- and electricity-powered, or both.

[0036] When the belt conveyor 2 is folded and retracted, the asphalt mixture on-site transfer and loading equipment has an overall size of 4.5 meters * 1.6 meters * 2.4 meters. It is transported to the construction site by a road rescue flatbed trailer, and the self-contained crawler walking chassis 1 is used to drive the trailer to a slightly larger site near the construction site and put it in place.

[0037] That is to say, the asphalt mixture is transported from the mixing station to the vicinity of the construction site by a large special semi-trailer asphalt insulated truck, unloaded into the hopper body 31 of the asphalt mixture on-site transfer and loading equipment, and then transported to the end of the belt conveyor 2 through the feeding screw 33. The belt conveyor 2 lifts the asphalt mixture to a height of 2.5 meters to complete the loading process of the small dump truck, and then transported to the construction site by the small dump truck; each component of the asphalt mixture on-site transfer and loading equipment uses an electric motor acceleration and reduction gear, and the power source comes from its own 20-kilowatt generator set. If conditions permit, it can be directly connected to the commercial power supply on site. The equipment energy consumption can be either oil or electricity, which is simple and convenient.

[0038] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
