[0032] A frame-type unloading vehicle body 1, the frame-type unloading vehicle body 1 comprises a vehicle body frame 11 and a pulley 12 fixedly connected to the bottom of the vehicle body frame 11, and the pulley 12 is rotatably mounted on the pouring port of the concrete pouring cavity;

[0033] A concrete hopper 2 is installed on the vehicle body frame 11 and is located inside all the pulleys 12 .

[0034] The adjustable discharge vehicle provided by the embodiment of the utility model uses a frame-type discharge vehicle body 1 as a carrier, and uses the vehicle body frame 11 to integrate the concrete hopper 2. The concrete hopper 2 is firmly connected to the pump pipe or the discharge hopper to continuously collect the discharged concrete and discharge it into the concrete pouring cavity without leakage. At the same time, the pulley 12 is used to roll with the concrete pouring cavity to achieve movement along its pouring port, thereby achieving the purpose of a complete pouring process.

[0035] Therefore, the adjustable discharge cart of the utility model embodiment not only reduces the scattering of concrete during the pouring process, avoids pollution to the formwork and surrounding sites, reduces concrete loss to a certain extent, and increases the turnover number of formworks; it is also simple to operate and practical in function, reduces the difficulty of pouring concrete for low walls, and improves construction efficiency.

[0036] In a further optional embodiment of the utility model, the frame-type discharge vehicle body 1 is symmetrically provided with foldable handles 3 on both sides in the length direction, and the ends of the foldable handles 3 are hinged to the bottom of the vehicle frame 11. The vehicle frame 11 is provided with a blocking body 31 that enables the foldable handles 3 to be flipped unidirectionally to the side opposite to the moving direction.

[0037] It should be noted that applying force to the foldable handle 3 described in this embodiment can more conveniently and quickly realize the movement of the adjustable discharge vehicle to facilitate the rapid and accurate adjustment of the concrete discharge position.

[0038] More specifically, the foldable handle 3 can be a steel pipe handle that assists in propelling the trolley. The inner end of the steel pipe handle is rotatably mounted on the vehicle body frame 11 through a pin shaft and a connecting plate, thereby realizing a 180° flip of the steel pipe handle relative to the vehicle body frame 11. By providing a blocking body 31 on one side of the moving direction of the steel pipe handle, the steel pipe handle can be limited to flip only a certain angle, such as 90°. When not in use, the steel pipe handle is folded to fit the vehicle body frame 11, and flipped 90° when in use, locking the steel pipe handle in place to push the vehicle body frame 11 to move.
