[0081] The fixed hinge boss 34, the bent hinge boss 20 and the connecting hinge pin 19 constitute a loading and unloading transportation fixed folding connecting hinge assembly, and the connecting hinge pin 19 rotatably connects the fixed hinge boss 34 and the bent hinge boss 20 (ie, hinges).

[0082] The lifting device is composed of a hydraulic station and two sets of identical lifting components.

[0083] The hydraulic station is composed of an oil pump 11, an oil tank 12 and a control valve (not shown in the attached drawings). The oil pump 11 and the oil tank 12 are arranged on the frame cross beam 38 and the frame support beam 44 of the frame; one end of the oil pump 11 is connected to the oil tank 12, and the other end is connected to one end of the control valve; the control valve is arranged in the control box 10, and the other end thereof is connected to the oil tank 12; one end of the oil inlet pipe 16 and the oil return pipe 21 are respectively connected to the oil inlet and oil return ports of the lifting cylinder 23, and the other ends thereof are respectively connected to the control valve.

[0084] The AC power line is introduced into the control box 10 to provide power for the oil pump 11 and the motor 3; the electric control switch is arranged in the control box 10, and its control line is connected to the oil pump 11 and the motor 3 respectively, for controlling the start and stop of the oil pump 11 and the motor 3.

[0085] The lifting assembly is composed of two sets of lifting cylinder mechanisms and a lifting cylinder stabilizing mechanism.

[0086] The lifting cylinder mechanism is composed of a lifting cylinder 23, a telescopic rod 24, an upper hinge seat 25 and a lower hinge seat 15, an oil inlet pipe 16 and an oil return pipe 21; the upper hinge seat 25 is arranged at the lower position of the middle left part of the loading and unloading transportation bending wall panel 29, and the upper hinge seat 25 of the loading and unloading transportation bending wall panel 29 is rotatably connected to the upper end of the telescopic rod 24 through the upper hinge pin 26; the lower hinge seat 15 is arranged on the right end of the frame straight beam 9, and the lower end of the lifting cylinder 23 is rotatably connected to the right end of the frame straight beam 9 through the lower hinge pin 18 of the lifting cylinder.

[0088] When in use, first pull the bending mobile belt loader of this embodiment to the site to be transferred, then start the control button of the oil pump 11 on the control box 10, and the oil pump 11 starts to work; when it is necessary to lower the height of the loading and unloading transportation bending assembly to adapt to the transported vehicle, operate the control valve on the control box 10 to allow the pressure oil to be sent to the upper part of the lifting cylinder 23 through the return oil pipe 21. At this time, the telescopic rod 24 retracts downward, and the left end of the loading and unloading transportation bending assembly swings clockwise around the connecting hinge pin 19, so that the height of the right end of the loading and unloading transportation bending assembly is lowered (it can be adjusted to be tilted to the upper right, horizontal, or tilted to the lower right). Then, the transfer vehicle can adjust its position to allow the right end of the loading and unloading transportation bending assembly (i.e., the transport belt) to be lowered. The conveyor belt driven roller 31 is extended into the carriage; then, the motor 3 is started to make the conveyor belt driving roller drive the conveyor belt 33 to make a clockwise circular rotation, and the items to be transferred are placed on the conveyor belt 33 from the left end of the loading and unloading transport fixing assembly (i.e., the conveyor belt driving roller 1), and are transferred by the conveyor belt 33 to the right end of the loading and unloading transport bending assembly (i.e., the conveyor belt driven roller 31), where they are taken down by the operator and stacked in the transfer vehicle; as the number of items in the transfer carriage increases, the transfer vehicle can be started to keep an appropriate distance between the right end of the loading and unloading transport bending assembly (i.e., the conveyor belt driven roller 31) and the position to be stacked in the carriage, thereby reducing the labor intensity of the operator.

[0089] When it is necessary to unload the items on the transfer vehicle, the right end of the loading and unloading transport bending assembly can be adjusted to a height suitable for the transfer vehicle first, and then the motor 3 is reversed to allow the transport belt drive roller to drive the transport belt 33 to rotate in a counterclockwise direction. At the same time, the items to be unloaded are transferred from the transfer vehicle through the right end of the loading and unloading transport bending assembly to the left end of the loading and unloading transport fixing assembly, and then removed by the operator.

[0090] Since upper supporting roller assemblies 28 and lower supporting roller assemblies 27 are arranged at the upper and lower parts of the right end of the loading and unloading transport fixing assembly and the upper and lower parts of the left end of the loading and unloading transport bending assembly, and the transport belt 33 is always above all the upper supporting roller assemblies 28 and the lower supporting roller assemblies 27, when the loading and unloading transport bending assembly bends and changes, the transport belt 33 can always be in a taut state and can carry the items to be transferred.

[0091] When it is not necessary to work, the right end of the loading, unloading, transporting and bending assembly can be lowered as much as possible, which can not only reduce the height of the center of gravity of the whole machine and improve safety, but also reduce the exposed length of the telescopic rod 24 and improve the safety and reliability of the equipment.

[0092] The bending type mobile belt loader and unloader of the present invention can be used for the transportation of agricultural and sideline products such as kelp, tobacco leaves, beets, dried hemp, industrial products, semi-finished products and luggage, and is suitable for use in factories, shopping malls, stations, docks and agricultural and sideline products purchasing sites.
