[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 accompanying 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 port 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 set in the control box 10, and its control lines are 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, as well as 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 bent wall panel 29, and the upper hinge seat 25 of the loading and unloading transportation bent 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.

[0087] The lifting cylinder stabilizing mechanism is composed of two groups of stabilizing components respectively arranged at the upper and lower parts of the lifting cylinder 23; the stabilizing components are composed of a stabilizing rod 35 and two pairs of rod sleeves 22; the rod sleeve 22 is composed of two pairs of half rod sleeves, the middle part of the half rod sleeve is a circular ring, and the two ends are connecting plates; the two ends of the stabilizing rod 35 are respectively connected to the outer cylindrical surface of the circular ring of one pair of half rod sleeves, and the inner cylindrical surface of the circular ring of the pair of half rod sleeves is pressed against the inner cylindrical surface of the lifting cylinder 23, and then the inner cylindrical surface of the circular ring of the other pair of half rod sleeves is used to cover the outer cylindrical surface of the lifting cylinder 23, and the connecting plates at both ends of the half rod sleeves are fixed with bolts.

[0088] When in use, first pull the foldable 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 working; when it is necessary to lower the height of the loading and unloading transport bending assembly to adapt to the transferred 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 transport bending assembly swings clockwise around the connecting hinge pin 19, so that the height of the right end of the loading and unloading transport bending assembly is lowered (it can be adjusted to tilt 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 transport bending assembly (i.e., the transport belt) to be lowered. The belt driven roller 31 is extended into the carriage; then, the motor 3 is started to make the transport belt drive roller drive the transport belt 33 to rotate in a clockwise direction, and the items to be transferred are placed on the transport belt 33 from the left end of the loading and unloading transport fixed component (i.e., the transport belt drive roller 1), and are transferred by the transport belt 33 to the right end of the loading and unloading transport bending component (i.e., the transport 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 vehicle increases, the transfer vehicle can be started to keep an appropriate distance between the right end of the loading and unloading transport bending component (i.e., the transport 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 carry 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 provided 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 and transporting bending assembly can be lowered as much as possible, which can not only lower 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 foldable mobile belt loader of the utility model can be used for the transshipment of agricultural and sideline products such as kelp, tobacco leaves, sugar 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 product purchasing sites.
