[0054] The lifting device is composed of a hydraulic station 16, an oil pipe assembly and two identical lifting cylinder assemblies. The lower parts of the two identical lifting cylinder assemblies are respectively installed on the left and right sides of the rear end of the frame 13, and the upper parts are respectively installed at the lower position of the middle part of the two left and right transport bracket slot plates 11.

[0055] The hydraulic station 16 includes an attached oil tank 20 and is installed on the middle and rear part of the frame 13 .

[0056] The oil pipe assembly is composed of an oil delivery pipe 51 , an oil delivery pipe tee 53 , an oil return pipe 50 , an oil return pipe tee 52 , two oil delivery branch pipes 54 and an oil return branch pipe 18 .

[0057] The lifting cylinder assembly is composed of a lifting cylinder 21, a telescopic rod 19, an upper hinge seat 17 and a lower hinge seat 35. The upper hinge seat 17 is installed at the lower position of the middle of the left and right transport bracket slot plates 11, and the lower hinge seat 35 is installed at the upper rear end of the frame 13. The lower end of the lifting cylinder 21 is rotatably hinged on the lower hinge seat 35, and the upper end of the telescopic rod 19 extending from the upper part of the lifting cylinder 21 is rotatably hinged on the upper hinge seat 17.

[0058] One end of the oil delivery pipe 51 in the oil pipe assembly is connected to the hydraulic station 16, and the other end is connected to the oil delivery pipe tee 53; the two outlets of the oil delivery pipe tee 53 are respectively connected to one end of two oil delivery branch pipes 54, and the other ends of the two oil delivery branch pipes 54 are respectively connected to the oil inlets at the bottom of the two lifting cylinders 21; the oil inlets at the bottom of the two lifting cylinders 21 are respectively connected to one end of two oil return branch pipes 18, and the other ends of the two oil return branch pipes 18 are respectively connected to the two oil return ports of the oil return pipe tee 52; the oil outlet of the oil return pipe tee 52 is connected to one end of the oil return pipe 50, and the other end of the oil return pipe 50 is connected to the hydraulic station 16.

[0059] The axis of the lifting cylinder assembly (ie, the lifting cylinder 21 and the telescopic rod 19 ) in the lifting device is perpendicular to the horizon formed by the lower end points of the universal wheel 6 and the running wheel 25 .

[0060] The counting assembly is composed of an infrared probe 33, a probe mounting support rod 12, a signal line 34 and a counting display screen 14. The probe mounting support rod 12 is mounted on the upper right side surface of the front middle part of the left and right transport bracket slot plates 11, and the infrared probe 33 is mounted on the upper end thereof; the counting display screen 14 is mounted on the lower right side surface of the front middle part of the left and right transport bracket slot plates 11 on the right side, and the infrared probe 33 is connected to the counting display screen 14 through a signal line 34.

[0061] The electric control box 15 is installed at the middle and rear part of the frame 13, and introduces the mains power line, and connects the control power line to the motor 4 and the hydraulic station 14 respectively.

[0062] When in use, the belt-type mobile loader of this embodiment is first pulled to the site to be transferred, and then the rising button on the electric control box 15 is activated, and the hydraulic station 16 starts to work. The pressure oil in the hydraulic station 16 is sent to the oil delivery pipe tee 53 through the oil delivery pipe 51, and then connected to the two oil delivery branch pipes 54 through its two outlets to respectively connect to the oil inlets at the lower parts of the two lifting cylinders 21, pushing the telescopic rods 19 in the two lifting cylinders 21 to extend upward, and then pushing the rear end of the transport device to swing counterclockwise around the lower end of the universal wheel 6, so that the rear end of the transport device rises upward. At this time, the pressure oil in the upper chambers of the two lifting cylinders 21 returns to the hydraulic station 16 through the two upper return oil branches 18 and the return oil pipe tee 52 and the return oil pipe 50. When the height of the rear end of the transport device rises to a suitable level, the rising button is closed, and the hydraulic station 16 stops sending and returning oil.

[0063] During the process of the telescopic rod 19 extending upward, since the front end of the frame 13 can swing around the frame connecting pin 9, the rear end can also swing around the pin shaft (not marked in the figure) of the lower hinge seat 35, and the upper end of the telescopic rod 19 can swing around the pin shaft (not marked in the figure) of the upper hinge seat 17, it can ensure that the axis of the lifting cylinder assembly (i.e., the lifting cylinder 21 and the telescopic rod 19) in the lifting device is always in a vertical state with the horizon formed by the lower end points of the universal wheel 6 and the running wheel 25, so that the lifting cylinder 21 and the telescopic rod 19 maintain a vertical support type, so that the force they bear conforms to the principle of mechanics. At the same time, since the front end of the transport device is close to the universal wheel 6, the height lowered by the front end of the transport device is very small.

[0064] Next, the transport button on the electric control box 15 is activated, the motor 4 starts to rotate, and the output shaft of the motor 4 drives the worm in the worm gear reducer 2 to rotate, which in turn drives the worm in the worm gear reducer 3 to rotate at a reduced speed, and transmits it to the drive shaft 27, which in turn drives the drive roller 26, together with the transport belt 22 and the driven roller 30 to circulate (clockwise direction, see attached Figure 1 Or 2), at this time, the objects to be transported (such as bundled kelp, tobacco leaves, etc.) can be loaded onto the transport belt 22 from the front end of the transport device at a very low position, and then transported to the higher position at the rear end. When the objects to be transported are brought to the rear end (i.e., the highest point) of the transport device by the transport belt 22, they can be stacked or loaded onto a truck.

[0065] When it is necessary to lower the loading height, the lowering button on the electric control box 15 is activated, and the pressure oil in the hydraulic station 16 enters the upper cavity of the lifting cylinder 21 through the return oil pipe 50, the return oil pipe tee 52, and the return oil branch pipe 18, pushing the telescopic rod 19 in the lifting cylinder 21 to retract downward, thereby pushing the rear end of the transport device to swing clockwise around the lower end of the universal wheel 6, so that the rear end of the transport device is lowered downward; at the same time, the pressure oil in the lifting cylinder 21 returns to the hydraulic station 16 through the oil delivery branch pipe 54, the oil delivery pipe tee 53 and the oil delivery pipe 51. When the height of the rear end of the transport device drops to a suitable level, the lowering button is turned off, and the hydraulic station 16 stops delivering and returning oil. At the same time, since the front end of the transport device is close to the universal wheel 6, the height of the front end of the transport device is very small, and the front end of the transport device itself is not high from the ground, so it will not affect the loading of the objects to be transported.

[0066] During use, when each object to be transported passes over the infrared probe 33 in the counting component, the infrared probe 33 will output a counting signal to the counting display screen 14 through the signal line 34, which will be accumulated and displayed thereon.

[0067] The belt-type mobile loader of the present invention can be used for the transportation 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.
