Simultaneously, two supporting columns are added to the lower part of the loading and unloading transportation fixed component, and a double set of lifting cylinders is used, along with a lifting cylinder stabilization mechanism. This maintains the stability of both the loading and unloading transportation fixed component and the loading and unloading transportation bending component. Furthermore, when the lifting cylinder is at its lowest position on the loading machine, its telescopic rod is fully retracted, protecting the lifting cylinder and telescopic rod from wind and rain corrosion. Moreover, the lifting cylinder is always under pressure during use, thus improving its impact resistance during loading and unloading, resulting in good stability and reliable operation. In addition, when the control motor reverses, the unloading function is realized, so it can both load and unload trucks. Attached Figure Description

[0062] The frame consists of two frame beams 9, two or more (three in this example) frame crossbeams 38, and one or more (one in this example) frame support beam 44. The two frame beams 9 are arranged in a left-right direction (one in front and one in back). The frame crossbeams 38 are arranged in a front-back direction (left, center-right, right) to connect the two frame beams 9 into one unit. The frame support beam 44 is arranged in a left-right direction to connect the center-right and right frame crossbeams 38, and is used to support the control box 10, oil pump 11, and oil tank 12.

[0063] The mobile device consists of a pair of universal wheels 6, a pair of traveling wheels 13, a traveling wheel axle 14, and a pair of universal wheel connecting beams 7. The pair of universal wheel connecting beams 7 are respectively located on the outer side of the left side of the two frame straight beams 9 (i.e., the front and rear sides, mainly used to increase the distance between the two universal wheels 6 and improve the stability of the whole machine). The pair of universal wheels 6 are respectively located below the outer end of the pair of universal wheel connecting beams 7 (i.e., the outer overhang end). The traveling wheel axle 14 extends through the right end of the two frame straight beams 9 in the front-rear direction and then installs the traveling wheels 13.

[0064] The loading and unloading transportation equipment consists of loading and unloading transportation fixing components and loading and unloading transportation bending components.

[0065] The loading and unloading transport fixing component is lower on the left and higher on the right. Its lower left part is connected to the left end of the frame, and its lower right part is supported by the upper ends of two upward-standing columns 17 respectively set on the front and rear sides of the upper right part of the frame (i.e., the upper right part of the front and rear frame straight beams 9).

[0066] The loading and unloading transportation fixing assembly consists of a pair of loading and unloading transportation fixing wall panels 8, one or more (two sets in this example) loading and unloading transportation crossbeams 37, four or more (ten sets in this example) upper support roller assemblies 28, two or more (four sets in this example) lower support roller assemblies 27, a transport belt 33, a transport belt drive roller assembly, and a power assembly. Each loading and unloading transportation crossbeam 37 has a loading and unloading transportation crossbeam pad 36 attached to each end.

[0067] The loading and unloading transport fixing wall panel 8 is a long strip with outward-facing bent edges on all sides. The upper part of the bent edge is inclined outward at an angle α of 5-30° (15° in this example). The upper right end of the loading and unloading transport fixing wall panel 8 is perpendicular to the upper bent edge, with a fixed hinge boss 34 in the middle and a leftward-sloping lower part (to accommodate the loading and unloading transport bending wall panel 29 during bending). A lower fixed hinge boss 4 is also provided on its lower left side for connecting to the hinge end of the left side of the frame straight beam 9 via a lower hinge pin 5. The two loading and unloading transport fixing wall panels 8 are basically symmetrical and identical, except that the loading and unloading transport fixing wall panel 8 installed in front has a fork groove 47 on its lower left side to facilitate the installation of the transport belt drive roller 1.

[0068] Two loading and unloading transport beams 37 are arranged in a front-to-back direction on the left and right sides of a pair of loading and unloading transport fixed wall panels 8, respectively. The loading and unloading transport beam pads 36 at both ends are connected to the inner sides of the pair of loading and unloading transport fixed wall panels 8. Eight of the ten sets of upper support roller assemblies 28 have their axes evenly arranged in a front-to-back direction. Their front and rear ends are connected to the upper middle part of the pair of loading and unloading transport fixed wall panels 8, respectively. An additional set of upper support roller assemblies 28 is added between the first and second sets and the second and third sets of upper support roller assemblies 28 on the left side to enhance the impact resistance of the transport belt 33. The axes of the lower support roller assemblies 27 are also evenly arranged in a front-to-back direction. Their front and rear ends are connected to the lower middle part of the pair of loading and unloading transport fixed wall panels 8, respectively.

[0069] The conveyor belt drive roller assembly consists of a conveyor belt drive roller 1 with a central shaft and a pair of conveyor belt drive roller bearing seats 39. The conveyor belt drive roller bearing seats 39 are respectively located in the middle of the outer side of the left end of the loading and unloading transport fixed wall panel 8. The two ends of the central shaft of the conveyor belt drive roller 1 pass through the conveyor belt drive roller bearing seats 39 respectively, and one end (the front end in this example) passes out and connects to the power output end of the power assembly.

[0070] On the outer cylindrical surface of the conveyor belt drive roller 1, there are also mesh-like raised patterns to increase the friction between the outer cylindrical surface of the conveyor belt drive roller 1 and the conveyor belt 33 and prevent slippage.

[0071] The power assembly consists of an electric motor 3, a reducer 45 (in this example, a worm gear reducer) and a power mounting platform 2. The power mounting platform 2 (which is "L" shaped, with the lower "I" being the mounting plate and the left "I" being the reinforcing rib) is located on the lower part of the left side of the loading and unloading transport fixing wall panel 8 on the front or rear side (in this example, the front side). The reducer 45 is mounted on the power mounting platform 2. The power output end of its worm gear (i.e., the power output end after the reducer 45 has reduced speed) is connected to the front end of the central shaft of the conveyor belt drive roller 1, and the input end of its worm (i.e., the power input end of the reducer 45) is connected to the output shaft of the electric motor 3. The (worm gear) reducer 45 and the electric motor 3 are integrated into one unit.

[0072] The upper surface of the conveyor belt 33 is provided with anti-slip ridges. After passing around the left side of the outer cylindrical surface of the conveyor belt drive roller 1, its upper and lower ends pass around the upper parts of each upper support roller assembly 28 and lower support roller assembly 27 to the right, and then extend towards the loading and unloading transport bending assembly.

[0073] The loading and unloading transport bending assembly consists of a pair of loading and unloading transport bending wall panels 29, one or more (two sets in this example) loading and unloading transport crossbeams 37, four or more (eight sets in this example) upper support roller assemblies 28, two or more (four sets in this example) lower support roller assemblies 27, a transport belt 33, and a transport belt driven roller assembly.

[0074] The two identical symmetrical loading and unloading transport bent wall panels 29 are similar to the loading and unloading transport fixed wall panel 8, and are also long strips. Their edges are all bent outwards, with the upper part inclined outwards at an angle α of 5-30° (15° in this example). The upper part of the left end is perpendicular to the upper bent edge, and the middle part of the left end is a bending hinge boss 20. The lower part of the left end is inclined to the right (to accommodate the loading and unloading transport fixed wall panel 8 during bending). The lower middle part of the right end has an adjustment slot 43 to the left, which is used to adjust the position of the conveyor belt driven roller assembly, thereby adjusting the tension of the conveyor belt 33, and facilitating the installation of the conveyor belt driven roller assembly.

[0075] The loading and unloading transport beams 37 are arranged in a front-to-back direction, and their two ends are respectively connected to the loading and unloading transport beam pads 36. The loading and unloading transport beam pads 36 are installed on the left and right sides of the inner side of a pair of loading and unloading transport bent wall plates 29. The axes of the upper supporting roller assembly 28 are evenly arranged in a front-to-back direction, and their front and rear ends are respectively connected to the upper middle part of a pair of loading and unloading transport bent wall plates 8. The axes of the lower supporting roller assembly 27 are evenly arranged in a front-to-back direction, and their front and rear ends are respectively connected to the lower middle part of a pair of loading and unloading transport bent wall plates 29. The axis of the driven roller assembly of the transport belt is set in a front-to-back direction at the middle of the right end of a pair of loading and unloading transport bent wall plates 29.

[0076] The driven roller assembly of the conveyor belt consists of a conveyor belt driven roller 31 with a central shaft, a pair of conveyor belt driven roller bearing seats 30, and a pair of sliding adjustment mechanisms for the conveyor belt driven roller bearing seats.

[0077] The sliding adjustment mechanism for the conveyor belt driven roller bearing seats consists of an adjustment bracket 32 shaped like a "ᄃ", a guiding rib 41, an adjustment screw 42, and an adjustment nut 46.

[0078] The upper and lower parts of the adjustment bracket 32 are symmetrical, and the cross-section of the "—" part on its upper surface is in the shape of a "Г" (as shown in the appendix Figure 7 ). A guiding rib 41 parallel to the upper "—" is also provided in the middle of the "I" part on the left side of this "Г" cross-section; in the middle of the upper and lower surfaces of the outer shell of the conveyor belt driven roller bearing seat 30, guiding grooves are provided (not marked in the appendix Figure 7 and are matched with the guiding rib 41), and an adjustment pulling bracket 40 is also provided at the left end of the outer shell of the conveyor belt driven roller bearing seat 30 (as shown in the appendix Figure 8 ). The adjustment pulling bracket 40 is rectangular, and a rectangular through groove is opened in the middle for accommodating the right end of the adjustment screw 42.

[0079] The adjustment bracket 32 is arranged at the position of the adjustment slot 43 on the outer side of the right end of the loading and unloading transport bending wall panel 29 (after the central shafts at both ends of the conveyor belt driven roller 31 pass through this adjustment slot 43, they then pass through the conveyor belt driven roller bearing seat 30). The guiding grooves on the upper and lower surfaces of the outer shell of the conveyor belt driven roller bearing seat 30 are sleeved on the guiding rib 41. After the right end of the adjustment screw 42 is screwed into the adjustment nut 46 arranged at the left end of the "ᄃ"-shaped adjustment bracket 32, it is then screwed into the screw hole at the left end of the adjustment pulling bracket 40 and enters the rectangular through groove of the adjustment pulling bracket 40. A locking nut is also installed on the adjustment screw 42 on the left side of the adjustment nut 46 to prevent the adjustment screw 42 from loosening.

[0080] After the conveyor belt 33 bypasses the right side of the outer cylindrical surface of the conveyor belt driven roller 31, its upper and lower ends respectively bypass the upper parts of each upper supporting roller assembly 28 and lower supporting roller assembly 27 to the left in sequence, and then extend to the loading and unloading transport fixed assembly, making the conveyor belt 33 form a loop.

[0081] A fixed hinge boss 34, a bent hinge boss 20, and a connecting hinge pin 19 form a loading and unloading transport fixed and bent connection hinge assembly, and the connecting hinge pin 19 rotatably connects (i.e., hinges) the fixed hinge boss 34 and the bent hinge boss 20.

[0082] The lifting device consists of a hydraulic station and two identical lifting assemblies.

[0083] The hydraulic station consists of an oil pump 11, an oil tank 12, and a control valve (not shown in the attached diagram). The oil pump 11 and the oil tank 12 are mounted on the frame crossbeam 38 and the frame support beam 44 of the machine 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 located inside the control box 10, and its other end is connected to the oil tank 12. One end of the oil inlet pipe 16 and the oil return pipe 21 are connected to the oil inlet and oil return port of the lifting cylinder 23, respectively, and their other ends are connected to the control valve.

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

[0085] The lifting assembly consists of two sets of lifting cylinder mechanisms and a lifting cylinder stabilization mechanism.

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

[0087] The stabilizing mechanism of the lifting cylinder consists of two sets of stabilizing components respectively installed on the upper and lower parts of the lifting cylinder 23. The stabilizing components consist of a stabilizing tie rod 35 and two sets of tie rod sleeves 22. The tie rod sleeve 22 consists of two sets of half tie rod sleeves, with a ring in the middle and connecting plates at both ends. The two ends of the stabilizing tie rod 35 are respectively connected to the outer cylindrical surface of the ring of one half tie rod sleeve, and the inner cylindrical surface of the ring of the half tie rod sleeve is pressed against the inner cylindrical surface of the lifting cylinder 23. Then, the inner cylindrical surface of the ring of the other half tie rod sleeve is used to cover the outer cylindrical surface of the lifting cylinder 23, and the connecting plates at both ends of the half tie rod sleeve are fixed with bolts.

[0088] In use, first pull the bending mobile belt loading and unloading machine of this embodiment to the transfer site. Then, start the control button of the oil pump 11 on the control box 10, and the oil pump 11 will start working. When it is necessary to lower the height of the loading and unloading transport bending assembly to accommodate the transfer vehicle, operate the control valve on the control box 10 to send the pressurized oil through the return oil pipe 21 to the upper part of the lifting cylinder 23. 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 tilt to the lower right). Then, the transfer vehicle can be adjusted to allow the right end of the loading and unloading transport bending assembly (i.e., the transport belt) to be lowered. The driven roller 31 extends into the carriage; then, the motor 3 is started, causing the conveyor belt drive roller to rotate clockwise with the conveyor belt 33. The items to be transferred are placed on the conveyor belt 33 from the left end of the loading and unloading transport fixed component (i.e., at the conveyor belt drive roller 1), and are transferred by the conveyor belt 33 to the right end of the loading and unloading transport bending component (i.e., at the conveyor belt driven roller 31), where they are taken off by the operator and stacked in the transfer car. As the number of items in the transfer car increases, the transfer car can be moved slightly to maintain an appropriate distance between the right end of the loading and unloading transport bending component (i.e., at the conveyor belt driven roller 31) and the stacking position in the carriage, thereby reducing the labor intensity of the operators.

[0089] When it is necessary to unload items from the transfer vehicle, first adjust the right end of the loading and unloading transport bending assembly to a suitable height for the transfer vehicle. Then, reverse the motor 3 to make the conveyor belt drive roller rotate counterclockwise with the conveyor belt 33. At the same time, transfer the items to be unloaded from the right end of the loading and unloading transport bending assembly to the left end of the loading and unloading transport fixing assembly on the transfer vehicle, and then have the operator remove them.

[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 transportation fixed assembly and at the upper and lower parts of the left end of the loading and unloading transportation bending assembly, and the conveyor belt 33 is always above all the upper supporting roller assemblies 28 and lower supporting roller assemblies 27, the conveyor belt 33 can always be kept taut when the loading and unloading transportation bending assembly bends, and can carry the items to be transferred.

[0091] When not in use, the right end of the loading and unloading transport bending assembly can be lowered as much as possible. This will not only lower the height of the machine's center of gravity and improve safety, but also reduce the exposed length of the telescopic rod 24, thus improving the safety and reliability of the equipment.

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