[0049] Preferably, the midpoint of the upper end surface of the recovery cylinder 203 is coplanar with the midpoint of the rotating shaft 207 .

[0050] Preferably, when the device is tilted upward to transport goods, one end of the first guide mechanism 500 provided on the first transfer mechanism 100 is lifted upward, and one end of the second guide mechanism 600 provided on the second transfer mechanism 200 is lifted upward, wherein the height of the other end of the second transfer mechanism 200 is lower than the height of the first guide mechanism 500, which facilitates the smooth transfer of the goods on the first transfer mechanism 100 to the second transfer mechanism 200.

[0051] A crossbeam 301 is provided in the middle of the bracket 300 , a reinforcing rib 303 is provided between the crossbeam 301 and the bracket 300 , and an electric support rod 302 is provided on one side of the reinforcing rib 303 .

[0052] Preferably, the main function of the electric support rod 302 is to provide support. When one end of the second transfer mechanism 200 is lifted upward, one end of the electric support rod 302 is also gradually lifted upward, and the support plate at the upper end of the electric support rod 302 is hinged to the electric support rod 302. The support plate on the electric support rod 302 can fit the bottom surface of the frame plate 208 for support.

[0053] The base 400 includes a bottom groove 401, one end of the bottom groove 401 is movably connected to the bottom surface of the first transfer mechanism 100 through a hinge joint 404, and the other end is provided with a buffer pad 403; an electric telescopic rod 402 is provided in the bottom groove 401, the fixed section of the electric telescopic rod 402 is placed in the bottom groove 401, and the upper end of the movable section of the electric telescopic rod 402 is movably connected to the bottom surface of the first transfer mechanism 100.

[0054] Preferably, the height of the fixed section of the electric telescopic rod 402 is not higher than the height of the buffer pad 403. When one end of the first transfer mechanism 100 contacts the buffer pad 403, the first transfer mechanism 100 is in a horizontal state.

[0055] The first guiding mechanism 500 includes a double-sided guiding block 501, which is in the shape of a triangular prism, with one end of the double-sided guiding block 501 pointing to the first transfer mechanism 100; the rear end of the double-sided guiding block 501 is fixed to the frame of the first transfer mechanism 100 through a fixed shell 504; if the second transfer mechanism 200 is only provided at one side of the first transfer mechanism 100, the double-sided guiding block 501 is in the shape of a right-angled triangular prism.

[0056] The bottom surface of the double-sided guide block 501 is in contact with the upper end surface of the conveyor belt of the first transfer mechanism 100 , and transmission components 503 are provided on both sides of the inside of the double-sided guide block 501 . The transmission components 503 are driven by the third drive motor 502 on the outside of the double-sided guide block 501 .

[0057] Preferably, the goods are transported along the first conveyor belt 101. When the goods are transported to the first guide mechanism 500, the double-sided guide blocks 501 guide the goods from the middle to both sides. The goods are first piled up on both sides of the double-sided guide blocks 501. After that, due to the thrust of the first conveyor belt 101, the goods fall onto the second transfer mechanism 200.

[0058] At the same time, the transmission member 503 will gradually push the goods in the direction of the second transfer mechanism 200 during the transportation of the goods, so as to avoid excessive accumulation of goods at the double-sided guide blocks 501 during the transportation process, which will reduce the transportation efficiency of the device. At the same time, when the goods are transported, some of the goods will be stranded on both sides of the double-sided guide blocks 501 due to the first conveyor belt 101 or the goods themselves, and the transmission member 503 can transport this part of the goods to the second transfer mechanism 200.

[0059] The second guiding mechanism 600 includes a single-sided guiding block 601, a gasket 602 is provided at the upper end of the single-sided guiding block 601, the bottom surface of the gasket 602 is connected to a movable rod 606, the inside of the movable rod 606 is hollow, and the lower end of the movable rod 606 is threadedly connected to a threaded rod 605; the lower end of the threaded rod 605 is movably connected to the bottom surface of the single-sided guiding block 601, and the lower end of the threaded rod 605 is connected to the output end of the fourth driving motor 603 through a bevel gear set 604.

[0060] Preferably, the threaded rod 605 passes through the bottom surface of the movable rod 606 .

[0061] Preferably, when the second transfer mechanism 200 performs horizontal transportation, the fourth drive motor 603 drives the threaded rod 605 to rotate, the movable rod 606 gradually moves outward, and the distance between the gasket 602 and the single-side guide block 601 gradually increases until the gasket 602 contacts the ground;

[0062] In practical applications, a transmission member 503 may also be provided on the side of the second guide mechanism 600 facing the second transmission belt 201 to play the same role.

[0063] The transmission member 503 includes a rotating shaft 503b, which is movably connected to the double-sided guide blocks 501, a crawler track 503a is arranged on the outer side of the rotating shaft 503b, and a dial plate 503c is arranged on the outer side of the crawler track 503a.

[0064] The second driving motor 202 is close to one end of the second transmission belt 201 where a connector 205 is disposed.

[0065] Preferably, when transporting goods upward, a horizontal transport device can be placed in the middle of the second transfer mechanism 200 to finally unload the goods. It should be noted that the height of the horizontal transport device must be lower than the height of the top of the second transfer mechanism 200.

[0066] During use, when the goods need to be transported upward, first lift one end of the first transfer mechanism 100 through the electric telescopic rod 402. Note that the tilt angle of the first transfer mechanism 100 when lifted cannot be greater than the maximum tilt angle of the goods when it is lifted; during the lifting process of the first transfer mechanism 100, the second transfer mechanism 200 will also be lifted following the first transfer mechanism 100. When the first transfer mechanism 100 completes the lifting and tilting work, the rotating motor 206 starts to start, and by tightening the pull rope 204, one end of the second transfer mechanism 200 gradually tilts downward. Similarly, the horizontal tilt angle of the second transfer mechanism 200 cannot be greater than the maximum transportation tilt angle of the goods. When the upper end surface of the second transfer mechanism 200 is at least 10 cm higher than the target height, the rotating motor 206 stops working, and the electric support rod 302 starts to support the second transfer mechanism 200. Finally, a horizontal transportation device is used to receive the goods on the second transfer mechanism 200.

[0067] When the goods are transported horizontally, the position of the first transfer mechanism 100 remains unchanged, the rotating motor 206 drives the pull rope 204 to tighten, and the second transfer mechanism 200 completes a 90° clockwise flip. After that, the rotating motor 206 slowly releases the pull rope 204 until the second transfer mechanism 200 is parallel to the bottom surface. After that, the fourth drive motor 603 starts to extend the gasket 602 downward until the gasket 602 contacts the ground, completing the adjustment of the second transfer mechanism 200 under horizontal transportation.

[0068] In summary, the device uses a multi-stage structural design to transport the goods to the target height under the premise that each section meets the maximum transportation angle of the goods. At the same time, the device also meets the transportation of the goods in the horizontal direction. At the same time, in the multi-stage structure, the transition of goods between adjacent two sections of the transportation structure is smooth, and there will be no leakage problem.
