[0029] The lifting mechanism 11 adopts a hydraulic cylinder 111, the bottom end of the hydraulic cylinder 111 is hinged on the support frame 1, and the end of the piston rod of the hydraulic cylinder 111 is hinged on the bottom; through the extension and retraction of the hydraulic cylinder 111, the support plate 2 can be driven to rotate around the axis of the movable shaft 21; at the same time, a long hole 121 is provided on the base 12, and the piston rod of the hydraulic cylinder 111 passes through the long hole 121.

[0030] The driving device 4 includes two driving wheels 41 and two driven wheels 43, the two driving wheels 41 are coaxial, and the two driven wheels 43 are coaxial; one of the conveyor belts 3 is sleeved on the outside of one of the driving wheels 41 and one of the driven wheels 43, and the other conveyor belt 3 is sleeved on the outside of the remaining driving wheel 41 and the remaining driven wheel 43, and the conveyor belt 3 is adapted to the driven wheel 43 and the driving wheel 41; a driving shaft 42 is arranged between the two driving wheels 41, the driving shaft 42 passes through the two driving wheels 41, the driving shaft 42 is coaxial with the two driving wheels 41, the driving shaft 42 is fixedly connected to the two driving wheels 41, and the driving shaft 42 passes through the two driving wheels 41. It is movably connected to the base 12 through a bearing; a driven shaft 44 is arranged between the two driven wheels 43, the driven shaft 44 passes through the two driven wheels 43, the driven shaft 44 is coaxial with the two driven wheels 43, the driven shaft 44 is fixedly connected to the two driven wheels 43, and the driven shaft 44 is movably connected to the base 12 through a bearing; the driving device 4 also includes a driving motor 45 arranged on the base 12, the output shaft of the driving motor 45 is fixedly connected to the driving shaft 42, and the output shaft of the driving motor 45 is coaxial with the driving shaft 42; the base 12 is composed of multiple parts, that is, it has multiple panel structures, which can facilitate the installation and connection of the conveyor belt 3, the driving shaft 42, etc.

[0031] By driving the driving shaft 42 to rotate through the driving motor 45, the two driving wheels 41 can be driven to rotate synchronously. With the cooperation of the conveyor belt 3 and the driven wheel 43, the two conveyor belts 3 can move synchronously.

[0032] At the same time, the support plate 2 is inserted into the two conveyor belts 3, and two first conveying mechanisms 5 and two second conveying mechanisms 6 are installed on the support plate 2, and the two first conveying mechanisms 5 and the two second conveying mechanisms 6 all pass through the two conveyor belts 3; the two first conveying mechanisms 5 are respectively connected to a first fixing bar 51, the two first fixing bars 51 are parallel and correspondingly arranged, and a plurality of supporting casters 7 are evenly distributed on the top of the two first fixing bars 51; the two first fixing bars 51 are both located in one of the conveyor belts 3, and the two first fixing bars 51 are both inclined, and the inclination angle of the two first fixing bars 51 is consistent with the inclination angle of the conveyor belt 3; each supporting caster 7 on the first fixing bar 51 contacts the inner side of the conveyor belt 3 corresponding to the first fixing bar 51, specifically, the supporting caster 7 contacts the inner side of the upper straight part of the conveyor belt 3.

[0033] The two second conveying mechanisms 6 are respectively connected to a second fixing bar 61, and the two second fixing bars 61 are arranged in parallel. The two second fixing bars 61 are respectively arranged in one-to-one correspondence with the two first fixing bars 51, and a plurality of supporting casters 7 are evenly distributed on the top of the two first fixing bars 51; the two second fixing bars 61 are both located in the other conveyor belt 3, and the two second fixing bars 61 are both inclined, and the inclination angle of the two second fixing bars 61 is consistent with the inclination angle of the conveyor belt 3; each supporting caster 7 on the second fixing bar 61 contacts the inner side of the corresponding conveyor belt 3, specifically, the supporting caster 7 on the second fixing bar 61 contacts the inner side of the upper straight part of the corresponding conveyor belt 3.

[0034] like Figure 5 As shown, the supporting caster 7 adopts a universal ball 71; as a replacement method, the universal ball 71 can be replaced with a roller (a roller with a supporting seat, a rotating shaft and other structures). When replaced with a roller, the rotation axis of the roller must be perpendicular to the length direction of the straight part of the conveyor belt 3; that is, when the conveyor belt 3 moves, the conveyor belt 3 can drive the roller to rotate.

[0035] The two first conveying mechanisms 5 respectively drive the two first fixed bars 51 to move linearly in the horizontal direction, and the two second conveying mechanisms 6 respectively drive the two second fixed bars 61 to move linearly in the horizontal direction; the first fixed bars 51 and the second fixed bars 61 have the same structure, that is, the length, width and thickness of the first fixed bars 51 are respectively consistent with the length, width and thickness of the second fixed bars 61; since the two conveyor belts 3 are arranged at intervals, there is a spacing between the two conveyor belts 3, and the width of the first fixed bar 51 and the second fixed bar 61 is smaller than the spacing between the two conveyor belts 3.

[0036] like Figure 1 As shown, each first fixed bar 51 is located inside the corresponding conveyor belt 3, and each supporting caster 7 on the first fixed bar 51 contacts the inner side of the upper straight portion of the corresponding conveyor belt 3; each second fixed bar 61 is located inside the corresponding conveyor belt 3, and each supporting caster 7 on the second fixed bar 61 contacts the inner side of the upper straight portion of the corresponding conveyor belt 3; at this time, the driving motor 45 drives the active shaft 42 to rotate, and in the process of the conveyor belt 3 transporting the agricultural product packaging box from a low place to an upper place (the packaging box is placed on two conveyor belts 3), the supporting caster 7 contacts the inner side of the conveyor belt 3, that is, the supporting caster 7 has a supporting effect on the conveyor belt 3; at the same time, the conveyor belt 3 can drive the supporting caster 7 to rotate to avoid hindering the operation of the conveyor belt 3, thereby realizing the stable transportation of the packaging box by the conveyor belt 3, that is, improving the transportation stability of the conveyor belt 3.

[0037] When the two first conveying mechanisms 5 drive the two first fixing bars 51 to move out of the conveyor belt 3 and move between the two conveyor belts 3, the movement displacements of the two first fixing bars 51 are the same; at the same time, the two second conveying mechanisms 6 drive the second fixing bars 61 to move out of the conveyor belt 3, and the movement direction and displacement of the second fixing bars 61 are respectively the same as the movement direction and displacement of the first fixing bars 51, that is, the states of the first fixing bars 51 and the second fixing bars 61 are as follows: Figure 6 At this time, the piston rod of the hydraulic cylinder 111 extends and drives the support plate 2 to rotate around the axis of the movable shaft 21, so that the end of the support plate 2 away from the rotating shaft is adjacent to the inner side of the conveyor belt 3, that is, Figure 7 In the state shown, except for the universal ball 71 adjacent to the movable shaft 21, the top of each remaining universal ball 71 (i.e., the top of the supporting caster 7) is higher than the height of the corresponding part of the conveyor belt 3 and the universal ball 71. At this time, placing the packaging box on the universal ball 71 can enable the packaging box to slide from a high place to a low place, that is, the packaging box can be transferred without power at this time; when the packaging box slides down to near the movable shaft 21 and the packaging box contacts the surface of the conveyor belt 3, the conveyor belt 3 can also generate resistance to the packaging box, which helps to slow down or stop the packaging box, thereby facilitating subsequent loading and unloading or transfer.

[0038] The conveyor belt 3 in this embodiment can not only convey the packaging boxes, but also facilitate the deceleration or stop of the packaging boxes when the packaging boxes slide from a high place to a low place.

[0039] This embodiment changes the state and, under the action of the supporting casters 7, realizes the transportation of the packaging box from a high place to a low place without the aid of a power device, thereby saving energy. At the same time, during the transportation process of the conveyor belt 3, the supporting casters 7 contact the conveyor belt 3 to improve the transportation stability of the conveyor belt 3.

[0040] Embodiment 2

[0041] See also Figure 1-Figure 8 This embodiment is based on the first embodiment. In order to prevent the packaging box from falling off during the sliding process, two first brackets 8 and two second brackets 9 are detachably provided on the support frame 1. A guard rod 10 is fixedly connected between the two first brackets 8, and a guard rod 10 is also fixedly connected between the two second brackets 9. The two guard rods 10 are used to prevent the packaging box from falling off.

[0042] Specifically, the first bracket 8 and the second bracket 9 can be detachably arranged on the support frame 1 by means of plugging, snapping or screws, so as to facilitate the rapid installation or removal of the first bracket 8 and the second bracket 9.

[0043] Embodiment 3

[0044] This embodiment is based on the first embodiment. Both the first conveying mechanism 5 and the second conveying mechanism 6 adopt existing linear modules, and the linear modules can be used to drive the first fixing bar 51 and the second fixing bar 61 to move horizontally and linearly.
