DETAILED DESCRIPTION

[0023] The following is combined with Figures 1-6 This application is described in further detail.

[0024] The present application embodiment discloses a collecting device of a self-propelled leafy vegetable orderly harvester, referring to Figures 1-3 In this embodiment, the collecting device includes a collecting rack 1, a front conveying roller 2, a driving mechanism 5, a middle conveying roller 3, a first linkage mechanism 6, a rear conveying roller 4, a second linkage mechanism 7, and a blocking mechanism 8. Two collecting racks 1 are provided, and the two collecting racks 1 are symmetrically mounted on both sides of the rear end of the harvester body 9, and both collecting racks 1 have an arc-shaped structure.

[0025] Specifically, the collecting rack 1 includes a front end plate 10, a middle end plate 11, and a rear end plate 12, wherein the front side of the front end plate 10 is mounted on the rear end side of the harvester body 9 by multiple bolts, and a load-bearing rod is mounted between the bottom ends of the two front end plates 10 by bolts, so that the two front end plates 10 are mounted more stably. The front side of the middle end plate 11 is mounted on the rear side of the front end plate 10 by multiple bolts, and a load-bearing rod is also mounted between the bottom ends of the two middle end plates 11 by bolts, so that the two middle end plates 11 are mounted more stably; and side plates are mounted on the top ends of the two middle end plates 11 by multiple bolts. The setting of the side plates can effectively block the cut leafy vegetables, thereby preventing the leafy vegetables from being thrown out from both sides of the middle end plate 11 during transportation, thereby facilitating the collection of more leafy vegetables.

[0026] The front side of the rear end plate 12 is rotationally connected to the rear side of the middle end plate 11, and the bottom ends of the two rear end plates 12 are provided with a bearing plate through bolt mounting, so that the two rear end plates 12 are more stably mounted; meanwhile, an angle adjusting assembly is arranged between one side of one of the middle end plates 11 and one side of the rear end plate 12 connected thereto, which is used for effectively adjusting the swing angle of the rear end plate 12.

[0027] Specifically, referring to Figure 3 and Figure 4 In this embodiment, the angle adjusting assembly includes a fixed L-shaped seat 13, a sliding L-shaped seat 14, a limiting piece 15, an adjusting piece 16, an adjusting rod 17, an adjusting shaft 18 and an adjusting spring 19. The one side of the fixed L-shaped seat 13 is mounted on one side of the middle end plate 11. The sliding L-shaped seat 14 is slidingly mounted on the inner side of the fixed L-shaped seat 13 through the limiting piece 15, and the limiting piece 15 is a limiting bolt. A threaded hole is formed in one side of the sliding L-shaped seat 14 and is threadedly connected with the limiting bolt. A waist-shaped hole is formed in the fixed L-shaped seat 13, and the limiting bolt passes through the waist-shaped hole and is screwed into the threaded hole, so that the nut of the limiting bolt abuts against the surface of the fixed L-shaped seat 13, thereby enabling the sliding L-shaped seat 14 to slide on the fixed L-shaped seat 13 through the limiting bolt.

[0028] Meanwhile, the adjusting piece 16 is an adjusting bolt, which is threadedly connected to one side of the fixed L-shaped seat 13, and the threaded end of the adjusting bolt abuts against one side of the sliding L-shaped seat 14. By rotating the adjusting bolt, the sliding L-shaped seat 14 can be pushed to move forward on the fixed L-shaped seat 13 through the limiting bolt.

[0029] One side of the adjusting rod 17 is hingedly connected to the front side of the rear end plate 12, and the adjusting rod 17 has an arc shape. One end of the adjusting shaft 18 is fixedly connected to the end of the adjusting rod 17 away from the rear end plate 12. Through holes are formed in the fixed L-shaped seat 13 and the sliding L-shaped seat 14, and the end of the adjusting shaft 18 away from the adjusting rod 17 passes through the sliding L-shaped seat 14 and the fixed L-shaped seat 13 in sequence along the two through holes. The adjusting spring 19 is sleeved on the adjusting shaft 18, and one end of the adjusting spring 19 abuts against the outer side of the adjusting plate 62, and the other end of the adjusting spring 19 abuts against the inner side of the sliding L-shaped seat 14.

[0030] When it is necessary to adjust the angle of the rear end plate 12, the adjusting bolt is rotated to push the threaded rod of the adjusting bolt to move the sliding L-shaped seat 14 forward, and the sliding L-shaped seat 14 extrudes the adjusting spring 19 to shrink the adjusting spring 19, so as to push the adjusting plate 62 to swing the rear end plate 12 inward.

[0031] On the contrary, when the adjusting bolt is rotated in the opposite direction, the threaded rod of the adjusting bolt moves backward, causing the adjusting spring 19 to reset, thereby pushing the sliding L-shaped seat 14, thereby resetting the adjusting rod 17, and the rear end plate 12 swings outward under the action of gravity, thereby enabling the angle of the rear end plate 12 to be adjusted.

[0032] In addition, refer to Figures 1-3 In this embodiment, four front conveyor rollers 2 are provided. Two of the front conveyor rollers 2 have one end rotatably connected to the inner side of one front end plate 10, and the other two front conveyor rollers 2 have one end rotatably connected to the inner side of the other front end plate 10. The front conveyor rollers 2 on the same side are arranged parallel to each other, and the front conveyor rollers 2 on both sides correspond to each other one-to-one. The drive mechanism 5 is installed inside the rear end of the harvester body 9.

In this way, by setting different heights, a U-shaped collection space is formed, which facilitates the collection of more leafy vegetables.

[0034] One end of the middle conveying roller 3 located at the front end cooperates with the driving mechanism 5, so that when the driving mechanism 5 drives the front conveying roller 2 to rotate, it can also drive the middle conveying roller 3 at the front end to rotate; the first linkage mechanism 6 is arranged between the ends of the middle conveying rollers 3 that extend out of the middle end plate 11, and the first linkage mechanism 6 is used to simultaneously link the middle conveying rollers 3 with each other; when the driving mechanism 5 drives the front conveying roller 2 to rotate, it can drive the middle conveying roller 3 at the front end to rotate, and then through the linkage action of the first linkage mechanism 6, the remaining four middle conveying rollers 3 rotate synchronously, thereby effectively transporting the cut leafy vegetables.

[0036] Preferably, a plurality of protective shells are installed on the two collection racks 1, and these protective shells respectively cover the driving mechanism 5, the first linkage mechanism 6 and the second linkage mechanism 7, so as to effectively protect the linkage parts of the driving mechanism 5, the first linkage mechanism 6 and the second linkage mechanism 7, thereby preventing these linkage parts from being exposed to the outside of the collection rack 1 and causing damage.

[0037] In addition, the blocking mechanism 8 is rotatably arranged between the rear ends of the two rear end plates 12 to effectively block the transported leafy vegetables, thereby preventing the leafy vegetables from being thrown out of the rear conveying roller 4. Then, the leafy vegetables are circulated, stirred and tumbled under the conveying action of the front conveying rollers 2, the middle conveying rollers 3 and the rear conveying rollers 4, which can automatically screen the leafy vegetables and effectively screen and separate the soil on the leafy vegetables, thereby shortening the progress of harvesting and repackaging the leafy vegetables, reducing the time for vegetable processing, and improving the efficiency of leafy vegetable processing.
