In summary, the cutting width of the cutting table of the tomato harvester with adjustable cutting width provided by the invention can be effectively adjusted so as to improve the harvesting effect of the tomato harvester.
On the basis of the above embodiment, it is preferable that both sides of the end of the header frame 5 are provided with a vertical frame connection plate 51 and a sliding concave plate 52 horizontally provided on the frame connection plate 51; the end of the seedling separating device 1 is provided with a vertical seedling separating connecting plate 11 and a sliding convex plate 12 connected with the seedling separating connecting plate 11, the sliding convex plate 12 can slide along a sliding concave plate 52, and the seedling separating connecting plate 11 is provided with a mounting hole 14 for mounting a positioning pin 13.

It should be noted that, the seedling supporting belt 42 is disposed above the conveying belt 3, and a gap between the seedling supporting belt 42 and the conveying belt 3 is referred to as a header feeding gap, wherein, after the tomato plants enter the seedling supporting belt 42, the tomato plants can be effectively cut off by the cutting knife 2, then fall into the conveying belt 3 by the seedling supporting belt 42, and finally be conveyed to the next procedure by the conveying belt 3. When the yield of the tomato plants is large, the feeding gap of the cutting table needs to be increased so as to avoid the blockage of the conveying process of the tomato plants, at the moment, the seedling supporting oil cylinder 46 can be driven to operate, and when the seedling supporting oil cylinder 46 extends out of the non-rod end hinged with the seedling supporting frame 41, the seedling supporting frame 41 can be jacked up and lifted so as to increase the space between the seedling supporting belt 42 and the conveying belt 3, so that the tomato plants smoothly enter the conveying belt 3. When the yield of tomato plants is smaller, the feeding gap of the cutting table needs to be reduced so as to avoid lower conveying efficiency of the tomato plants, at the moment, the seedling supporting oil cylinder 46 can be driven to operate, when the seedling supporting oil cylinder 46 and the hinged rod end of the seedling supporting frame 41 retract, the seedling supporting frame 41 can be enabled to fall back down, so that the space between the seedling supporting belt 42 and the conveying belt 3 is reduced, and the tomato plants can enter the conveying belt 3 more quickly.
The shape, structure, size, material and the like of the seedling support 41, the seedling support belt 42, the seedling support motor 43, the conveying wheel 44 and the conveying shifting plate 45 can be determined according to actual conditions and actual requirements in the actual application process.
Preferably, the conveying poking plates 45 are uniformly distributed along the circumferential direction of the conveying wheel 44 so as to improve the lifting and righting effects of the conveying poking plates 45 on tomato plants, and the tomato plants close to the ground can enter the seedling raising belt 42 more smoothly.
Preferably, the conveying deflector 45 includes a first deflector 451 for use when the seedling separating apparatus 1 approaches the header frame 5, a second deflector 452 for use when the seedling separating apparatus 1 does not move relative to the header frame 5, and a third deflector 453 for use when the seedling separating apparatus 1 is away from the header frame 5, the first deflector 451 having a width smaller than that of the second deflector 452, and the second deflector 452 having a width smaller than that of the third deflector 453.

Thus, the conveying shifting plate 45 can be adjusted according to the installation position of the seedling separating device 1, and the second shifting plate 452 can be installed when the seedling separating device 1 is at the middle installation position, as shown in fig. 14; when the seedling separation device 1 is far away from the header frame 5, a third shifting plate 453 may be installed as shown in fig. 18; when the seedling separating apparatus 1 approaches the header frame 5, a first pulling plate 451 may be installed, as shown in fig. 16. The above-mentioned operation of replacing the conveying shifting plate 45 is to ensure that the distance between the seedling separating device 1 and the seedling supporting device 4 is not too large or too small during the harvesting operation, so as to avoid the harvesting loss.
The shapes, structures, sizes, materials, etc. of the first dial 451, the second dial 452, and the third dial 453 may be determined according to actual conditions and actual demands during the actual use.
It should be noted that, the first dial 451, the second dial 452, and the third dial 453 are mentioned in this application, where the first, the second, and the third are merely to distinguish the positions, and there is no sequential distinction.
