Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] Please see Figures 1-5A feeding device for a silage harvester includes a main body 1, a running mechanism, a support mechanism, and external components. The running mechanism includes a first harvesting roller 2, a second harvesting roller 3, a transmission roller 4, a first protective plate 5, and a second protective plate 6. The first harvesting roller 2 is mounted on the main body 1 and rotatably connected to the main body 1. The second harvesting roller 3 is mounted on the main body 1 and rotatably connected to the main body 1. The transmission roller 4 is mounted on the main body 1 and rotatably connected to the main body 1. The first protective plate 5 is fixedly installed inside the main body 1 and rotatably connected to the first harvesting roller 2. The second protective plate 6 is fixedly installed on the main body 1 and rotatably connected to the second harvesting roller 3. The support mechanism includes a support plate 7, a roller 8, a connecting frame 9, and a first bolt 10. The support plate 7 is mounted on the bottom of the main body 1 and slidably connected to the main body 1. The roller 8 is mounted in the support plate 7 and rotatably connected to the support plate 7. The connecting frame 9 is mounted on the support plate 7 and slidably connected to the support plate 7. The first bolt 10 is mounted on the connecting frame 9 and threadedly engaged with the main body 1.

[0032] In this embodiment, the operating mechanism includes a first harvesting roller 2, a second harvesting roller 3, a transmission roller 4, a first protective plate 5, and a second protective plate 6. During use, under the action of the first protective plate 5 and the second protective plate 6, the transmission belts inside the first protective plate 5 and the second protective plate 6 are not affected by the harvested crops when the first harvesting roller 2 and the second harvesting roller 3 rotate, so that the first harvesting roller 2 and the second harvesting roller 3 rotate simultaneously. Under the action of the first collection port 15 and the second collection port 16, the crops are transmitted to the transmission roller 4 through the action of the first harvesting roller 2 and the second harvesting roller 3, and through the action of the transmission roller 4, the crops are fed into the crushing mechanism of the silage machine, and the crushed crops are also collected.

[0033] In this embodiment, the support mechanism includes a support plate 7, a roller 8, a connecting frame 9, and a first bolt 10. During use, to prevent the main body 1, which is installed on a moving vehicle, from being suspended and potentially exerting excessive pressure on the connection, thus damaging the connection, the support plate 7 can be installed in the mounting frame 17 of the main body 1. The support plate 7 slides in the mounting groove 18 of the mounting frame 17. When the position is correct, the connecting frame 9 on the support plate 7 can be held, and the connecting frame 9 slides in the sliding groove 20 on the support plate 7. When the connecting frame 9 reaches the first threaded hole 19, the first bolt 10 can be installed on the connecting frame 9. With the cooperation of the first bolt 10 and the first threaded hole 19, the support plate 7 is fixedly installed on the main body 1, and as the main body 1 moves, the roller 8 installed in the support plate 7 also rotates.

[0034] In this embodiment, the external components include a cutting disc 11, a positioning frame 12, and a second bolt 13. During use, different cutting discs 11 need to be replaced according to different crops. The cutting disc 11 is placed in the positioning disc 21 on the first harvesting roller 2. The positioning frame 12 is then installed on the cutting disc 11. The positioning rod 23 on the positioning frame 12 is inserted into the positioning hole 22 in the positioning disc 21. As the second bolt 13 in the positioning frame 12 is rotated, the second bolt 13 engages with the second threaded hole 24 on the first harvesting roller 2, thereby pushing the positioning block into the positioning hole 22, making the rotation of the cutting disc 11 more stable.

[0035] Example 2:

[0036] In summary, during use, the external components need to be installed on the main body 1 first, and different cutting discs 11 need to be replaced according to different crops. The cutting disc 11 is then placed into the positioning disc 21 on the first harvesting roller 2. A positioning frame 12 is then installed on the cutting disc 11. The positioning rod 23 on the positioning frame 12 is inserted into the positioning hole 22 in the positioning disc 21. As the second bolt 13 in the positioning frame 12 is rotated, it engages with the second threaded hole 24 on the first harvesting roller 2, thus pushing the positioning block into the positioning hole 22, making the rotation of the cutting disc 11 more stable. After the cutting disc 11 is installed, the support mechanism of the main body 1 is installed. To prevent the main body 1, when mounted on a traveling vehicle, from being suspended and potentially causing excessive pressure on the connection points, a support plate 7 can be installed in the mounting frame 17 of the main body 1. The support plate 7 slides in the mounting groove 18 of the mounting frame 17. Once the position is correct, the connecting bracket on the support plate 7 can be held. 9. At this time, the connecting frame 9 slides in the sliding groove 20 on the support plate 7. When the connecting frame 9 reaches the first threaded hole 19, the first bolt 10 can be installed on the connecting frame 9. With the cooperation of the first bolt 10 and the first threaded hole 19, the support plate 7 is fixedly installed on the main body 1. As the main body 1 moves, the roller 8 installed in the support plate 7 also rotates. After everything is installed, the main body 1 starts to operate. At this time, under the action of the first protective plate 5 and the second protective plate 6, the transmission belt inside the first harvesting roller 2 and the second harvesting roller 3 can be unaffected by the harvested crops when they rotate, so that the first harvesting roller 2 and the second harvesting roller 3 rotate simultaneously. Under the action of the first collection port 15 and the second collection port 16, the crops are transmitted to the transmission roller 4 under the action of the first harvesting roller 2 and the second harvesting roller 3, and under the action of the transmission roller 4, the crops are fed into the crushing mechanism of the silage machine, and the crushed crops are also collected.

[0037] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
