Each toothed rod 3' is provided with several threshing rod teeth 4'. A feeding end 5' is provided at one end of the axial flow drum, and a spiral blade 6' is provided on the feeding end 5' to feed crops into the axial flow drum.
[0003] This type of axial flow drum is suitable for wheat threshing. However, when using this type of axial flow drum with all threshing rods (4') for high-yield rice harvesting and threshing, it will cause excessive load on the axial flow drum, making it difficult to thresh the crop and resulting in significant losses due to drum entrainment. Utility Model Content
[0004] The purpose of this application is to provide an axial flow drum and harvesting system that can, to a certain extent, compensate for the insufficient threshing capacity of the threshing rod teeth and reduce drum entrainment losses when encountering high-yield and difficult-to-thresh crops.
[0005] In a first aspect, this application provides an axial flow roller, comprising:
[0006] Roller shaft;
[0007] Multiple discs are spaced apart along the length of the roller shaft;

[0010] In a preferred embodiment, the kneading toothed plate is L-shaped, with one side being a mounting plate for connecting to the toothed bar, and the other side being a toothed surface, with a plurality of kneading teeth densely arranged along the edge of the toothed surface.
[0011] In a preferred embodiment, the tooth surface is composed of a plurality of spaced-apart tooth blocks, and the kneading teeth are respectively provided at the edges of each tooth block.
[0012] In a preferred embodiment, the mounting plate is provided with a kneading plate mounting hole, the toothed rod is provided with a mounting block, and the mounting plate of the kneading toothed plate is fixedly connected to the mounting block by bolts.
[0013] In a preferred embodiment, there is an even number of toothed bars, and the kneading toothed plate is provided at the middle position of each toothed bar that is spaced apart from one toothed bar.
[0014] In a preferred embodiment, the kneading toothed plate includes a first kneading toothed plate and a second kneading toothed plate, wherein the first kneading toothed plate and the second kneading toothed plate are disposed on the same or different toothed bars.
[0015] In a preferred embodiment, the length of the second kneading toothed plate is longer than, equal to or shorter than that of the first kneading toothed plate.
[0016] In a preferred embodiment, there is at least one second kneading tooth plate, and the first kneading tooth plate and the second kneading tooth plate are arranged adjacent to each other, or at least one of the threshing rod teeth is arranged between the first kneading tooth plate and the second kneading tooth plate.
[0017] In a preferred embodiment, a plurality of tooth mounting holes for mounting the threshing rod teeth are provided on the position occupied by the kneading tooth plate on the tooth bar.
[0018] In a preferred embodiment, the rack is arranged parallel to the roller shaft.
[0019] Secondly, this application also provides a harvesting system, including any of the axial flow drums described in the previous application.

[0044] Example 1
[0045] like Figures 1 to 4 As shown, this embodiment provides an axial flow roller, including:
[0046] A central roller shaft 1 is provided, and multiple radial discs 2 are spaced apart along the length of the roller shaft 1. Along the circumference of the radial discs 2, multiple toothed rods 3 are provided at the edge of the radial discs 2, and several threshing rod teeth 4 are spaced apart on each toothed rod 3.
[0047] A first kneading tooth plate 7 is provided on at least one toothed rod 3, and a plurality of kneading teeth 703 are provided on the outer side of the first kneading tooth plate 7 facing the rotation direction of the axial flow drum during operation.
[0048] One end of the roller shaft 1 is the feeding end 5, which is generally truncated cone-shaped, and its surface is provided with at least one spiral blade 6 to feed the crop into the roller.
[0049] Specifically, the first kneading tooth plate 7 is L-shaped, with one side being a mounting plate 701 for connecting with the tooth bar 3, and the other side being a plurality of tooth blocks 702 spaced apart, with a tooth block gap 704 between each tooth block 702, which can reduce some of the cutting resistance; and densely arranged kneading teeth 703 are respectively provided at the edge of each tooth block 702.
[0050] The mounting plate 701 is provided with a rubbing plate mounting hole, and the corresponding mounting block is provided on the toothed bar 3. The mounting plate 701 of the first rubbing toothed plate 7 and the mounting block of the toothed bar 3 are detachably connected by bolts.
[0051] Meanwhile, on the toothed rod 3, in the position occupied by the first kneading toothed plate 7, next to the mounting block, several tooth mounting holes for mounting the threshing rod teeth 4 are also provided. When harvesting ordinary crops (such as wheat) or when the breakage rate is high, the first kneading toothed plate 7 can be disassembled and replaced with the threshing rod teeth 4 to meet the threshing needs of the crop.
[0052] In other embodiments, the first kneading toothed plate 7 may not need to be disassembled or replaced. In this case, the mounting plate 701 can be directly welded to the toothed rod 3 as a whole, which is specifically used for threshing high-yield and difficult-to-thresh crops.
[0053] In a preferred embodiment, there is an even number of toothed bars 3, and a first kneading toothed plate 7 is provided at the middle position of every other toothed bar 3. As in this embodiment, there are a total of 6 toothed bars 3, and a first kneading toothed plate 7 is provided at the middle position of each of the three toothed bars 3 that are spaced apart from each other.
[0054] The first kneading toothed plate 7 on each toothed bar 3 can be set at the same distance from the feeding end 5, or at different distances.
[0055] The lengths of the first kneading teeth 7 can be the same or different.
[0056] In the preferred embodiment, the rack 3 is arranged parallel to the roller shaft 1, and the disc 2 is perpendicular to both the roller shaft 1 and the rack 3.
[0057] In another preferred embodiment, a second kneading toothed plate 8 is also included. The second kneading toothed plate 8 and the first kneading toothed plate 7 are disposed on the same toothed bar 3, and the kneading teeth of the second kneading toothed plate 8 are arranged in the same direction as the kneading teeth 703 of the first kneading toothed plate 7.
[0058] Similarly, the second kneading toothed plate 8 can also be disposed on two adjacent toothed bars 3, and the projections of the second kneading toothed plate 8 and the first kneading toothed plate 7 in the horizontal direction are offset. The kneading teeth of the second kneading toothed plate 8 are arranged in the same direction as the kneading teeth 703 of the first kneading toothed plate 7.
[0059] The structure of the second kneading toothed plate 8 is basically the same as that of the first kneading toothed plate 7. Its length can be set as needed, and can be longer than, equal to or shorter than the first kneading toothed plate 7.
[0060] There is at least one second kneading tooth plate 8, and the first kneading tooth plate 7 and the second kneading tooth plate 8 are arranged adjacent to each other, or at least one threshing rod tooth 4 is arranged between the first kneading tooth plate 7 and the second kneading tooth plate 8.
[0061] The number and position of the first kneading toothed plate 7 and the second kneading toothed plate 8 can be adjusted according to the actual needs of the crop.
[0062] By setting a second rubbing toothed plate 8, crops can be cut over a wider range, thereby further improving threshing capacity.
[0063] When encountering high-yield and difficult-to-thresh crops, such as high-yield rice, the rubbing toothed plate can compensate for the insufficient threshing capacity of the threshing rod teeth, thereby improving the threshing capacity to a certain extent and reducing roller entrainment losses. When harvesting ordinary crops or crops with a high breakage rate, the rubbing toothed plate can be disassembled and restored to the state of threshing rod teeth.
[0064] Example 2
[0065] This application also provides a harvesting system, including the harvester described above. It therefore possesses all the beneficial effects of a harvester, which will not be specifically elaborated upon here.
[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
