[0002] Currently, for auger conveyor systems, multiple augers are typically connected sequentially. Adjacent augers are usually connected by a shaft head structure and a transmission mechanism. However, in the existing technology, the hexagonal shaft hole will have a misalignment problem during the assembly process with the shaft head of the transmission mechanism. This misalignment will cause a difference in the phase angle between the end of the blade of the preceding auger and the beginning of the blade of the following auger. If the blade angle is not reasonable, the most obvious consequence will be interference between the blades. More difficult to detect, it will cause material conveying to be unsmooth, blade wear, increased conveying resistance and load, and damage to the transmission mechanism. Summary of the Invention

[0012] In any of the above technical solutions, the bevel gear and the target shaft are integral structures; or the bevel gear and the target shaft are separate structures and are detachably connected by splines.

[0039] The following reference Figures 1 to 13 The present application describes an auger 10, a conveying system, and a grain combine harvester according to some embodiments thereof.

[0040] Example 1

[0041] See Figures 1 to 5 , Figures 8 to 11As shown, an embodiment of this application provides an auger 10, including: a main shaft 1, blades 2, a first shaft head 3, and a second shaft head 4; wherein, the blades 2 are disposed on the outer wall of the main shaft 1 and extend spirally along the outer wall of the main shaft 1;

[0042] Along the axial direction of the main shaft 1, the first shaft head 3 and the second shaft head 4 are respectively disposed at both ends of the main shaft 1, and both the first shaft head 3 and the second shaft head 4 are formed with shaft holes 5 for connecting the external target shaft 202; the shaft holes 5 of the first shaft head 3 and the second shaft head 4 include a positioning surface 51 and an insertion surface 52, and the target shaft 202 is formed with an auxiliary positioning surface 2021 and an auxiliary insertion surface 2022, and the auxiliary positioning surface 2021 is adapted to the positioning surface 51 and is used to position the auger 10 to maintain its installation phase, and the auxiliary insertion surface 2022 is adapted to the insertion surface 52 and is used to assemble the main shaft 1 of the auger 10 and the target shaft 202 together.

[0043] As described above, the shaft hole 5 employs a structure with a positioning surface 51 and an insertion surface 52. The insertion surface 52 of the shaft hole 5 engages with the auxiliary insertion surface 2022 of the target shaft 202, thus assembling the shaft hole 5 with the target shaft 202. The positioning surface 51 of the shaft hole 5 engages with the auxiliary positioning surface 2021 of the target shaft 202, unlike the engagement surface 52 with the auxiliary insertion surface 2022. This prevents incorrect assembly and achieves precise positioning. In other words, it effectively prevents angular misalignment after shaft head assembly, thus solving the problem of phase difference in auger blade connection, ensuring blade phase consistency, and also ensuring the transmission structure. Furthermore, it effectively prevents errors during assembly, improves production efficiency, and significantly reduces product quality risks.

[0044] In this embodiment, preferably, as follows: Figure 2 As shown, the positioning surface 51 is an arc surface, and along the central axis of the main shaft 1, the center of the projection of the arc surface coincides with the central axis of the main shaft 1; the insertion surface 52 is a plane.

[0045] As can be seen from the structure described above, the center of the arc of the positioning surface 51, that is, the arc surface, is made to coincide with the central axis of the main shaft 1 to avoid overall skewing after assembly, thereby greatly ensuring the rationality of the angle between the shaft head and the blade.

[0046] In this embodiment, preferably, as follows: Figure 3 and Figure 5 As shown, each shaft hole 5 includes five planar insertion surfaces 52 and one arc-shaped positioning surface 51.

[0047] As can be seen from the structure described above, the five planar insertion surfaces 52 and the arc-shaped positioning surfaces 51 form a hexagonal structure, which not only prevents incorrect assembly but also facilitates assembly and manufacturing.

[0048] In this embodiment, preferably, as follows: Figure 3 As shown, the included angle between any two adjacent planar interlocking surfaces 52 is 120°; the lengths of the five planar interlocking surfaces 52 are all equal, that is, along the axis of the main shaft 1, the side lengths of the projections of the five planar interlocking surfaces 52 are all equal.

[0049] As can be seen from the structure described above, designing any shaft hole 5 into a structure similar to a regular hexagon not only ensures assembly accuracy but also serves as a foolproof method and facilitates manufacturing. Of course, this is not the only option; the lengths of the five planar insertion surfaces 52 can also be unequal, depending on the specific design requirements.

[0050] It should be noted that any shaft hole 5 is not limited to including five planar insertion surfaces 52 and one arc-shaped positioning surface 51. It may also include four planar insertion surfaces 52 and one arc-shaped positioning surface 51, or three planar insertion surfaces 52 and one arc-shaped positioning surface 51, or five planar insertion surfaces 52 and one arc-shaped positioning surface 51, or three planar insertion surfaces 52 and two arc-shaped positioning surfaces 51, etc. In other words, it is sufficient to ensure that any shaft hole 5 includes one planar insertion surface 52 and one arc-shaped positioning surface 51, which is enough to achieve the purpose of incorrect installation. The specific design depends on the actual needs.

[0051] In this embodiment, preferably, as follows: Figure 2 As shown, along the axial direction of the main shaft 1, the outer edge of the projection of the blade 2 away from the main shaft 1 is circular, and its center coincides with the center of the axial direction of the main shaft 1. This allows for the smooth and rapid transport of materials, preventing excessive accumulation of materials in one place and thus avoiding blockages. Of course, this is not the only benefit.

[0052] Example 2

[0053] See Figures 6 to 8 As shown, Embodiment 2 of this application also provides a conveying system, including the auger 10 described in Embodiment 1 above. Therefore, it has all the beneficial technical effects of the auger 10. The same technical features and beneficial effects will not be repeated here.

[0054] In this embodiment, preferably, as follows: Figures 6 to 8 As shown, the conveying system also includes a transmission mechanism 20, and any two adjacent augers 10 are connected through the transmission mechanism 20. The transmission mechanism 20 forms the aforementioned target shaft 202.

[0055] As can be seen from the structure described above, the transmission mechanism 20 can drive all the augers to rotate and work, thereby realizing the conveying of materials.

[0056] It should be noted that the target shaft 202 can adopt one of the following two structures: First, the target shaft 202 is integrally formed from the rear part of the bevel gear 201 described below; Second, the bevel gear 201 has an internal spline hole, and a target shaft 202 with an external spline at one end and a positioning surface 51 and an insertion surface 52 at the other end is inserted into the spline hole. Of course, it is not limited to these two structures, and the specific choice depends on the actual needs.

[0057] In this embodiment, preferably, as follows: Figure 6 and Figure 7 As shown, the transmission mechanism 20 is a gear transmission structure.

[0058] As can be seen from the structure described above, gear transmission mechanisms are stable and reliable, suitable for applications in the transmission field, and have a long service life. Of course, this is not the only advantage they offer.

[0059] In this embodiment, preferably, as follows: Figure 6 , Figure 7 As shown, any two adjacent augers 10 are arranged at an angle, and the transmission mechanism 20 includes two meshing bevel gears 201. Both bevel gears 201 have a target shaft 202. The target shaft 202 of one bevel gear 201 is connected to the shaft hole 5 of the first shaft head 3 or the second shaft head 4 of the adjacent auger 10, and the target shaft 202 of the other bevel gear 201 is connected to the shaft hole 5 of the first shaft head 3 or the second shaft head 4 of the adjacent auger 10.

[0060] As can be seen from the structure described above, the meshing of bevel gears 201 can realize the transfer and transmission between two augers 10 at different angles, thus meeting the usage requirements.

[0061] Further, preferably, such as Figure 10 and Figure 11 As shown, the bevel gear 201 and the target shaft 202 are an integral structure, which has high overall strength, is not easily damaged, and has a long service life. Of course, it is not limited to this; other structures can also be used, for example: see [link to related document]. Figure 13 As shown, the bevel gear 201 and the target shaft 202 are separate structures and are detachably connected by a spline. This is a detachable connection structure, which facilitates disassembly and maintenance in the future.

[0062] In this embodiment, preferably, as follows: Figure 6 As shown, there are three augers 10, one of which is set horizontally and the other is set vertically.

[0063] As can be seen from the structure described above, the three augers 10 working together can realize the material transfer along an L-shaped path, thereby transporting the material from point A to point B, which is completely different in height and orientation, thus meeting the conveying requirements.

[0064] It should be noted that the number of augers 10 is not limited to three; it can also be two or more, such as four or five, etc., and the number of transmission mechanisms 20 is one less than the number of augers 10. The specific selection depends on the actual needs.

[0065] Furthermore, the orientation of the auger 10 is not limited to the aforementioned horizontal or vertical setting. It can also be designed according to actual needs, such as forming an obtuse or acute angle with the horizontal or vertical direction, etc. The specific design depends on the actual needs.

[0066] In this embodiment, preferably, as follows: Figure 6 As shown, the conveying system also includes a conveying channel 30, and the transmission mechanism 20 and the auger 10 are both located within the conveying channel 30.

[0067] As described above, the structure confines the material within the conveying channel 30, allowing it to be transported within a designated area and preventing it from scattering into other areas. Of course, this is not the only possibility; curved conveying pipes, etc., can also be used.

[0068] Example 3

[0069] Embodiment 3 of this application also provides a grain combine harvester, which includes the conveying system described in Embodiment 1 above. Therefore, it has all the beneficial technical effects of the conveying system, and the same technical features and beneficial effects will not be repeated here.

[0070] 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.
