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

[0040] Example 1

[0041] See also Figures 1 to 5 、 Figures 8 to 11As shown, an embodiment of the present application provides an auger 10, comprising: a main shaft 1, blades 2, a first shaft head 3, and a second shaft head 4; wherein the blades 2 are arranged on the outer wall of the main shaft 1 and extend in a spiral shape 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 arranged at both ends of the main shaft 1, and the first shaft head 3 and the second shaft head 4 are both formed with an axial hole 5 for connecting the external target shaft 202; the axial hole 5 of the first shaft head 3 and the second shaft head 4 includes a positioning surface 51 and a plug-in surface 52, and the target shaft 202 is formed with an auxiliary positioning surface 2021 and an auxiliary plug-in 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 plug-in surface 2022 is adapted to the plug-in surface 52 and is used to assemble the main shaft 1 of the auger 10 and the target shaft 202 together.

[0043] According to the structure described above, it can be known that, for the shaft hole 5, a structure in which the positioning surface 51 and the plug-in surface 52 cooperate is adopted, wherein the plug-in surface 52 of the shaft hole 5 cooperates with the auxiliary plug-in surface 2022 of the target shaft 202, thereby realizing the assembly of the shaft hole 5 and the target shaft 202, and the positioning surface 51 of the shaft hole 5 cooperates with the auxiliary positioning surface 2021 of the target shaft 202, which is different from the cooperation between the plug-in surface 52 and the auxiliary plug-in surface 2022, thereby playing a role in preventing installation errors and realizing precise positioning. In other words, it can effectively prevent the problem of angular misalignment after assembly of the shaft head, thereby solving the problem of phase difference in the connection of the auger blades, ensuring the consistency of the blade phase, and also playing a role in ensuring the transmission structure. At the same time, error prevention can be effectively achieved during the assembly process, which improves production efficiency and greatly reduces product quality risks.

[0044] In this embodiment, preferably, 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 plug-in surface 52 is a plane.

[0045] According to the structure described above, the center of the arc of the positioning surface 51, i.e. the arc surface, is made to coincide with the central axis of the main shaft 1, thereby avoiding overall skewness after assembly and greatly ensuring the rationality of the angle between the shaft head and the blade.

[0046] In this embodiment, preferably, Figure 3 and Figure 5 As shown, any axial hole 5 includes five planar plug-in surfaces 52 and one arc-shaped positioning surface 51 .

[0047] According to the structure described above, the five planar plug-in surfaces 52 and the arc-shaped positioning surface 51 form a hexagonal structure, which not only prevents incorrect installation but also facilitates assembly and processing.

[0048] In this embodiment, preferably, Figure 3 As shown, the angle between any two adjacent planar plug-in surfaces 52 is 120°; the lengths of the five planar plug-in surfaces 52 are all equal, that is, along the axial direction of the main shaft 1, the side lengths of the projections of the five planar plug-in surfaces 52 are all equal.

[0049] As can be seen from the above-described structure, designing any of the axial holes 5 to resemble a regular hexagonal deformation structure 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 plug-in surfaces 52 can also be unequal, depending on actual needs.

[0050] It should be noted that: any axial hole 5 is not limited to including five planar plug-in surfaces 52 and one arc-shaped positioning surface 51, but may also include four planar plug-in surfaces 52 and one arc-shaped positioning surface 51, or include three planar plug-in surfaces 52 and one arc-shaped positioning surface 51, etc., or include five planar plug-in surfaces 52 and one arc-shaped positioning surface 51, or include three planar plug-in surfaces 52 and two arc-shaped positioning surfaces 51, etc. In other words, it is mainly necessary to ensure that any axial hole 5 includes a planar plug-in surface 52 and a arc-shaped positioning surface 51, that is, it can achieve the purpose of incorrect installation, and the specific design is based on actual needs.

[0051] In this embodiment, preferably, Figure 2 As shown, along the axis 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 axis center of the main shaft 1, which can smoothly and quickly transport the material and avoid excessive accumulation of material in a certain place, which may cause blockage, etc. Of course, it is not limited to this.

[0052] Example 2

[0053] See also Figures 6 to 8 As shown, the second embodiment of the present application further provides a conveying system, including the auger 10 described in the above-mentioned first embodiment, and thus has all the beneficial technical effects of the auger 10, and the same technical features and beneficial effects are not repeated.

[0054] In this embodiment, preferably, Figures 6 to 8 As shown, the conveying system further includes a transmission mechanism 20 , and any two adjacent augers 10 are connected via the transmission mechanism 20 , and the transmission mechanism 20 forms the aforementioned target axis 202 .

[0055] According to the structure described above, it can be known that all the dragons can be driven to rotate through the transmission mechanism 20, thereby realizing the transportation of materials.

[0056] It should be noted that the target shaft 202 can adopt the following two structures. For example, the first structure is to integrally mold the target shaft 202 at the rear of the bevel gear 201 described below. The second structure is to insert the target shaft 202 into the spline hole with an internal spline hole inside the bevel gear 201. The target shaft 202 has an external spline at one end and a positioning surface 51 and an inserting surface 52 at the other end. Of course, the present invention is not limited to this structure and can be selected according to actual needs.

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

[0058] According to the structure described above, the gear transmission mechanism is stable and reliable, suitable for application in the transmission field, and has a long service life. Of course, it is not limited to this.

[0059] In this embodiment, preferably, 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, and the two bevel gears 201 are formed with a target shaft 202, and the target shaft 202 of one of the bevel gears 201 is connected to the shaft hole 5 of the first shaft head 3 or the second shaft head 4 of an adjacent augers 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 another adjacent augers 10.

[0060] According to the structure described above, it can be known that the switching and transmission between two augers 10 at different angles can be achieved through the engagement between the bevel gears 201, thereby meeting the use requirements.

[0061] Further, preferably, Figure 10 and Figure 11 As shown, the bevel gear 201 and the target shaft 202 are an integrated structure, which has high overall strength, is not easy to damage, and has a long service life. Of course, it is not limited to this, and other structures can also be used, for example: see Figure 13 As shown, the bevel gear 201 and the target shaft 202 are split structures and are detachably connected via splines, which is a detachable connection structure that facilitates subsequent disassembly and maintenance.

[0062] In this embodiment, preferably, Figure 6 As shown, there are three augers 10 , one of which is arranged along the horizontal direction, and the other one is arranged along the vertical direction.

[0063] According to the structure described above, the three augers 10 cooperate to realize material transmission in an L-shaped path, thereby transporting materials from site A to site B with completely different height and orientation, thus meeting the transportation requirements.

[0064] It should be noted that the number of augers 10 is not limited to three, but can also be two or more than three, such as four, five, etc., and the number of transmission mechanisms 20 is one less than the number of augers 10, which is selected according to actual needs.

[0065] In addition, the orientation of the auger 10 is not limited to the aforementioned horizontal or vertical setting, and can also be designed according to actual needs, such as forming an obtuse angle or an acute angle with the horizontal direction or the vertical direction, etc., specifically designed according to actual needs.

[0066] In this embodiment, preferably, Figure 6 As shown, the conveying system further includes a conveying channel 30 , and the transmission mechanism 20 and the auger 10 are both disposed in the conveying channel 30 .

[0067] According to the structure described above, the material is confined in the conveying channel 30, and can be conveyed in a designated area to avoid scattering to other areas. Of course, it is not limited to this, and an arc-shaped conveying pipe or the like can also be provided.
