[0037] According to a first aspect of an embodiment of the present application, a grain elevator is provided. The structure and working principle of the grain elevator will be specifically described below in conjunction with Figures 1 to 3 Specifically describe the structure and working principle of the grain elevator.
[0038] According to the grain elevator provided by the embodiment of the present application, the grain elevator includes a grain bottom auger 10 and a lower housing 30 assembly. In the embodiment, the grain bottom auger 10 has an axial direction, and the grain bottom auger 10 extends along the axial direction. In the embodiment, the lower housing 30 assembly includes an inlet member 20 and a housing 30. The inlet member 20 is connected to one side of the housing 30 in the axial direction. The inlet member 20 is a grain inlet 21 extending along the axial direction. The housing 30 has a cavity 31 communicating with the grain inlet 21. The grain bottom auger 10 passes through the grain inlet 21 and is rotatably connected to the inner side of the housing 30.
[0039] In the embodiment, when observed along the axial direction, the grain inlet 21 includes an accommodating section 22 and a buffer section 23 adjacent above. The accommodating section 22 is used to accommodate the grain bottom auger 10, and the buffer section 23 is located above the grain bottom auger 10 to buffer the material conveyed by the grain bottom auger 10.
[0040] Thus, according to the grain elevator provided by the embodiment of the present application, when the feeding amount of the material at the seed material inlet of the inlet member 20 is large or the material is relatively wet, the buffer section 23 above the grain bottom auger 10 will buffer the conveyed material, alleviating the problems of material pushing and excessive material compactness, thereby alleviating the problems of difficult material transportation and easy blockage when the material is conveyed by a chain rake 60 later.
[0041] In the embodiment, the material can be, for example, grain, that is, the grain involved in the above description.
[0042] In an embodiment, when the feeding amount of the material is small, the material is generally conveyed axially by the grain bottom auger 10 within the accommodating section 22 or slightly beyond the position of the accommodating section 22. As described above, when the feeding amount of the material is large, resulting in an increase in conveying resistance, or when the material is wet, causing an increase in conveying resistance, the buffer section 23 will serve as an additional accommodating space for the material, alleviating the situation of material accumulation and excessive compaction due to the increased conveying resistance.
[0043] In the embodiment summary, as Figure 2 shown, Figure 2 part of the structure of the grain bottom auger 10, the inlet member 20, and the housing 30 are shown. In an embodiment, the grain bottom auger 10 passes through the inlet member 20, and then the shaft portion of the grain bottom auger 10 is connected to the inner side of the housing 30.
[0044] In an embodiment, the housing 30 includes two side plates that are opposite to each other axially (e.g., in the horizontal direction). One side plate is connected to the inlet member 20 and is the left side plate 32, and the other side plate is rotatably connected to the end of the grain bottom auger 10 and is the right side plate 33. In an embodiment, the end of the grain bottom auger 10 can be connected to the right side plate 33 of the housing 30 through a rotational holding support element such as a bearing. In an embodiment, the other end of the grain bottom auger 10 can be rotatably connected to the lower housing of the cleaning chamber of the harvester in the same manner.
[0045] Although not shown in Figure 2 , in practical applications, there is also an extension structure between the left side plate 32 and the right side plate 33. The extension structure, together with the left side plate 32 and the right side plate 33, encloses to form a housing 30 with a hollow interior. In an embodiment, the extension structure is shown in Figure 1 but is not labeled.
[0046] According to the grain elevator provided by the embodiment of the present application, the lower inner edge 26 of the grain inlet 21 can be arc-shaped, and the axis of the lower inner edge 26 can coincide with the axis of the grain bottom auger 10. Thus, according to the grain elevator provided by the embodiment of the present application, the lower inner edge 26 of the grain inlet 21 is arc-shaped, and the axis of the grain bottom auger 10 coincides with that of the lower inner edge 26, which can ensure that the gap width between the lower inner edge 26 of the grain inlet 21 and the grain bottom auger 10 is uniform, and the material can flow evenly between the grain bottom auger 10 and the lower side of the grain inlet 21, and it is not easy to accumulate.
[0047] According to the grain elevator provided by the embodiments of the present application, the upper inner edge 24 of the grain inlet 21 can be arc-shaped, and the upper inner edge 24 can have the same radius as the lower inner edge 26. In an embodiment, the upper inner edge 24 is a part of the grain inlet 21 that defines the buffer section 23, and it is also arc-shaped. On the one hand, it arches upward, capable of providing a certain buffer space for accommodating materials. On the other hand, as an arc shape, the upper inner edge 24 is easier to process and manufacture. Since the upper inner edge 24 and the lower inner edge 26 have the same radius, the overall shape of the grain elevator is relatively regular, making it easier to process and manufacture.
[0048] According to the grain elevator provided by the embodiments of the present application, both the upper inner edge 24 and the lower inner edge 26 can be semi-circular, and the grain inlet 21 can further include a rectangular section 25 extending between the upper inner edge 24 and the lower inner edge 26.
[0049] Thus, in an embodiment, the grain inlet 21 is defined as a substantially kidney-shaped hole structure by the upper inner edge 24, the lower inner edge 26, and the rectangular section 25 located between them. In an embodiment, the grain inlet 21 is a regular shape formed by parts of regular geometric figures, which is easier to process and manufacture. In addition, compared with the grain inlet of a part of the special-shaped housing 30 in the prior art, since a part of the elevator is a lower tensioning structure and the grain inlet requires more space, the structure of this special-shaped housing 30 is more complex, the cost is higher, and the precision requirements for parts are higher.
[0050] In an embodiment, the lower inner edge 26, the rectangular section 25, and the upper inner edge 24 substantially divide the grain inlet 21 into three sections. The section corresponding to the lower inner edge 26 is arc-shaped (lower section), the section corresponding to the rectangular section 25 is rectangular (middle section), and the upper inner edge 24 is arc-shaped (upper section). In an embodiment, each of the grain bottom augers 10 occupies a part of the upper section, the middle section, and the lower section, and the part of the upper section above the grain bottom auger 10 is the buffer section 23 mentioned in the above description.
[0051] In some other examples, the upper inner edge 24 can also be an arcuate curve with a continuously changing diameter.
[0052] According to the grain elevator provided by the embodiments of the present application, the axis of the grain bottom auger 10 can be displaced relative to the lower housing 30 assembly, so as to keep the gap between each part of the inner side of the grain bottom auger 10 and the grain inlet 21 relatively fixed during the process of conveying materials, thereby ensuring that the conveying state of the materials is relatively fixed and does not change with the position change of the grain bottom auger 10, which is beneficial to ensuring the smooth progress of material conveying.
[0053] According to the grain elevator provided by the embodiments of the present application, when observed along the axial direction, the ratio of the area of the grain inlet 21 to the area of the grain bottom auger 10 is 1.1 - 2.2.
[0054] See Figure 3 , Figure 3 The structural view of the grain elevator obtained by observing along the axial direction is shown in. Among them, the grain bottom auger 10 is circular, and the grain inlet 21 is in the shape of a waist-shaped hole as described above. The ratio of the area of the grain inlet 21 to the area of the grain bottom auger 10 is the area ratio as described above.
[0055] In the embodiment, the above area ratio characterizes the space occupied by the grain bottom auger 10 in the grain inlet 21. The larger the ratio of the area of the grain inlet 21 to the area of the grain bottom auger 10, the smaller the space occupied by the grain bottom auger 10 in the grain inlet 21. Conversely, the smaller the ratio of the area of the grain inlet 21 to the area of the grain bottom auger 10, the larger the space occupied by the grain bottom auger 10 in the grain inlet 21.
[0056] As an example, the above area ratio can be, for example, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1 or 2.2. As an example, the area ratio can also be, for example, 1.40, 1.41, 1.42, 1.43, 1.44 or 1.45.
[0057] In the embodiment, the above area ratio not only enables the grain bottom auger 10 to occupy a certain space in the grain inlet 21 to ensure stable conveying power for the material, but also leaves enough buffer section 23 between the grain bottom auger 10 and the grain inlet 21 to relieve the problems of material extrusion and easy blockage, which is beneficial to avoiding damage to the grain elevator, reducing the maintenance frequency of the grain elevator, and improving the reliability of the grain elevator.
[0058] According to the grain elevator provided by the embodiments of the present application, as described above, the grain elevator further includes a sprocket 40. The sprocket 40 can be sleeved on the outside of the part of the grain bottom auger 10 located inside the housing 30. The sprocket 40 is used for driving connection with an external driving structure, such as another sprocket 40 driven by a motor, through a chain, so as to drive the grain bottom auger 10 to rotate.
[0059] According to the grain elevator provided by the embodiments of the present application, as Figure 1As shown, the grain elevator may further include an intermediate housing portion 50 connected to the upper side of the housing 30, a chain rake 60 disposed inside the intermediate housing portion 50 for upwardly conveying materials, an elevator head 70 connected above the intermediate housing portion 50 and communicating with the intermediate housing portion 50, and a grain lifting cylinder 90 and a grain lifting auger 80. The grain lifting cylinder 90 is connected to the elevator head 70, and the grain lifting auger 80 is disposed inside the grain lifting cylinder 90 and is used for upwardly conveying materials. In the embodiment, the intermediate housing portion 50, the chain rake 60, the elevator head 70, the grain lifting auger 80, and the grain lifting cylinder 90 are all existing structures and will not be elaborated herein.
[0060] According to a second aspect of the embodiments of the present application, there is provided a grain conveying system. The grain conveying system includes the grain elevator as described above and also has the beneficial effects as described above, which will not be elaborated herein.
[0061] According to a third aspect of the embodiments of the present application, there is provided a harvester. The harvester includes the grain conveying system as described above and also has the beneficial effects as described above, which will not be elaborated herein.
[0062] The above are only the preferred embodiments of the present application, and thus do not limit the protection scope of the present application. Any equivalent structural transformation made by using the content of the specification and drawings of the present application under the innovative concept of the present application, or any direct / indirect application in other related technical fields is included in the protection scope of the present application.
