[0022] The following specific embodiments are provided to assist the reader in obtaining a comprehensive understanding of the methods, apparatuses, and / or systems described herein. However, after understanding the disclosure of this application, various changes, modifications, and equivalents of the methods, apparatuses, and / or systems described herein will be apparent. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, changes that will be apparent after understanding the disclosure of this application may be made, except for operations that must occur in a specific order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0023] The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, apparatuses, and / or systems described herein that will be apparent after understanding the disclosure of this application.

[0024] Throughout the specification, when an element (such as, a layer, region, or substrate) is described as "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it may be directly "on," "connected to," "coupled to," "above," or "covering" the other element, or there may be one or more other elements intervening therebetween. In contrast, when an element is described as "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there may be no other elements intervening therebetween.

[0025] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0026] Although terms such as "first," "second," and "third" may be used herein to describe various components, elements, regions, layers, or portions, these components, elements, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or portion from another. Thus, the first component, element, region, layer, or portion described in the examples herein may also be referred to as the second component, element, region, layer, or portion without departing from the teachings of the examples.

[0027] For ease of description, spatial relationship terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another as shown in the accompanying drawings. Such spatial relationship terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is flipped, an element described as "above" or "upper" relative to another element will then be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientation of "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

[0028] The terms used herein are for the purpose of describing various examples only and are not intended to limit the disclosure. Unless the context clearly dictates otherwise, the singular forms are also intended to include the plural forms. The terms "comprises", "comprising", and "having" list the stated features, quantities, operations, components, elements, and / or combinations thereof that exist, but do not preclude the existence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0029] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the accompanying drawings may occur.

[0031] According to a first aspect of the present utility model, a grain elevator is provided, as Figures 1 to 2 shown. The grain elevator in this embodiment includes a barrel 1 and a lifting device connected to the barrel 1. The barrel 1 can be flexibly and precisely controlled to extend or retract through the lifting device. Hereinafter, the specific structures of the above-mentioned various parts of the grain elevator according to the present utility model will be described in detail.

[0032] In this embodiment, as Figure 1As shown in the figure, the lifting device includes a telescopic part connected to the cylinder body 1 and a driving part connected to the telescopic part. The driving part drives the telescopic part to drive the cylinder body 1 to extend or retract synchronously. Specifically, in this embodiment, the telescopic part is provided with a first connecting rod 11 and a second connecting rod 12 connected in sequence. The first end of the first connecting rod 11 is connected to the grain box 4, and the second end of the second connecting rod 12 is connected to the above-mentioned cylinder body 1. Further, as Figure 1 shown, the first end of the first connecting rod 11 is connected to the grain box 4 through a connecting seat 13, that is, the connecting seat 13 is fixed to the bottom of the grain box 4 by welding or screwing, etc. The first end of the first connecting rod 11 is fixed to the connecting seat 13 by welding to facilitate improving the stability when the cylinder body 1 moves.

[0033] It should be noted that the shape, size of the connecting seat 13 and its connection position with the grain box 4 are not fixed, and should be determined comprehensively according to actual situations such as the specifications of the grain lifting cylinder and the grain box 4, as long as it can facilitate the stable lifting of the cylinder body 1 (the extension of the cylinder body 1 is the rise, and the retraction of the cylinder body 1 is the fall).

[0034] In addition, as Figure 1 shown, the second end of the second connecting rod 12 is connected to the cylinder body 1 through a fixing seat 14. The fixing seat 14 is formed into an annular structure corresponding to the cylinder body 1 and sleeved on the outer side of the cylinder body 1. In this embodiment, the second end of the second connecting rod 12 is connected to the fixing seat 14 by welding to facilitate improving the stability when the cylinder body 1 moves. It should be noted that the connection position between the fixing seat 14 and the cylinder body 1 is not fixed, and the connection method between the two is not fixed either (for example, the connection stability can be ensured by welding or interference fit, etc.).

[0035] Further, the second end of the first connecting rod 11 and the first end of the second connecting rod 12 are rotatably connected through a rotating shaft (or the rotating connection between the two can also be realized through structures such as hinges). Their shapes, specifications, etc. can be determined comprehensively according to actual situations such as the positional relationship between the cylinder body 1 and the grain box 4. In this embodiment, the driving part is formed into an electric push rod 15 (the driving part can also be an oil cylinder or a gear box and other components that can provide power, as long as the above technical effects can be achieved). The telescopic end of the electric push rod 15 is connected to the rod body of the second connecting rod 12, and its fixed end can be fixed to the grain box 4; when the telescopic end of the electric push rod 15 extends or retracts, the second connecting rod 12 rotates relative to the first connecting rod 11, thereby driving the cylinder body 1 to extend or retract.

[0036] It should be noted that the number of connecting rods included in the telescopic part is not fixed either, and can be flexibly determined according to actual situations. When the number of connecting rods is multiple, the multiple connecting rods are rotatably connected in sequence.

[0037] According to the grain lifting cylinder of the present utility model, the operation of the cylinder body 1 is controlled by setting a lifting device. The lifting device includes a telescopic part (which is composed of a plurality of link rods rotatably connected in sequence) connected to the cylinder body 1 and a driving part. The driving part can drive the link rods to rotate, and then the link rods drive the cylinder body 1 to lift and lower synchronously. In this way, the grain lifting cylinder can be driven simply and smoothly, and the safety factor is relatively high when the grain lifting cylinder is operating.

[0038] According to the second aspect of the present utility model, a conveyor is provided. The conveyor includes the grain lifting cylinder, the housing 2, the grain lifting device 3 and other components as described above. The connection methods and structures of the above components all belong to the prior art, so they will not be elaborated here.

[0039] According to the third aspect of the present utility model, a harvester is provided. The harvester includes the conveyor as described above.

[0040] Finally, it should be noted that: the above embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed in the present application can still modify the technical solutions recorded in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
