[0035] The following detailed embodiments are provided to aid the reader in gaining a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein, but rather, changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted. The features described herein may be implemented in different forms and should not be construed as being 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, apparatus, and / or systems described herein that will be apparent after understanding the disclosure of this application. Throughout this specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. Conversely, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between. As used herein, the term "and / or" includes any one of the relevant items listed and any combination of any two or more of them. Although terms such as "first," "second," and "third" may be used herein to describe individual components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. More precisely, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as such in the examples may also be referred to as the second component, assembly, region, layer, or part. For ease of description, spatial relational terms such as “above,” “upper,” “below,” and “lower” may be used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relational terms are intended to include not only the orientation depicted in the drawings but also the different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element.Therefore, the term "above" includes both "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 relational terms used herein will be interpreted accordingly. The terminology used herein is for describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "comprising," "including," and "having" enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof. Variations in the shapes shown in the figures may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the figures but include changes in shape that occur during manufacturing. The features of the examples described herein may be combined in various ways that will be apparent upon understanding the disclosure of this application. Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible as will be apparent upon understanding the disclosure of this application.

A contour groove 52 corresponding to the position and size of the limiting pin 22 is provided on the connecting part 51, so that the contour groove 52 of the bumper connector 5 can overlap the limiting pin 22.

[0042] like Figure 4 and Figure 5 As shown, a mounting hole 23 is provided on the bumper mounting base 2, and a sleeve 53 is provided on the bumper connector 5 through the connecting part 51. When the contour groove 52 overlaps with the limiting pin 22, the sleeve 53 can be positioned opposite to the mounting hole 23.

[0043] The locking assembly 4 includes a bumper anti-rotation shaft 41, which can pass through the sleeve 53 and be inserted into the mounting hole 23, thereby keeping the front bumper frame 3 and the bumper mounting base 2 relatively fixed.

[0044] The sleeve 53 has a first through hole 54 on its wall, and the central axis of the first through hole 54 is perpendicular to the central axis of the sleeve 43. The bumper anti-rotation shaft 41 has a second through hole 42, and the locking pin 12 can pass through the first through hole 54 and the second through hole 42, thereby fixing the bumper anti-rotation shaft 41 to the bumper connector 5, so that the bumper anti-rotation shaft 41 will not fall out of the sleeve 53.

[0045] A pull ring is also provided on the locking pin 12 to facilitate pulling the locking pin 12 out of the first through hole 54 and the second through hole 42.

[0046] In a more preferred embodiment, a limiting member may also be provided on the bumper ear seat 11 to limit the maximum position of the front bumper frame 3 when it is flipped, that is, to make the front bumper frame 3 stay in the first position after it is flipped.

[0047] In a preferred embodiment, a license plate 6 is also provided on the front bumper frame 3 for the tractor to install a license plate.

[0048] In a preferred embodiment, the mounting bracket 1 can be a separate mounting bracket for attaching the entire rotatable bumper to the tractor. It can also provide connection and securing positions for other tractor components requiring mounting.

[0049] The mounting bracket 1 can also be directly replaced by the tractor's bracket, chassis, or even the engine cover.

[0050] This embodiment also provides a tractor, including the aforementioned rotatable bumper mounted at the front of the tractor.

[0051] When the front bumper frame needs to be opened, simply pull out the locking pin to flip the front bumper frame relative to the fixed frame, thereby exposing the tractor hood for easy inspection and maintenance.

[0052] When closing the front bumper frame, simply flip the front bumper frame up around the pin shaft, let the contour groove lock onto the limit pin, and then insert the bumper anti-rotation shaft and locking pin to lock and fix the front bumper frame.

[0053] The front bumper frame is easy to flip and fix, quick and easy to operate, and the positioning is reliable.

[0054] 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.
