[0027] According to a first aspect of this utility model, a front-loading boom structure is provided, such as... Figures 1 to 2As shown, the front-loading boom structure is assembled from two support arms 1 and a crossbeam 2. The two support arms 1 have identical structures and are symmetrically distributed at both ends of the crossbeam 2 in the extension direction to ensure the stability of the structure. The specific structure and positional relationships of the aforementioned components of the front-loading boom structure in this embodiment will be described in detail below.
[0028] In this embodiment, as Figure 1 As shown, the support arm 1 includes a front arm 11 and a rear arm 12, which are assembled correspondingly via connecting components. The rear arm 12 is connected to the second end of the front arm 11 in the extension direction. Specifically, the front arm 11 is welded from a bending plate 111 and a flat plate 112, and the weld between the bending plate 111 and the flat plate 112 is located on the inner side of the support arm 1 near the crossbeam 2. This makes the weld relatively concealed, which helps to improve the aesthetics of the front loading boom structure.
[0029] Furthermore, such as Figure 2 As shown, the bent plate 111 in this embodiment includes a first connecting plate, a second connecting plate, and a third connecting plate connected in sequence. The first and third connecting plates are parallel and both are perpendicular to the second connecting plate, so that the cross-section of the bent plate 111 is formed into a U-shaped structure, that is, the bent plate 111 has a first opening facing the second connecting plate. The flat plate 112 is adapted to the second opening, and the two ends of the flat plate 112 are respectively welded to the ends of the first connecting plate away from the second connecting plate and the ends of the third connecting plate away from the second connecting plate. In this way, the weld between the bent plate 111 and the flat plate 112 is located at the edge of the inner side of the forearm 11, further improving the concealment of the weld.
[0030] Furthermore, in this embodiment, the connection between the crossbeam 2 and the support arm 1 is actually a corresponding connection with the forearm 11. For example... Figure 2 As shown, in each forearm 11, the plate 112 and the second connecting plate are respectively formed with a first through hole 116 and a second through hole 117. The end of the crossbeam 2 is inserted into the first through hole 116 and the second through hole 117 and welded to the forearm 11 accordingly.
[0031] In addition, the forearm 11 is also provided with a limiting part. For example... Figures 1 to 2As shown, the limiting part includes a limiting block 113, which is welded to the outer surface of the third connecting plate and located at the first end of the forearm 11 along its extension direction. When this boom structure is assembled with the corresponding front-loading assembly, the limiting block 113 can limit the bucket after material collection. Furthermore, the limiting part includes a limiting plate 114, which is welded to the end face of the first end of the forearm 11 to close the opening at the first end of the forearm 11. After the limiting plate 114 is welded to the forearm 11, it protrudes from the outer surface of the forearm 11 to limit the bucket during unloading. It should be noted that the specifications of the limiting block 113 and the limiting plate 114 are not specifically limited and can be determined according to the actual situation, such as the specifications of the corresponding assembly. The corresponding assembly will not be described further, as it is an inherent structure of existing front-loading systems.
[0032] In addition, the forearm 11 is welded with a plurality of fixing parts 115 for assembling corresponding components (the components being pre-loaded inherent components).
[0033] In this embodiment, as Figure 1 As shown, the connecting assembly includes a first connector 131, which is configured according to the required structure of the support arm 1. Its two ends are welded to the forearm 11 and the rear arm 12, respectively. That is, the specific structure of the first connector 131, such as its bending angle, is not specifically limited and should be determined according to the actual situation, as long as it can stably connect the forearm 11 and the rear arm 12, so that the overall structure of the support arm 1 meets the stability and assembly requirements of the pre-assembly structure. To further improve the overall stability of the support arm 1, the connecting assembly also includes two second connectors 132, which are welded to the two facing end faces of the support arm 1 (specifically, welded to the forearm 11 and the rear arm 12), and further fixed by components such as bolts.
[0034] Furthermore, in this embodiment, such as Figure 1 As shown, the rear arm 12 is formed into an arc-shaped structure, which can be formed by bending a rectangular tube, resulting in a lower cost.
[0035] According to the front loading boom structure described above, the front loading boom structure includes two support arms 1 and a crossbeam 2. The two support arms 1 are symmetrically arranged at both ends of the crossbeam 2. The support arm 1 includes a forearm 11. The forearm 11 in this invention is formed by welding a bending plate 111 and a flat plate 112. The weld between the two is located on the inner side of the support arm 1 near the crossbeam 2. Compared with the weld formed by two bending plates 111 in the prior art, the weld of this structure is more concealed, which effectively improves the aesthetics of the front loading boom. In addition, the welding of the flat plate 112 and the bending plate 111 (compared to welding two bending plates 111) is less difficult, which can effectively ensure the welding quality, thereby ensuring the manufacturing quality of the boom.
[0036] According to a second aspect of the present invention, a tractor is provided, the tractor including the front-loading boom structure as described above.
[0037] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be defined by the protection scope of the claims.
