[0027] According to a first aspect of this utility model, a front suspension system is provided, such as... Figures 1 to 5 As shown, the front suspension system in this embodiment includes a base 1 and a tie rod assembly connected to the base 1. The tie rod assembly has multiple attachment points 24, which enable the tractor to simultaneously attach multiple different agricultural implements, thereby achieving combined tractor operations and effectively improving the tractor's operating efficiency. The specific connection and positional relationships of the various components of the front suspension system according to this invention will be described in detail below.

[0028] In this embodiment, as Figures 1 to 2 As shown, the base 1 has a first assembly part 11, a second assembly part 12 and a third assembly part 13, and the first assembly part 11, the second assembly part 12 and the third assembly part 13 are distributed in a triangular shape (that is, the line connecting the three forms a triangular shape, and the three are located at the three vertices of the triangle respectively), which can increase the stability of the overall structure of the front suspension system after the tie rod assembly is connected to the base 1.

[0029] Specifically, the first assembly part 11 is located at the center of the base 1 in the width direction and at the top of the front end face of the base 1; furthermore, the first assembly part 11 includes a first hanging plate 111 and a second hanging plate 112 extending in a direction away from the front end face, the first hanging plate 111 and the second hanging plate 112 being spaced apart along the width direction of the base 1, and the upper pull rod assembly 21 in the pull rod assembly is disposed between the first hanging plate 111 and the second hanging plate 112. More specifically, as Figure 3 As shown, the upper pull rod assembly 21 includes an adjusting screw 211 and a sleeve 212 correspondingly sleeved on the outer side of the adjusting screw 211. The first end of the adjusting screw 211 in the length direction can be connected to the first assembly part 11, and the second end of the adjusting screw 211 in the length direction forms a hook part 24.

[0030] Furthermore, such as Figures 3 to 5 As shown, the first end of the upper pull rod assembly 21 is equipped with a locking pin assembly 214. Correspondingly, the first mounting plate 111 and the second mounting plate 112 form locking pin holes 113 corresponding to the locking pin assembly 214. That is, the upper pull rod assembly 21 and the first assembly part 11 can be connected through the locking pin assembly 214 and the locking pin holes 113. Similarly, the first end of the upper pull rod assembly 21 is also equipped with a round shaft. Correspondingly, the first mounting plate 111 and the second mounting plate 112 form round shaft holes 114 corresponding to the round shaft. In addition, the first mounting plate 111 also forms a first threaded hole 115, which is correspondingly provided with a bolt assembly.

[0031] When the upper pull rod assembly 21 is assembled with the base 1, the ball end of the first end of the upper pull rod assembly 21 is positioned between the first mounting plate 111 and the second mounting plate 112, with the center hole of the ball end corresponding to the round shaft hole 114. Then, the round shaft is assembled with the round shaft hole 114 and the center hole of the ball end. In this embodiment, a baffle 116 is welded to the end of the round shaft. After the round shaft is assembled, it is rotated so that the second threaded hole of the baffle 116 corresponds to the first threaded hole 115. Then, the second threaded hole and the first threaded hole 115 are connected by a bolt assembly. This prevents the round shaft (and the baffle 116) from moving, ensuring the stability of the upper pull rod assembly 21. That is, the baffle 116 facilitates the improvement of the stability of the assembly of the upper pull rod assembly 21 with the base 1.

[0032] When the upper tie rod assembly 21 is not in use (i.e., when the upper tie rod assembly 21 is not in operation), the upper tie rod assembly 21 can be locked to the base 1 by the locking pin assembly 214 to prevent the upper tie rod assembly 21 from shaking and affecting the overall structural stability of the front suspension system.

[0033] It should be noted that the above-mentioned structures of the upper pull rod assembly 21 (such as the adjusting screw 211, sleeve 212, locking pin assembly 214, and rotating shaft) are all prior art. In addition, the specific connection method between the locking pin assembly 214 and the first assembly part 11, its locking principle, and the specific implementation method of the rotatable connection between the round shaft and the round shaft hole 114 are also prior art and will not be described in detail. In particular, the upper pull rod assembly 21 in this embodiment also includes two locking members 213 correspondingly sleeved on the outer side of the adjusting screw 211. The two locking members 213 are respectively disposed at both ends of the extension direction of the sleeve 212. The two locking members 213 can prevent the sleeve 212 from shaking and displacing (relative to the adjusting screw 211) after the upper pull rod assembly 21 is attached to the agricultural machinery. That is, the two locking members 213 can limit the extension direction of the sleeve 212.

[0034] In addition, such as Figures 1 to 2As shown, the base 1 has pins extending towards the top surface away from the base 1 at both ends in the width direction. The two pins respectively form a second assembly part 12 and a third assembly part 13. The first pull rod assembly 22 in the pull rod assembly is rotatably connected to the second assembly part 12, and the second pull rod assembly 23 in the pull rod assembly is rotatably connected to the third assembly part 13. The ends of the first pull rod assembly 22 and the second pull rod assembly 23 away from the base 1 have hook-on parts 24 for attaching agricultural implements. It should be noted that the first pull rod assembly 22 and the second pull rod assembly 23 are existing components, and their specific connection methods with the base 1 are also existing technology, therefore they will not be described in detail. Similarly, the specific structures of the second assembly part 12 and the third assembly part 13 will not be described in detail either; they only need to be able to connect correspondingly to the first pull rod assembly 22 and the second pull rod assembly 23.

[0035] Furthermore, in this embodiment, the base 1 also has an assembly cavity 14, which extends through the rear end face, top end, and bottom end of the base 1, forming a semi-enclosed structure. The hydraulic cylinder is correspondingly disposed in the assembly cavity 14, and the base 1 can protect the hydraulic cylinder. As shown in the figure, the hydraulic cylinder is connected to the first pull rod assembly 22 and the second pull rod assembly 23, so as to drive them to rotate relative to the base 1.

[0036] Furthermore, the base 1 in this embodiment also has other assembly structures for integrating components such as sockets and control buttons into one unit. These will not be elaborated further and can be determined according to the actual situation. Based on the above technical effects, it is preferable to set the base 1 as a casting.

[0037] In this embodiment, as Figures 4 to 5 As shown, the base 1 is also equipped with a towing seat 15. When the tractor gets stuck, a towing rope can be attached to the towing seat 15 to help the vehicle get out of trouble. In addition, towing plates 16 are screwed to both ends of the base 1 in the width direction. The towing plates 16 have multiple attachment holes, so when the tractor is moving on the road or in the field (when the tractor is not working), the free end of the chain of the agricultural implement can be connected to the attachment holes of the towing plate 16. This can fix and protect the agricultural implement, and can distribute the weight borne by the first lower lever assembly 22 and the second lower lever assembly 23 to prevent the first lower lever assembly 22 and the second lower lever assembly 23 from sinking due to the excessive weight of the agricultural implement.

[0038] According to the front suspension system described above, a first assembly part 11, a second assembly part 12, and a third assembly part 13 are provided on the base 1 of the front suspension system. These three parts are respectively connected to the upper pull rod assembly 21, the first lower pull rod assembly 22, and the second lower pull rod assembly 23. Different agricultural implements can be attached to the upper pull rod assembly 21, the first lower pull rod assembly 22, and the second lower pull rod assembly 23 (via their attachment parts 24). This effectively improves the usability of the front suspension system, allowing the tractor to simultaneously attach multiple different agricultural implements for combined operations, thereby significantly improving the tractor's operating efficiency. Furthermore, the aforementioned attachment parts 24 can also be used to attach counterweights to improve the tractor's stability.

[0039] According to a second aspect of the present invention, a tractor is provided, wherein the tractor includes a front suspension device as described above.

[0040] 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.
