[0016] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0017] Please refer to Figures 1-4 This utility model provides a modular quick-release tractor sleeve assembly, including a connecting cylinder 1. The opening end of the connecting cylinder 1 has a slot 100, and the slot 100 contains an installation module 14 for connection with the tractor. A locking mechanism 2 is provided on the outside of the slot 100, and the locking mechanism 2 is used to lock the connecting cylinder 1 and the installation module 14. The locking mechanism 2 includes a fixing block 20 fixedly connected to the connecting cylinder 1, and a fixing shaft 21 is fixedly provided on the inside of the fixing block 20. A clamping plate 22 is rotatably provided on the outside of the fixing shaft 21, and a limit hole is provided on the clamping plate 22. A locking component 23 is provided on the inside of the limit hole, and the locking component 23 cooperates with the limit hole to lock the clamping plate 22. The connecting cylinder 1 accommodates the installation module 14 through the slot 100 at its opening end. The locking mechanism 2 located on the outside of the slot 100 realizes mechanical locking and releasing of the installation module 14 connected to the slot 100 through the rotatable clamping plate 22 and the locking component 23 thereon.

[0018] like Figure 2 As shown, the mounting module 14 includes a mounting post 140 that is fixedly connected to the tractor, and the mounting post 140 is integrally connected to an extension plate 141. Both sides of the extension plate 141 are integrally connected to recesses 142, and the distance between the outer sides of the two recesses 142 is greater than the outer diameter of the connecting cylinder 1. The mounting post 140 is provided with a through fixing hole, and the fixing hole is used to fix the mounting module 14 to the tractor by bolts or pins. As the part that is fixed to the tractor, the recesses 142 on both sides of the extension plate 141 of the mounting module 14 are used to be embedded in the slots 100 of the connecting cylinder 1 for radial positioning, while the fixing hole on the mounting post 140 is axially fixedly connected to the tractor body by bolts or pins.

[0019] A mounting rod 10 is fixedly installed on one side of the connecting cylinder 1, and a connecting arm 11 is hinged to the outside of the mounting rod 10. An extension rod 12 is hinged to the end of the connecting arm 11 away from the mounting rod 10, and an installation part 13 for connecting to an external agricultural tool is hinged to the end of the extension rod 12 away from the connecting arm 11. The side of the connecting cylinder 1 forms a multi-stage hinged linkage mechanism through the mounting rod 10, the connecting arm 11, the extension rod 12 and the installation part 13. The linkage mechanism allows the end installation part 13 to make multi-degree-of-freedom spatial position and angle adjustments under the action of external force.

[0020] To improve service life, the surfaces of the connecting cylinder 1, mounting rod 10, connecting arm 11, extension rod 12, and mounting component 13 are all coated with anti-corrosion paint.

[0021] like Figure 4 As shown, the locking assembly 23 includes a support block 230, and a connecting post 231 is fixedly provided on one side of the support block 230. A spring piece 232 is fixedly provided at one end of the connecting post 231, and a conical locking block 233 is fixedly provided at the end of the spring piece 232 away from the connecting post 231. Several spring pieces 232 are provided, and the several spring pieces 232 are arranged in a circumferential array along the axial direction of the connecting post 231. When locking, the clamping plate 22 is operated to align the limiting hole on it and fit onto the locking assembly 23. The circumferential array of spring pieces 232 and the conical locking block 233 at its end undergo elastic deformation when squeezed by the inner wall of the limiting hole. Once the conical locking block 233 completely passes through the limiting hole, the spring piece 232 rebounds and the conical surface reverses to lock against the hole wall, realizing self-locking.

[0022] In summary, when installing this modular quick-release tractor sleeve assembly, the installation module 14 is pre-fixed to the tractor via its mounting post 140. During attachment, the slot 100 at the front end of the connecting cylinder 1 is aligned with and engaged with the recesses 142 on both sides of the installation module 14 to achieve initial positioning. Subsequently, the clamping plate 22 of the locking mechanism 2 is rotated so that its limiting hole fits into the locking component 23. Under the guidance of the conical locking block 233 and the elastic deformation-rebound action of multiple spring pieces 232, the locking component 23 automatically engages with the limiting hole to achieve self-locking, thereby firmly locking the connecting cylinder 1 and the installation module 14 into one unit. When it is necessary to change the agricultural implement, simply apply a reverse force to the locking component 23 to quickly unlock and separate the connecting cylinder 1. At the same time, the mounting rod 10, connecting arm 11, and extension rod 12 hinged to the connecting cylinder 1 allow the end mounting piece 13 to flexibly adjust the posture of the agricultural implement to adapt to different operational needs.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
