DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figures 1 to 4 The utility model provides a technical solution: an agricultural machinery traction device, including an agricultural machinery mounting seat 1, the agricultural machinery mounting seat 1 is an "L"-shaped structure, a rotating seat 2 is welded on one side of the agricultural machinery mounting seat 1, a rotating shaft 5 is rotatably connected to the rotating seat 2, a rotating bar 3 is welded on the rotating shaft 5, and a traction hook 4 is welded on the end of the rotating bar 3. The rotation of the rotating shaft 5 drives the rotating bar 3 and the traction hook 4 to rotate, which is convenient for adjusting the angle of the traction device.
[0021] An adjusting handle 6 is welded to the end of the rotating shaft 5, and a limit assembly is provided on the adjusting handle 6 for easy rotation adjustment. The limit assembly includes a movable plug 61. A groove is provided on the adjusting handle 6, and the movable plug 61 is slidably inserted into the groove. An abutment spring 62 is fixedly connected between the movable plug 61 and the groove. The model of the abutment spring 62 can be selected according to actual working conditions.
[0022] An annular block 7 is welded to one side of the rotating seat 2, and a slot 71 is opened in the circumference of the annular block 7. The end of the movable plug-in block 61 is inserted into the slot 71, and an elastic plug-in structure is formed between the abutment spring 62 and the movable plug-in block 61, so that the end of the movable plug-in block 61 is inserted into the corresponding slot 71. Even if there is shaking, the end of the movable plug-in block 61 can be inserted into the slot 71 without being detached.
[0023] The hook portion of the traction hook 4 is provided with a stopper for easy adjustment, and the stopper includes a pulling shaft 8. A receiving groove is provided on the hook portion of the traction hook 4, and a fixing block 81 is fixed at the opening of the receiving groove by bolts. The pulling shaft 8 is slidably inserted into the fixing block 81, and a stopper 83 is welded on the end portion of the pulling shaft 8. A support spring 82 is sleeved on the pulling shaft 8, and the end face of the stopper 83 abuts against the side of the rotating bar 3.
