Detailed implementation manners

[0021] The following will make a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0022] The following will describe in detail the embodiments of the present invention. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0023] Embodiment: As Figures 1 to 4 shown, a traction device for a walk-behind tractor includes a mounting frame 50, a towing frame 51, a rotating frame 58, a connecting frame 59 and a tow hook 510. The above mounting frame 50 is fixedly installed on the vehicle body through locking members such as locking bolts. The above towing frame 51 is installed on the above mounting frame 50. The above towing frame 51 is provided with a fixed shaft 513. One end of the above rotating frame 58 is rotatably installed on the above fixed shaft 513. The above connecting frame 59 is sleeved outside the above rotating frame 58. The above tow hook 510 is installed at one end of the above connecting frame 59. By adjusting the position of the connecting frame 59 on the rotating frame 58, the distance between the tow hook 510 and the mounting frame 50 can be changed, that is, the tow hook 510 can be extended or shortened. In the case of no towing rope, the position change of the tow hook 510 can be skillfully realized, so that the tow hook 510 and the goods can also realize the traction function of the tractor without a pulling rope, expanding the applicable range of the tractor, which is beneficial to the popularization and application of the above traction device on the walk-behind tractor.

[0024] A rotating frame hole 580 is provided along the length direction of the above rotating frame 58, and a connecting frame hole 590 is provided along the length direction of the above connecting frame 59. The above connecting frame hole 590 is adaptively arranged with the above rotating frame hole 580, and the position fixation between the above connecting frame 59 and the above rotating frame 58 is realized by passing a positioning member 511 through the above connecting frame hole 590 and the above rotating frame hole 580. The length of the tow hook 510 is adjusted by adjusting the positions of the rotating frame 58 and the connecting frame 59.

[0025] In this embodiment, the rotating frame holes 580 are set to six, and the connecting frame holes 590 are set to three. When the rotating frame holes 580 at the upper end of the rotating frame 58 correspond to the connecting frame holes 590 at the head end of the connecting frame 59, at this time, the distance between the towing hook 510 and the mounting frame 50 is the farthest.

[0026] The positioning member 511 can be a positioning bolt or a positioning screw with a simple structure, convenient installation and wide application, which can effectively improve the disassembly and assembly efficiency, and thus improve the working efficiency of the walking tractor.

[0027] In order to further expand the applicable range of the tractor and realize the change of the position of the towing hook 510 in height, a plurality of mounting frame holes 500 are provided along the longitudinal direction of the above-mentioned mounting frame 50. The longitudinal direction is the height direction. The towing frame 51 is provided with towing frame holes 501. The towing frame holes 501 are adapted to the mounting frame holes 500, and the position between the mounting frame 50 and the towing frame 51 is fixed by passing a positioning member 511 through the towing frame holes 501 and the mounting frame holes 500. By moving the towing frame 51 up or down on the mounting frame 50, the change of the position of the towing hook 510 in height is realized, and the applicable range of the tractor is further expanded.

[0028] In order to ensure the stability of the rotating frame 58 and the above-mentioned connecting frame 59 during use, and thus ensure the stability of the towing hook 510 during the process of towing goods and ensure its use effect, both the rotating frame 58 and the connecting frame 59 are square tube structures.

[0029] To facilitate the installation of the fixed shaft 513, a first ear plate 53 and a second ear plate 512 are fixedly arranged on the towing frame 51. The fixed shaft 513 is fixedly arranged between the first ear plate 53 and the second ear plate 512 to ensure the stability of the structure of the fixed shaft 513. A sleeve is welded at one end of the rotating frame 58, and the sleeve is sleeved outside the fixed shaft 513 to realize the rotation of the rotating frame 58 around the fixed shaft 513, thereby driving the towing hook 510 and realizing the change of the direction of the towing hook 510.

[0030] In order to further ensure the use effect of the towing hook 510 and enhance the user experience, this embodiment further includes a torsion spring 57 for straightening the above-mentioned rotating frame 58. A third ear plate 52 is provided near the upper end face of the above-mentioned towing frame 51. A pin shaft 54 is installed between the first ear plate 53 and the third ear plate 52. A first straightening column 56 is installed on the rotating frame 58. The main body of the torsion spring 57 is sleeved on the pin shaft 54, and the end of the torsion spring 57 is buckled on the first straightening column 56. In the specific manufacturing and installation process, in order to reduce the installation difficulty, the pin shaft 54 and the fixed shaft 513 can be set as the same shaft, and mounting holes are provided on the first ear plate 53, the second ear plate 512 and the third ear plate 52 to facilitate the installation of this shaft and ensure the stability of this shaft during the installation process.

[0031] To ensure the usage effect, the above-mentioned first alignment post 56 is arranged at the central axis position of the above-mentioned rotating frame 58. A second alignment post 55 is also provided between the above-mentioned first ear plate 53 and the above-mentioned third ear plate 52. The second alignment post 55 serves to support the torsion spring 57. Both the above-mentioned second alignment post 55 and the above-mentioned first alignment post 56 are arranged in a cylindrical structure.

[0032] As Figure 4 shown, the installation schematic diagram of the traction device in this embodiment installed on a walking tractor is shown at position A.
