Description

Technical Field

[0001] The utility model relates to the field of traction devices, and more specifically, to a traction device for agricultural machinery. Background Art

[0002] Agricultural machinery refers to various machines used in the production process of crop planting and animal husbandry, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transport machinery, etc. In the daily work of farmers, agricultural machinery is generally used to provide power and to pull agricultural tools (such as sleds, tillers, etc.) to carry out construction work on the land. Agricultural tools and agricultural machinery are generally connected by traction devices;

[0003] After searching, the existing patent (Announcement No.: CN219205177U) discloses a traction device for agricultural machinery, which belongs to the field of agricultural machinery traction technology. An anti-slip mechanism is provided on the connecting frame 1, and the anti-slip mechanism is used in conjunction with a latch. The connecting frame 1 is provided with a groove, and through holes 1 are provided on both sides of the groove. A through hole 2 is provided on the connecting frame 2, and the through hole 2 is provided between the two through holes 1. The latch slides through the through hole 1 and the through hole 2 respectively. A telescopic mechanism is provided at both ends of the connecting frame 1, and the telescopic mechanism is slidably connected with the connecting frame 2. A limiting mechanism is provided at the lower end of the connecting frame, and the limiting mechanism is used in conjunction with the lower end of the latch. The utility model wraps the upper end of the latch through the anti-slip mechanism, which effectively avoids the problem that the latch is easy to fall off due to the bumping and shaking of the vehicle body during movement. At the same time, the lower end of the latch is limited for a second time by the limiting mechanism, which better improves the limiting effect. The two telescopic mechanisms work alternately when turning, which reduces the pulling force and inertia generated when turning, and better protects the service life of the traction mechanism.

[0004] The existing agricultural machinery traction device requires manual assembly, which is cumbersome. The rotation angle after assembly is single, which is not flexible enough to drive the agricultural implements to move. In addition, when the front vehicle body stops, the agricultural implements towed by the rear will move forward due to inertia, which may easily cause damage to the migration mechanism, thereby reducing the use effect. At the same time, the above-cited patent documents do not propose relevant solutions to solve the above problems.

[0005] Therefore, in order to solve the above problems, a traction device for agricultural machinery is proposed. Utility Model Content
