Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery traction, and more specifically, to an agricultural machinery traction device. 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 treatment of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilizing machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transport machinery, etc. When in use, agricultural machinery usually needs to be connected to a tractor through a traction device;

[0003] After searching, the existing patent (publication number: 201921665118.0) discloses an agricultural machinery traction device, which relates to the field of agricultural machinery technology, including a connecting piece, the upper surface of which is fixedly connected to two symmetrical first traction rods, the outer surface of each first traction rod top is provided with a first fixing hole, the upper surface of the connecting piece is fixedly inlaid with a positioning tube, the interior of the positioning tube is sleeved with a positioning rod, the top of the positioning rod is fixedly connected with a pull plate, the left and right sides of the pull plate are fixedly inlaid with threaded tubes, and the side of the two first traction rods close to each other are provided with threaded holes arranged at equal distances. The utility model has a reasonable design structure, and can be driven by the staff to pull the pull plate according to the model of the agricultural machinery to drive the positioning rod and the rack to move, and drive the rotating rod and the second traction rod to rotate under the action of the teeth, and fix it with the agricultural machinery through the second fixing hole, and insert the threaded rod into the threaded hole and the inside of the threaded tube for fixing, so as to avoid the need to carry a variety of traction parts when operating agricultural machinery, thereby improving its applicability.

[0004] Most of the existing agricultural machinery traction devices fix the agricultural machinery and the tractor by means of latches. When moving, the latches are easy to fall off due to the shaking of the vehicle body, resulting in the inability to tow the agricultural machinery. At the same time, when the tractor stops, the agricultural machinery will also generate forward inertia. Most of the current agricultural machinery traction devices do not have a buffer device, so their protection performance is poor.
