Problems solved by technology

[0002] At present, most of the transportation methods of tractors use single-car operation, and a few use one-back-one-way transportation. This method is to connect the longitudinal beam of the second tractor to the first tractor by means of skids, wire ropes and clips. There are many shortcomings and deficiencies in the above-mentioned transportation methods, which are specifically manifested in: ①The single-vehicle operation mode has caused a lot of waste of manpower and financial resources, especially energy waste; ②One-back-one-way transportation is not safe. Reliable, low work efficiency, fuel consumption

Abstract

The invention relates to a rear traction device for a second tractor to draw a third tractor of a tractor with a one-traction-two mode. The rear traction device comprises a welded base plate, a modified traction seat assembly and a connecting device; the welded base plate is arranged below the modified traction seat assembly; and the connecting device is arranged above the modified traction seat assembly. As the connecting device adopts a groove type composite structure and is reliably coupled with a traction seat of a molded product, the bearing surface is large; the surface of the traction seat is provided with a lube groove; the addition of lube reduces the abrasion between the surface of a seat plate and the surface of a connecting body; and the rear traction device has the advantages of simple structure, good safety, wide range of application, low processing cost, and the like, realizes the one-traction-two operation mode of the tractor and fills up one blank of the state.

Description

technical field [0001] The invention relates to a rear traction device for the second tractor to tow the third tractor in the operation mode of one tractor with two tractors, which can reliably couple the towed second tractor and the third tractor to achieve The tractor is towed by the tractor and driven safely. Thereby realizing the operation mode of tractor one dragging two. Background technique [0002] At present, most of the transportation methods of tractors use single-car operation, and a few use one-back-one-way transportation. This method is to connect the longitudinal beam of the second tractor to the first tractor by means of skids, wire ropes and clips. There are many shortcomings and deficiencies in the above-mentioned transportation methods, which are specifically manifested in: ①The single-vehicle operation mode has caused a lot of waste of manpower and financial resources, especially energy waste; ②One-back-one-way transportation is not safe. Reliable, low ...
