Description

Technical Field

[0001] The utility model relates to the technical field of baler traction, in particular to a baler traction device. Background Art

[0002] A baler refers to a machine used to bale grass. It is divided into hydraulic balers and tractor-trailer balers. From the perspective of raw materials, it is divided into corn straw balers, wheat straw balers, rice straw balers, flax balers, etc. From the shape of the finished product, it is divided into square bale balers and round bale balers. When a tractor-trailer baler is working, the traction device needs to provide the traction required for walking.

[0003] However, there are still some problems in the specific use of the existing baler traction device: the structure of the existing baler traction device is mostly fixed, and the height adjustment of the baler is achieved through the lifting mechanism of the tractor. Since the lifting mechanism of the tractor is mostly arc-shaped, the height of the baler cannot be adjusted vertically during use, and the existing baler traction device cannot protect the pin shaft. When the pin shaft breaks, the baler will be separated from the tractor, which will cause the hydraulic pipelines between the two to be torn off. Utility Model Content
