Description

Technical Field

[0001] The utility model relates to the technical field of connecting structures of agricultural machinery accessories, in particular to a connecting bracket for agricultural machinery accessories and a connecting structure for tractor accessories. Background Art

[0002] When manufacturing agricultural machinery such as tractors, it is necessary to provide installation positions for various accessories such as a mower control mechanism, a front floor connecting bracket, and an oil suction filter.

[0003] In the original tractor models, brackets are mostly made of sheet metal bending. The brackets are fixed on the chassis or other fixed entities of the tractor to provide installation points for accessories such as the front floor connecting bracket and the oil suction filter. Then, the floor is fixed on the front floor connecting bracket, and the curved beam with a ladder is fixed on the floor. At the same time, when the tractor is hooked up to a mower, the mower control mechanism is also hooked up to the bracket. Due to the large span of the sheet metal bending bracket, it not only occupies a large space, but also the sheet metal is easily deformed, resulting in unstable connection of the front floor connecting bracket; at the same time, the mower control mechanism shakes, making the operation accuracy and comfort insufficient.
