The invention relates to the technical field of machinery, and provides a protective device, a steering system and an operation machine.The protective device is used for protecting a steering connecting rod and a steering support and comprises a protective cover and a waterproof structure, and the protective cover is in a hollow pipe shape and sleeves the periphery of the steering connecting rod; the top end of the protective cover is tightly attached to the steering connecting rod, and the bottom end is arranged on a vehicle body bottom plate. The waterproof structure is arranged on the top of the vehicle body bottom plate and located on the peripheral side of the through hole. According to the protection device, the protection cover is used for achieving primary protection on the steering connecting rod, and most dust can be prevented from entering the steering connecting rod in the working process; by arranging the waterproof structure, when a driver flushes the cab through a high-pressure water pipe and part of sewage permeates into the inner side of the protective cover, the waterproof structure can prevent the sewage from staying on the periphery of the waterproof structure and preventing the sewage from entering the through hole; secondary protection on the steering bracket is realized; and the dustproof and waterproof effects are achieved, the structure is simple, and the good protection effect is achieved.

    本发明涉及机械技术领域,提供一种防护装置、转向系统及作业机械,其中防护装置用于防护转向连杆和转向支架,包括防护罩和防水结构,防护罩为中空管状,且套设于转向连杆的外周;防护罩的顶端与转向连杆紧密贴合,底端设置于车身底板上;防水结构设置于车身底板的顶部,且位于贯穿孔的外周侧。本发明提供的防护装置,通过防护罩用于实现对转向连杆的一级防护,可以防止工作过程中的大部分灰尘进入转向连杆;通过设置防水结构,当驾驶员用高压水管冲洗驾驶室时,部分污水渗入到防护罩内侧时,防水结构可阻挡污水停留在防水结构的外周,防止污水进入贯穿孔处;实现对转向支架的二级防护;不仅可以防尘还可以防水,结构简单且具有良好的防护效果。
