Description

Technical Field

[0001] The utility model relates to the technical field of guardrail processing, in particular to a steel guardrail shot blasting machine. Background Art

[0002] Shot blasting machine is a mechanical equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of the workpiece. The shot blasting machine can simultaneously remove sand, core and clean the castings. It can also be used for surface treatment of forgings, aluminum-magnesium alloy parts, sheet metal welded parts, etc. During the processing of steel guardrails, shot blasting machines are required for processing.

[0003] The publication number in the existing public technology is: CN218697747U. A steel guardrail shot blasting machine comprises a processing box and also comprises: a bearing column fixedly arranged in the processing box; a shot blasting mechanism comprises a movable block slidably sleeved on the bearing column, a mounting rod is arranged above the movable block, and an adjusting component is arranged between the mounting rod and the movable block. A fixed arm is arranged on one side of the mounting rod, and mounting plates are fixedly connected to both sides of the fixed arm, and one of the mounting plates is rotatably connected to the mounting rod. An adjusting rod is threadedly penetrated on the mounting plate on one side of the mounting rod, and a clamping rod is rotatably connected on one side of the adjusting rod. A rotating column is rotatably penetrated on the mounting plate on the side of the fixed arm away from the mounting rod, and the clamping rod is fixedly connected at one end of the rotating column. A face-changing component is arranged on the outer wall of the mounting plate away from the clamping rod, and the side wall of the processing box is slidably connected to the movable rod, and an electric telescopic column is fixedly connected between the movable rod and the top wall of the processing box, and the bottom of the movable rod is fixedly connected to the shot blasting machine.

[0004] However, the above patent still has certain disadvantages when in use: during operation, since the structures of the shot blasting machine and the fixed guardrail are fixed at specific positions, this leads to certain limitations on the position where the shot blasting machine can act on the guardrail, resulting in limited orientation of the guardrail that can be processed. Some parts and corners that exceed the operating range of the shot blasting machine cannot be effectively processed, and the overall operating range is small, which in turn affects the overall processing effect, resulting in less than ideal use of the device.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
