Rotary shot blasting machine for concrete mixing drum

Abstract

The invention discloses a rotary shot blasting machine for a concrete mixing drum. The rotary shot blasting machine is good in cleaning effect. The rotary shot blasting machine comprises a machine frame. The machine frame is supported on the ground. A conveying trolley is arranged on one side of the machine frame. Sliding wheels are arranged at the lower end of the conveying trolley. The two ends of the concrete mixing drum are rotationally arranged on a supporting roller. High-frequency adjustable-speed motor driving devices are arranged on the conveying trolley and located on the two sides of the supporting roller respectively. Motor shafts of the high-frequency adjustable-speed motor driving devices are provided with riding wheels matched with the concrete mixing drum. A plurality of shot blasting devices are evenly arranged inside the upper end of a cleaning room. Triangular vertical air outlet channels are arranged on the two edges of one side in the cleaning room. A triangular transverse air outlet channel is connected with a lifting machine arranged outside one side of the cleaning room.

Description

technical field [0001] The invention relates to a shot blasting machine, in particular to a concrete mixing drum rotary shot blasting cleaning machine. Background technique [0002] The surface of the concrete mixing drum needs to be treated with a shot blasting machine in the process of processing to make the surface smooth and show the natural color of the metal, eliminate the internal stress of the workpiece, improve the fatigue resistance of the workpiece, increase the adhesion of the paint film when the workpiece is painted, and Finally, the surface and internal quality of the workpiece can be improved. In the process of cleaning the concrete mixing drum, the existing shot blasting cleaning machine tends to leave a dead angle at the contact part between the concrete mixing drum and the conveying trolley, resulting in substandard quality. At the same time, the existing structure of the air outlet of the shot blasting machine must communicate with the main cleaning r...

Problems solved by technology

In the process of cleaning the concrete mixing drum, the existing shot blasting machine tends to leave dead angles at the contact part between the concrete mixing drum and the conveying trolley, resulting in substandard quality

At the same time, the existing structure of the air outlet of the shot blasting machine must communicate with the main cleaning room due to the fluid power during the dust discharge of the shot blasting room. The blow of the steel shot, the air outlet is limited by the material selection and the welding structure is easy to be damaged, which requires frequent maintenance and affects the production efficiency

In addition, the diversion and guidance of the dust is also unstable, which is prone to turbulence, and the dust is not easy to be sucked into the dust exhaust duct, resulting in more dust in the shot blasting parts, which cannot achieve the ideal effect of cleaning or strengthening the surface
