Description

Technical Field

[0001] This invention belongs to the technical field of tracked shot blasting machines, and in particular relates to a flexible loading and unloading device for tracked shot blasting machines. Background Technology

[0002] For tracked shot blasting machines, a hollowed-out track mechanism is set in the upper part of the machine housing, the shot blasting system is installed directly above the track mechanism, a shot recovery mechanism is set below the track mechanism, and a concave working area is set above the track mechanism. The track mechanism is used for continuous flipping of the workpiece to ensure uniform shot blasting.

[0003] As for loading and unloading the shot blasting machine, the workpiece is thrown directly onto the track by manual labor or by a hydraulic tilting device. The workpiece will directly hit the track. Since the ground has no support in the concave working area of ​​the track, the pressure is mainly borne by the track itself and the rollers on the track, which will damage the track. Over time, it will affect the normal use of the track.

[0004] Therefore, designing a flexible loading and unloading device is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a flexible loading and unloading device for a tracked shot blasting machine. By designing a flip-up conveyor belt mechanism, and with the rotation point of the conveyor belt mechanism concentric with the front roller of the shot blasting machine's track mechanism, the distance between the conveyor belt mechanism and the front roller remains constant during rotation. At the same time, the side support frame can be used to lift and support the conveyor belt mechanism through pushing and supporting. Through the transmission of the conveyor belt mechanism and the cooperation of the shot blasting machine's track mechanism, flexible loading and unloading can be performed, avoiding impact and damage to the shot blasting machine's track, and ensuring the track's positional stability and service life.
