Hydraulic feeding and fragmentation mine car of stone sawing machine

Abstract

The invention provides a hydraulic feeding and fragmentation mine car of a stone sawing machine. The hydraulic feeding and fragmentation mine car is high in use safety performance and capable of greatly improving stone cutting work efficiency. The hydraulic feeding and fragmentation mine car comprises two transverse guide rails, a lower car body, an upper car body, four plate push oil cylinders, four coamings and four swing arms, the lower car body is arranged on the two transverse guide rails in a transverse sliding mode, the upper car body is arranged on a longitudinal guide rail of the lower car body in a longitudinal sliding mode, a front transmission support is arranged at one end of the lower car body, an oil cylinder is further arranged between the lower car body and the upper car body, a cylinder body of the oil cylinder is fixedly connected with a transmission support, a rear transmission support is arranged at the position, corresponding to the transmission support, of the end, away from the transmission support, of the upper car body, a piston rod of the oil cylinder is connected with the rear transmission support of the upper car body, the coamings can be opened and closed and are arranged on the side edge around the lower car body, the height of each coaming is larger than that of the upper car body, hinge seats are respectively arranged on the peripheral side of the lower car body, hinge buckles are arranged on the lower portions of the coamings respectively, and the hinge buckles and the corresponding hinge seats are rotatably hinged together through pin shafts respectively.

Description

technical field [0001] The invention relates to a mine car with a knife, in particular to a mine car with a hydraulic knife for a stone saw machine. Background technique [0002] At present, after a stone saw machine cuts one knife, the block must be moved relative to the main machine when the next knife is cut, that is, the knife is cut into pieces. The traditional knife-feeding piece mining car has a complex structure and requires manual labor when feeding the knife. Auxiliary completion, labor-intensive, time-consuming, low production efficiency, inconvenient operation, can not guarantee safe operation, and the positioning effect is not good after the knife is fed, resulting in the swing of the block during the cutting process, increasing energy consumption, and noise during operation Big. In addition, the cutting-feeding and slicing mine car that is matched with the existing stone sawing machine is equipped with a protective fence at the end of four rotations. When work...

[0002] At present, after a stone saw machine cuts a knife, the block must be moved relative to the main machine when the next knife is cut, that is, the knife is cut into pieces. The traditional knife-feeding piece mining car has a complex structure and requires manual labor when feeding the knife. Auxiliary completion, labor-intensive, time-consuming, low production efficiency, inconvenient operation, can not guarantee safe operation, and the positioning effect is not good after the knife is fed, resulting in the swing of the block during the cutting process, increasing energy consumption, and noise during operation Big

In addition, the cutting-feeding and slicing mine car that is matched with the existing stone sawing machine is equipped with a protective fence at the end of four rotations. When working, the slicing is in a high-speed rotating state, thus generating a strong centrifugal force, and the sewage that is brought out splashes everywhere. Due to the quality factor of the welding between the substrate and the alloy cutting head, or the material factor of the stone body, sometimes the alloy cutting head will fly off the slicing substrate and cause industrial accidents. Nowadays, the factory area is surrounded by wooden boards or waste boards, which not only affects the factory view but also easily damaged, and it is easy to fall due to irregular placement, burying a safety hazard
