Description

Technical Field

[0001] The utility model relates to the technical field of bulk loaders, in particular to a bulk loader device for unloading. Background Art

[0002] In the prior art, for example, CN204021974U discloses a bulk loader for bulk cement packaging, comprising a frame, a bulk head and a lifting mechanism provided below the frame, the bulk head comprising a telescopic hose and a discharge head connected below the telescopic hose; the bulk head comprising a telescopic inner cylinder and a telescopic outer cylinder sleeved on the outer periphery of the telescopic inner cylinder; a chute is fixedly connected below the frame, a slider capable of sliding in the chute is connected to the outer periphery of the telescopic outer cylinder, an oil rope is connected to the upper end of the slider, and the other end of the oil rope passes through the chute roller and pulley in turn and is connected to the output shaft of the reducer, thereby improving the problems of the existing bulk loader having a complex structure and inaccurate positioning of the bulk head;

[0003] However, the movement of the slider in the chute is easily obstructed, resulting in uneven lifting of the bulk loader. Its telescopic range is limited by the length of the chute. In addition, the surface of the oil rope easily absorbs dust and impurities, and will become loose after long-term use and unable to bear the load, resulting in the bulk loader being unable to lift normally.

[0004] CN209601690U discloses a telescopic unloading device for a dry ash bulk loader, comprising an outer cylinder of a dry ash bulk head, an inner cylinder of the dry ash bulk head, and an ash outlet of the bulk loader; a steel inner sleeve is fixedly connected to the bottom end of the ash outlet of the bulk loader, and the lower end of the steel inner sleeve is inserted into the inner cylinder of the dry ash bulk head; an outer bag is connected to the outer wall of the dry ash bulk head and the ash outlet of the bulk loader via a clamp; the outer bag is arranged on the outside of the sealing bag and is connected to the bag dust collector via an exhaust pipe, which not only improves the airtightness of the device but also reduces the occurrence of dust problems;

[0005] However, expanding the telescopic range by using the outer and inner tubes of the bulk head cannot effectively buffer the moment the material is unloaded, and the bulk head is prone to getting stuck, resulting in the bulk head being unable to lift normally. In addition, the efficiency of controlling the telescopic range by generating an air pressure difference through vacuuming is not high enough, and the load capacity is poor. Utility Model Content

[0012] Preferably, the two guide wheel lines are respectively mounted on the two guide wheels, the lower end of the guide wheel line is movably connected to the discharge port, and the other end of the guide wheel line passes through the tensioning wheel and is connected to the reducer.
