Description

Technical Field

[0001] The utility model belongs to the technical field of bulk material loading and unloading, and relates to a semi-gantry double-screw reclaimer. Background Art

[0002] Semi-gantry reclaimer is a common material reclaiming system, widely used in steel, cement, chemical and other industries. It is used for material reclaiming operations in long material yards and can be arranged and used indoors or outdoors.

[0003] The existing semi-gantry reclaimer is generally a semi-gantry scraper reclaimer. The reclaiming mechanism of the semi-gantry scraper reclaimer is mainly composed of a scraper, a chain sprocket and a drive. When the equipment is running, the scraper is driven to reciprocate by the chain to scrape the material out of the silo. Since the reclaiming arm of the existing semi-gantry scraper reclaimer adopts a scraper chain method, the structure is relatively complex. In order to prevent faults including chain jumping, chain breaking and chain dropping, timely maintenance and maintenance are required, which puts forward higher requirements for the inspection and maintenance of the equipment. At the same time, since the chain and sprocket will make a relatively loud noise during operation, if there is no good noise reduction measure, it will cause great inconvenience to the staff.

[0015] The following describes the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. The following embodiments and the features in the embodiments can be combined with each other without conflict.

[0016] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on the present utility model. In order to better illustrate the embodiments of the present utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0017] The same or similar numbers in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "upper", "lower", "left", "right", "front", "back" and the like indicate directions or positional relationships, they are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
