Abstract
The utility model relates to a negative-pressure dust-removing rotating device, which consists of an umbrella cylinder, a rotating upper cylinder, a base, a rotating connecting cylinder, a bracket, a handle, a thrust bearing, a dust removing cover and a rotating shaft. The umbrella cylinder is arranged at the front end of the rotating upper cylinder; the rotating upper cylinder is arranged on the base; the base is provided with the thrust bearing; and the rotating connecting cylinder is arranged on the shaft of the thrust bearing and is connected with the rotating upper cylinder. The utility model has the advantages of simple structure and reasonable design. Moreover, the utility model not only can rotate leftwards and rightwards on a horizontal plane, but also can rotate upwards and downwards in the vertical direction, thereby completely dedusting the tunneling machine and satisfying the needs of the tunneling machine for the dust removal.
Description
Technical field: the utility model relates to a kind of development machine depression dust-removing slewing equipment, for development machine up and down and a kind of dust arrester that can together move with cutting units rapidly is provided during horizontal cut.
Background technology: at present, development machine depression dust-removing slewing equipment structure design is unreasonable, slewing equipment can only be on horizontal plane left-right rotation, can not rotate down in vertical direction, the dust pelletizing system of development machine is restricted in design, influences dust removing effects, do not reach the dedusting requirement of development machine in the excavation operation in tunnel or tunnel, influence the healthy of operating personnel, influence the normal operation of development machine.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of development machine depression dust-removing slewing equipment is provided, it mainly solved existing development machine depression dust-removing slewing equipment can only be on horizontal plane left-right rotation, can not rotate down in vertical direction, the dust pelletizing system of development machine is restricted, and influences problems such as dust removing effects.The purpose of this utility model is achieved in that development machine depression dust-removing slewing equipment is made of: umbrella shape tube, revolution top cylinder, base, revolution extend neck, support, handle, thrust bearing, clear dirt lid, rotating shaft.The umbrella shape tube is the umbrella shape globoidal structure, it is installed in the front end of revolution top cylinder by rotating shaft, the revolution top cylinder is installed on the base by screw, thrust bearing is housed on the base, the revolution extend neck is installed on the axle of thrust bearing, it is connected with the revolution top cylinder, and the revolution extend neck is provided with clearly the dirt lid and is equipped with handle and support.This product structure is simple, and is reasonable in design, slewing equipment can not only be on horizontal plane left-right rotation, can also rotate down in vertical direction, can realize the comprehensive dedusting of development machine, can satisfy development machine dedusting requirements of one's work.
