Drilling machine with dust-collecting device

Abstract

The invention discloses a drilling machine with a dust-collecting device. The drilling machine comprises a drill rod, a power mechanism and the dust-collecting device, wherein the power mechanism is used for driving the drill rod to rotate; the duct-collecting device consists of a flow guide barrel and a dust-collecting barrel; a baffle plate for blocking dust-containing air flow is arranged at one end of the flow guide barrel; an installing hole is formed in the baffle plate; the baffle plate of the flow guide barrel is connected integrally with the power mechanism through a connection flange; the drill rod which is connected with the power mechanism penetrates through the installing hole in the baffle plate and extends out after passing through the inner cavity of the flow guide barrel; the duct-collecting barrel is positioned below the flow guide barrel; one end of the dust-collecting barrel is fixedly connected with the flow guide barrel integrally to ensure the communication of the inner cavities of the dust-collecting barrel and the flow guide barrel; the outer wall of the dust-collecting barrel is provided with a conveying pipeline which is connected with an external water supply device; the inner barrel wall of the dust-collecting barrel is provided with a plurality of nozzles which are communicated with the conveying pipeline. By adopting the drilling machine, the dust-containing air flow can be collected in the working process of the drilling machine, so that dust is prevented from being dispersed in a working environment and causing discomfort of the lungs of operators; moreover, the structure is simple, and the dust collecting efficiency is high.

Description

technical field [0001] The invention relates to a drilling machine, in particular to a drilling machine with a dust collecting device. Background technique [0002] As we all know, whether it is a coal mine drilling rig or other rock drilling rigs, a lot of dust is usually generated due to vibration during its work. These dusts permeate the working environment. After the operator inhales the lungs, it will cause lung discomfort Then cough, throat discomfort, serious cause lung disease, will cause great harm to the body of the operator, seriously affect the health and work efficiency of workers, and also cause certain pollution to the surrounding environment, according to the investigation , Dust is one of the causes of smog in today's society; [0003] At present, the drilling rigs with dust removal devices are studied at home and abroad, but the drilling rigs that can really be used for production work are very rare. Even the existing drilling rigs with dust removal device...

[0002] As we all know, whether it is a coal mine drilling rig or other rock drilling rigs, a lot of dust is usually generated due to vibration during its work. These dusts permeate the working environment. After the operator inhales the lungs, it will cause lung discomfort Then cough, throat discomfort, serious cause lung disease, will cause great harm to the body of the operator, seriously affect the health and work efficiency of workers, and also cause certain pollution to the surrounding environment, according to the investigation , Dust is one of the causes of smog in today's society;

[0003] At present, the drilling rigs with dust removal devices are studied at home and abroad, but the drilling rigs that can really be used for production work are very rare. Even the existing drilling rigs with dust removal devices that can be produced and put into use are very expensive. Moreover, the dust removal efficiency is not high, and it is difficult to achieve real popularization in application.
