Technical Field

The invention relates to the field of building construction, in particular to a drilling electrostatic dust hood for building construction.

Background

In the building construction process, often can use the electric drill to carry out the installation of driling to building body or building material, the electric drill easily produces a large amount of dusts in drilling process, and most electric drill construction is nearer apart from the head, consequently easily leads to the dust to be inhaled by the nasal cavity and endangers healthily.

The existing construction drilling holes generally adopt watering for dust removal, but a large amount of water resources are wasted when a large amount of drilling parts are watered for dust removal, and partial building material drilling holes cannot be watered for dust removal, so that the material damage is easily caused.

Disclosure of Invention

The invention aims to solve the defects that the water sprinkling and dust removing waste is large and part of materials are not suitable for water sprinkling and dust removing in the prior art, and provides a drilling electrostatic dust removing cover for building construction.

In order to achieve the purpose, the invention adopts the following technical scheme:

a drilling electrostatic dust removal cover for building construction comprises a fixed sleeve which is sleeved on a drilling machine and a drill bit, wherein a hollow sleeve is installed on the fixed sleeve, one end, far away from the fixed sleeve, of the hollow sleeve is provided with a dust removal cover, a plurality of metal dust removal nets are radially installed in the dust removal cover, an electric brush ring and a reversing ring are installed at the bottom of the dust removal cover, the diameter of the electric brush ring is larger than that of the reversing ring, the outer side wall of the electric brush ring is rotatably provided with a protective cover, a plurality of insulating fixing rods and a plurality of metal fixing rods are installed on one side, close to the hollow sleeve, of the protective cover in an annular equidistant mode, each insulating fixing rod is provided with a first electric brush, the first electric brushes are all located between the electric brush ring and the reversing ring and are in mutual contact, each metal fixing rod is provided with a second electric brush, and the inner wall, the outer side wall of the synchronous rotating sleeve is embedded with a plurality of magnetic stripes, the hollow inner wall of the hollow sleeve is provided with a plurality of coil windings, the coil windings are electrically connected with the reversing ring, and the electric brush ring is electrically connected with the metal dust removal net.

Preferably, a plurality of said second brushes are each located between the commutating ring and the drill bit and are in contact with each other.

Preferably, the first brushes correspond to the magnetic strips of the N poles one by one, and the second brushes correspond to the magnetic strips of the S poles one by one.

Preferably, a plurality of the second brushes are all located between the reversing ring and the drill bit and only contact with the reversing ring, and one end of the metal fixing rod penetrates through the protective cover and extends into the dust removal cover.

The invention has the following beneficial effects:

1. the drill bit rotates to drive the synchronous rotating sleeve to rotate, so that the magnetic strip on the synchronous rotating sleeve can move relative to the coil winding, induced current is generated in the coil winding and is conducted to the first electric brush and the second electric brush through the reversing ring, the first electric brush is conducted to the metal dust removal net through the electric brush ring to enable the metal dust removal net to be positively charged, the second electric brush is conducted to the drill bit or the metal fixing rod 62 to enable the metal dust removal net to be negatively charged, the drill bit or the metal fixing rod with the negative charge is ionized to enable dust to be negatively charged, the dust with the negative charge is adsorbed to the metal dust removal net with the positive charge to achieve the purpose of dust removal, energy waste is avoided, the drill bit ionization is suitable for insulating material drilling and dust removal, and.

2. The magnetic stripe one-to-one of a plurality of first brushes and a plurality of N utmost points, the magnetic stripe one-to-one of a plurality of second brushes and a plurality of S utmost points, then first brush and second brush make positive electricity all the time on the first brush when rotating the contact on the switching-over ring, all the time the negative electricity on the second brush, then the metal that can harm removes dust and adsorbs the dust all the time positively charged on the net, and the negative electricity ionization all the time on drill bit or the metal dead lever for the equipment removes dust more reliably.

In conclusion, the invention converts partial rotation quantity of the drill bit into electric energy through the magnetic strip and the coil winding, and enables the metal dust removing net to be positively charged to adsorb dust which is negatively charged and ionized by the drill bit or the metal fixing rod through the reversing ring, the first electric brush and the second electric brush, thereby avoiding energy waste, and removing the dust without contacting materials, so that the dust removing net has environmental protection, reliability and wider applicability.
