Embodiment 1

[0024] Reference Figure 1-5 , An electrostatic dust removal cover for drilling holes for construction, including a fixed sleeve 1 installed on the drilling rig 7 and the drill bit 71, a hollow sleeve 2 is installed on the fixed sleeve 1, and the end of the hollow sleeve 2 is installed away from the fixed sleeve 1 There is a dust cover 3, a plurality of metal dust removal nets 31 are installed radially in the dust cover 3, and a brush ring 4 and a reversing ring 5 are installed at the bottom of the dust cover 3. The diameter of the brush ring 4 is larger than the diameter of the reversing ring 5. A protective cover 6 is rotatably installed on the outer side wall of the brush ring 4, and a plurality of insulating fixing rods 61 and a plurality of metal fixing rods 62 are installed annularly and equidistantly on the side of the protective cover 6 close to the hollow sleeve 2, each insulating fixing rod 61 A first brush 611 is installed on each of them, and a plurality of first bru...

Embodiment 2

[0032] Reference Figure 6-7 , A drilling electrostatic dust removal cover for construction, which is basically the same as the first embodiment, the difference lies in:

[0033] The plurality of second brushes 621 are all located between the reversing ring 5 and the drill bit 71 and the plurality of second brushes 621 are only in contact with the reversing ring 5, one end of the metal fixing rod 62 passes through the protective cover 6 and extends To the dust hood 3.

[0034] In this embodiment, the second brush 621 is negatively charged so that the metal fixed rod 62 is negatively ionized. Since the metal fixed rod 62 is not in contact with the material, it is suitable for drilling and dust removal of all materials.

Abstract

The invention discloses a drilling electrostatic dust collection cover for building construction. The dust collection device comprises a fixing sleeve installed on a drilling machine and a drill bit in a sleeving mode, a hollow sleeve is installed on the fixing sleeve, a dust removal cover is installed at the end, away from the fixing sleeve, of the hollow sleeve, a plurality of metal dust removalnets are installed in the dust removal cover in the radial direction, and an electric brush ring and a reversing ring are installed at the bottom of the dust removal cover. Partial rotation amount ofthe drill bit is converted into electric energy through the magnetic strips and the coil windings, and through the reversing ring, the first electric brush and the second electric brush, the metal dust removal net is positively charged to adsorb dust which is negatively charged and ionized by the drill bit or the metal fixing rod, so that energy waste is avoided, dust can be removed under the condition of not contacting with materials, and the dust collection cover has environmental protection property, reliability and wider applicability.

Description

Technical field [0001] The invention relates to the field of building construction, in particular to a drilling electrostatic dust removal cover for building construction. Background technique [0002] In the process of building construction, electric drills are often used to drill and install buildings or building materials. Electric drills are prone to generate a lot of dust during the drilling process, and most of the electric drills are close to the head, which may cause dust to be trapped in the nasal cavity. Inhalation is hazardous to health. [0003] Existing construction drilling generally uses water sprinkling to remove dust, but a large number of drilling parts need to waste a lot of water to remove dust, and some construction material drilling cannot be used to remove dust, which may cause material damage. Summary of the invention [0004] The purpose of the present invention is to solve the disadvantages of large waste of water spraying and dust removal in the prior art...
