Description
Technical field
Drill bit device is heated the present invention relates to the microwave in industry drilling, cutting, crushing technology field, it is characterized in that utilizing
The equipment that microwave is drilled to non-conductive material, is mainly used in building, finishing, material cutting, catalase and ore deposit
The industry field that mountain drilling well etc. is handled hard non-conductive materials.
Background technology
At present, drill, cut, crushing technology field mainly use mechanical device, mainly by improve the kinetic energy of drill bit come
Realize, therefore also tend to noise, vibration, dust etc. with product, efficiency is low, to builder, drilling engineer, geology
Investigation and prospecting person's human body has certain harm.At present, microwave heating bit technique product is yet there are no both at home and abroad to lead in construction and decoration
The document report of domain field application.
The content of the invention
To overcome conventional drill topping machanism to have the deficiencies such as noise, vibration, dust, the purpose of the present utility model is
In order to send out out a kind of quieter, gentle, easily drill bit so that can reduce noise during the operation such as drilling, cutting, broken, shake
The adjoint product such as dynamic and dust, more efficiently.
In order to solve the above technical problems, the present invention uses following series technical project:
A kind of drill bit with following structure is provided:It include microwave generator, microwave adapter, rectangular waveguide, rectangle-
Coaxial waveguide converter, coaxial waveguide, near-field energy aggregator and control circuit.It is characterized in that microwave generator passes through microwave
Adapter is connected with rectangular waveguide, rectangle-coaxial waveguide converter connection rectangular waveguide and coaxial waveguide, near-field energy aggregator
Positioned at coaxial waveguide end, contacted with pending non-conductive material.
Microwave generator is powered by the electric power system of power adjustable.
Coaxial waveguide is made up of external conductive shell, insulating sleeve.
Near-field energy aggregator is made up of external conductive shell, insulating sleeve, tuned reflective mirror, insulating supporting and electrode needle,
Electrode needle is located at coaxial waveguide inside center, coaxial with coaxial waveguide.
Electrode needle is connected with rotary drive mechanism, and the rotary drive mechanism includes single motor or motor and speed changer knot
The drive mechanism of conjunction.
Electrode needle also functions to the effect of drill bit in itself, in microwave bores processing materials process, can occur soon in material surface
The thermal runaway phenomenon of speed, produces a hot localised points, and drill bit will be crept into along the direction of focus.
Electrode needle lateral dimension is less than the wavelength of microwave.
The drill bit heated based on microwave belongs to a kind of heat energy drilling equipment, and innovation of the invention is microwave energy
By near-field energy aggregator, the region concentrated on around electrode needle, using thermal runaway effect, reaches and non-conductive material is entered
The operation such as row drilling or cutting.
The novel part of the present invention, exactly make use of the microwave near-field energy being seldom related in usually research and engineer applied
Amount and thermal runaway effect.It can be solved by Maxwell's electromagnetic equation group, near field region, electric field intensity E, magnetic vector H phases
Difference is 90 degree.From poynting's theorem, instantaneous Poynting vector is imaginary number, and energy is not radiated, therefore can be near field region
Energy is stored, electromagnetic field intensity is big.The signified situation of thermal runaway effect is that the change triggered when temperature increases makes temperature more enter
One step increases, and the object of high temperature is to microwave more preferable assimilation effect again, that is to say, that when some local temperature of material surface
After rise, under the irradiation of microwave, this portion of material can absorb most of microwave energy, cause temperature further to improve, and produce
Vicious circle, thus cause a certain destructive result.This is a kind of positive feedback.
The beneficial effects of the utility model are, using microwave near-field energy and thermal runaway effect, can be prepared into relative
Simple and portable drilling tool, as a kind of contactless physics auxiliary rock method, will not bring new rush to drill bit
The collateral damage such as hit, wear and tear, noise and dust will not be produced, it is not necessary to the drill bit of rotation, and work materials are entered at a high speed
Row handle in advance, reduce drill bit work difficulty, effectively reduction drilling process in drill string vibration and efficiency can be improved.Cause
This greatly reduces limitation of the construction and decoration industry to the engineering time and the injury to workmen.
