Description

Dust arrester for motor

Technical field

This utility model relates to dust removal field of dispelling the heat, a kind of dust arrester for motor.

Background technology

Using for a long time along with motor, typically there will be motor overheating phenomenon, the overheated insulation for motor is not Profit.Motor is exactly stator winding insulation to the position that exothermic reaction is most sensitive, and every kind of insulant can only bear certain temperature Degree, exceedes the temperature self allowed, and will accelerate the aging of insulation, shortens the service life of motor, but also may be because of insulation Damage and cause various accident.

Existing technique, in the cutting process of timber, can produce substantial amounts of wood flour, after these wood flours fall on motor, by Not clearing up in for a long time, causing wood flour to be deposited in the heat causing motor to produce in motor surface can not effectively shed, and heat is once Can not effectively shed, motor overheating phenomenon can be caused, thus affect the use of motor.

Utility model content

This utility model is in order to solve during timber cuts, owing to wood flour accumulation causes the phenomenon of motor overheating, The purpose of this utility model is to provide a kind of dust arrester avoiding wood flour to be deposited on motor.

This utility model provides the base case to be: for the dust arrester of motor, including motor be connected to outside motor Dedusting mechanism, wherein, on the output shaft of motor connect have plastic jacket, plastic jacket to be provided with through hole, through hole is provided with ferrum The contiguous block of matter, contiguous block is connected on output shaft, and dedusting mechanism includes shell and hairbrush, and one end of shell is provided with entrance, outward The other end of shell is provided with circular hole, and a part of surface of circular hole is provided with Magnet layer, and Magnet layer is corresponding with contiguous block, and enclosure sets Having the containing cavities for placing motor, the inwall of shell connects has pole group, pole group to include the first pole and the second pole, the One pole and the second pole are oppositely arranged, and connecting between the first pole and the second pole has annulus, annulus to match with motor, hair Brush is connected on the inwall of shell, and the other end of hairbrush offsets with motor.

The operation principle of base case: put in the containing cavities of shell after motor is passed through the entrance of shell, motor quilt Being fixed in annulus, after the output shaft of motor is positioned in circular hole, the contiguous block on output shaft is relative with circular hole, during motor running, Output shaft rotation, contiguous block is along with rotation, and owing to contiguous block is irony, when contiguous block rotates, the Magnet layer on circular hole is at ferrum Rotate along with contiguous block under the sucking action of matter, thus cover of driver rotates, the brush movement that enclosure and motor offset, from And the wood flour piled up on motor is purged, complete the dust removal operation to motor.

Base case provides the benefit that: by arranging the contiguous block of irony, utilize Magnet layer and irony contiguous block it Between sucking action so that while motor operates, dedusting mechanism carries out dust removal operation to motor, it is to avoid wood flour is at motor On accumulation, eliminate motor because wood flour pile up produce superheating phenomenon.

Preferred version one: based on scheme preferred, annulus is provided with polishing layer towards the end face of motor.Beneficial effect: By annulus is arranged polishing layer, reduce shell rotate time, the annulus abrasion to motor.

Preferred version two: preferably one preferred, the sidewall of shell has passage.Beneficial effect: by On the sidewall of shell, passage is set, distributing of the heat that beneficially motor produces.

Preferred version three: preferably two preferred, one end of hairbrush is provided with connecting rod, and connecting rod is interior with shell Wall is slidably connected.Beneficial effect: by arranging connecting rod, it is achieved that removably connecting on hairbrush wall in the enclosure, it is simple to right The cleaning of hairbrush.

Excellent alternative four: preferably three preferred, passage is provided with drainage screen.Beneficial effect: by ventilation Hole arranges drainage screen, it is therefore prevented that the wood flour of housing exterior enters enclosure.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation for the dust arrester embodiment of motor.

Detailed description of the invention

Below by detailed description of the invention, this utility model is described in further detail:

Reference in Figure of description includes: motor 100, output shaft 101, plastic jacket 103, contiguous block 105, outer Shell 107, hairbrush 109, passage 113, entrance 115, circular hole 117, Magnet layer 119, containing cavities the 123, first pole 125, second Pole 127, annulus 129, connecting rod 131.

The dust arrester for motor as shown in Figure 1, including motor 100 be connected to the dust removal machine outside motor 100 Structure, the output shaft 101 of motor 100 connects and has plastic jacket 103, plastic jacket 103 to be provided with through hole, and through hole is provided with irony Contiguous block 105, contiguous block 105 is connected on output shaft 101, and dedusting mechanism includes shell 107 and hairbrush 109, shell 107 Sidewall has passage 113, and passage 113 is provided with drainage screen, and one end of shell 107 is provided with entrance 115, another of shell 107 End is provided with circular hole 117, and a part of surface of circular hole 117 is provided with Magnet layer 119, and Magnet layer 119 is corresponding with contiguous block 105, outward Shell 107 is internal is provided with the containing cavities 123 for placing motor 100, and the inwall of shell 107 connects has pole group, pole group to include First pole 125 and the second pole 127, the first pole 125 and the second pole 127 be oppositely arranged, the first pole 125 and second Connecting between bar 127 has annulus 129, annulus 129 to match with motor 100, and annulus 129 is provided with throwing towards the end face of motor 100 Photosphere, hairbrush 109 is connected on the inwall of shell 107, and one end of hairbrush 109 is provided with connecting rod 131, connecting rod 131 and shell The inwall of 107 is slidably connected, and the other end of hairbrush 109 offsets with motor 100.

Putting into after motor 100 passes through the entrance 115 of shell 107 in the containing cavities 123 of shell 107, motor 100 is consolidated It is scheduled in annulus 129, after the output shaft 101 of motor 100 is positioned in circular hole 117, the contiguous block 105 on output shaft 101 and circular hole 117 relatively, and when motor 100 operates, output shaft 101 rotates, and contiguous block 105 is along with rotation, owing to contiguous block 105 is irony, when When contiguous block 105 rotates, the Magnet layer 119 on circular hole 117 rotates along with contiguous block 105 under the sucking action of irony, thus Cover of driver 107 rotates, and the internal hairbrush 109 offseted with motor 100 of shell 107 moves, thus to the wood piled up on motor 100 Bits are purged, and complete the dust removal operation to motor 100.By arranging the contiguous block 105 of irony, utilize Magnet layer 119 and ferrum Sucking action between the contiguous block 105 of matter so that dedusting mechanism carries out dedusting to motor 100 while motor 100 operates Operation, it is to avoid wood flour accumulation on motor 100, eliminates motor 100 because wood flour piles up the superheating phenomenon produced.Pass through Annulus 129 is arranged polishing layer, reduce shell 107 rotate time, the annulus 129 abrasion to motor 100.By at shell Distributing of passage 113, the beneficially heat of motor 100 generation is set on the sidewall of 107.By arranging connecting rod 131, it is achieved Hairbrush 109 removably connecting on shell 107 inwall, it is simple to the cleaning to hairbrush 109.By passage 113 is arranged Drainage screen, it is therefore prevented that it is internal that the wood flour outside shell 107 enters shell 107.
