The specific embodiment
Below be further elaborated based on the specific embodiment of accompanying drawing to the utility model.Should be appreciated that specific embodiment described herein only as embodiment, and be not used in the protection domain that limits the utility model.
See also Fig. 3 to Fig. 6, be a kind of nozzle 10 that is used for dust-blowing device that present embodiment provided.Said nozzle 10 comprises one first nozzle 11; Second nozzle 12 that is arranged on said first nozzle 11; An and clamping shell fragment 13 that is arranged in said second nozzle 12, and water conservancy diversion loudspeaker 14 that are arranged on said second nozzle 12 and are positioned at first nozzle, 11 opposite sides.In the present embodiment, said first nozzle 11 is connected with snap fit with second nozzle 12.Said clamping shell fragment 13 is used for fixing the relative position of said first, second nozzle 11,12 between axially.
Said first nozzle 11 comprises one first body 111; First siphon port 112 that is arranged on this first body 111; 113, one of an internal thread hole of jet end that are used to connect air drifting dust rifle (figure do not show) that are arranged on these first body, 111 1 ends is arranged on first clip-connecting rod 114 that is used to connect second nozzle 12 of the other end of said this first body 111.Said first siphon port 112 is opened on the sidewall of said first body 111, is evenly distributed with four first siphon port 112 in the present embodiment.What can expect is that a plurality of these first siphon port 112 arbitrarily can be set as required.The shape of this first siphon port 112 can be made as triangle, oval hole shape, circle, square or other various geometries on demand, and size also is able to suitably change, and looks demand fully and changes.When said first nozzle, 11 jet flows go out swiftly flowing compressed air; Air storage capacity with the flow consumed cabin air compressor of 150 liters of per minutes; When these first nozzle, 11 jet flows go out the air of low-voltage high speed; First siphon port 112 around this first nozzle 11 forms vacuum states, sinks the air of first siphon port, 112 external high pressures, and a large amount of air flow into compressed air with high speed jet in first nozzle, 11 internal mix jet flows by first siphon port 112; Thereby increase the flow of air-flow, and then increase dust removing effects.Said first clip-connecting rod 114 is provided with at least one clamping hole 115, is used for matching with said clamping shell fragment 13, with said first, second nozzle 11,12 of clamping.This clamping hole 115 be a kind of around the square groove of tool wall, with axially or radially mobile of restriction clamping shell fragment 13.
Said second nozzle 12 comprises that 121, one of one second bodies are arranged on second joint end 122 of these second body, 121 1 sides, and at least one is arranged on second siphon port 123 between said second body 121 and second joint end 122.In order to enlarge the dedusting area of this nozzle 10, the diameter of said second body 121 is greater than the diameter of said second joint end 122, thereby makes second siphon port 123 be arranged on the inclined-plane.In order to make each first siphon port 112 corresponding with second siphon port 123, the quantity of this second siphon port 123 equates with the quantity of first siphon port 112.With first siphon port 112, said second siphon port 123 has identical effect with first siphon port 112.The madial wall of said second joint end 122 is provided with a shell fragment holddown groove 124, is used for ccontaining said clamping shell fragment 13, its length greater than with the length of this clamping shell fragment 13 when not compressing.Said second body 121 is provided with external screw thread with respect to an end of the end 122 that is spirally connected, to be spirally connected with water conservancy diversion loudspeaker 14.
Said clamping shell fragment 13 comprises 131, one Access Divisions 132 that are connected with this stiff end 131 of a stiff end, and an elongated end 133.Said stiff end 131 is fixed on the side towards inlet of said shell fragment holddown groove 124, is beneficial to when first clip-connecting rod 114 during from this inlet insertion second joint end 122, and said clamping shell fragment 13 is fixed, and moves to elongated end 133.Said stiff end 131 and elongated end 133 all can be arc, so that it has elasticity.Said Access Division 132 cooperates with clamping hole 115 to be replaced, and is limited in wherein by clamping hole 115, so these Access Division 152 best axis perpendicular to said first clip-connecting rod 114.Said elongated end 133 abuts against in the shell fragment holddown groove 124, when first clip-connecting rod 114 when this inlet inserts second joint end 122, just, move to guide said Access Division 132 along the basal sliding of shell fragment holddown groove 124.
Said water conservancy diversion loudspeaker 14 can be one-body molded with second nozzle 12, also can connect through the mode of being spirally connected, and what certainly expect is that these water conservancy diversion loudspeaker 14 can also otherwise connect, like resilient key connection etc.In the present embodiment, said water conservancy diversion loudspeaker 14 are connected with the mode of being spirally connected with second nozzle 12.These water conservancy diversion loudspeaker 14 comprise 141, one of links that is used for being spirally connected with second nozzle 12 and these link 141 integrated horn mouths 142.This horn mouth 142 is gradually wide along airflow direction.Because it is far away more that high pressure draught leaves the gas outlet of air drifting dust rifle (figure does not show); Its velocity attenuation big more; It receives the influence of extraneous low-pressure air current also big more, so this moment, the opening angle of horn mouth 142 should be more little; To stop the influence of extraneous low-pressure air current, simultaneously with the high pressure draught guiding working face to external diffusion of the gas outlet of second nozzle 12.Therefore, the opening angle of this horn mouth 142 and this horn mouth 142 to first nozzles 12 are inversely proportional to the distance of the junction of air drifting dust rifle.Said water conservancy diversion loudspeaker 14 have two effects; The one, can prevent that extraneous low-pressure air current is to the interference at the high pressure draught of the gas outlet of second nozzle 12; The 2nd, can be with the high pressure draught guiding working face of the gas outlet of second nozzle 12; Thereby can reduce the influence of extraneous air-flow, to improve compressed-air actuated utilization rate.
Owing to have the clamping hole 115 of said first nozzle 11; And be arranged on the clamping shell fragment 13 on second nozzle 12; When assembling; As long as first clip-connecting rod 114 of first nozzle 11 is inserted second joint end 122 of second nozzle 12, the Access Division 132 of said clamping shell fragment 13 just can be fastened in the said clamping hole 115, and clamping shell fragment 13 moving axially or radially can be limited in clamping hole 115.Thereby can fix the relative position of said first, second nozzle.Compared with prior art, need not rotate first or second nozzle with this first, second nozzle that is spirally connected, thereby practice thrift built-up time, reduce cost of labor.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Interior any modification of doing of all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included in the utility model protection domain in.
