Description
Technical field
The present invention relates to an excavator and, more particularly, in particular to a dust Duo with an automatic spray device excavators.
Background technology
All kinds of large, medium and small excavators are widely used in numerous industries such as mining industry, building, removal, water conservancy, earth and rock works; Because the frequent use of this plant equipment; The dust that causes in the operation place, severe contamination environment, very big to industrial and agricultural production and people's healthy influence; Therefore, the equipment spray dust-arrest device has become a kind of indispensable important equipment on excavator.Therefore, adopt water smoke dust-arrest device of the present invention to be equipped on the excavator, when making excavator operation, the scope of operation is closely carried out spray dust-arrest, dedusting, have advantages of high practicability and science, higher economic value and effect are arranged.
Summary of the invention
The objective of the invention is to deficiency, a kind of simple in structure, easy for installation, workable excavator that has the automatic water spray dust-arrest device is provided to above-mentioned prior art.
Technical scheme of the present invention is achieved in that a kind of excavator that has the automatic water spray dust-arrest device, comprises body, is provided with digging arm at front part of a body; Free end at digging arm is provided with Excavating bucket; On body, be provided with pressure distributor, pressure distributor is connected with hydraulic cylinder pipeline on the digging arm, and wherein said pressure distributor also pipeline is connected with hydraulic motor; The power output shaft of hydraulic motor is connected with the high pressure liquid pump; The water inlet pipeline of high pressure liquid pump is connected with water tank, and water tank is arranged on the body, and the delivery port of high pressure liquid pump pipeline respectively connects atomizer; Described atomizer is arranged on the front portion of digging arm, and the liquid outlet of atomizer is relative with the peristome of Excavating bucket.
In the above-mentioned excavator that has the automatic water spray dust-arrest device, the pipeline between described high pressure liquid pump and the water tank is provided with strainer.
In the above-mentioned excavator that has the automatic water spray dust-arrest device; Described atomizer is arranged on digging arm front end close end bottom feed pipe by along continuous straight runs and forms with the pulverizing nozzle that is arranged on the feed pipe both sides; Two pulverizing nozzles are all towards tilt, and the angle of two pulverizing nozzle central axis is 5～15 °; Total water smoke overlay area that overlap in the water smoke overlay area of two pulverizing nozzles and two pulverizing nozzles form is greater than the peristome area of Excavating bucket.
In the above-mentioned excavator that has the automatic water spray dust-arrest device; Described pulverizing nozzle is made up of the overcoat, regulating sleeve and the adjustable thimble that connect in regular turn; Be provided with the atomizing spray hole on the coat; Regulating sleeve is threaded with adjustable thimble, and described adjustable thimble is fixed on the pipeline of corresponding atomizer and and pipeline connection.
In the above-mentioned excavator that has the automatic water spray dust-arrest device, the droplet degree of described atomizing spray hole ejection is about 50～100 μ m, and the bore dia of said atomizing spray hole is the nozzle of 1.8mm, and range is 5～15 meters.
After the present invention adopts said structure,, on the pressure distributor that directly adopts excavator to carry simultaneously the high pressure liquid pump power is provided on digging arm through the atomizer of water smoke dust suppression is set, simple in structure, easy to connect.Excavator can produce very big open dirt source when digging operation and batch turning.Minute water molecule through high-pressure atomization combines with airborne dust, and it is moistening that the dust that hikes up is made moist, and gains in weight, and falls go back to the original place immediately, has reduced dust raising phenomenon widely, reaches anti-dust effect.If use in the absence of water smoke dust suppression, the following dust of 75 μ m that hikes up needs certain hour just can fall go back to ground or the contaminated environment of in air, drifting about, and the dust below the 10 μ m also can suck the human lung, causes anthraco-silicosis etc.
Pulverizing nozzle among the present invention is an adjustable nozzle; Spray angle can be regulated according to large, medium and small different excavators, because employing is the high-pressure pump atomizing, the droplet degree that is sprayed is about 50～100 μ m; Adopting bore dia simultaneously is the nozzle of 1.8mm; Range makes spraying water consumption hourly be about 0.8 ton in 5～15 meters, in the time of guaranteeing excavator operation the dust that hikes up is effectively covered inhibition.Conserve water resource is not effectively destroyed the structure of matter of material, especially at coal industry; Can effectively prevent the loss of coal calorie, and can not cause secondary environment pollution, and randomness, continuation are good; Thereby practiced thrift a large amount of cost of production; Reduce resource consumption, reached the dust suppression purpose, protected surrounding enviroment and personal safety.
