The working principle is as follows: the utility model discloses when using, at first start-up pneumatic cylinder 2, make the flexible end of pneumatic cylinder 2 withdraw into to the at utmost, at this moment the flexible end of pneumatic cylinder 2 can drive box 3 simultaneously and descend, 3 tops of box can separate with apron 12, add the clear water in box 3 through 3 open-top of box this moment, watered volume will exceed filter screen 9, then at control pneumatic cylinder 2, make the flexible end of pneumatic cylinder 2 extend to the at utmost, at this moment box 3 can get back to the normal position, 3 tops of box can laminate with apron 12, then start-up water pump 7 respectively, motor 20, first motor 26, second motor 38 and third motor 38, can accomplish preparation work like this. After the above work is done, the construction waste to be screened is poured into the first funnel-shaped barrel 30 through machinery or manual work, in the process, water in a tap water pipe enters the water pipe 32 through the first connecting hose 35 and the first connecting pipe 33, the water in the water pipe 32 is sprayed towards the opening direction of the top of the first funnel-shaped barrel 30 through the plurality of first spray nozzles 34, so that dust generated when the construction waste is poured into the first funnel-shaped barrel 30 is effectively inhibited by the water sprayed by the first spray nozzles 34, a large amount of dust generated in the process of pouring the construction waste is prevented from influencing the natural environment, the construction waste enters the first funnel-shaped barrel 30 and then enters the first barrel body 25 through the bottom end thereof, in the process, the rotating shaft 27 is driven by the first motor 26 to rotate, and the four partition plates 28 on the rotating shaft 27 also rotate along with the rotating shaft 27, so that the construction waste rotates along with the four partition plates 28 after entering the

28, every two opposite partition plates 28 in the four partition plates 28 alternatively block the first cylinder 25, thus, the dust generated when the construction waste enters the funnel-shaped guide cylinder 40 through the funnel-shaped cylinder 24 is not discharged to the outside through the first cylinder 25 and the first funnel-shaped cylinder 30, which effectively prevents the dust generated during the operation of the device, the construction waste entering the funnel-shaped guide cylinder 40 enters the second cylinder 41 through the bottom end thereof, during the process, the second motor 38 drives the second cylinder 41 to rotate in the first cylinder 37 through the gear 39 and the first gear 46, and the first cylinder 37 and the second cylinder 41 are both arranged obliquely, so that the construction waste entering the second cylinder 41 can roll down along the inner inclined plane thereof, and the construction waste rolls along the second cylinder 41, in the process, the powdery and small building wastes fall into the first barrel 37 between the two rotary rings 42 through the first through holes 45, the powdery and small building wastes falling into the first barrel 37 are collected in the second funnel-shaped barrel 48, the plurality of baffles 47 arranged in the second barrel 41 can block the falling building wastes to a certain extent, the building wastes are prevented from rapidly falling from the second barrel 41, the time for the building wastes to fall in the second barrel 41 in a rolling manner is prolonged, the powdery and small building wastes in the building wastes can be screened out fully, most of the building wastes falling from the second barrel 41 are large in size, and the powdery and small building wastes in the building wastes are separated, so that a large amount of dust can not be generated when the building wastes finally fall from the second barrel 41, and the purpose of environment-friendly screening of the building wastes is effectively achieved, in the process of rolling and screening the powdery and small pieces of construction waste in the construction waste by the second cylinder 41, the motor 20 drives the fan 21 to rotate at high speed, the fan 21 blows air into the box body 3 when rotating, the water pump 7 discharges the water in the box body 3 into the annular box body 14 through the drain pipe 11, the connecting hose 17 and the connecting pipe 15 in sequence, the water entering the annular box body 14 is sprayed out through the plurality of spray heads 16, so that the dust generated when the construction waste rolls in the second cylinder 41 and the dust generated between the second cylinder 41 and the first cylinder 37 are blown into the box body 3 through the first through holes 45, the through holes 43 and the barrel body 22 in sequence under the air suction effect of the fan 21, the dust blown into the box body 3 can be effectively dissolved in the water in the box body 3 under the effect of the water mist sprayed out by the plurality of spray heads 16, and the dust generated in the process of rolling and screening the construction waste by the second cylinder 41 is effectively prevented from being discharged to the outside, the dustproof purpose of this device has further been improved to because orifice plate 8 and filter screen 9's setting, the particulate matter of the interior aquatic adulteration of box 3 can be blockked on filter screen 9, and the aquatic of orifice plate 8 lower extreme can not mix too much particulate matter, consequently can not produce harmful effects (for example block up) to water pump 7 and shower nozzle 16, therefore the water in the box 3 can be used cyclically for a long time, the effectual water resource of having practiced thrift. When the powdery and the building waste of fritter in the second infundibulate section of thick bamboo 48 are discharged, connect material receiving container (box) at the discharge end of a row of material section of thick bamboo 50 in advance, then restart third motor 51, auger 52 can be slow like this pass through the discharge end of a row of material section of thick bamboo 50 the powdery and the building waste of fritter in the second infundibulate section of thick bamboo 48 and discharge, the raise dust that produces when the building waste that can effectual reduction powder and fritter is derived like this.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
