The purpose of this utility model is to provide a kind of can make the effective dust suction of cleaning chew device.

The purpose of this utility model can reach by following measure: the utility model comprises that a box-like is inhaled and chews body, before body is chewed in this suction, fastening respectively on three sides, back a slide block is installed, inhale a hinged drawbar on the bearing chew the body end face being positioned at box-like, it is characterized in that connecting with flexible drinking straw between the conduit on box-like is inhaled the suction pipe chew body and is fixed in vehicle frame, box-like is inhaled the other end of chewing drawbar hinged on the body end face bearing and the drawbar bearing that is fixed on the vehicle frame and is adopted everything cross hinge connection, be connected with a wire rope on drawbar, the other end of this wire rope links by assembly pulley and the lift cylinder that is fixed on the vehicle frame; Inhale at box-like and to chew body along this suction in the dust suction chamber chew between intracoelomic cavity and the ground one flexible ligulate front apron vertically is installed; Inhale at box-like and to chew on the body end face in right front slide block one side to empty chamber in half cone is arranged between the suction pipe.

Fig. 1 is the utility model structural representation front view;

Fig. 2 is the mansion view of Fig. 1;

Fig. 3 is an A--A sectional view among Fig. 2.

The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment:

In Fig. 1,1 inhales for box-like and to chew body, chew in suction and fastening respectively on three sides of body 1 a preceding left side is installed, the preceding right side and

rear slider

4,16,17, inhale a hinged drawbar 5 on the bearing 6 chew body 1 end face being positioned at, the suction pipe 15 of chewing body 1 in suction be fixed in vehicle frame on conduit 3 between use flexible drinking straw 2 to connect, the other end of suction being chewed drawbar 5 hinged on body 1 end face adopts everything cross axle 7 hinge connection with the drawbar bearing 10 that is fixed on the vehicle frame, on drawbar 5, be connected with a wire rope 8, the other end of this wire rope 8 links by assembly pulley 18 and the lift cylinder 19 that is fixed on the vehicle frame, among Fig. 3, inhaling 13 li of the dust suction chambers chew between body 1 inner chamber and the ground at box-like chews body 1 a flexible ligulate front apron 11 vertically is installed along inhaling, among Fig. 2, chewing in suction has empty chamber 14 in half cone between suction pipe 15 and preceding right slide block 16 on body 1 end face, so promptly constitute the designed dust suction of the utility model and chew device.The utility model operating principle is as follows: before adjusting,

rear slider

4,16,17 make it contact with ground, regulate ligulate front apron 11 and suction and chew the back base plate 12 of body 1 and the spacing on ground, suction is chewed body 1 by conduit 3, drawbar bearing 10 and lift cylinder 19 connect with vehicle frame, during work, suction is chewed body 1 along the sweeping machine direction of advance, with moved further and clean, when the direction of advancing runs into the road surface landform when uneven, bump portion or jack-up front-

slider

4 or 16 or jack-up rear slider 17, or two slide blocks of while jack-up, at this moment, owing to inhale between the suction pipe 15 chew body 1 and the conduit 3 and connect with flexible drinking straw 2, wire rope 8 is can be flexible, and drawbar 5 adopts everything cross hinge connection with drawbar bearing 10 in addition, this make drawbar 5 can about, left-right rotation, thereby inhale chew body 1 and ground distance everywhere deformationization and floating change, keeping its distance with ground is certain value, promptly inhales to chew body 1 one side by jack-up, another side then can descend, and makes that to inhale the dust suction distance chew body 1 constant.Design a box-like suction in suction pipe 15 lower ends and chewed body 1, be installed on and inhale the flexible front apron 11 and its formation dust suction chamber 13 of chewing body 1 inner chamber, because baffle plate 11 is little with ground distance, thereby dust suction chamber 13 forms a narrow gas channel with ground, enters dust suction chamber 13 and wraps up in the negative-pressure air-flow of band rubbish and obtain higher speed thereby make.And, when running into cobble, brick etc.,, make the bigger foreign material of volume can enter dust suction chamber 13 smoothly because resilient tongue front apron 11 can freely bounce back than bigger material, make again simultaneously the negative-pressure air-flow maintenance that enters dust suction chamber 13 same at a high speed; Because chewing body 1, suction is in asymmetric position with suction pipe 15, thereby chew on body 1 end face in slide block 16 1 sides to being manufactured with empty chamber 14 in half cone between the suction pipe 15 in suction, and small end is near slide block 16, big end connects suction pipe 15, air velocity in order to balance dust suction chamber 13 left and right two ends, make the negative-pressure air-flow speed whole machine balancing in the dust suction chamber 13, pick-up performance is asymmetric and inconsistent because of suction pipe 15 not.

The utility model has following advantage compared to existing technology:

1, since suction is chewed that body is designed to can be with different variation of floating of landform height, consistent with the distance on ground to keep suction to chew body, thereby the effect of cleaning the road surface is not affected by it because of the out-of-flatness on road surface.

2, since adopted box-like to inhale to chew body and within it in the dust suction chamber between chamber and the ground design and installation one flexible ligulate front apron arranged, thereby in dust suction chamber, can form a narrow gas channel, thereby make dust suction chamber produce the negative pressure high velocity air that acts on ground, can make the cleaning effect better like this.

3, between slide block one side and suction pipe, be manufactured with empty chamber in half cone on the body end face owing to chewing in suction, but the air velocity at two ends, the balance dust suction chamber left and right sides, thereby in the time of can solving cleaning work, suction is chewed body by behind the road surface, obviously descending away from suction pipe one end pick-up performance, staying the problem that a band silt particle suction is not entered.
