Grid sewage-removing machine adopts fixed grid to stop, the structure formation that relies on circulation rake teeth to salvage garbage waste material because rake teeth needs cycle operation, has therefore just left space and allowed rake teeth pass through between stationary grizzly and frame.In order to prevent that the floating foreign material of solid from spilling from this space, current domestic employing be that rubber plate sealing or two kinds of patterns of movable rack sealing are processed, rubber plate matter is soft, easily aging, long time running quick abrasion; And movable rack is integrated overturn formula, due to welding distortion, upset etc. back and forth for a long time, the wearing and tearing of its rolling bearing are very fast, and distortion also can make it stuck, and whole plant cannot normally be worked.In addition, because rubber plate or movable rack are positioned at water channel bottom, maintenance need to hang out whole plant or empty mud, the sewage in whole piece water channel, and workload is large, and maintenance cost is high, waste time and energy, and very trouble, and affect the continuous operation of equipment.
Utility model content
The applicant, for above-mentioned problem, is studied improvement, and a kind of grid sewage-removing machine is provided, simple in structure, running is reliable, efficiently tackles garbage waste material in sewage, the maintenance interval of extension device, reduces maintenance workload, ensures the long-time reliability service of equipment.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of grid sewage-removing machine, comprise frame and revolution haulage gear, rake teeth connects described revolution haulage gear, stationary grizzly is arranged on the bottom of described frame, gap location between described frame and described stationary grizzly is provided with a fixing short grid that is positioned at frame upstream face, spacing and the quantity of the grizzly bar of described fixing short grid are identical with spacing and the quantity of the grizzly bar of described stationary grizzly, the angle setting of staggering between described fixing short grid and described stationary grizzly; The lower end of movable grizzly bar is by the be rotatably connected upper end of described fixing short grid of bearing pin, spacing and the quantity of movable grizzly bar are identical with spacing and the quantity of the grizzly bar of described stationary grizzly, the gap location of described movable grizzly bar movable covering between described fixing short grid and described stationary grizzly.
Further:
Form the grizzly bar of described fixing short grid in same plane.
The grizzly bar that the forms described fixing short grid angle setting of staggering.
Technique effect of the present utility model is:
The disclosed a kind of grid sewage-removing machine of the utility model, simple in structure, low cost of manufacture, in frame bottom, fixing short grid and movable grizzly bar are set, movable grizzly bar is lightweight, and every movable grizzly bar can be opened separately or close, rotate flexibly, be difficult for blocking, easy to maintenance, running is reliable, garbage waste material in efficient interception sewage, the maintenance interval of extension device, reduces maintenance workload, ensures the long-time reliability service of equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to enlarged view.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises frame 4 and revolution haulage gear 1, and revolution haulage gear 1 is the main driving mechanism of grid sewage-removing machine, and it comprises motor, speed reduction unit, transmission rig, guide wheel, haulage chain etc., under the driving of motor, haulage chain is made cycle rotation.Stationary grizzly 2 is arranged on the bottom of frame 4, and stationary grizzly 2 adopts band steel to make, and for main conservancy trash machine structure, the rubbish article in the grizzly bar gap that is greater than stationary grizzly 2 is trapped on grizzly bar upstream face.Rake teeth 3 connects the haulage chain of revolution haulage gear 1, and the gear piece that rake teeth 3 is cut into by steel pipe and line forms, and rake teeth 3 is made cycle rotation with the haulage chain of revolution haulage gear 1, and the rubbish thing of in cycle operation, the grid 2 that is fixed being tackled rises to equipment discharge port.Gap location between frame 4 and stationary grizzly 2 is provided with a fixing short grid 5 that is positioned at frame upstream face, fixing short grid 5 adopts band iron to make, also can make with monoblock steel plate or plastic plate, the lower end of fixing short grid 5 is welded on the lower end of frame 4, and spacing and the quantity of the grizzly bar of fixing short grid 5 are identical with spacing and the quantity of the grizzly bar of stationary grizzly 2.The angle setting (as Fig. 1) of staggering between fixing short grid 5 and stationary grizzly 2, that is to say, fixing short grid 5 is not with stationary grizzly 2 in same plane, and between fixing short grid 5 upper ends and stationary grizzly 2 lower ends, still having a gap can pass for the haulage chain of rake teeth 3 and revolution haulage gear 1.The lower end of several movable grizzly bars 7 is rotatably connected and is fixed the upper end of short grid 5 by bearing pin 6, movable grizzly bar 7 band irons are made, spacing and the quantity of the identical grizzly bar with stationary grizzly 2 of the spacing of movable grizzly bar 7 and quantity are identical, the axle head of bearing pin 6 is spacing with back-up ring and split pin, prevent that bearing pin 6 from coming off, the gap location of movable grizzly bar 7 movable coverings between fixing short grid 5 and stationary grizzly 2, the front end of movable grizzly bar 7 is by the cross bar 201 spacing (as Fig. 2) of stationary grizzly 2 lower ends.In the time that rake teeth 3 runs to the gap location between fixing short grid 5 upper ends and stationary grizzly 2 lower ends, backed down upwards and rotated with the movable grizzly bar 7 of rake teeth 3 corresponding positions, after rake teeth 3 passes through, under action of gravity, movable grizzly bar 7 homings, continue to play and stop that rubbish thing acts on, like this, when rake teeth 3 passes through, only have the movable grizzly bar 7 of one or several and rake teeth 3 corresponding positions to be backed down, and remaining movable grizzly bar 7 still rests on original position, both can be for the haulage chain of rake teeth 3 and revolution haulage gear 1 be through space is provided, can prevent that again rubbish thing from passing through from gap location, that is to say, when rake teeth 3 by time, only have monolithic or several movable grizzly bar 7 to open or close, instead of the unlatching of entirety or close, every movable grizzly bar can be opened separately or close, and rotates flexibly, is difficult for blocking, turn round more reliable, the maintenance interval of extension device, the reliability service of guarantee equipment.
Fixing short grid 5 can adopt two kinds of structure formations, when the grizzly bar 501 that forms fixing short grid 5 is in same plane, all movable grizzly bars 7 can adopt the axle of having strong market potential to be connected to the upper end of fixing short grid 5, after also movable grizzly bar 7 can being divided into groups, are connected to short pin shaft the upper end of fixing short grid 5.Stagger angle while arranging when forming the grizzly bar 501 of fixing short grid 5, grizzly bar can be single, two or many be one group of angle setting of staggering, be that three grizzly bars 501 are one group of angle setting of staggering as shown in Figure 1, 2, the upper end of three groups of grizzly bars connects three movable grizzly bars 7 with shorter bearing pin 6 respectively, the grizzly bar 501 angle setting of staggering can reduce the resistance of current, is conducive to the unobstructed of current and flows.
