Abstract
The utility model relates to the improvement of a tooth rake of a grid dirt cleaning machine, which is used for removing solid floating impurity in water. The utility model is characterized in that the peripheries of the metal tooth rake and interval rings are provided with folding edges which are mainly perpendicular. Thus not only the strength of the plane flake tooth rake is effectively strengthened, the service life of the tooth rake is prolonged and the repair of the dirt cleaning machine is reduced but also the quantity of the tooth rake is reduced and the manufacture cost is reduced. A pressed interval cylinder with turning edges can make use of thinner sheet material to process and manufacture the interval rings with wide intervals. The manufacture cost can be reduced. The utility model is particularly suitable for the tooth rake with wide intervals to be used as the interval rings.
Description
Utility model is about the improvement to rotary grid trash rake tooth harrow and space collar.
Remove in feedwater or the sewerage treatment to pick up and get rid of the floating foreign material of solid in the water, adopt the rotary grid trash rake usually.The crux part sheets tooth harrow of rotary grid trash rake should have certain intensity, and is corrosion-resistant again, and weight is lighter again, so tooth harrow adopts plastics or sheet metal to make usually.The plastics tooth harrow mainly exists intensity low, and the use frangibility is damaged, and uses and be subjected to placing restrictions on of temperature, be not suitable for higher or lower temperature environments in use.Though metal plain film tooth harrow intensity increases than the plastics tooth harrow, still not good enough because of tab strength, meeting foreign material too much or have card to block up situation, metal plain film tooth harrow still can bending causes and bumps tooth, seriously can cause arbor to derail; Secondly, the metal plain film is thin, and required compounded plate number is more, has increased the load of equipment, has also increased the complete machine manufacturing cost simultaneously; Thin slice tooth harrow axis hole goes out groove with the arbor grinding easily like blade besides.Plain film tooth harrow combination grid crack forms then adopts metal plain film packing ring, and combination need be adopted the thick sheet metal punching out during big grid crack, even mechanical car's system, and not only manufacture difficulty is big, and consumptive material is many, and cost is big, but also has increased weight of equipment.
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and a kind of improved mechanical strength height is provided, and rotary grid trash rake tooth harrow that again can bigger minimizing tooth harrow quantity.
It is a kind of improved few with material, in light weight that another purpose of utility model is to provide, the tooth harrow space collar that cost is low.
Utility model first purpose realizes that main the improvement is that metal plain film tooth harrow periphery is bent up the formation flanging, and one has improved thin slice tooth harrow intensity; Two to have increased the tooth harrow limit thick, can bigger minimizing tooth harrow consumption during combination, and the increase of monolithic weight is less again, thereby can alleviate complete machine weight.Specifically, utility model grilling trash remover metal tooth harrow is characterized in that said tooth harrow periphery has the stiffened edge of turning up.Be easy manufacturing, the stiffened edge of turning up can be the flanging with tooth harrow side approximate vertical.The further increase of tooth harrow intensity, also can be in the side of tooth harrow vertical or horizontal stamped bumps reinforcing rib, the reinforcing rib bossing especially with towards flanging for well, be more suitable for being used to make up fine grid crack like this.Make through operations such as punching press, flangings by sheet metal with novel tooth harrow.
Utility model second purpose realizes, its improvement is that the space collar with the plane changes the double-deck tube at interval by the metal sheet punching out into, and specifically, utility model grilling trash remover tooth harrow space collar is characterized in that said space collar is the bilayer circle of inside and outside flange in the same way.By sheet metal space collar of constituting of the double-layered cylinder body of flange in the same way inside and outside punching stretch forms, its flanging height is interval width, can use thin metal sheet to make bigger at interval space collar like this, the utility model space collar especially is suitable for the tooth harrow that is assigned in the band flanging.
Description below in conjunction with two non-limiting embodiment further specifies utility model.
Fig. 1 is a utility model tooth harrow example structure schematic diagram.
Fig. 2 is a utility model space collar structural representation.
Fig. 3 is utility model user mode tooth harrow and space collar combining structure schematic diagram.
Embodiment 1: as Fig. 1, tooth harrow 1 is formed by the stainless steel substrates punching out, what its periphery had an approximate vertical turns up limit 2, its axis hole internal circle 3 is also dug and is formed the thickening axis hole, increase and the axle contact surface, minimizing is worn and torn to axle, and the 4 vertical punching presses of tooth harrow side have the reinforcing rib 5 of projection, and reinforcing rib boss and flanging are in the same way.
Embodiment 2: the double-deck space collar 6 of tubular that the punching out of stainless steel thin slice is processed into flanging 7 and in-flanges 8, wherein in-flanges and flanging are in the same way, and be shorter than flanging, the hole that the flanging periphery forms is bigger than the tooth harrow axis hole, and determines the flanging height according to interval width.
The combination of utility model user mode tooth harrow and space collar, referring to Fig. 3, alternate tooth harrow 1, double-deck space collar 6 or the flange cylindrical shell 11 of being installed with on axle 9.Wherein space collar 6 outer rings are placed in outside the tooth harrow 1 flanging axis hole.
Utility model tooth harrow, space collar shape are not limited to accompanying drawing and give, and turning up the limit also can be embowment.
Utility model is owing to sheet metal tooth harrow periphery being turned up and at tooth harrow side plane punching press reinforcing rib, made same base material tooth harrow increase mechanical strength and screen resilience, the not flexible damage of tooth harrow; Secondly, the tooth harrow flanging makes the thick increase in tooth harrow limit can reduce consumption about 40% than Yuanping City's thin slice tooth harrow under identical grid crack, such one has reduced the manufacturing cost of complete machine, two have alleviated the load and the complete machine weight of arbor again, and the gap is big between three tooth harrows, can improve drainage gap.Tooth harrow axis hole flange makes axis hole increase thickness, thereby has overcome the defective that former thin slice tooth harrow axis hole easily grinds arbor groove, has protected arbor to be difficult for being damaged.Double-deck tubular that flanging bends or flange cylindrical shell space collar, with flange width or cylindrical shell height as grid gap length degree, can utilize space collar like this than fine sheet processing and fabricating interval broad, be particularly useful for the broad gap tooth harrow and make space collar, can save space collar with material and cost, to alleviating complete machine weight positive effect be arranged also simultaneously.The utility model space collar especially is suitable for the tooth harrow of band flanging.
For convenience of description, the said gap of utility model, grid crack are synonym, and flange, flanging are synonym.
