Abstract

The utility model relates to a dredger which is composed of a handle, an end cover, a connecting rod, a piston, a spiral head cover, a pump and dirt sucking discs. The utility model is characterized in that the side edge of one dirt sucking disc is provided with an outer disc edge, the lower part of the dirt sucking disc forms a concave arc-shaped frustum, the diameter of the bottom circle of the arc-shaped frustum is small than the outer diameter of the outer disc edge, and the whole dirt sucking disc presents a hollow shape; the disc edge of the other dirt sucking disc presents a truncated cone shape, the lower part of the dirt sucking disc presents an outwards convex arc-shaped frustum, and the inner part of which forms a hollow shape. When the dredger is used for dredging dirt of pipelines, the dirt sucking discs can be selected according to the caliber sizes of the pipelines, and the utility model has the advantages of convenient assembly and disassembly, wear resistance and good vacuum sucking and sealing effect.

Description

A kind of dredger

The utility model relates to a kind of dredger, and it is specially adapted to the dredging pipeline dirt and stops up, and blowdown is used.

Along with improving constantly with the further family of residential Building Design of people's living standard is idealized, the dwelling house suite that many residents have lived in to have a whole set of house facility and had separate rooms such as bathtub, water closet or many toilets, yet the thing followed is dirts such as pipeline, water closet, wash bowl stops up the problem of handling, and existing on the market at present mediation blowdown apparatus generally is only applicable to single uses such as water closet, pipeline or wash bowl, and because sealing is not ideal enough, cause dirt sewage leakage phenomenon in using.

The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, provides a kind of according to different bores, different needs, and detachable, the replacing of soil pick-up dish, and tightness increasing vacuumize the better dredger of effect.

The technical solution of the utility model 1 is finished like this: this dredger is made up of handgrip, end cap, connecting rod, piston, spiral shell skull, inflator and soil pick-up dish, it is characterized in that soil pick-up dish side has outer rim, the bottom is indent arc frustum, arc awl garden, the end is directly through littler than outer rim external diameter, and whole sucker is hollow shape.A sealing ring is equipped with at its end cap central bore place.

Technical scheme 2 is finished like this: this dredger is made up of handgrip, end cap, connecting rod, piston, spiral shell skull, inflator and soil pick-up dish, it is characterized in that soil pick-up dish connector is the Cylinder shape, interior is thread cavity, the connector middle and lower part is fixedly connected with a truncated cone shape rim, and the bottom is outer convex frustum.A sealing ring is equipped with at its end cap central bore place.

The utlity model has following advantage: moulding gently becomes generous and exquisite, detachably changes according to different bores, different needs soil pick-up dish, and vacuumizes, and tightness strengthens, and the mediation dirt stops up better effects if, and end cap central bore installs sealing ring additional, and more wear-resistant.

Fig. 1 is the utility model structural representation.

Fig. 2 is the little soil pick-up dish of a utility model structural representation.

Now further describe embodiment 1 in conjunction with Fig. 1: this delivery apparatus is made up of handgrip (1), end cap (2), connecting rod (3), piston (4), spiral shell skull (8), inflator (7) and soil pick-up dish (5), it is characterized in that soil pick-up dish (5) side has outer rim, the bottom is indent arc frustum, circle is directly through littler than outer rim external diameter at the bottom of the arc frustum, whole sucker is hollow shape, and a sealing ring (6) is equipped with at its end cap central bore place.

Now further describe embodiment 2 in conjunction with Fig. 2: this delivery apparatus is made up of handgrip (1), end cap (2), connecting rod (3), piston (4), spiral shell skull (8), inflator (7) and soil pick-up dish (9), it is characterized in that soil pick-up dish (9) connector is the Cylinder shape, interior is thread cavity, the connector middle and lower part is fixedly connected with a truncated cone shape rim, the bottom is outer convex frustum, interior is hollow shape, and a sealing ring (6) is equipped with at its end cap central bore place.

When this device is installed, earlier piston (4) and connecting rod (3) cheek are adhesively fixed to reserve and insert in the inflator (7), cover end cap (2), sealing ring (6) being contained in then is adhesively fixed inflator (7) and end cap (2) on the end cap central bore again reserves, load onto handgrip (1), handgrip (1) and connecting rod (3) are gluing fixing and reinforce by screw, then spiral shell skull (8) being inserted in inflator (7) lower port is adhesively fixed and reserves, spiral shell skull (8) front end has a threaded plug and the corresponding grafting of soil pick-up dish connector endoporus cavity, and soil pick-up dish connector internal cavity also is screw-like.Grafting effect like this is better, and sealing ring (6) is contained in end cap central bore, and connecting rod can reduce the phase mutual friction during upper and lower motion in inflator (7), increase the service life, end cap (2) side also has a spilehole, and it is used to get rid of the interior air of tube when moving up and down as connecting rod.

When using this device, as long as according to the unimpeded object, select to use, as when being used for water closet, as long as being packed into spiral shell skull plug, soil pick-up dish (5) connector fixes, then the arc vertebra platform with soil pick-up dish (5) bottom aligns the mouth of a river under the insertion water closet, because mouth of a river curved surface is irregular under the water closet, arc vertebra platform is that soft rubber is made, and the arc vertebra platform and the tightness at the following mouth of a river are strengthened, and the vacuum draw effect is better, earlier push away handgrip downwards this moment, drivening rod, piston is discharged air, then upwards lifts, make in the arc vertebra entablature, after producing certain vacuum in place, the mouth of a river and the spiral shell cranian cavity under the water closet, make the obstruction dirt loosening therefrom, push away so down, lift the dirt of back obstruction several times and promptly get rid of mediation.When dredging large pipeline in this way,, it is pressed along the dish internal diameter, then the outer rim of side is aligned pipeline opening and operate, push away, lift handgrip down, stop up dirt and can get rid of according to said method as long as the arc vertebra platform of soft rubber part upwards is pressed in the soil pick-up dish (5).

Remove wash bowl or washbowl when using this device, or down during the little pipeline opening in the mouth of a river, as long as soil pick-up dish (5) is unloaded, according to soil pick-up dish (5) insertion method soil pick-up dish (9) and spiral shell skull front end plug are aligned grafting and get final product, then again convex vertebra platform hollow position outside soil pick-up dish (9) bottom is aligned under the pipeline and push away under the handgrip of the mouth of a river, then lift and make sucker (9) internal cavity, also has the certain vacuum degree in the spiral shell skull cavity, and make the obstruction dirt loosening, thus blowdown, dredging pipeline.
