Description

A kind of excavator

The utility model relates to a kind of excavation machinery, exactly is a kind of excavator.

At present, mostly the excavating equipment that river course, lake dredging up engineering generally adopt is to have the excavator of bucket, and excacation pushes away, digs action by mechanical arm drive bucket and realizes.Such excavating equipment in use is subjected to the restriction of mechanical arm length, and when being used for desilting under water, the desilting degree of depth is difficult to put in place sometimes, and it is big to excavate the attached engineering quantity that helps of construction, and construction speed is slow, is difficult to satisfy the hydraulic engineering construction needs.

The purpose of this utility model is: a kind of excavator that is suitable for reaching operation in the hazardous environment under water is provided.

Realize that the above-mentioned purpose technical solution is such, a kind of excavator, comprise base 11, framework 12, counter-jib 13, transmission mechanism 14, operating room 15, hoisting mechanism 16 and excavating gear etc., it is characterized in that: excavating gear is made up of spiral digging mechanism, motor 4, outer outlet body 7 and end cap 8, spiral digging mechanism is made up of drill bit 1, rachis 2 and helical blade 3, the leading section of rachis 2 is a drill bit 1, helical blade 3 is a helical form, and from the front portion of drill bit 1 one side windings rachis 2; Be provided with a base plate 6 by bearing on the output shaft 5 of motor 4, the axle head of output shaft 5 is connected with rachis 2; Outer outlet body 7 is a cylindrical drum that connects, and motor 4 and spiral digging mechanism are located in the outer outlet body 7, and drill bit 1 extends outside outer outlet body 7 one ends, and outer outlet body 7 the other end are provided with an end cap 8; Uniform 3 suspension ring on the outer outlet body 7 in the end cap 8 diameters outsides; Cavity between base plate 6 and the blade 3 is locker room 9, with uniform plural drain hole 10 on the sidewall of locker room's 9 corresponding outer outlet bodies 7.

The excavating equipment advantage compared with prior art that this kind has the helical digger structure is:

One, this equipment is suitable for reaching under water and carries out digging operation in the hazardous environment, and the operator is not had any danger;

Two, this equipment can be suitable for the submerged digging operation of different depth, is not subjected to the restriction of mechanical arm length;

Three, this device structure simplicity of design, reasonable, cost of manufacture is low, and is easy to operate.

Fig. 1 is the utility model structural representation,

Fig. 2 is spiral digging mechanism structural representation.

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

As seen from Figure 1, excavator of the present utility model mainly comprises base 11, framework 12, counter-jib 13, transmission mechanism 14, operating room 15, hoisting mechanism 16 and excavating gear 18.

As seen from Figure 2, excavating gear 18 is made up of spiral digging mechanism, motor 4, outer outlet body 7 and end cap 8, and spiral digging mechanism comprises drill bit 1, rachis 2 and helical blade 3.The front portion of rachis 2 is a drill bit 1, spiral blade 3 from drill bit 1 one sides by welding the front portion that fixedly installs around rachis 2.By bearing suit one base plate 6, motor 4 is by being bolted on the base plate 6 on the output shaft 5 of motor 4, and the axle head of output shaft 5 is fixedlyed connected with rachis 2 by bolt.Outer outlet body 7 is a cylindrical drum that connects, and motor 4 and spiral digging mechanism are installed in the outer outlet body 7, and drill bit 1 extends outside the outer outlet body 7, and outer outlet body 7 ends of motor one side are installed with an end cap 8; Uniform 3 suspension ring on the outer outlet body 7 in the end cap 8 diameters outsides.Base plate 6 is along the circumferential direction fixedlyed connected with the sidewall of outer outlet body 7 by bolt.Cavity between base plate 6 and the helical blade 3 is locker room 9, and during operation, the object that drill bit 1 bores pick directly imports locker room 9 by helical blade 3.With uniform nine drain holes 10 on the sidewall of locker room's 9 corresponding outer outlet bodies 7.

During use, excavating gear is installed on the pulley suspension hook 17 by 3 suspension ring on end cap 8 outside outer outlet bodies 7.

When being used for dredge operation, pulley suspension hook 17 is being with excavating gear 18 descending, when arriving the scope of operation, motor 4 is just being changeed, and utilize the weight of excavating gear self to excavate as motive force, the object that has dug enters locker room 9 along helical blade 3, when treating that storing reaches a certain amount of, stop motor 4; Then upgrade excavating gear 18, and after by counter-jib 13 excavating gear being delivered to discharge pit, make motor 4 counter-rotatings, the object in the locker room 9 oppositely draws off along helical blade 3, promptly finishes one-stop operation.Then repeat said process and carry out operation next time.
