Revolve and excavate rock soil-shifting drilling bucket
The utility model belongs to Spiral digging machine drilling bucket field, specifically a kind of Bulldozing mechanism that excavates rock soil-shifting drilling bucket that revolves.
At present, common rotary drilling rig is opened the soil that unloads of rock drilling bucket, mainly moves downward by self gravitation and discharges outside the bucket, sometimes have to employ the instruments such as steel pipe, reinforcing bar, bit by bit dregs is drawn out with manpower, so not only increased labor's labour intensity, also affect operating efficiency.Because China is vast in territory, geological condition is complicated, and is with a varied topography changeable.Owing to the water swelling of clay, it is too closely knit to cause dregs to be clogged in drilling bucket in construction, brings a lot of problems to getting rid of Tu with Dun soil goes out bucket, and shortened dramatically the application life of drilling bucket and corresponding accessory thereof.
Summary of the invention
The purpose of this utility model is to overcome to revolve to excavate the rock drilling bucket and unload native above shortcomings, provides a kind of revolving to excavate rock soil-shifting drilling bucket.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of revolving excavates rock soil-shifting drilling bucket, comprises cylindrical shell and covers at the loam cake on the cylindrical shell, covering the Bulldozing mechanism that can move up and down in cylindrical shell is installed; Described Bulldozing mechanism is comprised of with the push pedal that is installed in two pitman shaft lower ends two pitman shafts that can move up and down that cover on being installed in.
Operating principle is: when carrying on the rig when unloading soil, utilize unit head to the downward extruding earth that presses down pitman shaft and drive push pedal, add simultaneously quick shake and the whipping of drilling rod, acting in conjunction is discharged dregs outside the drilling bucket.
The utility model has the advantages that: owing to increased Bulldozing mechanism, the native efficient of unloading of rock drilling bucket is greatly improved, simple and practical.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model structural scheme of mechanism.
Among the figure: 1, loam cake, 2, upper shell, 3, lower shell, 4, push pedal, 5, pitman shaft, 6, fairlead, 7, adapter sleeve, 8, bolt, 9, packing ring, 10, nut.
The specific embodiment
As shown in Figure 1, revolve and excavate rock soil-shifting drilling bucket and comprise loam cake 1, upper shell 2, lower shell 3 and Bulldozing mechanism.Loam cake 1 is welded on the upper end of upper shell 2, and lower shell 3 has consisted of the whole tubular construction of opening rock soil-shifting drilling bucket; Adding that Bulldozing mechanism just consists of one and excavates rock soil-shifting drilling bucket with revolving of Bulldozing mechanism.Bulldozing mechanism is comprised of with the push pedal 4 that is installed in two pitman shaft 5 lower ends two pitman shafts that can move up and down 5 that are installed on the loam cake 1.Push pedal 4 is connected with pitman shaft 5 electric welding.The position of installing connecting rods axle 5 is equipped with fairlead 6 on loam cake 1, pitman shaft 5 passes fairlead 6, adapter sleeve 7 of its top device, adapter sleeve 7 usefulness bolts 8, packing ring 9, nut 10 pin, prevent that the Bulldozing mechanism downslide from coming off, unload when utilizing unit head to press down in the native process at rotary drilling rig like this, safety and reliability, without the time can conveniently lay down.Pitman shaft 5 slides up and down by fairlead 6 and realizes that Bulldozing mechanism moves up and down and unload soil.
After adopting said method that rotary drilling rig is opened the rock drilling bucket and improved, the native efficient of unloading of drilling bucket is greatly improved, and has improved simultaneously the efficient of creeping into, and has reduced workman's labour intensity, reduces construction noise, the application life of having improved drilling bucket.
