Further, described impact rotating device comprises jump bit, drill steel, water filling mandrel and rig, one end of jump bit with stretch in travelling gear, travelling gear drives the drill steel of its inside to rotate, the end of drill steel stretches in water filling mandrel, and water filling core the tip of the axis is connected with drilling tool.
Further, described drilling tool comprises outer tube and inner sleeve, and the top of inner sleeve is arranged in described water filling mandrel, and outer tube is arranged on the one end near water filling mandrel on inner sleeve.
Further, described jump bit is pneumatic striking mechanism or hydraulic impact hammer.
Further, described churning device comprises hydraulic locking grip device and quill shaft, described quill shaft is connected with the output of hydraulic motor by described travelling gear, hydraulic locking grip device is arranged on one end of quill shaft, be provided with churning drilling rod in quill shaft, this churning drilling rod is fixed in described quill shaft by described hydraulic locking grip device.
Further, the utility model can be able to be used alternatingly according to working condition requirement two stations; One group of hydraulic motor transmission can be realized, complete two kinds of construction functions.
By such scheme, the utility model at least has the following advantages: can complete independently construction operation, change churning in traditional construction to run into pebble layer, building waste backfill stratum or seabeach and to rockfill the complicated work progress such as stratum, efficiency of construction is high, cost is low, considerably increase practicality and the flexibility of equipment, the range of application of equipment is increased greatly.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of manual, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is that the utility model double hydraulic pressure percussion-rotary drilling enters, the structural representation of churning unit head.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Shown in Figure 1, a kind of double hydraulic pressure percussion-rotary drilling enters, churning unit head, comprise pedestal 1, described pedestal 1 is provided with impact rotating device 2 and churning device 3, described impact rotating device 2 is connected respectively by the output shaft of travelling gear 4 with hydraulic motor 5 with churning device 3, and hydraulic motor 5 controls the conversion of the station of impact rotating device 2 and churning device 3.
Described impact rotating device 2 comprises jump bit 6, drill steel 7, water filling mandrel 8 and rig 9, one end of jump bit 6 with stretch in travelling gear 4, travelling gear 4 drives the drill steel 7 of its inside to rotate, and the end of drill steel 7 stretches in water filling mandrel 8, and the end of water filling mandrel 8 is connected with drilling tool 9.
Described drilling tool 9 comprises outer tube 10 and inner sleeve 11, and the top of inner sleeve 11 is arranged in described water filling mandrel 8, and outer tube 10 is arranged on the one end near water filling mandrel 8 on inner sleeve 11.
Described jump bit 6 is pneumatic striking mechanism or hydraulic impact hammer.
