Description
Technical Field
The utility model belongs to the technical field of foundation treatment, and particularly relates to a single-shaft stirring drill capable of being installed on a digging machine.
Background
In recent years, foundation treatment technology is rapidly developed, and particularly in coastal and river-along areas, the application of cement mixing piles in soft soil treatment is also becoming wider and wider. However, the traditional cement mixing pile body is large in volume, inconvenient to move, high in site requirement, low in construction efficiency and not suitable for shallow solidification. While the conventional solidification stirring head is suitable for shallow solidification, when a thicker sand layer exists on the upper part, the stirring head is difficult to drill down, and solidification treatment can not be carried out on sludge on the lower part of the sand layer.

In order to solve the technical problems, the utility model provides a single-shaft stirring drill which can be installed on a digging machine.
The technical scheme adopted by the utility model is as follows:
a single-shaft stirring drill capable of being installed on a digging machine comprises a connecting frame, a driving head, an adapter flange, a grouting flange, a drill rod, stirring blades, a spiral cutter head, a slurry spraying port and an alloy blade. The small arm of the excavator is connected with the connecting frame through pins, the connecting frame is connected with the hydraulic driving head through pins, the driving head is connected with the drill rod through an adapter flange and a grouting flange, and the drill rod is connected with the stirring blade, the spiral cutter head and the alloy blade through welding.
The single-shaft stirring drill capable of being installed on the excavator is characterized in that: the connecting frame is formed by welding high-strength steel, and the size of the connecting frame is customized according to the specific model and specification of the excavator;
the single-shaft stirring drill capable of being installed on the excavator is characterized in that: the driving head consists of a hydraulic motor, a speed reducer and a cylindrical steel shell, wherein the hydraulic motor and the speed reducer are fixed in the cylindrical steel shell, the power source of the driving head is a hydraulic system of the excavator, a hydraulic oil pipe at the small arm of the excavator is required to be connected with the hydraulic motor, and the model of the hydraulic motor is selected according to the requirement of a construction soil layer on torque.
The single-shaft stirring drill capable of being installed on the excavator is characterized in that: the adapter flange is connected with the driving head by a pin.
The single-shaft stirring drill capable of being installed on the excavator is characterized in that: the adapter flange is connected with the grouting flange through high-strength bolts.
The single-shaft stirring drill capable of being installed on the excavator is characterized in that: the grouting flange is connected with the drill rod through a high-strength bolt.
The single-shaft stirring drill capable of being installed on the excavator is characterized in that: the drill rod is welded with the stirring blade, the spiral cutter head and the alloy blade.
The single-shaft stirring drill capable of being installed on the excavator is characterized in that: the two spraying openings are 180 degrees away from each other and are positioned on the drill rod between the spiral cutter head and the alloy blade.
The beneficial effects of the utility model are as follows: the digging-changed single-shaft stirring drill can be arranged on the digging machine, so that the situation that the traditional stirring pile is slow in moving speed is effectively improved; the spiral cutterhead is additionally arranged at the bottom of the drill rod, and the spiral cutterhead has the advantages of capability of actively pushing down, capability of easily penetrating through a sand layer, convenience in construction, high efficiency, low construction cost, good stirring effect and the like, and is a main trend of current soft soil shallow layer treatment.
