The device comprises a cylindrical housing, a connecting piece, a screw shaft, and a drill bit. The device is characterized in that the connecting piece is fixedly connected with the upper end of the screw shaft; the lower end of the screw shaft is fixedly connected with the drill pit; the lower part of the screw shaft is connected with a screw blade; the other end of the screw blade is fixed on an inner wall of the housing; the screw shaft and the screw blade are both located in the housing; the connecting piece is located above the housing; the drill bit is located under the housing; and the bottom of the housing is provided with a sawteeth. The beneficial effects of the utility model are that the device is simple in structure and convenient to use, is used along with a pile driver, and can achieve the mechanization of the construction of a concrete foundation in a process of the construction of the photovoltaic power station, so as to shorten the construction cycle of the concrete foundation in the construction of the photovoltaic power station and bring great convenience to the construction of the photovoltaic power station.
Description
Technical field
The utility model relates to photovoltaic plant construction field, particularly a kind of photovoltaic plant foundation pit excavating gear.
Background technology
Photovoltaic plant is in process of construction, and the concrete pedestal construction period is longer, because foundation pit hole size is less, large-scale excavation machinery cannot use, and only can use at present the instrument constructions such as spade, and it is more that manpower expends, require great effort time-consuming, affected the construction period of photovoltaic plant.
Summary of the invention
For the problems referred to above, the utility model, in order to make up the defect of prior art, provides a kind of photovoltaic plant simple in structure, easy to use foundation pit excavating gear.
The utility model is achieved by the following technical solution:
A kind of photovoltaic plant foundation pit excavating gear, comprise cylindrical housing, connector, helical axis, drill bit, it is characterized in that: described connector is fixedly connected with the upper end of helical axis, the lower end of described helical axis is fixedly connected with drill bit, and the bottom of helical axis is connected with helical blade, and the other end of helical blade is fixed on the inwall of shell, described helical axis and helical blade are all positioned at enclosure, connector is positioned at shell top, and drill bit is positioned at shell below, and sawtooth is arranged at the bottom of described shell.
Described shell, connector, helical axis, helical blade, drill bit, sawtooth all adopt high rigidity and high-intensity steel material.
The internal diameter of described shell is identical up and down, and lower outer diameter is greater than the cylindrical shape of top external diameter, is convenient to push the soil of shell below, reduces the frictional force of shell and soil.
The beneficial effects of the utility model are: this photovoltaic plant is simple in structure, easy to use with foundation pit excavating gear, be combined with pile driver, can realize the mechanization that in photovoltaic plant process of construction, concrete pedestal is built, to shorten the construction period of concrete pedestal in photovoltaic plant construction, for the construction of photovoltaic plant brings very large facility.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is the structural representation of a kind of photovoltaic plant of the utility model foundation pit excavating gear;
In figure, 1 shell, 2 connectors, 3 helical axis, 4 helical blades, 5 drill bits, 6 sawtooth.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.A kind of photovoltaic plant foundation pit excavating gear, comprise cylindrical housing 1, connector 2, helical axis 3, drill bit 5, it is characterized in that: described connector 2 is fixedly connected with the upper end of helical axis 3, the lower end of described helical axis 3 is fixedly connected with drill bit 5, the bottom of helical axis 3 is connected with helical blade 4, the other end of helical blade 4 is fixed on shell 1, described helical axis 3 and helical blade 4 are positioned at shell 1 inside, connector 2 is positioned at shell 1 top, drill bit 5 is positioned at shell 1 below, and sawtooth 6 is arranged at the bottom of described shell 1; Described shell 1, connector 2, helical axis 3, helical blade 4, drill bit 5, sawtooth 6 all adopt high rigidity and high-intensity steel material; Described shell 1 is that internal diameter is identical up and down, and lower outer diameter is greater than the cylindrical shape of top external diameter, is convenient to push the soil of shell 1 below, reduces the frictional force of shell 1 and soil.When use, connector 2 is fixed on pile driver, rotation starts, and helical axis 3 rotates, thereby drives helical blade 4 and shell 1 to rotate, and the sawtooth 6 of shell 1 bottom cuts out foundation pit hole profile, and drill bit bores and excise soil in hole, hole for 5 times.
