Abstract
The utility model relates to a bidirectional drill bit blade device of a deep cement mixing pile machine. The bidirectional drill bit blade device is used for solving the problem that the traditional drill bit blade devices are in unidirectional mixing and cannot realize bidirectional mixing. The bidirectional drill bit blade device of the deep cement mixing pile machine comprises an upper drill rod (2) and a lower drill rod (9), wherein the upper drill rod and the lower drill rod are connected through threads, are provided with through holes and are fixedly connected through enabling a pin 7 to pass through the through holes, the upper drill rod is provided with a blade I (1), a blade II (3), a blade III (5) and a blade IV (6), the lower drill rod is provided with a blade V (10), a blade VI (13), a blade VII (8) and a blade VIII (12), each blade is provided with cutting teeth (4), and the lower end of the lower drill rod is provided with a nib (11). The utility model is applied to the bidirectional drill bit blade device of the deep cement mixing pile machine.
Description
technical field:
the utility model relates to a kind of two-way deep cement-mixed pile machine drill head lobe sheet devices.
background technology:
deep cement-mixed pile machine is more and more subject to people's application at present, its bit blades device also occurs thereupon, but traditional bit blades device is unidirectional stirring, can not realize two-way stirring, rely on self gravitation to enter bearing stratum through mud very soon at work progress king-pile machine drill head, but while arriving bearing stratum, drill bit enter slowly simultaneously, thereby affect operating efficiency, incur loss through delay the duration.
summary of the invention:
the purpose of this utility model is to provide a kind of two-way deep cement-mixed pile machine drill head lobe sheet devices.
above-mentioned object realizes by following technical scheme:
a kind of two-way deep cement-mixed pile machine drill head lobe sheet devices, its composition comprises: upper drilling rod, lower drilling rod, between described upper drilling rod and lower drilling rod, adopt and be threaded, described upper drilling rod and lower drilling rod have through hole, described upper drilling rod is fixedly connected with through through hole by pin with lower drilling rod, on described upper drilling rod, there is blade one, blade two, blade three, blade four, on described lower drilling rod, there is blade five, blade six, blade seven, blade eight, on described blade, have cutting teeth, described lower drilling rod lower end has tip.
described two-way deep cement-mixed pile machine drill head lobe sheet devices, described blade one is corresponding with blade two, described blade one, blade two differ 15 ° each other, described blade three, blade four is vertically positioned at blade one, blade two lower ends, described blade three, blade four differ 15 ° each other, described blade five, blade six and blade one, blade two are parallel, described blade seven, blade eight and blade three, blade Siping City row.
the beneficial effects of the utility model:
1. the utility model is provided with blade on drilling rod, between blade, become to have certain angle simultaneously, and upper drilling rod, lower drilling rod, blade rotation direction can be identical, also can instead fill, can realize the multiple stir mode such as the two-way stirring of bull stick or the turbulent flow stirring of liquid stream, make the more abundant of stirring, below blade, be provided with cutting teeth and improved like this ability of boring, make the function of existing stirring, the function that has again boring, has improved operating efficiency.
the utility model drilling rod is divided into upper and lower two drilling rods, after employing is threaded, be fixedly connected with by pin again, reversion can not be threaded off, and can realize two-way stirring, makes the more abundant of stirring, can realize like this and changing conveniently, be convenient to dismounting, install, and can make drilling rod lengthen the mixing effect that improves different depth.
the utility model is simple in structure, easy to operate, can well increase work efficiency.
brief description of the drawings:
accompanying drawing 1 is structural representation of the present utility model.
detailed description of the invention:
embodiment 1:
a kind of two-way deep cement-mixed pile machine drill head lobe sheet devices, its composition comprises: upper drilling rod 2, lower drilling rod 9, between described upper drilling rod and lower drilling rod, adopt and be threaded, described upper drilling rod and lower drilling rod have through hole, described upper drilling rod is fixedly connected with through through hole by pin 7 with lower drilling rod, on described upper drilling rod, there is blade 1, blade 23, blade 35, blade 46, on described lower drilling rod, there is blade 5 10, blade 6 13, blade 78, blade 8 12, on described blade, have cutting teeth 4, described lower drilling rod lower end has tip 11.
embodiment 2:
according to the two-way deep cement-mixed pile machine drill head lobe sheet devices described in embodiment 1, described blade one is corresponding with blade two, described blade one, blade two differ 15 ° each other, described blade three, blade four is vertically positioned at blade one, blade two lower ends, described blade three, blade four differ 15 ° each other, described blade five, blade six and blade one, blade two are parallel, described blade seven, blade eight and blade three, blade Siping City row.
