Abstract
The auger bin consists of drilling rod and bin body, the drilling rod has upper connecting part and lower spiral auger part extending out the bin body, and the bin body has frame fixed onto the drilling rod, door hinged to the frame. The bin body has low conic surface, and there is cutting auger in the side of the frame and the low conic surface. The lower conic surface of the door has feeding port and feeding door to enclose the feeding port, and the upper surface of the bin body has air outlet. The spiral auger has powerful drilling capacity and soil exhausting capacity and has centering effect for other cutter to act fully, so that it is especially suitable for drilling in hard foundation.
Description
The present invention relates to a kind of auger bin for deposited-pile hole.
The construction tool that the construction of hole for grout pile has several different methods and matches with these methods, auger bin for deposited-pile hole is exactly a kind of in these construction tools, it has that a confession with drilling rod rotation is entered by the earth of drilling bucket drilling and with its bucket body that holds, therefore, this auger bin for deposited-pile hole had both had the function of boring, has the function that fetches earth again, but, present this auger bin for deposited-pile hole only is adapted to the construction of the hole for grout pile on the subgrade, then there is drilling ability in the construction of the hole for grout pile on the hard place base a little less than, the slow problem of speed of application.
The purpose of this invention is to provide a kind of auger bin for deposited-pile hole of on the hard place base, constructing of also being adapted to.
Solution of the present invention is the part formation awl augers that bucket body is stretched out in the lower end of drilling rod.
Above-mentioned awl augers has saturating performance of very strong brill and casting performance, therefore, it adapts to holes on the hard place base, and can improve speed of application, in addition, creep into back awl augers whole drilling bucket is also played the centering effect, the cutter tip that is installed on the bucket body can be played one's part to the full, thereby also improved penetration rate.According to test, speed of application has improved 33%.
Illustrate particular content of the present invention below in conjunction with drawings and Examples.
Fig. 1; Structure chart of the present invention;
The lateral view of Fig. 2: Fig. 1.
As shown in the figure, auger bin for deposited-pile hole of the present invention is entered by the earth of drilling bucket drilling and the bucket body that it holds is formed by drilling rod 1 with the confession of drilling rod 1 rotation, wherein the upper end of drilling rod 1 forms connector 2, the part that bucket body is stretched out in the lower end forms awl augers 3, bucket body has the bucket frame 4 that is fixed on the drilling rod 1 and divides a left side that is located at bucket frame 4, right also with bucket frame 4 hinged sluice gates 5,6, and the lower surface of bucket body forms the conical surface, the side 7 of bucket frame 4,8 and the following conical surface 9, cutter tip 11 is housed on 10,12 and 13,14, sluice gate 5,6 the following conical surface 15,16 are provided with charging aperture 17,18 and with the following conical surface 15,16 hinges connect and with charging aperture 17, the feeding gate 19 of 18 sealings, 20, the upper surface of bucket body is provided with steam vent 21,22.Present embodiment also is designed to the conical surface with the upper surface of bucket body, and steam vent is located in 21,22 minutes on the last conical surface 23,24 of sluice gate 5,6.Present embodiment respectively is provided with three cutter tips 11,12 in the position, upper, middle and lower of the side 7,8 of bucket frame 4, on the following conical surface 15,16 of bucket frame 4 three cutter tips 13,14 is set respectively also from inside to outside. Feeding gate 19,20 is hinged doors that a fan is inwardly opened, when the drilling bucket rotary drilling, feeding gate 19, the 20 drilled earth that are in motion state that chip away are pushed open, creep into when stopping to mention drilling bucket, 19,20 of feeding gates are closed under the effect of gravity automatically, prevent that the earth in the bucket body from spilling from charging aperture 17,18.Drilling rod 1 connects by the output shaft of connector 2 with unit head, and present embodiment is designed to latch interconnection system structure with connector 2.Sluice gate 5,6 should be fixed after closing up with bucket frames 4, and present embodiment adopts hinge to buckle 25 fixed structures that add latch 26.Awl augers 3 and cutter tip 11,12,13,14 design according to the structural theory and the experimental data of cutting tool, in the present embodiment, awl augers 3 is a welded construction, be welded with helical blade 27 by drilling rod 1, and adopt coarse pitch, varying pitch, the wide structure of change leaf, i.e. the pitch S of auger shell rotary drill head 3
2＞S
1, the helical blade width is big from little change from bottom to top, and in addition, the end cutting edge welds chimeric golden cutter head.
Claims (2)
1, a kind of auger bin for deposited-pile hole, entered by the earth of drilling bucket drilling and the bucket body that it holds is formed by drilling rod with the confession of drilling rod rotation, wherein the upper end of drilling rod forms connector, bucket body has the bucket frame and the branch that are fixed on the drilling rod and is located at a bucket frame left side, right also with the hinged sluice gate of bucket frame, and the lower surface of bucket body forms the conical surface, on the side of bucket frame and the following conical surface cutter tip is housed, the following conical surface of sluice gate is provided with charging aperture and is connected with following conical surface hinge and with the feeding gate of charging aperture sealing, it is characterized in that: the part that bucket body is stretched out in the lower end of drilling rod (1) forms bores augers (3).
2, auger bin for deposited-pile hole according to claim 1 is characterized in that: awl augers (3) is coarse pitch, varying pitch, the wide awl augers of change leaf.
