Abstract
The invention relates to a barrel plane type suction-preventing rotary excavating drilling bucket. The barrel plane type suction-preventing rotary excavating drilling bucket comprises a top plate assembly, a barrel, a base plate assembly and an opening-closing mechanism; the top plate assembly is welded to the top of the barrel, the side, provided with a hinge, of the barrel is of a plane structure, a connecting shaft is arranged at the bottom of the barrel, the base plate assembly is connected with the barrel through the connecting shaft, the opening-closing mechanism penetrates through a top plate to be located inside the barrel and be connected with a base plate. According to the barrel plane type suction-preventing rotary excavating drilling bucket, the appearance of the barrel is changed, so that the problem that a direct-barrel type rotary excavating drilling bucket and the pile bottom are large in suction force is solved; a person does not need to drill into the barrel to be additionally provided with a steel plate or a circular steel pipe, so that the barrel plane type suction-preventing rotary excavating drilling bucket is easier to manufacture.
Description
Technical field
The invention belongs to piling machinery technical field, be specifically related to a kind of cylinder plane formula anti-suction rotary drilling digger.
Background technology
It is the advanced stake work construction developed rapidly in the recent period in China that churning driven enters construction, rotary drilling rig and churning driven head either external product or home equipment version and operation principle are similar, but the stratum constructed varies because geographical position is different, the technology constructing concrete requires to have nothing in common with each other again, so only by selecting different drill bit to meet above-mentioned requirement, scientifically select drill bit and reasonably use drill bit, the construction technology of rotary drilling rig can be enriched to a certain extent, widen the construction field of rotary drilling rig.At present, the anti-suction device of the churning driven of the Double bottom on market and single end straight barrel type is to open a breach on base plate, is welded into frame with steel plate or weldering round steel pipe connects drill bit top board and base plate forms passage in drill bit cylinder.This kind of method is implemented to be easier at big churning driven head, but the drill bit of less than 1 meter is little due to drill bit specification, and base areas is little, opens the hole of common anti-suction device without position, causes the drill bit of less than 1 meter cannot configure anti-suction device.
Applicant, by changing drill bit cylinder profile, not only solves little drill bit and cannot configure the problem of anti-suction device, and more save material and less manpower power, yet there are no relevant record.
Summary of the invention
The invention aims to solve the straight barrel type Double bottom of existing small dimension size and single end rotary drilling digger cannot configure anti-suction device and large-scale straight barrel type Double bottom and single end rotary drilling digger configuration troublesome problem of anti-suction device operation, it is proposed that a kind of cylinder plane formula anti-suction rotary drilling digger.
The present invention realizes especially by techniques below scheme:
A kind of cylinder plane formula anti-suction rotary drilling digger, including top plate member, cylinder, bottom deck assembly and open-and-close mechanism, wherein said top plate member is welded in cylinder top, described cylinder body bottom is provided with connecting shaft, the side that cylinder is corresponding with connecting shaft is planar structure, described bottom deck assembly is connected with cylinder by connecting shaft, and described open-and-close mechanism is positioned at inner barrel through top board and is connected with bottom deck assembly.
Described top plate member includes that top board, square set and connecting hole, described square set are welded on top board, and described connecting hole is positioned at the center of square set side, and drill bit is connected with drilling rod by connecting hole.
Described bottom deck assembly includes cutting plate and cutting tooth, and described cutting tooth is welded on cutting plate.
Described open-and-close mechanism includes locating rack, back-moving spring and support bar, and locating rack is welded on square set side, is connected with support bar, and back-moving spring is socketed on support bar and is positioned at above top board.
Top board of the present invention corresponding with cylinder plane while being straight flange.
The invention have the benefit that compared with the drill bit being furnished with common anti-suction device of other forms, not only solve the problem that little drill bit cannot configure anti-suction device, and more save material and less manpower power, common anti-suction device need to make a passage by 2 to 3 block plate weldings or a round steel pipe in drill bit cylinder, and cylinder one side's plane formula anti-suction device churning driven head of the present invention, the problem that absorption affinity at the bottom of straight barrel type rotary drilling digger and stake is big is solved merely with bit contour feature, without separately adding steel plate or round steel pipe in manually creeping into cylinder, the most therefore the present invention one side plane formula anti-suction device churning driven head makes the simplest.
Accompanying drawing explanation
Fig. 1 is the structural representation of plane formula of the present invention anti-suction rotary drilling digger；
Accompanying drawing represents explanation: 1 top plate member, 2 cylinders, 3 bottom deck assemblies, 4 open-and-close mechanisms, 11 top boards, 12 square sets, 13 connecting holes, 21 connecting shafts, 31 cutting plates, 32 cut teeth, 41 locating racks, 42 back-moving springs, 43 support bars.
Detailed description of the invention
Explanation that the present invention will be further explained below in conjunction with the accompanying drawings.
A kind of cylinder plane formula anti-suction rotary drilling digger, including top plate member 1, cylinder 2, bottom deck assembly 3 and open-and-close mechanism 4, wherein top plate member 1 includes top board 11, square set 12 and connecting hole 13, described square set 12 is welded on top board 11, described connecting hole 13 is positioned at the center of square set 12 side, and drill bit is connected with drilling rod by connecting hole 13；Described top plate member 1 is welded in cylinder 2 top, connecting shaft 21 it is provided with bottom cylinder 2, the one side that cylinder 2 is corresponding with connecting shaft 21 is planar structure, and one side straight flange that top board 11 is corresponding with cylinder 2 plane, bottom deck assembly 3 is connected with cylinder 2 by connecting shaft 21, bottom deck assembly 3 includes cutting plate 31 and cutting tooth 32, and described cutting tooth 32 is welded on cutting plate 31；Described open-and-close mechanism 4 is positioned at cylinder 2 inside through top board 11 and is connected with bottom deck assembly 3, open-and-close mechanism 4 includes locating rack 41, back-moving spring 42 and support bar 43, locating rack 41 is welded on square set 12 side, being connected with support bar 43, back-moving spring 42 is socketed on support bar 43 and is positioned at above top board 11.
The upper plate of Double bottom and single subdrilling head is dug in common rotation has a side of hinge to be straight flange, the tubular of wholecircle dig straight barrel type drill bit to be made into a side to be straight flange by this drill bit cylinder one side rotation, this limit be welding hinge while corresponding with the straight flange of upper plate, one side of corresponding top board also makes straight flange, thus as being that the drill bit of wholecircle shape has cut away a small half of from the upper plate position at the top board position of top to lower section originally, the circular stake making churning driven head and get becomes a full communication between the higher and lower levels space, thus produces absorption affinity with at the bottom of stake when preventing from carrying on straight barrel type churning driven head.
