Abstract
The invention discloses a spirally bottom-expanding integrated drill bit. The drill bit comprises a drill stem, a left bottom-expanding arm and a right bottom-expanding arm, wherein the bottom of the drill stem is fixedly connected with an outer sleeve; an inner sleeve is glidingly arranged in the outer sleeve in a matching way; an arm-protecting plate is fixedly arranged outside the outer sleeve; a soil-accommodating disc is fixedly arranged at the bottom end of the inner sleeve; the upper ends of the left bottom-expanding arm and the right bottom-expanding arm are respectively hinged to the two sides of the arm-protecting plate; and the lower ends of the left bottom-expanding arm and the right bottom-expanding arm are respectively hinged to the soil-accommodating disc through connecting rods. The drill bit is simple and reliable in structure and convenient to operate. During bottom-expanding operation, soil is collected through the soil-accommodating disc, and when the drill bit is lifted out of a pile, the soil can be taken out together, so that the time and the labor are saved, and the operation efficiency of the drill bit is greatly improved. In addition, the vertical compression-resistant performance of the pile can be improved, and the drill bit has a wider popularization and application space in the field of buildings.
Description
Technical field
The present invention relates to the bottom expanding drill field, specifically is that a kind of spiral expands end integral type drill bit.
Background technology
Bottom expanding drill is the drill bit of construction expanded bore pile in rotary drilling.Generally form by expanding the end wing, pressure frame, connecting rod, base and bearing pin.Expanding the end wing has both wings, three wings or four wings, and the expansion end wing is opened gradually, and the cutting hole wall expands the end.
But, the most complex structure of existing bottom expanding drill, relatively heavier, cost is higher.When expanding end operation, can below the face of land, form a deep hole, be also referred to as stake; And the earth that expands end formation can be deposited in the stake; Need drill bit be proposed, again the earth in the stake collected on the face of land through manual work or plant equipment, so just have influence on the operating efficiency of drill bit.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate spiral and expand end integral type drill bit, when expanding end operation, through soil holding disk earth is collected, when drill bit proposed in stake, earth can be taken out of in the lump, and was time saving and energy saving.
Technical scheme of the present invention is following:
A kind of spiral expands end integral type drill bit, includes drilling rod, has helical blade on the outer wall of said drilling rod; It is characterized in that: the bottom of said drilling rod is fixedly connected with outer sleeve, the upper end closed of said outer sleeve, and the lower end of outer sleeve is uncovered; Through the inner sleeve that has been slidingly installed, stretch out from the lower end of outer sleeve is uncovered the bottom of said inner sleeve, and the upper end of inner sleeve is uncovered in the outer sleeve; The lower end closed of inner sleeve; Be provided with spring in the inner sleeve, an end of said spring leans the upper end inner bottom surface of sleeve outside, and the other end roof pressure of spring is inner bottom surface in the lower end of inner sleeve; The external stability of said outer sleeve has the armlet plate; The bottom of said inner sleeve is fixed with soil holding disk; Include arm at the bottom of the left and right expansion; The upper end of arm is hinged on the both sides of armlet plate respectively at the bottom of the said left and right expansion, passes through rod hinge connection at the bottom of the left and right expansion between the lower end of arm and the soil holding disk respectively, is fixed with a plurality of alloy cutter heads at the bottom of the left and right expansion on the arm respectively.
Described spiral expands end integral type drill bit, and it is characterized in that: there is mount pad the upper end of said drilling rod.
Described spiral expands end integral type drill bit, and it is characterized in that: the bottom of said soil holding disk is fixedly welded with sharp type piece.
Beneficial effect of the present invention:
The present invention is simple in structure, reliable, and is easy to operate, when expanding end operation, through soil holding disk earth collected, and when drill bit proposed in stake, earth can be taken out of in the lump, and was time saving and energy saving, improved the operating efficiency of drill bit greatly; In addition, the present invention can improve the vertical compression performance of stake, at building field bigger promotion and application space is arranged.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Referring to Fig. 1, a kind of spiral expands end integral type drill bit, includes drilling rod 1; Have helical blade 2 on the outer wall of drilling rod 1, the bottom of drilling rod 1 is fixedly connected with outer sleeve 3, the upper end closed of outer sleeve 3; The lower end of outer sleeve 3 is uncovered, and through the inner sleeve 4 that has been slidingly installed, stretch out from the lower end of outer sleeve 3 is uncovered the bottom of inner sleeve 4 in the outer sleeve 3; And the upper end of inner sleeve 4 is uncovered, and the lower end closed of inner sleeve 4 is provided with spring 5 in the inner sleeve 4; One end of spring 5 leans the upper end inner bottom surface of sleeve 3 outside, and the other end roof pressure of spring 5 is inner bottom surface in the lower end of inner sleeve 4; The external stability of outer sleeve 3 is welded with armlet plate 6; The bottom of inner sleeve 4 is fixedly welded with soil holding disk 7; Include arm 8,9 at the bottom of the left and right expansion; The upper end of arm 8,9 is hinged on the both sides of armlet plate 6 respectively at the bottom of the left and right expansion, and is hinged through connecting rod 10 respectively between the lower end of arm 8,9 and the soil holding disk 7 at the bottom of the left and right expansion, is fixed with a plurality of alloy cutter heads 11 at the bottom of the left and right expansion on the arm 8,9 respectively.
There is mount pad 12 upper end of drilling rod; The bottom of soil holding disk is fixedly welded with sharp type piece 13, plays the effect of stablizing whole drill bit and the effect of drill guide stake.
At first on the face of land, get out a hole through common augers, through mount pad 12 that whole drill bit is rack-mount then, the upper end of motor on the support and drilling rod 1 is in transmission connection; Arm 8,9 and soil holding disk 7 rotate together at the bottom of driven by motor drilling rod 1, inner and outer sleeves 5,4, armlet plate 6, the left and right expansion; Under the drive of the hoisting mechanism on the support, drilling rod 1 moves down along the inwall of hole gradually, when sharp type piece 13 arrives the inner bottom surface of hole; Drilling rod 1 is slightly pressurizeed; This moment, inner sleeve 4 moved on outer sleeve 3 inwalls, spring 5 compressions, and arm 8,9 opens in hole gradually at the bottom of the left and right expansion; A plurality of alloy cutter heads 11 at the bottom of the left and right expansion on the arm 8,9 are rotating and are expanding end operation, and the earth that expands end operation generation can fall in the soil holding disk 7 of inner sleeve 4 bottoms automatically; After expanding end operation completion, the hoisting mechanism on the support is mentioned drilling rod 1 gradually, under action of gravity; Inner sleeve 4 moves down along outer sleeve 3 inwalls, and spring 5 is upheld, and arm 8,9 shrinks in hole gradually at the bottom of the left and right expansion; Finally along with drilling rod 1 proposes from hole; And the earth that expands end operation generation is taken out of with soil holding disk 7 in the lump, so far, expands end operation and finishes.
