Abstract
The unity model relates to a piercer, including a hand grip, a drill pipe and screw augers; one end of the drill pipe is set with the hand grip, and the other end with one or man circle of screw augers with curved cutting surface. The unity model is characterized that: the radial curved cutting surface near the surfaced part of the screw auger of the handle is connected with the mobile board; the screw augers towards the hand grip are set with bead; the second part of the helicoid towards the screw auger of the hand grip are set with salient blocks, between salient blocks notches are set; salient block arrange to the tangent from the outer curved cutting surface at angle alpha, incisions of wave-like cutting edge are set on the second part of the outer curved cutting surface of the contralateral of screw auger with the arrangement of elliptical salient blocks. The advantages of the unity model are the enhancement of reliability and work efficiency.
Description
Technical field
The utility model relates to a kind of drill, is used in the soil and holes, and belongs to the boring bar tool technical field.
Background technology
Be used for the drill of making holes in soil at present, it has drilling rod, an end band rocking arm of drilling rod, and be equipped with an augers of being with cutting edge at least at the other end, cutting edge has a circle spiral at least.Its shortcoming is that drilling efficiency is not high enough, and device reliability is good inadequately.
Summary of the invention
The purpose of this utility model is a kind of drill that improves reliability and operating efficiency of invention.
For realizing above purpose, the technical solution of the utility model provides a kind of drill, comprise handle, drilling rod, augers, one end of drilling rod is provided with handle, the other end of drilling rod is provided with at least one circle augers in band cutting face, it is characterized in that, the radial cut bevel at the surperficial position of the augers of close handle connects portable plate, on a part of augers of handle, be provided with crimping, second portion helicoid towards the augers of handle is provided with projection, be provided with recess between the projection, projection is the α angle from the outer cutting face of augers to its tangent line to be arranged, and is provided with the otch of sharp keen undaform cutting edge outside the second portion of the augers of the offside of arranging oval projection on the cutting face.
The utility model adopt portable plate can make soil layer around the drill bit to the drill bit central mobile, earth can not be deposited on the outer cutting face of drill bit, so the earth that downcuts can not fall back in the hole of formation and go, make earth rise to the surface and become easy, second portion helicoid towards the augers of handle is provided with projection, be provided with recess between the projection, outside the second portion of the augers of the offside of arranging oval projection, be provided with the otch of sharp keen undaform cutting edge on the cutting face, make that to pierce earth easier, increase work efficiency.
The utility model has the advantages that and improve reliability and operating efficiency.
Description of drawings
Fig. 1 is a kind of drill structural representation;
Fig. 2 is the augers structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As Fig. 1, shown in 2, be a kind of drill structural representation, described a kind of drill, comprise handle 1, drilling rod 2, augers 3, one end of drilling rod 2 is installed handle 1, at least one circle augers 3 in other end mounting strap cutting face of drilling rod 2, augers 3 flat surperficial positions 5 near handle 1 connect laminal portable plate 6, portable plate 6 rotating sides 7 are fixed on the radial cut bevel 8 near the flat position 5 of the augers 3 of handle 1, the sheeting 6 of exceeding is rotated to handle 1 direction, thin plate 6 is made band projection 9, on a part of augers 3 of handle 1, crimping 10 is being arranged, on the second portion helicoid of the augers 3 of handle 1, make oval projection 11, form recess 12 between the projection; Oval projection 11 is 10 ° of angles from the outer cutting face 13 of augers 3 to its tangent line to be arranged, and on the cutting face otch 4 is arranged outside the second portion of the augers 3 of the offside of arranging oval projection 11, forms sharp keen undaform cutting edge.
During work, drill is placed on desired area on the soil with certain pressure, behind augers 3 insertion earth, drill is by drilling rod 2 rotations of handle 1 around oneself, during the drill rotation, in the cutting face 4 incision soil of augers 3, at this moment, the tooth of the second portion helicoid of sharp keen augers 3 makes cuts soil layer easily, and by oval projection 11 and recess 12, soil is from edge trend central authorities, that is move from the cutting face to drilling rod 2, thereby avoid being deposited on the cutting face, also avoid earth to fall back in the hole of having bored, can rise to ground surface to it easily.
