Abstract
The utility model relates to an unearthed drilled bit structure for a hole-digging machine. The unearthed drilled bit structure comprises a screw rod, wherein a joint is arranged at the upper end of the screw rod, and a drill bit which extends downwards is fixed at the lower end of the screw rod; double-threaded screws are symmetrically fixed on the screw rods; a tool apron is fixed at the lower end of each screw; a blade is connected to the tool apron; and the blade is fixed on the tool apron through a bolt connecting piece. By adoption of a double-threaded screw unearthed mode, the periphery of the drill bit can be kept balanced, vibration and eccentric effects are avoided, the operation is stable in the process of cutting the soil and taking out the soil by screwing through the blade, and the efficiency is higher. Moreover, by adoption of a detachable structure, the blade can be detached, repaired or replaced.
Description
Technical field
The utility model relates to agriculture and forestry machinery, specifically a kind of unearthed drill bit structure that digs cave machine.
Background technology
For many years, China governments at all levels pay much attention to " afforestation work ".In all parts of the country according to local weather conditions, at spring and autumn, carrying out a large amount of tree planting work, for the green hill of China is evergreen, the earth is green for a long time, check winds and fix drifting sand, cities and towns are beautified, environmental protection and the mankind's health has played huge effect.
In today of all trades and professions science and technology high speed development, in the plane cave work of digging pit of planting trees in vast mountain region, also still adopting the mode of production of " pick " pit digging that has continued centuries.This pit digging mode, not only production efficiency is low, labour intensity is high, physical demands is large, plane cave is of poor quality, producing cost is surprising, and particularly in epoch of society " difficulty of asking someone, recruitment famine ", the government organs and the commercial company that are engaged in afforestation " are suffered untold misery ", seriously affected carrying out smoothly of afforestation work.
Although the Some Enterprises of developed country and China has been produced the hole digger of machine-carried type, due to the mountain topography complexity of afforestation, soil property, containing husky, different containing stone, is difficult to enter fieldwork, therefore fails so far extensively to be utilized.
The portable ground auger occurring on market, generally adopts single coil configuration, and the effect of being unearthed is poor, and drill bit is difficult to keep balance, at rotating speed, can produce because lay particular stress on vibration and eccentricity effect when high; In addition, its blade is non-dismountable, after breaks down, can only change whole drill bit, has increased use cost.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of unearthed drill bit structure that digs cave machine, and this structure, for the portable plane cave machine of planting trees, can make to dig cave machine and operate steadily, and unearthed efficiency is high.
According to the technical solution of the utility model: a kind of unearthed drill bit structure that digs cave machine, comprise screw rod, the upper end of described screw rod is provided with connector, its lower end is fixed with the drill bit extending downwards, on described screw rod, be symmetrically fixed with twin-feed spiral, the lower end of each described spiral is fixed with tool rest, on described tool rest, is connected with blade.
Described screw rod adopts steel pipe to make, and its upper and lower two ends are welded with respectively plug, and described connector and described drill bit are welded on respectively on described plug.
Described blade is fixed on described tool rest by bolt connection piece.
Described blade is connected with described tool rest by three cover bolt connection pieces.
On described tool rest, be provided with the step of the described blade in location.
Angle between described blade and described drill bit is 85 °, and the angle between described blade and its direction of advance is 15 °.
Technique effect of the present utility model is: the utility model adopts the twin-feed spiral mode of being unearthed, and can make drill bit circumference keep balance, can not produce vibration and eccentricity effect, and more steady when blade incision earth and outward turning earth, and efficiency is higher; Blade adopts Demountable, detachably repairs or changes; Blade is taked three-point fix, is conducive to quick location and the incision of cutter.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view Amplified image in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
In Fig. 1, Fig. 2, comprise drill bit 33, blade 34, tool rest 35, screw 36, packing ring 37, nut 38, plug 39, spiral 40, screw rod 41, connector 42 etc.
As shown in Figure 1, the utility model is a kind of unearthed drill bit structure that digs cave machine, comprises screw rod 41.Screw rod 41 adopts steel pipe to make, and its upper and lower two ends are welded with respectively plug 39.
The upper end of screw rod 41 is provided with connector 42, and its lower end is fixed with the drill bit 33 extending downwards, and connector 42 is welded on respectively on plug 39 with drill bit 33.Connector 42 is for being connected to the utility model on the power set of plane cave machine.
On screw rod 41, be symmetrically fixed with twin-feed spiral 40, the diameter of spiral 40 can be divided into all sizes such as Φ 200, Φ 250, Φ 300, Φ 400 and Φ 500, can arbitrarily change.The lower end of each spiral 40 is fixed with tool rest 35, is connected with blade 34 on tool rest 35.Blade 34 adopts high-speed alloy Steel material through special processing processing, can drilling sandstone class earth, and durable in use.Angle between blade 34 and drill bit 33 is 85 °, and as shown in Figure 2, the angle between blade 34 and its direction of advance is 15 °.
Blade 34 is fixed on tool rest 35 by bolt connection piece screw 36, packing ring 37 and nut 38.Blade 34 is preferably connected with tool rest 35 by three cover bolt connection pieces.
As shown in Figure 2, on tool rest 35, be also provided with the step of positioning blade 34.
The utility model adopts the unearthed mode of twin-feed spiral, the advantage of twin-feed spiral 40 is to make drill bit circumference keep balance, at rotating speed, can not lay particular stress on and produce vibration and eccentricity effect because of indivedual points when high, and more steady when blade incision earth and outward turning earth, and efficiency is higher; Two blades 34 adopt Demountable, once the impaired detachable reparation of blade or replacing; Blade 34 is taked three-point fix, and the point of a knife three-point fix circular motion of drawing a picture, is conducive to quick location and the incision of cutter.
