Abstract
The utility model relates to a hacking drill structure for a hole digging machine. The hacking drill structure comprises a cutter bar; a connecting head is arranged at the upper end of the cutter bar; a cutter head assembly is connected with the lower end of the cutter bar; the cutter head assembly comprises a cutter base; a drill extending downward is fixed at the lower part of the cutter base; three blades extending in the radical direction are uniformly distributed on the side wall of the cutter base. According to the utility model, the cutter head of three fixed blades assembly is adopted, so that the function of hacking without leaving a hole is realized; not only are soil and stone hacked, but also the hole model is in good condition; the cutter head adopts a dismountable structure, so that a blade can be dismounted to repair or replace once the blade is damaged; using cost is reduced.
Description
Technical field
The utility model relates to agriculture and forestry machinery, specifically a kind of hack drill bit structure that digs cave machine.
Background technology
For many years, governments at all levels of China pay much attention to " afforestation work ".In all parts of the country according to local weather conditions, carrying out a large amount of tree planting work at spring and autumn, 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 earth digging out is brought to grass.This ground auger can not can not realized and cheat hack effect; 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 hack drill bit structure that digs cave machine, and this structure is for the portable plane cave machine of planting trees, and can make to dig cave machine and can not realize and cheat soil-crushing function.
According to the technical solution of the utility model: a kind of hack drill bit structure that digs cave machine, comprise knife bar, the upper end of described knife bar is provided with connector, and its lower end is connected with cutter head combination; Described cutter head combination comprises that tool rest, the below of described tool rest are fixed with the drill bit extending downwards, is evenly equipped with three blades that radially extend on the sidewall of described tool rest.
Described knife bar adopts steel pipe to make, and its upper and lower two ends are welded with respectively plug, and described connector is welded on the described plug of described knife bar upper end.
The below of the described plug of described knife bar lower end is welded with square shaft and stretches, and the top of described tool rest has with described square shaft stretches the square hole matching, and described tool rest is enclosed within described square shaft by described square hole and stretches, and is connected by lower bearing pin.
Angle between described blade and described drill bit is 82 °, and the angle between described blade and its direction of advance is 10 °.
Technique effect of the present utility model is: the utility model adopts three fixed blade combined tool bits, can not realize and cheat soil-crushing function, can smash native stone to pieces and can keep again cave type intact; Cutter head combination adopts Demountable, once the impaired detachable reparation of blade or replacing have reduced use cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the structure enlarged diagram of the cutter head combination in the utility model.
Fig. 4 is the vertical view of Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
In Fig. 1～Fig. 4, comprise that drill bit 43, blade 44, tool rest 45, square shaft stretch 46, lower bearing pin 47, plug 48, knife bar 49, upper pin 50, connector 51, square hole 52 etc.
As shown in Figure 1 and Figure 2, the utility model is a kind of hack drill bit structure that digs cave machine, comprises knife bar 49.Knife bar 49 adopts steel pipe to make, and its upper and lower two ends are welded with respectively plug 48.
The upper end of knife bar 49 is provided with connector 51, and connector 51 is welded on the plug 48 of knife bar 49 upper ends.On connector 51, have pin-and-hole, by upper pin 50, the utility model is connected on the power set of plane cave machine.
The below of the plug 48 of knife bar 49 lower ends is welded with square shaft and stretches 46, and square shaft is stretched on 46 and is connected with cutter head combination by lower bearing pin 47.The diameter of cutter head combination can be divided into all sizes such as Φ 200, Φ 250, Φ 300, Φ 400 and Φ 500, can arbitrarily change.
Cutter head combination comprises that tool rest 45, the below of tool rest 45 are fixed with the drill bit 43 extending downwards.The top of tool rest 45 has with square shaft stretches 46 square holes that match 52, and tool rest 45 is enclosed within square shaft by square hole 52 and stretches on 46, and is connected by lower bearing pin 47.
As shown in Figure 3, Figure 4, on the sidewall of tool rest 45, be evenly equipped with three blades 44 that radially extend, form three fixed combination formula cutter heads.Blade 44 adopts high-speed alloy Steel material through special processing processing, can lead plug sandstone class earth, and durable in use.
As shown in Figure 4, the angle between blade 44 and drill bit 43 is 82 °, and the angle between blade 44 and its direction of advance is 10 °.
The utility model adopts three fixed blade combined tool bits, can not realize and cheat soil-crushing function, can smash native stone to pieces and can keep again cave type intact; Cutter head combination adopts Demountable, once the impaired detachable reparation of blade or replacing have reduced use cost.
