Abstract
The utility model relates to a kind of removable novel forest land hole digger drill head, comprise drill body, the top bolt of described drill body is connected with drilling rod, on the sidewall of described drilling rod, be surrounded with helical blade, in the two opposite side walls of described drill body top, be respectively arranged with blade, the angle of described two blades is 180 °.Described blade is tilted to lower setting, and the blade of blade is towards the tip place of drill body, and the angle of slope of described blade is 7 ~ 15 °.Described helical blade was around drilling rod 2 ~ 3 weeks.This drill bit not only can be changed and use rear impaired drill bit, can also in the process of boring cave, cut off tree root or grass roots, is suitable for forest land weedtree, weeds root occasion how.
Description
Technical field
The utility model relates to a kind of removable novel forest land hole digger drill head.
Background technology
In the time that forest land weedtree, weeds root geographical environment how are bored to cave operation, often because the complexity of geographical environment causes drill bit well damage, but but easy damaged not of helical blade on drilling rod, because the damage of drill bit, have to change whole product, caused huge waste, meanwhile, tree root, grass roots etc. has also affected the efficiency of digging cave operation.
Utility model content
The problem that the utility model exists for above-mentioned prior art is made improvement, be that technical problem to be solved in the utility model is to provide a kind of removable novel forest land hole digger drill head, not only can change and use rear impaired drill bit, can also in the process of boring cave, cut off tree root or grass roots, and due to the balanced action of double blade, greatly reduce the vibrations of machinery in operating process, be suitable for forest land weedtree, weeds root occasion how.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of removable novel forest land hole digger drill head, comprise drill body, the top bolt of described drill body is connected with drilling rod, on the sidewall of described drilling rod, be surrounded with helical blade, in the two opposite side walls of described drill body top, be respectively arranged with blade, the angle of described two blades is 180 °.
Further, described blade is tilted to lower setting, and the blade of blade is towards the tip place of drill body, and the angle of slope of described blade is 7 ~ 15 °.
Further, for loosening the soil in minimizing cave is output and reduce drill bit weight; Described helical blade was around drilling rod 2 ~ 3 weeks.
Compared with prior art, the utlity model has following beneficial effect: this drill bit not only can be changed and use rear impaired drill bit, can also in the process of boring cave, cut off tree root or grass roots, and due to the balanced action of double blade, the vibrations of machinery in operating process are greatly reduced, be suitable for forest land weedtree, weeds root occasion how, use simple, cost-saving.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Brief description of the drawings
Fig. 1 is the organigram of the utility model embodiment.
In figure: 1-drill body, 11-blade, 2-drilling rod, 21-helical blade.
Detailed description of the invention
Embodiment: as shown in Figure 1, a kind of removable novel forest land hole digger drill head, comprise drill body 1, the top bolt of described drill body 1 is connected with drilling rod 2, on the sidewall of described drilling rod 2, be surrounded with helical blade 21, in described drill body 1 top two opposite side walls, be respectively arranged with blade 11, the angle of described two blades 11 is 180 °.
In the present embodiment, described blade 11 is tilted to lower setting, be that the blade of blade 11 is towards the tip place of drill body, the angle of slope of described blade 11 is 7 ~ 15 °, there is the blade that cuts off tree root or grass roots, greatly improved the durability of drill bit, simultaneously the setting of two-phase blade 11, the balance of the drill bit providing, reduces the vibrations of digging cave.
In the present embodiment, be output and reduce drill bit weight for reducing loosening the soil in cave; Described helical blade 21 was around drilling rod 2 ~ 3 weeks.
In the present embodiment, it is manganese steel that blade adopts material, and adopts one-shot forming, can improve durability.
In the present embodiment, this drill bit also can be used for plant pit and mixes fertilizer, reaches a multiplex object.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
