Abstract
The utility model discloses a suspension type digging mechanism which comprises a suspension bracket connected with a loading machine, wherein the suspension bracket is provided with a suspension platform; the suspension platform is rotatablely connected with a main shaft driven by a power device; the main shaft is symmetrically provided with at least two spiral drill bit blades; the lower ends of the spiral drill bit blades are respectively provided with a straight drill cutter blade; the lower end of the main shaft is fixedly provided with an auxiliary cutter head bracket which is provided with an auxiliary cutter head with a sharp end arranged downwards; the suspension bracket is provided with two hinge joint frames which are symmetrically arranged, and a power frame arranged between the two hinge joint frames; the main shaft is connected to the suspension platform by a bearing seat; the power device is a hydraulic motor; and the upper end of the main shaft is connected with the hydraulic motor by power. The suspension type digging mechanism is high in stability, low in abrasion and high in digging accuracy.
Description
Technical field
The utility model relates to a kind of excavation machinery, specifically is a kind of suspension type mechanism of digging pit.
Background technology
When seedling growth or the pile anchoring of herding fence, need to dig pit on the ground earlier.Original way is to adopt manual work to dig pit, and adopting artificial shortcoming of digging pit is that labour intensity is big, and efficiency is low.Existing hole digger adopts tractor back suspended, and the mechanism that is about to dig pit is suspended on the tractor rear portion, and the mechanism of digging pit comprises hanger bracket; Be rotatably connected to the main shaft that drives by power set on the hanger bracket; Spiral helicine drilling blade is housed on the main shaft, and the width of drilling blade is gradually little from top to bottom, adopts this hole digger when digging pit, to have disadvantage: quick abrasion in this spiral helicine drilling blade working process; Poor stability, thus cause use cost high; And the operator is difficult to observe the degree of depth of digging pit and the state of digging pit, and is not easy to operate.
The utility model content
The technical problem that the utility model will solve provides that a kind of stability is high, the little suspension type of wearing and tearing is digged pit mechanism.
For solving the problems of the technologies described above; The suspension type that the is provided mechanism of digging pit comprises the hanger bracket that can be connected with loading machine, and its design feature is: hanger bracket is provided with suspension platform, is rotatably connected to the main shaft that is driven by power set on the suspension platform; Symmetrically arranged at least two helical form bit blades are housed on the main shaft; The lower end of each bit blades is equipped with straight drill blade respectively, and the lower end of main shaft is fixed with auxilliary cutter head support, on the auxilliary cutter head support tip auxilliary cutter head down is housed.
After adopting said structure, when digging pit, start power set and drive main shaft and rotate, punch on the ground through auxilliary cutter head earlier, carry out reaming through straight drill blade again, the direct wearing and tearing of drill blade are diminished; Symmetrically arranged helical form bit blades can make under the steady more ground auger of this mechanism; Soil after the drilling be sent on the ground along with the rotation of bit blades and be distributed under the action of centrifugal force hole around; Thereby this mechanism stable property is high, wearing and tearing are little, and the accuracy height of digging pit.
Improvement as the utility model; The symmetrically arranged two body cradles power rack middle with being positioned at two body cradles is housed on the said hanger bracket; Body cradle and power rack are hinged on the angle adjustment frame of loading machine front end; Can this mechanism be installed in the front portion of loading machine, be convenient to the operator and observe state and the drilling situation of digging pit, help safety operation.
Said main shaft is connected on the suspension platform through bearing block, and said power set are hydraulic motor, and the upper end of main shaft is connected with hydraulic motor power.
In sum, the utlity model has the advantage that stability is high, wearing and tearing are little and the accuracy of digging pit is high.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model;
Fig. 2 be among Fig. 1 A to sketch map.
Embodiment
The suspension type as shown in Figure 1 mechanism of digging pit; It comprises frame 1, comprises the hanger bracket 1 that can be connected with power car, and hanger bracket 1 is provided with suspension platform 2; Be rotatably connected to the main shaft 3 that drives by power set on the suspension platform 2; Main shaft 3 is connected on the suspension platform 2 through bearing block 9, and power set are hydraulic motor 8, and the upper end of main shaft 3 is connected with hydraulic motor 8 power.Symmetrically arranged at least two helical form bit blades 4 are housed on the main shaft 3; Two helical form bit blades 4 have been shown among Fig. 1, and above-mentioned symmetry is meant center, the axle center symmetry with main shaft 3, and the lower end of each bit blades 4 is equipped with straight drill blade 5 respectively; Drill blade 5 and main shaft 3 vertical settings and when main shaft 3 during perpendicular to ground; Drill blade 5 is slanted angle with ground, and the lower end of main shaft 3 is fixed with auxilliary cutter head support 6, on the auxilliary cutter head support 6 tip auxilliary cutter head 7 down is housed; The leading section setting triangular in shape of auxilliary cutter head 7, vertex of a triangle are the tip of auxilliary cutter head 7.
As shown in Figure 2, symmetrically arranged two body cradles 11 are housed on the hanger bracket 1 adapt and can link together through hinge with power rack 12, two body cradles 11 that are positioned at two body cradles, 11 centres and the position and the link position on the loading machine of power rack 12.
