The said mechanism of digging pit comprises the hanger bracket that is connected with the lifting swing arm with above-mentioned rocking arm; Be rotatably connected to the main shaft that drives by power set on the hanger bracket; 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.
The symmetrically arranged two body cradles power rack middle with being positioned at two body cradles is housed on the said hanger bracket, and said lifting swing arm and two body cradles are hinged, and the end of said rocking arm is hinged through connecting rod and power rack.
Said main shaft is connected on the hanger bracket through bearing support, and said power set are hydraulic motor, and the upper end of main shaft is connected with hydraulic motor power.
Balance weight iron is equipped with at the rear portion of said vehicle frame.
After adopting said structure, when digging pit, drive the mechanism's level of digging pit through oscillating oil cylinder driving front rack and swing; Thereby confirm horizontal level, through the dig pit height of mechanism of lift cylinder adjustment, through the dig pit verticality of mechanism of angle adjustment oil cylinder adjustment; Thereby adjusted the three-dimensional position of the mechanism of digging pit exactly, and adjusted through above-mentioned oil cylinder, operation is very nimble; Operator's labour intensity reduces greatly, and efficiency is high.
In sum, the utlity model has the advantage that the angle of digging pit is prone to adjustment, flexible operation.
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 is the structural representation of mechanism of digging pit;
Fig. 3 be among Fig. 2 A to sketch map.
The specific embodiment
Trench excavator as shown in Figure 1; It comprises vehicle frame 1, is installed in the driver's cabin 19 on the vehicle frame 1 and is installed in the walking mechanism on the vehicle frame; Walking mechanism is formed by being contained in engine 20 on the vehicle frame 1 and the road wheel 21 that is connected with engine 20 power; Engine 20 is installed in the rear portion of vehicle frame 1, and the balance weight iron 17 that is positioned at engine 20 belows also is equipped with at the rear portion of vehicle frame 1.The front end of vehicle frame 1 is hinged with front rack 2 and drives the oscillating oil cylinder 3 of front rack 2 horizontal huntings, and oscillating oil cylinder 3 is symmetrical set two altogether, when two oscillating oil cylinders 3 move simultaneously; But front rack 2 levels swing; Be hinged with the hoist cylinder 5 that promotes swing arm 4 and drive the up-down of lifting swing arm 4 front ends on the front rack 2, the rear portion hinge of hoist cylinder 5 is contained on the front rack 2, its piston rod hinge is contained in the middle front part that promotes swing arm 4, and the front end of lifting swing arm 4 is hinged with the mechanism of digging pit; Angle adjustment oil cylinder 6 also is housed on the front rack 2; Promote on the swing arm 4 and be hinged with rocking arm 7, an end of the piston rod of angle adjustment oil cylinder 6 and rocking arm 7 is hinged, the other end of rocking arm 7 is hinged, as shown in figures 1 and 3 with the mechanism of digging pit; Promote swing arm 4 front ends and have two support arms that laterally arrange; Supporting base 18 is equipped with at two support arms middle part, is hinged with connecting rod 22 on the supporting base 18, and the middle part hinge of connecting rod 22 is contained on the supporting base 18.
Like Fig. 1, Fig. 2 and shown in Figure 3; The above-mentioned mechanism of digging pit comprises the hanger bracket 8 that is connected with lifting swing arm 4 with above-mentioned rocking arm 7; Following structure is adopted in this connection: symmetrically arranged two body cradles 14 and the power rack 15 that is positioned at two body cradles, 14 centres are housed on the hanger bracket 8; It is hinged with two body cradles 14 to promote swing arm 4, and the end of rocking arm 7 is hinged through connecting rod 22 and power rack 15, and promptly 7 hinged, the other end of an end of connecting rod and rocking arm and power rack 15 cut with scissors and adorn.Be rotatably connected to the main shaft 9 that is driven by power set on the hanger bracket 8, main shaft 9 is connected on the hanger bracket 8 through bearing support, and power set are hydraulic motor 16, and the upper end of main shaft 9 is connected with hydraulic motor 16 power.Symmetrically arranged at least two helical form bit blades 10 are housed on the main shaft 9; Two helical form bit blades 10 have been shown among Fig. 2, and above-mentioned symmetry is meant center, the axle center symmetry with main shaft 9, and the lower end of each bit blades 10 is equipped with straight drill blade 11 respectively; Drill blade 11 and main shaft 9 vertical settings and when main shaft 9 during perpendicular to ground; Drill blade 11 is slanted angle with ground, and the lower end of main shaft 9 is fixed with auxilliary cutter head support 12, on the auxilliary cutter head support 12 tip auxilliary cutter head 13 down is housed; The leading section setting triangular in shape of auxilliary cutter head 13, vertex of a triangle are the tip of auxilliary cutter head 13.
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 the mechanism stability of originally digging pit is high, wearing and tearing are little, and the degree of accuracy height of digging pit.
