Including a joint arm, two joint arms, three joint arms, four joint arms, fuselage, a joint arm, two joint arms, three joint arms, four joint arms pass sequentially through rotating shaft
Connection, the shaft parallel between a fuselage and joint arm, a joint arm and two joint arms, three joint arms and four joint arms is in horizontal plane, two joint arms
Rotating shaft between three joint arms is vertical with the rotating shaft between a joint arm and two joint arms.
As optimization, the aid be bucket, hay mover, trimmer, churning driven, pawl tool, snow plough, stone crusher,
Positive backhoe, fork dress device, gardens corrector, lumbering device, shifting tree device, railway change pillow device, plough, plane road device, quartering hammer, hydraulic tongs
In any one.
As optimization, the rotating shaft between a fuselage and joint arm, a joint arm and two joint arms, three joint arms and four joint arms, phase
To the horizontal horizontal line that the operator in fuselage operating room is face；Rotating shaft and fuselage longitudinal cross-section between two joint arms and three joint arms
It is parallel.
As optimization, the length of the three joint arms is more than fuselage width.
As optimization, a fuselage and joint arm, a joint arm and two joint arms, two joint arms and three joint arms, three joint arms and four sections
Hydraulic drive mechanism is both provided between arm, four joint arms and aid.
As optimization, the hydraulic drive mechanism includes hydraulic cylinder.
As optimization, the both ends of the hydraulic cylinder between two joint arms and three joint arms respectively by rotating shaft connect two joint arms,
The side of three joint arms.
The effect provided in the content of the invention is only the effect of embodiment, rather than whole effects that invention is all, above-mentioned
Technical scheme has the following advantages that or beneficial effect：
1. by setting the rotating shaft between two joint arms and three joint arms vertical with the rotating shaft between a joint arm and two joint arms, swing arm
Operating angle can carry out Level tune, have the bigger free degree, and the narrow locations such as roadside, gorge, corner can be carried out
Operation.
2. because swing arm employs four joint arms, during equal tonnage, excavating depth is deeper, loading height is higher.
Brief description of the drawings
Fig. 1 is the front view of an embodiment of the present invention.
Embodiment
In order to the technical characterstic of clear explanation this programme, below by embodiment, and its accompanying drawing is combined, to this
Invention is described in detail.Following disclosure provides many different embodiments or example is used for realizing the different knots of the present invention
Structure.In order to simplify disclosure of the invention, hereinafter the part and setting of specific examples are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relation between various embodiments are discussed and/or set.It should be noted that part illustrated in the accompanying drawings is not necessarily to scale
Draw.Present invention omits the description to known assemblies and treatment technology and process to avoid being unnecessarily limiting the present invention.
Fig. 1 is a kind of embodiment of the present invention, as illustrated, a kind of four joint arm excavators, including it is fuselage 1, swing arm 2, auxiliary
Assistant engineer's tool 3, swing arm 2 is installed on the fuselage 1, and aid 3 is arranged on the end of swing arm 2, and swing arm 2 saves including a joint arm 21, two
Arm 22, three joint arms 23, four joint arms 24, fuselage 1, a joint arm 21, two joint arms 22, three joint arms 23, four joint arms 24 pass sequentially through rotating shaft
Connection, the shaft parallel between the joint arm 21 of fuselage 1 and one, a joint arm 21 and two joint arms 22, the joint arm 24 of three joint arms 23 and four is in water
Plane, the rotating shaft between two joint arms 22 and three joint arms 23 are vertical with the rotating shaft between a joint arm 21 and two joint arms 22.
The aid 3 is bucket, hay mover, trimmer, churning driven, pawl tool, snow plough, stone crusher, positive backhoe, fork
Dress device, gardens corrector, lumbering device, shifting tree device, railway change any in pillow device, plough, plane road device, quartering hammer, hydraulic tongs
It is a kind of.
Rotating shaft between the joint arm 21 of fuselage 1 and one, a joint arm 21 and two joint arms 22, the joint arm 24 of three joint arms 23 and four,
With respect to the horizontal horizontal line that the operator in the operating room of fuselage 1 is face；Rotating shaft and fuselage 1 between two joint arms 22 and three joint arms 23
Longitudinal cross-section is parallel.
The length of the three joint arms 23 is more than the width of fuselage 1.
The joint arm 21 of fuselage 1 and one, a joint arm 21 and two joint arms 22, two joint arms 22 and three joint arms 23, three joint arms 23 with
Hydraulic drive mechanism 3 is both provided between four joint arms 24, four joint arms 24 and aid 3.
The hydraulic drive mechanism 4 includes hydraulic cylinder 41.
The both ends of hydraulic cylinder 41 between two joint arm 22 and three joint arms 23 connect two joint arms 22, three by rotating shaft respectively
The side of joint arm 23.
By setting the rotating shaft between rotating shaft and a joint arm 21 and two joint arms 22 between two joint arms 22 and three joint arms 23 to hang down
Directly, the operating angle of swing arm 2 can carry out level angle regulation, such as：The positions such as roadside, gorge, corner are excavated
During work, aid 3 is bucket, ensures that two joint arms 22 and three joint arms are horizontal, and because the length of three joint arms 23 is more than machine
Bucket can be adjusted to the side of fuselage 1, satisfied the need so as to realize by the width of body 1, the rotating shaft adjusted between two joint arms 22 and three joint arms 23
The excacation of the positions such as side, gorge, corner.
Because swing arm 2 employs four joint arms, during equal tonnage, excavating depth is deeper, loading height is higher.
Although above-mentioned the embodiment of invention is described with reference to accompanying drawing, not to the scope of the present invention
Limitation, on the basis of technical scheme, those skilled in the art need not pay creative work and can make
Various modifications or deformation still within protection scope of the present invention.
