Abstract
The invention relates to a harvester mechanical arm. The harvester mechanical arm comprises a main oil cylinder and a base, the main oil cylinder is mounted on the base at the bottom of the mechanical arm, and swing rack oil cylinders are mounted above the base. The harvester mechanical arm has the advantages that a retraction oil cylinder retractably controls the base to swing at small angles, and the largest inclination angle is 200 degrees; the swing rack oil cylinders mounted on the base retracts and extends in opposite directions to simultaneously drive a central gear to form a swing mechanism, so that the mechanical arm can rotate at 150 degrees relative to the base, and further a relatively large operation area of a harvester can be guaranteed; a large arm and a small arm can perform variable-amplitude or lifting movement through the retraction of the main oil cylinder and auxiliary oil cylinders.
Description
Technical field
The present invention relates to a kind of mechanical arm, particularly a kind of harvester mechanical arm.
Background technology
Mechanical arm is the important component part of forest harvesting combine, and it has determined work capacity and the job area of forest harvesting combine.Under the effect of mechanical arm, felling head can arrive the optional position in job area.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of harvester mechanical arm that can freely control.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of harvester mechanical arm, comprise master cylinder and base, and described master cylinder is installed on described mechanical arm on the base of below, and described base top is provided with revolution oil cylinder with gear racks.
The invention has the beneficial effects as follows: rear push oil cylinder extension and contraction control base is made small angle oscillation, and inclination maximum is 200 °.On seat, there are two revolution oil cylinder with gear racks to stretch in the opposite direction and jointly drive a central gear to form slew gear, make mechanical arm do 150/ rotation with respect to base, guarantee that forest harvesting combine has larger working area; Large arm and forearm carry out luffing and elevating movement by master cylinder and auxiliary oil cylinder flexible.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described revolution oil cylinder with gear racks top is provided with column; The top of described column is provided with connecting rod, on described connecting rod, auxiliary oil cylinder is installed, and described connecting rod below is connected with large arm, and the place ahead of described large arm and connecting rod is provided with forearm, and the tail end of described forearm is provided with telescopic arm.
On the basis of technique scheme, the present invention can also do following improvement.
Further, on the base of described master cylinder, rear push oil cylinder is also installed.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described revolution oil cylinder with gear racks is two.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In accompanying drawing, the list of parts of each label representative is as follows:
1, rear push oil cylinder, 2, master cylinder, 3, base, 4, revolution oil cylinder with gear racks, 5, column, 6, auxiliary oil cylinder, 7, connecting rod, 8, large arm, 9, forearm, 10, telescopic arm.
Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of harvester mechanical arm, comprises that oil cylinder described in master cylinder 2 and base 3,1 is installed on described mechanical arm on the base of below, and described base top is provided with revolution oil cylinder with gear racks 4.Revolution oil cylinder with gear racks top is provided with column 5; The top of described column is provided with connecting rod 7, and auxiliary oil cylinder 6 is installed on connecting rod, and described connecting rod below is connected with large arm 8, and the place ahead of described large arm and connecting rod is provided with forearm 9, and the tail end of described forearm is provided with telescopic arm 10.Rear push oil cylinder 1 is also installed on the base of master cylinder.Revolution oil cylinder with gear racks is two.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
