Abstract
The utility model discloses a kind of hydraulic rockshafts, including spindle box, the spindle box lower end is provided with support shaft, there are two hydraulic cylinders for extension upper end setting at left and right sides of the support shaft, the hydraulic cylinder upper end is by supporting connector to connect with support arm, the support arm is connect with the second axle box for being located at the spindle box upper end, and the utility model solves the problems, such as that tractor lifting force is inadequate in the prior art.
Description
Technical field
The utility model relates to machinery equipment field more particularly to a kind of hydraulic rockshafts.
Background technique
In the prior art, hydraulic cylinder is one, or is arranged in cabinet, this just greatly limits the size of oil cylinder,
To which the pressure generated to oil cylinder produces limitation, so that farm implements lifting force is inadequate.
Utility model content
The purpose of the utility model is to provide a kind of hydraulic rockshafts, solve tractor lifting mechanism lifting force in the prior art
Insufficient problem.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of hydraulic rockshaft of the utility model, including spindle box, the spindle box lower end are provided with support shaft, the branch
The extension upper end setting at left and right sides of axis is supportted there are two hydraulic cylinder, the hydraulic cylinder upper end by support connector with
Support arm connection, the support arm are connect with the second axle box for being located at the spindle box upper end.
Further, the support arm is to be flexibly connected with second axle box, and the support arm can be described hydraulic
The flexible direction rotation of oil cylinder.
Further, the hydraulic cylinder and the support connector are hinged.
Further, the end of the support arm is equipped with the lantern ring for connecting tractor hoisting frame.
Compared with prior art, the advantageous effects of the utility model: in the prior art, hydraulic cylinder is one, or
Person is arranged in cabinet, this just greatly limits the size of oil cylinder, so that the pressure generated to oil cylinder produces limitation, so that agriculture
It is inadequate to have lifting force, two hydraulic cylinders of the utility model are arranged on the outside of spindle box, can increase hydraulic oil to a certain extent
The power of cylinder is with a wide range of applications so that tractor lifting mechanism lifting force is bigger.
Detailed description of the invention
The utility model is described in further detail for explanation with reference to the accompanying drawing.
Fig. 1 is the utility model rearview；
Fig. 2 is the utility model left view；
Description of symbols: 1, support arm；2, connector is supported；3, hydraulic cylinder；4, support shaft；5, the second axle box；6,
Spindle box；7, lantern ring.
Specific embodiment
As shown in Figs. 1-2, a kind of hydraulic rockshaft, including spindle box 6,6 lower end of spindle box are provided with support shaft 4,
There are two hydraulic cylinders 3 for the extension upper end setting of 4 left and right sides of support shaft, and 3 upper end of hydraulic cylinder passes through branch
Support connector 2 is connect with support arm 1, and the support arm 1 is connect with the second axle box 5 for being located at 6 upper end of spindle box.
The support arm 1 is to be flexibly connected with second axle box 5, and the support arm 1 can be stretched in the hydraulic cylinder 3
The direction of contracting rotates.
The hydraulic cylinder 3 and the support connector 2 are hinged.
The end of the support arm 1 is equipped with the lantern ring 7 for connecting tractor hoisting frame
The action process of the utility model is as follows:
When tractor driving hydraulic cylinder 3 works, the flow direction of hydraulic oil is controlled by operating mechanism, so that hydraulic
Oil cylinder 3 generates expanding-contracting action, and lift arm 1 is driven to rotate relative to the second axle box 5, and the end of lift arm 1 connects farm implements hoisting frame,
To realize the lifting of agricultural machinery and implement.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model
Range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are practical new to this
The various changes and improvements that the technical solution of type is made should all fall into the protection scope that the utility model claims book determines
It is interior.
