Abstract

The utility model relates to a kind of rotary cultivator hydraulic jack, comprise cylinder body, cylinder body comprises cylinder barrel and left and right end cap, also comprise a piston rod and the piston being connected in piston rod top, the guide sleeve to piston rod guiding is provided with in described cylinder barrel, described piston rod penetrates in cylinder barrel by the middle through-hole of guide sleeve, described left and right end cap offers hydraulic fluid port, described piston two ends and guide sleeve two ends are all supported with supporting ring, described guide sleeve inner periphery is provided with seal arrangement, described seal arrangement by be positioned at guide sleeve end face prevent piston rod from inside contracting time impurity brought into the dust ring of Sealing, one O RunddichtringO and shaft seal composition.Compare with existing single-cylinder single-acting rotary cultivator, reliability is high, and cutter rolls rising or falling speed soon and steadily, and tilling depth is reliably spacing, strong operability.

Description

A kind of rotary cultivator hydraulic jack
Technical field
The utility model relates to a kind of hydraulic pressure installation, especially a kind of rotary cultivator hydraulic jack.
Background technique
At present, the lifting of rotary cultivator rotary tillage mechanism generally adopts hoist cylinder to control, and its hoist cylinder is arranged in frame, and piston rod is connected with speed reducer by rod end connecting plate and pin.During rising, driven by the high pressure oil of one-sided injection, piston rod drives the rotary tillage mechanism be connected with speed reducer to rise, and during decline, oil cylinder is inoperative, and workpiece only affects by external force, and rotary tillage mechanism is stressed and rate of descent is uncontrollable, and poor stability, meanwhile, cutter is easily lost.In addition market mostly uses single-cylinder single-acting oil cylinder, single-acting refers to that the motion oil pressure in one of them direction realizes, can only by external force such as deadweight or springs when returning.Single cylinder suspension point, at central point, so not only bears a heavy burden large, and raises up also slow.
Model utility content
This practical purpose is to provide a kind of rotary cultivator hydraulic jack that a kind of control cutter rational in infrastructure, easy to adjust, easy rolls assembly.
For achieving the above object, the utility model adopts following technological scheme: a kind of rotary cultivator hydraulic jack, comprise cylinder body, cylinder body comprises cylinder barrel and left and right end cap, also comprise a piston rod and the piston being connected in piston rod top, the guide sleeve to piston rod guiding is provided with in described cylinder barrel, described piston rod penetrates in cylinder barrel by the middle through-hole of guide sleeve, described left and right end cap offers hydraulic fluid port, described piston two ends and guide sleeve two ends are all supported with supporting ring, described guide sleeve inner periphery is provided with seal arrangement, described seal arrangement by be positioned at guide sleeve end face prevent piston rod from inside contracting time impurity brought into the dust ring of Sealing, one O RunddichtringO and shaft seal composition.
Further, be provided with hole envelope between described piston and cylinder barrel, described piston and piston rod joint are provided with the 2nd O RunddichtringO.
Compare prior art, the beneficial effects of the utility model are: compare with existing single-cylinder single-acting rotary cultivator,
Reliability is high, and cutter rolls rising or falling speed soon and steadily, and tilling depth is reliably spacing, strong operability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model is applied to rotary cultivator.
Wherein, 1, cylinder body; 2, cylinder barrel; 3, piston rod; 4, piston; 5, guide sleeve; 6, hydraulic fluid port; 7, supporting ring; 8, dust ring; 9, an O RunddichtringO; 10, shaft seal; 11, hole envelope; 12, the 2nd O RunddichtringO; 13, hydraulic jack; 14, cutter rolls assembly.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of rotary cultivator hydraulic jack 13 as shown in Figure 1, comprise cylinder body 1, cylinder body comprises cylinder barrel 2 and left and right end cap, also comprise a piston rod 3 and the piston 4 being connected in piston rod 3 top, the guide sleeve 5 that piston rod 3 is led is provided with in cylinder barrel 2, piston rod 3 penetrates in cylinder barrel 2 by the middle through-hole of guide sleeve 5, left and right end cap offers hydraulic fluid port 6, piston 4 two ends and guide sleeve 5 two ends all use supporting ring 7 to support, guide sleeve 5 inner periphery is provided with seal arrangement, seal arrangement by be positioned at guide sleeve 5 end face prevent piston rod 3 from inside contracting time impurity brought into the dust ring 8 of seal arrangement, one O RunddichtringO 9 and shaft seal 10 form.Be provided with hole envelope 11 between piston 4 and cylinder barrel 2, described piston 4 and piston rod 3 joint are provided with the 2nd O RunddichtringO 12.
As described in Figure 2, the hydraulic jack 13 that two the utility model provide, hydraulic jack 13 suspension point is located at the both sides of rotary cultivator attachment respectively, when rotary cultivator attachment promotes, carried out the turnover of control piston 4 by the oil-feed of any one end handling two hydraulic jack 13 hydraulic oil, reach the object that lifting and decline cutter roll assembly 14 simultaneously, in whole process, it is fast that cutter rolls rising or falling speed, facilitates tilling depth to control, strong operability.And this hydraulic jack 13 rolls in the process of assembly 14 more more steady and efficient than one-way cylinder at lifting knife.
Above-mentioned mode of execution is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
