Description
Technical field
The utility model belongs to tractor field, particularly a kind of fluid pressure type hoisting mechanism.
Background technology
Lifter and hydraulic system are the important component parts of tractor, coordinate the suspension arrangement of tractor to realize mounting the lifting, decline, upset, farm work etc. of farm machinery.Lifter assembly mainly comprises lifter housing assembly, lift cylinder assembly, left and right lift arm assembly, left and right cylinder bracket etc., and lift cylinder assembly is divided into be suppressed hydraulic cylinder assembly and non-ly suppresses hydraulic cylinder assembly.
To suppress oil cylinder be exactly have high pressure liquid force feed all the time in oil cylinder to band, carrys out piston rod drive farm machinery to decline by hydraulic oil, if tractor is when handle keeps down position in working order, suspension arrangement can decline under the effect of high pressure liquid force feed always.Advantage is that farm machinery decrease speed is fast, and suppress and bury to soil suitability by force, operating efficiency is high.But this system exists shortcoming, if ignoring when mounting or dismantle farm machinery the characteristic suppressing oil cylinder, easily producing maloperation, farm machinery are even damaged the person.
Therefore, need now a kind of can realization badly to suppress and the non-hoisting mechanism suppressing two kinds of duties.
Utility model content
The utility model proposes a kind of fluid pressure type hoisting mechanism, suppress oil cylinder when solving mounting or dismounting farm machinery in prior art easily to the even personal problem damaged of farm machinery.
The technical solution of the utility model is achieved in that a kind of fluid pressure type hoisting mechanism, comprise operating mechanism, described operating mechanism is connected with dispenser assembly, described dispenser assembly is connected with lift cylinder assembly by flow divider block, described flow divider block is connected with oil cylinder oil inlet hard tube respectively, oil cylinder oil return hard tube, oil cylinder oil inlet hose assembly and oil cylinder oil return hose assembly, described lift cylinder is provided with rod end chamber, piston rod is provided with in rod end chamber, described piston rod is connected with lift arm assembly, described dispenser assembly is connected with return oil filter by connection rubber tube.
As one preferred embodiment, described dispenser assembly place is provided with stop valve installation, and described stop valve installation is connected with described return oil filter.
As one preferred embodiment, described stop valve installation two ends are respectively equipped with distributor petroleum pipeline and oil return sebific duct, and described distributor petroleum pipeline is connected with described dispenser assembly, and described oil return sebific duct is connected with described return oil filter.
As one preferred embodiment, be provided with O RunddichtringO between described stop valve installation and described distributor petroleum pipeline, described oil return sebific duct is provided with larynx hoop.
As one preferred embodiment, described stop valve installation is normally closed setting.
After have employed technique scheme, the beneficial effects of the utility model are: by increasing a kind of stop valve installation in tractor hydraulic system, easily achieved hydraulic jack suppressed and non-switching of suppressing two kinds of duties by opening or closing of stop valve.Stop valve installation serves the effect of shunting, pressure release, the oil pressure in hydraulic jack is reduced, loses the effect of suppressing, and now relies on the gravity of the farm machinery of suspension naturally to decline, and has a lot of needs will suppress the situation acting on and removing to meet in the actual use of user.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 1 to 3, a kind of fluid pressure type hoisting mechanism, comprise operating mechanism 1, operating mechanism 1 is connected with dispenser assembly 2, dispenser assembly 2 is connected with lift cylinder assembly 4 by flow divider block 7, flow divider block 7 is connected with oil cylinder oil inlet hard tube 6, oil cylinder oil return hard tube 10, oil cylinder oil inlet hose assembly 8 and oil cylinder oil return hose assembly 9 respectively, lift cylinder assembly 4 is provided with rod end chamber, piston rod is provided with in rod end chamber, piston rod is connected with lift arm assembly 3, and dispenser assembly 2 is connected with return oil filter 5 by connection rubber tube 11.
Dispenser assembly 2 place is provided with stop valve installation 12, and stop valve installation 12 is connected with return oil filter 5.
Stop valve installation 12 two ends are respectively equipped with distributor petroleum pipeline 13 and oil return sebific duct 14, and distributor petroleum pipeline 13 is connected with dispenser assembly 2, and oil return sebific duct 14 is connected with return oil filter 5.
Be provided with O RunddichtringO 15 between stop valve installation 12 and distributor petroleum pipeline 13, oil return sebific duct 14 is provided with larynx hoop 16.
Stop valve installation 12 is normally closed setting.
The operation principle of this fluid pressure type hoisting mechanism is: when stop valve installation 12 closes, hydraulic jack is for suppressing duty.When " decline " position got to by operating mechanism 1, hydraulic oil enters oil cylinder oil inlet hard tube 6 by dispenser assembly 2, enter flow divider block 7, oil cylinder oil inlet hose assembly 8 again, then the rod end chamber of lift cylinder assembly 4 is entered, piston rod shortens, lift arm assembly 3 declines, thus control farm machinery decline, hydraulic oil gets back to flow divider block 7 by oil cylinder oil return hose assembly 9 again, then dispenser assembly 2 is entered by oil cylinder oil return hard tube 10, enter return oil filter 5 by connection rubber tube 11 again, then get back in lifter housing, complete a working cycles.
When stop valve installation 12 is opened, hydraulic jack is non-ly suppress duty.When " decline " position got to by operating mechanism 1, hydraulic oil enters oil cylinder oil inlet hard tube 6 by dispenser assembly 2, part hydraulic oil enters flow divider block 7, oil cylinder oil inlet hose assembly 8, then the rod end chamber of lift cylinder assembly 4 is entered, piston rod shortens, lift arm assembly 3 declines, thus control farm machinery decline, hydraulic oil gets back to flow divider block 7 by oil cylinder oil return hose assembly 9 again, then dispenser assembly 2 is entered by oil cylinder oil return hard tube 10, enter return oil filter 5 by connection rubber tube 11 again, then get back in lifter housing.Another part hydraulic oil directly enters return oil filter 5 by stop valve installation 12, then gets back in lifter housing.Stop valve installation 12 serves the effect of shunting, pressure release, the oil pressure in hydraulic jack is reduced, loses the effect of suppressing, and now relies on the gravity of the farm machinery of suspension naturally to decline.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
