Abstract
The utility model relates to an accessory of agricultural machinery, in particular to a tractor lifter. The tractor lifter comprises a lifting arm hinged shaft and lifting arms fixedly connected to the two ends of the lifting arm hinged shaft. The lifting arm hinged shaft is pivoted with the interior of a shell; a hydraulic cylinder is installed in an inner cavity of the shell; an ejection rod of the hydraulic cylinder is hinged to the lifting arm hinged shaft; an oil return opening communicated with a hydraulic pump is formed in the inner cavity of the shell, and is formed in the front end of the shell and the lateral side of the lifting arm hinged shaft; an installment plate is arranged in the inner cavity of the shell; the cylinder body of the hydraulic cylinder is inserted in the installment plate; a rocking rod is fixedly installed on the lifting arm hinged shaft in the inner cavity of the shell; the top end of the ejection rod of the hydraulic cylinder is hinged to the upper end of the rocking rod through a hinged shaft. Because the steel hydraulic cylinder is adopted, the lifter is long in service life; meanwhile, because the size and the installment volume of the steel hydraulic cylinder are reduced, improvement of working efficiency of the lifter is facilitated; the reasonable installment structure of the hydraulic cylinder and the shell of the lifter contribute to prolonging the overall service life of the lifter.
Description
Technical field
The utility model relates to a kind of agricultural machinery accessory, a kind of tractor lifting mechanism specifically.
Background technology
Tractor is in the process of using, need to promote or fall with the farm implements that lifter is pulled rear tractor, in order to utilize farm implements to carry out operation, existing lifter is because structural design section is reasonable, the hydraulic jack housing is the cast iron manufacturing, causes bulkyly, and the lifter housing can hold the narrow space of hydraulic oil, operating efficiency is low, and hydraulic jack is short service life.Be particularly useful for fraction horsepower tractor in bel-drivenn.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, operating efficiency is high, the tractor lifting mechanism of long service life.
The utility model is that the technical scheme that the technical solution problem adopts is:
Tractor lifting mechanism described in the utility model comprises the lift arm hinge and is fixedly connected on the lift arm at lift arm hinge two ends, described lift arm hinge is articulated in housing, in the inner chamber of described housing, hydraulic jack is installed, the push rod of hydraulic jack and lift arm hinge are hinged, be provided with the oil return opening that is communicated with hydraulic pump in the inner chamber of housing, described oil return opening is arranged on the front end of housing, the side of lift arm hinge, it is characterized in that: be provided with the installation installing plate in the inner chamber of described housing, the cylinder body of hydraulic jack is inserted on installing plate; Be installed with fork on lift arm hinge in the inner chamber of housing, the push rod top of hydraulic jack is hinged on the upper end of fork by hinge.
Be positioned on the housing of lift arm hinge below with recessed portion.
At least be communicated with the through hole of installing plate both sides at installing plate with a place with the junction of inner walls.
Be positioned on the outer wall of housing of hydraulic jack rear end and be installed with liquid pressure transducer, the oil-in of described liquid pressure transducer is connected to the hydraulic pressure delivery side of pump, and the working end of liquid pressure transducer is connected to the oil-in of hydraulic jack.
Owing to having adopted said structure, tractor lifting mechanism described in the utility model adopts steel hydrocylinder, long service life, steel hydrocylinder has reduced own vol and installation volume simultaneously, dischargeable capacity in the tractor lifting mechanism housing enlarges, be conducive to improve its operating efficiency, the hydraulic jack mounting structure of appropriate design and lifter shell help to extend the whole service life of lifter.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
As shown in the figure, tractor lifting mechanism described in the utility model comprises lift arm hinge 1 and is fixedly connected on the lift arm 2 at lift arm hinge 1 two ends, described lift arm hinge 1 is articulated in housing 3, hydraulic jack 5 is installed in the inner chamber of described housing 3, described hydraulic jack 5 adopts steel shell, reduces volume, increases the service life.The push rod of hydraulic jack 5 and lift arm hinge 1 are hinged, be provided with the oil return opening 10 that is communicated with hydraulic pump in the inner chamber of housing 3, described oil return opening 10 is arranged on the front end of housing 3, the side of lift arm hinge 1, be provided with in the inner chamber of described housing 3 installing plate 8 is installed, the cylinder body of hydraulic jack 5 is inserted on installing plate 8; Be installed with fork 6 on lift arm hinge 1 in the inner chamber of housing 3, the push rod top of hydraulic jack 5 is hinged on the upper end of fork 6 by hinge.
Be positioned on the housing 3 of lift arm hinge 1 below with recessed portion 4.Recessed portion 4 can make the installation site of lift arm hinge 1 move down and enlarge the internal volume of housing 3, make hydraulic jack 5 level installation as far as possible, and when the push rod of hydraulic jack 5 is flexible, the amplitude of upper and lower swing is less, is conducive to extend the service life of hydraulic jack 5.
At least be communicated with the through hole 9 of installing plate 8 both sides at installing plate 8 with a place with the junction of housing 3 inwalls.Through hole 9 the circulation that can accelerate installing plate 8 both sides hydraulic oil is set, be conducive to improve the operating efficiency of lifter.
Be positioned on the outer wall of housing 3 of hydraulic jack 5 rear ends and be installed with liquid pressure transducer 7, the oil-in of described liquid pressure transducer 7 is connected to the hydraulic pressure delivery side of pump, and the working end of liquid pressure transducer 7 is connected to the oil-in of hydraulic jack 5.Whether the hydraulic oil that the arranging of this liquid pressure transducer 7 can be controlled hydraulic pump drive the injecting lift device, in the time of the work of needs lifter, liquid pressure transducer 7 is transformed into duty, the hydraulic oil of hydraulic pump output can enter hydraulic jack 5 by liquid pressure transducer 7, drives hydraulic jack 5 work; Otherwise, if do not need lifter work, but when other external hydraulic tool work, can with the liquid pressure transducer 7 external output states of conversion, hydraulic oil be outputed on other hydraulic tools by liquid pressure transducer 7 and external conduit under fluid pressure.
The structure of liquid pressure transducer 7 and operation principle are common practise, this auspicious stating no longer.
