Abstract
The utility model discloses a hydraulic hoister for a tractor, which comprises lift arms and a swinging shaft, wherein the lift arms are fixedly arranged at both ends of the swinging shaft which is provided with a support frame which is fixedly arranged on the rear side of the upper part of the box body of the gearbox of the tractor; the swinging shaft is also provided with a swing arm which forms an included angle with the lift arm and can swing along with the lift arm; the front side of the box body of the gearbox of the tractor is fixedly provided with a hydraulic cylinder support seat which is hinged on the cylinder body of a hydraulic cylinder; the swing arm is hinged on the piston rod of the hydraulic cylinder which is communicated with an oil tank and a hydraulic oil passage which are special for the hoister and are arranged on a tractor body. The utility model solves the problem that the hoister in use is easy to generate internal leakage which enables the hoister to work abnormally; the utility model has the advantages of reliable operation and convenient maintenance, has three operational states of strong lift when adopting a double-acting oil cylinder, strong drop and float, and can be widely used for medium and small-sized tractors.
Description
Technical field
The utility model relates to the lifter technical field, relates in particular to a kind of hydraulic rockshaft that is used for tractor.
Background technology
At present, the employed lifter of tractor with small four wheels mostly is that hydraulic cylinder is placed in the housing, and the base plate of this housing is connected by bolt with gear box of tractor, and hydraulic medium is housed in the housing.During work, piston reaches the purpose of lifting farm machinery thereby the interior lift arm of promotion lift arm outside swinging axle rotates drive rotates under the promotion of hydraulic medium.This lifter can produce oil leakage phenomenon at the base plate place that combines with gear box of tractor, i.e. " interior leakage ".After the leakage of oil,, can not in time be found, can make the lifter lifting ineffective, even hydraulic pump is damaged because hydraulic cylinder is built in enclosure interior.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of a kind of hydraulic pressure elevator of tractor reliable, easy to maintenance that uses is provided, solves lifter and in use be easy to generate " interior leakage ", cause the problem of lifter cisco unity malfunction.
For achieving the above object, the technical solution of the utility model is: a kind of hydraulic pressure elevator of tractor, comprise lift arm, can be around the swinging axle of self axis swing, lift arm is fixedly installed on the swinging axle two ends, swinging axle is provided with bracing frame, bracing frame is fixedly set in gear box of tractor casing top rear side, swinging axle also is provided with the swing arm that can swing with lift arm that has angle with lift arm, gear box of tractor casing front side is fixed with the hydraulic cylinder bearing, the cylinder body of hydraulic cylinder bearing and hydraulic cylinder is hinged, and the piston rod of swing arm and hydraulic cylinder is hinged, and hydraulic cylinder is by distributor and the special-purpose fuel tank of lifter that is arranged on the tractor body, the hydraulic pump oil circuit is communicated with.
Owing to adopted technique scheme, during use, in cylinder body, move back and forth by oil circuit control hydraulic cylinder piston rod, promote the swing arm hinged and swing, thereby drive the lift arm swing around swinging axle with it, realize articulating the lifting of farm machinery.The bracing frame of swinging axle is arranged at gear box of tractor casing top rear side, hydraulic cylinder is communicated with by the special-purpose fuel tank of distributor and lifter, hydraulic pump oil circuit, the lifter fuel tank is special-purpose, so fundamentally solved the problem that lifter produces " interior leakage " in use.Hydraulic cylinder and bracing frame all are located at the top of gear box of tractor, are convenient to inspection and maintenance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment
Embodiment
As shown in drawings, a kind of hydraulic pressure elevator of tractor, comprise lift arm 4, can be around the swinging axle 3 of self axis swing, lift arm 4 is fixedly installed on swinging axle 3 two ends, swinging axle 3 also be provided with lift arm 4 have angle can with the swing arm 7 of lift arm 4 swing, swing arm 7 is made as one with lift arm 4 and is fixed on the swinging axle 3.Swinging axle 3 is provided with bracing frame 2, bracing frame 2 is fixedly set in gear box of tractor 1 casing top rear side, gear box of tractor 1 casing front side is fixed with hydraulic cylinder bearing 8, hydraulic cylinder bearing 8 is hinged with the cylinder body 51 of hydraulic cylinder 5, swing arm 7 is hinged with the piston rod 52 of hydraulic cylinder 5, and hydraulic cylinder 5 is communicated with (distributor, hydraulic pump, lifter special use fuel tank are not shown) by distributor with the special-purpose fuel tank of the lifter on being arranged at tractor body, hydraulic pump oil circuit.When adopting double acting hydraulic cylinder,, realize that tractor articulates the pressure rising of farm machinery and forces to descend promptly so-called " strong liter falls by force " by the different oil pockets of distributor control hydraulic cylinder 5.Distributor also can be provided with " floating " state, relies on the farm machinery of land wheel depthkeeping to provide convenience for the user uses.
During use, the piston rod 52 of controlling hydraulic cylinder 5 by oil circuit moves back and forth in cylinder body 51, promotes the swing arm 7 hinged with it around swinging axle 3 swings, thereby drives lift arm 4 swings, realizes articulating the lifting of farm machinery.The bracing frame 2 of swinging axle 3 is arranged at gear box of tractor 1 casing top rear side, hydraulic cylinder 5 is communicated with by the special-purpose fuel tank of distributor and lifter, hydraulic pump oil circuit, the lifter fuel tank is special-purpose, so fundamentally solved the problem that lifter produces " interior leakage " in use.Hydraulic cylinder 5 and bracing frame 2 all are located at the top of gear box of tractor 1, are convenient to inspection and maintenance.
Because hydraulic cylinder 5 can take off from tractor more conveniently, therefore, the user can in officely what is the need for to " push away " or the position of " drawing " on hydraulic cylinder 5 is linked to each other with facility, such as, the tractor front end is loaded onto dozer, as long as hydraulic cylinder is installed to suitable position, connects good hydraulic hose, just can be used for doing work such as level land, soil-shifting, platform is provided for user's second use hydraulic means.
