Abstract
The utility model discloses a kind of tractor suspension hoisting devices, it is related to agricultural machinery technological field, including pedestal, oil cylinder, piston, it is characterized by: the pedestal is fixed on the lower rear of tractor, it is provided with the oil cylinder vertically placed up and down on pedestal, piston is provided in oil cylinder, piston upper end is provided with grommet, hawser is installed in ring, the lower end of hawser passes through respectively to be hung in the suspended cross-beam on both sides.The beneficial effects of the utility model are: 1, oil cylinder piston is placed using vertical, hawser pulls suspension arrangement directly up, and have a distinct increment power；2, hydraulic cylinder is thicker, and security performance greatly improves；3, hawser is soft, mitigates or alleviates piston significantly with respect to oil cylinder and left and right or up and down torsion occurs；Therefore, it can fundamentally avoid oil cylinder from bursting the generation of phenomenon, realize the safe and efficient operation of tractor.
Description
Technical field
The utility model relates to agricultural machinery technological fields, are further tractor-mounted lifting devices.
Background technique
The lifting device structure hung after existing tractor is: Hydraulic Cylinder inner arm, and inner arm drives outer arm, outer armband
Dynamic suspension.Its disadvantages are that: hydraulic cylinder is placed using horizontal (or basic horizontal), is pushed out inner arm backward and is driven outer arm
Finally suspension is lifted upwards, thus its thrust is limited.And due to cylinder diameter small (about 6-7 centimetres of diameter), cushion rubber
Small, the pressure that can bear is smaller.Encounter turning especially turned with fast speed when, it is opposite that rear hanger will drive piston
Left and right torsion occurs for oil cylinder；Road conditions it is bad, jolt more serious when, rear hanger will drive piston with respect to oil cylinder occur up and down turn round
Turn；If suspended weights are larger, torsion seriously will cause the generation that oil cylinder bursts accident.If suspension is rotary cultivator afterwards at this time,
Its weight often reaches 300-350 kilograms, oil cylinder is burst will cause afterwards toward contact after an animal-drawn seed plough leg that hangs the hairs of accidents such as fracture
It is raw.
Therefore, the tractor-mounted lifting device for researching and solving safety guarantee is very necessary.
Utility model content
The purpose of this utility model is to provide a kind of tractor suspension hoisting devices, it has strength big, safe and reliable
The characteristics of, it can be achieved that the safe and efficient operation of tractor.
The purpose of this utility model is realized by following scheme:
Tractor suspension hoisting device, including pedestal, oil cylinder, piston, it is characterised in that: the pedestal is fixed on tractor
Lower rear, be provided with the oil cylinder vertically placed up and down on pedestal, piston be provided in oil cylinder, piston upper end is provided with rope
Ring is installed with hawser in ring, and the lower end of hawser passes through respectively to be hung in the suspended cross-beam on both sides.
Further,
There are two the grommets.
Described two grommets are set in horizontal support, and horizontal support is set to piston upper end.
Oil-through-hole is provided on the oil cylinder, oil-through-hole connects oil pump by oil pipe.
The oil cylinder, piston take vertical placement.
The oil cylinder, piston take 0 ° -25 ° vertical placements of leaning forward.
The beneficial effects of the utility model are: 1, placed using vertical due to tractor suspension hoisting device, hawser is straight
It connects and is pulled along suspended cross-beam upwards, so that suspension arrangement is driven, thus the power that has a distinct increment；After tested, the utility model sample
Machine lifting force reaches 500 kilograms or more.2, the hydraulic cylinder of the utility model is thicker, and diameter reaches 9 centimetres (can also fit as needed
When increase), therefore, security performance greatly improves.3, due to the flexibility of hawser, turning is being encountered especially with faster
When degree turning, or road conditions it is bad, jolt more serious when, can mitigate or alleviate significantly piston and occur or so with respect to oil cylinder or upper and lower
Torsion.To sum up, the utility model can fundamentally avoid oil cylinder from bursting the generation of phenomenon, realize the safe and efficient operation of tractor.
In order to make those skilled in the art better understand the scheme of the utility model, and make the above-mentioned mesh of the utility model
, feature and advantage can be more obvious and easy to understand, the utility model is made with reference to the accompanying drawings and examples further details of
Explanation.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
In figure: 1 is suspended cross-beam, and 2 be lift lever, and 3 be oil-through-hole, and 4 be hawser, and 5 be piston, and 6 be grommet, and 7 be cross
Support, 8 be oil cylinder.
Specific embodiment
As shown in Figure 1, tractor suspension hoisting device, including pedestal, oil cylinder 8, piston 5, it is dilatory that the pedestal is fixed on
The lower rear of machine is provided with oil cylinder 8 on pedestal, piston 5 is provided in oil cylinder 8, there is horizontal support 7 in 5 upper end of piston, sets in horizontal support 7
Two grommets 6 in left and right are equipped with, are installed with hawser 4 in grommet 6, the lower end of hawser is individually fixed in the suspended cross-beam 1 on both sides.
Lift lever 2 is hinged in suspended cross-beam 1.Oil-through-hole 3 is provided on oil cylinder 8, oil-through-hole 3 connects oil pump by oil pipe.Two ropes
Ring 6 is respectively arranged at left and right ends portion in horizontal support 7, on the one hand makes strength greater role in suspended cross-beam 1, is on the other hand convenient for
Two suspended cross-beams 1 are controlled not to be swung left and right.
The oil cylinder, piston can take vertical placement；It can also take and lean forward and (lean forward and refer to oil cylinder, upper piston area to dragging
Draw heading inclination) 0 ° -25 ° it is vertical place, may further take lean forward 5 ° -20 ° it is vertical place, further can be with
Take 10 ° -20 ° vertical placements of leaning forward.
When needing tractor to draw trailer transport, farm implements are unloaded, towing pad are tangled into trailer, the quick coupling in oil overhold
The quick coupling of trailer is directly connect, oil is led to.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, the change that can be readily occurred in
Change or replace, should be covered within the scope of the utility model.
