Abstract
The utility model discloses a small four-wheel tractor with a hydraulic steering mechanism and belongs to the technical field of agricultural machinery. The small four-wheel tractor is characterized in that a fixing plate is mounted on a main beam of the small four-wheel tractor; a cylinder is fixed on the main beam through the fixing plate; the front end of a cylinder piston rod is connected with a steering lever on the front axle; a hydraulic steering device is arranged on the lower part of the steering wheel; an oil outlet, an oil inlet and an oil return port of the hydraulic steering device are respectively connected with an oil inlet of the cylinder, an oil outlet of the oil pump and an oil tank; a high-pressure oil pump is arranged on the right side of the driver's seat; a belt pulley of the oil pump is connected with a small belt pullet on a gearbox through a V-shaped belt; and the oil tank is arranged behind the driver's seat. The small four-wheel tractor has the beneficial effects that the steering mechanism can be simplified by employing hydraulic steering, and the small four-wheel tractor is simple in structure, low in fault rate, labor-saving to operate and convenient to repair and maintain.
Description
Technical field
The utility model belongs to agricultural machinery technological field.
Background technology
At present, the steering hardware of known small four-wheel tractor is that employing is mechanical, this steering hardware complex structure, and fault is many, and the operation sensivity is poor, the operation effort.
Summary of the invention
The purpose of this utility model is: a kind of small four-wheel tractor with hydraulic steering mechanism is provided, and it adopts fluid-link steering, has simplified steering hardware.
The technical solution of the utility model is: an adapter plate is installed on the girder of small four-wheel tractor, oil cylinder is fixed on girder by adapter plate, the front end of cylinder piston rod is connected with the steering lever on propons.A hydraulic steering gear is installed in bottom at bearing circle, and the oil outlet of hydraulic steering gear, oil inlet, return opening are connected with the oil inlet of oil cylinder, oil outlet and the fuel tank of oil pump respectively.At the right side of operator's saddle installation high-voltage oil pump, the oil pump belt pulley is connected with the V band with the small belt pulley on change speed gear box, and fuel tank is arranged on the back of operator's saddle.
The beneficial effects of the utility model are, adopt fluid-link steering can simplify steering hardware, simple in structure, fault is few, rapid operation, and maintenance is convenient.
The accompanying drawing explanation
Fig. 1 is birds-eye view of the present utility model.
Fig. 2 is hydraulic transmission principle figure of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
In figure: 1. girder, 2. driving engine, 3. propons, 4. front-wheel, 5. engine belt pulley, 6.V band A, 7. change speed gear box big belt pulley, 8. change speed gear box small belt pulley, 9. change speed gear box, 10.V is with B, 11. the oil pump belt pulley, 12. high-pressure oil pumps, 13. oil pipe A, 14. fuel tanks, 15. operator's saddle, 16. trailing wheels, 17. oil pipe B, 18. oil pipe C, 19. bearing circle, 20. hydraulic steering gears, 21. adapter plates, 22. oil pipe D, 23. oil cylinder, 24. oil pipe E, 25. piston rods, 26. steering levers.
In Fig. 1, the upper adapter plate (21) of installing of girder (1), be fixed on girder (1) with adapter plate (21) by oil cylinder (23) upper, and the front end of cylinder piston rod (25) is connected with the steering lever (26) on propons (3).A hydraulic steering gear (20) is installed in bottom at bearing circle (19), at the right side of operator's saddle (15) installation high-voltage oil pump (12), oil pump belt pulley (11) on high-pressure oil pump (12) is with B(10 with the change speed gear box small belt pulley (8) on change speed gear box (9) with V) be connected, change speed gear box big belt pulley (7) is with A(6 with engine belt pulley (5) with V) be connected, fuel tank (14) is arranged on the back of operator's saddle (15).
Its principle of work is as follows: high-pressure oil pump is extracted the hydraulic oil in fuel tank, pressurize out, is transported to hydraulic steering gear, the hydraulic steering gear steering wheel operating, and hydraulic oil is delivered to oil cylinder, make the piston rod telescopic moving.Piston rod pulls steering lever, reaches the effect turned to.
