Accurate application of different types of handling devices for agricultural tractors

The tractor hydraulic suspension can be divided into three types: semi-separated hydraulic system, integral hydraulic system and split hydraulic system.

First, semi-separated hydraulic system holding device accurate application

The handle should be accurately matched to the application. When applying force to adjust the cultivation, the position adjustment handle should be placed in the promotion position first, and the height of the agricultural implement promotion is determined by the promotion position of the position adjustment handle, and only the force adjustment handle is used to lift the agricultural implement. After selecting the appropriate tillage depth by the test plow, the force adjustment handle should be immediately blocked by the positioning handwheel to ensure that the handle is moved to the same position every time, so that the depth of each plow is consistent.

When applying the position adjustment work, the force adjustment handle should be placed in the highest promotion position first. Only the position adjustment handle is used to lift the agricultural implement. After the fall position and promotion status of the agricultural implement are selected, the positioning of the hand wheel adjustment adjustment handle can be distinguished.

When the agricultural implement is suspended for long-distance transportation, after the agricultural implement is upgraded to the transportation position, the handle is locked by the positioning handle, and the landing speed adjustment hand wheel should be screwed to the end so that the oil draining passage of the cylinder is passed away, and the agricultural implement is locked in the transportation. In order to avoid accidental negligence, the handle is pulled to cause an accident.

When hydraulic transmission is not required, it is forbidden to pull the position adjustment handle to the hydraulic output area to prevent the safety valve from opening frequently, causing oil pump wear and power loss.

Second, the accurate application of the separate hydraulic system holding device

When you are promoted, you should let the handle board rise to the promotion status and then let the handle jump back to neutral status when the agricultural implement reaches the highest promotion status.

When the farm implements landing or the agricultural implements perform the height adjustment of the tillage, the handle plate should be in a floating position, and when the distribution valve is in a floating position, it will not actively jump back to the neutral position.

The strong drop effect is a unique function of the double-acting cylinder, and is generally used as a transition state of the agricultural implement. The forced handle should not stay in the strong down position for a long time. Otherwise, the agricultural implement will be forced to land. If the tractor is jacked up, the underside of the cylinder will be broken by excessive pulling force.

Neutral state farming should generally not be applied, as this is a disguised level adjustment. It exposes the high-pressure hose to a large amount of extra cumbersome and easily damages the hose.

When the handle is pulled from one position to another, it is not suitable to stop between the two, otherwise the oil pump will be overloaded due to poor future.

Third, the accurate application of the overall hydraulic system holding device

The integral hydraulic system is to install the hydraulic components such as the power part, the control part and the working part in a hydraulic system, and form a hydraulic system as a whole. It does not have a separate fuel tank and the working fluid used is the gear oil in the rear axle.

The lifting of agricultural tools. The fan-shaped outer handle is fixed in the shallow and deep area, and the inner handle is pulled to the fast character position of the sector plate, and the agricultural implement falls faster. If the position of the slow word is reached, the farm implements a slower landing. When the inner handle is placed in a different position in the rising and falling area of ​​the sector plate, the implements are correspondingly maintained at different ground heights.

When the tillage is adjusted vigorously, the inner handle is selected to have a suitable landing speed in the fast and slow section, and the outer handle is selected in the deep shallow section to select the desired depth of cultivation. Later, when the ploughing and ploughing are carried out on the ground, only the inner handle is used for lifting and lowering, and the outer handle is generally not changed greatly.

When working with the position adjustment, the inner handle is held in the lift-down section, and the outer handle should be placed deep below the sector plate.

When the agricultural implement is suspended for land transfer, the internal handle should be placed in the highest promotion position and locked with the positioning hand wheel to keep the agricultural implement in the transportation position. The outer handle should be in the deep shallow section. Do not pull both handles up. Since the outer handle is in the hydraulic output position, the dispensing valve cannot return to the neutral position, and the result will force the safety valve to open.

When using hydraulic output, the inner handle should be fast and slow; select the drop speed in the segment. The outer handle is pulled up to the hydraulic output position. If the outer handle is pushed forward slightly, it is the neutral state of the split cylinder. If the outer handle is moved forward more, the sub-cylinder landing process is divided.

When the hydraulic pump is not applied, the hydraulic pump eccentric shaft clutch handle should be moved to the off position to avoid unnecessary wear of the precision parts due to the idling of the hydraulic pump. When holding the hydraulic pump eccentric shaft clutch handle, the clutch must be stepped to the end.

4. Semi-separated hydraulic system holding device accurately applied

The handle should be accurately matched to the application. When applying force to adjust the cultivation, the position adjustment handle should be placed in the promotion position first, and the height of the agricultural implement promotion is determined by the promotion position of the position adjustment handle, and only the force adjustment handle is used to lift the agricultural implement. After selecting the appropriate tillage depth by the test plow, the force adjustment handle should be immediately blocked by the positioning handwheel to ensure that the handle is moved to the same position every time, so that the depth of each plow is consistent.

When applying the position adjustment work, the force adjustment handle should be placed in the highest promotion position first. Only the position adjustment handle is used to lift the agricultural implement. After the fall position and promotion status of the agricultural implement are selected, the positioning of the hand wheel adjustment adjustment handle can be distinguished.

When the agricultural implement is suspended for long-distance transportation, after the agricultural implement is upgraded to the transportation position, the handle is locked by the positioning handle, and the landing speed adjustment hand wheel should be screwed to the end so that the oil draining passage of the cylinder is passed away, and the agricultural implement is locked in the transportation. In order to avoid accidental negligence, the handle is pulled to cause an accident.

When hydraulic transmission is not required, it is forbidden to pull the position adjustment handle to the hydraulic output area to prevent the safety valve from opening frequently, causing oil pump wear and power loss.
