A few questions about how the bulldozer operates

According to the project of the operation (such as leveling the land, digging the soil and building the lake, moving the mountain and filling the ditch, etc.), the scope, the terrain and landform, etc., carefully design and select the most reasonable operation method and walking route, and strive to operate less empty travel, less pulling the joystick, straight driving and pushing, safe operation, efficient and high-quality.

When bulldozing, the fuselage should first stop and swing steadily, gently put the shovel, and the depth of soil and the amount of soil should be roughly the same; The advance speed should be slightly slower to avoid excessive impact or slippery blades; It's important to be attentive and adaptable at work, for example, when you see the front of the car tilting up (the blade is down), and when the front of the car is down, you can lift the handle with your hand (the blade is raised).

When bulldozing is not smooth, for example, when encountering hard soil or other obstacles, do not blindly push hard with a large throttle, do not jerk the clutch and hit hard, and also avoid forcing bulldozing with the side of the shovel to avoid serious consequences.

The bulldozer is in the wilderness all the year round, the ground is hard, the terrain is complex and the treacherous environment, in the ultra-short distance very frequently in the advance and retreat, in the heavy load state, difficult operation, it is very easy to cause the early wear, deformation, damage, fastener loosening of the tractor chassis and bulldozer blade parts, therefore, in addition to the correct operation, the inspection and maintenance of the above parts can not be negligent; The cutting edge of the bulldozer blade should be kept sharp, and one side of it can be used after being blunted, and both sides are seriously worn, and the edge can be sharpened by surfacing welding, or simply replaced.

Brother, you came to this is the dungeon and the warrior game frequency, as for the bulldozer to see the terrain, the hard ground is good, the mud is difficult, there are ups and downs, this depends on the feeling and field experience, as for the butter hole, I don't know, personal opinion,

1.When the bulldozer goes uphill and downhill, its slope shall not be greater than 30°; When working on a cross slope, the cross slope shall not be greater than 10°. When going downhill, it is advisable to use backwards and down, it is strictly forbidden to slide in neutral gear, and the blade can be put down to assist braking if necessary.

2.When working on steep slopes and high ridges, there must be a special person to command, and it is strictly forbidden for the shovel blade to exceed the edge of the slope. At the end of the soil delivery, it should be changed to reverse gear before lifting the shovel.

3.In the trench operation of the vertical slope, the trench depth shall not exceed 2m for large bulldozers, and shall not exceed 2m for small bulldozers, and the bulldozer blade shall not push solitary stones or large soil blocks on the slope wall higher than the fuselage.

4.When the bulldozer picks up and unloads the bulldozer blade, it must consider the convenience of the next hanging, and the auxiliary personnel should cooperate closely with the driver when picking the blade.

5.When multiple machines operate on the same working face, the distance between the front and rear machines should not be less than 8m, the distance between the left and right should be greater than, when two or more bulldozers work side by side, the distance between the blades of the two bulldozers should be maintained at 20 30cm, and the bulldozer must move forward at the same speed in a straight line; When reversing, they should be in order to prevent collisions.

6.When using a bulldozer to cut down a large tree or remove a broken wall, the focus point should be increased to prevent the upper part from falling in reverse.

In other words, it is not allowed to operate a bulldozer without a bulldozer operator license.

Bulldozer operation application conditions:

1. Be at least 18 years old and not exceed the statutory retirement age;

2. Have a junior high school education or above (special operations personnel should have a high school education or equivalent to high school or above);

3. Be in good health, without other and physiological defects such as vertigo that hinder the operation;

4. Have the necessary safety technical knowledge and skills;

5. Other conditions stipulated in the corresponding special operations.

Beginner bulldozer tutorial:

First of all, the front of the right-hand side is to control the front pressure of the dozer, the dozer shovel is pressed down and pulled backward to pull the dozer upward, and the left and right are to control the tilt of the dozer.

Second, the ripper is controlled left and right. The left-hand side is pulled back and forth to control the throttle, not to mention the steering and gear. Under the foot is the brake and idle throttle.

Third, the idle throttle is to press the throttle to become lower, and there are two brakes, which are generally stepped on together, and sometimes you need to step on the brakes when you steer, and you need to step on the brakes on that side when you turn. Note that when going downhill, the steering must be applied to the brakes, otherwise the steering will be reversed.

The bulldozer is a behemoth and is indispensable in construction. In the construction of farmland capital construction, water conservancy and other construction, bulldozing operation is an important content, and the driver should pay attention to the following points in the operation:

1. According to the characteristics of the terrain and the requirements of the operation project, use different bulldozing methods correctly and flexibly to improve the efficiency of bulldozing operations.

2. When manipulating the handle of the distributor during the work, it should be correct and agile, so as to avoid the slide valve blocking the oil circuit, making the oil pressure abnormally high, forcing the safety valve to open, and making the parts at a higher pressure. At the same time, during the lifting and lowering operation of the bulldozer blade, the distributor handle should automatically return to the "neutral" position, and it should not be forced not to return to its position. If the handle does not return to the "neutral" position, the oil pressure will exceed the opening pressure of the safety valve, causing the oil to drain and a "buzzing" sound can be heard near the distributor.

At this point, you can force the dispenser handle back to the "neutral" position. Then check the cause of the failure, otherwise the hydraulic components will be damaged.

3. When the parking or hydraulic system is not working and during the idle stroke of the bulldozer blade, the distributor handle should be placed in the "neutral" position to avoid the spring being compressed and causing early fatigue damage.

4. In the process of transportation of the bulldozer (such as the transfer of the operation site), it should be noted that after the bulldozer is raised to the transportation height, it should be slightly fixed with a safety plug to make the shovel hanging on the front bracket of the tractor to reduce the load of the hydraulic hose and cylinder. And put the handle of the oil pump transmission device in the "separate" position to stop the oil pump from working to reduce its wear.

5. When the bulldozer turns and crosses the ditch at the head of the ground, it should have a low speed and a small throttle to avoid the hydraulic hose from breaking due to the large impact force.

6. When bulldozing, the handle of the distributor should be placed in the "floating" position. In order to avoid overloading the locomotive or encountering obstacles such as hard soil layers and stones, the oil pressure in the high-pressure hose will increase sharply, causing the hose to burst. When placed in a floating position, it can be raised and lowered freely to avoid overloading caused by the blade when it hits uneven hard soil or obstacles.

7. During bulldozing operations, the locomotive should keep running in a straight line as much as possible, and it is strictly forbidden to make sharp turns in the process of "pressure drop" (shovel blade into the soil). In order to avoid damage to the blade and beam frame, the cylinder bracket will be bent and broken. During operation, the locomotive must be fully raised before the locomotive can turn.

After a long time, it will naturally be pushed flat, and it is necessary to feel the bulldozer to master the blade. As for leveling, the following points are summarized: 1. Look at or feel the up and down changes of the front of the car, if the front of the car is slightly winged up and down the blade a little, the front of the car is inclined down to lift the shovel a little.

2. The amplitude of the shovel up or down should be small, that is to say, when pulling the handle of the shovel, it should not be pulled too hard, the shovel should be lowered a little gently, and the shovel should be raised gently a little, and the action should be fast. 3. Push a shovel of a relatively flat foundation first, and then push it along this flat foundation like this, just like painting, according to the real object to draw out. 4, with a high-frequency and low-amplitude shovel "shake" action to improve, that is, when holding the hydraulic handle of the hand keep shaking and shaking, I used to drive 120 and 140 has always been like this, many bulldozer drivers will usually use the action of shaking, the effect is very good, but I now drive 160 flat will not be so shaking, because the 160 hydraulic handle device is different, and the jitter action is suitable for opening with 2 gears, because 1 gear is too slow, coherent.

5. The combination of people and vehicles into one, that is to say, the whole time is devoted to the whole body, and the mood reaches a state of forgetfulness. Okay, I've thought about this for the time being, I hope it will help you.

In other words, it is not allowed to operate a bulldozer without a bulldozer operator license.

When bulldozing, the fuselage should first stop and swing steadily, gently put the shovel, and the depth of soil and the amount of soil should be roughly the same; The advance speed should be slightly slower to avoid excessive impact or slippery blades; It's important to be attentive and adaptable at work, for example, when you see the front of the car tilting up (the blade is down), and when the front of the car is down, you can lift the handle with your hand (the blade is raised). 1. Before starting, the main clutch must be disengaged, the gear lever and the advance and retreat lever must be placed in the neutral position, the fuel adjustment lever must be placed in the low-speed or non-fuel supply position, and the pressure reducing lever must be placed in the decompression position.

2. Insert the electric key into the lock and twist it in a clockwise direction to the "start" position, after the engine starts. When the electric key is pulled counterclockwise to the "running" position. Pull up the pressure relief lever (if fitted) and turn the key switch to the switch to the "start" position, turn it.

3. If the first start is unsuccessful, you should wait for two minutes to restore the battery, and then start the second time (the time to press the start button should not exceed 15 seconds).

4. In cold climate, the start should be preheated first, and the glow plug should be turned to the "on" position when using the preheater, and the red indicator light should be on. Start the engine after 20 seconds, and start fluid can also be used without metering equipment. After the engine starts, it should be "warmed up" for more than 5 minutes without load (the winter time should be longer) to make the oil temperature rise to the working range before starting to drive.

Before starting, step on the brake pedal and release the brake lever.

Bulldozer 1When starting with a hand crank, it is necessary to put all five fingers together. When starting with a pull rope, do not wrap the rope around your hands.

2.When the bulldozer uses a wire rope to pull a heavy load, there must be no one nearby. 3.

Push the soil to the slope, the blade must not exceed the slope edge, and only after changing the reverse can the blade be lifted and reversed. 4.The bulldozer shall not exceed 35 ° on the uphill and downhill, and the cross-slope shall not exceed 10

The throttle of the bulldozer is reversed, that is, the throttle is the slack throttle, the slack throttle is the positive throttle, and the engine starts (the throttle is pressed). When you get to first gear, slowly release your foot on the throttle and the bulldozer will move forward, press the throttle and the dozer will stop.

During start-up: The user should never pull directly from the neutral position to the second or third gear, so as to avoid the second-hand bulldozer starting speed is too high, which will cause the transmission element to be subjected to excessive shock load.

Do not pull the throttle stick to the maximum throttle position before shifting gears. Each lever disc must be moved in an accurate and thorough position, and not stopped, so as not to slip the clutch friction disc, which can cause severe burns and wear.

Bulldozers are mainly suitable for shallow excavation and transportation of one to three types of soil, such as site cleaning or leveling, construction with small excavation depth and backfill volume, and small subgrade height.

Using remote control to operate the bulldozer, foreign technology has matured to such an extent.

1. Look at or feel the up and down changes of the front of the car, the front of the car is slightly winged up to lower the shovel blade of Xiweishan, and the front of the car is inclined down to lift the shovel a little;

2. The range of lifting or lowering of the shovel blade should be small, and the handle of the shovel blade should not be pulled too violently;

3. Push a shovel of relatively flat foundation first, and push along this flat foundation;

4. Use the high-frequency and low-amplitude shovel blade "shaking" action to improve, keep shaking and shaking the mountain spring when holding the hydraulic handle in the hand, and the shaking action is suitable for opening with 2 gears;

5. The combination of people and vehicles into one, that is to say, the whole time is fully dedicated.
