It is suitable for grabbing steel pipes or cylinders.

15. a shell bucket.

Loader driver and excavator driver recruitment and job search are all in the [Hunting Driver] market.

In the same way, it is necessary to pay attention to the pressure of the excavator control accessory valve; The weight of the hammer should be equivalent to the weight of the bucket + full bucket soil, which affects the stability of the whole machine.

The pressurized oil provided by the pumping station of the excavator or loader can be used to remove the soil from floating rocks and rock crevices more effectively in the excavation of building foundations. The principle of selecting a hydraulic breaker is to choose the most suitable hydraulic breaker according to the excavator model and operating environment.

Hello, it's best not to hit diagonally, when using the breaker, you should first use the crushing mode, and then use the hammer head to stick to the ground, step by step, using its own impact force to let the breaker go deeper slowly. When the hydraulic breaker works, the drill rod must be pressed on the rock first, and a certain pressure must be maintained before the breaker is started, and it is not allowed to start in the suspended state. If the breaker can not be separated from the crushed, do not move the excavator left and right to crack the mountain arm, so that it is easy to break the tip of the hammer, can only move up and down, if it still does not work, continue to crush, move up and down, if it still does not work, can only move slightly left and right, continue to move up and down until it is removed.

The most important characteristics of a breaker are its striking force and impact energy. Each model of the HALB breaker has a powerful impact power system of "hydraulic + nitrogen". The source and system has high efficiency, minimizes energy loss and maximizes impact energy, and the breaker can provide powerful impact energy.

<> the relationship between the area A1 acting on the upper cavity of the cylinder block and the area A2 acting on the oil pressure of the lower cavity of the cylinder block is A1>A2, and A2 is always under high pressure. When A1 changes from high pressure to low pressure, the piston moves upward, accompanied by high-pressure nitrogen pressure storage in the rear cylinder. The initial situation of the piston upward:

Both the piston and the valve are in their lower position. The upper cavity of the cylinder block is subjected to low pressure, and the lower cavity of the cylinder block and the high-pressure chamber of the valve are always subjected to high pressure at all times. The low-pressure chamber connected to the return port is always at low pressure.

The low-pressure cavity is connected with the cylinder block conversion cavity, and the A5 connected with the cylinder block conversion cavity is subject to low pressure, so the cylinder block conversion cavity is subjected to low pressure before the piston moves upward. Because the area A3 and A4 are subject to high pressure (A3 A4), the valve is subjected to downward force before A5 is subjected to high pressure. High-pressure oil enters the lower cavity of the cylinder block and raises the piston.

When the piston begins to move upwards, the oil pressure of the piston conversion chamber does not change. When the piston moves upwards, the high-pressure nitrogen is pressurized. When the piston moves to the middle of the valve, the cylinder body conversion cavity is connected to the lower chamber, so that the cylinder block conversion cavity is subjected to high pressure.

A3, A4 and A5 are all subject to high pressure, and their area relationship A4 + A5 > A3 is so that the valve is subjected to upward force, and the valve moves upward under the force, and when the piston stops moving, the high-pressure nitrogen energy storage reaches the maximum. When the piston is up, the piston conversion chamber is connected to the high-pressure chamber in the valve, so that the upper cavity of the cylinder block becomes subject to high pressure. Both the upper and lower chambers are subjected to high pressure, and A1 A2, the piston is subjected to downward force.

On the other hand, the high-pressure nitrogen pressure gives the piston a downward force, so that the piston moves rapidly downward. Before the valve goes down, the piston strikes the drill rod, and the cylinder pin body conversion chamber is connected to the low-pressure chamber, so that A5 is subjected to low pressure. A3 and A4 are subject to high pressure, A3 A4, so the valve moves downward.

The piston works when the valve moves downward, and the piston strikes the chisel. When the piston finishes striking the chisel, the piston begins to move upwards. The hammer repeats in turn - to get the job done.

The shell of the excavator breaker completely encloses the hammer body, and the shell is equipped with vibration damping material to create a cushion between the breaker hammer and the shell, and also reduce the vibration of the carrier.

The box-type hydraulic breaker can provide better protection for the hammer body, low noise, reduce the vibration of the carrier when working, and also solve the problem of loose shell. As a general user, it is necessary to choose the most suitable hydraulic breaker according to the comprehensive consideration of many aspects.

Excavator breaker is a type of equipment commonly used for rock crushing and demolition of buildings, but whether it can excavate iron ore depends on the specific situation. If the hardness and strength of the iron ore are high, the use of an excavator breaker for covert excavation may not be effective, and may even cause damage to the breaker. Therefore, before excavating iron ore, it is necessary to carry out detailed investigation and evaluation, and select the appropriate excavation equipment and process according to factors such as the hardness, strength and depth of iron ore.

In general, the most suitable equipment for iron ore excavation is a rotary drilling rig or blasting tool equipped with a rock drilling bit.

Hello friends, let me give you the answer that the excavator breaker is mainly used to crush and dismantle concrete structures, rocks or other hard materials, while iron ore is usually hard, so the use of breaker to mine iron ore is not effective. In contrast, the mining and handling of iron ore is often carried out using equipment such as loaders or loaders. If the iron ore is fragile and small in size, it may be considered to use a crushing hammer to crush, but this situation is not common in iron ore mining.

Qinqin is happy to answer for you, the excavator breaker hammer is mainly used to crush hard materials such as concrete and rock, while iron ore is an ore with relatively high hardness. Although the breaker can crush iron ore by hammering, it is very inefficient and can easily damage the breaker, so it is not recommended to use the breaker to mine iron ore. For the mining of iron ore, it is generally necessary to use a larger type of excavator or loader, and be equipped with corresponding mining equipment, such as mining crusher, screening machine, conveyor, etc., to improve mining efficiency.

In addition, the combined mining of iron ore also has a certain impact on the environment, and it is necessary to comply with the relevant regulations and regulations of environmental protection.
