Crushing and hammering bauxite by excavator

1.

When using the breaking hammer, first of all, we should use the breaking mode, then use the hammer head close to the ground, step by step, and use its own impact force to make the breaking hammer slowly go deep. When the hydraulic hammer is working, the drill rod must be pressed on the rock, and a certain pressure must be maintained before the hammer is started. It is not allowed to start in the suspended state

if the breaking hammer can't break away from the broken object, don't move the excavator arm left and right. If it's easy to break the hammer tip, it can only move up and down. If it still can't, continue to break and move up and down. If it still can't, it can only move left and right a little, and continue to move up and down until it is removed

The most important characteristics of breaking hammer are its striking force and impact energy. Each type of hALB hammer has a strong impact power system of "hydraulic + nitrogen". The system has the advantages of high efficiency, minimum energy loss and maximum impact energy, which can be provided by the hammer

< H2 > extended data

usage of hydraulic hammer:

1) read the operation manual of hydraulic hammer carefully to prevent damage to hydraulic hammer and excavator, and operate them effectively

Before operation, check whether the bolt and connector are loose, and whether the hydraulic pipeline has leakage

Do not use hydraulic hammer to peck holes in hard rock

It is not allowed to operate the hammer when the piston rod of the hydraulic cylinder is fully extended or retracted

When the hydraulic hose vibrates violently, stop the operation of the hammer and check the pressure of the accumulator

6) to prevent the interference between the boom of the excavator and the bit of the breaking hammer

Do not immerse the hammer in water except the drill bit

The hammer should not be used as a lifting device

It is not allowed to operate the hammer on the crawler side of the excavator

10) when the hydraulic hammer is installed and connected with the hydraulic excavator or other construction machinery, the working pressure and flow of the hydraulic system of the main engine must meet the requirements of the technical parameters of the hydraulic hammer. The "P" port of the hydraulic hammer is connected with the high-pressure oil circuit of the main engine, and the "a" port is connected with the oil return circuit of the main engine

2. It's normal.
I feel like this at the beginning.
the key is to keep the angle of the crank arm.
make sure that the drill bit is perpendicular to the working face

3. It's called breaking hammer. It's installed in the position of the bucket after unloading the bucket

the breaking hammer needs to be customized, and the manufacturer who sells the breaking hammer will be responsible for the installation

4. The most important thing is the hydraulic pump and the counterweight damage of the whole vehicle. The main reason is whether you have a crushing project. You can buy a large amount of work. After all, the excavator is a profitable machine. Otherwise, crushing is more expensive than digging. If you just bought a excavator that is hundreds of thousands larger, it is recommended not to install it. When you come back with the capital, the body of the excavator drops a lot. It is recommended to install crushing after 1.2 years hammer

5. 1. The crushing hammer should strike vertically as far as possible, without empty gun
2. Stop for a few seconds after 15-20 seconds to extend the service life of the hammer< 3. Beat butter frequently

6.

The shell of the breaking hammer of the excavator completely encloses the hammer body, and the shell is provided with damping material, which can proce buffer between the hammer body and the shell of the breaking hammer and rece the vibration of the carrier at the same time

the box type hydraulic breaking hammer can provide better protection for the hammer body, rece the vibration of the carrier, and solve the problem of loose shell at the same time. As a general user, we should choose the most suitable hydraulic hammer according to the comprehensive consideration of many aspects

extended data

excavator related parameters:

1, excavation force

for excavation force, excavation force is mainly divided into jib excavation force and bucket excavation force

the action point of the two digging forces is the tooth root of the bucket (the lip of the bucket), but the power is different, and the digging force of the jib comes from the jib cylinder; The digging force of the bucket comes from the bucket cylinder

2, grounding pressure

the ground conditions of excavator are determined by the grounding pressure

3. Track shoes

· it is very important to install suitable track shoes on the machine. For crawler excavators, the selection criteria of crawler are: as long as possible, try to use the narrowest crawler shoes

4, walking speed

for crawler excavator, walking time accounts for about one tenth of the whole working time. Generally speaking, two speed excavator can meet the walking performance

7. There are many models. For example, 210 can be installed with 135 hammers or 140 hammers. If you are not afraid of damaging the car, you can also press 150 to guarantee that the car will be scrapped in one year. If you have 270 hammers, you can also press 135 hammers. In short, small hammers can't be used for small cars, but they can't be used for small brands and models

8. Is nitrogen added to the hammer?

9. It's true. The physical injury of occupational hazards includes vibration injury
risk factors

physical factors
(1) occupational diseases possibly caused by high temperature

: heatstroke

(2) occupational diseases possibly caused by high pressure

: decompression diseases

(3) occupational diseases possibly caused by low pressure

: altitude diseases (4) occupational disease that may be caused by local vibration: arm vibration disease
in addition, st may also cause silicosis.

10. It is preliminarily estimated that the oil temperature increases and the viscosity of hydraulic oil decreases e to the long service time, which leads to the increase of oil leakage; If there is no problem with the hydraulic oil, it is the internal wear of the hammer, or the seal is damaged; If there is a comparison, take a look at the temperature of the crushing hammer of another normal machine.
