The terminal of the most widely used working device used in excavator excavator is also the working part that the excavator bears the maximum load during the mining operation, and a excavator takes 4-5 shovels during the average 8 years of life, so the excavator dug belongs to the consumable accessories, especially in the construction environment of the stone square, the wear speed of the excavator bucket. Especially fast. When the bucket is worn to a certain extent, the digging bucket can be reinforced in time, and its service life can be effectively improved. However, it is observed by the small editor that most excavator users have blind areas to reinforce the dug. It is often just a random welding of a large number of various steel plates, so the blind reinforcement of the bucket is more harmful to the excavator itself than the advantages of the excavator. Next, let's talk about digging and reinforcing these things together.
Attentions of excavator dug
It is prudent to blindly excavate the excavator bucket.
Most of the excavator users think that the thicker the excavator dug is, the longer it lives, so when the dug needs to be strengthened, a large amount of steel is welded on the bucket, and a thick armor is put on the bucket. Xiaobian does not deny that this practice will greatly prolong the life of the bucket, but do you consider the feeling of the excavator itself in doing these work?
As we all know, the technology of the excavator has been developed for more than 100 years. The shovel technology of the excavator has been mature, and every excavator designed by the engineers has applied the stress perfectly. In the case of no excessive wear, a wide range of welded stiffeners will only destroy the stress of the bucket itself, make the digging resistance increase, and sometimes accelerate the wear and tear of the bucket. Second, if the dug is protected in all directions, it will increase the weight of the dug per bucket. The heavy bucket not only increases the fuel consumption of the machine, but also has a considerable impact on the life of the machine under the high load condition. Therefore, if the dug bucket has more serious wear and tear, there should be a proper strengthening of the pertinent department. Where the wear is more serious, it should be strengthened, and it is really impossible to replace the new fight.
The following points should be paid attention to the reinforcement of the excavator bucket
First of all, we must pay attention to two key problems in reinforcing the bucket, one is firm and the other two is effective. First, it is necessary to find a better welding worker. If the welding process is not in place, the quality of the dug bucket will be greatly affected, the life of the dug bucket will be affected, the empty mouth is empty, we have the truth!
Secondly, do not blindly put heavy armor on the bucket, resulting in lower efficiency and higher fuel consumption. The experts have done a study: the weight of the bucket is increased by 0.5 tons, the cycle cycle increases by 10%, and the annual gross profit is reduced by 15%, so the part of the welding which needs to be strengthened is not the whole welding.
Experience sharing of excavator shovel reinforcement
In general, the edges of the dug bucket, the floor, the side board and the tooth root are the most worn places. So, to observe the wear degree of these places regularly, it is necessary to strengthen the treatment of these places under the necessary circumstances.
Root reinforcement: the strengthening of the tooth root installation board is very necessary. In the daily work, the excavator is not well strengthened, and the tooth root will have severe wear and tear, and the bucket teeth are not installed for a long time. There are two options for reinforcement here. One is reinforcement, the other is a wear-resistant block. It is important to note that the practice of strengthening the reinforcement is simple and economical, but the weld must not be welded with the weld of the root in welding, which will affect the strength of the tooth root welding.
Excavator dug edge plate reinforcement
Side plate and side reinforcement: the severe wear of the side plate will reduce the effective bucket capacity of the bucket and affect productivity. At the same time, the edge knife also helps to cut into the material and protect the side plate, so the excavator needs to install the edge knife. Because the side is not a high wear area, the strengthening of the side is not too strong, so as not to affect the overall weight of the bucket.
Floor reinforcement: the floor is a serious area of wear and tear, and it is necessary to strengthen the floor. The stiffeners of the floor should choose hard and wearable long plate as raw materials. It is necessary to protect the overall shape of the bucket, so as to avoid the impact on the angle of penetration and influence the productivity. Many customers choose discarded chain plates as reinforcing materials, and the individual thinks it is good. It needs to be noted that the welding of reinforcement should be welded along the direction of the welding of the original stiffeners and superposed on the two plates.
Good operating habits can also prolong the life of the dug
We take excavating for example, excavating is the most important work of excavator, and the driving excavator also has a lot of skills, which can directly affect the efficiency of the work. When excavating the soil, the bucket cylinder should be the main part and the oil cylinder of the boom should be subsidiary. The angle of the bucket teeth should be adjusted according to the trajectory of the bucket. The bucket teeth must be inserted into the soil like a knife and cut into vegetables instead of "pat" into the soil. When inserted to a certain depth, finish the hook and raise the arm. It's a perfect excavating action.
To sum up, to reinforce the bucket must master the correct method, good steel used, do not arbitrarily weld reinforcement plate, otherwise it will be too late. Some matters needing attention in digging bucket are introduced here, hoping to have some reference meaning for everyone.
