    The excavator is widely used as the terminal of the working device in the use of excavators. It is also the working part of the excavator that bears a lot of load during the excavation operation. An excavator consumes 4-5 buckets in an average life of 8 years. , so the excavator bucket is a dry and consumable part, especially in the stone construction environment, the bucket wear rate is particularly fast. The bucket is worn to some extent.

    When the bucket is reinforced in time, its service life can be effectively improved. However, the editor observed that most excavator users have blind spots in the problem of bucket reinforcement, and they often just randomly weld a large number of various steel plates on it. As everyone knows, such blind reinforcement of the bucket is more than the excavator itself. Fortunately, it is still necessary to grasp the scientific reinforcement production method to strengthen the bucket. Next, let’s talk about the reinforcement of the bucket.

    Reinforced excavator buckets need to be operated cautiously and blindly

    Most excavator users believe that the thicker and stronger the excavator bucket is, the longer the service life will be. Therefore, when the bucket needs to be reinforced, a large amount of steel is attached to the whole body of the bucket, and a thick layer of steel is applied to the bucket. thick armor. The editor does not deny that this approach will greatly extend the service life of the bucket, but have you considered the feeling of the excavator itself when doing these tasks?

    We all know that the manufacturing technology of excavators has a history of more than 100 years of development. The technology of buckets equipped by manufacturers for excavators is very mature. Every bucket designed by engineers has applied stress theory. . In the case of no excessive wear of the bucket, the large-scale welding of the reinforcing plate will only destroy the stress theory of the bucket itself, which will increase the digging resistance, and sometimes accelerate the wear and tear of the bucket. Secondly, if the buckets are protected in multiple directions, the weight of each bucket is bound to increase. Heavy buckets will not only increase the fuel consumption of the machine, but also have a considerable impact on the life of the machine when working under high load conditions. Therefore, if there is serious wear and tear of the bucket, appropriate reinforcement should be carried out on the local area. Where the wear is more serious, it should be reinforced, and if it really fails, it should be replaced with a new bucket!

    Excavator bucket reinforcement should pay attention to the following points:

    First of all, the reinforcement of the bucket should pay attention to two key issues, one is firmness, and the other is effective. First of all, find a welder with better skills. If the welding process is not in place, the quality of the bucket will be greatly affected and the service life of the bucket will be affected. Secondly, don’t blindly put thick armor on the bucket, which will lead to lower efficiency and higher fuel consumption. Experts once did a study: for every 0.5 ton increase in the bucket weight, the cycle cycle increases by 10%, and the annual gross profit decreases by 15%, so welding is performed on the part that needs to be strengthened, not the overall welding.

    Excavator bucket reinforcement experience sharing

    Generally speaking, the side knives, bottom plates, side plates and tooth roots of the bucket are the places with relatively large wear, so to regularly observe the wear degree of these places, in some cases, these places should be strengthened. deal with.

    Reinforcement of the tooth root: The reinforcement of the tooth root mounting plate is very important. In the daily work of the excavator, due to the poor reinforcement, the tooth root will be severely worn, and the bucket teeth cannot be installed for a long time. There are two options for the reinforcement of the stem, one is to stick the reinforcing ribs, and the other is to pack the anti-rush block. It should be noted that the method of sticking the reinforcing rib is simple and economical, but when welding, be careful not to overlap the welding seam of the tooth root, which will affect the welding strength of the tooth root.

    Side plate and side reinforcement: The severe wear of the side plate will reduce the effective bucket capacity of the bucket and affect the productivity. At the same time, the side knife also has the effect of cutting into the material and protecting the side plate. Therefore, the bucket needs to be equipped with a side knife. Since the side is not a high-wear area, the reinforcement of the side should not be too strong, so as not to affect the overall weight of the bucket. .

    Reinforcement of the bottom plate: The bottom plate is an area with serious wear and tear, and it is also very important to strengthen the bottom plate. The reinforcing ribs of the bottom plate should be made of hard and wear-resistant long plates, and the overall shape of the bucket should be protected so as not to affect the cutting degree of the fish. affect productivity. Many customers choose discarded chain plates as reinforcement materials. Personally, I think they are more preferred. It is necessary to pay attention to the connection of the reinforcement ribs.

    Follow the welding direction of the original rib plate, and stitch welding on the two plates.

    Good operating habits can also extend bucket life

    Here we take the bucket as an example. Digging is the main job of an excavator. There are also many skills when driving an excavator, which can directly affect the efficiency of the work. When excavating soil, the stick cylinder is the main method, and the boom cylinder is supplemented. The angle of the bucket teeth should be adjusted according to the travel path of the stick. The bucket teeth should be “inserted” into the soil like a knife to cut vegetables, rather than “slapped” into the soil. When inserted to a certain depth, complete the hook and lift the arm. It is a complete digging action.

    To sum up, it is necessary to master the correct method to reinforce the bucket, and do not arbitrarily weld the reinforcement plate, otherwise it will be too much. Some precautions about the reinforcement of the bucket are introduced here first, hoping to be of reference significance for everyone.
