装载机铲斗的磨损形式
来源：/ 日期：2023-05-20
在大多数情况下，装载机配装的工作机具是铲斗，用于铲掘及转运物料。装载机铲斗，作为直接接触工作物料的工作机具，是装载机的主要磨损件之一，直接关系到使用成本。那么装载机铲斗的磨损形式有哪些？下面济南装载机租赁厂家为您分析：
In most cases, the work tool equipped with the loader is the bucket, which is used for digging and transporting materials. The loader bucket, as a working tool that directly contacts working materials, is one of the main wear parts of the loader and directly affects the cost of use. So what are the forms of wear and tear on the loader bucket? Below is an analysis by the rental manufacturer of Jinan loaders for you:
铲斗磨损形式及原因分析
Analysis of the forms and causes of bucket wear
装载机铲斗容积较大，一般采取铲斗下体前端焊接耐磨材料制作的铲刀板（如16Mn等材料），铲斗两侧安装边护板，然后在铲刀板上等间距安装斗齿，斗齿与铲刀板的连接方式为螺栓连接。
The bucket volume of a loader is relatively large. Generally, a blade plate made of wear-resistant materials welded to the front end of the lower body of the bucket (such as 16Mn) is used. Edge protection plates are installed on both sides of the bucket, and then bucket teeth are installed at equal intervals on the blade plate. The connection between the bucket teeth and the blade plate is bolted.
铲刀板磨损
Blade wear
铲刀板磨损严重，表现在厚度变薄，位于斗齿之间的铲刀板由原来的直线型逐渐成为向内弯曲的弧线型。
The blade plate is severely worn, manifested by thinning in thickness, and the blade plate located between the bucket teeth gradually changes from a straight line to an inward curved arc.
刀板

（1）铲刀板磨损后，由于其厚度减少，当更换斗齿时，斗齿后端上下部分与铲刀板之间存在的间隙较大，两者之间仅依靠斗齿螺栓进行固定，则装载机工作一段时间后，由于斗齿频繁承受物料的冲击，导致斗齿固定螺栓松动，进而造成斗齿及铲刀板磨损加剧，终导致铲斗无法正常使用。
(1) After the blade plate is worn out, due to its reduced thickness, when replacing the bucket teeth, there is a large gap between the upper and lower parts of the rear end of the bucket teeth and the blade plate. Only the bucket tooth bolts are used to fix the gap between the two. After the loader works for a period of time, due to the frequent impact of materials on the bucket teeth, the bucket tooth fixing bolts become loose, resulting in increased wear of the bucket teeth and blade plate, ultimately leading to the inability of the bucket to function properly.
（2）铲刀板更换不及时，容易造成铲斗的母体（下端）过度磨损，同时降低了铲斗的整体刚度，极易造成铲斗受力变形，并严重影响了使用寿命。
(2) If the blade is not replaced in a timely manner, it is easy to cause excessive wear on the mother body (lower end) of the bucket, while reducing the overall stiffness of the bucket, which can easily cause force deformation of the bucket and seriously affect its service life.
斗齿磨损
Bucket teeth wear
斗齿在铲装作业中起着“开路先锋”的作用，磨损速度快，因而更换频繁。磨损的形式为长度变短，厚度变薄，甚上下两部分分离。
Bucket teeth play a pioneering role in shovel loading operations, with fast wear and frequent replacement. The form of wear is shortening in length, thinning in thickness, and even separating the upper and lower parts.

（1）斗齿的固定螺栓松动后，驾驶员未能及时进行固定，造成斗齿螺栓与斗齿及铲刀板之间的配合间隙越来越大，有可能造成固定螺栓折断或者斗齿损坏，增加铲刀板的磨损。
(1) After the fixing bolts of the bucket teeth become loose, the driver fails to fix them in a timely manner, resulting in an increasing fit gap between the bucket teeth bolts and the bucket teeth and blade plate. This may cause the fixing bolts to break or the bucket teeth to be damaged, increasing the wear of the blade plate.
（2）由于斗齿缺损或者过度磨损后未及时进行更换，造成铲刀板过度磨损，进而造成铲刀板因早期损坏而提前报废，降低了铲斗的使用寿命。
(2) Due to the lack or excessive wear of the bucket teeth and failure to replace them in a timely manner, the blade plate is excessively worn, resulting in early scrapping of the blade plate due to early damage, reducing the service life of the bucket.
It can be seen that it is very important to understand the wear forms and causes of the bucket, and to carry out reasonable maintenance and repair to extend its service life. If there are any other matters, please come to our website Consult!
