Technical Field
[0001] The utility model relates to the technical field of excavator buckets, in particular to an excavator bucket structure used for clearing soil in a foundation pit. Background Art
[0002] An excavator, also known as a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and load them into a transport vehicle or unload them to a stockpile. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loose soil and rock. From the development of engineering machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important engineering machinery in engineering construction. The three most important parameters of an excavator are operating weight (mass), engine power, and bucket capacity. The bucket refers to the bucket installed on the excavator, also called a digging bucket. According to the working mode, it is divided into a backhoe bucket and a front shovel bucket. The backhoe bucket is generally used. The bucket is a structural product, which is composed of a tooth seat plate, a bottom plate, a side plate, a wall plate, a hanging ear plate, a back plate, a bucket ear plate, a bucket ear sleeve, bucket teeth, a tooth seat, a guard plate or a bucket angle and other parts and components, so welding is the most critical manufacturing process of the bucket, and the welding quality directly affects the structural strength and service life of the bucket.
[0003] The bucket of the excavator is installed during excavation for excavation of foundation pits. After the excavation of the foundation pit is completed, the tool plate cannot contact the ground of the foundation pit due to the bucket teeth, so that the soil remaining on the bottom of the foundation pit needs to be cleaned manually. If mechanical cleaning is required, the driver needs to replace the bucket again, which is a cumbersome and time-consuming process. When the excavator is excavating the foundation pit, the soil at the bottom of the foundation pit is relatively humid, resulting in high soil viscosity and arbitrary adhesion in the bucket, affecting the capacity of the bucket and needing to be cleared, but manual cleaning is time-consuming and inefficient.

[0030] Working principle: When the driver is excavating the foundation pit, he needs to remove the bucket moving shaft 4 and the bucket receiving shaft 5 of the bucket moving seat 2 and the bucket receiving seat 3, move the excavator's arm to the position of the bucket moving seat 2 and the bucket receiving seat 3, and then install the bucket moving shaft 4 and the bucket receiving shaft 5 at the position of the bucket moving seat 2 and the bucket receiving seat 3 and fix them. The driver operates the excavator to excavate the foundation pit. During the early excavation, the soil cleaning chain 21 is untied from the soil cleaning ring 22. When the foundation pit is dug to the lower layer, the soil has high moisture and high viscosity. At this time, the sticky soil will adhere to the excavator bucket 1. The soil cleaning chain 21 is installed on the excavator bucket 1 through the connecting buckle 23. When the excavator bucket 1 is shoveling mud, the loose soil cleaning chain 21 can prevent the soil from fitting too tightly to the inner wall of the excavator bucket 1. Some gaps are left in between to avoid vacuum formation inside. When the excavator bucket 1 throws mud, the negative pressure is destroyed by the gap in the middle, and the mud can easily fall off the bucket wall. After the foundation pit is basically excavated and formed, the residual soil at the bottom of the foundation pit needs to be cleaned. At this time, the fixing bolts 26 and fixing nuts 27 of the fixing blocks 24 on the excavator bucket 1 and the bucket frame 7 are removed, and the telescopic inner rod 16 is retracted into the telescopic outer column 17, and the bucket frame 7 is raised to expose the tool plate of the excavator bucket 1, so that the excavator can clean the residual soil at the bottom of the foundation pit. After the cleaning is completed, the telescopic inner rod 16 extends toward and from the telescopic outer column 17, the bucket frame 7 is lowered, and the bucket tooth frame 8 of the bucket frame 7 is combined with the tool plate of the excavator bucket 1. After the fixing bolts 26 and fixing nuts 27 on the fixing block 24 are reinstalled and tightened, the excavator bucket 1 will not be affected from carrying out other earthwork construction.
