Description

Excavator bucket with protection structure Technical Field The utility model belongs to the technical field of excavators, and particularly relates to an excavator bucket with a protection structure. Background The excavator bucket is also called as an excavator bucket and is an important working device of an excavator and is used for excavating materials such as soil, rocks, gravel and the like, and the excavator bucket is composed of a tooth base plate, a bottom plate, a side plate, a wall plate, a hanging plate, a back plate, an ear sleeve, bucket teeth, a tooth base, a guard plate or bucket corners and other parts. Welding is the most critical manufacturing process of the bucket, and the welding quality directly influences the structural strength and the service life of the bucket. The manufacturing process of the excavator bucket comprises the processes of blanking, turning, milling, drilling, forming, welding, polishing, sand blasting, spraying and the like. The bucket belongs to a special industry equipment structure accessory, and can be manufactured with high efficiency and high quality by using special processing and manufacturing equipment such as a numerical control plasma cutting machine, a groove edge milling machine, a veneer reeling machine, a welding positioner, a boring machine and the like. In the conventional excavator working scene, when the excavator swings a powerful mechanical arm to perform excavating work, the bucket is used as a key component directly contacting with soil, and huge pressure and friction force are born. During the digging process, various sharp stones are often mixed in the soil, and the stones have different sizes and shapes and are hard in texture. These sharp stones act like sharp edges constantly scraping and stroking the surface of the bucket as it cuts into the earth. With the continuous operation of the excavator, the contact frequency of the bucket with soil and stones is extremely high, scratches can be deeper during each digging, fine scratches gradually accumulate and deepen, and finally obvious ravines can be formed. More seriously, these increasingly deeper scratches can make the metallic structure of the bucket surface increasingly fragile, as the bucket is subjected to significant impact forces and vibrations during excavation. Under the action of continuous stress, the metal fatigue degree at the scratch is continuously increased, and finally cracks are most likely to be generated. Once the bucket is cracked, the normal working efficiency of the excavator can be affected, the service life of the bucket is reduced, potential safety hazards can be brought, such as sudden fracture of the bucket in the excavating process, and threat is caused to operators of the excavator and surrounding environments. Disclosure of utility model The utility model aims to provide an excavator bucket with a protective structure, and aims to solve the problems that various sharp stones are often mixed in soil to continuously scrape and scratch on the surface of the bucket in the existing excavator operation scene in the prior art, the contact frequency of the bucket with the soil and the stones is extremely high along with continuous work of the excavator, obvious ravines are generated on the surface of the bucket, and the metal structure of the surface of the bucket is gradually weakened due to the continuously deepened scratches. Under the action of continuous stress, the metal fatigue degree at the scratch is continuously increased, and finally cracks are most likely to be generated. Once the bucket is cracked, the normal working efficiency of the excavator can be affected, the service life of the bucket is reduced, potential safety hazards can be brought, and the problems of threat to operators and surrounding environments of the excavator are caused if the bucket is broken suddenly in the excavating process. The excavator bucket with the protection structure comprises a bucket main body, bucket ears, tooth holders and tooth tips, wherein the bucket ears are connected to the upper surface of the bucket main body, an assembly component is arranged between the bucket main body and the tooth holders, and the end parts of the tooth holders are connected with the tooth tips; The scraper bowl main part's lower surface is connected with the slide rail, the lower surface of scraper bowl main part is connected with the screw thread post, the lower surface of scraper bowl main part is provided with the row stone spare, is close to the slide rail row stone spare upper surface has seted up the guide way, is close to the screw thread post row stone spare surface has seted up the strip type groove, the screwed pipe has been cup jointed on the surface of screw thread post. Preferably, the excavator bucket with the protection structure is characterized in that three groups of sliding rails and the guide grooves are arranged, and the stone discharging piece is in sliding connection wit
