Technical Field

[0001] The utility model relates to the technical field of excavator buckets, in particular to a wear-resistant excavator bucket. Background Art

[0002] Excavators, also known as digging machines, are often used in engineering projects to level sites, dig foundations, etc. In the prior art, an excavator bucket includes a bucket and shovel teeth. Since excavators are often used to dig soil and rocks, long-term frictional contact with soil and rocks causes the side walls and bottom of the bucket to be easily damaged, and the shovel teeth often contact hard objects and cause damage. Due to the working scene of the excavator bucket, the excavator bucket has a high loss rate and high use cost. Utility Model Content

[0003] The utility model aims to provide a wear-resistant excavator bucket to solve the problems of high loss rate and high use cost of the excavator bucket proposed in the above background technology.

[0005] Preferably, the side panels are retracted inwards near the bucket mouth, and the retraction angle is set at 4°-7°.

[0006] Preferably, a shovel tooth protection cover is provided on the shovel tooth, the fixing device includes a threaded rod, a threaded groove is provided on the side of the shovel tooth, a through hole is provided at a corresponding position on the side of the shovel tooth protection cover, and the threaded rod passes through the through hole and is threadedly connected to the threaded groove.

[0007] Preferably, the side blade is installed near the bucket mouth, the side blade is turned outward, and the side blade is connected to the side plate through bolt threads.

[0008] Preferably, the side plate is provided with a threaded notch, the side baffle is provided with a bolt, so that the side baffle is threadedly connected and fixed to the side plate, and the surface of the side baffle is provided with two guide grooves.

[0009] Preferably, the bottom baffle is provided with a mud groove, the bottom baffle is provided with a through countersunk hole, the bottom plate is provided with a through hole at a corresponding position, the mud guard strip is provided with a threaded notch at a position corresponding to the through hole, and the bottom baffle and the mud guard are fixed by threaded connection with bolts.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The use of the tooth protection cover reduces the contact between the tooth and the excavated material, reduces the friction on the tooth, and the tooth protection cover is replaceable, which reduces the wear of the tooth. The side plate is retracted to make the bucket mouth smaller. The position and size of the bucket mouth limit the entry of the excavated material during excavation, and the tooth makes the excavated material more fluffy. After entering the bucket, the excavated material spreads out, avoiding direct friction between the excavated material and the inner wall of the bucket side plate.

[0012] 2. The side baffle fixed by bolts isolates the friction between the excavated object and the side outer wall, thus increasing the service life. The side blades installed on the side baffle enable the excavator bucket to destroy the structure of the excavated object to a greater extent during use, making the excavated object more fluffy. The side baffle is guided by the guide groove on the side baffle, which reduces the friction on the side baffle and increases its service life.

[0013] 3. Under the action of the shovel teeth, the excavated objects become fluffy, and the mud grooves of the bottom baffle make the bottom surface uneven, which prevents the excavated objects from being compressed twice during the excavation operation. The design of the mud grooves allows a part of the excavated objects to adhere, reducing the friction between the excavated objects and the bottom baffle. The mud guard strips prevent the excavated objects from directly contacting the bucket, and the protruding parts can make the excavated objects further fluffy when entering the bucket, thereby increasing their service life.
