Description

Technical Field

[0001] The utility model relates to the technical field of buckets, and specifically discloses a bucket. Background Art

[0002] A bucket is an important accessory on construction machinery such as loaders, excavators, bulldozers, etc., and is usually installed at the front end of the equipment or on the robotic arm. It is used for excavating, loading, transporting, and unloading materials such as soil, stones, gravel, coal, ore, etc. The bucket has an open top for loading materials and a closed bottom for keeping the materials from scattering during transportation. Bucket teeth are provided at the edge of the bucket to facilitate cutting into the materials more easily. The bottom of the bucket includes a bent portion, and flat portions are provided at both ends of the bent portion, and bucket teeth are provided on one of the flat portions.

[0003] During the working process of the excavator, both the bottom of the bucket and the inner side wall of the bucket will be subject to great friction, which easily reduces the service life of the bucket. The existing metal wear-resistant plate structure for the bottom of the bucket and the inner wall of the bucket uses a whole rectangular parallelepiped metal wear-resistant plate, and the metal wear-resistant plate is fillet welded to the arc plate. Such a metal wear-resistant plate can basically ensure the stiffness and wear resistance of the bucket.

[0004] However, the welding setting of the whole metal wear-resistant plate results in a long welding repair cycle, great difficulty in gas cutting the plate, large welding workload, and inconvenient maintenance. Content of the Utility Model

[0005] In view of the above deficiencies of the prior art, the utility model provides a bucket to solve the problems of long welding repair cycle, great difficulty in gas cutting the plate, large welding workload, and inconvenient maintenance caused by the welded metal wear-resistant plate.

[0006] To achieve the above object, the technical solution of the utility model is as follows:

[0007] A bucket includes a back plate, side plates are provided at both ends of the back plate, a bucket tooth mounting plate is provided at one end of the back plate, bucket teeth are provided on the bucket tooth mounting plate, and a metal wear-resistant plate is detachably provided on the inner side wall of the back plate; the metal wear-resistant plate includes a plurality of bottom bent plates and bottom straight plates. The detachably provided metal wear-resistant plate is convenient for disassembly and assembly, shortens the maintenance and replacement time, and reduces the labor intensity. The setting of the bottom bent plates and bottom straight plates is convenient for covering the inner side wall of the back plate and reducing the wear on the back plate.

[0008] Preferably, the bottom bent plates are arranged on the curved surface portion of the back plate; the bottom straight plates are arranged on the flat surface portion of the back plate and are close to one end of the bucket tooth mounting plate. This ensures covering the more worn parts on the inner side wall of the back plate and prolongs the service life of the back plate.

[0009] Preferably, a plurality of countersunk holes are provided on the bottom bent plate; a plurality of countersunk holes are provided on the bottom straight plate; bolts are provided in the countersunk holes; the bolts are threadedly arranged on the back plate. The detachable setting of the metal wear-resistant plate is completed. The setting of the countersunk holes reduces the wear of the bolt heads and ensures the firm setting of the metal wear-resistant plate.

[0010] Preferably, the bottom bent plate is integrally arranged in an arc-shaped plate shape; the bottom straight plate is integrally arranged in a rectangular plate shape. Ensure that the bottom bent plate can cover the inner side of the curved surface part of the back plate, and ensure that the bottom straight plate can cover the flat surface part of the back plate.

[0011] Preferably, a supporting bottom plate is provided on the outer wall of the back plate; the supporting bottom plate is arranged at an angle with the flat surface part of the back plate; one end of the supporting bottom plate is fixedly arranged on the outer wall of the back plate, and the other end is fixedly arranged on the support plate; the support plate is fixedly arranged on the outer wall of the curved surface part of the back plate. The setting of the supporting bottom plate can reduce the wear of the outer wall of the flat surface part of the back plate and extend the service life.

[0012] Preferably, the metal wear-resistant plate is a manganese steel plate; a wear-resistant layer is surfacing-welded on the upper surface of the metal wear-resistant plate; the wear-resistant layer is a high Cr high Mo alloy. It has better wear resistance and a longer service life.

[0013] Preferably, a crescent plate is provided on the side plate through bolts. The setting of the crescent plate can cut the excavation object and improve the excavation performance.

[0014] The beneficial effects of the present utility model are as follows: The detachable metal wear-resistant plate is convenient for disassembly and assembly, shortens the maintenance and replacement time, and reduces the labor intensity. The settings of the bottom bent plate and the bottom straight plate facilitate covering the inner side wall of the back plate and reduce the wear on the back plate. BRIEF DESCRIPTION OF THE DRAWINGS
