Description

Technical Field

[0001] The utility model relates to the technical field of earthwork construction machinery and equipment, in particular to a reinforced loader bucket. Background Art

[0002] For construction machinery such as excavators and loaders, among them, the loader is mainly used for the bucket to shovel materials. There are the following technical problems when the bucket shovels materials:

[0003] (1) At present, there is no protective structure on both sides of the existing loader bucket. After the bucket shovels into the material pile, since most of the materials are particulate matter, the two sides of the bucket wear quickly under the friction of the materials. At the same time, there is vibration during the driving process of the loader. If the materials shoveled by the bucket are relatively full, the materials will fall from the bucket to the ground. Generally, the width of the bucket is the same as the width of the vehicle body. After the materials fall, the tires often press on the materials left on both sides of the bucket, causing wear of the tires, and at the same time, the materials cannot be used continuously after being crushed.

[0004] (2) When the bucket shovels into the material pile, the bottom of the bucket will contact the ground. In order to reduce the wear of the bottom of the bucket, several reinforced bending plates are arranged at the bottom to strengthen the bucket. It is necessary to weld the bending plates to the bottom of the bucket. There is an ear plate connected to the driving device on the back of the bucket, and the ear plate will extend to the bottom of the bucket. The steel plate of the ear plate will divide the bottom of the bucket into multiple areas. When welding the bending plates, the bending plates are perpendicular to the steel plate of the ear plate, and at the same time, the weld between the bending plates and the ear plate is small, and the welding difficulty is great.

[0005] (3) The ear plates arranged on the back of the bucket often only cover the arc-shaped area of the bucket, and a protective plate is welded at the end of the bucket opposite to the bucket teeth. There is a weld between the protective plate and the bucket, and there is a risk of cracking of the end weld. Summary of the Utility Model

[0028] The following combines with the accompanying drawings to illustrate the detailed implementation manners of this embodiment.

[0029] A reinforced loader bucket, referring to Figure 1 and Figure 2 , includes the first wear-resistant steel plate 1 inclinedly arranged on both side walls of the bucket. The second wear-resistant steel plate 2 is fixedly installed on the first wear-resistant steel plate 1. The bucket ear plate 4 is arranged on the back 3 of the bucket. The bending plates 5 are installed adjacent to both sides of the bucket ear plate 4. Grooves 6 are opened on both sides of the bending plate 5. The bevel chamfer 7 is arranged at the end of the groove 6 and on the side of the bending plate 5. The reinforcing ear plate 8 is arranged on one side of the bucket ear plate 4. The reinforcing ear plate 8 installed at the top of the back 3 of the bucket extends to the protective plate 9.

[0030] The first wear-resistant steel plate 1 includes the inclined base 11 fixedly installed on both side walls of the bucket. The surface of the inclined base 11 is covered and installed with the steel plate 12. The steel plate 12 covers the surface of the inclined base 11 to prevent the surface of the inclined base 11 from being worn.

[0031] The inclined base 11 is inclined outward along the width direction of the bucket, so that the materials spilled on the ground are pushed to both sides by the inclined base 11, thereby avoiding the roller from rolling over the spilled materials.

[0032] The second wear-resistant steel plate 2 is several rectangular steel plates 12. The several rectangular steel plates 12 are arranged and installed on the first wear-resistant steel plate 1. When being impacted from the outside, the rectangular steel plates 12 bear the impact and improve the overall strength.

[0033] The bent plate 5 includes a first bent plate 5 and a second bent plate 5. The first bent plate 5 and the second bent plate 5 are adjacently arranged on both sides of the bucket ear plate 4. The size of the first bent plate 5 is larger than that of the second bent plate 5. The first bent plate 5 and the second bent plate 5 extend to the back of the bucket 3, thereby connecting the back of the bucket 3 and the bottom of the bucket into a whole, thus improving the overall force-bearing of the bucket.

[0034] The groove 6 is a rectangular groove opened on both sides of the bent plate 5. The rectangular groove can provide a guiding function during the welding operation. During welding, the rectangular groove is convenient for forming a molten pool, and at the same time, the welding torch can be moved along the direction of the rectangular groove.

[0035] The inclined chamfer 7 is inclined at the end of the groove 6. The inclined chamfer 7 is inclined towards the ground. The setting of the inclined chamfer 7 shortens the distance between the bent plate 5 and the reinforcing ear plate 8, and the welding can be carried out without inserting the welding torch into the bent plate 5 during welding.

[0036] The reinforcing ear plate 8 includes a first arc segment 81 and a second arc segment 82. The first arc segment 81 is located on the back of the bucket 3. The second arc segment 82 is located at the connection between the protective plate 9 and the back of the bucket 3. The second arc segment 82 is used to improve the strength of the connection weld between the protective plate 9 and the back of the bucket 3. The first arc segment 81 and the second arc segment 82 are integrally and transitionally installed, and the first arc segment 81 and the second arc segment 82 are of an integral structure.

[0037] When materials spill from both sides of the bucket to the ground:

[0038] The first wear-resistant steel plate 1 and the second wear-resistant steel plate 2 welded on both sides of the bucket provide protection, improving the strength and wear resistance of the bucket. The inclined base 11 is inclined outward at a certain angle, and can push the materials left on both sides of the bucket outwards for a certain distance during the vehicle's travel, avoiding the tires from pressing on the materials left on both sides of the bucket, and protecting the materials and the tires.

[0039] Although the specific implementation manners of the present invention are described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
