Detailed Description

The utility model is further described below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.

As shown in fig. 1, the bucket connecting structure of the present utility model comprises a first connecting shaft 2a, a second connecting shaft 2b, a third connecting shaft 2c and a fourth connecting shaft 2d provided on a bucket connecting surface, wherein the first connecting shaft 2a is parallel to the third connecting shaft 2c, the second connecting shaft 2b is parallel to the fourth connecting shaft 2d, and the first connecting shaft 2a and the third connecting shaft 2c are perpendicular to the second connecting shaft 2b and the fourth connecting shaft 2 d; under the working condition of the excavator, the first connecting shaft 2a and the third connecting shaft 2c are connected with the movable arm of the excavator, so that the requirement of the working condition of the excavator is met; when the working condition of the excavator is converted into the working condition of the flat ground, the bucket is turned for 90 degrees, the second connecting shaft 2b and the fourth connecting shaft 2d are connected with the movable arm, and the working condition requirement of the excavator on the flat ground is met. The first connecting shaft 2a, the second connecting shaft 2b, the third connecting shaft 2c and the fourth connecting shaft 2d are preferably distributed in a rectangular shape, and are compact in structure and convenient to turn.

One end of the first connecting shaft 2a, the second connecting shaft 2b, the third connecting shaft 2c and the fourth connecting shaft 2d is mounted on the bucket connecting surface through a first mounting plate 1, and the other end is mounted on the bucket connecting surface through a second mounting plate 3. The first connecting shaft 2a, the second connecting shaft 2b, the third connecting shaft 2c and the fourth connecting shaft 2d are connected with the first mounting plate 1 and the second mounting plate 3 and the first mounting plate 1, the second mounting plate 3 and the bucket in a welding mode, so that the structure is firm, and the use requirement of the excavator is met.

As shown in fig. 2, the arm 4 of the excavator boom is provided with jaws for connecting the first connecting shaft 2a and the third connecting shaft 2c or the second connecting shaft 2b and the fourth connecting shaft 2d, and the jaws are preferably provided in two positions corresponding to the connecting shafts, including the first jaw 4a and the second jaw 4b.

As shown in fig. 3, the first jaw 4a and the second jaw 4b of the arm 4 of the excavator boom are connected to the first connecting shaft 2a and the third connecting shaft 2c in fig. 1, and an excavating operation is performed. When the leveling operation is needed, a driver controls the movable arm and the bucket rod in the cab, the first claw 4a and the second claw 4b of the bucket rod are connected with the second connecting shaft 2b and the fourth connecting shaft 2d in fig. 1, the operation state is as shown in fig. 4, the leveling operation can be realized after the bucket level is adjusted, the operation is simple, the efficiency is high, and the leveling effect is outstanding.
