[0002] An excavator, also known as a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the surface of the machine and load them into a transport vehicle or unload them to a stockpile. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rocks. During the excavation process, it is often necessary to use the bucket to dig away stones and soil piles on the ground and to initially level the ground. Generally, the ground is made more flat and compact by swinging the bucket and hitting it downward.

[0033] The control component 23 includes a fixing frame 24 fixedly mounted on the upper side of the fixing frame 10, the fixing frame 24 is rotatably connected to a rotating shaft 25, a seesaw 26 is fixedly connected to the rotating shaft 25, a bending plate 27 is fixedly connected to one end of the seesaw 26, a protrusion 35 is fixedly connected to the upper side of the lifting plate 20, and an impact component 28 is provided in the mounting frame 17 for controlling the lifting plate 20 to quickly drive the driving plate 18 to move downward and impact after moving down to a set height.

[0034] The impact member 28 includes multiple groups of limit blocks 29 installed on the inner wall of the installation frame 17. The limit blocks 29 are located between the driving plate 18 and the impact plate 7. The upper and lower sides of the end of the limit block 29 away from the installation frame 17 are both inclined. A sliding groove 30 is opened in the installation frame 17 and is horizontally slidably connected to the limit block 29. A third spring 31 is fixedly connected to the limit block 29 in the sliding groove 30.

[0035] The limiting member 16 includes an electric telescopic rod 32 fixedly installed in the swing frame 4, and the telescopic end of the electric telescopic rod 32 is fixedly connected to an arc plate 33, and the upper side of the arc plate 33 can fit and contact with the outer wall of the rotating ring 13. A trigger key 34 for driving the electric telescopic rod 32 to extend during the pressing process is fixedly connected to the upper side of the flat floor 1. The outer wall of the rotating ring 13 is evenly provided with multiple groups of triangular grooves 36, and the upper side of the arc plate 33 is fixedly connected to multiple groups of triangular blocks 37 that can be plugged into the triangular grooves 36.

[0036] In this embodiment, the existing excavator is generally connected to the dipper arm 40 through the rotation of the boom 41, and one end of the dipper arm 40 is rotationally connected to the bucket 39, and the swinging and flipping state between the boom 41, the dipper arm 40 and the bucket 39 is controlled and driven by the hydraulic drive component. The boom 41 can drive the dipper arm 40 and the bucket 39 to swing horizontally. When leveling operation is required, the bucket 39 is controlled to be inserted into the area between the two sets of counterweight blocks 38, and the shovel tip is made to fit with the bottom of the bent plate 27. At this time, the connecting rod 14 in the rotating rings 13 on both sides is pushed to the two sides of the dipper arm 40 for fitting, and fixed to the two sides of the dipper arm 40 by bolts to complete the installation.

[0037] The boom 41 and the arm 40 are controlled to swing and move, and the angle between the bucket 39 and the arm 40 is fixed during this process. At this time, the connecting rod 14 can be used to drive the rotating rings 13 on both sides so that the swing frame 4 can drive the flat floor 1 as a whole to move up and down and swing left and right. In the process of movement, since the flat floor 1 is in a balanced state as a whole, the rotating rod will drive the rotating ring 13 to rotate with the arm 40 through the guide groove 15, but the rotating ring 13 and the swing frame 4 will also rotate relative to each other, ensuring that the flat floor 1 is horizontally suspended as a whole under control, and after the swinging stops, the bottom surface of the flat floor 1 will be in a relatively horizontal state, without the need for additional adjustment, thereby greatly improving the efficiency of automatic leveling.

[0038] When bulldozing is required, the flat floor 1 is brought close to a flat position close to the ground, the angle of the boom 40 is adjusted, and then the tip of the bucket 39 is turned downward, and the rocker plate 26 is pushed down to press the trigger key 34, so that the electric telescopic rod 32 is driven, and the arc plate 33 is pushed upward, and the triangular block 37 and the triangular groove 36 are restrained and limited, so that the rotating rod cannot continue to rotate relative to the swing frame 4. After that, the boom 40 is no longer adjusted for rotation, because the rotation of the boom 40 will cause the rotating rod to drive the swing frame 4 and the flat floor 1 to turn over as a whole, affecting the flat floor. The flat floor 1 is in a horizontal state on the ground. After that, the arm 40 can be controlled to swing horizontally only by the vehicle body driving the boom 41, or the arm 40 can be pushed to move with the vehicle body, so that the flat floor 1 and the bulldozer frame 2 can move horizontally at a position close to the ground. In this process, the soil pile above the flat ground can be pushed to the desired position by the bulldozer frame 2, and the bottom surface of the flat floor 1 is always in a relatively horizontal state. Among them, the electric telescopic rod 32 will automatically drive the arc plate 33 to move downward when the trigger button 34 is not pressed, thereby releasing the limit resistance to the rotating ring 13.

[0039] When the ground needs to be compacted and leveled, the leveling floor 1 is moved to the desired position through the dipper arm 40, and then the tip of the bucket 39 is controlled to lift up, so that the bending plate 27 drives the seesaw 26 to rotate around the rotating shaft 25, and the end of the seesaw 26 away from the bending plate 27 moves downward, pushing the protrusion 35 and the lifting plate 20 to move downward together, and the lifting plate 20 pushes the second spring 19. At this time, the bottom of the driving plate 18 is resisted by the limit block 29 and remains fixed. After the second spring 19 is compressed to the set strength, the driving plate 18 will be pressed down and push the limit block 29 through the inclined surface. When the rocker plate 26 is lifted up and the driving plate 18 is moved down, the rocker plate 26 is moved down and the driving plate 18 is moved down, so that the rocker plate 26 moves down and the driving plate 18 moves down, and the rocker plate 26 moves down, so that the rocker plate 16 is moved down and the driving plate 18 moves down, so that the rocker plate 26 moves ...

[0040] After that, the bucket 39 swings down again, and driven by the tension spring 22, the lifting plate 20 and the protrusion 35 move up, the rocker 26 returns to its original position, and the lifting plate 20 drives the second spring 19 to pull the drive plate 18 up, and pushes the limit block 29 to slide again through the inclined surface, and until the drive plate 18 reaches the upper side of the limit block 29 and returns to its original position, under the push of the first spring 12, the lifting frame 11 drives the flat floor 1 to move up and return to its original position, and then the bucket 39 can be used to drive the impact plate 7 to intermittently impact and press down again to improve the compaction density.

[0041] It is worth noting that: before using the device, it is necessary to ensure that the excavator is in a relatively horizontal position. Before installing the flat floor 1, the overall level of the excavator can be judged by the spirit level inside the excavator, and the raised position can be knocked by the bucket 39, and the concave position can be filled. Finally, after the excavator drives to a relatively flat ground, the flat floor 1 and the bucket 39 are installed. After that, the road surface where the excavator drives needs to be compacted by bulldozing and impact before the excavation can be pressed up, ensuring that the excavator is in a relatively stable state during the overall movement process, and at the same time, the swing frame 4 on the dipper arm 40 and the flat floor 1 can be in a relatively horizontal and stable state to work.

[0042] After use, the flat floor 1 is placed at the desired position, the connection between the bolts and the boom 40 is released, and the connecting rod 14 is slid to both sides in the rotating ring 13, and the bucket 39 can be taken out by controlling the boom 40 to move upward, thereby completing the disassembly operation.
