[0023] like Figure 1-5 The ramming head for an excavator shown in the figure comprises a main ramming plate 1 and a steel block 11 arranged on one side of the main ramming plate 1, and a pin plate 12 for connecting with the excavator arm is arranged on the steel block 11; a diagonal connecting rod 13 is also arranged on the steel block 11, and one end of the diagonal connecting rod 13 is fixedly arranged on the steel block 11, and the other end is fixedly arranged on the main ramming plate 1; two groups of auxiliary ramming plates 2 for expanding the ramming area of ​​the main ramming plate 1 are also connected to both sides of the main ramming plate 1 through hinges.

[0024] When the device is in use, the bucket of the excavator is first removed from the boom, and the pin-connected plate 12 is installed with the boom by pin connection, and then the tamping operation is carried out. Since the pin-connected plate 12 is arranged on the side portion of the main tamping plate 1, the main tamping plate 1 can be basically aligned with the machine body after being installed on the excavator, so that the operator can easily judge the alignment between the main tamping plate 1 and the soil surface that needs to be tamped when tamping the soil. At the same time, through the arrangement of the inclined connecting rod 13, the main tamping plate 1 will not tilt downward due to the deviation of the installation point.

[0025] Two groups of movable rods 21 are hinged on the two groups of auxiliary ramming plates 2, and a hanging rod 22 is connected between the movable rods 21. A hanging bracket 23 is provided on the main ramming plate 1, and a hanging groove 24 for hanging the hanging rod 22 is provided on the hanging bracket 23; when the hanging rod 22 is hooked in the hanging groove 24, the auxiliary ramming plate 2 is flipped upward relative to the main ramming plate 1, and a limiting frame 3 is also provided on the main ramming plate 1, and a movable latch 31 that can slide in a limited position is provided in the limiting frame 3, and a pin buckle 32 that is adapted to be plugged with the movable latch 31 is provided on the auxiliary ramming plate 2. Through the auxiliary ramming plates 2 on both sides of the main ramming plate 1, the ramming surface of the main ramming plate 1 can be expanded when necessary. By taking the hanging rod 22 out of the hanging groove 24 on the hanging bracket 23, and then sliding the movable latch 31 to make it inserted into the inside of the pin buckle 32, the auxiliary ramming plate 2 is placed down and is in the same plane as the main ramming plate 1, thereby increasing the single ramming area and improving the ramming efficiency.

[0026] In one embodiment, side frame plates 4 are further provided on both sides of the main tamping plate 1 that are not connected to the auxiliary tamping plate 2. Side marking plates 41 are movably connected inside the side frame plates 4. Limit plates 42 are provided at both ends of the side marking plates 41. The lower side of the side marking plates 41 is also provided with sinking grooves 43 that are adapted to and engaged with the limit plates 42. Through the setting of the side marking plates 41, they are suspended downward before the main tamping plate 1 tamps the earth, and can be used as alignment lines on both sides of the main tamping plate 1 to assist the operator in observation and alignment, and then tamping the earth downward. When the main tamping plate 1 tamps the earth downward, the side marking plates 41 can be pressed against the soil surface and slide upward, so that the limit plate 42 at the lower end is retracted into the sinking groove 43 on the side frame plates 4 so as not to affect the tamping operation.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
