Description

Technical Field

[0001] The utility model belongs to the technical field of foundation compaction equipment, in particular to a rammer for an excavator. Background Art

[0002] In construction, large self-propelled hydraulic tamping machines, manual hand-held mobile tamping machines, manual tamping, etc. are usually used to compact the foundation. In on-site construction, for local small-area foundation pits, it is usually necessary to replace the gun head tamping hammer on the excavator arm for compaction. The gun head tamping hammer used for excavators on the market generally uses a standard gun head tamping hammer that can be purchased directly. The standard gun head tamping hammer consists of a connecting rod and a tamping disc. One end of the connecting rod is fixedly connected to the excavator arm through a connecting piece, and the other end of the connecting rod is fixedly connected to the tamping disc. The excavator controls the gun head tamping hammer to move up and down to compact the foundation.

[0003] The existing public patent (publication number CN 219952091 U) discloses a rammer structure of an excavator, and particularly relates to the technical field of foundation compaction equipment. It includes a connecting rod and a rammer disc coaxially connected to one end of the connecting rod, and also includes a rectangular rammer plate arranged on the side of the rammer disc away from the connecting rod. A plurality of clamping and fixing blocks are evenly distributed on the rectangular rammer plate around the axis of the rammer disc, and a clamping notch that is adapted to engage with the rammer disc is provided on the side of the clamping and fixing block close to the rammer disc.

[0004] Although the above rammer structure improves the practical performance, it still has insufficient overall stability and low overall strength in actual use. To this end, we provide an excavator rammer to solve the above problems. Utility Model Content

[0014] The utility model provides a wedge-shaped piece to connect and fix the receiving ring and the connecting piece. The structural strength of the wedge-shaped pieces is high, and the structural stability of the wedge-shaped pieces and the receiving ring can be maintained. The receiving ring is used for welding and fixing the tamping plate, and under the fixing action of the second reinforcing piece, a stable overall structure is formed.

[0015] When the ramming plate contacts the ground, the counter-impact force received by the ramming plate itself is transmitted upwards, and the second reinforcement piece reinforces the connection between the ramming plate and the receiving ring to reduce the possibility of breakage.
