The invention relates to an anti-blocking rammer. The anti-blocking rammer effectively solves the problems that vent holes of a rammer head are prone to being blocked, and the compaction strength of the positions, at the vent holes, of the ground is insufficient. According to the technical scheme, the rammer comprises a rammer head, vent holes are formed in the rammer head, a piston hole is formedin the upper end of the rammer head, a first piston is installed in the piston hole, a closed cavity is formed in the rammer head, the first piston pumps air to the upper end of the cavity, a secondpiston is installed in the cavity, an air channel is formed between each vent hole and the cavity, horizontal clamping blocks are installed on the side wall of the cavity, when the lower end surface of the second piston is located above the multiple clamping blocks, the second piston seals ports, located in the cavity, of the multiple air channels, and after the second piston crosses the multipleclamping blocks to move downwards, the ends, located in the cavity, of the multiple air channels are opened. The rammer has the advantages that the vent holes can be automatically dredged and can be effectively prevented from being blocked, so that the fine and dense vent holes can be designed in the rammer head, bumps are prevented from being formed at the positions of the large-diameter vent holes, and the ramming quality is improved.
本发明涉及一种防堵夯锤，有效的解决了锤头通气孔容易堵塞，通气孔处地面夯实力度不足的问题；解决的技术方案包括锤头，锤头上开有通气孔，锤头上端开有活塞孔，活塞孔内安装有第一活塞，锤头内开有一个密闭的空腔，第一活塞和向空腔上端泵气，空腔内安装有一个第二活塞，每个通气孔与空腔之间均开有一个气道，空腔侧壁上安装有水平的卡块，第二活塞的下端面位于多个卡块上方时，第二活塞将多个气道的位于空腔内的端口封闭，当第二活塞越过多个卡块向下运动后，多个气道位于空腔内的一端开启；本发明能够对通气孔自动疏通，有效的避免通气孔堵塞，因此可以在锤头上设计细而密的通气孔，避免大直径通气孔位置形成鼓包，提高夯击质量。
