The invention provides a breaking hammer with a short drill rod structure, which comprises a mounting base, a drill rod fixing body fixed on the mounting base, a drill rod mounted in the drill rod fixing body in a manner of moving up and down, a hammerhead arm with one end hinged on the mounting base, striking iron fixed in the hammerhead arm and a driving cylinder, the driving cylinder is of an inverted structure, and the driving rod extends downwards from the lower end of a cylinder body of the driving cylinder. In the vertical direction, the driving cylinder, the hammerhead arm and the drill rod fixing body are arranged in series from top to bottom, and the hinge point of the driving cylinder and the mounting base and the hinge point of the driving cylinder and the hammerhead arm are located on the upper side of the drill rod fixing body. The impact of the stroke of the driving cylinder on the length of the drill rod fixing body is thoroughly eliminated, the lengths of the drill rod fixing body and the drill rod are reduced to the minimum, and the raw material cost, the manufacturing cost and the use cost of the breaking hammer are reduced; the lighter the weight of the drill rod is, the faster the falling speed of the drill rod is, and the striking force of the drill rod to rock is increased.
本发明提供一种短钎杆结构的破碎锤，包括安装基座、固定于安装基座的钎杆固定体、可上下移动地安装在钎杆固定体中的钎杆、一端铰接在安装基座上的锤头臂、固定在锤头臂中的打击铁、以及驱动缸，驱动缸具有能够伸缩的驱动杆，驱动缸为倒置式结构，驱动杆从驱动缸缸体的下端向下伸出；在上下方向上，驱动缸、锤头臂和钎杆固定体从上至下串联式排列，驱动缸与安装基座的铰接点、以及驱动缸与锤头臂的铰接点都位于钎杆固定体的上侧。本申请彻底消除驱动缸的行程对钎杆固定体的长度的影响，将钎杆固定体和钎杆的长度降到最短，降低破碎锤的原材料成本、制造成本和使用成本；钎杆的重量越轻，钎杆的下落速度就越快，增加钎杆对岩石的打击力度。
