Problems solved by technology

[0002] At present, only one drill rod can be installed on the breaker. In order to adapt to various working conditions, drill rods of different specifications need to be used. If it is used for excavation and trenching of various soft and neutral layered rocks, it needs One-head drill rods, if they are used for crushing fine-grained and neutral concrete and soft non-layered rocks, cross-head drill rods, etc. are required, and different types of drill rods are sometimes used in one operation. If the method of frequent replacement of the drill rod is used, it will be time-consuming and there will be safety hazards

Embodiment Construction

[0018] Example, see as Figure 1 to Figure 4 As shown, a hydraulic breaker with multiple drill rods includes a hammer body 11, the front end of the hammer body 11 is connected with an output drill rod 12, the front side of the output drill rod 12 is provided with a switching disc 21, and the switching disc 21 is hinged. On the hinge base 22, the hinge base 22 is fixedly connected to the hammer body 11 through the connecting arm 23, and the switching disc 21 is evenly distributed with three crushing actuators 3, the output drill rod 12 and one of the crushing actuators 3 The crushing drill rod 31 is arranged coaxially. The switching disc 21 is provided with a driving mechanism 4 to drive it to rotate. The driving mechanism 4 drives the switching disc 21 to rotate to switch between one of the other two crushing actuators 3 and the output drill. The rod 12 is connected.

[0019] Furthermore, the crushing actuator 3 also includes a crushing drill rod guide seat 32. The crushing dril...

Abstract

The invention discloses a multi-drill-rod hydraulic breaking hammer. The multi-drill-rod hydraulic breaking hammer comprises a hammer body, wherein an output drill rod is connected to the front end ofthe hammer body, a switching circular disc is arranged on the front side of the output drill rod and hinged to a hinge base, the hinge base is fixedly connected with the hammer body through a connecting arm, and three breaking executing mechanisms are evenly distributed on the switching circular disc; and the output drill rod and a crushing drill rod of one of the crushing executing mechanisms are coaxially arranged, the switching circular disc is provided with a driving mechanism for driving the switching circular disc to rotate, and one of the other two crushing executing mechanisms can beswitched to be connected with the output drill rod by driving the switching circular disc to rotate through the driving mechanism. According to the multi-drill-rod hydraulic breaking hammer, the threecrushing executing mechanisms can be switched to be connected with the output drill rod correspondingly, so that the requirements of different working conditions can be met, and switching is convenient and fast.

Description

Technical field [0001] The invention relates to the technical field of breaking hammers, in particular to a multi-drilling rod hydraulic breaking hammer. Background technique [0002] At present, the breaking hammer can only be installed with one drill rod. In order to adapt to various working conditions, different specifications of drill rods are required. If it is used for excavation and trenching of various soft and neutral layered rocks, it needs to be used. If the flat-head drill rod is used for the crushing of fine-grained and neutral concrete and soft non-layered rock, cross-head drill rods and so on need to be used. Sometimes different types of drill rods are used in one operation. If the method of frequently replacing the drill rod is used, it will be time-consuming and there will be safety risks. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a multi-drilling rod hydraulic breaker, whic...
