Description
Technical Field
The invention relates to a saw blade device of a combined rock breaking tool bit, and belongs to the technical field of dredging equipment.
Background
With the further development of shipping industry in China, the requirements of port, channel, wharf and other infrastructure are increased day by day, the dredging industry is gradually developed with the trend of shipping industry development, but the dredging equipment of the dredging industry faces more and more tests and is more and more severe. When a dredger is used for construction operation, the dredger inevitably contacts with obstacles which are difficult to remove, such as reamer blades and drag heads of coral reefs and granites. The direct rock breaking by the blasting method has the problems and disadvantages of large dynamic and static, pollution, higher mechanical automation difficulty, various operation steps and the like. The direct rock breaking action of the breaking hammer is small in movement and static, pollution is basically avoided, energy is saved, environment is protected, the breaking hammer can be used for directly excavating, the construction period is effectively shortened, and the rock breaking efficiency is improved. However, after the breaking hammer breaks the rock, other equipment such as a grab dredger and a backhoe dredger is still needed to clean the broken rock. The high-pressure water jet rock breaking has no cutter abrasion, does not generate dust and sparks, and is easy to realize centralized control. However, the high-pressure water jet requires a high-pressure water pump as a precondition, and the energy consumption is large. For softer substances such as ordinary silt at the bottom of the water, the multifunctional dredger directly utilizes the reamer to suck the substances out and directly and accurately discharges the substances to a final settlement area through the dredge pump; when the soil is very hard or contains large rocks or other objects with large dimensions unsuitable for pumping, the multi-function dredger is switched to a backhoe dredging operation, similar to a land backhoe, which directly lifts the materials and then pours them into a transport vehicle (ship) and performs the related work. However, when continuous hard rocks in a certain area are encountered, the multifunctional dredger only utilizes the hydraulic hammer to crush the rocks to reduce the volume of the rocks to a value capable of being shoveled by a backhoe, then changes the working device from the hydraulic hammer to the backhoe, and then carries out the backhoe operation, thereby finally completing the dredging of the rocks. The method can not realize the integration of rock breaking, rock suction and rock transportation, is inconvenient to operate, and has lower production efficiency and higher production cost.
