Flow-controllable jetting soil breaking device
A flow-controllable jetting soil breaking device comprises a waterway switching unit, a soil breaking unit and a swing unit which are all sequentially connected. A plurality of water supplying channels and valve elements of the water supplying channels are arranged in the waterway switching unit. Each valve element is provided with an angle sensor so that flow can be accurately controlled. Water flow flows from the waterway switching unit and is sprayed out of the soil breaking unit. According to the device, on the premise that lift and flow are not increased, segmented concentrated soil breaking at different heights in a submarine trench is achieved through segmented switching of waterways; segmented concentrated use can be performed on supplied water of existing water pumps while the number of the water pumps is not increased and the capacity of the water pumps is not improved, and therefore power, system complexity and cost increase caused by increase of the water pumps are reduced; and due to the fact that segmented concentrated use is performed on supplied water of the existing water pumps, the using efficiency of an existing device is improved, hydraulic driving is adopted for the system, and maintenance is easy.
