| Abstract: |
| 【Objective】 In view of the characteristics that landscape waterfronts are increasing,small in size,dispersed,and difficult to harvest weed for large harvester,SCSGJ-2.6 type harvester of aquatic weed was developed for small waterfront.【Method】 Based on the predetermination of the swath,the cut depth,the machine's outline size,productivity,hydrostatic speed,the minimum turning radius,and other technical parameters,the design of this harvester was accomplished.The main components,layouts and working principles of the harvester were introduced.Then the power device,hull,propeller,reciprocating cutters,conveyor belt,drive mechanism and auxiliary structures were selected or designed based on the knowledge of hydrodynamics,structural mechanics and theoretical naval architecture and so on.【Result】 Tests showed that SCSGJ-2.6 type harvester's turning radius was 1.5 m,the cutting depth adjustable between 0-0.475 m,the productivity 1.5 t/h,time consumption of turning 1.5 minutes in a 5 m-wide river,average omission 3%,average cutting leakage rate 5%,oil consumption 1.46 L/h,thus all the parameters met the goals.【Conclusion】 The tests proved that the harvester has a good ability for continuous cutting and harvesting,and in view of the developing characteristics of landscape waterfronts:small in size and huge in number,abroad application prospect of this harvester of aquatic weed is expected. |
