high altitude gap spray rod spray frame;;lifting mechanism;;folding mechanism;;finite element analysis

Aiming at the problem of low spray width of spray rod sprayer and poor stability of spray rod folding,a wide range of high altitude gap spray frame is designed. Theoretical analysis and mechanism design of lifting mechanism and folding mechanism of spray frame are carried out,and three-dimensional model including central spray frame,parallelogram lifting mechanism,mounting seat and spray rod folding mechanism are established. In order to verify the rationality and reliability of the summation,the static analysis of the jet rod under working state was carried out by Ansys finite element analysis software. The analysis results show that the maximum stress is 152.7 MPa,the maximum deformation of the rod is the largest,the maximum distortion is 4.6 mm,and the minimum safety factor is 1.63,which accords with the design requirement. The site test verifies the prototype further,and the test shows that the design satisfies the work requirement.
