11 A New Boom Mechanism Design for Corn Sprayer
Download citation file:
A combination boom mechanism for corn sprayer has been developed in this paper. The new-designed boom mechanism included horizontal boom, vertical boom, flexible connection, branch boom and stir wings. With the combination of the theories and methods of spray distribution uniformity, effective spray droplets coverage, and image processing in MATLAB, the length of the vertical boom and fixed angle of the branch boom were determined as 1200mm and 20°, and the spray scale of combination boom in the vertical plane was 1150mm. Using this combination boom mechanism, the corn plants met an all-direction spray, not only the upper part, but also the middle-lower part of the corn plants were sprayed, and the reverse side of the leaves of plants ould meet more spray droplets, so better spray results was achieved.
