Abstract:
In view of the complex terrain of the mountain orangery and the difficulty of working on the cutterhead,an orange garden profile mower cutter was designed. The cutter adopted a freeswinging knife design and had an obstacle avoidance function to reduce the damage which the knife is injured by the obstacle of orange garden. The logarithmic spiral function model of the file blade was established by theoretical analyses and optimization design. The multifactor test analysis of the cutter was carried out with bench test. The optimal combination of parameters including the cutter disk speed of 1 900 r/min,the blade length of 72 mm,the blades number of 4 were obtained with comprehensive scoring method. The verification test was carried out to verify the rationality and effectiveness of the test. Compared with the optimal value in the orthogonal test group,the peak torque decreased by 0.38%,and the uniformity of one cut increased by 5.43%. The test achieved the expected results and met the requirements for weeding in mountain citrus orchards.
