RESEARCH ON AUTOMATIC LANE SWITCH OF BANANA TRANSPORT SYSTEM

The method of transporting bananas on hanging rails is the most effective and economical in concentrated banana plantations. Currently, the hanging rail systems for transporting banana bunches use the power source as the tractor cabin hanging on the rails, the turning of the switch to change lanes is completely done manually. This paper introduces the research results of the automatic turning system controlled from the tractor cabin. Based on the selected principle, the mass and position of the counterweight have been calculated to ensure the unstable balance point at the rotation angle of the rotary switch φ = 300 specifically: Counterweight weight 25.45 N; Lever arm ld = 300mm; initial tilt angle compared to the vertical 600; holding moment at the end and beginning positions is about greater than 4,745 Nmm. Normal reaction force on the switch control lever: FN = 72 N. Vertical Fz = 59 N and horizontal Fx = 42 N. The tilt angle of the car when controlling the switch is below 30 is within the allowable range.
