Abstract

The invention discloses a coconut picking machine. The coconut picking machine mainly comprises picking tongs which are connected with the upper end of a swing arm assembly through a machine head connecting rod. The picking tongs comprise a stepping motor, a servo motor, a lead screw, a conical sliding sleeve, a cylindrical step sliding sleeve, an inner hand grab, an outer hand grab and a bearing. One end of the lead screw is connected with a rotating shaft of the stepping motor, and the other end of the lead screw is connected with the servo motor. The conical sliding sleeve and the cylindrical step sliding sleeve are arranged in the middle of the lead screw in a sleeved mode and are in thread fit with the lead screw. The front grab portion of the outer hand grab is movably connected with an outer ring of the bearing, and the back end portion of the outer hand grab is in sliding contact with the conical surface of the conical sliding sleeve through a roll ball. The front grab portion of the inner hand grab is movably connected with an inner ring of the bearing, the back end portion of the inner hand grab is in sliding contact with an inner cambered surface of the cylindrical step sliding sleeve, and a rotating shaft of the servo motor is fixedly connected with the inner hand grab. Manual picking is replaced by the coconut picking machine, the picking labor intensity is reduced, the picking efficiency is improved, and the safety of the picking operation is improved.

Description

technical field [0001] The invention relates to a fruit picking device, in particular to a coconut picking machine. Background technique [0002] Coconut has high edible value and medical value, and its cultivation has strong regional characteristics. Foreign countries mainly include the Philippines, Indonesia, Malaysia, etc., while domestically, Hainan Province is the only large-scale production area in my country. Coconut tree is an evergreen tree with a straight trunk and a height of 15-30m. Therefore, every coconut harvest season, coconut farmers will have a headache because of the difficulty in picking coconuts. At present, the methods of coconut picking mainly include artificial climbing and picking and cutting and picking with picking machine cutters. Manual climbing and picking is labor-intensive, low-efficiency, and there is no guarantee for the life of the operators; the cutting and picking operation of the picking machine tool is complicated, and a little neglige...
