Constant force mechanism based banana harvesting device capable of automatically adapting to banana tree stem

Abstract

The invention discloses a constant force mechanism based banana harvesting device capable of automatically adapting to the banana tree stem. The device comprises a frame, an outer cutter head, an inner cutter head, a first fixed shaft, a second fixed shaft, a first elevating stop block, a second elevating stop block, a torsional spring, a fixed rack, a hard blade installation rack, a movable guiderod, a horizontal compression spring, a public column, an inclined compression spring, a hard blade, and a soft blade. The annular inner cutter head and the outer cutter head can rotate around the axes of the inner cutter head and the outer cutter head and sequentially arranged on the through hole of the frame. Multiple annular arrays of the fixed rack are arranged on the inner cutter head. The fixed rack and the hard blade installation rack are connected by the movable guide rod. The horizontal compression spring sleeves the movable guide rod. The public column is connected to the hard bladeinstallation rack through the inclined compression spring. The hard blade is mounted on the hard blade installation rack. The soft blade is rivetingly arranged on the external side of the hard bladeso as to form an annular enveloping structure that envelopes a banana spike. The provided device has the advantages that the device can automatically adapt to the banana tree stems and in a certain constant force displacement range, the clamping force is constant.

Description

technical field [0001] The invention relates to the technical field of banana deshafting and combing, in particular to a banana combing device based on a constant force mechanism that can adapt to banana stems. Background technique [0002] At present, manual combing is basically used for combing bananas. Although the few mechanical combing devices in China can complete the combing work of single-combed bananas, the work efficiency is low, and the quality of the banana comb handle is poor. In the case of cutting loose fruit combs, cutting fruit fingers, etc., it is impossible to comb the bananas on the whole bunch of spikes one by one, remove the shaft and comb, and the clamping force of the tool on the spikes increases with the increase of the diameter of the spikes. In addition, Also can't accomplish the combing of the banana at the curved ear stalk place, that is to say that the existing mechanical combing device is less effective at the radial adaptability and bending ad...
