Constant-force comb falling cutter with self-adaption to banana fruit shafts based on extensible mechanism

Abstract

The invention discloses a constant-force comb falling cutter with self-adaption to banana fruit shafts based on an extensible mechanism. The comb falling cutter comprises a comb falling cutter head, linear guide rails, sliding blocks, main hard cutter connecting blocks, main hard blades, auxiliary hard blades, a connecting rod, soft blades and constant-force assemblies; a plurality of linear guiderails are radially and uniformly distributed on the comb falling cutter head around the center of the through hole of the comb falling cutter head; a sliding block is mounted on each linear guide rail in a sliding manner; the top of each sliding block is connected to a main hard cutter connecting block; one side, close to the center of the comb falling cutter head, of each main hard blade connecting block is connected to a main hard blade extending upwards, and an auxiliary hard blade is arranged between every two adjacent main hard blades; the top of each main hard blade and the top of eachauxiliary hard blade are each provided with a transverse soft blade; and each sliding block is connected to a constant force assembly. The comb falling cutter can effectively solve the problems that existing cutters are poor in self-adaptation to banana fruit shafts, have small variable-diameter stroke, and have too large gap.

Description

technical field [0001] The invention relates to the technical field of self-adaptive banana fruit shaft combing, shaft profiling and combing, fixed center, large stroke and diameter change, especially a constant force combing cutter based on an adaptive banana fruit shaft based on an expandable mechanism. Background technique [0002] At present, although the few mechanical combing cutters at home and abroad can complete the combing and combing of 2 to 3 combs of bananas, the overall work efficiency is low, the adaptability to the banana fruit shaft is poor, and the combing quality is poor. And because there are generally 7 to 8 combs growing on the whole bunch of banana fruit shafts, the diameter of the fruit shaft from the first comb to the tail comb is about 41.8 to 81.0 mm. At present, the existing combing cutters cannot realize if the shaft diameter range is large. The diameter is variable, so only 2 to 3 combs can be combed one by one, and there is a large gap between ...
