Banana combing platform based on rigid-flexible coupling parallel mechanism

Abstract

The invention discloses a banana combing platform based on a rigid-flexible coupling parallel mechanism. The banana combing platform comprises a combing cutter disc, parallel four-bar linkages, a guide rod, connecting rods, a crank, a power source, an annular enveloping cutter, a top plate, a bottom plate and the rigid-flexible coupling parallel mechanism. A plurality of guide grooves are formed in the combing cutter disc in the circumferential direction of the combing cutter disc. Each guide groove is correspondingly provided with one parallel four-bar linkage. The multiple parallel four-barlinkages form an annular diameter-variable extensible mechanism. The annular enveloping cutter is arranged on the extensible mechanism. The top plate is arranged on the bottom face of the combing cutter disc. The bottom plate is arranged under the top plate and connected with the top plate through the rigid-flexible coupling parallel mechanism. The annular enveloping cutter can rotate or move in space according to bending change of banana fruit spike shafts through the rigid-flexible coupling parallel mechanism, and the annular enveloping cutter can adapt to bending of the banana fruit spike shafts in a self-adaptation manner. The banana combing platform can effectively solve the problems that an existing mechanical combing device is poor in self-adaptation enveloping effect on the bananafruit spike shafts, and the profiling attachment degree is not high.

Description

technical field [0001] The invention relates to the technical field of banana self-adaptive profiling combing, in particular to a banana combing platform based on a rigid-flexible coupling parallel mechanism. Background technique [0002] At present, the existing banana combing basically adopts manual or mechanical combing device to comb the bananas. Manually combing bananas is low in efficiency and dangerous, and the bananas are seriously damaged during the operation, which is not conducive to the preservation, transportation and fresh sales of bananas. Although the existing mechanical combing device can complete the combing work of bananas, the quality of the combing is poor. For banana cobs with irregular geometric shapes, it still has poor adaptive envelope effect and low profiling fit. Problems such as these greatly affect the incision quality and fruit quality of banana mechanical fall combing, and are also unfavorable for banana preservation, transportation and fresh...
