Design of a Rotary Sprout Harvester

In order to solve the issues such as high labor intensity, low work efficiency as well as bad reaping quality regarding manual sprout harvesting, realization of feeding of sprouts by self-weight for the existing sprout harvester and manual collection required for reaped sprouts, a type of rotary sprout harvester has been developed. This article, based on SolidWorks software, sets up 3D models of parts and complete unit of the rotary sprout harvester, the mathematical model of kinematic analysis of the cutter of double eccentric circular cam mechanism, and draws variation curve of displacement, speed and acceleration by Matlab. As for the rotary sprout harvester based on this design, the results of the application tests show that time for single round of reaping is 12s, which compared with manual reaping, increases work efficiency by more than 300% with fine harvesting quality; via the transmission device and the feed box, automatic connected sprout feeding and collection of reaped sprouts are realized. If the rotary sprout cutter in this design is applied to sprout reaping, labor intensity can be reduced, work efficiency increased and operation quality guaranteed. Besides, as such mechanism is characterized by simple structure, convenient operation, safety and low manufacturing cost, it solves the issue of mechanization of sprout reaping, thus easy to be promoted in production.
