The work aims to develop an assistant device which can improve the efficiency of banana bagging. By studying the process and method of banana bagging, the designed control lifting mobile mechanism and rope collecting bag mechanism were used to complete banana bagging. Ansys and Matlab were adopted to carry out simulation tests. After the feasibility of the mechanism was determined, the physical prototype was made and the field tests were conducted. The success rate of bagging was about 97.4%, indicating that the device could work efficiently. The continuous rate of bagging was over 98.3%, and the device had high reliability in working. Under the condition of continuous bagging of large bananas, the time needed for manual packaging was shortened by more than 51.2%. The electric banana bagging and binding device can assist the staff to complete banana bagging, reduce the labor intensity of the staff and improve the work efficiency.
