Experimental Research Of Branches Feeding Device Of Cerasus Humilis

The feeding device of Cerasus humilis'branches is an important component of the Cerasus humilis harvester. Its performance has a direct impact on the recovery ratio and fruit quality after harvest. Good feeding device can provide good quality assurance in storage and deep processing process.In order to determine the parameters of Cerasus humilis feeding device in feeding process, this paper take Cerasus humilis 4 and Cerasus humilis 5 in fruit garden of Shanxi Agriculture University as examples to analyze the biomechanical characteristics of Cerasus humilis. The main part of picking device, parameters of Cerasus humilis and the fruit quality of device system were analyzed by using related software. Main contents include:(1)Three shaft sizes of Cerasus humilis were statistical measurement. Compression and picking force of Cerasus humilis to be harvested were tested and analyzed by using SANS mechanical testing instrument. Through compressing test, the elastic modulus of Cerasus humilis 4and5 were 0.66 MPa and 0.75 MPa respectively.(2)The maximum stress, strain and vibration mode of the branches output roller were obtained by analysis of static and dynamic using ANSYS software. The results show that the output roller meets the requirements of strength and stiffness in working condition.(3)The maximum impact velocity allowed by fruit picking process and fruit picking roller was analyzed through Hertz contact theory. Cerasus humilis 4 and 5 with picking roller' impact velocity should below 4.87m/s and 6.11 m/s respectively. It provides the design basis for the selection of the speed of fruit picking roller and the guarantee of good quality.(4)Draw the running chart of the fruit picking roller in the working condition by simulate the picking process of fruit picking roller by using ADAMS software and combined with the size of the fruit force in the harvest process. It provides an assurance of the selection of motor and evaluation of stability of fruit picking system in the follow-up work.(5)Using EDEM software to simulate the process of fruits were picked from the branches off into the box by roller. Compared with the fruit drop into the box directly, add the fruit recovery platform is a very important factor to ensure the quality of the fruit.
