水果分選機的設(shè)計
摘 要：本文分析了中國國內(nèi)外水果分級分選機的研究和發(fā)展現(xiàn)狀，對未來進行了展望，設(shè)計出了一種新型水果分級分選機構(gòu)。該水果分級分選機是由分級滾筒、傳動機構(gòu)和電動機組成。采用電動機提供動力，通過帶輪傳動機構(gòu)，將運動和動力傳送到直齒圓柱齒輪減速器，然后再通過鏈輪傳動機構(gòu)，將所需的運動和動力傳送至分級滾筒上，從而實現(xiàn)水果的分選。整個機構(gòu)簡單且易于操作，便于維護，提高了生產(chǎn)效率，降低了勞動強度，為實現(xiàn)水果加工機械化與規(guī)?；峁┝饲疤?。

The design of fruit sorting machine
Abstract: This paper analyzes the present situation of the Chinese domestic and foreign fruit sorting machine research and development, on the future prospects, we design a new type of fruit sorting mechanism. The fruit sorting machine is composed of grading cylinder, transmission mechanism and a motor. The power provided by a motor, through a belt pulley transmission mechanism, the movement and power is transmitted to the straight tooth cylindrical gear reducer, and then through the chain wheel transmission mechanism, the required movement and power is transmitted to the classification on the drum, thereby we can realize the separation of fruit. The entire mechanism is simple and easy to operate, easy to maintain, improve production efficiency, reduce labor intensity, which help to achieve the fruit processing mechanization and scale and to provide the premise.
Key Words: fruit; shape; the grading mechanism; grading cylinder
