哈密瓜在线检测输送翻转装置的设计与试验

针对目前新疆哈密瓜的检测分级人工劳动强度大,生产成本高且生产率低的问题,设计了一种用于哈密瓜在线检测的输送翻转装置。该装置由双节距链条,输送翻板,翻板底座等组成。通过哈密瓜输送翻板静应力仿真分析,得到输送翻板的最大应力是7.8566×10-2MPa,材料许用应力为105MPa,最大应力小于许用应力,符合机械设计要求。完成装置样机制作后进行哈密瓜输送翻转装置三因素三水平正交试验,试验结果表明该翻转装置翻转卸料时的最佳组合为:电动机转速n为3r/min;电磁推杆的最佳行程时间t为1.8s;输送翻板支撑杆角度θ为15°。

Design and Test of On-Line Inspection and Turnover Device of Hami Melon

In order to solve the problem of high labor intensity,high production cost and low productivity of Hami melon inspection and grading,a kind of transport turning device was designed.The device consist of double pitch chain,transport flap,the flap base and so on.Through stress simulation analysis,The maximum stress of the conveying flap is 7.8566×10-2 MPa,The allowable stress of the material is 105 MPa,compared the maximum stress with the allowable stress,the maximum stress is smaller than the allowable stress of the material.So the design of the device reaches the requirement of the mechanical design.After completing the prototype of the device,Perform a three-level three-factor orthogonal experiment of the device,the experiment results show that the optimal combination of the device when discharging is:the motor speed n is 3r/min;the optimal travel time t of the electromagnetic push rod t is 1.8 s;the conveying flap support rod angleθis 15°.
